Abstract: PURPOSE:To reduce slide friction by forming the outer peripheral surface of a cylinder part to have the same outer diameter dimension in an axial direction in a valve lifter operation temperature region, and making the gap to a cylinder bore have an appropriate value to shape the cylinder part with thermal expansion condidered. CONSTITUTION:A cylinder part 11A is formed into a tapered form wherein an opening side end part outer diameter D2 is smaller than a ceiling part side end part outer diameter D1 under ordinary temperature. The tapered form is formed by the condition of D1=D2 so that the tapered form can be thermally expanded in a valve lifter operation temperature region of 150 deg.C to form the cylinder part outer peripheral surface of a valve lifter main body 10A into a true cylinder form. That is, the cylinder part outer peripheral surface is formed into the true cylinder form having the gap of an appropriate value to a cylinder bore e1 to be formed into a form with thermal expansion considered. Consequently, the smooth sliding of the valve lifter main body 10A can be ensured, allowing long time use.

Filed: 1990-02-05
Abstract: PURPOSE:To facilitate removal of a substance to be sucked having tackiness by covering a contact part between a sucking pad and the substance to be sucked with a non-sticky sheet. CONSTITUTION:A sheetform sucking pad 7 formed of a rubbery substance is covered with a non-sticky sheet 9, and openings 10 are formed in positions located facing recessed parts 6 of a base plate 3.

IPC: B60N2/90
Filed: 1989-02-06
Abstract: PURPOSE: To eliminate or practically reduce the noises of adjusting components by not linearly but secondarily changing the velocity of mass inertia moment effective for moving a mass during the rotating action of a driving shaft. CONSTITUTION: Three pinions 13 mutually displaced just at 120 deg. are simultaneously engaged with two crawn gears 9 and 10. The angular velocity in the gear ratio of 1:1, for example, is made higher than the angular velocity of a hand knob 4 because of the selected gear ratio. During the rotating action of the hand knob 4, the mass inertia moment of the pinion 13 rotated on the 2nd crawn gear 10 for driving a mass 15 around an eccentric bolt 2 at the rotating speed of a stud bolt 14 is added to the mass inertia moment of the mass 15. Therefore, the mass inertia moment operated on the eccentric bolt 2 is smoothed for reducing the noises so as not to be noisy to generate the motion of an upper turning element connected to the eccentric bolt under adjusting the position of a backrest when there are not the mass 15 and the transmission gear system for driving it.

Title: Junction type field effect transistor integrated circuit
Inventor: MAEMURA KIMIMASA
IPC: H01L29/808
Filed: 1989-02-02
Abstract: PURPOSE:To prevent an output current from flowing to an output buffer circuit when a circuit is turned off by attaching a J-FET (junction type field effect transistor) for current limitation between a power source in the circuit at the preceding stage of an output circuit other than the output circuit. CONSTITUTION:No current flows to an output terminal VOUT until the potential of an input signal VIN goes higher by 2Vf (Vf: gate forward direction voltage of J-FET) than the potential of the output terminal VOUT when a control signal VCS2 goes to low potential even when the potential of the input voltage VIN goes to high potential. In other words, since it is Vf>Vth, it is possible to reduce the output current compared with conventional constitution.

Inventor: SUZUKI TAKUYA
IPC: H01R13/02
Filed: 1994-01-27
Abstract: PURPOSE:To provide a nonstandard wire for a connector with high reliability. CONSTITUTION:A conductive wire for a connector is formed by combining a large number of conductive wires 1 with insulators 11. A specified number of grooves 2 whose opening 3 is narrowed are spirally formed in the conductive wire 1. An insulator enters into the groove 2 to increase the contact surface of the nonstandard conductor wire 1 with the insulator, and move of the nonstandard conductor wire 1 on the inside of the insulator is suppressed. When the insulator expands by the increase in temperature during use or on soldering, the insulator is fastened from the inside and outside to a projection 4 formed in the opening 3 of the nonstandard conductor wire 1 to suppress the move of the conductor wire 1. Since the groove 2 is spirally formed, the up and down movement of the conductor wire on the inside of the insulator is also suppressed.
