摘要:
An automobile air conditioner has a refrigeration cycle composed of a compressor, condenser, liquid tank, orifice means and an evaporator, as well as mechanical parts such as a radiator and radiator fan associated with the condenser and a blower combined with the evaporator. The compressor is operatively connected to the automobile engine through a connecting means so as to be driven by the engine selectively in accordance with the temperature in the passenger's compartment. According to the invention, the compressor is driven when the automobile is being braked, even if the temperature in the compartment is lower than a set temperature, to make an efficient use of the kinetic energy possessed by the mass of the automobile. The cold energy generated during braking is suitably stored and is released into the passenger's compartment as desired.

A compact heat pump system and a heat pump operation method employs an evaporator for recovering heat of an external heat source to a working medium supplied as liquid water from the exterior via a water feed channel, thereby evaporating the working medium, a compressor for compressing the working medium evaporated in the evaporator and increasing temperature of the evaporated working medium, and a driving unit for giving motive power to drive the compressor. The heat pump system further includes a supply channel for supplying, as a heat source, vapor of the working medium having a temperature increased by the compressor to an external heat-utilizing facility, and a return channel branched from the supply channel and introducing the working medium discharged from the compressor to the evaporator.

A first layer is formed on an underlying substrate having a surface layer made of semiconductor of a first conductivity type. The first layer is made of semiconductor having a resistance higher than that of the surface layer. A first impurity diffusion region of a second conductivity type is formed in a partial surface region of the first layer. The first impurity diffusion region does not reach the surface of the underlying substrate. A second impurity diffusion region of the first conductivity type is disposed in the first layer and spaced apart from the first impurity diffusion region. The second impurity diffusion region reaches the surface of the underlying substrate. A separation region is disposed between the first and second impurity diffusion regions. The separation region comprises a trench formed in the first layer and dielectric material disposed at least in a partial internal region of the trench.

摘要:
A thermal-type infrared radiation detector cell includes a diaphragm structural body that forms a gap of a predetermined width over a semiconductor substrate. The diaphragm structural body is capable of either providing metal wiring films that doubles as an infrared radiation reflector film or providing a high refractive index film having a thickness set to satisfy the expression d=&lgr;×{1/(4×n)}, where n is the refractive index of the high refractive index film, and &lgr; is the wavelengths of infrared rays. As a result, in the former option, no separate infrared radiation reflector film is required, whilst in the latter no separate infrared radiation absorption layer is required. This facilitates the manufacturing process and improves the sensitivity in infrared radiation detection.
