  • Patent number: 9773878
    Abstract: A semiconductor device includes a first main electrode terminal and second main electrode terminal disposed on the principal surface of a semiconductor substrate so as to be spaced from one another, an insulating film formed on the principal surface of the semiconductor substrate, and a thin film resistance layer. One end side of the thin film resistance layer is connected to the first main electrode terminal and the other end side of the thin film resistance layer is connected to the second main electrode terminal, the thin film resistance layer being spirally formed on the insulating film in such a way as to surround the first main electrode terminal. The thin film resistance layer extends while oscillating in a thickness direction of the semiconductor substrate.

  • Patent number: 9762048
    Abstract: A first sense resistor is connected between a fourth terminal of a power source potential of a high-potential region and a first terminal of a ground potential. A second sense resistor is connected between a third terminal of a reference potential of the high-potential region and the first terminal. A comparator is disposed in a low-potential region and uses the ground potential as a reference potential for operation. The comparator compares a voltage between an intermediate potential point of the first sense resistor and an intermediate potential point of the second sense resistor with a predetermined reference voltage. The output of the comparator is input through a control circuit and a level shift circuit to a high-side drive circuit driving an upper-arm IGBT. The output of the comparator is input to a driver circuit driving a lower-arm IGBT.

  • Patent number: 9113791
    Abstract: Measured blood pressure data is stored in a memory in association with information related to a measurement time. In response to manipulation of a manipulation portion (memory recall switch), blood pressure data associated with the measurement time within a prescribed time period (for example, 10 minutes) from the measurement time of reference blood pressure data, among the blood pressure data stored in the memory, is retrieved as specific data. Then, an average value is calculated based on the specific data, and the calculated average value is displayed as an evaluation index.

  • Patent number: 9002718
    Abstract: When the present time of a clock circuit is a medication time recorded in advance in a SD card, a notice that the medication time has come is given by a voice output portion or the like. Presence/absence of a medicine package in each block of a medicine package case is sensed by a medicine package sensor. The time point and the presence/absence of the medicine package are recorded in the SD card. A notice corresponding to the presence/absence is output. At a time except for the medication time, taking-out of the case, opening/closing of the cover, taking-out and return of the medicine package are recorded in the SD card based on detection signals from the medicine package sensor, medicine package case sensor, and case cover opening/closing sensor. A notice corresponding to the sensed situation is output.
