Title: Lamp regulator
Inventor: SEKINE SHINJI
IPC: H05B39/09
Filed: 1990-08-31
Abstract: PURPOSE:To certainly stop a circuit operation in the case of abnormal energization so as to prevent any erroneous operation of a timer circuit by connecting, to the timer circuit, a capacitor arranged in parallel to a lamp so as to count a lighting time of the lamp. CONSTITUTION:In a MOSFET of a switching device 4, an output pulse signal of a pulse control circuit 5 is input into a gate, a DC power source output of a DC power source circuit 3 is input into a drain, and a high frequency rectangular wave voltage is generated by a gate input pulse signal, to be supplied to a lamp 6, thereby lighting the lamp 6. A timer circuit 13 is apparently converted into a DC voltage by a capacitor 11. A photocoupler 10 emits light when a voltage becomes higher than that of a Zener diode 8. With the light emission of the photocoupler 10, the timer circuit 13 on a secondary side starts to count a lighting time of the lamp 6. When the lighting time reaches a predetermined value, a circuit switch 2 is opened so as to stop a circuit operation of the lamp lighting. Therefore, the circuit operation can be automatically stopped with certainty after the lighting of the lamp for a predetermined period.

Title: Correcting system of shading
Inventor: MAEJIMA KATSUYOSHI
IPC: H04N1/04
Filed: 1983-12-09
Abstract: PURPOSE:To remove noises generated at the formation of correcting data effectively and to obtain an excellent picture signal by connecting a memory for storing a signal obtained by reading out a reference surface and arithmetically processing the signal stored in the memory to form a corrected signal. CONSTITUTION:Prior to scanning, a reference white plate to be a reference is read out and the read-out picture is A/D converted in each line of main scanning and stored in an RAM52. The stored signal is read out synchronously with the real picture read out from the original and applied to an address signal line of an ROM54. A signal obtained by matching the timing of an input picture signal through a type flip-flop 50 is inputted to the ROM54 and the ROM54 executes the arithmetic processing for the correction of shading and stores the processed result. When the arithmetic result for the shading correction which is stored in the ROM54 is read out, a signal from which shading caused by the uneven light emitting of a fluorescent lamp as an illuminating light source, uneven density due to the dirt or the like of a reflecting mirror and the uneven distribution of luminance intensity of an optical lens is removed is obtained.

Filed: 1986-09-30
Abstract: PURPOSE:To realize a uniform proximity state by absorbing variance due to a mechanical error in the energizing of a transfer conveyor unit elastically in case of forming a proximity part between a transfer conveyor belt and an electrostatic latent image carrier. CONSTITUTION:A pushing-up spring 186 applies the pushing-up force of the transfer conveyor unit 48 to a pushing-up plate (2)190. The pushing-up force balances with the weight of the transfer conveyor unit 48, so the transfer conveyor unit 48 can not be pushed up only with the pushing-up force of the pushing-up spring 186, but the pushing-up force by the pushing-up lever 184 can be reduced. Further, the stroke required to pushing the transfer conveyor unit 48 up to the pushing-up position is made sufficiently large. The generated stroke difference is absorbed by the pushing-up plate (1)188 which is an elastic body and the transfer conveyor unit 48 is securely pushed up to the pushing-up position all the time.

Filed: 1985-10-18
Abstract: PURPOSE:To prevent the occurrence of a jamming by setting a surface electric resistance ratio on the surface of a threading guide at a specified value or above and also setting a peeling charge quantity on the back surface of a tape at a specified absolute value or above under a specified condition. CONSTITUTION:In a video cassette 1, the peeling charge quantity between the back surface of a tape 3 and the magnetic tape side surface of a threading guide 5 is set at the absolute value of 3.2X10<-10> coulombs or above under the condition of the temperature of 25 deg.C and the humidity of 30% RH. Therefore, an attracting and attaching state between the magnetic tape 3 and the threading guide 5 can be generated by electrostatically charging them. Furthermore, since the surface electric resistance on the magnetic tape side surface of the threading guide 5 is assigned as, at least, 1X10<14>OMEGA or above, electric charge in charging is easily prevented from being lost, thereby the attracting and attaching state being maintained. Therefore, as much sagging as enough to generate the jamming of the tape can be prevented from occurring and the jamming in the loading/unloading of the video cassette to a VTR can be prevented from occurring.
