Filed: 1990-02-28
Abstract: PURPOSE:To remarkably decrease the area of an electrodeposition terminal part required for electrodeposition by forming a terminal part protective film by using the electrodeposition terminal of a one-color portion in common with a liquid crystal driving terminal part. CONSTITUTION:A liquid crystal driving terminal part of a transparent electrode 2 on a glass substrate 1 is extended so as to become uneven by a two-color portion and formed to a first color electrodeposition terminal 2A and a second color electrodeposition terminal 2B, and also, the liquid crystal driving terminal part is covered by using a protecting photoresist 3.

Title: Oil-filled bushing
Inventor: KOBAYASHI TADAFUMI
IPC: H01B17/34
Filed: 1992-03-05
Abstract: PURPOSE:To prevent a large quantity leak of insulation oil filled inside an oil-filled electric appliance even when an upper bushing or lower bushing is broken or removed by providing a closing means comprising a stopper, a partition plate, and a support metal. CONSTITUTION:An oil-filled bushing is installed horizontal to a lead part of an oil-filled electric appliance by fixing an edge of an installation flange 3. In this case, if the oil-filled bushing is in a normal condition, a center conductor 1 and a capacitor cone 2 are at a center position of a cylinder part of the flange 3, and an oil hole of a stopper 22, an oil hole of a partition plate 21, and an oil hole of a support metal 23 communicate with each other, so insulation oil filled inside the oil-filled bushing makes convection through the oil holes. When an upper bushing 4 or a lower bushing 5 is broken or removed, for example, the plate 21 drops through a recessed part of an oval form provided in the stopper 22 to stop through a closing means comprising the stopper 22, plate 21, and support metal 23. A large quantity leak of insulation oil filled inside the appliance can thus be prevented.

Title: Switching frequency division circuit
Inventor: MIZUGUCHI HIROSHI
IPC: H03K23/66
Filed: 1982-03-25
Abstract: PURPOSE:To set the frequency dividing ratio to 1/3:1/1.5:1/1, by using a double- multiplication circuit generating an output pulse at a leading edge and a trailing edge of an input pulse and an N-scale frequency-divider to which the output  pulse of the double-multiplication circuit is applied. CONSTITUTION:A clock pulse shaping the waveform of an output signal of, e.g., a frequency generator is applied to an input terminal A. NAND gates 1, 2 and 3 form the 1st pulse generating circuit 100, NAND gates 4, 5, 6 form the 2nd pulse generating circuit 200, and the pulse generating circuits 100 and 200, and an NAND gate 7 form the double-multiplication circuit 300. An NAND gate 7 to which the output of the NAND gate 7 and of flip-flops 8, 9 is applied, forms a 3-scale frequency divider 400. When the level of an input terminal B is ''0'', a switching frequency-divider acts like a 1/3-freqency divider, but when the level of the input terminal B goes to ''1'', the output frequency is doubled and the divider acts as a 1/1.5-frequency divider.

IPC: B62D6/00
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To easily prevent load collapse and the lack of vehicle stability caused by a sharp turn at high lift height by making a steering wheel heavy to suppress the sharp turn of a vehicle when the vehicle is in an unstable state at high lift height. SOLUTION: When the operation of a steering wheel 13 is detected by a signal from a torque sensor 29, a controller 33 drives a PS motor 21 to rotatory- drive a PS pump 22, thereby feeding operating oil to a PS valve 23 to reduce the operating force of the steering wheel 13. The weight of the steering wheel 13 is determined by the quantity of oil fed from the PS pump 22 to the PS valve 23. In this case, the controller 33 grasps present lift height and load by input signals from lift height sensors 30, 31 and a load sensor 32 and obtains the set rotating speed of the PS motor 21, referring to a map set to make rotating speed lower as the center-of-gravity height is higher from the data of lift height and load.

The thermal analysis of the PET film performed previously by a differential scanning calorimeter(DEC) shows that the fusion starting temperature is 210 deg.C and the heat absorption peak temperature in fusion is 260 deg.C. The PET film is thermally contact-bonded at 210-260 deg.C using a heat contact-bonding roll 3 from a viewpoint of the specific temperature of the resin, and then is pressed again at a specified face pressure using a silicone rubber-lined repressure roll 5 after the heating-up of the PET film at 250 deg.C or higher.

IPC: G11B20/12
Filed: 1993-02-15
Abstract: PURPOSE: To provide a method and a means for precisely reading head positioning information in an off track state without increasing an error rate. CONSTITUTION: Fixed block system address head positioning information 203 which can be read in the off track state without increasing the error rate is provided in a data recording disk file. Since head positioning information 203 has identification information 201, the moving position of a recording head in the radius direction or the circumference direction is indicated. Both or one of identification information 201 or error processing information 205 is arranged in offsetting position in the circumference direction on the data storage disk at every adjacent track. Thus, the interference of the adjacent tracks is removed and information is arranged in an overlapped position in the radius direction on the data storage device by extending it in the adjacent tracks. Thus, information can completely be read even if the recording head is in the off track state.

Filed: 1988-03-02
Abstract: PURPOSE:To prevent the formation of a metallic film on the unnecessary parts of a semiconductor, such as side faces and the rear, by coating a semiconductor substrate with a material consisting of insulating material at the time of forming a metallic film on the surface of the semiconductor substrate by a selective CVD method. CONSTITUTION:A semiconductor substrate 8 in which an insulating film 6 is previously formed on the surface and further contact holes 5 are formed in the surface by means of a photoengraving technique is set in a reaction chamber 2 in a state where the side faces and base of the semiconductor substrate 8 are enclosed by a substrate-coating means 4 consisting of insulating material. Then, a reactant gas, such as tungsten hexafluoride, is supplied via a reaction head 1, and a tungsten film 7 is deposited in the contact holes 5 by a CVD method (a chemical vapor deposition method). At this time, since the deposition of tungsten on the side faces and base of the semiconductor substrate 8 is prevented because of the above-mentioned coating with the insulating material, the metallic film 7 of tungsten, etc., can be formed on the semiconductor substrate in a short time.

IPC: F24F13/14
Filed: 1985-03-12
Abstract: PURPOSE:To obtain an expanded flow without almost increasing a resistance with respect to the flow by providing a pair of opposite expanded walls in the vicinity of the outlet of a fluid passage, and providing a pair of direction control vanes in the vicinities of the walls to direct the downstream side slightly outwardly. CONSTITUTION:In the blow-off port of a hot air space heater or a blower, a pair of outwardly expanding walls 7 and 7 are provided in the vicinity of the outlet of a fluid passage 6, and a pair of direction control vanes 9 and 9 having rotary shafts 8 and 8 are provided in the vicinities of the walls 7 and 7. An outward deflection angle thetaF of a fluid is not determined by the angle of direction control vanes 9 and 9 but is substantially determined by the divergent angle of the outward expanding walls 7 and 7, and direction vanes 9 and 9 create changes for the adherence of the flow to the outward expanding walls 7 and 7. Accordingly, it is made possible to obtain a large divergent angle determined by the substantially outwardly expanding walls by suppressing the angle thetaW of the direction control vanes 9 and 9 to a small value while suppressing the resistance with respect to a fluid to a small value.
