Title: Manufacture of visible light semiconductor laser
Inventor: AOYANAGI TOSHITAKA
IPC: H01S5/00
Filed: 1989-03-08
Abstract: PURPOSE:To obtain a visible light semiconductor laser which is superior in quality by raising a temperature in an atmosphere of phosphine after removing a mask. CONSTITUTION:A necessary crystal is grown on an n-type GaAs substrate 1 and patterned with a photoresist 8 which serves as a mask for etching to form a ridge. Then the resist 8 is removed and the temperature is raised in an atmosphere of phosphine. Then an n-type GaAs layer 9 is allowed to grow in an atmosphere of arsine by MOCVD. An n-type GaAs layer 11 grown on the layer 9 and the ridge is etched slightly. Then its crystalline property is reflected and only the layer 11 is etched selectively. Finally such a treatment makes a p-type GaAs layer 10 grow. A visible light semiconductor laser that is superior in quality is thus obtained by a simple process.

Title: Rail clamp, clamping structure and fixing member
Inventor: HERUMUUTO AIZENBERUKU
IPC: E01B9/30
Filed: 1986-03-14
Abstract: The invention describes a clamp for rails that is produced from resilient steel bar with multiple bends. The first section (11) of the rail clamp (9, 10) is essentially horizontally arranged, while the last section (14) rests on the rail flange (5). The second section (12) curves upwards in the vertical plane that passes through the first section (11). The remaining sections of the clamp lie all on the side of the first section that faces the rail. The fastening arrangement comprises an anchoring part (20) where the supporting surface (23) for a supporting section of the clamp (9, 10) is located essentially vertically above the locating hole (24) of the clamp (9, 10). That produces a relatively short clamp requiring a minimum of material.

Title: Construction of counter electrode in emission spectrochemical analysis device
Inventor: FUKUI ISAO
IPC: G01N21/67
Filed: 1983-03-31
Abstract: PURPOSE:To make the evaporation of a sample owing to discharge uniform in the depth direction by gushing a gas from the gas introducing hole provided at the center of a counter electrode toward the sample. CONSTITUTION:A counter electrode 6 facing a sample 5 placed on a light emitting stand is formed to have 120-130 deg. opening angle at the tip 6a and is provided with a gas introducing hole 7 at the center thereof. If spark discharge is generated without oscillation, the discharge spreads as the tip of the counter electrode is made into a concentrical circular shape; moreover, the probability of the discharge in the central position of the electrode 6 is decreased by the gas gushing from the hole 7. The surface part of the sample 5 is therefore evaporated uniformly overall in the depth direction and a discharge trace 10 having a flat bottom is formed. Then the separate emission of light from plating layers 5a, 5b is made possible and the coating weight of plating which is previously difficult to be analyzed is analyzed with high accuracy.

Abstract: PURPOSE:To effectively store data of serious accident by always monitoring occurrence date and hour of trouble data stored in an occurring order in a plurality of memories of a monitor for an electric railcar controller, and automatically erasing the data in which a predetermined time or more is elapsed from occurrence. CONSTITUTION:When a trouble necessary to be stored in a trouble monitoring device 10 occurs in a controller 1 for an electric railcar, data necessary to analyze the trouble is transmitted to a buffer 3 according to an output of a monitor trigger command 2. A counter 4 inputs the data of the accidents in an occurring order in memories 5-7 according to the output of the command 2. A trouble occurring date and hour monitor 9 always monitors the trouble occurrence date and hour of the memory 5, automatically erases the data of the memory 5 if a predetermined time has elapsed, and transfers the data of the memories 6, 7 to the memories 5, 6. The predetermined time is set shorter than a period in which occurrence of a slight accident is estimated and longer than a period of time from occurrence of a serious accident up to the time of inspection by a person in charge. Thus, the data regarding the serious accident can be effectively stored.

Title: Balance adjusting device for rotor
Inventor: ARITAKE HIROSHI
IPC: G01M1/16
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to carry out an accurate balance adjustment, by inserting and moving a ring-shaped insertion member between a fixed section and a seal member, pinching the seal member between the insertion member and a rotor, and forming a gap between the fixed section and the seam member. SOLUTION: When the balance of a rotor 1 is adjusted, a ring-shaped thin plate 7 is divided into multiple split plates with the same shape, the thin plate 7 is inserted toward the shaft center from the outside than the diameter corresponding to a contact section 11, and it is fixed to a holding component 8 with a fixing screw 9. The split plates of the thin plate 7 are arranged point- symmetrically with a rotary shaft. When the screw of a universal clamp 10 is rotated to pull the holding component 8 to the right direction, a seal member 5 is elastically deformed and separated from a fixed section 2. Even when the fixed section 2 and rotor 1 are relatively rotated, a gap is generated between the seal member 5 and the fixed section 2, the seal member 5 is not slid, and the static friction around the shaft is caused merely by a bearing 3 and wires 6 and becomes small.  The balance can be adjusted without being affected by the static friction of the seal member 5.

Title: Character recognizing method of optical character reader
Inventor: HASHIMOTO TSUGUO
IPC: G06K9/00
Filed: 1991-02-28
Abstract: PURPOSE:To improve the name recognition rate and operability of an optical character reader by displaying candidate data and selecting a desired punctuation between a surname and given name out of the candidate data when a different punctuation exists against the surname and given name. CONSTITUTION:The operator of this optical character reader(OCR) writes a full name in Kanji (Chinese characters) and Kana (Japanese syllabary) letters indicating the reading of the Kanji by hand on the prescribed slip, etc., of the OCR. Then a scanner section 41 reads the full name written in the Kanji and a recognizing section 42 sends its recognized results, namely, the inputted Kanji and data indicating the presence of another candidate corresponding to the Kanji to a control section 1. The section 1 processes and outputs the candidate data from the recognized result data of the inputted full name written in the Kanji. Thus the operator can select a desired punctuation of a surname and given name from the displayed candidate data and decide a correct full name by checking the presence of another punctuating method against the same surname and given name and displaying the candidate data.

Title: Radio wave absorbing wall
IPC: H05K9/00
Filed: 1991-02-28
Abstract: PURPOSE:To provide a durable radio wave absorbing wall which effectively absorbs electric waves in a wide band. CONSTITUTION:A concrete or mortar concrete wall member 1 is provided and a plurality of conductive wires 2 are buried parallel to the external surface of the concrete wall member 1 at almost the same intervals at the prescribed place in the concrete wall member 1.
