IPC: B65H5/06
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To quickly and positively perform skew-removing operation for paper sheets to reduce the time and cost required for skew-removing. SOLUTION: A paper feed roller 2 is composed of a driving roller 21 and driven rollers 22 in pressure-contact with the driving roller 21. The driven rollers are provided only on both side end parts of a paper sheet P so that both side end parts of the paper sheet P fed from a paper feeding roller 1 can be pressure- conveyed, or during skew-removing operation, both side end parts of the paper sheet remain, and the driven rollers are released from a pressure-contact state. The paper sheet P is fed from the paper feeding roller 1, and after the tip of the paper sheet is slightly passed through a gap-pressure part between the driving roller 21 and the driven rollers, the paper feeding roller 1 is once stopped and the driving roller 21 is reversed to remove skew of the paper sheet.

Title: Stopper nut for spectacles
Inventor: MARUI KOREHITO
IPC: F16B39/34
Filed: 1993-04-21
Abstract: PURPOSE:To provide the inexpensive nut which has a stopper function and does not damage lenses. CONSTITUTION:This stopper nut is constituted by integrally forming a resin member 3 having a threadless nut hole 4 of the same diameter as the effective diameter of prescribed internal threads 2 or the diameter smaller than the effective diameter on the rear end of a metallic nut 1 formed with the internal threads 2 concentrically with the metallic nut 1. Since the metallic nut 1 is not inserted, the sufficient tightening strength in an axial direction is assured and since the threadless hole 4 of the resin member 3 is made smaller than the outside diameter of the threads, the thread ridges are formed by a machine screw (or tapping screw) at the time of tightening and the outside surface of the screw is tightened by the elasticity of the resin material. The loosening of the screw is thus prevented. The need for the conventional T-shaped washer is eliminated and the workability of assembly is improved and the cost of assembly is reduced.

Title: Electric power amplifier
Inventor: NISHIMOTO YUTAKA
IPC: H03F1/30
Filed: 1979-10-12
Abstract: PURPOSE:To reduce crossover distortion and switching distortion by comparing a voltage at the output terminal of a variable bias system power amplifier to a reference potential between both input terminals of the 1st and 2nd amplification parts. CONSTITUTION:A reference potential developed at connection point P is compared to a potential at output terminal 22 by comparing method 19 and on the basis of its comparison result, E-C voltages of transistors 17 and 18 are controlled to prevent output transistors 15 and 16 from being cut off completely. Since transistors 15 and 16 are never cut off completely, crossover distortion and switching distortion can be prevented from appearing. In addition, since input terminals 19a and 19b of comparing method 19 are connected to balance points of bridge circuit 30 respectively, even fluctuations of idling currents of transistors 15 and 16 exert no influence upon the output of comparing method 19, and consequently the circuit extremely stable against fluctuations of temperature can be realized.

Abstract: PURPOSE:To make it possible to set the tilt of a steering wheel which is optimum for the posture of a driver, by tilting an upper column cover carrying the steering wheel, relative to a lower column cover secured to a column in association with the back and forth tilting operation of the steering wheel. CONSTITUTION:When a nut 6a is loosened by a control lever 6, a column 10 is tilted up forward about a support shaft 31 by means of a spring 16, and therefore, a steering wheel 1 is moved forward. At this time the angle of the connecting line between pins 21 on the support shaft 24 with respect to a bolt 8 on a turnbuckle 19 becomes less so that an upper column cover 3 is rotated clockwise about the support shaft 24, and therefore, the inclination of the above-mentioned steering wheel 1 is increased to facilitate the driving of a vehicle. However, in the case of that the inclination of the steering wheel is too large, the above-mentioned bolt 8 is rotated to reduce the space between the pair of pins 21 to rotate the upper column cover 3 counterclockwise about the supprt shaft 24 in order to decrease the inclination of the steering wheel 1.
