Abstract: A bipolar transistor includes a collector layer, a base layer, and an emitter layer that are formed in this order on a compound semiconductor substrate. The emitter layer is disposed inside an edge of the base layer in plan view. A base electrode is disposed on partial regions of the emitter layer and the base layer so as to extend from an inside of the emitter layer to an outside of the base layer in plan view. An insulating film is disposed between the base electrode and a portion of the base layer, with the portion not overlapping the emitter layer. An alloy layer extends from the base electrode through the emitter layer in a thickness direction and reaches the base layer. The alloy layer contains at least one element constituting the base electrode and elements constituting the emitter layer and the base layer.

Abstract: A thermoelectric generator includes a thermoelectric generation module, a power storage unit configured to store electric charge generated from the thermoelectric generation module, a switching unit configured to switch between supply and stop of discharge to a transceiver (transmission/reception unit) driven by discharge from the power storage unit, and a determination unit configured to determine stop of discharge from the power storage unit, in which the determination unit determines stop of discharge before completion of discharge from the power storage unit.

Abstract: A residual charge removal device includes: a power storage unit; a first switching unit that is connected to a target to which electric power is supplied from a power supply device, and operates to remove a residual charge of the target by electric power supplied from the power storage unit; and a second switching unit that operates to supply electric power from the power storage unit to the first switching unit when electric power supply to the target is stopped.

Abstract: A temperature control system which performs control of an object whose temperature is to be controlled as accurately as possible. The system comprises: a chiller located in a fluid circulating and supplying system, for cooling a thermal fluid returning from a vacuum chamber, a first flow control valve located in the fluid circulating and supplying system in a position between the chiller and the vacuum chamber, a bypass passage for splitting and supplying thermal fluid returning from the vacuum chamber to a position between the first flow control valve and the vacuum chamber, before it reaches the chiller, a second flow control valve located in the bypass passage, and a halogen lamp heater located in the fluid circulating and supplying system in a position between a confluence point of the bypass passage and the vacuum chamber, for adjusting the temperature of the thermal fluid passing therethrough to a set temperature.

Abstract: An ink-jet head comprising a plurality of sidewalls each imparting a pressure pulse to an ink pressurizing cell by means of shear mode deformation, and a front wall having a plurality of orifices. The ink in the ink pressurizing cells is ejected from the orifices. Each sidewall comprises a first wall section, a first electrode disposed thereon, an anisotropic adhesive disposed thereon, a second electrode disposed thereon, and a second wall section disposed thereon. Width of the first electrode is narrower than width of the first wall section, and the upper surface of the first wall section has first side areas which are not covered by the first electrode. Width of the second electrode is narrower than width of the second wall section, and the lower surface of the second wall section has second side areas which are not covered by the second electrode.

Abstract: A fuel control system for an engine has a fuel injector which injects fuel into an intake passage of the engine. An airflow meter detects the amount of intake air of the engine. A controller controls the amount of fuel to be injected from the fuel injection means on the basis of a dulled value by dulling a present value of the output of the airflow meter so that the preceding value of the output of the airflow meter is reflected in the dulled value in a predetermined proportion. The degree of reflection of the preceding value of the output of the airflow meter in the dulled value is reduced when the relation between the value of the output of the airflow meter and the dulled value is inverted.

Abstract: In an auto-focus, auto-exposure camera, a shutter operating member for controlling a consecutive photographing operation including focusing and exposing is provided with a program switch means for determining the timing of data recording so as to enable the data recording to be effected in the course of the photographing operation. By controlling the photographing operation by use of the program switch means, the data recording can effectively be performed without increasing the time required for the photographing operation.
