Patent JP-S6336565-A (JP)
Title: Manufacture of semiconductor device
Inventor: TOMIKI HIDEFUMI
IPC: H01L29/72
Filed: 1986-07-31
Abstract: PURPOSE:To form a contact hole at an arbitrary place in an element region so as to form an electrode and to make the dispersion of a contact area small, by depositing first and second films having different etching characteristics in an insulating film, which covers the side surface of the element region, sequentially performing etching, and providing the hole. CONSTITUTION:Insulating films 5 and 7 are formed so as to cover the side surface of an element region protruding from a semiconductor substrate 1. A first silicon oxide film 8, whose etching characteristics are different from the films 5 and 7, is deposited on the insulating films 5 and 7. A second silicon nitride film 9, whose etching characteristics are different from the film 8, is deposited on the first film 8. Thereafter, etching is performed so that the second film 9 is made to remain only at the side surface of said element region. With the second film as a mask, the first film 8 is etched. with the first film 8 as a mask, said insulating films 5 and 7 are etched. Thus a hole, in which a part of said element region is exposed, is provided. For example, after a polycrystalline silicon film 10 is deposited, only the upper part of the element of the polycrystalline silicon is etched away by an etch back method. Thus an electrode lead-out part is completed.

Title: Cassette tape deck
Inventor: YAMANAKA TAKEO
IPC: G11B15/087
Filed: 1985-08-14
Abstract: PURPOSE:To exhibit auto-reverse function by detecting the absence of reproduced output if the reproduced output does not exist over a certain time during tape running for reproducing, then fast forwarding automatically the tape, and detecting the end of the tape and reversing tape running automatically to restart reproducing. CONSTITUTION:When a cassette tape CT is driven forward, left and right outputs in the forward side of a head H are inputted to left and right audio amplifiers AL and AR through a switching gate SG by a signal FS indicating this state and are amplified there. Levels OL and OR are detected and are given to a NOR gate G1, and the output is '0' if either of inputs is '1', but the output is '1' to start a timer T if both inputs are '0'. Since a blank continued normally for several - several tens seconds between pieces of music or movements, the timer does not expire for parts between pieces of music or movements but expires only for the end of recorded contents if the timer is set to 15-20sec; and when the timer expires, a monostable multivibrator MM2 is operated and the output is given to a fast forwarding signal input FF. Thus, the blank time is minimized to eliminate defects of an auto-reverse mechanism.

Title: Storage battery saving type frequency synthesizer
Inventor: RICHIYAADO FUEISUTO CHIYAREN
IPC: H04B1/16
Filed: 1981-11-10
Abstract: The phase-locked loop section (10, 14) of the synthesizer is periodically disconnected from the battery supplied power by means of a switch (60). In order to prevent substantial drift of the phase-locked loop during such power interruption, means (22, 24) are provided for maintaining a control signal on the VCO (12) associated with the loop (10) that maintains the VCO frequency. By minimizing the frequency drift, the loop can be re-locked in a short period of time following each power interruption.

Title: Sliding device
Inventor: HARA HIDEKI
IPC: B65G1/04
Filed: 1992-06-12
Abstract: PURPOSE:To make it difficult to elongate a chain, which is used for sliding a middle in a longitudinal direction to a base, in a sliding device used for a stacker crane or the like. CONSTITUTION:A chain 22 is engaged with front and rear wheels 20, 21 mounted on a base 1 so as to form an endless condition, by which no cross part is generated in the chain 22. As a result, component force in a horizontal direction is difficult to generate in the chain 22, thus restraining elongation. Since a rack-shaped engagement piece 28 mounted on a middle 2 engages with the chain 22, the middle 2 slides, and by interlocking with this, a top 3 slides in the same direction.

Abstract: PURPOSE:To obtain different refractive indices without changing radiating amts. of electron beams when polymer optical waveguides are produced by electron beam drawing method by providing a production device for polymer optical waveguide with a mechanism to introduce gas into a drawing room where a sample is patterned with electron beams. CONSTITUTION:A gas is introduced by using a variable leak valves and the sample is irradiated with electron beams in this atmosphere. However, the gas causes contamination in the electro-optical system of an electron gun and decreases the life of the filament of the electron gun. Therefore, a differential evacuating system is inserted between an electron beam irradiating room and the electro-optical system to improve the vacuum degree in the electron gun system. After a polyimide soln. or polyamide acid soln. is applied on a substrate such as silicon by spin coating, the coating film is heated to remove the solvent, and if necessary, the film is cured to obtain a polyimide film. Then, the substrate is introduced into the device to produce a polymer optical waveguide. The device is first evacuated to be vacuum, into which proper gas is introduced till a specified pressure is obtd. In this atmosphere, the film is irradiated with electron beams to obtain specified refractive index to obtain the optical waveguide.

Title: Signal transmission system of semiconductor integrated circuit
Inventor: KAWASHIMA SEIICHI
IPC: H03K19/0175
Filed: 1981-11-09
Abstract: PURPOSE:To perform stable in-phase transfer, by providing an intermediate latch between in-phase transfer latches, and supplying it with a timing signal complementary to the timing signal of the in-phase transfer latches. CONSTITUTION:Serial latches 41-43 are in-phase transfer latches 41 and 43 controlled by the same timing signal and an intermediate latch controlled by a timing signal complementary to said timing signal, and they perform transfer operation with characteristic time lags t11, t21 and t61 behind the timing signal. Even if the timing signal varies in width according to the complementary timing signal, a state change of timing is made at the same time at the same time to perform stable operation without depending upon the pulse width of the timing signal, and the signal latched by the latch 41 is transferred in an in-phase state from the latch 43 at next timing. Further, both timing signals are generated on a semiconductor chip to reduce the influence of a timing skew, and the signal transmission system of a semiconductor integrated circuit which perfoms stable operation is obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce a communication time and to attain reduction of gate number of an IC by making an interrogator transmit a command frame attached by an error detection code that is set by a fixed communication area and a responder calculate the error-detecting code and, responding to the command from the interrogator when a calculation result is correct. SOLUTION: When a responder 2 enters a communication area of an interrogator 1a, it calculates an error-detecting code (CRC). In a CRC 2 calculation circuit of the responder 2, when the last bit of a CRC 1 frame is inputted, a calculation of the CRC is not matched. Then, the responder identifies that the responder is not used in a specified communication area and stops the following operations such as response. Meanwhile, when the responder 2 enters a communication area of the interrogator 1b, it starts the calculation of the CRC after it receives a header similarly upon entering the communication area. A calculation result after the reception of the last bit of the CRC 2 frame is matched with a given expected value and it is recognized to be correctly communicated, and a reply to the interrogator 1b is performed.
