Title: Method and device for reproducing magneto-optical information
Inventor: OKAZAKI YUKINORI
IPC: G11B11/105
Filed: 1990-09-20
Abstract: PURPOSE:To realize the magneto-optical information reproduction of few noises, large signal reproducing margin and high reliability by controlling a differential input signal at the time of differential detection with the difference of the quantities of light of two polarized components intersecting almost orthogonally with the light reflected or transmitted from/ through a magneto-optical recording medium. CONSTITUTION:The light emitted from a laser beam source 1 is reflected by a magneto-optical disk 2, and the polarized state or reflected light 6 is changed by an information signal recorded on a magneto-optical recording film 3. This reflected light 6 is separated into two polarized components intersecting almost orthogonally with each other by using a polarizing beam splitter 7, and they are received by different photodetectors 8, 9. The output difference of signal amplifiers 10 to amplify the outputs of these photodetectors 8, 9 is detected by a DC differential amplifier 11, and one of the signal amplifiers 10 operates so as to increase an amplification factor higher than a reference amplification factor, and the other side operates so as to reduce the amplification factor lower than the reference amplification factor. Thus, the output becomes 0, and the noise of an AC differential amplifier 12 to generate a regenerative signal is canceled by the differential amplifier 12, and regenerative output 13 whose signal amplitude is uniform can be obtained.

Title: Polishing method and polishing member for magnetic recording medium
Inventor: NISHIYAMA TOSAKU
IPC: G11B5/84
Filed: 1988-10-06
Abstract: PURPOSE:To assure sufficient contact and to improve polishability and polishing speed by escaping air through the many holes provided on the polishing member and a porous guide post at the time of allowing a recording medium and the polishing member to travel in contact with each other and polishing the recording medium. CONSTITUTION:A lapping tape 1 is wound around the guide post 2 consisting of a porous sintered body having holes 9 on the peripheral surface and travels in a direction B. A video tape 6 is wound around the guide post at a different winding angle and travels in the direction A in such a manner that the magnetic layer comes into contact with the tape 1. The tape 1 is constituted by forming an abrasive layer on a base body and is formed with many circular through holes in the longitudinal direction. Since the air can be escaped through the holes of the tape 1 and the porous post 2 in the case of executing polishing by bringing the tapes 1, 6 to travel in contact with each other, the generation of an air layer in the tape contact surface is prevented. The sufficient contact is obtd. in this way and the good polishability is obtd. The increase of the polishing speed is thus possible.

Title: Composite machine
Inventor: WATANUKI MASAYOSHI
IPC: H04N1/04
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To obtain an optimum image, even for any function executed by a composite machine by correcting an operating condition set by a user, based on corruption data read out of a storage means. SOLUTION: When a function selected by the user is the copy mode, correction data to correct a magnification stored corresponding to a copy function are read out of a ROM 207. A corrected magnification as an operating condition to actually activate a scanner is obtained from the correction data decided by taking thermal contraction, when recording paper passes through a fixing device into account and the correction magnification as the magnification in the main scanning direction an the subscanning direction of the scanner is sent to a scanner control section 201. When the function selected by the user is the scanner mode, correction data corresponding to the scanner mode are read out of the ROM 207. Thus, the magnification set by the user is corrected by the correction data stored in the ROM 207, corresponding to each function.

Title: Cdma base station device
Inventor: TANAKA YASUHIDE
IPC: H04B1/707
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To use even a user registered in a different sector for an object of interference elimination processing. SOLUTION: The CDMA base station device 1 is configured to include interference cancellers 10A-10H. A main user and a sub user can be registered to each interference canceller 10 and conducts interference elimination processing including the main user and the sub user. Thus, when a user is registered to the interference canceller 10 as a main user and registered to other interference canceller 10 as a sub user, the interference of the sub user in the other interference canceller 10 onto the main user can be eliminated. In this case, a provisional decision result (information symbol) required for the interference elimination processing with respect to the sub user can be acquired from the interference canceller 10 to which the same user is registered as the main user.

Title: Machining area division process device for turn-machining
Inventor: NAKAMURA SOHEI
IPC: B23Q15/00
Filed: 1986-10-23
Abstract: PURPOSE:To make it possible to obtain optimum machining information rapidly by employing a machining area drawing setting section, a division element setting section, a process division element setting section, a process division area takeout process section, and a machining area drawing deletion process section. CONSTITUTION:A machining area drawing setting section 3 develops a machining area drawing data based on a turn-maching drawing data and a material drawing data. A division element setting section 7 specifies the machining area to be either front side or back side machining based on a position setting data and, in the case of the front side machining, sets a condition of outer or inner circumference. A process division area setting section 8 develops by its setting a closed area in the machining area. A process division area takeout process section 9 takes out the closed area as a process division area from the machining area drawing data. A machining area drawing deletion process section 10 deletes the process division area from the machining area drawing data and develops the remaining area into a remaining machining area drawing data. The remaining machining area data undergoes the above-mentioned procedure again by means of the division element setting section 7.

Lead wires are fixed and bonded to silver electrodes by using an Ag-Pb-Sb eutectic solder. This assembly is heated by using a heater; it is immersed in a powdery resin by leaving the lead wires partially; and a varistor element covered with a resin layer is obtained. An impulse discharge current is applied; and the change rate of a varistor voltage V1mA before it is applied and after it has been applied is found. It is possible to obtain a voltage-dependent nonlinear resistor whose change rate of the varistor voltage V1mA is small and whose impulse discharge- resistant amount is large.

Abstract: PURPOSE:To produce a molten iron of low Si and low S contents by preparing iron ore powder and composite compd. powder composed of CaO and MgO into a slurry with water and blowing the slurry through tuyeres into a blast furnace during the operation thereof. CONSTITUTION:The iron ore powder, limestone powder and powder of composite compd. raw materials composed of CaO and MgO such as serpentine and dolomite are respectively put into service hoppers 1, 2, 3, and are supplied by rotary feeders 4, 5, 6 into a mixing tank 8.

The slurry is blown by a slurry pump 9 via a distributor 10 into the blast furnace through the plural tuyeres 12 thereof so as to be blown from a nozzle 11 into the furnace. The Si of the molten iron in the blast furnace is oxidized by Fe2O3 in the iron ore to form slag, by which the content of Si is decreased. The basicity of the slag is increased by a basic slag forming agent such as CaO or MgO, by which the content of S in the molten slag is decreased in the stable descending state. H2 is generated by the decomposition of the water in the slurry, by which slip generation frequency is decreased.
