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.

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. To display one pixel, in the light extracting portion and a plurality of other light extracting portions, the incident light is selectively taken by being switched between two directions of the transmission light and the total reflection light, thereby enabling the gradation display by area gradation to be performed.

A heat transport device has an evaporator and a condenser connected through a vapor phase channel and a liquid phase channel and has wicks of the condenser arranged symmetrically around an axis orthogonal to the direction of gravity. The flow of fluid in a liquid phase inside the wicks is not disrupted even when the heat transport device is tilted at any angle relative to the horizontal surface or the vertical surface.

Heat transport device and electronic apparatus

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.

To provide a small and lightweight optical switching element with a simple structure capable of fast response, and an optical switching apparatus employing the optical switching element. Optical extraction unit contacts an upper substrate with electrostatic attraction generated between a transparent electrode of the optical extraction unit and a transparent electrode of the upper substrate. In the case that light enters one V-shaped trench of the upper substrate vertically, the light enters the optical extraction unit of the upper substrate and is emitted from a back of the optical extraction unit (a tapered unit). Subsequently, the incident light P passes through a lower substrate and is converted into transmission light. With electrostatic attraction generated between a transparent electrode of the lower substrate and a transparent electrode of the optical extraction unit, the optical extraction unit is attracted to a lower substrate side. In this state, the incident light is caused the total reflection at a total reflection face. This total reflection light is emitted from the other V-shaped trench. The incident light can be switched in two ways: the transmission light and the total reflection light.
