Title: Motion pattern generator for transfer feeder
Inventor: DOI IKUMA
IPC: B21D43/05
Filed: 1989-05-02
Abstract: PURPOSE:To improve a production speed by making decision as to whether formed motion patterns can be operated in a servo driving system of a transfer feeder or not by a deciding means. CONSTITUTION:Storage buffers 55, 80 temporarily store pattern forming data and servo system capacity data, etc., when the above-mentioned data, etc., are inputted to a keyboard 10. A computing element 60 computes and forms the motion patterns of the respective axes of the feeders by using the pattern forming data. The servo system capacity data is inputted to a deciding device 70. The deciding device 70 makes decision as to whether the motion patterns of the respective feed axes formed by the computing element 60 on the bases of the above-mentioned data can be operated by the servo driving system or not. The patterns are stored into a memory 90 if a yes is decided. An error code is displayed on a display device 15 if a no is decided. The optimum motion patterns are selected from the memory 90 and are used at the time of operation.

IPC: H01L21/331
Filed: 1982-06-30
Abstract: PURPOSE:To improve the manufacturing yield and the reliability of a semiconductor device by forming by self-aligning inner and outer bases by utilizing the difference of etching rate of KOH between a polysilicon doped in P<+> type and a polysilicon not doped, and enabling to readily remove a polysilicon layer used to form a window used for diffusion to form the inner base. CONSTITUTION:A photoresist film 27 is removed with KOH, and polysilicon which is disposed under the film and not doped is removed. Then, polysilicon is thermally nitrided to form a nitrided film 26a, an oxidized film 25 is etched with the film 26a as a mask, thereby forming windows E, B. Subsequently, the film 26a is removed with phosphoric acid. Thereafter, a polysilicon layer 27 which is not doped is grown on the overall surface, an inner base 28 and a base contact 29 are formed by through diffusion using the windows E, B through the layer 27, and an emitter 30 is formed by double diffusion using the same window E. In other words, since the emitter diffusion is performed without any alteration of the pattern as it is from the window E formed with the base 28, a possibility of displacing the position can be entirely eliminated.

Abstract: PURPOSE:To permit the cooling for a car interior independent from an engine and batteries by operating a pump for allowing coolant to circulate between an evaporator and a radiator by the electric power of solar batteries and improving the heat radiation effect of the radiator through the dripping of water by a cooling means. CONSTITUTION:Coolant is pumped-up from a liquid reservoir 4 by a pump 5 and sent into an evaporator 1, and jetted-out in mist form from a nozzle, and the coolant in mist form robs heat from the air in car interior and is evaporated, and therefore, the air on the periphery of the evaporator 1 which is cooled by the heat exchange with the coolant is allowed to circulate in the car interior by a fan 6, and the car interior is cooled. Then, the coolant evaporated in the evaporator 1 passes through a heat pipe 3 and disperses into a radiator 2, and cold wind is blown into the radiator 2 by a fan 7 and cools the evaporated coolant. Therefore, the cooled coolant liquefies and is gathered into the cold liquid reservoir 4, and when the liquefaction of the coolant proceeds, the vapor pressure on the radiator 2 side lowers, and the evaporated coolant easily flows into the radiator 2, and the evaporation of coolant is accelerated with the reduction of the vapor pressure, and the heat radiation effect can be improved.

Title: Magnetic head for vertical magnetic recording and reproduction
Inventor: AOYAMA AKIRA
IPC: G11B5/127
Filed: 1980-08-20
Abstract: PURPOSE:To offer a magnetic head capable of both-sided recording by using residual magnetization perpendicular to the magnetic film surface of a recording medium. CONSTITUTION:Ceramic 22 is formed by uniting a recording main magnetic pole 19a and a reverse-side recording auxiliary magnetic pole 20b, and a top-side recording auxiliary magnetic pole 20a and a reverse-side recording main magnetic pole 19b on surfaces respectively. A thin Co-Cr magnetic film 18 has an easy-to-magnetize axis vertically, and a permalloy magnetic thin film 17 has easiness of magnetization horizontally, so magnetic flux runs as shown by an arrow while components running in a recording medium horizontally are much less. The auxiliary magnetic pole comes in contact with the medium with wide area, a magnetic field is small and never exceeds coercive force. Therefore, dresidual magnetization never remains. The residual magnetization is left by the main magnetic pole which comes into contact with a magnetic thin film 18 with extremely narrow area to perform recording.
