Title: Manufacture of semiconductor device
Inventor: IKEDA TADASHI
IPC: H01L29/72
Filed: 1977-11-14
Abstract: PURPOSE: To secure the ultra-high speed action through an extreme reduction of the occupied area of the unit transistor by forming the base region with the Si layer forming the effective base layer and the poly-Si layer for lead-out use.  
     CONSTITUTION: N-epitaxial layer 23 is provided to P - -type substrate 1 via N + - type buried layer 2a and then isolated via P + -layer 1a. And layer 2a is led out through N + -layer 2b. With the vapor growth of the N-epitaxial layer on insulating film 24, both single-crystal layer 25a and poly- crystal layer 25b are formed simultaneously. The selective etching is given after the P-type diffusion, and insulating film 34 is coated.Then N + -layer 26 and 2c are formed by giving the selective openings to film 24 and 34, and electrode 12, 35 and 36 are provided. In such constitution, the collector-base junction capacity is reduced greatly although the occupied area of the emitter is identical to the conventional area, thus featuring a high cut-off frequency. Furthermore, the occupied area of the element is reduced due to the reduction of the base layer area, thus obtaining a high concentration.

Title: Memory control system
Inventor: TAKEBE TOSHIO
IPC: G06F12/00
Filed: 1984-06-30
Abstract: PURPOSE:To attain the transfer of data at a high speed in a read mode with use of a low-speed memory element by writing data on the low-speed memory elements which are selected successively and then reading out those data collectively with the same address. CONSTITUTION:A prescribed lower bit of an address given from a microprocessor unit is decoded by a decoder 16, and low-speed memory elements 11-14 are selected successively via OR gates 17-20. Then data are written on elements 11-14 with the same address sent from a driver 15. These data receive the access from the same refresh address given from a CRT controller via an address driver 21. Then the data are read simultaneously and collectively out of the elements 11-14 which are selected en bloc by the CRT controller. Thus it is possible to transfer data at a high speed in a read mode by means of the low- speed memory elements.

Patent JP-H11324863-A (JP)
Title: Fuel injection nozzle
Inventor: DATE KENJI
IPC: F02M61/16
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To restrain irregular abrasion of a valve portion constituted with a valve member and a valve seat. SOLUTION: Because a fuel supply hole 32 for supplying fuel from outside to a fuel sump 33 is formed tangentially of the outer peripheral surface of a needle valve 20, the needle valve 20 is added with force tangentially of its outer peripheral surface and is rotated. Therefore, even when an axis of a contact portion is displaced from that of a valve seat due to machining error or others, place where the contact portion collides against the valve seat varies. Therefore, the irregular abrasion of the contact portion and the valve seat can be restrained, sheet area between the contact portion and the valve seat can be kept almost constant, and fuel can be prevented from leaking from a contact place between the contact portion and the valve seat.  Because outlet part 32b is positioned in the fuel upstream of a nozzle body 11, fuel flowing into an injecting hole becomes uniform and an injection characteristic can be prevented from varying.

Title: Indicator for rotation direction of tape
Inventor: KITANO KAZUMITSU
IPC: G11B33/02
Filed: 1986-06-12
Abstract: PURPOSE:To recognize the rotation direction of a tape by observing a reel turntable externally by providing a transparent window of a convex lens shape whose center position is shifted in an optional direction to the center position of the reel turntable to a cassette holder. CONSTITUTION:The transparent window 8 formed as a convex lens is provided to an upper cabinet 4 of a cassette holder to recognize the rotation direction of the reel turntable 9. Since the center of the transparent window 8 is shifted from the center of the reel turntable 9 in an optional direction, in looking at it from the direction of an arrow B, a hub 11 of a cassette tape 10 is magnified by the lens effect of the transparent window 8. Thus, when the reel turntable is driven 9 in either the arrow C or D, the hub 11 is driven at the same time and the tape running direction of the cassette tape 10 is recognized from the rotation direction of the hub 11 observed with magnification.

SOLUTION: The backing material is formed by the urethane resin obtained by reacting the polyol in the water-absorptive resin dispersion and the polyisocyanate compound. At this time, the water-absorptive resin dispersion is composed by dispersing the water-absorptive resin or its water absorption gel into the polyol. According thereto, the water-absorptive resin is dispersed in a small particle form and, therefore, the surface area per unit weight of the water-absorptive resin may be increased. Then, the water absorption rate and the moisture releasability may be improved. Polyether polyol and polyester polyol are used for the polyol. A water-soluble vinyl monomer or a polymer formed by polymerizing its precursor and a crosslinking agent is used for the water-absorptive resin.
