An algae culture method capable of efficiently producing an osmotic pressure adjusting substance, a production method of the substance, and an algae culture method for recovering carbon dioxide from a mixed gas containing carbon dioxide and sulfurous acid gas. The methods involve preparing a plurality of enrichment cultures each containing betaine by culturing a culture of microalgae derived from an environmental specimen under a photoautotrophic condition and under a plurality of culture conditions; making a cultivation plan in which an optimum enrichment culture suitable for a main culture is selected from the plurality of enrichment cultures; producing a main culture that contains betaine under the photoautotrophic condition and a salt concentration of 10 wt. % or more; and separating betaine. In the main culture, the algae containing betaine are cultured while the mixed gas containing sulfurous acid gas and carbon dioxide is blown to a culture solution of the algae.

Provided is a medical retractor capable of ensuring visibility in a field of operation and in the periphery of the field of operation while realizing the reduction of weight of the retractor compared to a conventional steel-made retractor. A medical retractor includes: a grip portion; and a resin functional portion made of a transparent resin and extending from the grip portion. The resin functional portion has: a trunk portion which has a proximal end thereof connected to the grip portion; and a hook-shaped portion extending in a hook shape from a distal end of the trunk portion. The resin functional portion is configured to allow the viewing of an affected part which opposedly faces a back surface of the resin functional portion from a front surface side in a see-through manner.

The present invention provides a thin-film capacitor device having a charging circuit and a discharge circuit and capable of stably producing a constant voltage during discharging a thin-film capacitor by an inexpensive configuration. The thin-film capacitor device is characterized by a hybrid type for temporarily storing charge upon receiving DC current from the thin-film capacitor while the voltage becomes lowering, and for supplying DC current in a state of a DC/DC inverter having a base voltage remaining so that a discharge effect continues until the amount of storage in the thin-film capacitor completely runs out.


Disclosed is a composition for supplying dietary fiber to food and drink and/or for improving quality of food and drink, which includes a partially hydrolyzed substance of glucomannan. This partially hydrolyzed substance of glucomannan has a viscosity in a 1% aqueous solution which is in a range of 1,000 to 10,000 mPas and a weight average molecular weight which is in a range of 100,000 to 800,000. Because an aqueous solution thereof is lowly viscous, not only the composition can be added to food and drink, in a comparatively high concentration, but also upon adding the composition to an emulsified food such as an ice cream, even by heating, a shape of the food before heating can be retained.

When fitting a male connector portion and a female connector portion of a connector together to achieve electric conduction, or when separating the connector portions, if a voltage is being applied to an internal conductive cable of the connector, there is a risk of electric leakage if placed in a conductive liquid, and there is also a risk of catching fire due to an electric discharge if placed in a flammable gas. In the present invention, a male connector and/or a female connector portion having a sealed chamber are utilized, and connection and separation of a first electrode and a facing second electrode are performed inside the sealed chamber. That is, the female connector portion is provided with: a casing; seal sections for sealing off the interior of the casing; first and second electrodes provided inside the casing; and an electrode connection control section that separates the first and second electrodes from each other in a state in which the female connector portion is not fitted to the male connector portion, and connects the electrodes together in a fitted state.

A sustained release solid dosage preparation is provided comprising an active ingredient admixed with an excipient. At least part of the excipient consists of glucomannan microparticles having an average particle size less than 50m. The glucomannan microparticles forms, when absorbing water, a hydrogel matrix for the active ingredient capable releasing the active ingredient almost entirely up about 6 hours.

There is provided an architectural structure (5) including: a building body (2) which has a pair of walls (14) facing each other; and a building roof (50) which covers an upper section of the building body (2), in which the building roof (50) includes a roof supporting section (60) which has a lower chord member (62) that is formed of steel and spans the pair of walls (14) facing each other, an upper chord member (63) that is formed of steel and is arched to connect both end sides of the lower chord member (62), and an connection post (64) that is formed of steel and connects the lower chord member (62) and the upper chord member (63), and that is arranged on the building body (2), and an external roof which is formed of reinforced concrete , and which is inclined upward from the pair of walls (14) sides to the center side between the pair of walls (14) and is arranged so as to cover the roof supporting section(60). Hence, the architectural structure 5 has increased safety and the load on a structural member is limited.


To provide a water power conversion device which enables low cost, no pollution, and large-capacity power generation by solving the disadvantages of a lift type using a drag type waterwheel. [Solution] The present invention is an underwater waterwheel, the waterwheel being a rotary waterwheel that rotates about a rotating shaft or an endless chain waterwheel in which a continuous belt is stretched between a pair of escape wheels, and the present invention is characterized in that a bottomless cup is pivotally fitted by a pivot on an outer wheel of the rotary waterwheel or on the continuous belt of the endless chain waterwheel so as to be able to stand up or lie down, in the state where the outer wheel or the continuous belt advances in the same direction as the direction of flowing water, the bottomless cup goes into a standing state, the bottom of the cup is closed by a bottom plate provided on the outer wheel or the continuous belt, and the cup functions as a water-receiving cup having high flowing water resistance, in the state where the outer wheel or the continuous belt advances in the reverse direction to the direction of flowing water, the bottomless cup goes into a lying down state, the bottom of the cup goes into an open state, thereby flowing water resistance becomes lower, the bottomless cup rotates or circulates by the resistance difference between both the states, and by providing a water-blocking plate on the upstream side on which the bottomless cup goes into the lying down state, a stagnant water area is formed in the reverse advance path to cause centrifugal force to act on the bottomless cup and turn the bottomless cup from the lying down state to the standing state.
