摘要:
A silicon on insulator (SOI) semiconductor device includes a wire connected to doped regions formed in an active layer of a SOI substrate. A ratio of the area of the wire to the doped region or a ratio of the area of contact holes formed on the wire to the doped region is limited to a predetermined value. When the ratio exceeds the predetermined value, a dummy doped region is added to prevent the device from being damaged during a plasma process.

The gate width of a field effect transistor is increased to a value greater than a size of an active region by forming an inclined portion of a gate electrode. As a result, the current driving capability of a field effect transistor is increased without degrading the integration density. The driving capability of the transistor can be further effectively increased by forming an expanded portion of the active region at a location corresponding to the inclined portion of the gate electrode thereby reducing the resistance of the diffusion layer.

A low-noise-block downconverter (LNB) for use with flat antennas receiving dual polarized electromagnetic waves includes a body case mounted to a rear side surface of the flat antenna, the body case having two wave guide input ports corresponding to wave guide apertures of the antenna and enclosing a selective device alternatively allowing either one of two outputs corresponding to two different type polarized electromagnetic waves received.

A control system for a four-wheel drive vehicle includes a center differential provided between a front shaft and a rear shaft. The control system also includes a device for restricting a differential between the front shaft and the rear shaft by operating the center differential to be in a locking condition and a controller for controlling the differential restricting device so that a differential restricting force is increased based on an increase in an engine output. The differential restricting force is decreased based on an increase in a vehicle body speed.

A control system for a four-wheel drive vehicle includes a first differential provided between a front shaft and a rear shaft and a second differential provided between a right wheel and a left wheel. The control system comprises a first device provided in the first differential for restricting a differential between the front shaft and the rear shaft, a second device provided in the second differential for restricting a differential between the right wheel and the left wheel, and a device for controlling the restricting operations carried out by the first device and the second device. The controlling device includes a device for controlling operational timings in the first device and the second device so that the timing when the first device maintains the first differential in locking condition is different from the timing when the second device maintains the second differential in locking condition.
摘要:
A frozen food is thawed by irradiating the frozen food with far infrared rays while supplying cold air to the frozen food to maintain the surface temperature thereof at a level not higher than 10.degree. C. Prior to the far infrared ray irradiation, the frozen food may be irradiated with a microwave. Thus, the frozen food can be uniformly thawed while maintaining freshness without degradation of the taste and favor thereof.
