Patent JP-H02300774-A (JP)
Title: Image forming device
Inventor: TANIGAWA KOICHI
IPC: G03G15/16
Filed: 1989-05-16
Abstract: PURPOSE:To obtain stable transfer performance regardless of an environmental change by connecting a bias power source to a transfer roller, and detecting the current of the power source and performing control so that the quantity of charges supplied from the transfer roller to a transfer material comes to constant. CONSTITUTION:Under low-temperature, low-humidity environment, the transfer roller 3 and transfer material P increase in impedance, and consequently the absolute values I+ and I- of both positive and negative current components decrease, so that the difference current DELTAI also decreases. For the purpose, a controller 8 increases the output voltage of the DC power source 6 and while the I+ is increased, I- is decreased so that the DELTAi equals DELTAI0. Under high- humidity environment, the impedance of the transfer material, etc., decreased, so the I+ is decreased and the I- is increased so that the DELTAI equals the difference current DELTAI0. Consequently, invariably stable transfer is performed under any environment.

Title: Urinal
Inventor: ONISHI HIROTO
IPC: E03D13/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To enable children to use a floor mounting or wall hooking urinal by forming a one-stage lower step on a drip receiving bowl fitted to the lower front of the urinal. SOLUTION: A urinal introduces wash water from the bottom of a drip receiving bowl 1 to a water distribution pipe at the back of a wall body via a trap 2 and a drain outlet 3. Then, the height H1 of the upper end of the bowl 1 and the aperture height H2 of the urinal are made as conventional and a one-stage lower step 5 is formed on the front of the bowl 1. Thereafter, the breadth of the step 5 is narrowed as much as possible within the range of such a size as allowing a child's use, thereby preventing a splash at the time of an adult's use. Furthermore, the step 5 is formed to protrude to the front ward when necessary, thereby allowing use by a child taking such a posture as striding over the step 5. A splash outside the urinal is thereby prevented. According to this construction, the urinal can be easily used by both an adjust and a child.

Title: Method for photographic-chemical immunoassay
Inventor: OKAZAKI MASAKI
IPC: G01N33/58
Filed: 1980-09-02
Abstract: PURPOSE:To easily label an antigen or an antibody by using mero-cyaine dye as a labeling agent having substituents including carboxyl group in the heterocyclic ring. CONSTITUTION:A merocyanine dye which has substituents including carboxyl group in the heterocclic ring as shown in the formula, is added to insulin and reacted to label the resulting product. The labeled antigen thus obtained is reacted immunochemically, and the product is dropped on the film painted with unexposed AgBrCl, then exposed to the light of wavelength which is absorbed by the dye. After developing this film, the blackening density on the film obtained by fixing, washing with water and drying according to the ordinary procedure, is measured by photographic densitometer. According to this process, an antigen or an antibody is easily labeled and the trace of them is detected.

Title: Positioning method by pulse motor
Inventor: KAMIO KENICHI
IPC: B23Q15/00
Filed: 1991-05-27
Abstract: PURPOSE:To surely and precisely stop an object at an original position without the occurrence of stop abnormality by permitting a sensor to detect the end part of a slit in a slit board and supplying the number of pulses, which is equivalent to the half of a slit width, to a pulse motor. CONSTITUTION:At the time of returning the shifted object transmitted to a prescribed position to the original position, it is returned to near the original position in steps A and B and the pulse motor is rotated by an angle equivalent to a remaining distance in a step C. when the sensor detects the slit end part 6a of the slit board 1, the number of pulses, which is equivalent to a size that is the half of the slit width, is transmitted to the pulse motor and the pulse motor is rotated so that a sensor position 7 becomes the center of the slit 6 of the slit board 1. Then, the slit board 1 is stopped at the center position of the slit as against the sensor. Thus, the shifted object can precisely be returned to the original position without stop abnormality even if the slit board 1 is rotation-shifted within a backlash range due to inertia and vibration force.

Abstract: PROBLEM TO BE SOLVED: To make the works for setting bending angle easier and bending process automated by installing the first angle setting method to set an angle as desired and the second setting method to set 90 degree bending, major works in bending, in accordance with the certain standards. SOLUTION: The first method 21 has a position setting disk 24 rotated ably attached to the supporting plate 26 on the top of the board on which the upper edge moves up and down. The outer diameter of the disk 24 becomes smaller as the disk rotates clockwise and the difference between the largest and smallest diameter is set as the stroke. As the disk 24 rotates and set the angle, the optical sensor 25 located on the lower edge detects the position of the limb 24a of the disk, and provide the data to the control unit 32 and the unit adjusts the stroke. The second bending angle setting method 22 has a position setting board 35 attached to the plate 5 which moves the upper edge up and down.  As the optical sensor 36 located on the lower edge support frame detects the position of the position setting board 35, the data is input in the control unit 32 and the upper edge stops downward movement at the point where 90 degree bending of the material is to be made.

Abstract: PROBLEM TO BE SOLVED: To make it possible to attain high speed operation with less source current consumption similar to an ordinary SRAM by providing a pair of capacitors instead of a high load resistor in a load circuit of a flip-flop in a memory cell. SOLUTION: A pair of capacitors C1, C2 charged to a voltage answering to the voltage of a power source line Vdd are provided in the load circuit of the flip-flops Q1, Q2 constituting the memory cell of the SRAM unnecessitating refresh for keeping storage contents instead of the high load circuit connected to the power source line Vdd. Then, the charge voltage of the capacitors C1, C2 is made within the range capable of keeping the circuit state of the on/off of the flip-flops Q1, Q2. Then, when the charge voltage of the load circuit capacitors C1, C2 just after refresh is made sufficiently large beforehand, an error doesn't occur even without applying frequent charging/ discharging unlike a usual DRAM of storing information in cell capacitors. Thus, a charge/discharge period is lengthened, and the current consumption accompanying the charge/discharge is reduced.
