Inventor: UIRIAMU BAUAA JIYUNIA
IPC: C07C69/593
Filed: 1995-06-08
Abstract: PURPOSE: To simply and profitably remove carbonyl-containing impurities by perfectly mixing an α,β-unsaturated carboxylic acid ester with an aqueous solution of a bisulfite salt or dithionite salt and subsequently separating the phase of the ester from the mixture.

Title: Magnetic head
Inventor: YOKOYAMA OSAMU
IPC: G11B5/31
Filed: 1983-09-07
Abstract: PURPOSE:To obtain a signal with a high SN ratio extending up to high recording density by extending the length of the rear end part of a magnetic pole in the breadthwise direction of a track to direct the axis of easy magnetization to this breadthwise direction. CONSTITUTION:Soft magnetic thin films 3-1 and 3-2 are connected by a rear end part 305, and a gap 3-3 is formed in a head front end part by a nonmagnetic material. A coil 3-4 is wound between thin films 3-1 and 3-2 through an insulating film. The length of the rear end part of the magnetic pole in the breadthwise direction of the track is made longer than a track width W in this manner to direct the axis of easy magnetization to the direction of an arrow 3-6. If an external magnetic field is impressed in the direction of the arrow 3-6 when the thin films 3-1 and 3-2 are stuck, magnetic anisotropy is strengthened. In comparison with a head where the axis of easy magnetization is not directed to the direction of the arrow 3-6, the high S/N ratio is attained up to the high recording density.

Title: Deflection yoke of cathode-ray tube
Inventor: OOMURA NORIO
IPC: H01J29/76
Filed: 1990-06-21
Abstract: PURPOSE:To enhance the deflecting efficiency by furnishing an aux. coil in the back part on its electron gun side, and allowing this aux. coil to generate a magnetic field to produce a deflection in the opposite direction to predeflection made by leaked magnetic field. CONSTITUTION:An aux. coil 18 is installed behind a deflection yoke 11 on its electron gun 15 side, and a vertical deflection electric wave is flowed to this aux. coil 18. The direction of mag. field generated by the aux. coil 18 is opposite the vertical main deflecting mag. field 21 generated by a vertical deflection coil. An electron beam is predeflected in the same direction as vertical deflection by the leak mag. field of the deflection yoke 11, in particular this vertical deflection coil 13. If a magnetic field 20 is generated by the aux. coil 18, however, the electron beam is deflected in the opposite direction by this magnetic field, and the beam proceeds. Therefore, the deflecting amount of the beam becomes small when it intrudes into the main mag. field of the deflection yoke 11, which enables increasing the neck shadow margin.

Title: Rotary multiplate damper with automatic temperature sensing-damping force adjusting mechanism using viscous fluid
Inventor: SUGASAHARA MORIHARU
IPC: F16F9/12
Filed: 1987-07-01
Abstract: PURPOSE:To enable the damper to maintain a constant damping force regardless of ambient temperature by forming fixed plates unmovable in the direction of rotation of the movable shaft by engaging them with a casing, and forming both fixed and movable plates movable in the direction of their thickness, and forming the front or a part of one or both plates out of each fixed and movable plate by a temperature sensing deforming member. CONSTITUTION:A fixed plate 7 is formed integrally with a temperature sensing deforming member 7c held by silicon rubber, etc., by means of an adhesive, etc. between the two upper and lower discs. Thus, when the atmospheric temperature rises in summer, the temperature sensing deforming member 7c becomes thicker due to the silicon rubber, the thickness of the fixed plate 7 is also increased, and the clearances between movable plates 6, 6... and fixed plates 7, 7... are reduced as a whole. As a result, even if the viscosity of a viscous fluid A is lowered as the atmospheric temperature rises, the damper can be constantly regulated to a desired constant value throughout the year by increasing the viscous shear resistance through the reduction in spacing of the clearances between each plate, without lowering the damping force at the time of temperature rise.

IPC: A23L2/00
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To safely produce a weakly acidic chlorine based sterilizing water by adjusting pH of salt water using carbon dioxide before the salt water is diaphragmlessly electrolyzed and then executing diaphragmless electrolyzing. SOLUTION: The pH of the dil. salt water is adjusted to 4-5 by housing, for example, a 0.1wt.% dil. salt water in an adjusting tank 11 and supplying gaseous carbon dioxide in a carbon dioxide cylinder 13b to the adjusting tank 11 through a ejecting pipe 13a. The dil. salt water adjusted with pH is supplied in a cell main body 12a of an electrolytic cell 12 by a feed pump 15a, diaphragmlessly electrolyzed during flowing between both positive and negative electrodes 12a and 12c, where a current is made to flow, and an electrolyzed water produced in the cell main body 12a flows out from a flowing-out passage 14b to a water storage tank.  As a result, the resultant electrolyzed water does not causes the erosion or the corrosion of a device due to a strong acidic water and the deposition of insoluble scale or the like due to alkalinity because a strong acidic water or alkaline water is never produced.

IPC: F02D45/00
Filed: 1990-06-26
Abstract: PURPOSE:To enhance the degree of accuracy for several kinds of controls in accordance with an opening degree which is properly detected, by performing compensation upon full closing of throttle valves so that the opening degree is determined by comparison in accordance with an absolute throttle relative opening degree and a true opening degree. CONSTITUTION:A first compensating means carrier out compensation for eliminating a deviation in output voltage upon full close of two throttle sensors so as to compensate an absolute opening degree detected by an opening degree detecting means, and thereafter, a second compensating means compensates the relationship between outputs from the two throttle sensors, corresponding to a difference between the opening degrees of two throttle valves. Accordingly, output voltages corresponding to the absolute opening degree and the relative opening degree which are identical with each other are compensated so as to have one and the same value. An opening degree selecting means compares the opening degrees of the two throttle valves with each other for the thus compensated absolute and relative opening degrees, and smaller one of them is selected as a detected throttle opening degree. With this arrangement, of two opening degrees of the throttle valves, the smaller one is properly selected, thereby it is possible to use its as a throttle opening degree.
