IPC: G01P15/125
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To provide a multiaxial accelerometer which suppresses a difference in the sensitivity of the detection of an acceleration between respective directions. SOLUTION: A first substrate 21, a semiconductor substrate 22, a weight-part substrate 23 and a second fixed substrate 24 are laminated and bonded sequentially. A moving electrode 25 is elastically supported by the semiconductor substrate 22 via beam parts 26 at the inside of an inside frame 22a. A weight part 28 is connected to the rear surface of the moving electrode 25. At this time, the thickness of the weight part 28 is made thicker than the thickness of the thick part of the moving electrode 25. Thereby, the position of the center of gravity of a moving part in which the moving electrode 25 is added to the weight part 28 is separated with reference to the electrode face of the moving electrode 25 as the center of a swing, and a moment is increased. Even when the moving part is subjected to the same acceleration, the swing amount of the moving part is increased.  The distance between electrodes and a capacitance which is generated across the electrodes are changed largely, and the sensitivity of the detection of an acceleration in the X-axis direction and the Y-axis direction whose sensitivity is low in conventional cases is increased.

Title: Screw tightening method for industrial screw tightening robot
Inventor: IMAHASHI SATORU
IPC: B23P19/06
Filed: 1993-03-26
Abstract: PURPOSE:To provide a screw tightening method by which high torque can be prevented when a work or a screw is seated by carrying out divided pattern control on a temporary tightening process to tighten the screw inward and an additional tightening process to additionally tighten the screw in an industrial screw tightening robot to carry out pattern control to tighten the screw firmly. CONSTITUTION:When an industrial screw tightening robot is started, it moves to a screw tightening point, and enters operation of a temporary tightening process. After operation of the temporary tightening process is finished, it judges whether a screw is seated or not, and when the screw is not seated, it outputs a screw tightening error. When the screw is seated, it enters operation of an additional tightening process, and tightens the screw further up to prescribed torque. Thereby, since it has divided pattern control of temporary tightening and additional tightening, self-judgment on tightening becomes possible, so that highly reliably and highly accurate screw tightening can be attained.

IPC: G02F1/35
Filed: 1994-03-11
Abstract: PURPOSE:To provide a cubic nonlinear optical material which is applicable to optical elements and has a high cubic superpolarization rate gammazzzz. CONSTITUTION:The cubic superpolarization rate gammazzzz (0; 0, 0, 0) in the case an electron-acceptive substituent (A) or electron-donative substituent (D) is imparted to some of the side chains of fix carbon atoms of hexatriene is calculated by changing the ion potential of the carbon atoms by +epsilon in the case of D and by -epsilon in the case of A. Further, the cubic superpolarization rate gammazzzz (-omega; omega, omega, -omega) of the case where the light is made incident, is calculated. Consequently, the fastest increase in the value of gammazzzz (-omega; omega, omega, -omega) with increase in the energy of photon takes place when the side chains of the carbon atoms from the second to the fifth place are successively arranged as A, D, A, D (ADAD type). Even more, the value of GAMMA (-omega; omega, omega, -omega) of the ADAD type in a non-resonance frequency region increases to about 1.7 times of that of the type in which the side chains are not substituted.
