Title: Semiconductor device
Inventor: SAITO TSUTOMU
IPC: H01L21/314
Filed: 1985-11-14
Abstract: PURPOSE:To prevent a high melting point metal from decreasing in its insulation due to diffusion in an interlayer insulating film due to high temperature treatment by interposing another insulating film having a function for stopping the diffusion of the metal between electrode wirings made of high melting point metal silicide and the insulating film of a silicon dioxide film covering on the wirings. CONSTITUTION:An Si3N4 film 8 having approx. 2,000Angstrom  of thickness is interposed as a high melting point metal diffusion stopping insulating layer between a metal silicide (high melting point metal silicide) such as SiO2 interlayer insulating films 9 vapor-phase grown on WSi2 gate electrode wirings 5 or a PSG interlayer insulating films. Since the layer 8 does not contain oxygen atom, it does not ionize the high melting point metal such as W by reacting with metal silicide, i.e., WSi2 at 1,100 deg.C or lower. Accordingly, since the metal, i.e., W is not diffused in the film 9, the insulation of the film 9 is sufficiently secured.

Title: Method for fixing lens sheet
Inventor: GOTO MASAHIRO
IPC: G02B7/00
Filed: 1988-10-11
Abstract: PURPOSE:To prevent floating of lens sheets from each other by partially or fully bending the lens sheets so that tension can be applied to the lens sheet arranged on the convex side and compressive force can be applied to the lens sheet on the concaves side. CONSTITUTION:A lenticular lens sheet 21 is bent with compressive force P applied by means of a frame 31 supporting a screen 2, with the frame 31 being smaller in size than the lens sheet 21. Then tension T is applied to a flexible Fresnel lens sheet 22 with a spring 32. When the lens sheets 21 and 22 are fixed in such way, the light transmissive screen 2 is bent, because the compressive force P is applied to the sheet 21 and the tension T is applied to the sheet 22. Namely, the sheets 21 and 22 are forcibly pressed against each other so that force F can be applied inward from both surfaces. Therefore, floating of the lens sheets 21 and 22 from each other can be prevented, even when one of the lens sheets 21 and 22 is flexible.

Title: Motor provided with thermal protector
Inventor: SAITO MAKOTO
IPC: H02K11/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent a motor from starting spontaneously once a bimetal is actuated, by bringing a heating resistor into contact with the bimetal, which, when the internal parts of the motor generate heat, is actuated by the generated heat. SOLUTION: If a coil 28 in a motor 26 is heated due to some trouble, the bimetal 23 in a thermal protector 20 is actuated by the heat. As a result, terminals 22, 24 are opening to interrupt power supply to the motor 26, which is then stopped. When the terminals 22, 24 have been opened, a heating resistor 25 in the thermal protector 20 starts heating. The shape of the bimetal 23 is maintained by the heating of the heating resistor 25 to prevent the terminals 22, 24 from being brought into contact with each other. Even if the temperature of the coil 28 in the motor 26 is lowered due to the interruption of power supply by the thermal protector 20, therefore, the terminals 22, 24 will not be brought into contact with each other and thus the motor 26 will not start spontaneously.

IPC: H01L21/205
Filed: 1989-09-29
Abstract: PURPOSE:To enhance the quality and reliability by a method wherein coating layers comprising electrically insulating material and having multiple through holes are formed on a semiconductor substrate while multiple insulating insular parts are formed in the through holes and then a semiconductor layer is vapor- deposited as if encircling the insular parts. CONSTITUTION:Coating layers 16, 17 comprising electrically insulating material and having multiple through holes 14 are formed on a semiconductor substrate 12 while insular parts 16 are formed in the respective through holes 14. Then, a semiconductor layer is vapor-deposited as if encircling the insular parts 16. However, the semiconductor layer on the insular parts 16 is not a layer deposited in the vertical direction to the surface of the semiconductor substrate 12 but another layer deposited in the horizontal direction from a vertically deposited layer. Such a semiconductor layer deposited in the horizontal direction will not be affected at all by any misfit transposition occurred on the interface between the semiconductor substrate 12 and the semiconductor layer so as to be provided with the extremely excellent crystallizability. Through these procedures, the quality and reliability of the title semiconductor device can notably be enhanced.

Filed: 1988-10-12
Abstract: PURPOSE:To make it possible to improve interpolation accuracy and to improve response scanning speed by arranging a second index scale on the opposite side of a first index scale with a main scale in-between. CONSTITUTION:An index scale 34 is arranged on the opposite side of an index scale 18 with a main scale 14 in-between. Secondary lattices 36 (36a-36d) as reference-light passing windows are formed. In DC-level detecting photodetectors 38 (38a'-38d'), light passing a main lattice 16 and the windows 36 undergoes optoelectronic transducing operation. The DC level fluctuations of detected displacement signals (a)-(d) obtained in displacement detecting photodetectors 22 (22a-22d) are corrected by using detected DC level signals a'-d' obtained in the photodetectors 38. Two-phase detected signals (a+a')-(c+c') and (b+b')-(d+d') are formed in a signal processing circuit 40 based on the outputs (a)-(d) and a'-d'. The amplitude signals in said two-phase detected signals are fluctuated, but the DC component becomes constant. Therefore, the stable detected signals are obtained, and highly accurate interpolation division can be performed and the highly accurate measured signals can be obtained.

Abstract: PURPOSE: To obtain a power conversion apparatus which prevents a change in a neutral-point voltage from being caused and which prevents an element from being broken down by installing DC power-supply devices which reversibly supply DC electric power in such a way that link voltages for respective capacitors become prescribed values. CONSTITUTION: In a neutral-point clamp inverter 100 at three or more levels, DC power supply devices 103 are connected individually to respective capacitors 102 which are installed to correspond to neutral points, positive pole sides and negative pole sides according to the levels. Then, currents which have been made reversible in such a way that voltages of the respective capacitors 102 are always kept at prescribed values are supplied from the DC power supply devices 103. Thereby, it is possible to restrain a change in voltages in the respective neutral points corresponding to the levels. Consequently, there is no fear that a switching element is broken down due to an overvoltage, a voltage margin can be made small, and a larger output can be obtained.  In addition, when a power conversion apparatus is controlled by an open-loop rotating machine, a change in a neutral-point voltage can be avoided, and it is possible to restrain vibrations from being generated.
