IPC: G09F9/35
Filed: 1988-02-04
Abstract: PURPOSE:To reduce the number of photoetching processes to reduce the production cost of an active matrix substrate by changing the order of photoetching processes for formation of an electrode film and a semiconductor film to use a pattern for photoetching in common. CONSTITUTION:After a conductive film 2 is stuck throughout the surface of an insulating substrate 1, a photomask having a first pattern is used to form a three-layered semiconductor film 6. A photomask having a second pattern is used to perform photoetching, thereby forming a photoresist 42. Then, the conductive film 2 is separated to a picture element electrode 10 and a scanning electrode 20. Next, the photoresist 42 and an insulating film 7 on it are removed together after the insulating film 7 is stuck throughout the surface, and a connection film 8 is formed by photoetching with a photomask having a third pattern after the connection film 8 is stuck throughout the surface. Thus, the number of times of photoetching is reduced to three.

Title: Controller for engine driven generator in electric automobile
Inventor: KOTANI TAKESHI
IPC: B60L50/10
Filed: 1993-02-15
Abstract: PURPOSE:To enhance specific fuel consumption of engine under low emission by controlling the air-fuel ratio close to the lean limit under a state where the engine load does not fluctuate. CONSTITUTION:An engine load fluctuation suppressing means F controls the field current of a generator B to a constant level when the fluctuation of load C on the generator B is substantially zero and the generator B is generating power thus bringing about a state where the fluctuation of power generated from the generator B is substantially equal to the fluctuation of torque of an engine A. A generated power detecting means G detects power generated from the generator B under that state. An operating means H determines an average power for a predetermined time and fluctuation thereof based on the power thus generated. When the average power is close to a target value, an air-fuel ratio control means I controls the air-fuel ratio of the engine A close to a lean limit depending on the fluctuation of generated power, thus enhancing the specific fuel consumption of the engine A under low emission state.

Title: Reversal controlling method for table and device thereof
Inventor: URANISHI WATARU
IPC: B23Q1/00
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To suppress a shock due to a reversal if a table feeding speed is high so as to smoothly carry out a reversing action. SOLUTION: When hydraulic cylinders 17R, 17L are controlled by means of a servo valve so as to move a table 5, a regulating means carries out regulation so that a clockwise reversal speed increasing/reducing time TR and a counterclockwise reversal speed increasing/reducing time TL are matched with a moving speed VT of a table 5 so as to control the servo valve. Therefore, a reversal of the table 5 is carried out at the speed increasing/reducing times TR, TL matching with the moving speed VT of the table 5 even if the table 5 moves at a high speed, so that a shock in the reversal can be reduced. For the regulating means, a three-way volume, by which the clockwise reversal speed increasing/reducing time TR and the counterclockwise reversal speed increasing/reducing time TL are set at the same time in compliance with the moving speed VT of the table 5, is effective.

Filed: 1987-02-06
Abstract: PURPOSE:To obtain a position specifying device suitable to a large-sized terminal equipment which needs to move a mouse to a specific position by pressing an operation button without moving the mousse and obtaining the same effect with the movement of the mouse. CONSTITUTION:The mouse position specifying device which moves the cursor on a display screen by the rotation of a ball 3 is so constituted as to provide the same effect by the depression of the operation button 21 without moving the mouse.

Abstract: PURPOSE:To obtain chip-shaped electronic parts equipped with an external electrode being high in corrosion resistance, in which electronic parts any non- uniform stress does not act on the body of the electronic parts at the time of forming or soldering the external electrode, by constituting the external electrode from a porous metal body impregnated with synthetic resin and from a metallic deposit formed on the outside of the porous metal body. CONSTITUTION:A ceramic sheet and conductive paste are alternately laminated and sintered to form an element assembly being an electronic parts body 2, and the conductive paste is applied to both ends of the element assembly to form an external electrode 1. Then, a silicone resin liquid is impregnated into the external electrode 1 and the impregnated silicone resin is hardened by heating. Subsequently, synthetic resin stuck on the surface of the external electrode 1 is eliminated and the external electrode 1 is electroplated. Thus, silicone resin 6 is impregnated into pores of the porous metal body 5 and a metallic deposit 7 is formed on the outside of the resin. Therefore, stress acting on the electronic parts body 1 is alleviated and a plating solution does not enter the external electrode 1.

IPC: B41M5/26
Filed: 1987-02-06
Abstract: PURPOSE:To enable a multicolor image to be transfer-recorded on a color- forming sheet coated with a color developer due to the heat given once from a thermal head, by using a thermal transfer sheet coated with microcapsules of Cyan, Magenta, and Yellow having color-forming temperatures different from each other in uniformly mixed states. CONSTITUTION:On a substrate 2-1 of a multicolor thermal transfer recording sheet 1, microcapsules 4 containing leuco dyes which color into Cyan, Magenta, and Yellow, 7, 9, 11, decoloring agents 6, 8, 10, and a solvent 12 are coated in uniformly mixed states. On the other hand, on a substrate 4-2 of a color- forming sheet 3, a color developer 13 is coated. These two paper sheets 1, 3 are in contact with each other with the respective coated surfaces opposed to each other. In this manner, since the microcapsules 4 of Cyan, Magenta, and Yellow independently form colors at different temperatures, a multicolor image can be recorded due to the heat given once only by controlling the temperature of a thermal head 15.

Title: Optical device equipped with mechanism for preventing vibration during transportation of copying machine
Inventor: YAMADA MAKOTO
IPC: G03G15/04
Filed: 1989-02-03
Abstract: PURPOSE:To protect a mirror unit from impact arising from vibration, etc., by allowing a turn preventing member to abut on a link body in a position in which a contact piece abuts on the highest part of a cam part. CONSTITUTION:A lens unit 51 is interlocked with the mirror unit 61 through the link body 71, and both units are fixed in their prescribed positions in response to a set object magnification. A lens stopper 100 prevents an L-shaped link 72 from turning clockwise at a magnification at which the contact piece 75 abuts on the cam surface 55c, but it does not interrupt the counterclockwise turning of the link 72. The optical device is transported with the contact piece 75 abutting on the cum surface 55c, that is, an unmagnified position. In such a way, the clockwise turning of the link body is prevented, whereby the contact piece fitted to one end of the link body in the unmagnified position is prevented from moving away from the cam part. Moreover, the vertical move of the mirror unit abutting on the link body is suppressed, and the mirror unit is protected from impact arising from vibration when it is transported.

Abstract: PURPOSE:To avoid abnormal deposition of a film deposited on a lower metal layer by a method wherein an overhanging part of an upper metal layer which is projected out of the lower metal layer is formed by etching and the overhanging part is made to hand down to cover the side surfaces of the lower metal layer. CONSTITUTION:A lower metal layer 3 is etched. At that time, a sufficiently overhanging part of an upper metal layer 2 which is projected out of the lower metal layer 3 is formed by taking the etching period 3-5 times of the ordinary one. For instance, if the thickness of the lower Al layer is 3,000Angstrom , conventional etching period is 30sec at the temperature 40 deg.C but, to the contrary, the etching is carried out for 1min 30sec - 3min under the same conditions and then photoresist 1 is removed. By forming the overhanging part of the upper metal layer 2 sufficiently, the overhanging part hangs down after the photoresist 1 is removed and forms tapered parts so as to cover the side surfaces of the lower metal layer 3.
