IPC: G01R15/18
Filed: 1984-09-21
Abstract: PURPOSE:To eliminate an influence of an induced voltage to a signal source to be detected, without spoiling a response, by offsetting waveform distortion generated in a circuit to be detected, with respect to an input signal source by a current generating means. CONSTITUTION:A titled detector is provided with a transformer consisting of a magnetic core Cr3 and windings ND1, ND2, and the winding ND1 and the winding ND2 are inserted so as to be in series to a load resistance RP, and in parallel to a power source to be detected EC between A and B, respectively. In this state, in a period in which a magnetic core Cr1 is unsaturated, and a magnetic core Cr2 is unsaturated, no voltage is generated in the windings ND1, ND2 of the magnetic core Cr3 because diodes D21, D22 are in a conductive state. Subsequently, in a period in which the magnetic core Cr1 is unsaturated, and Cr2 is saturated, an output current iL2 flows along a closed circuit of an AC power source Ea   the diode D21   the resistance RP  the winding ND1   a winding NL2   a diode D12   Ea. Accordingly, when a transformer circuit is inserted in parallel to the power source EC, a strain current which follows an input winding induced voltage does not flow. Accordingly, such problems as heating by the strain current and a damage to the power source EC, etc. are eliminated.

Title: Exposure lighting device
Inventor: SUGIYAMA TSUKASA
IPC: G03G15/04
Filed: 1989-07-31
Abstract: PURPOSE:To enable exposure lighting by remaining lamps even if one lamp has a disconnection by outputting information of an original size which can be lighted for exposure with the disconnection disconnection detection information. CONSTITUTION:In a normal case, a CPU 13 selects a lamp 1 to be turned on corresponding to original size. For, for example, an intermediate-size original, a signal which turns on lamps NO.1 - NO.3 and turns off a lamp NO.4 is sent to an automatic voltage adjusting device AVR 11. If, for example, the lamp NO.4 has a disconnection, the signal from a means 10 which detects a current becomes 0 and the CPU 13 judges the size of a original which can be irradiated with lamp by the signal from the remaining means 10 and the original is irradiated by th lamp through the AVR 11. Consequently, even if wire breaking occurs to any lamp, the original of size within the range of exposure by the remaining lamps can be irradiated for exposure.
