Title: Light measuring device
IPC: G01J1/02
Filed: 1992-04-02
Abstract: PURPOSE:To reproduce an excellent, small-sized, light-weight, and long-life detecting position by arranging a light receiving element, and providing a matrix-driven light gate element on the front face of the light receiving element. CONSTITUTION:A matrix-driven light gate element 7 is laminated to be bonded on the light receiving face 6 of a light receiving element 5. As the element 7, a liquid crystal shutter panel, on one face of which vertical transparence electrodes are formed, and on the other face of which lateral transparence electrodes are formed, is used. The amount of transmitted light can be controlled by controlling voltage applied between the transparence electrodes on both the faces. The transparence electrodes on both the faces of the element 7 are selectively matrix-driven in a state where a measuring light is shined into the element 7, to allow the light to pass through only the position of intersection of the driven electrodes, and to shut off the light at the other position. Thus, output current of the element 5 at each position is measured while the positions of the points through which the light is passed, are moved in order, and thus 20 intensity distribution of the light is determined. The need for mechanical elements is eliminated and thus the device can, be made small-sized and light-weight, etc. The detecting position of the light can be electrically moved by matrix-driving, and can be reproduced with high accuracy.

Filed: 1992-04-02
Abstract: PURPOSE:To prevent the transfer of ink to the rear of other material to be recorded even when and number of materials to be recorded overlap each other by perforing no next recording until the ink transferred to the material to be recorded is dried. CONSTITUTION:A control part 2 transmits output data to an output part 6 and informs the completion of transmission to a wt. control part 10.

Title: Manufacture of voice coil
Inventor: YAMAZAKI YUUZOU
IPC: H01F5/02
Filed: 1983-05-11
Abstract: PURPOSE:To prevent the variance of heat resistant bonding strength of a voice coil by previously applying a heat sensitive paint to one surface of a winding for voice coil and discriminating the thermal hostory the voice coil has received so far through the change in color of the paint. CONSTITUTION:A thermosetting resin adhesive material which is activated in terms of adhesive capacity and indicates an adhesiveness when a solvent is mixed with the material is applied to one surface of a thin leaf-like base material under a half-hardened state and is baked. The other surface of the base material, a heat sensitive paint which changes in color at the hardening temperature of the thermosetting resin adhesive material is coated and dried. Then a winding material for making voice coil is formed by cylindrically forming the thin leaf-like base material with the surface, to which the thermosetting resin adhesive material is applied, at the outside. Thereafter, a self-melting and adhering enameled wire which is activated in terms of the adhesive capacity and indicates an adhesiveness when a solvent is applied, is wound around the cylindrical base material with the solvent being applied. After the enameled wire is wound, the winding material is heated and dried. In this case, the change in hue of the surface, to which the heat sensitive paint is applied, of the winding material for voice coil correctly indicates the thermal history in accordance with the quantity of heat received by the voice coil. Therefore, the change in color can be used as an index for controlling heat in the course of the heat treatment.

Filed: 1981-05-29
Abstract: PURPOSE:To stabilize transfer and separation current, by inserting a voltage dividing resistor between a casing of a charger for separation to separate a copy paper from a photoreceptor drum and a corona wire. CONSTITUTION:A series circuit consisting of resistors R1 and R2 is connected between a corona wire 12 connected to a constant current high voltage generator and ground, and to a voltage dividing point P, a casing 12 of a corona charger for separation 10 is connected.
