  • Patent number: 8102228
    Abstract: [PROBLEM] By simplifying a core securing structure of a reactor, miniaturization, lightweight, and low costs of the reactor are achieved. [SOLVING MEANS] The core securing member to secure a core 109 in a case 101 in the reactor wherein the core 109 and the coil 105 are housed in the case 101 is made up of a first spring portion S1 which gives momentum to a side face of the core 109 in a horizontal direction and a second spring portion S2 which gives momentum to an upper face of the core 109 in a vertical direction. Moreover, a stopper portion to restrict popping of the core from the case and the second spring portion are integrally formed with a notch being interposed between the stopper and the second spring portion so that the stopper portion covers part of an upper face of the core.

  • Patent number: 7120812
    Abstract: A power supply control apparatus for reducing the frequency of running a specific process in an electronic device when the device power turns on or off too soon after being turned off by monitoring the operating state of the power switch. When the power supply control apparatus detects an operation turning the power to the hybrid processing apparatus 1 off, the power supply control apparatus continues supplying power for as long as needed to complete a given shutdown process. However, if the power supply control apparatus 50 detects an operation turning the device power on again after the power supply stops but before reaching a predetermined reset voltage a reset and restart command is applied to the electronic device.
