IPC: G11B23/02
Filed: 1987-12-14
Abstract: PURPOSE:To obtain a cartridge light in weight but rigid by producing a peripheral frame among the three parts constituting the cartridge with a highly rigid substance such as a light metal, etc., and producing the upper and the lower covers with a light weighted synthetic resin. CONSTITUTION:The cartridge 1 is constituted of peripheral frame 2 approximately shaped square and upper and lower covers 3, 4 also in approximate square shape that are mounted on the frame 2 from above and from under it 2. In such a cartridge 1, a disk 5 which is a disk-shaped recording medium is contained. The peripheral frame 2 is constituted of a highly rigid member of such as a light metal, while the covers 3, 4 are made of light-weight synthetic resin, hence the cartridge 1 is extremely light in weight.

Title: Method and mold equipment for injection molding
Inventor: INOUE YASUTOSHI
IPC: B29C45/00
Filed: 1986-12-26
Abstract: PURPOSE:To contrive to prevent a sinkmark from developing and consequently to shorten the time required for correcting a mold to a far greater extent by a method wherein gas such as compressed air or the like is forcibly fed in a cavity at the contrived timing during molding. CONSTITUTION:After a molten plastic material is filled into a cavity 3, gas is fed through a passage made in a core pin 4 from the tip of the core pin 4 into the plastic material so as to cool a mold and to contrive to solidify the plastic material in order to be able to mold a molded item equipped with a boss part 10. In the molded item as mentioned above, no sinkmark develops on the surface of the boss part. If the temperature of the gas which is forcibly fed from a gas feeding device 6 to the passage of the core pin 4 is controlled so as to contrive to cool the core pin 4, the shortening of the molding time also results. The timing for forcibly feeding the gas in the passage 8 of the core pin 4 is after the filling of the plastic material. Further, the optimum protruding length of the tip part of the core pin 4 is determined in accordance with the conditions of the molded item such as wall thickness and the like.

Inventor: JIYON II BAAGU
IPC: H01L29/78
Filed: 1989-12-05
Abstract: PURPOSE: To reduce the floor capacity of source-drain junction by self-alignment of through injection between a gate electrode and source-drain region. CONSTITUTION: When the upper surface of a dielectric layer 12 has been completed, the dielectric layer 12 is removed by wet chemical etching, while a polysilicon electrode 24 is left in a trench 15. This etching does not remove the gate electrode layer 24, and a thin dielectric layer 28 remains. Next, high- dose injection is performed through the dielectric layer 28 so as to determine a source-drain region 30. Then, n-type dopant is injected into n-channel MOSFETs, p-type dopant is injected into p-channel MOSFETs, and annealed at a high temperature for a short period. Then, a dielectric layer and a metalized layer are deposited. This enables self-alignment of through injection 18 under the gate electrode, and reduces the junction floor capacity.

Title: Printer head
Inventor: FUTAGAWA YOSHIKIYO
IPC: B41J2/14
Filed: 1988-12-16
Abstract: PURPOSE:To form stable ink particles and to obtain a printer head of almost permanent durability by electrostatically displacing and releasing a movable piece put in ink. CONSTITUTION:When control parts 9a and 9b apply a voltage between electrodes, a movable part 9b is bent by Coulomb's force or electrostatic force. At this time, electric charges abruptly accumulated between the electrodes are discharged to release movable parts 5a and 5b, which oscillate to be displaced toward nozzles 7a and 7b at a speed related to a natural oscillation frequency. Owing to this force, a part of an ink 10 jets out in the direction of an arrow as ink particles 8a and 8b from the nozzles 7a and 7b. Since only the electrostatic force is applied between the fixed electrodes which are controlled independently and electrostatically in such a way, production is facilitated, and high printing quality can be obtained because of almost permanent and stable dot formation.
