Title: Method for stabilizing surface potential of electrophotographic photosensitive body
Inventor: NOGUCHI TERUHIKO
IPC: G03G21/08
Filed: 1987-07-21
Abstract: PURPOSE:To stabilize potential in uniform electrification, by changing a static eliminating light quantity fitting to the fatigue recovery characteristic of a photosensitive body due to a pause time and a consecutive operation. CONSTITUTION:To a microcomputer 20 which controls the static elimination lamp 27 of a photosensitive drum, a ROM21 in which a control program and a duty factor table are stored, counters A-C, and a RAM22 on which a flag and a timer are set are connected. And since the light fatigue on the surface of the photosensitive body is increased gradually according to a consecutive operation while it is performed, the static eliminating light quantity before the process of the uniform electrification is decreased gradually. Also, when the next operation is started after pause, the quantity is set so as to be increased corresponding to the length of the pause time, and also, increasing speed is set at the speed at which the static eliminating light quantity at the time of starting the preceding operation can be attained rapidly. In such a way, it is possible to maintain the potential on the surface of the photosensitive body constant.

Inventor: MITSUI HISAYASU
IPC: G01N21/25
Filed: 1984-08-31
Abstract: PURPOSE:To make it possible to easily diagnose the deterioration state of an insulating material in a non-destructive state, by collimating the interrelation of the change in the color of the insulating material being a reference material and the change in the insulating characteristic thereof with the value obtained by quantifying the luminosity and chromaticity of the color of an insulating material to be diagnosed. CONSTITUTION:At first, an insulating material being a reference material, for example, a polyester laminate board is forcibly deteriorated under heating and the color thereof at this time is measured to calculate luminosity L and chronmaticity showing a color phase and saturation while the wt. reduction ratio, breakdown voltage and tensile strength of a specimen are measured to fabricate a chart showing the interrelation of the luminosity L, the chromatty and each insulating characteristic. When the life breakdown voltage of the insulating material is set to 75% of the initial value, the luminosity L at this time is 60 and, thereof, if the luminosity L of the polyester laminate board to be diagnosed is 60 or more, the exhausion of life is judged to dischard said board. By this method, the deterioration state of the insulating material can be easily diagnosed in a non-destructive state.

Title: Automatic inspection method for magnification and focus of optical reading head
Inventor: TAKEDA KAZUHIRO
IPC: G02B7/28
Filed: 1980-12-25
Abstract: PURPOSE:To decide the accuracy of both the magnification and the focus of a line sensor, by reading the stripe mark which is slightly oblique to its teaveling direction and then processing the read signal. CONSTITUTION:An inspecting medium 9 having a width (w) of the white and black parts which is equal to the length (l) equivalent to a photoelectric element of a line sensor 8 is moved in the direction X to be read by the line sensor 8. Then the outputs of all bits are stored when the 1st bit is equal to the 2nd bit of the sensor 8. In this case, if coincidence is obtained between the width W of a stripe mark and the pitch (l) of the sensor 8, an output waveform (a) is obtained. And waveforms (b) and (b') are obtained if a shift of 1 bit is caused as a whole. Using this theory, the shift of magnification is known by the number of shifts of the output. The accuracy of focus is decided through the comparison between the maximum and minimum levels of the output of the sensor 8.

Title: Semiconductor memory device
Inventor: KOMURO TOSHIO
IPC: H01L21/8242
Filed: 1991-06-27
Abstract: PURPOSE:To prevent an amount of a sense amplifier input signal from being reduced due to a low-voltage operation of a semiconductor memory device. CONSTITUTION:In a stand-by state, bit lines D and DB and conductive layers SD and SDB which are opposite poles of a memory cell are connected to a fixed potential VR. When a sense amplifier SA is activated, the conductive layers SD and SDB are connected after a while although they are separated from the bit lines DB and D by transfer gates QT 1 and QT 2, respectively, and then the conductive layer SD becomes a same potential as the bit line DB and the conductive layer SDB becomes a same potential as the bit line D. When a selected word line is reset, the bit lines D and DB and the conductive layers SD and SDB return to the fixed potential VR, thus enabling an amount of accumulated electric charge of an accumulation capacitor CS to be increased. Therefore, the amount of accumulated electric charge can be increased by using a capacity of a memory itself, thus preventing an amount of input signal of the sense amplifier from being reduced due to a low-voltage operation.
