Title: Image pickup device
Inventor: HIRAMOTO MASAO
IPC: H04N5/225
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To eliminate a foreign material adhered to a protective member protecting a reflecting mirror in the case of photographing an image formed by light reflected in the reflecting mirror. SOLUTION: In this image pickup device 100, an image pickup section 13 forms an image from a light which is incident externally and is reflected at the mirror surface of a reflecting mirror, and an arithmetic control section 32 reads a 1st image. A rotation control section 34 supplies a current for 1 second to a motor 15, which turns a support by 5 degrees. The arithmetic control section 32 reads a 2nd image. The arithmetic control section 32 subtracts the 2nd image from the 1st image for each pixel to obtain a result of binary arithmetic operation. If the arithmetic control section 32 judges that the result of binary arithmetic operation includes a value '1', an electromagnetic valve 22 is opened for 5 seconds, and compressed air supplied from a compression bomb is jetted from the jet port of a nozzle for that time.

Abstract: PURPOSE: To prevent erroneous diagnosis by percolation by prohibiting fault diagnosis when the engine temperature becomes higher than the first set temperature, and allowing fault diagnosis to be started when the engine temperature becomes less than the second set temperature (<the first set temperature).  
     CONSTITUTION: An internal combustion engine is equiped with an air-fuel ratio control device performing the feed-back control of the air-fuel ratio based on the output from an oxygen concentration detector 13 provided for an exhaust passage.

Filed: 1979-11-29
Abstract: PURPOSE:To reduce useless power consumption during the lightly loaded and thus realize low power consumption, by detecting magnitude of the load of a step motor through the integration of a drive current waveform and then controlling the drive pulse duration. CONSTITUTION:The pulse current of the fixed duration is applied to the drive coil 62 from the dividing circuit 28 via drivers 56 and 58, and thus the step motor turns. This drive current is converted into the voltage by the operational amplifier 66 in the current integral network 64 and via the drivers 56 and 58 each. Thus an integration is given to the integral network consisting of the capacitor 72 and the resistance 70 connected to the FF72 and 74, etc. which receive the ON/OFF control in accordance with the drive of the coil 62. Then the voltage is applied to the opertional amplifier 88 to which the reference voltage corresponding to the integral voltage during the light load of the control circuit 86. And the FF94 is set by the amplifier 88 when the load of the step motor increases, and the AND gates 32 and 34 are controlled via the OR circuit 98. Thus the broad division output supplied from the circuit 28 is turned into the drive pulse. As a result, the useless power consumption is reduced during the lightly loaded.
