An object of the present invention is to provide a more compact processing apparatus than previously available. Provided is a processing apparatus for unfurling or folding a processing subject (T), including a pair of retaining devices (310A, 310B) capable of retaining the processing subject (T), a carrying device (402) capable of carrying the processing subject (T) such that a part of the processing subject (T) hangs down therefrom while the processing subject (T) is retained by at least one of the pair of retaining devices (310A, 310B), and a control device that controls movement of the retaining devices (310A, 310B) and the carrying device (402), wherein the control device rotates the carrying device (402) in a condition where the retained processing subject (T) hangs down from the carrying device (402).

A communication unit prevents a malfunction which initiates communication against a users will when communication for the purpose of remote dialogue, without requiring a complex operation on the part of the user. This communication unit, used when a sender transmits his or her image or speech information to a recipient, comprises: a device that acquires image and speech information; a home server that transmits communication data indicating the information acquired by the information acquisition device to a device possessed by the recipient; and a detection unit that detects an object to be detected which is generated or changed by an action of the sender. The detection unit detects mutually different types of the objects each to be detected. Then, the home server starts transmitting the communication data when each detection result from each of two or more types of the detection units satisfies a predetermined condition.

Background: Recently, we evaluated factors responsible for falling, including walking speed evaluated with the use of originally designed, suddenly narrowed paths, in patients with Hoehn-Yahr stage III PD. We prospectively studied the same cohort of patients with PD who were followed up for 2 years, to determine predictors of future falls. Methods: We performed clinical assessments and evaluated balance in 26 patients. A total of 19 variables including PD-related independent variables, balance investigation-related independent variables and gait independent-related variables were evaluated. Results: The Frontal Assessment Battery (FAB) score (p = 0.002), Tinetti balance (p = 0.009), and gait velocity (p = 0.001) were higher in fallers than in non-fallers. On multiple logistic regression analysis, the FAB score was related to falling (odds ratio = 3.328, p = 0.033, 95% confidence interval = 1.104-10.03). On the FAB, the scores of 'inhibitory control' and 'sensitivity to interference' were significantly lower in fallers than in non-fallers. Conclusions: The use of the originally designed, suddenly narrowed path was the primary reason for demonstrating for the first time that a low FAB score is a risk factor for future falls. Calculation of the FAB score may be useful for predicting the risk of future falls. © 2014 S. Karger AG, Basel.

Earthquake Spectra | Year: 2015

The damping correction factors (DCFs) to convert the 5% damping acceleration response spectra to those for other damping levels are computed for the records of 13 Japanese earthquakes. Their correlation with the standard deviation of phase difference (σ) is also investigated in ten frequency bands. The σ-DCF relations obtained are found to be very similar across the different types of earthquakes. Further, regression analysis suggests that for damping ratios of 1% and 2%, with the increase in σ, the DCFs increase in low-frequency bands (up to 4-5 Hz), whereas they decrease in higher frequency bands. On the other hand, for damping ratios of more than 5%, with the increase in σ, the DCFs decrease in low-frequency bands (up to 1 Hz), whereas the opposite tendency is observed in higher frequency ranges. This research also discusses the applicability of the σ-DCF relations to design ground motion simulation. © 2015, Earthquake Engineering Research Institute.

The causality of natural ground motions is evaluated through statistical values for the phase difference. The causality is expressed in terms of the Hilbert transform relationship between the real and imaginary parts of the Fourier transform of the ground motion. We find that ground motions with a shorter duration have a higher degree of causality. Furthermore, we propose a ground-motion simulation algorithm that incorporates causality. The simulated ground motions, compatible with design response spectra, have almost the same spectrum conversion factors as those estimated from natural ground motions. Copyright © A. S. Elnashai.

Gaps, slits, and openings for natural ventilation that occur around doors and windows cause sound leakage and decrease sound insulation performance. However, if airtight materials are used to close these gaps, as is typical, the ventilation performance is lost. In the gaps, the particle velocities become large, and this phenomenon is reported as the "gap effect." Furthermore, it is suggested that the sound insulation performance is improved by suppressing the particle velocities in the gaps with breathable sound-absorbing materials. Therefore, a balance between the suppression of sound leakage and maintaining the air ventilation is obtainable by considering the balance between the total equivalent clearance and the flow resistivities of the breathable sound-absorbing materials. In this study, for the installation of thin nonwoven fabrics as a breathable material in the gaps, improvements in the sound insulation performance and the amount of ventilation as the total equivalent clearance area are verified. Additionally, the relations between the sound insulation performance and the air ventilation performance using these nonwoven fabrics in the gaps are discussed. As a result, an improvement in the sound insulation performance is obtained while maintaining the air ventilation performance by installing thin nonwoven fabrics that have low flow resistivities because the large particle velocities are effectively suppressed in the gaps. © 2015 Elsevier Ltd.

Unintended gaps that occur around door sets and windows cause sound leakage and decrease sound insulation performance. In the Boundary Element Method (BEM) analysis, sound transmitted through a gap is expressed as the integral of the particle velocity. This means that the transmitted sound field can be expressed based on the particle velocity at the gap only. Hence, it is demonstrated here through numerical analysis that a decrease in sound insulation performance is caused by an increase in sound particle velocities in the vicinity of gaps in a rigid wall. We call this phenomenon the "gap effect". It is also shown that the movement of particles around the gaps can be suppressed by installing a thin sound-absorbing material such as thin or nonwoven fabric, reducing the sound leakage from the gaps. Furthermore, the sound insulation performance obtained by suppressing the particle velocities at the gaps is experimentally verified. The results of this study show that the improvement observed in the sound insulation performance following the installation of sound-absorbing layers into the gaps is quite significant and is suitable for practical use. © 2015 Elsevier Ltd.

A system and method are provided to hold a dialogue between communicators while the communicators are viewing their images each other and which prevents the presence of an image display screen from being noticeable in a non-communication state. A first unit for the communicator generates and transmits first data indicating the image of the communicator. A second unit for the communication partner expands the first data received via a communication line to display the image of the communicator on the display screen, and generates and transmits second data indicating the image of the communication partner in front of the display screen. A human sensor is configured to detect that the communication partner is at a predetermined position in a home. Only during the period of the human sensor detecting that the communication partner is at the predetermined position, the display-cum-mirror forms a display screen, and otherwise, a mirror.
