Title: High-breakdown-strength mis transistor
Inventor: TANAKA SOICHIRO
IPC: H01L29/78
Filed: 1990-01-31
Abstract: PURPOSE:To enhance a breakdown strength by a method wherein, in a high- breakdown-strength MIS transistor, a part around an interconnection contact part in a drain region is set to a low impurity concentration. CONSTITUTION:Since a part around an interconnection contact part in a drain region 6 is set to a low impurity concentration, a depletion region 10 of a large width is formed in a junction part of a part 6a around the interconnection contact part at the low impurity concentration to a semiconductor substrate 1. The region of the depletion layer formed in the junction part of the drain region 6 to the semiconductor substrate 1 is expanded, and a drain electric field is relaxed by this expanded portion. For example, the surface of a semiconductor substrate 1 is thermally oxidized selectively, a field insulating film 2 is formed, and an interelement isolation operation and an innerelement isolation are executed. Simultaneously with the operations, n-type impurities and p-type impurities which have been ion-implanted in advance into the semiconductor substrate 1 are diffused, and, e.g. an n<+> type channel stop region 3 and a p<-> type low-impurity concentration part 6a are formed at the lower side of the field insulating film 2.

Inventor: UENO ICHIRO
IPC: G11B11/105
Filed: 1990-01-31
Abstract: PURPOSE:To record/reproduce/erase information at a high speed with high accuracy by adjacently or closely arranging the side surfaces of two magnets to each other, whose magnetization directions are vertical to the surface of a magneto-optical film along an anisotropic axis direction and are opposite to each other. CONSTITUTION:A bias magnet 4 is constituted of the prism-like magnets 5A and 5B whose magnetization directions are opposite to each other and an iron yoke 6. The magnets 5A and 5B are stuck to the lower surface of the yoke 6 in a state where their inner side surfaces are adjacent to each other to be stuck, and positioned above light spots 13a and 13b respectively. In the magneto- optical film 2b below the magnets 5A and 5B, bias magnetic field whose pitch is small is formed to be in the vertical direction to the surface of the film 2b and in the opposite direction to each other. Thus, the spots 13a, 13b and 13c are respectively used for erasion, recording and reproducing, thereby accomplishing the high-speed and high-accuracy recording/reproducing/erasion.

Title: Cutter fastening device
Inventor: HOSONO HIDEJI
IPC: B23Q3/12
Filed: 1986-02-03
Abstract: PURPOSE:To make it possible to decrease the deflection of the front end of a cutter body, by making the center axis of the fitting section formed in an adapter, eccentric from the center axis of a drive shaft so that the eccentricity if the cutter body is decreased. CONSTITUTION:A drive shaft 1 and a adapter 2 may be attached and separated from each other by means of a bolt in such a condition that the concave fitting section 2a of the adapter 2 is fitted in a concave fitting part 1a in a drive shaft. Further, the center axis C1 of a through-hole A2 in the adapter 1 is eccentric from the center axis C2 of a through-hole A3 in a cutter body 3 by a distance e1. Accordingly, the amount of deflection of inside diameter of a guide bushing 3e is measured by use of a dial gage 5 while the drive shaft is slowly rotated. When the amount of deflection of the guide bushing 3e is greater than a predetermined value, the rotation of the drive shaft 1 is stopped and a bolt is loosened, and if the cutter body 3 is rotated with respect to the adapter 2 the eccentricity e of the cutter body 3 is made to be small, thereby it is possible to reduce the deflection of the guide bushing 3e.

Title: Thermal transfer printing device
Inventor: OYA SEIJIRO
IPC: B41J15/04
Filed: 1989-01-31
Abstract: PURPOSE:To dispense with a travel route for printing paper originating from outside the subject device and make possible the prevention of developed defects such as paper folds or jam by providing a head retraction mechanism which feeds and discharges roll paper due to its own rotation and at the same time, moves a printing head in response to a change in the diameter of the roll paper. CONSTITUTION:In printing data under a thermal transfer system, almost no impact generates during printing, so that it is possible to allow roll paper to take the place of a platen. As a progress is made in printing, the diameter of roll paper 12 becomes smaller gradually and the distance between the roll paper 12 and a printing head 13 becomes wider gradually. Then a head retraction mechanism 1 is adjusted so that its pressure is constantly maintained at a specified level. The head retraction mechanism 1 rotates a motor 2 as the diameter of the roll paper 12 becomes smaller gradually. Then a motor 2 is allowed to rotate and a drive force is transmitted to gear A3. At the same time, gear B4 rotates a cam 5 to transfer a pressing force to a transfer spring 7. Thus, the printing head 13 is allowed to come in contact with the roll paper 12 so that the pressure is not applied higher than a specified pressure.

Title: Package for photographic printing paper
Inventor: HERUMUUTO BUREKURINSUKI
IPC: G03C3/00
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To give tension to the material and to prevent inward collapse of flanges by applying a synthetic polymer layer by extruding on the one side of a paper base. SOLUTION: This package has annular flanges in the width direction and an extended sheet for packaging which is to be welded to the flanges. The one end of the extended sheet is connected to the head point of a paper roll and the other is free. In this case, for example, a synthetic polymer layer having 20-60μm thickness is applied on the paper base of the flange by extrusion forming. This layer is preferably made of a polyethylene and gives tension to the material and prevents inward collapse of the flange. The plastic layer is formed to 30-50μm thickness by using a HDPE (high density polyethylene). To prevent the polymer layer from fusing when the flange and the extended sheet for packaging are welded, a heat-resistant paint is applied on the polymer layer.

IPC: G11B5/02
Filed: 1994-01-21
Abstract: PURPOSE:To miniaturize the whole device by connecting diodes in series with two field coils respectively and connecting capacitors in parallel with respective both field coils. CONSTITUTION:A recording head is composed of two field coils L1, L2 with a cores in common and field coils L1, L2 are driven by using switching elements Q1, Q2 by arranging generated magnetic fields of both field coils L1, L2 to be opposed each other. A resonance phenomenon is generated between field coils L1, L2 and an interwire capacitance by providing diodes D1, D2 in series with field coils L1, L2 respectively. The half of the resonance period of this resonance circuit becomes the inversion time of a head current. Thus, an operating voltage and power consumption can be reduced as much as possible by setting the resonance period matching with the allowable inversion time of the head current while providing capacitors C1, C2 in parallel with field coils L1, L2.
