Title: Recording system for memory magnetic disk
Inventor: FUKUSHI KOJI
IPC: G11B5/09
Filed: 1985-05-31
Abstract: PURPOSE:To increase the recording density of a magnetic disk by several times as high as the conventional density by recording data after dividing a magnetic layer into plural parts of different levels of recording depth. CONSTITUTION:The current of the recording signal supplied to a head 2 in a record mode is set at a level higher than the current of the recording signal supplied to a head 6. Thus the recording magnetization done by the head 2 has the larger recording depth than the head 6 to a magnetic layer 10. At the same time, the recording magnetization depth of the head 6 is relatively reduced. In other words, the signal sent from a terminal 1a is recorded down to the lower part of the layer 10 by the head 2. While the signal sent from a terminal 1b is recorded only to the upper part of the layer 10 by the head 6. Thus the layer 10 is divided into upper and lower layers an the data are recorded to these two layers respectively.

Title: Electric japanese language typewriter
Inventor: WATASE FUMIO
IPC: B41J3/01
Filed: 1981-07-29
Abstract: PURPOSE:To reduce an occupying space with a smaller size of a motor by a method wherein a light type bar alone is moved horizontally to pick up types from a type tray with longuitudinal movement thereof, shifted to the printing position and returned to the original position after the printing. CONSTITUTION:A code of characters to be printed and position information are recorded on an external recorder, for example, a paper tape. In typing, the information is read with a processing section to control a motor 7 so that a type case 6 is moved longuitudinally to bring a type train containing intended characters below the level of the type bar 8. At the same time, with the driving of the motor 9, the type bar 8 moves to the line corresponding to the intended characters to pick up the characters and then, shifts to the printing position. A platen 12 is turned with a motor 13 to match the vertical printing position and the type bar 8 is turned with a motor 11 through a supporting member 10 to perform a printing. Then, the types are stored in place. This eliminates a heavy type tray and the horizontal movement of the platen thereby reducing the size and the number of the motor. This also enables the use of continuous paper and reduction in the occupying space on the desk.

Title: Semiconductor device and manufacture thereof
Inventor: SHIRATO TAKEHIDE
IPC: H01L29/78
Filed: 1983-06-30
Abstract: PURPOSE:To prevent the deterioration of dielectric resistance between a source and a drain on a short channelling without increasing high-temperature running processes and without augmenting junction capacitance. CONSTITUTION:A p channel transistor (p-ch) of the same conduction type as a substrate 11 is formed in an n well 12 in comparatively high impurity concentration shaped by compensating the concentration of the substrate. Consequently, a depletion layer hardly extends into the well 12 when voltage is applied between source and drain regions 19a, 19b in the transistor p-ch. A p type region 16, which is selectively deeper than n<+> type source and drain regions 20a and 20b and has impurity concentration higher than the substrate 11, is formed to a section just under a gate electrode 18b in an n channel-transistor (n-ch) with a conduction type channel reverse to the substrate 11 and between the regions 20a and 20b. Accordingly, the deterioration of source and drain dielectric resistance by a punch-through phenomenon is inhibited because the extension of the depletion layer between the regions 20a, 20b is inhibited to a small value. Excessive high-temperature running processes can be omitted by forming the p type region 16 through ion implantation and the activating treatment of an implantation region.
