Patent JP-S56118348-A (JP)
Title: Semiconductor device
Inventor: SHIRAI KAZUNARI
IPC: H01L27/06
Filed: 1980-02-22
Abstract: PURPOSE:To regulate effectively the threshold voltage of an FET, by forming a thicker gate oxidized film on the interface part of the field oxidized film and the device region than on other parts. CONSTITUTION:A channel stopper and a field oxidized film 6 are formed normally on a P type Si substrate 1 using Si3N4 mask, and a gate oxidized film 7 with a thickness of about 600Angstrom  is formed and an opening is formed thereto. Further, it is covered with a gate oxidized film 8 with a thickness of about 400Angstrom  and a polycrystalline Si 9 is stacked. Thereafter a gate electrode 9 and the gate oxidized film 8 are formed by etching and an N layer 10 is formed by As ions implantation and heat treatment. Then an SiO2 11 and PSG12 is stacked and an electrode window is opened. After smoothing the end portions by glass flow, an Al electrode 14 is formed. With such an arrangement, because the SiO2 is formed thickly on the interface end part of the P<+> channel stopper and the N layer 10, electric field concentration is eased and the hot carrier is prevented from taking place, thus resulting in the more effective regulation of the threshold voltage of the FET.

Title: Lens driving device
Inventor: YAMADA MINORU
IPC: G03B11/04
Filed: 1985-02-06
Abstract: PURPOSE:To move a movable lens to a draw-out position or collapsible barrel position without slanting its optical axis by moving one operating member by more than the movement length of a lens and allowing the operating member to operate so that is overruns at both end positions of the lens. CONSTITUTION:When a driving pin 9a moves forth in the direction of the optical axis through the rotation of a motor, an interlocking shaft 6a is rotated clockwise through a lever 6 to drive a pin 2c forward in the direction of the optical axis through the elastic operation of a spring 7a while driving a pin 2b forward in the same direction through the elastic operation of a spring 8a, so the movable lens unit 2 is drawn out in the direction of the optical axis. The pins 2b and 2c operates until the movable lens unit 2 stops when the front surface of its projection piece 2a abuts on the rear end surface of the mount 1a of a front plate 1, and the stroke of a driving pin 9a which exceeds it, i.e. overrun of the interlocking shaft 6a is absorbed by the elastic deformation of the springs 7a and 7b.

IPC: G09F9/00
Filed: 1989-01-31
Abstract: PURPOSE:To decide a number consisting of seven segments with the smallest number of windows by comparing combinations of the numbers of half segments in different windows corresponding to numbers 0 - 9. CONSTITUTION:The combinations of the numbers of half segments in a window A which covers all the segments, a window B which covers halves of two right upper segments, and a window C which covers halves of two left lower segments are compared corresponding to the numbers 0 - 9. Therefore, when three areas which cover all the seven segments, two right upper halves, and two right lower halves are divided, the numbers of the number of picture elements in the respective areas correspond to the numbers 0 - 9 and the same number is never represented by the combination of >=2 numbers of picture elements. Consequently, the numbers 0 - 9 can be identified only by using the three windows.

IPC: G02F1/133
Filed: 1986-02-06
Abstract: PURPOSE:To operate an optical shutter stably by using a monostable ferroelectric liquid crystal cell where liquid crystal molecules are arranged in one direction when a voltage is not applied, and driving said cell with an AC. CONSTITUTION:Orientation control films 3a and 3b are provided to not only arrange liquid crystal molecules in parallel with substrates and in one direction for non-application of the voltage but set liquid crystal molecules to the monostable state where they respond to only the electric field of one polarity. After such orientating treatment, a spacer like organic beads or alumina particles is interposed between substrates so that substrates are held in parallel with each other and with a certain gap between them, and peripheral parts are fixed with a seal agent 5 to obtain a cell. The voltage applied to the cell by a driving circuit 7 is so alternated that the integral value of time is '0', and only its one polarity contributes to the change of the arrangement structure of the liquid crystal, and as the result, the light transmittance is changed.

Abstract: PURPOSE:To prevent as much as possible the reduction of the water wheel efficiency by providing a vane wheel with vane blades in the shape of an aerofoil cross section and by maintaining constant flow velocity when the effective head is small. CONSTITUTION:Since a vane wheel 4 comprises vane blade 7, 7... having a cross section in the shape of an aerofoil, it is rotated in the direction of ''B'' with a speed larger than the velocity ''V'' of the water flowing into an intermediate piping passage 3 as is evident from the aerofoil theory. As the vane wheel 4 is constituted by blades 7, 7... having an aerofoil like cross section along the water flow direction, the reduction of the water wheel efficiency can be prevented even when the effective head is small if constant water flow velocity could be maintained.
