摘要： There is a need for improving switching regulator characteristics and providing a stable power supply controller. The power supply controller uses a battery and either or both functions of stepping up and stepping down a battery voltage. The power supply controller includes a means that prevents a ripple voltage from occurring by stopping the up conversion function for a switching operation in connection with a battery during a predetermined period without changing conditions for a conventional switching device or smoothing circuit and fast stabilizes a primary voltage using only the down conversion function.

摘要： There is proposed a control unit for an internal combustion engine, which comprises a boost circuit, a switching element, a current detecting resistor and a controller and is designed to be actuated such that the boost circuit is used to boost a power source voltage to create a boosted voltage and the controller is used to control the switching element so as to enable the boosted voltage to flow to the injector solenoid coil. This control unit is designed such that, when the boost circuit goes out of order, the injector solenoid coil is excited by making use of the power source voltage without using the boosted voltage and without creating a peak current to thereby generate a first holding current required for opening the injector and a second holding current required for retaining the opened state of the injector, the second holding current being lower in intensity than the first holding current.

摘要： According to the present invention, the operation of a diagnostic circuit within a load drive circuit, which has been built into an electronic control device, is checked without modifying the electronic control device or the like. The load drive circuit, which drives a load such as a solenoid using a DC power supply as a power supply, includes a drive circuit and a diagnostic circuit which is independently provided within the drive circuit. Upon input of a drive-stop signal from a control circuit that controls the drive circuit, the operation of at least the drive circuit stops, so that whether the diagnostic circuit, which diagnoses the condition of the load, is normally operating or not is checked in a condition in which the load drive circuit has been built into the electronic control device.

摘要： The present invention provides a magnetic recording and reproducing unit of a helical scan type having a slow speed tape running mode in which the speed of running a magnetic tape is slower than that of a standard running mode. The magnetic recording and reproducing unit of the present invention has a pair of azimuth heads of mutually different azimuthal angles which are mutually adjacently disposed on the outer periphery of a rotating cylinder and another pair of azimuth heads of mutually different azimuthal angles which are mutually adjacently disposed at positions symmetrical with the first pair of azimuth heads with respect to a rotating center of the rotating cylinder. Each pair of the two pairs of azimuth heads alternately traces tracks recorded with image signals on a magnetic tape to reproduce the recorded image signals. Further, the magnetic recording and reproducing unit of the present invention has a control head for reproducing from the magnetic tape a control signal which is synchronous with a header position of the recorded tracks, a traced azimuth predicting signal generating unit for generating a predetermined azimuth change over signal in response to the control signal, and a switching unit for selecting one of reproduced image signals from the pair of azimuth heads according to the change over signal in the slow speed running mode.
