Title: Voltage monitoring circuit
Inventor: IKEDA AKIHIRO
IPC: H03F3/00
Filed: 1986-10-30
Abstract: PURPOSE:To enable accurate voltage measurement between an output terminal of a DC operational amplifier and grounding on the power source side, by subtracting a potential difference between grounding from a potential to be measured on the load side to perform conversion. CONSTITUTION:A potential difference Vd generated from a load current flowing through a resistance 4 between a power source side ground 8 and a load side ground 9 is applied to a negative input side of a DC operational amplifier 7. The sum V1 of a voltage V to be measured on the side of a load 2 and the potential difference Vd is applied to a positive input side of the DC operational amplifier 7 and an output voltage V0 is given by V0=(1+R4/R3)R2Vi/(R1+ R2)-R4X Vd/R3. Here, by selecting the values of R1, R2, R3 and R4 to meet R2/R1=R4/R3= constant, the voltage V0 outputted at a terminal 5 is proportional to the voltage V to be measured. This enables measurement of the voltage V to be measured between the terminal 5 and a grounding terminal 6 on the power source side.

Title: Image control device
Inventor: KATO HITOTSUGU
IPC: G09G5/377
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent the whole of an image control device from decreasing in a processing speed even if multiple backgrounds exist, not by displaying both backgrounds overlapped but by displaying them split with the boundaries of the display positions. SOLUTION: On a background plane BGB, for example, an area of 42 cells ×28 cells toward the center in one block consisting of 64 cells × 32 cells is defined as a displayable cell. Therefore, by rewriting display position coordinates (X, Y) of the register which shows an original point in the display area, relative scroll of the display screen on the background plane BGB becomes possible. And, when the display plane scrolls the area where background side BGA and background side BGB overlap, only the background plane BGB is displayed by split display. Further, the area which comes off both of the background planes BGA and BGB is included in the display screen, the area becomes a backdrop plane and is displayed transparently (monochrome).

Title: Camera and electronic flash
Inventor: YASUI EIHIKO
IPC: G03B15/03
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To eliminate a fear of getting an electric shock by discharging a main capacitor according to removal of external members, to perform a repair job or the like without anxiety. SOLUTION: At the time of repairing a camera, a loaded battery B is removed first. Following this, external members are removed, however, a removal detecting means 33 detects that the external members have been removed in a different state changed from that before the removal. A CPU 31 receives this state signal from the removal detecting means 33. The CPU is able to operate with an auxiliary power source 35 even though the battery is removed. This arrangement enables the CPU to operate a gate of a thyristor S, to make a xenon tube Xe emit light to discharge a main capacitor CM and a trigger capacitor CT. As the result, the voltages of the main capacitor CM and trigger capacitor CT drop. After that, since the battery is removed and a stroboscopic circuit is not recharged, there is no fear of getting an electric shock and this permits to safely perform a repair job.

IPC: G01D5/36
Filed: 1991-10-08
Abstract: PURPOSE:To remove a low frequency noise and a high frequency noise without including a reflected noise by removing a low frequency component from a receipt signal, and then conducting absolute value detection to smoothen the signal. CONSTITUTION:In a light receiving part 30, a receipt signal outputted from an amplifier 32 is passed through a high pass filter formed of a capacitor C and a resistance R to remove a low frequency noise, and a DC component is also removed so that its center is OV. The resulting signal is inputted to an absolute value detecting circuit 39 to conduct absolute value detection (full wave rectification) and then smoothened by a low pass filter 40.

Abstract: PROBLEM TO BE SOLVED: To treat raw material strongly coated a portion of sludge with asphaltene and to continuously recover a clarified oil lowered the content of sludge by treating an oil component containing sludge and water by using a screw type decanter. SOLUTION: A raw liquid slurry fed into rotating ball 8 is affected by a a centrifugal force, and the water component in the raw liquid, the sludge and an emulsion containing water, having heavier density, move outward against the radial direction, collects on an outer layer potion of the rotating ball 8, move in the direction of a slant part by a screw conveyer 6 and discharge from a heavy liquid outlet 4. In this case, because the water component, the sludge and the emulsion containing water can be not guided to the heavy liquid outlet 4 only with the screw conveyer, the height of a flash board 3 is adjusted and they are required to be discharged together with one portion of light oil (clarified oil).  Meanwhile, the clarified oil having lighter density moves inward against the radial direction, collects on an inner layer portion, going over the flash board 3 at a large diameter end side and discharges from a light oil outlet 9.
