Title: Optical fiber coil and optical rotation detecting device including it
Inventor: TAKEI YUKO
IPC: G02F1/01
Filed: 1991-07-05
Abstract: PURPOSE:To provide a method for constructing and mounting an optical fiber coil which reduces the zero point drift of rotation output during temperature changes, relating to an optical rotation detecting device which detects rotation of a subject to be inspected using light. CONSTITUTION:In an optical rotation detecting device a bobbin 12 (22) around which optical fiber 11 (21) is wound is located within a plane bisecting the bobbin with respect to the direction of the center axis of the bobbin and being perpendicular to the center axis and an optical fiber coil mounted on a frame is provided at that portion of the bobbin which projects from the outer or inner peripheral face thereof. The difference in the state of polarization between clockwise and counterclockwise rays of light which is caused when light is allowed to pass through the optical fiber coil is reduced and the interference output of the clockwise and counterclockwise rays of light, i.e., the zero point drift of the rotation output of an optical fiber gyro is reduced.

Title: Hydraulic actuator for piston pump
Inventor: NIWA MAKOTO
IPC: F04B9/117
Filed: 1980-11-25
Abstract: PURPOSE: To prevent surge pressure from being produced at the time of shifting a pump driving selector valve in a concrete pump or the like, by employing such an arrangement that a high-pressure oil source for a hydraulic pump is communicated to an oil tank via a restriction port when the selector valve is located at its neutral position.  
     CONSTITUTION: When a pump driving selector valve 18 is located at its neutral position, a port C and a port D are communicated to each other via a restriction port 59. Each time a drive piston 4 or 4' comes into contact with valve rods 9, 9' of control valves 6, 6', the position of the selector valve 18 is shifted and the valve 18 necessarily passes through the neutral position at the time of shifting. However, since the ports C and D are communicated to each other via the restriction port 59 even when the valve 18 is located at its neutral position and high-pressure work oil discharged from a hydraulic pump P is recirculated continuously to an oil tank T, there is no fear of rapid closing of the oil circuit, so that the surge pressure can be kept at a low level. Further, since ports A, B are closed and hydraulic cylinders 2, 2' are locked when the selector valve 18 is shifted to the neutral position, it is enabled to prevent reverse rotation of the piston pump positively during the while when its operation is stopped temporarily.

Title: Method for rolling seamless steel tube
Inventor: MORIBE KENJI
IPC: B21B37/18
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To obtain a tube with small thickness deviation in both circumference direction and axial direction by executing rolling while applying regulation and setting thereto based on the rolling load varying amount estimated by using the mutual interference coefficient affecting the rolling load between two pairs of caliber rolls set orthogonally to each other. SOLUTION: A rolled stock 2 having a core metal bar 1 inserted is rolled with two pairs of caliber rolls 3, and the variation of in a circumference direction is reduced through the use of four-roll stand. At the time of changing the roll reduction position of each of two pairs of caliber rolls set orthogonally to each other in the four roll stand, a variation amount of the rolling load applied to each caliber roll is predicted by using the mutual interference coefficient affecting the rolling load between two pairs of caliber rolls set orthogonally to each other. Based on these predicted result, the roll reduction position of each roll of two pairs of caliber rolls is decided.

Title: Method for inspecting soldering
Inventor: IWATA YUTAKA
IPC: H05K3/34
Filed: 1988-07-04
Abstract: PURPOSE:To automatically inspect soldering only by a general image input processor by using the rate of an image area having low brightness in the image of a soldering face. CONSTITUTION:An image obtained from a camera 4 is converted into image information having a density value by a processor 5 and the image information is stored. Masking excluding the picture elements of a chip 7 is executed fased on information indicating a previously inputted land 8 and the position, area and shape of a chip 7. The processor 5 finds out the area of picture elements having a low density value due to soldering 6 and the area of picture elements having a high density value surrounded by the low density picture element group. When the picture element area with the high density value exceeds a reference range, the soldering 6 is sufficiently bulged and the soldering succeeds. When the area does not exceed an error value, the value is compared with the minimum value of the validity deciding range to decide the validity. When contrast is large, binarizing processing can be also adopted, and in the case of color image processing, validity can be decided by a brightness value excluding color components.

Title: Amplifier circuit
Inventor: KAYAMA SATOSHI
IPC: G11C11/409
Filed: 1993-06-12
Abstract: PURPOSE:To obtain an amplifier circuit with a high gain by changing a drain current of a drive FET exponentially with respect to an input signal and changing linearly a drain-source voltage of a load FET with respect to a logarithmic change in the drain current. CONSTITUTION:An input signal Vin biased by a bias voltage Vgb of a negative potential is applied to a gate of a drive FET Q2 and it is operated in a sub threshold region. On the other hand, a source of the load FET Q1 is connected to a drain of the FET Q2 via a diode D1 and the gate is directly connected to a drain of the FET Q2 and it is operated in the sub threshold region. Thus, it is possible to change a drain current of the FET Q2 exponentially with respect to a gate-source voltage and a drain-source circuit of the FET Q1 is changed linearly with respect to a logarithmic change in the drain current. Thus, the amplifier circuit with a large gain in a single structure is formed and the number of elements is reduced to reduce cost.
