Title: Input device for japanese sentence
Inventor: ISHIKAWA HIROISA
IPC: G06F17/22
Filed: 1986-07-19
Abstract: PURPOSE:To attain the easy input of Japanese sentences not only with a KANA (Japanese syllabary) keyboard but with a Roman character keyboard of alphabet letters is easy remembrance for keying, by sorting the codes of basic KANJI (Chinese characters) suppressing occurrence of homonyms into similar sounds and similar meanings for each syllable. CONSTITUTION:The basic KANJI are defined by storing chiefly those KANJI of similar sounds and similar meanings having high using frequencies in plural shifts for each syllable undergoing keying through a KANA keyboard or an alphabet keyboard. While many other KANJI are stored as the applied KANJI in relation to phrases and similar meanings against the basic KANJI. With such a device (not shown in this diagram), the basic KANJI are selected by pushing the corresponding shift keys at the head of each syllable and reading. While the stored phrases including basic KANJI and the applied KANJI are selected by pushing the prescribed shift keys together with keying of the Japanese reading of the applied KANJI before keying of the basic KANJI. Then the stored phrases consisting of the applied KANJI only are selected by pushing the prescribed shift keys and then the Japanese reading keys.

Title: Method for detecting end of etching
Inventor: SEKIGUCHI DAISUKE
IPC: C23F4/00
Filed: 1986-07-17
Abstract: PURPOSE:To carry out accurate and stable etching independently of exhaustion of an etching soln. when metallic layers on semiconductor substrates are etched, by measuring the concn. of a gas generated so as to detect the end of etching time. CONSTITUTION:A hydrogen detecting sensor 2 is fitted to the lid 5 of a treatment tank 1 filled with an aqueous phosphoric acid soln. 4 as an etching soln. In accordance with the progress of etching, gaseous hydrogen 8 is generated from semiconductor substrates 7 arranged in a holding jig 6 and a hydrogen atmosphere 9 is formed on the surface of the soln. 4. The sensor 2 detects the hydrogen 8 and a hydrogen detector 3 outputs an electric signal corresponding to the concn. of hydrogen. The progress of etching is quantitatively judged by the signal, and the time when a change in the concn. of hydrogen detected with the lapse of time becomes zero can be considered to be the end of etching. Thus, accurate and stable etching can be carried out.

IPC: B65G65/48
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a sealing member which can generate a large contact pressure using a less pressing force without risk of forming a gap. SOLUTION: When this sealing member concerned is used as a side seal for a rotary valve, the side seal 3 is made from an elastic material such as resin or rubber in a ring form having an angular section and has a seal surface 3a such that the part of the outside surface nearer the inside in axial direction of a rotor 12 is inclined so that the wall thickness declines toward the inside, and the inclination angle θ0 of the seal surface 3a is set so as to be slightly smaller than the inclination angle θ1 of the interior wall surface 11a of a liner 11. Thereby the wall thickness to be crushed through elastic deformation is made greater in a position nearer the innermost so that it is possible to stand a peak of contact pressure in the inner portion of the seal surface 3a.

Abstract: PURPOSE:To contrive to enhance a humid-proof characteristic by a method wherein a size of a filler mixed into sealing resisns is made smaller than an interval between electrodes formed on a semiconductor chip. CONSTITUTION:A filler 10 has a particle size which is smaller than an interval among respective electrodes 4 which are a plurality of pump electrodes 4 formed on a semiconductor chip 3 and is mixed into sealing resisns 1 with which the semiconductor chip 3 and the plurality of electrodes 4 formed on the semiconductor chip 3 are coated. Thus, since the particle size of the filler 10 mixed into the sealing resins is smaller than the interval between the bump electrodes 4 formed on the semiconductor chip 3, the sealing resisns 1 are invaded among the respective electrode 4 together with the filler 10, and as a result a gap between the electrode 4 is not caused and the surface of the chip 3 is completely coated with the sealing resins 1. Thus, a dampproof characteristic is enhanced.

Title: Controller for stepping motor
Inventor: KIZAKI KANJI
IPC: H02P8/00
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To drive a rotor with high accuracy, even when a stepping motor is stepped out by detection the difference between the true position where the rotor is located actually and a current position and then correcting a control signal, depending on the difference thus detected. SOLUTION: When a stepping motor 26 is stepped out to the opening side, true stepping position where the rotor is actually located is closer to the opening side of an intake throttle valve 25 than the stepping position of the rotor recognized by an ECU(electronic control unit) 39. When the stepping motor 26 is stepped out to the closing side, true stepping position where the rotor is actually located is closer to the closing side of the intake throttle valve 25 than the stepping position of the rotor recognized by the ECU 39. A control signal, i.e., a target step, can thereby be corrected by detecting the difference between the true position where the rotor is actually located and a current position of the rotor recognized by the ECU 39. Consequently, the rotor can be controlled accurately, even if the stepping motor is stepped out.
