Patent JP-S63205927-A (JP)
Title: Manufacture of semiconductor device
Inventor: OKADA HIROYUKI
IPC: H01L21/76
Filed: 1987-02-23
Abstract: PURPOSE:To prevent etching of a thin silicon oxidizing film and a LOCOS oxidizing film, by forming a silicon nitriding film on groove side walls so as to cover exposed parts of grooves which exist on end parts of the thin silicon oxidizing film. CONSTITUTION:A first silicon oxidizing film 3, a first silicon nitriding film 4, and a CVD oxidizing film 5 are formed on a surface of a silicon substrate 2, and groove opening parts 6 are formed by photoetching. The oxidizing film 5 is used as a mask to form grooves 7. A second silicon oxidizing film 8 is formed inside the grooves 7, and a second silicon nitriding film 9 is formed all over the surface. The nitriding film 9 is anisotropically etched so that it remains on side walls of the grooves 7. The oxidizing film 5 is etched. Thereupon, the LOCOS oxidizing film 1 is not etched at all because the end parts of the oxidizing film 3 are protected by the nitriding film 9. The substrate 2 parts exposed at the bottom of the grooves 7 are oxidized to remove the nitriding films 4 and 9.

Title: Integrated logic circuit
Inventor: HOSHIZAKI TERUHIRO
IPC: H01L27/04
Filed: 1987-02-23
Abstract: PURPOSE:To set a desired output state without performing long-time logical operation, by providing a counter circuit and a selector circuit. CONSTITUTION:A counter circuit 5 and a selector circuit 6 are added between an internal logic circuit 1 and an output buffer circuit 2. In usual logical operation, a terminal 4 is held to an '1' level and the circuit 6 outputs the signal corresponding to the state of the circuit 1 to an output terminal 3 through the circuit 2. In the test of this integrated logical circuit, the output characteristic of the circuit 2 is tested but, in this case, when a '0' level signal is applied to a terminal 4, the circuit 6 outputs the signal level corresponding to the output 7 of the circuit 5 to the terminal 3 through the circuit 2 and, therefore, all of outputs can be set to '0' or '1'. Since an output level is determined according to the state of the circuit 5, it is not uniquely determined whether output becomes either one of '0' and '1', by the input signal level to the terminal but, when '1' level and '0' level signals are continuously applied to the terminal 4, the output of the circuit 5 can be reversed and a desired output state is obtained.

IPC: G11B5/127
Filed: 1982-03-16
Abstract: PURPOSE:To prevent the change in the width of gaps and the deviation in the position of tracks and to stabilize characteristics by butting one block to the other block while brazing members are left in a part of grooves for winding windows and heating the blocks to melt the brazing members. CONSTITUTION:Brazing members 3 are beforehand packed in a groove 1a for a winding window and a groove 1b for brazing, and joint surfaces (c) are worked to mirror surfaces. The members 3 in the groove 1a are removed by rotary  grinding or the like except the necessary parts thereof. The block is butted in  this state to the other block 2, and the blocks are heated in air or a vacuum to melt the members 3, thereby joining the right and left blocks 1, 2 integrally.  The joined block is sliced at a broken line A to obtain magnetic head cores 4.  Since the blocks are joined to each other at the two places, the head cores have high mechanical strength and are free from the change in the width of gaps and the deviation in the position of tracks.

Title: Side run winding core and its usage
Inventor: KAKISAKA KAZUNORI
IPC: B65H19/22
Filed: 1988-02-23
Abstract: PURPOSE:To make it possible to easily remove a core from a winding body after using the core by forming a cylindrical body of the core made of elastic material with a notched part in a direction of its generating line, and both end faces of the notched part into a tapered face widening inward to insert a key. CONSTITUTION:A cylindrical body 10 of a core fitted on a shaft 4 is made of elastic material, and provided with a stripe of a notched part 12 in a direction of its generating line. Both end faces 13 of the notched part are formed into tapered faces widening toward an inside hollow part 14 of the body 10. When the body 10 is fitted on the shaft 4, it expands against elastic force into a cylindrical shape, and a key 15 widening toward the inside end is pushed into the notched part 12 expanded as above-mentioned, and a side run is wound on the body 10. When the core is then removed from the shaft 4, the elastic force of the body 10 makes the key 15 fall off into the hollow part 14. The body 10 therefore shrinks, and can be simply removed from a side run winding body.

IPC: H04L5/14
Filed: 1987-02-25
Abstract: PURPOSE:To attain bidirectional long distance communication by cancelling a signal reflected from a first conductor by an impedance mis-matching with a signal reflected from a second conductor. CONSTITUTION:When a first channel side terminal 12L is watched from an impedance element 9L, it appears as if an impedance element 9R exists at the leading of a conductor 15. When a second channel side terminal 13L is watched from an impedance element 8L, it appears as if an impedance element 11R exists at the leading of a conductor 16. The electrical conditions of conductors 15 and 16 are the same, and the impedance value of impedance elements 9R and 11R are both equal to Z. Therefore, an impedance value Z1 is equal to an impedance value Z2. Consequently, both inputs of a subtracting circuit 10L are equal, any signal does not appear between a receiving side terminal 5L and a receiving side ground terminal 6L. Namely, an echo does not occur. Thus, a small and an inexpensive communicating equipment, in which the bidirectional long distance communication can be attained, can be realized.
