Title: Method and instrument for measuring radius of curvature of curved surface
Inventor: SUZUKI SEIZO
IPC: G01B11/255
Filed: 1990-03-27
Abstract: PURPOSE:To measure the accuracy and shape of the surface by shifting a reference surface slightly on an optical axis, finding the difference of the focus position of coherent light from variation of pieces of surface information before and after the shifting, and finding the radius of curvature of the surface to be measured from the shift quantity and the difference of the focus position. CONSTITUTION:Interference fringes are formed and image is formed on an image sensor 8 by determining the distance between the reference surface 5a and the surface 6a to be measured so that the center of curvature of the plane of an incident wave front from the reference surface 5a is aligned with the center of curvature of the surface 6a to be measured. Then an objective 5 is shifted slightly by a known quantity DELTAon the optical axis without decreasing the contrast of the interference fringes. Therefore, the optical paths of the incident wave front and a reflected wave front do not match each other, the center of curvature of the incident wave front shifts by the quantity DELTA from a point A0 to a point A1, and the center of curvature of the reflected wave front shifts by a quantity (p) from the point A0 to a point A2. For the purpose, the quantity (p) is found and then the quantity DELTA is already known, so the radius (r) of curvature of the surface 6a to be measured can be found.

Abstract: PROBLEM TO BE SOLVED: To suppress lowering of the molecular weight and gelation of a maleic anhydride-modified diene-based rubber by oxidation degradation and to increase an introduction rate of maleic anhydride by reacting a diene-based rubber and maleic anhydride in the presence of a phenol-based antioxidant having an alkyl thioether structure in the molecule. SOLUTION: Phenol-based antioxidants having an alkyl thioether structure in the molecule include compounds of the formula. In the formula, R1, R2 and R3 are each a 1-20C hydrocarbon; (m) and (n) are each 1-4; and m+n<=5. In particular, phenol-based antioxidants having two sulfide linkages are preferred and 2,4-bis[(octylthio)methyl]-o-cresol is the most preferred. The reaction is conducted at a room temperature to 200 deg.C. A more preferred effect can be obtained by using the phenol-based antioxidants having an alkyl thioether structure than by using the conventional phenol-based antioxidants and phenol-based antioxidants having a phenyl thioether structure.

Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To damp the vibration of a connected building by mounting an energy absorbing mechanism held at a fixed fitting angle in the horizontal plane on the walls opposite to each other of a connected building out of two buildings of different vibration characteristics. SOLUTION: Oil dampers 5 are mounted on a building so as to be at a fitting angle of nearly 45 on the horizontal plane, and installed on a plurality of positions in the width direction and the height direction of the building. For example, earthquake force acts on a connected building 20 composed of a large- sized building 1 and a small-sized building 2, and the large-sized building 1 and the small-sized building 2 are respectively vibrated in a horizontal plane. Next, vibrations are transmitted to the oil dampers 5 through frames 4a, 4b, and pistons are reciprocated in cylinders. Interlocking with this oil is communicated in bypass passages, and vibration energy is absorbed by viscous resistance generated by alternate movement of oil in the cylinders. Hereby, vibrations of both ones 1, 2 of the connected building 20 can be damped.

Title: Diode
Inventor: HIKITA JIYUNICHI
IPC: H03G11/00
Filed: 1982-05-07
Abstract: PURPOSE:To set freely the forward drop voltage, by providing an amplifier which generates an output when the input voltage exceeds the offset voltage and a transistor which feeds the output back to the offset input side of said amplifier. CONSTITUTION:The input voltage Vin is applied between terminals 10A and 10C. When this voltage Vin exceeds the offset voltage Voff of an amplifier 12, the amplifier 12 starts its operation. Then the Vin is amplified and applied to the base of a transistor TR14, and therefore the TR14 is actuated. The current flowing through the TR14 corresponds to the applied voltage Vin and flows to a resistance 18 from a terminal 10B. The voltage generated at the resistance 18 is fed back to and superposed on the voltage Voff. As a result, a diode can be set at an optional level from a low level of voltage equal to several mV through a level higher than the forward drop voltage of an ordinary diode.

Abstract: PURPOSE:To enhance the oscillating efficiency by arranging vanes having a mating surface closely to a ring-shaped electron beam, and enlarging the interacting range of electron beam with microwaves. CONSTITUTION:A ring-shaped electron beam is accelerated by a ring-shaped anode 10 in the axial direction to intrude into a resonator 3 while rotated in the radial direction by the radially oriented magnetic field in an aperture provided in a partition plate 9 to oscillate microwaves with the frequency depending upon the number of vanes from an antenna 11 while rotating at cyclotron frequency depending upon the axially oriented magnetic field in the resonator.
