Title: Yoke clip
Inventor: KOIKE TETSUYA
IPC: F16D1/02
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a yoke clip with greatly improved workability. SOLUTION: This clip is provided with a main body 111 installed to a yoke 101 and a spring part 112 protruded between tabs 101b through a bolt insertion hole 101a. When a shaft 102 is installed to a fitting part in the yoke 101 via a clearance between the tabs 101b, the spring part 112 is pulled inside the bolt insertion hole 101a so as to allow passage of the shaft 102, however, after the shaft 102 is installed to the fitting part, the spring part 112 prevents separation of the shaft 102 from the yoke 101. As a result, a dimension between the tubs 101b in the yoke 101 is equalized to the width of the shaft 102 substantially, so that a gap generated between the yoke 101 and the shaft 102 can be reduced. The spring part 112 is engaged with a thread part in a bolt so as to prevent the bolt from slipping off.
Patent JP-S6088334-A (JP)
Title: Pressure detector
Inventor: KATOU YOUJI
IPC: G01L1/20
Filed: 1983-10-19
Abstract: PURPOSE:To obtain a sensitive and stabilized detector, by placing a pressure- sensitive rubber band between first and second band-shaped electrodes and covering with a deformable covering member. CONSTITUTION:A case 4 composed of end (a), side (b) and edge (c) portions is of a recessed cross section, thicknesses of edge (c) and side (b) portions are mode thinner than the thickness of the end portion (a). Now, pressure applied to the case 4 is transmitted to a pressure sensitive rubber piece 1 through an electrode 3 by buckling of the case 4 itself and the piece 1 receives pressure as squeezed between electrodes 2, 3. The band-shape rubber piece 1 is, when pressure is zero, provided with almost infinite resistance value, however, even if its area is limited, when pressure exceeds the specified value, then the resistance value changes to an extremely small one, for example, a few OMEGA/cm<2>. An electic current applied between the electrodes 2, 3 allows a current to flow between the electrodes 2, 3 which is detected with an electric circuit for its magnitude. Thus, it is possible to tell whether pressure was applied to the pressure-sensitive rubber piece 1.

Title: Magnetic disk device
Inventor: ENDO KENICHI
IPC: G11B21/16
Filed: 1985-09-05
Abstract: PURPOSE:To prevent slippage of a joined part due to vibration, shock and heat by fixing a magnetic head mounting member to a carriage with a counter- sunk screw made of a material having the same coefficient of thermal expansion with the head mounting member. CONSTITUTION:A magnetic head 12 that performs recording and reproducing is fixed on the carriage of a magnetic disk 11 through a head mounting member 14. To fix the magnetic head, a counter-sunk screw is used as a fitting screw 18, and spot facing is made on the member 14. At the time of fixing, the force that thrusts the spot faced part in circumferential direction is generated in the member 14 and the screw 18 by wedge effect together with axial force, and the member 14 becomes hard to slip. Further, by making the coefficient of thermal expansion of the screw 18 equal to that of the member 14, lowering of axial force due to change of temperature can also be prevented. In this way, the slippage of jointed part of the head mounting member and carriage due to vibration, shock and heat can be prevented.

Title: Method and apparatus for transferring substrate
Inventor: NAKAZAWA YOSHIYUKI
IPC: H01L21/677
Filed: 1994-08-22
Abstract: PURPOSE: To obtain a convenient space saving apparatus for transferring a substrate requiring no aligning apparatus for exclusive use. CONSTITUTION: A hand 102 can support a wafer 11 having an orientation flat 11a. An arm 92 moves the hand 102 to gain access to a wafer 11 set in a cassette 13. The hand 102 has a head 132 bonded with edge sensors 132a-132c at an interval wider than the execution width of the orientation flat 11a in the direction normal to the advancing direction of the hand 10 gaining access to the wafer 11 and parallel with the surface of the wafer 11. A controller determines three edge positions of the wafer 11 based on the outputs from the edge sensors 132a-132c and the positional information of the hand 102. Assuming that at least two out of three edge positions thus determined are present on one circle, the central position 111c of the wafer 11 is determined as the center of the circle and then the hand 102 is shifted based on the central position 111c.

Title: Quality assessment method for galvanized steel sheet
Inventor: NAKAMORI TOSHIO
IPC: G01N23/207
Filed: 1986-08-22
Abstract: PURPOSE:To enable prompt assessment of the quality of a zinc hot dip coated or zinc alloy hot dip coated surface by projecting a monochromatic X-ray to said surface and comparing the X-ray diffraction intensities of the arbitrary index plane of the Zn crystal in the plated surface and the index plane parallel therewith. CONSTITUTION:The monochromatic X-ray is projected to the zinc hot dip coated or zinc alloy hot dip coated surface and the X-ray diffraction intensities of the arbitrary index plane of the Zn crystal in the plated surface and the index plane parallel therewith are measured. The two intensities are then compared. The resistance of a galvanized steel sheet (more particularly zero spangle material) to exfoliation with lapse of time is evaluated by using preferably an online installed X-ray diffraction instrument (for example, deffractometer diffraction analyzer). The information obtd. in such a manner is not only helpful for the direct evaluation of the quality of said steel sheet but also feedable back to a production side by using an adequate control means.

IPC: B23D1/26
Filed: 1992-07-01
Abstract: PURPOSE:To manufacture a square tube excellent in flatness of a plain part, small in corner dimension and excellent in shape characteristic by butting two steel strips having a U-section each so that they face each other, then, welding the butted edges. CONSTITUTION:Linear grooves G1-G4 extending in the longitudinal direction of steel strips S, S1, S2 are formed by rolling through a grooving roll, grinding, etc. The steel strips S, S1, S2 bent with the linear grooves G1-G4 as a polygonal to right angles in the width direction and edge parts in the width direction of the steel strips S, S1, S2 are butt-welded. One S of the steel strips is bent in the shape of a rectangular section and both edge parts in the width direction are butt-welded, or the edge parts of the U-section steel strips bent in the same way are butt-welded to manufacture a square tube. Therefor, since the steel strips S, S1, S2 are bent along the linear grooves G1-G4 in the width direction, the corner parts take a linear state along the horizontal direction of the steel strip. Since the flatness of the plain parts P1-P4 is improved, the groove edge shapes J, J1, J2 formed by butting both edge parts in the width direction of the steel strips S, S1, S2 are stabilized.
