Inventor: FUKUDA IKUO
IPC: H01L31/12
Filed: 1983-11-25
Abstract: PURPOSE:To satisfy characteristics and reliability between light-emitting and light-receiving elements even when fillers in an internal molding layer are reduced by forming a recessed section or a projecting section to the surface of an internal resin layer in a double molded optical coupling element. CONSTITUTION:A light-emitting element pellet 12 and a light-receiving element pellet 13 are mounted oppositely at each nose section of lead frames 11, 11'. Grooves or irregularities are shaped in the direction that the length of the interfaces A-A', B-B' between the light-emitting and light-receiving elements is lengthened to the surface of an internal molding layer 15 by using a transparent resin as the layer 15. Consequently, transmittance, conversion efficiency, can be increased, and the length of the interface between the internal molding layer 15 and an external molding layer 16 is lengthened, and adhesive properties are improved.

IPC: H01L21/225
Filed: 1989-08-28
Abstract: PURPOSE:To uniformly and simply form a shallow-junction As diffusion region in a prescribed part of a semiconductor substrate by a method wherein a sheetlike solid supply source composed of an As compound is used as a supply source of As as impurities, it is arranged at a specific interval so as to be faced with a semiconductor substrate to which the impurities are to be diffused and a heat treatment is executed inside a lamp heating apparatus. CONSTITUTION:A sheetlike body 3 of an As compound and a semiconductor substrate 4 are arranged so as to be faced nearly in parallel and at a close interval of less than 3mm. A silicon semiconductor substrate is suitable for the semiconductor substrate 4; a compound which is decomposed or evaporated by heating and which can release As2O3 gas or SiAs gas is suitable for the As compound. A heat treatment is executed inside a lamp heating apparatus; as a heat-treatment temperature, a decomposition temperature or higher or an evaporation temperature or higher of the As compound is applied; normally, it is 900 to 1000 deg.C. A heat-treatment duration is about 10 to 60sec. When the duration is less than 10 sec, As is diffused insufficiently. When it exceeds 60 sec, As is diffused excessively; as a result, it is difficult to form a shallow- junction diffusion region.

Title: Magnetic video recording and reproducing device
Inventor: OOKAWA KAZUTAKA
IPC: G11B27/32
Filed: 1983-11-26
Abstract: PURPOSE:To attain accurate program searching with simple constitution by detecting a video record starting position based on the number of pulses and the cycle of a pulse train recorded on a cue track when a magnetic tape is shifted adversely. CONSTITUTION:A pulse train 51 is reproduced by a cue head 10 in the rapid traverse and rewind modes of a magnetic tape T, and a CPU17 counts the number of pulses of the reproduced train 51. Thus it is possible to search the video recording start position as long as the train 51 is formed regularly. However the train 51 is discontinuous on a cur track 50 in case the procedures from stop to record or from record, temporary stop and record are repeated or coexist. This secures no accurate program searching. In this example, however, the program searching is possible despite a discontinuous state of the train 51 since the video record starting position is detected based on the number of pulses and the cycle of the train 51.

In the process, phosphoric acid (e.g. orthophosphoric acid) in an amount of preferably about 0.01-5mol% based on the higher fatty acid or its ester is added to carry out the reaction. Thereby, the objective imidazoline compound expressed by formula III is obtained. The high-quality imidazoline compound with a low diamide content can efficiently be obtained by simple operation according to the above-mentioned method. The imidazoline compound expressed by formula III in itself is useful as a surfactant.

Title: Kana-kanji conversion system
Inventor: NISHIKAWA NOBUO
IPC: G06F17/22
Filed: 1985-10-07
Abstract: PURPOSE:To automatically correct the length of a conversion object character string by regarding a following candidate request for the last candidate as a shortening request of the conversion object character string and regarding a preceding candidate request for the first candidate as an extending request of the conversion object character string. CONSTITUTION:A character string inputted from a keyboard 10 is not only inputted to an input buffer 14 but also displayed on a display part 34. When a conversion key is depressed, a continued clause KANA (Japanese syllabary)-KANJI (Chinese character) converting part 16 retrieves an independent word dictionary 18 and an adjunct word dictionary 20 to convert said character string to a sentence with KANJI and KANA mixed, and this sentence is displayed. When a following candidate key is depressed, the converting part 16 selects and displays the following candidate; but if the following candidate key is depressed when the last candidate is displayed, the converting part 16 shortens the length of the conversion object character string by one character and performs retrieval again to display conversion results. If a preceding candidate key is depressed when the first candidate is displayed, the length of the conversion object character string is extended by one character and retrieval is performed again thereafter to display conversion results.

IPC: G06F40/189
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To save the trouble to edit a document by re-editing the layout of data which deforms owing to a change when the format data (form size) attached to data in a storage device is changed. SOLUTION: When a 're-layout' indication is sent from a storage device 3 to the document preparation device, a CPU 5 scans the document data in the storage device 4, line by line, and analyzes and classifies the positions of respective character strings, laid out in the document data, in respective lines. After the analysis, the CPU 5 stores a storage device 4 with a set of three items, i.e., an attribute such as 'right justification', 'left justification', 'centering' and 'others (not character string, figure, etc.)', page number, and a line number for each character string. When new form size is inputted from an input device 3, a character string control part 7 justifies all the respective of the document data to the left. Then the format of the document data is changed according to calculated data.  Further, the character string control part 7 arranges the document data in a printable (display) range.

Title: Displacement sensor
Inventor: MITSUSHIMA KOICHI
IPC: G01B7/00
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To provide a novel electric current detection-type displacement sensor capable of detecting fine displacement. SOLUTION: Electrodes 5, 9 are mounted opposite to each other with a clearance. One of electrodes 5 is a silicon needle electrode, and consists of needle- shaped silicon cones having tapered points. The silicon needle-shaped cones having micromasks as vertexes, are formed by high selective ratio anisotropic etching of a silicon substrate or a silicon layer while using an impurity deposition area formed in the silicon substrate or the silicon layer as the micromasks. This sensor detects an electric current flowing between the electrodes when the voltage is applied to the electrodes, and the displacement is determined by utilizing the change of the current corresponding to a distance between the electrodes. When the vacuum is applied between the electrodes, a tunnel current flows, and when a gas is sealed between the electrodes, the discharging is produced.
