Title: System for controlling torque of motor
Inventor: IWAGANE TAKANOBU
IPC: H02P29/00
Filed: 1988-11-07
Abstract: PURPOSE:To perform highly precise torque braking by providing a current feedback loop and a torque feedback loop to control the generated torque of a motor in a system the load is operated through a speed reducer. CONSTITUTION:A torque detector 5 is provided to an output shaft of a speed reducer 11 to constitute a torque control loop outside the current feedback. A torque detection signal is then differentiated and by multiplying by a specified coefficient (kO), it is added to the loop. In order to compensate the nonlinearity of a spring constant, a compensatory characteristic corresponding to the torque is added to kO. This can solve both the improvement on damping and the compensation of friction torque.

Title: Electrostatic attraction apparatus
Inventor: TAKEMURA NORIYOSHI
IPC: H01L21/683
Filed: 1991-10-25
Abstract: PURPOSE:To provide an elecrostatic attraction apparatus provided with a wafer lift-off detection device which can detect that a wafer has been lifted off from an attraction stand. CONSTITUTION:An impressed voltage on an attraction stand 3 which electrostatically attracts a wafer 1 is released; after that, an electrode needle 7a, on the surface side, which energizes and come into contact with the surface 1a of the wafer 1 is raised and separated; then, the energizing force by a spring 11a at an electrode needle 8a on the rear side is a wafer 1 from the lower part. When a residual attraction force between the wafer 1 and the attraction stand 3 become smaller than the energizing force by the spring 11a, the electrode needle 8a on the rear side pushes up the wafer 1. The electrode needle 8a on the rear side is moved up to a position where it is supposed that the wafer 1 has been lifted off from the attraction stand 3. Then, a stopper 8a comes into contact with an electrode 12d. This contact is monitored electrically, and it is detected that the wafer 1 has been lifted off.

Filed: 1988-11-05
Abstract: PURPOSE:To form a pocket to prevent stool from leaking from the side of a diaper by outwardly turning the diaper at the middle of the projection length of a longitudinal end of a barrier cuff. CONSTITUTION:The cuff sheet side edge of a barrier cuff 10 is stuck by means of an adhesive (A) onto a liquid permeable sheet 2 in the vicinity of a side edge of an absorbing body. A longitudinal end of the barrier cuff 10 is turned outwardly at the middle of its projection length and its turned faces are stuck to each by means of the adhesive A. In the case of putting on the paper diaper, the barrier cuff 10 is prevented from wholly falling inwards, even when it contracts, by the shrinkage force of an expansif elastic member 12; the barrier cuff 10 is caused to stand up slightly outwardly by the longitudinal stretching force of the paper diaper. Under these conditions, the skin of the wearer B touches the diaper an the top side of barrier cuff is put down outwardly so that it is softly applied to the skin. In addition, a pocket P for loose bowels is constantly held in between the barrier cuff 10 and a liquid permeable sheet 10 by adjustment of the width of a surface sheet 20.

Abstract: PURPOSE:To reduce the weight of a piston pin by manufacturing a piston pin composed of cylindrical matrix formed by crystallized glass crystallized by heat treatment or the like and ceramic continuous fiber introduced in the matrix in such a manner as to orientate in the circumferential direction. CONSTITUTION:Crystallized glass as a matrix is glass crystallized by heat treatment, ultra-violet ray irradiation or the like and has a composition of Li2O-SiO2-Al2O3 or the like.

IPC: D03J1/06
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent the drying unevenness of a woven cloth from occurring due to the dew condensation of steam evaporated from the woven cloth on a water shielding plate and dropping thereof onto a surface roller when the woven cloth is thermally dried with a heating unit just before a cloth roller in a water jet loom. SOLUTION: This cover device in a water jet loom is obtained by installing a water shielding plate 13 and a guide cover 30 between a dehydrating cylinder 7 and a surface roller 9 at gaps 32 and 33 kept from the dehydrating cylinder 7 and the surface roller 9. Air in the gaps 32 and 33 functions as a heat insulating material without transmitting a low temperature of the water shielding plate 13 and the dehydrating cylinder 7 to the guide cover 30. Since the temperature of the guide cover 30 is kept in the vicinity of ambient temperature, the dewdrops are not dropped onto the cover 30 even when steam is brought into contact therewith.
