A pasting roller has brush bristles planted in a surface thereof in straight lines or spirally to form a plurality of rows at predetermined intervals on the roller surface. An adhesive sheet S is pasted to work while moving the pasting roller and the work, which is the recipient, relative to and crossing each other. In this pasting process, a rotating speed of the pasting roller is adjusted according to a surface configuration of the work to render the pressure on the adhesive sheet constant.

Disclosed is a ventilation device (10, 30, 50, 70) for discharging water vapor from the interior (8) of a housing of a vehicular lamp (1) to the outside of the housing (2), wherein: a ventilation path that is bent and is in communication with a ventilation opening (9) in the housing is formed; and, up to the terminal end of the ventilation path including the bent part, the ventilation path maintains a minimum cross-sectional area with which it is possible to maintain a fogging reduction rate of 80% or higher in a lapse of 5 minutes. Thus, a defogging property inside the housing is improved while preventing the infiltration of liquid water and external substances by employing the ventilation path having a bent part.

An optical measurement device and method of use provides non-invasive physiological measurements from a predetermined location on a body part of a user. The optical measurement device provides an illumination and detection assembly configured to generate and detect light of a predetermined wavelength range in the form of a photoplethysmography (PPG) signal, as well as a pressure detection assembly configured to detect an amount of pressure applied to the measurement device by the user being measured. A feedback unit, such as a portable display device, can be coupled to the measurement device to provide the user with real-time feedback of the detected PPG signal and level of applied pressure so that the user may adjust the amount of applied pressure to improve the quality of the detected PPG signal.

A housing kit (90) includes a housing body (20) and a ventilation member (10). The housing body (20) has a vent hole (21). The ventilation member (10) has a leg portion (26). The leg portion (26) is a portion adapted to be inserted into the vent hole (21). The housing body (20) has an inner peripheral surface (23) that defines the vent hole (21). The inner peripheral surface (23) includes a first rounded segment (23_(R1)), a first straight segment (23_(S1)), a second rounded segment (23_(R2)), and a second straight segment (23_(S2)) that are formed in order from an exterior space (24) side to an interior space (22) side of the housing body (20). The first rounded segment (23_(R1)) and the second rounded segment (23_(R2)) each form a curve convex toward a central axis (O) of the vent hole (21) in a cross section of the housing body (20) including the central axis (O). The first straight segment (23_(S1)) and the second straight segment (23_(S2)) each form a straight line in this cross section.

Disclosed is a ventilation device (10) that discharges water vapor within a housing of a vehicular lamp to the outside, and that includes: an attachment part (11) to be attached in communication with a ventilation opening in the housing; and a ventilation path (20) that is a hollow formed from the upstream side toward the downstream side, and that has a bent part which bends from a first direction (P) to a second direction (Q). In the ventilation path (20): the cross-sectional area S3 of a cross section orthogonal to the second direction (Q) on the downstream side is constituted by making the cross-sectional area S2 of a cross section orthogonal to the first direction (P) on the entrance side of the bent part larger than the cross-sectional area S1 of a cross section orthogonal to the first direction (P) on the upstream side, and making the length, in the first direction (P), on the exit side of the bent part which is bent from the cross-sectional area S2 shorter than the length, in the second direction (Q), of the cross-sectional area S1; and thereby, cross-sectional area S1 cross-sectional area S3.
