Title: Coordinate input device
Inventor: BANDO TOSHIRO
IPC: G06F3/045
Filed: 1986-06-17
Abstract: PURPOSE:To read coordinates with simple constitution by applying alternately a voltage between the opposite sides of the electrodes of four sides, and reading the coordinates based upon the voltage outputted to the second resistance layer at the time of contacting a pair of the resistance layer. CONSTITUTION:By turning off a switch Sy (equivalent to transistors 15 and 16) and turning on a switch Sx (equivalent to transistors 13 and 14), a voltage E is impressed between terminals X0 and X1. In such a condition, when a P point is pushed down, resistance layers 12a and 12b are brought into contact with each other and at a terminal S, a voltage Vx to partially pressure the voltage E at the P point appears. Since the voltage Vx is proportional to the distance in the X direction, the X coordinates of the P point can be known from the Vx. In the same way, by turning on the switch Sx and turning off the switch Sy, the Y coordinates of the P point can be known from a voltage Vy generating at the terminal S. A micro-computer 17 executes the above- mentioned switch changing-over and can be realized by making the output level of a port PA1 into L or H.

Title: Sublimation transfer recording material
Inventor: WATANABE HIDEO
IPC: B41M5/42
Filed: 1985-06-26
Abstract: PURPOSE:To ensure a high recording speed, a high recorded density and a low heating temperature of a thermal head, by using a base sheet also as an image-receiving sheet. CONSTITUTION:An ink layer 2 laminated on the base sheet 1 comprises a sublimable dye and a binder. A heat-resistant layer 3 laminated on the ink layer 2 is resistant to heat supplied from an external heat source, and has a certain degree of mechanical strength. When heat is applied to the layer 3 side in a dot form, the sublimable dye in the ink layer 2 at the dot is sublimed to dye the base sheet 1. When the sheet 1 is released from the ink layer 2, a record is left on the sheet 1. Thus, the base sheet is used also as an image- receiving sheet. The heat-resistant layer having favorable heat resistance and releasability is brought into contact with a thermal head. Accordingly, the recording material is not fused to the head, the head is not contaminated, and the recording speed is high.

Title: Liquid fuel feeding device
Inventor: YAMAMOTO YOSHIO
IPC: F23N1/00
Filed: 1977-11-18
Abstract: PURPOSE:To feed a constant amount of liquid fuel despite any change in temperature, by interposing in the pump circulation pass a thermal compensating conduit having a large change in passage resistance against a change in viscosity of liquid fuel. CONSTITUTION:Liquid fuel is naturally fed in a tank 3 through an oil pipe 2 from a separate tank 1. To keep the oil level constant in the tank 3, a valve 5 is controlled by a float 4, and most part of liquid fuel discharged to a branching chamber  7 returns to the tank 3 through a thermal compensating conduit 8 such as capillary tube. Part of liquid fuel in the chamber 7 goes to a burner through an oil feed pipe  9. Thus the utilization of change in passage resistance due to any change in temperature can compensate the change in oil feed sent to the burner.

Then, a switch 8 is turned on through the controller 12 to charge the storage battery 3-1 with an auxiliary charger 10. Likewise, a capacity testing and charging are automatically performed only for an abnormaly battery.

Title: Magnetic separation of labelled reagent for immunological bond measuring test
Inventor: DEBITSUDO ERU MOORISU
IPC: G01N33/553
Filed: 1988-06-08
Abstract: PURPOSE: To quickly separate and measure the binding species of a labeled reagent on a testing apparatus which does not require any cleaning process, etc., by performing the aliquot of a reaction mixture in the separation zone of the testing apparatus and, in addition, impressing a magnetic field upon the separation zone. CONSTITUTION: When the aliquot of a reaction mixture is performed in the separation zone of a testing apparatus and a magnetic field is impressed upon the separation zone, the free species of a labeled reagent is immobilized to the zone and the magnetically responsive reagent particles held by the reagent are held in the zone by magnetic forces and prevented from moving from the separation zone. Since a porous solid matrix used as a chromatography medium does not hinder the movement of the binding species of the labeled reagent to the matrix, the binding species is moved to a detection zone from the separation zone by a liquid testing medium. Then the detectable chemical group of the binding species in the detection zone is measured.  In addition, when the separation of the binding species and an immobilized free species from each other starts, a detectable signal is generated in the detection zone without performing any operating process, etc. Therefore, the binding species of the labeled reagent can be separated and detected in a short time under control.

IPC: G02B6/44
Filed: 1989-06-01
Abstract: PURPOSE:To provide the tension member which has the excellent controllability of the outside diameter and can arrange and house multi-fiber optical fibers on the outer periphery without impairing the suppleness by applying the 1st resin layer consisting of a thermosetting resin, in a laminated state, on the outer periphery of FRP. CONSTITUTION:The 1st resin layer consisting of the resin 2 selected from the resin group of the thermosetting resin and UV curing type resin and the 2nd resin layer consisting of the thermosetting resin 3 are applied, in the laminated state, on the outer periphery of the fiber reinforced plastic glass fiber (FRP) 1. The evaporation of the residual monomer from the FRP is, therefore, suppressed. The resin layer consisting of the thermosetting resin or UV curing type resin acts as a heat shielding layer and, therefore, the quantity of the residual monomer evaporating from the FRP is decreased. The excellent controllability of the outside diameter without impairing the suppleness is obtd. in this way and the arranging of the more optical fibers than heretofore on the outer periphery of the tension member is possible.

Title: Image processing device for copying machine
Inventor: KOGURE MASAAKI
IPC: G03G15/043
Filed: 1985-06-26
Abstract: PURPOSE:To perform a desired copy processing corresponding to an original image by controlling the ON timing of a light emitting element which should be turned on by an eraser on the basis of copy timing so that an image conforming to or approximating an image area is erased. CONSTITUTION:An original 10 is provided with a character area C and a drawing area P. When an image in a nearly elliptic area P is erased, an elliptic shape specifying key 17f is pressed to specify the area shape. Then, the coordinates of the center of the area P are inputted with a ten-key 14 on the basis of a scale. Then, constant X-directional length is inputted with the ten-key 14 and Y-directional length twice as large as it is inputted with the ten-key 14. Consequently, the substantial elliptic shape of the area P as an area to be erased is specified and calculated. Respective light emitting elements 9 of the eraser 3 are controlled by a controller not shown in the figure on the basis of the substantial elliptic shape. Thus, a desired copy processing corresponding to the original image is performed.
