摘要： Induction heating apparatus using gate-controlled switching devices includes a zero crossing point detector for detecting the occurrence of each zero crossing point of high frequency energization current, and a timing circuit which provides timing action in response to the detected zero crossing point. The timing action is controlled by a power control circuit which detects the level of energy delivered to a load within a range from the inherent turn-off time of the gate-controlled switching devices to a desired value.

摘要： This gas shut-off system includes a flow rate sensor (2) for detecting a gas flow rate and a control unit having a miocrocomputer (6) which determines abnormal states such as gas leak when a predetermined flow rate continuously keeps over a predetermined time period and automatically closes a shut-off valve (4) in accordance with the determination. A battery (13) is employed as a power-source for the microcomputer (16) and the shut-off valve (4). In order that the consumption amount of the battery (13) is reduced as small as possible, the microcomputer has a standby function and is set to the standby condition except gas flow rate computation and so on until the shut-off valve (4) is opened after set to the shut-off condition. An indicating device for indicating various states of the system comprises a light emitting diode (19) which is single indicator, so that power consumption is reduced.

摘要： The present disclosure relates to a power supplier for a magnetron for use in electric appliances, such as a microwave oven. The power supplier of the present disclosure has a solid state frequency converter which changes commercial A.C. power to A.C. power at a high frequency, which A.C. power is increased in voltage in a step-up transformer and then fed to the magnetron. The power supplier further has a control system which stabilizes the power to be applied to the magnetron with respect to a preselected reference level and a power supplier protecting circuit for protecting the power supplier from an unexpected low voltage occurring in the commercial power source.
