Title: Thin film semiconductor element and manufacture thereof
Inventor: IKEDA NAOKI
IPC: G02F1/136
Filed: 1989-05-26
Abstract: PURPOSE:To prevent an OFF-current from increasing at the irradiation of a thin film semiconductor with back light so as to improve it in contrast ratio by a method wherein the part of a semiconductor layer formed of amorphous silicon other than a channel part is made low in hydrogen content. CONSTITUTION:A part 23, at least, of a semiconductor layer A formed of amorphous silicon other than a channel part 21 is made low in hydrogen content. Therefore, the part 23 excluding the channel part 21 is made to increase in dangling bond density owing to the reduction of H atoms bonded to dangling bonds, and the peak of the state density concerned is enhanced with the increase of localized levels in number. Therefore, excited carriers occurred when a current and holes are excited at irradiation with back light are apt to be trapped by localized levels or recombined, so that the excited carriers which reach to a conduction band are decreased. By this setup, an OFF-current can be prevented from increasing at irradiation with back light and a contrast ratio can be improved.

Title: Recovery of coal from raw coal slurry
Inventor: NAGATA KENICHI
IPC: C10L5/00
Filed: 1979-10-16
Abstract: PURPOSE: To recover dried coal having low water content from the slurry of raw coal, in high efficiency and dehydration efficiency, by separating the raw coal slurry into coarse coal slurry and fine powder slurry, dehydrating the former slurry as it is, while subjecting the latter slurry to concentration, addition of mineral oil, granulation and dehydration.  
     CONSTITUTION: The slurry of raw coal is separated into the coarse coal slurry (the diameters of coal particles are 1W30mm) and the fine powder slurry (≤1mm in diameter) with a fine powder separator 6 and/or a storage tank 8. The coarse coal slurry is dehydrated with a dehydrator 10 to recover the coarse coal 11. On the other hand, the fine powder slurry is concentrated to the concentration of about 30wt% in the tank 14, added with 5W20wt% of mineral oil 17, granulated, and dehydrated with the dehydrator 10' to recover the granulated coal 19.  
     EFFECT: The process is economical because the necessary amount of the mineral oil is small, and the oil can be recycled.

Title: Rotary valve mechanism for internal combustion engine
Inventor: ASAKA URATAROU
IPC: F01L7/02
Filed: 1979-10-16
Abstract: PURPOSE: To improve the efficiency for drawing and charging mixture into combustion chambers of an internal combustion engine, by forming in the body of a rotary valve an inlet port and an outlet port having different opening areas and located different distances from the axis of the rotary valve, and thereby producing a restricting function by the difference of the centrifugal force produced when the rotary valve is rotated.  
     CONSTITUTION: An intake passage A is formed axially of the body of a cylindrical rotary valve 6, in the manner that one end of the intake passage A is connected selectively to an inlet port D formed radially of the rotary valve and the other end is connected selectively to an outlet port F. Here, the opening area of the inlet port is made smaller than that of the outlet port. With such an arrangement, the centrifugal force produced at the outlet port by the rotation of valve body 6 can be made greater than that produced at the inlet port. By the difference of this centrifugal force, the velocity of mixture flow into combustion chamber 5c through the outlet port F can be made high, so that a large amount of intake air is introduced into the combustion chamber 5c. Further, since the fact that the outlet port F has a large area results in increasing of mixture drawing force, intake air drawing and charging efficiency can be improved.

Title: Normalizing system for picture density gradient
Inventor: YAMAMOTO EIICHIROU
IPC: G06T7/60
Filed: 1984-06-28
Abstract: PURPOSE:To quickly normalize the density gradient of an inputted picture, by adding the direction of density gradient of each picture to each other by weighting them in accordance with the scale of the gradient and averaging the density over the whole picture elements. CONSTITUTION:Data in the vicinity of a point (X, Y) are read out from an input picture image memory 6 and differentiated values GX and GY in X and Y directions are calculated at X-direction and Y-direction differentiation circuits 12 and 13 and, moreover, the scale and direction of the density gradient of picture elements are calculated by using the differentiated values GX and GY at arithmetic circuits 14 and 15. Then a multiplier 16 weights the scale of the density gradient in the direction of the density gradient of one picture element and an adder 18 adds the weighted gradient directions to each other. The added sum is held in a register 20. The weighting values of all picture elements are also added to each other by another adder 17 and held in another register 19. An arithmetic circuit 21 finds the mean value of the directions of the density gradients of the inputted picture by dividing the value of the register 20 by the value of the register 19, and outputs the mean value as the rotating quantity of the inputted picture.

Title: Fluorescent type liquid crystal display device
Inventor: FUNADA FUMIAKI
IPC: G02F1/13
Filed: 1977-11-07
Abstract: PURPOSE: To let display part emit fluorescence by applying stimulus fields such as electric fields or the like to the thin layer of the liquid crystal comprising dissolving of organic fluorescent material thereby putting the same in a light scattering state.  
     CONSTITUTION: Liquid crystal which is added with organic fluorescent material such as Rhodamine 6G is held between two sheets of substrates such as glass provided with transparent electrodes. When no voltage is applied from a voltage generator 9 to the transparent electrodes, the organic fluorescent material having absorbed excitation light hυ 1  from the surroundings emits fluorescence hυ 2 , but the fluorescence is hardly integrated in the layer thickness direction of the thin liquid crystal. On the other hand, the fluorescence is integrated in the direction orthogonal to the layer thickness but the liquid crystal is optically evenly oriented and therefore the fluorescence is taken in the liquid crystal and is not released to the display side, thus giving a dark display. When a voltage is applied, the centers 10 having light refractiveness or light scattering characteristic are produced in the liquid crystal and the fluorescence hυ 2  is released to the display side, forming a bright display.

Title: Switch valve
Inventor: ANDOU HIDEO
IPC: F16K31/40
Filed: 1980-09-29
Abstract: PURPOSE: To provide a small-sized switch valve without an inferior effect given when an exhaust gas is throttled, by disposing spring-loaded resilient pistons at the both ends of a vacant spool and forcing their external ends to contact the interior face of a valve body, thereby keeping the spool in a neutral position.

Title: Production of semiconductor device
Inventor: ENDOU SHIGEKAZU
IPC: H01L21/306
Filed: 1977-11-09
Abstract: PURPOSE: To reduce side etching and selectively etch insulation film by producing defects through ion implantation prior to etching of the insulation film of a semiconductor and controlling the rate of etching with the defect thus produced.  
     CONSTITUTION: After silicon dioxide 2 is grown on monocrystalline silicon 1, an etching mask pattern is formed with photo resist 3. Next, heavy neutral atom ions 4 are implanted to the extent of not allowing the ions to arrive at the silicon, thereby beforehand producing defects 5 in the ion implanted region. When this sample is wet-etched or plasma- etched after the ion implantation, the silicon dioxide is etched at a rate of etching faster than before, as a result of which even if the silicon dioxide is slightly thick, the etching of the silicon dioxide of less side etching may be realized.

Elements 102-194 are formed by a process such as vapor deposition, photolithography, etching, etc. with their track width directions set parallel to the magnetization unfacilitating axis direction 601. In this case, the magnetization facilitating axis direction 602 of the layer 302 is set in parallel to the element accumulating surface and at the same time rectangular to the track width direction. A protecting plate 105 made of nonmagnetic glass, ceramics, etc. is adhered to the upper part of the element, and then rubbing surfaces 106a and 106b of a medium are polished. Thus a magnetic head is obtained.
