IPC: H01L21/68
Filed: 1985-11-01
Abstract: PURPOSE:To carry out grinding with excellent parallelism by forming grooves in a zone covered by a workpiece, of a surface on which said workpiece is placed, and forming plural holes which connect said grooves to a vacuum source. CONSTITUTION:A chuck body 1 is formed with a silicone crystal which is the same material as a silicone wafer. A workpiece 4 is also made of the same material as that of the chuck body 1, having the same grinding resistance and with a form error being theoretically zero, reducing the form error when the workpiece 4 is placed on a plane surface. Grooves 9 provided on the surface of the chuck body 1 are connected to a vacuum source via a hole 10, to adsorb and fix the workpiece 4. Accordingly, the use of such a vacuum chuck enables the grinding of a silicone wafer with excellent parallelism.

IPC: D05B47/04
Filed: 1988-09-30
Abstract: PURPOSE:To automatically properly adjust the tension of a thread according to changes in variable sewing requirements such as a change in cloth thickness or the like and the variation of environment in sewing such as temperature, humidity or the like by controlling a thread tension controlling means to automatically adjust the thread tension through a pinching means by a control amount of a reference value calculated on the basis of respective data of a data table corresponding to variable information detected by an information detecting means. CONSTITUTION:A difference (Pn)-(Pn-1)=(DELTAPn) between total displacement Pn and total displacement (Pn-1) calculated in the previous interruption is calculated. The positive or negative symbol of (DELTAPn) is judged as a result of the calculation. In the symbol of zero, i.e., (DELTAPn)=(Pn-1) the interruption program is completed. When (DELTAPn)<0, a pulse motor 16 rotates in the direction of CCW corresponding to the deviation. To the contrary, in (DELTAPn)>0, the pulse motor 16 is rotated clockwise CW by (DELTAPn) to intensify the tension of a thread. AS a result, a holding shaft 29 is displaced left by delta to intensify spring pressure T due to a conical spring 28 and the tension of the thread. Thus, a change in the cloth thickness T of a sewn cloth 6 under working is always checked to control the thread tension into an optimum condition.

IPC: C08L61/06
Filed: 1983-12-27
Abstract: PURPOSE:A phenolic resin composition having excellent heat resistance, moisture resistance, and fast-hardening properties, containing a phenolic resin with a biphenol structure in its skeleton. CONSTITUTION:A resin composition containing a phenolic resin having, in its skeleton, a biphenol structure such as a polymer of biphenols and aldehydes, a copolymer of biphenols, phenols, and aldehydes, and a copolymer of biphenols, alkylbenzenes, and aldehydes.

Title: Magnetic recording medium
Inventor: KITAORI NORIYUKI
IPC: G11B5/84
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To obtain good traveling property by forming a metal thin film magnetic layer on a base body, controlling the total thickness to a specified value or smaller, and forming the magnetic layer in such a manner that values of loop stiffness of the medium measured when the magnetic layer is arranged inside and outside differs from each other. SOLUTION: This magnetic recording medium is produced by forming a metallic thin film type magnetic layer on a supporting body and has <=6μm total thickness. The magnetic layer is formed by using a ferromagnetic metal material such as Co, Ni, Fe by oblique vapor deposition on the supporting body to obtain 900 to 3000Å film thickness. The loop stiffness of the medium measured when the magnetic layer is arranged outside is made smaller than the loop stiffness measured when the magnetic layer is arranged inside. Further, a back coating layer of 0.05 to 1.0μm thickness is formed on the concave curved face of the supporting body. Further, a diamond-like carbon protective layer and a lubricant layer are formed thereon. Thus, even when a thin magnetic layer is formed on a thin supporting body, the obtd. medium shows good traveling property.

Abstract: PURPOSE:To recover heat, condense a steam stream and return the condensed steam, by taking the steam stream as a side stream out of a plate near a raw material feed plate of an acetonitrile concentrating and recovering column in separating and purifying butadiene and isoprene using a mixed solvent of acetonitrile and water as an extracting solvent. CONSTITUTION:Butadiene and isoprene are separated and purified from a 4-5C hydrocarbon mixture in high purity using a mixed solvent of acetonitrile-water as an extracting solvent by an extractive distillation method. In the process, a stream stream is taken out of a plate near a raw material feed plate of an acetonitrile concentrating and recovering column as a side stream to recover heat. The stream stream is then condensed and returned to the plate from which the side stream is taken out. Thereby the heat recovery of high quality is carried out without impairing the water balance of the extracting solvent system. The heat recovery ratio can be further improved by dividing the acetonitrile concentrating column into the lower part 2 and the upper part 3 respectively connecting the steam stream and liquid stream and operating the upper part under a low pressure and the lower part under a high pressure.
