摘要： The present invention realizes an injector drive circuit capable of providing high output power of a boost convertor while suppressing increases in size and cost thereof. An injector energizing circuit 200 includes an FET 2 which applies a high voltage 100a generated by a boost convertor 100 to an injection valve 20. The boost convertor 100 includes an input side capacitor 103, a boosting FET 105, a boost coil 104, a boost diode 106, and FETs 108 and 109 provided in association with a negative pole of an output side capacitor 107. During a period in which the high voltage 100a is applied to the injection valve 20, a gate signal 108a of the FET 108 is turned ON and a gate signal 109a of the FET 109 is turned OFF. Consequently, the boosting FET 105 performs a switching operation to turn OFF the gate signal 108a of the FET 108 and turn ON the gate signal 109a of the FET 109 during a period for charging into the output side capacitor 107. Thus, energy required for boosting can be reduced and an improvement in output is enabled.

摘要： An internal combustion engine controller comprises a booster coil connected to a battery and a booster capacitor. A switch element is connected to the booster coil to control the passage of current through the booster coil and an interruption of the current. The booster capacitor accumulates electrical energy generated with an inductance of the booster coil at the time of the interruption of the passage of the current. A booster control circuit carries out control in a constant boost switching cycle so as to pass the current through the booster coil and the switch element until the current reaches a preset switching stop threshold value and then interrupt the current to charge the energy generated with the inductance of the booster coil into the booster capacitor. The booster control circuit is configured to ensure a minimum time period for the booster capacitor-charging of the energy within the boost switching cycle.

摘要： A load driving and diagnosis system controls the feed and block of a load current flowing into an inductor such as a solenoid. The load driving and diagnosis system holds a counter-electromotive force, which is developed when the load current is blocked, at a voltage higher than a supply voltage so that the load current will decay for a short time. When an overcurrent condition is established in the load driving and diagnosis system because of a short circuit to a power supply, a malfunction of a circuit or destruction thereof may take place. In addition to a voltage holding means that holds a switching circuit output voltage at a predetermined voltage, a voltage holding means having a different predetermined voltage set therein is included. Moreover, a selection switch that switches the predetermined voltages according to a detected overcurrent condition is included.

摘要： A time lapse magnetic recording/reproduction apparatus for recording and reproducing picture signals while intermittently thinning them out in a frame unit is used for monitoring and burglar-proofing in plants, shops, banks, etc. Recording picture information is generated and added to one continuous picture signal obtained by sequentially switching the output of each video camera, and is then recorded. A speed multiple k for a normal tape travelling speed is optimally set by servo circuit on the basis of the recording picture information (the total number m of channels) detected from the reproduction picture signals reconstructed by double-azimuth four heads at the time of search reproduction, and a search reproduction picture throughout the full screen of a monitor television is obtained in full recording channels. At the same time, a write period into an image memory is controlled in accordance with the recording picture information (the total number m of detection channels) and a reproduction head signal level, and read controller then controls sequentially readout of the picture signals from image memory storing therein only specific channels.
