Title: Hydrogen storage electrode
Inventor: FURUKAWA ATSUSHI
IPC: H01M4/24
Filed: 1992-04-23
Abstract: PURPOSE:To provide a hydrogen storage alloy electrode excellent in the rapid discharging characteristics and the inner pressure rise suppressing effect by using a carbonyl nickel powder, whose chain part has a specific mean diameter, as a conductivity generating agent to be added to a hydrogen storage alloy powder. CONSTITUTION:Mm, Ni, Co, Al, are mixed in a certain proportion and melted with heat by the high frequency melting method, followed by cooling, to prepare a hydrogen storage alloy. Carbonyl nickel powder as a conductivity generating agent and a powder of polyvinylidene fluride as a binding agent are added to the powder obtained by crushing a lump of the mentioned alloy, and they are mixed thoroughly. The carbonyl nickel powder used is prepared so that the mean dia. of its chain part diverging three-dimensionally in a great number of branches ranges from 0.8 to 1.3mum. This range allows it to present a large rapid discharge capacity and also a large suppressing effect for the rise of the gas inner pressure. Thereby the rapid discharge characteristics and the inner pressure suppressing effect can be enhanced by forming a hydrogen storage electrode using carbonyl nickel powder.

Filed: 1994-06-13
Abstract: PURPOSE:To make the structure relatively simple and to obtain an excellent key touch feeling and stable string striking operation in either of a normal musical performance and a string non-striking musical performance. CONSTITUTION:A turning force point changing mechanism 62 is arranged corresponding to a large jack 13A. The turning force point changing mechanism 62 is moved into the motion area of the large jack 13A at the time of the string non-striking musical performance. A projection part 21 provided to the large jack 13A abuts on the turning force point changing mechanism 62 in the string non-striking musical performance and then a jack 13 rotates around the projection part 21 as a turning force point to disengage. When the distance from the turning force point to a pin 15 is set shorter than the distance from the pin 15 to the projection part 20 of a small jack 13B, the rotating speed of the jack 13 at the time of the disengagement becomes fast. A stopping means 61 stops a hammer shank 25 from rotating in the string non-striking musical performance right before a hammer 26 strikes on strings 3.

IPC: G06F3/01
Filed: 1981-08-19
Abstract: PURPOSE:To quickly select character data by reading out the character data in the order of the Japanese syllabary or the leading character of each line by the different operations of an operating device.

IPC: H01F10/13
Filed: 1984-06-25
Abstract: PURPOSE:To obtain a soft magnetic film for a pole piece to realize a thin film magnetic head of high electromagnetic conversion efficiency by laminating at least two layers of an amorphous soft magnetic thin film layer consiting of Co- metal series or Fe-Co metalloid and a crystalline soft magnetic thin film layer. CONSTITUTION:For example, a soft magnetic laminated film is composed by alternately laminating four crystalline soft magnetic thin film layers 13 consisting of 500Angstrom  film thickness NiFe alloy and three CoZr amorphous soft magnetic thin film layers 12 of 3,000Angstrom  film thickness on a substrate 11 made of glass or ceramics using thin film formation technique such as sputtering or evaporation. In order to realize magnetic coupling of each layer during manufacture of the laminated film, the film is made in magnetic filed in order to make the axis of easy magnetization of each layer composing the above-mentioned laminated film in the same direction. This greatly improves the secular change of permeability, can restrain the generation of anisotropy in the amorphous soft magnetic thin film and can obtain an excellent material for the pole piece of a thin film magnetic head.

Title: Insulated-gate semiconductor device and manufacture thereof
Inventor: SATO MASAKI
IPC: H01L27/06
Filed: 1986-06-05
Abstract: PURPOSE:To improve the operating speed of a circuit, by constituting a part of the drain region of an N-channel transistor, which is directly connected to an output terminal at a position where a high power source voltage is directly applied, in as diffused region, whose impurity concentration is relatively low. CONSTITUTION:As shown by as circle in the Figure, only the drain of an N- channel MOS transistor, which is directly connected to terminal for an output signal Vout, has an N-type impurity diffused region 20, whose impurity concentration is set at a relatively low value. Parts, which are contacted with a source and the channel region of a drain shown by squares in the Figure have N-type impurity diffused regions 15B, 16B and 18B, whose concentration is one order of magnitude higher than that of the N-type impurity diffused region 20. The resistance value of only the N-type impurity diffused region 20 is high. Therefore the resistance between the output terminal of the signal Vout and Vss is mainly caused by the N-type impurity diffused region 20. Thus the high-speed operation can be achieved.

IPC: G11C13/06
Filed: 1983-07-20
Abstract: PURPOSE:To increase the apparent angle of Kerr rotation and to obtain reproduced light with a high S/N ratio by forming a reflecting layer and/or a dielectric layer so as to make use of Faraday rotation besides Kerr rotation. CONSTITUTION:A reproducing layer 2 of GdFe, GdFeBi or the like having a large angle of Kerr rotation and a recording layer 3 of TbFe, DyFe or the like having a low Curie temp. are successively formed on a transparent substrate 1. Each of the layers 2, 3 has such a thickness as to transmit light. A reflecting layer 5 of Au, Ag, Cu or the like is formed as the uppermost layer. By this structure, the apparent angle thetak of Kerr rotation is increased by combining Kerr rotation by the Kerr effect produced by the reflection of incident light by the surface of the layer 2 with the Faraday rotation of a plane of polarization by the Faraday effect which is exerted on the light when the light passes through the layers 2, 3 as magnetic layers and passes through the layers 3, 2 again after reflection by the layer 5, so the S/N ratio is improved. A dielectric layer 6 may be formed to cause Kerr rotation and Faraday rotation plural times.
