Title: Transfer molding apparatus
Inventor: SASAKI KAZUHIKO
IPC: B29C45/02
Filed: 1982-10-01
Abstract: PURPOSE:To save molding material to be used by providing, to a runner, a plunger for pressing a runner which operates following a plunger for pressing a tablet with a certain delay time. CONSTITUTION:An IC14 is set in each cavity 9, and a metal mold 1 is formed by an upper punch 2 and a lower punch 3. A tablet 4 is accommodated in a pot 5 and is fused through the heating process. Thereafter, a plunger 7 is relatively moved downward and resin is pressurizingly supplied to each cavity 9 through a spool 6 and a runner 8. Until the plunger 7 reaches the lower dead point, a plunger 11 provided to the runner 8 is located at the lower dead point, and the runner 8 acquires the area which does not interfere high speed flow of resin. When the plunger 7 reaches the lower dead point, the plunger 11 starts to move upward. Thereby, the volume of runner 8 becomes narrow gradually, and the resin filled in the runner 8 is pressurizingly supplied into each cavity 9. The IC14 is perfectly molded by the resin and is sealed in non-hermetical manner.

Title: Fuel injection nozzle for internal combustion engine
Inventor: KURUTO ZAIFUERUTO
IPC: F02M45/08
Filed: 1980-12-05
Abstract: A fuel injection nozzle is proposed which opens toward the outside and functions with a valve needle and two springs, and further wherein a throttle restriction is effective after a first portion of the opening stroke, acting as a pre-stroke, and can be subsequently rendered ineffective. The two springs having a predetermined certain relationship to one another enable an abrupt increase in closing force after the pre-stroke. The first spring, embodied as a compression spring, acts in the closing direction; the second spring, having a smaller force than the first spring and acting counter to the closing direction, is rendered ineffective after the pre-stroke has been performed.

Title: Electrophotographic sensitive body
Inventor: TANAKA HISAMI
IPC: G03G5/05
Filed: 1985-08-05
Abstract: PURPOSE:To enhance surface lubricity and releasability, especially, cleanability, and repetition use durability by incorporating a comb type-silicone graft polymer and bisphenol terephthalate type polymer in the layer farthest apart from a substrate. CONSTITUTION:The layer farthest apart from the substrate, such as a nonphotosensitive surface layer, a photosensitive layer of single layer structure, an electrostatic charge generating layer or a charge transfer layer of laminate type photosensitive layers, contains the comb-type silicone graft polymer and the bisphenol terephthalate type polymer. Said silicone graft polymer is superior in compatibility with a coating fluid containing the bisphenol terephthalate polymer as the binder resin for forming the surface layer. The charge generating layer is formed by well dispersing a charge generating material together with the binder resin and a solvent, and coating the substrate with the coating fluid and drying it. The charge transfer layer is formed by dissolving a charge transfer material in a solvent together with a polycarbonate type resin and the comb-type silicone graft polymer as the binder and coating the charge generating layer.

The coordinates of a point P1 on a plane W1 which is in parallel with the (x) axial line, a point P2 on a plane W2 and a point P3 on a plane W3 which is in parallel with the (y) axial line are measured with the touch sensor of the main body of the measuring apparatus. The three points are measured one after another. The results are inputted into a minicomputer. In the computer, the deviation amount O1O2 and the angle theta are obtained by the specified computing expressions. Therefore, the arrangement of the object can be measured accurately even if two or more measurable holes are not provided on the surface.

Abstract: PURPOSE:To prevent a recording paper from contacting developing devices to prevent dirt of the recording face by providing pneumatic devices which support the recording paper pneumatically and separating the recording paper from a developing device by the pneumatic device when the recording paper after development of each color is fed reversely. CONSTITUTION:A recording paper 26 is run in the direction of an arrow A by a take-up roll 27 for the purpose of recording one of yellow Y, magenta M, cyan C, and black B. A latent image is formed on a prescribed part of the recording paper 26 by an electrostatic recording head 15, and one of developing devices 21-24 is brought closely into contact with the recording paper 26 to develop the latent image. After recording of one color is terminated, the developing device used for this development is separated from the recording paper 26.

Title: Power supply device for display device
Inventor: TAGUCHI HIROTSUNE
IPC: G09G1/28
Filed: 1984-08-17
Abstract: PURPOSE:To avoid superposing a rush current and make it possible that power is turned on again immediately after power switch is opened, by flowing the rush current to a degaussing circuit when the rush current to a capacitor disappears and using a fixed resistance to disconnect the degaussing circuit after a prescribed time. CONSTITUTION:When power is turned on by closing of a power switch 2, a timer 16 is started and is operated after t1-number of seconds to close a switch 13. When this switch 13 is closed, the charging current to a capacitor 6 is charged through a ripple suppressing resistance 12 having a small resistance value, and therefore, a rush current suppressing resistance 11 is not overheated unnecessarily. A timer 17 is operated simultaneously with coming of the output of the timer 16 to close a switch 14, and a degaussing circuit 9 is operated. Thus, the rush current for power-on is flowed to the circuit 9 when the rush current to the capacitor 6 disappears, and the rush current is not superposed to that to the capacitor 6. Since a resistance circuit 10 is the fixed resistance, the stable rush current suppressing operation is secured even if the switch 2 is opened in the state, where the circuit is warmed up sufficiently after power on, and is closed again immediately.
