Title: Composite zinc film excellent in corrosion resistance after heating
Inventor: MORI KAZUHIKO
IPC: C25D15/02
Filed: 1991-01-31
Abstract: PURPOSE:To obtain the composite zinc film by incorporating a specified amt. of a magnesium compd. soluble in an aq. hydrochloric acid soln. of specified concn. into a zinc film or the film of a zinc alloy consisting essentially of zinc. CONSTITUTION:This composite zinc film is obtained by incorporating a magnesium compd. soluble in a 0.01 N hydrochloric acid soln. by 0.01-50%, expressed in terms of Mg, into a zinc film or the film of a zinc alloy consisting essentially of zinc. The Mg ion in the film effectively inhibits the corrosion of zinc. The magnesium hydroxide, magnesium chloride, magnesium sulfate, etc., contg. the magnesium soluble in acid are exemplified as the magnesium compd. Any metal soluble in acid and with the contained Mg capable of being ionized can be used instead of the inorg, compd. When the Mg content of the composite film is beyond the above-mentioned limits, corrosion resistance is insufficient, and the composite zinc film is formed by the impregnation method or the dispersion plating method.

Title: Oil pressure unit
Inventor: KITAGAWA NAOHARU
IPC: F15B1/00
Filed: 1994-01-31
Abstract: PURPOSE:To miniaturize an oil pressure unit, and facilitate its operation by suppressing the whole height thereof without reducing its capacity for reserving operating oil in an oil tank. CONSTITUTION:A recessed part 4 which is isolated from the inside of an oil tank 1 is formed by sinking it from upper plates 3A, 3B of the oil tank 1 in which operating oil is reserved, a vertical electrically driven motor 6 which is connected integratedly to the hydraulic pump 7 which is oriented upward is mounted in the recessed part 4, the electrically driven motor 6 mounted in the recessed part 4 is provided by opening the side of the recessed part 4 outward so as to take out the electrically driven motor 6 horizontally. In a capacity for reserving operating oil which is reduced by miniaturizing the width size and the lateral size of the oil tank 1, a reducing amount is supplemented by increasing the height of a position other than the recessed part 4 of the oil tank 1, so that increase of the height which is caused by supplementing the reducing amount is not under the influence of the recessed part 4. Even if the height of a position other than the recessed part 4 is increased, both height levels of the electrically driven motor 6 mounted in the recessed part 4 and an oil pressure pump 7 which is connected integratedly to the electrically driven motor 6 are not changed, and the whole height of the hydraulic unit can be suppressed.

Title: Peripheral storage controller
Inventor: MAEDA YUUZOU
IPC: G06F12/16
Filed: 1980-03-10
Abstract: PURPOSE:To increase extremely the reliability of write contents for the periphery devices, by storing the contents of the main storage device in each buffer memory independently and then reading these contents to write them into the duplicated peripheral devices. CONSTITUTION:The contents of the main storage device 2 is transferred to the magnetic disk controller 10 via the common bus 3 and by an indication of CPU1. This storage information receives an error detection/correction and others through a parity check and the like at the interface part 11. Then the information having the same contents are stored temporarily in the buffer memories 13A and 13B independently and through the control parts 12A and 12B. After this, the parts 12A and 12B reads the contents of the corresponding memories 13A and 13B respectively and then write them into the magnetic disk devices 4A and 4B through the interface parts 14A and 14B. Accordingly the probability is small for an error of the write contents of both device 4A and 4B even if the storage information is accumulated or read out erroneously. As a result, the reliability can be increased extremely for the write contents.

Title: Angular acceleration sensor
Inventor: YAGI TAKAYUKI
IPC: G01P15/18
Filed: 1991-01-29
Abstract: PURPOSE:To achieve a higher measuring accuracy by making a torque work in proportional to an angular acceleration about an axis by an inertial moment of a weight to detect the angular acceleration from a change in electrostatic capacitance between the weight and an electrode generated when the weight turns against an elastic force of an elastic member. CONSTITUTION:A flat weight 11 is supported with a base 13 from the front and rear thereof through an elastic support beam 12. These parts are formed integrally from a silicon base by anisotropic etching. Glass plates 14 and 15 are joined on the base 13 from top to bottom. When a clock-wise or counter- clockwise angular velocity works on an electrostatic capacitance sensor between the weights 11 of fixed electrodes 16-19 deposited on the glass plates 14 and 15, the weights 11 inclines to change an electrostatic capacitance. The change is detected with an AC bridge circuit to be converted into an angular velocity from a proportional relationship with an elastic force of the support beam 12. This enables direct and accurate detection of the angular velocity with a smaller size and a simple construction.
