Patent JP-S59168226-A (JP)
Title: Phase-angle controlling apparatus
Inventor: TSUDA KIICHIROU
IPC: F02D1/18
Filed: 1983-03-11
Abstract: PURPOSE:To obtain a phase-angle controlling apparatus with ease and economically, by enabling to control the phase angle under the state that oil pressure is balanced with the force of a spring by setting a pressure corresponding to the phase angle in controlling the phase angle of a driving shaft and a driven shaft of a rotatable means used in a fuel injection timing controlling apparatus or the like. CONSTITUTION:When a pilot pressure is applied from a pressure setting means 110, pressure oil is passed through passages 12, 32, 66, 65, 63 and exerts a force to the right-side end face of a nozzle 8, so that the position by the nozzle 8 is determined under the state that the oil pressure is balanced with the force of a spring 7. At the same time, the pressure oil is carried to a cylinder 62 via passages 11, 31, 64 and turns a projection 2a clockwise by applying force to a plunger 5. Futther, pressure oil passed through a fixed restriction 9 is carried to a flapper 2b via an oil passage 82 and then carried back to a tank via an oil passage 13, etc. In this state, if the pilot pressure is raised, the nozzle 8 is moved to the left against the force of the spring 7 and the back pressure P in the nozzle 8 is raised, so that the projection 2a is turned counterclockwise. Resultantly, the phase angle of a driving shaft 2 and a driven shaft 3 is changed.

Title: Magnetic disk device
Inventor: HOSHI AKIO
IPC: G11B17/028
Filed: 1981-03-19
Abstract: PURPOSE: To prevent a magnetic disk and a magnetic head from being damaged, by pinch-holding the magnetic disk by making one of pinch-holding members provided on both surfaces of the magnetic disk so as to be opposed to each other, by at least 2 steps against the other pinch-holding member.  
     CONSTITUTION: When a cover member 12 is rotated in the direction as indicated with an arrow 14 centering on a supporting point 13, a rod member 16 supported so as to be freely slidable against a base table 15 moves in the direction as indicated with an arrow 3b against energizing force of a coil spring 17. An end part 16a comes into press-contact with an inclined surface 17a of a lever 17, and pushes it up in the direction as indicated with an arrow 18. A press-contact part 17b of the other end of the lever 17 pushes up a disk 5a provided on a solenoid 5 centering on a supporting point 20, and a space T between magnetic head 10, 11 becomes small. Subsequently, an actuator 6 and the magnetic head 10 are furthr made to go down in the direction as indicated with an arrow 9b by operating the solenoid 5, and a magnetic disk which is not shown in the figure is pinch-held. In this way, when the solenoid is operated, a small stroke will do, and a shock and a noise are reduced.

Filed: 1978-04-07
Abstract: PURPOSE: The purification of m-dinitrobenzene that is used to for m-phenylene- diamine or m-nitroaniline is conducted by using an aqueous solution of sodium hydroxide with a specific concentration and treating it in a specific temperature range.  
     CONSTITUTION: In the purification of m-dinitrobenzene resulting from nitration of benzene or nitrobenzene with a strong mix acid, an aqueous solution of sodium hydroxide with a concentration of less than 9%, preferably 4W7% is employed and the treatment is effected by stirring the mixture in a temperature range from 91 to 100, preferably from 93 to 97°C for about 4 hr and standing for a prescribed time at a temperature of over 85°C. Then the waste alkali is separated. m-Dinitrobenzene separated is rinsed with hot water to remove remaining alkali, thus giving purified m-dinitrobenzene.  
     EFFECT: The treatment can be effected simply within a short time, thus being good  in reaction efficiency and yield and giving economically high-quality product.  
     USE: An synthetic intermediate.

Title: Built-up transmission shaft
Inventor: SWARS HELMUT
IPC: F16H57/02
Filed: 1989-02-22
Abstract: PURPOSE: To improve the bending and torsional stiffness of an assembled drive shaft by non-rotatingly connecting individual driving elements to a hollow shaft by means of a force or friction locking connection. CONSTITUTION: Individual driving elements consisting of two toothed disk 9 and 10 are directly mounted on a hollow shaft 1, and both of them are locked by a force or friction connection through inward plastic deformation in this hollow shaft 1. With this, the driving elements 6 are manufacturable as relatively uncomplicated casting parts, and connectible in conjunction with the hollow shaft 1, so that the whole number of constituent members is reducible, and further the bending and torsional stiffness of the drive shaft is thus improvable.

Title: Expandable bandage
Inventor: KOYAMA AKIE
IPC: A61F13/02
Filed: 1990-02-21
Abstract: PURPOSE:To realize an expandable bandage which expands sufficiently and moreover, has a specified self-adhesiveness by coating a material for the bandage with silicon. CONSTITUTION:This expandable bandage is made up of a cloth 1A for a bandage coated with silicon 4 and has excellent, expandability and self adhesiveness. The silicon 4 coating the cloth 1A is dried being exposed to an atmosphere of a room temperature gradually being divided by multiple stages. Therefore, the silicon 4 dried previously on the side of a low temperature covers the cloth 1A. Especially, when the cloth 1A made of a synthetic resin is used, this can prevent a trouble of melting the cloth 1A or others as caused by a high temperature drying. In addition, such a drying by multiple stages enables drying maintaining the adheiveness without solidifying the silicon 4 thereby assuring excellent expandability and adhesiveness.

Title: Bus arbitration circuit
Inventor: SATOMI SEIICHI
IPC: G06F13/28
Filed: 1994-02-16
Abstract: PURPOSE:To arbitrate a bus of FIFO where data are temporarily stored and the bus of an MPU(microprocessor unit) through simple constitution. CONSTITUTION:Once serial data SD are inputted, SCU(serial control unit) 2 outputs a received signal RDY. A DMA controller 4 requests the MPU 1 to transfer the right to use the bus 7 and enters a DMA cycle to transfer the data from the SCU 2 to the FIFO 3 with a signal ACK. The FIFO 3 outputs a received signal FRDY and the MPU 1 reads the data out of the FIFO 3 after other processes end. Therefore, the DMA controller 4 has the right to use the bus 7 during the data transfer, so the MPU 1 can not access the SCU 2 and the bus arbitration is performed through the simple constitution.
