Abstract: [Problems] To provide an antibacterial agent, particularly a novel polypeptide compound having an antifungal action. [Means for Solution] As a result of an extensive study on a novel antifungal agent, the inventors have found that an excellent anti-deep-fungal activity is exhibited by introducing a cyclohexylmethylamino group or a piperidylmethylamino group as a partial structure of a natural polypeptide compound, and completed the present invention. The compound of the present invention has an excellent antibacterial activity and is therefore useful as an agent for preventing or treating various fungal infections.

Abstract: A jet generating device includes a vibrating member which vibrates gas, a driving unit which drives the vibrating member, and a housing which has a first opening and a first chamber connected to the first opening and containing the gas. The housing supports the vibrating member, and is such that, of sounds generated as a result of vibrating the vibrating member, the sound having a maximum noise level has a predetermined frequency. In addition, the housing discharges the gas as pulsating gas through the first opening as a result of driving the vibrating member.

Abstract: There are provided a cooling device and a heat sink that can effectively radiate heat generated by a heat source while reducing the volume of discharged gas to avoid noise, and an electronic apparatus in which the cooling device and the heat sink are mounted. A heat sink 3 includes cutouts 24a and 24b through which air serving as gas can be taken in from the outside and which are provided on a side where air discharged from first and second nozzles 6 and 7 serving as openings of a jet generating mechanism 2 is received. Therefore, the pressure near the cutouts is decreased by air flow discharged from the first and second nozzles 6 and 7, and outside air is taken in through the cutouts 24a and 24b. Consequently, more gas than gas discharged from the first and second nozzles 6 and 7 is discharged from an outlet of the heat sink. This can minimize the volume of jetted gas to avoid noise, and effectively radiate heat generated by a heat source.

Abstract: This invention provides a cooler having an excellent cooling performance, which is capable of being downsized and low-profiled, an electronic apparatus and a method for fabricating the cooler. The cooler (1) comprises lower board member (10) and upper complex board members. The lower board member (10) is made from plastic material and has a cavity portion (11) for allowing water or vapor to be circulated therein. The upper complex board members comprise board member (20) for a condenser part, upper board member (30), and board member (40) for a wick part. The board members (20) and (40) for the condenser part and the wick part, respectively, are made from metallic material having higher thermal conductivity such as copper and nickel. Each of the members has a groove for allowing them to be served as the condenser and the wick.

Abstract: An optical switching element having a simple configuration and high response and capable of performing gradation display by area gradation is provided. In a state where a light extracting portion is in contact with an upper substrate, light enters the light extracting portion from the upper substrate, emits from the back face of the light extracting portion, is passed through a lower substrate, and becomes transmission light. In a state where the light extracting portion is attracted by the lower substrate side, the incident light is totally reflected by a total reflection face, and total reflection light emits from a V-shaped groove. The incident light can be switched in two directions and obtained as the transmission light and the total reflection light.

Abstract: A heat transport device includes an evaporator, a condenser, and a vapor channel and a plurality of liquid channels that connect the evaporator and the condenser. The evaporator generates a capillary force to circulate working fluid. This structure prevents the performance deterioration and malfunction due to the entry of vapor-phase working fluid into the liquid channels. Since the cross-sectional areas of the liquid channels gradually decrease from the condenser toward the evaporator, the capillary force at the liquid channels can be increased, and vapor-phase working fluid is prevented from entering the liquid channels. Wicks and the portions of the liquid channels adjacent thereto are filled with liquid-phase working fluid even after dryout occurs, stable operation is achieved.
