Filed: 1991-11-15
Abstract: PURPOSE:To obtain a new data processing method which eliminates erroneous recognition. overlooking and the like of a transformation point. CONSTITUTION:In a transformation behavior measurement of steel or the like, a temperature-thermal expansion curve is prepared to determine a transformation starting temperature of a test piece from the curve while a temperature TR indicating transformation ratio selected from those of 20-50% selected optionally. Then, reaction constants as chemical components of the steel, working heat processing conditions and a compatibility variable are used as parameter to determine the transformation ratio at temperatures under specified cooling conditions. The reaction constant is changed until a deviation ¦TR-TR'¦ between the temperature TR' and the temperature TR corresponding to the transformation ratio is down below a specified value to determine the starting and ending temperatures of the transformations from a theory model. Thermal expansion values near the temperatures are differentiated by the temperatures to obtain the transformation start and end temperatures of transformation phases from changing points of differentiated values.

Title: Fabrication of insulated gate field-effect transistor
Inventor: NOGUCHI TAKASHI
IPC: H01L21/265
Filed: 1992-12-08
Abstract: PURPOSE:To enhance gate-drain (source) breakdown voltage by oxidizing a gate electrode to form an oxide film, removing the oxide film, implanting impurity ions using the gate electrode as a mask, thereby forming a lightly doped drain region and a source region. CONSTITUTION:A polycrystalline semiconductor gate electrode 3 is formed with a predetermined width on a semiconductor substrate through a gate insulation layer 2 and the surface of the gate electrode 3 is then oxidized to form an oxide film of predetermined thickness. The oxide film 4 is then removed by etching to leave the gate electrode 3 of width L1 which is used as a mask in the implantation of impurity ions thus forming a lightly doped drain and source regions 5, 6 on the semiconductor substrate 1. This method allows formation of an LDDMOS transistor having channel length shorter than that attainable by photolithography for forming the gate electrode 3 while enhancing gate-drain (source) breakdown voltage.

Title: Water supply structure
Inventor: OSUGA KAZUO
IPC: E03C1/02
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To relieve a water-hammering phenomenon to prevent water supply pipes or the like from breaking or unpleasant vibration sound from generating, by inserting a cut off valve side pipe formed by disconnecting a joint pipe and the front end part formed by cutting off a faucet side pipe into a hermetically sealed intermediate container and arranging the front end of the faucet side pipe at a lower level than the upper end of the intermediate container. SOLUTION: Water flowing in a water supply pipe 1 is supplied to a connection pipe 3 through a cut off valve 2 and the water in the connection pipe 3 is supplied to a faucet. In this structure, the connection pipe 3 is disconnected to form a cut off valve side pipe 6 and a faucet side pipe 7. And the cut off valve side pipe 6 and the disconnected front end of the faucet side pipe 7 are inserted in a hermetically sealed intermediate container 8 and the front end of the inserted faucet side pipe 7 is arranged at a lower position than the upper end of the intermediate container 8.  Accordingly, an air layer 10 is formed at the upper part in the intermediate container 8, and abrupt increase of the water pressure in the intermediate container can be prevented by compressing the air layer 10 by water vigorously flowing down from the cut off side pipe 6 into the intermediate container 8, when water is cut off by the faucet 4.

Title: Printed board manufacture and printed board
Inventor: KAJIYAMA YOSHIKUNI
IPC: H05K3/06
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To obtain structure wherein the narrow junction part of a printed board is hard to be cut, by arranging, if necessary, an I type junction part copper foil or a T type junction part copper foil, between cutting-out trenches. SOLUTION: I type junction part copper foils 100 are so arranged that the foils intersect junction part 51 between cutting-off penetration trenches 400. This is performed by leaving a copper foil formed on an original board by an etching process. When a force is applied to the junction part 51 until electronic components are mounted by an automatic mounting equipment, cutting-off is scarcely generated, because the junction part 51 is protected from above and below a double-sided board by the copper foil 100 for reinforcement. Thereby generation of warp and distortion is excluded, and reduction of manhour and improvement of yield can be realized.

IPC: G11B5/39
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To provide the manufacturing method which can form a couple of leads for obtaining narrow track width. SOLUTION: A lead layer 16 is formed of a bias magnet film and an electric conduction film on a reproduction lower gap 13 on the substrate B of an element. Then one resist part Ra is formed by exposure and development and the corner part at the upper part of the end surface is hardened after made smooth by a resist flow. Resist Rn is newly applied, and then cut by exposure and development to form the other resist part Rb. The other resist part Rb also has the corner part at the upper part on the end surface hardened after being made smooth by a resist flow. Lastly, a couple of leads are formed by plasma etching. The resist parts Ra and Rb are formed independently, so that distance between the resist parts Ra and Rb does not depend upon the exposure resolution of the resist and then the distance (between the couple of leads) can be made extremely small.
