    摘要： A semiconductor device includes: a semiconductor substrate having a first semiconductor layer and a second semiconductor layer formed on a first surface; a diode having a first electrode and a second electrode; a control pad; a control electrode electrically coupled with the control pad; and an insulation member. The first electrode is formed on a second surface of the first semiconductor layer. The second electrode is formed on the first surface. Current flows between the first electrode and the second electrode. The control pad is arranged on the first surface so that the pad inputs a control signal for controlling an injection amount of a carrier into the first semiconductor layer. The insulation member insulates between the control electrode and the second electrode and between the control electrode and the semiconductor substrate.

    摘要： A refrigerant compressor (100) includes: a sealed vessel (103); a compression mechanism (101) that sucks refrigerant, sucked in the sealed vessel (103), for compression; a motor (102) that drives the compression mechanism (101); a suction pipe (104) for sucking the refrigerant into the sealed vessel (103) when sucking the refrigerant; a cover (117a) arranged to face an outlet of the suction pipe (104), to force the refrigerant sucked through the suction pipe (104) to collide against the cover for gas-liquid separation, and to allow liquid refrigerant from the separation to drop on a coil (126) of the motor (102); and a suction passage (118) that introduces gas refrigerant from the gas-liquid separation, for which the refrigerant sucked through the suction pipe is forced to collide against the cover (117a), to an inlet of the compression chamber provided in the compression mechanism (101). Thus, a decrease in density of the refrigerant to be compressed, sucked into the sealed vessel (103), can be prevented to prevent a decrease in refrigeration capacity, and the temperature of the motor (102) can be lowered to improve a motor efficiency.

    摘要： When a semiconductor substrate of a semiconductor device is viewed from above, an isolation region, an IGBT region, and a diode region are all formed adjacent to each other. A deep region that is connected to a body region and an anode region is formed in the isolation region. A drift region is formed extending across the isolation region, the IGBT region, and the diode region, inside the semiconductor substrate. A collector region that extends across the isolation region, the IGBT region and the diode region, and a cathode region positioned in the diode region, are formed in a region exposed on a lower surface of the semiconductor substrate. A boundary between the collector region and the cathode region is in the diode region, in a cross-section that cuts across a boundary between the isolation region and the diode region, and divides the isolation region and the diode region. The collector region formed in the isolation region has a higher dopant impurity concentration than the collector region in the IGBT region.

    摘要： Methods for manufacturing a semiconductor substrate and a semiconductor device by which a high-performance semiconductor element can be formed are provided. A single crystal semiconductor substrate including an embrittlement layer and a base substrate are bonded to each other with an insulating layer interposed therebetween, and the single crystal semiconductor substrate is separated along the embrittlement layer by heat treatment to fix a single crystal semiconductor layer over the base substrate. Next, a plurality of regions of a monitor substrate are irradiated with laser light under conditions of different energy densities, and carbon concentration distribution and hydrogen concentration distribution in a depth direction of each region of the single crystal semiconductor layer which has been irradiated with the laser light is measured. Optimal irradiation intensity of laser light is irradiation intensity with which a local maximum of the carbon concentration and a shoulder peak of the hydrogen concentration are observed. A single crystal semiconductor layer is irradiated with optimal laser light at energy density detected by using the monitor substrate, whereby a semiconductor substrate is manufactured.

    摘要： A data transmission system using a human body as a signal transmission path includes a transmitter and a receiver. The transmitter uses a pair of electrodes which are held in close proximity to the skin of the human body. The transmitter transmits data to the receiver through the signal transmission path partly extending through the human body when a user carrying the transmitter touches a touch electrode of the receiver. The electrodes are integrated into a garment worn by the user in such a manner that the electrodes are kept in a closely facing relation to the skin of the user, thereby establishing the electrical path extending through the human body. With the integration of the two electrodes into the garment, the user wearing the garment as an everyday clothes or uniform can be easy and convenient to carry the transmitter for successful transmission of the data.

    摘要： Touch-responsive data transmission system for elongating transceiver battery life and assuring one-touch data transmission includes a first transceiver worn on user and a second transceiver connected to equipment utilizing first transceiver data. User contacts first transceiver signal and ground electrodes and touches a second transceiver touch electrode to establish a signal path through user. First transceiver includes a detector for detecting a start signal from the second transceiver signal electrode. Second transceiver includes a generator for generating the start signal upon touching the touch electrode. Receiving the start signal, circuit elements responsible for data transmission are battery-energized to start data transmission from first to second transceivers. Circuit elements responsible for transmitting data remain deenergized until user touches the second transceiver touch electrode to save energy during non-operation and prolong first transceiver battery life. By touching the touch electrode, automatic data transmission remains possible without requiring additional starting procedures.
