Title: Recording and reproducing device of magnetic disk
Inventor: TANAKA YOSHIHIRO
IPC: G11B5/265
Filed: 1983-02-08
Abstract: PURPOSE:To reduce the track pitch error and to eliminate the use of parts having high precision for the chucking mechanism of a disk or the feed mechanism of a head, by distributing a record/reproduction head and an erasing head at both sides of the disk center line. CONSTITUTION:The distance between a center line A-A' and a record/reproduction head gap 8 is set at 0.35mm., and the gap distance GL between a record/reproduction head 5 and erasing heads 6 and 7 is set at 0.7mm.. In such a case, the heads 6 and 7 are symmetrical to each other centering on the line A-A' and therefore the offset of the heads 6 and 7 is not needed to the head 5. Thus the track pitch error can be reduced under such a positional relation, and therefore the track pitch error ratio is reduced to an allowable gap (tracking error) between the track and the head. As a result, the satisfactory record/reproduction performance is obtained without using the parts of high precision for the chucking mechanism of a disk or the feed mechanism of the head.

Title: Motor-controlling device and disk storage using the same
Inventor: TAKARA KAZUHIRO
IPC: H02P29/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of a rotation load in low-temperature operation environment, and to consequently achieve stable rotary operation at a rated value in a device using a fluid bearing motor. SOLUTION: When a CPU 60 activates an SPM(spindle motor) 11, the CPU 60 judges whether a rated speed is reached or not by the speed detection circuit of a motor driver 61. When the rated speed is not reached, the CPU 60 judges that the operation environment of the SPM 11 is at a low temperature, and an overcurrent is allowed to flow to the coil of a motor for increasing ambient temperature, thus relatively reducing the coefficient of viscosity of fluid in a fluid bearing, and hence consequently suppressing the rotary load of the motor.

Title: Industrial vacuum furnace
Inventor: YOAHIMU BININGU
IPC: C21D1/773
Filed: 1985-02-06
Abstract: An industrial furnace for heat-treating metallic workpieces has separate heating and cooling chambers. The latter uses a circulating cooling gas, the flow of which against or past the workpieces produces cooling or gas-quenching. The furnace may have another chamber for oil-quenching lying below the gas-cooling chamber. In order to enable the gas cooling to operate quickly and efficiently, a cooling box fed with air by ventilator fans is provided in the shape of a tunnel, with internal surfaces above and at both sides of the effective cooling space constituted by interchangeable nozzle plates (or blank plates if no nozzle openings are desired at the top or at the sides). The workpieces to be cooled rest on a platform which may be raised or lowered to adjust the distance from the top nozzle plate or lowered into an oil bath. The nozzle plates provide a choice of nozzle patterns for different articles or groups of articles to be cooled after heat treatment. The nozzle plates may have setbacks or protrusions in order to vary the spacing of the nozzle openings from the median plane of the cooling tunnel.

Title: Recognizing method for dotted character
Inventor: NOSAKA MASASHI
IPC: G06K9/62
Filed: 1987-02-02
Abstract: PURPOSE:To recognize briefly and correctly a character by judging each splitted block as '1' or '0', and recognizing the character by pattern matching from the data in that block. CONSTITUTION:A CPU 8 is picked up by a camera 4 in a memory and read a partial image falling to a partial area suitable for recognizing a preset object from the image data from A/D converter 5 to segment the character by obtaining histograms to X- and Y-directions at the time of initializing. The area in the each of the blocks prepared by such splitting is calculated and if the calculated value is larger than the threshold value predetermined at the initialization, the area is stored as '1' and if it is smaller than the threshold value, the area is stored as '0' in the memory. The ideal data in each block for each letter prestored in the memory 6 are compared with the block data stored in the memory 6 to assume the character having the minimum difference and identify. When the difference in the comparison is larger than the threshold value preset at the initialization, it is judged to be abnormal.

IPC: H01L21/316
Filed: 1986-01-31
Abstract: PURPOSE:To form an insulating film of inorganic silica film with excellent bonding property to a surface layer while restraining a crack due to the difference in thermal expansion coefficient between a substrate and an element to be processed from occurring by a method wherein an organic silica film is processed in oxygen plasma. CONSTITUTION:An organic silica film 26 is plasma-irradiated 28 using oxygen gas at the vacuum degree of 100mTorr, output of 100W in a plasma etching device. Then, oxygen ion with high kinetic energy hits the organic silica film 26 to evaporate the solvent in organic silica film 26 further making the solvent degenerate into an insulating film 27 of inorganic silica film decomposing the organic constituent. Through these procedures, an insulating interlayer with excellent bonding property to a surface layer can be formed while forming an insulating film subject to neither cracks nor flow of pattern since this film is not affected by the differnece in thermal expansion coefficient between a substrate 20 and an element to be processed 22 due to no heat treatment applied.
