Title: Auto-tensioner
Inventor: SOMETA ATSUSHI
IPC: F16H7/12
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To avoid the rise of surface pressure in both the end parts of a contact part to obtain a stable damping value from direct after assembling an auto-tensioner, by forming a void for allowing the respective deformation in the radius direction inward of both the end parts, in both the end parts in the peripheral direction of the contact part of a cylindrical resin member. SOLUTION: In an auto-tensioner wherein the inner peripheral surface of the boss part 13 of a rotating member 11 is pressedly contacted to the contact part 31b of an insertion bearing 31 by the reaction force of a torsion coil spring 21 to damp the rotation of the rotating member 11 by slidly frictional force of this pressure contact when belt tensile force is increased; respective voids 32; for allowing respective deformation inward in a radius direction in peripheral direction both the end parts of the contact part 31b of the insertion braring 31, are formed on the outer peripheral side of the spindle part 3 of a fixed member 1.  Consequently, the increase of sliding resistance, between the boss part 13 and the contact part 31b, can be avoided when the boss part 13 of the rotating member 11 is pushed into the outer periphery of the insertion bearing 31 which is externally and fittely engaged with the spindle part 3 of the fixed member 1.

The first folding line 4 is provided in such a manner as to bisect the portion 3 in the longitudinal direction and two second folding lines 5 are provided near both ends each of the first folding line 4 as folding rules in the rest for chopsticks portions 3 by press working. Accordding to the perforation 2, the rest for chopsticks portion 3 is cut off, and then folded according to the first folding line 4 and the second folding lines 5 to form a rest 7 for chopsticks. At this time, both side portions of the first folding line 4 (triangular portion outside the point intersecting the second folding line) are folded and directed downward. These portions function as a support in the case where load is applied to the rest 7 for chopsticks so as to produce an effect that the rest is difficult to be broken.

Filed: 1988-12-26
Abstract: PURPOSE:To enhance yield of semiconductor wagers without disturbing a gas flow by a method wherein a wafer-loading face is inclined downward toward its peripheral part. CONSTITUTION:A wafer-loading face 17 is formed to be a protruding face inclined slightly downward toward its peripheral part. A tilt angle A of the water-loading face 17 is set preferably to 0.008 to 0.900 deg.. In order to obtain a much larger effect, it is optimum to set the angle to 0.020 to 0.800 deg..

Title: Level conversion circuit
Inventor: SHIOMI TORU
IPC: H03K19/0185
Filed: 1989-12-15
Abstract: PURPOSE:To reduce energy consumption while maintaining high-speed operation possessed by an MOS current mirror circuit by reducing a through current flowing to a circuit while maintaining the switching velocity of a specified switching element. CONSTITUTION:At a level conversion circuit 2, since the ON resistance of an NMOS transistor 48 is set larger than the ON resistance of a PMOS transistor 46, the through current is reduced by the current mirror circuit. Since the gate potential of an NMOS transistor 53 is reduced to a power supply voltage V, the through current does not flow to the NMOS transistor 53. Since the gate of an NMOS transistor 49 is connected to a connecting point n2, the gate capacity of the NMOS transistor 49 is not changed and the switching velocity of the NMOS transistor 49 is not reduced even in case the ON resistance of the NMOS transistor 48 is set large. Thus, the energy consumption can be reduced while maintaining the high-speed operation.
