  • Patent number: 8416591
    Abstract: Provided is a DC-DC converter including a soft start circuit capable of prolonging a soft start time without increasing a capacitance used in the soft start circuit. A soft start is implemented by gradually increasing a limiting level of an inductor current or a reference voltage. The soft start time is adjusted by varying a frequency of CLOCK signals supplied to switch circuits. The soft start time may be prolonged without increasing a chip size because the capacitance does not need to be increased to prolong the soft start time.

  • Patent number: 7967125
    Abstract: A deformed-coin detector accurately detecting a deformed coin without being affected by a variation in transporting speed of a coin. A coin transported along a coin transporting face comes into contact with detecting elements of coin-thickness detecting bodies, the detecting elements move by a distance corresponding to the dimension of the coin in its thickness direction and simultaneously, light shielding portions of the coin-thickness detecting bodies move. A light detecting portion detects a light shielding amount that varies due to movement of the light shielding portions. A coin denomination determining unit determines a denomination of the coin transported along the coin transporting face and reads a reference light-shielding amount pre-stored in a reference light shielding amount storing unit regarding the denomination.

  • Patent number: 7800433
    Abstract: Provided is a power supply switching circuit capable of efficiently supplying a desired voltage among a plurality of voltages to a load. In the case of a P-type semiconductor substrate, N-type MOS transistors are provided between a load and an AC adapter and between the load and a battery, and hence no parasitic diode exists between the load and the AC adapter or the battery, resulting in no current path due to the parasitic diode. Thus, when the AC adapter and the battery are connected to the power supply switching circuit, the N-type MOS transistor is turned off, whereby the current path between the battery and the load is cut off completely and the N-type MOS transistor is turned on. Accordingly, the battery cannot supply a voltage to the load while only the AC adapter can supply a voltage to the load.
