IPC: H01L23/31
Filed: 1987-05-21
Abstract: PURPOSE:To obtain spherical quartz glass powder which is high purity and has projecting parts of a network pattern on the surface with high yield, by dispersing the partial condensate of water-insoluble silicon alkoxide into water and calcining the pptd. silica gel. CONSTITUTION:Sol of partial partial condensate of silicon alkoxide is formed by hydrolyzing silicon alkoxide with water of 0.7-1.3mol. times for 1mol. of silicon alkoxide under the existence of acid and alcohol. Then the partial condensate of water-insoluble silicon alkoxide is formed by removing alcohol from this sol. Thereafter the ppt. of silica gel is formed under the existence of a gelling agent by dispersing the partial condensate of water-insoluble silicon alkoxide into water and the aimed quartz glass powder is obtained by calcining the pptd. silica gel. The composition obtained by mixing this quartz glass powder with resin is large in the contact area of the powder and resin and is excellent in fluidity and is free from impurities and therefore is especially suitable for seal of a semi-conductor device.

Inventor: NAKAMURA MASAKAZU
IPC: G01V9/00
Filed: 1985-06-07
Abstract: PURPOSE:To detect always an abnormal signal with constnt sensitivity by detecting individually intensities of beams of interference light branched after passing a polarization plane adjuster which adjusts the polarization state of light. CONSTITUTION:Interference light generated by a interference light generating part 3 is branched into two paths by an optical distributor 8, and intensities of individual beams of the interference light are detected by light intensity detectors 5p and 5s individually, and combinational signals of them are operated and processed by an operation processor 6 to detect abnormality. Planes of polarization are set to adequate states by light polarization plane adjusters 7a and 7b while monitoring intensities detected by detectors 5p and 5s. Thus, one interference pattern is not in a detection sensitivity degradation area when the other is present, and the abnormal signal is detected with a high sensitivity by one interference light internsity at least, and abnoramality is always detected with high sensitivity.

Abstract: PURPOSE:To measure the amount of thermal offtrack by the magnetic disk device itself by providing an A/D converter to convert a position signal to a digital value and a means to transmit the value after conversion by the A/D converter to a positioning sequence control microprocessor in a head positioning control circuit. CONSTITUTION:A position signal generating circuit 5 transmits a position signal (f) based on a head positioning information signal (e) from a head/disk assembly 3. An offtrack correcting circuit 4 inputs a read data signal (d) to be outputted from a data head selected by the head/disk assembly 3, extracts offtrack correction information in respect to a head under selection included in this read data signal (d) and outputs the information to a servo analog circuit 6 as an offtrack correction signal 6. The servo analog circuit 6 makes the value of the signal (h) close to '0' and executes positioning correction to the track center of the head. An A/D converter 7 converts the position signal (f) at that time to a digital signal and outputs it to a sequence control microprocessor 9 as an offset data signal (k).

Title: Filter
Inventor: MIYATA HAJIME
IPC: B01D29/62
Filed: 1998-05-06
Abstract: PROBLEM TO BE SOLVED: To wash easily even solid impurities of about 1 μm by peeling by a method wherein a granular filter medium wherein a filtration layer is formed on a porous support of a casing, is vibrated in back washing. SOLUTION: Sufficient filtration of bacteria of about 1 μm in a size of a fine solid particle or the like which are contained in water can be executed by using a granular filter medium 3 of about 1 μm in particle size for a casing wherein water to be filtered is exhausted from a wastewater opening 5 via a granular filter medium 3, and a support 2 from a feedwater opening 4. When water is passed toward the feedwater opening 4 from the wastewater opening 5 for back washing, the water passing through the support 2 washes the granular filter medium 5 to be exhaused from the feedwater opening 4.  When a driving circuit 7 is operated in the back washing, a vibration generating element 6 generates mechanical vibration, excites the support 2 and the granular filter medium 3 by vibration, and peels off a solid particle or the like of the stuck impurity to be exhausted together with the wastewater outside the system. Thereby, even a fine solid particle and bacteria of about 1 μm in particle size can be peeled off to be washed.

Filed: 1989-05-17
Abstract: PURPOSE:To smoothly control the shape of a steel strip by rolling the steel strip by a tour high mill consisting of back-up rolls which are longer in the length of cylindrical parts than the length of to cylindrical parts of work rolls and are provided with tapered piston type variable roll crown mechanisms. CONSTITUTION:Tapered pistons 7 are pulled out in both end directions of the cylindrical parts and the roll profiles of the backup rolls 2a, 2b are set to a projecting crown.
