Title: Ink supply device
Inventor: KURASHIMA NORIHIKO
IPC: B41J2/055
Filed: 1987-04-14
Abstract: PURPOSE:To inhibit the fluctuation of pressure in the ink contained in an ink supply tube which occurs when a head is scanning, accelerating, or decelerating and to prevent an ink drip from being unnecessarily discharged out of a nozzle and a bubble from being fed into a flow path, by providing a fluid control valve consisting of a film serving as an ink supply path closing valve and a spheroidal movable element having a function of deforming the film. CONSTITUTION:A fluid control valve 8 consists of a holder part 12 containing a spheroidal movable element 11 made of a rigid body and an ink flow path closing part 14 which is provided with an ink flow path and partially made of a deformable polyethylene film 13. When a head 5 is scanning at a constant speed, the movable element 11 is positioned at the center of the holder part 12, thus never closing the ink flow path. When the head in the quiescent condition starts scanning, or returns in the reciprocating scanning, an acceleration occurs in the head 5. Then, the movable element 11 presses the polyethylene film 13 and is held in this state, thus cutting off the ink flow path.

Title: Throttle valve return device for internal combustion engine
Inventor: KONO YOSHIYUKI
IPC: F02D9/02
Filed: 1993-04-19
Abstract: PURPOSE:To aim at ensured prevention of abrasion between return spring windings. CONSTITUTION:The outer circumferential surface of a cylindric bushing 4 provided on the inner circumferential side of a coil-shaped return spring 3 has a helical protrusion 4a formed thereon. This protrusion 4a is formed so that it may interpose between the winding of the return spring 3 when the throttle valve 1 is fully opened. For this reason, the throttle valve 1 opens and the winding can be positioned between the protrusion 4a at all times even when the return spring 3 contracts to its bore diameter. Thus mutual scouring of the windings can be prevented for a certainty and abrasion prevention between the windings can be attempted.

Abstract: PURPOSE: To obtain a prosthesis for transplanting an artery having a thin wall and slight taper by inserting a slender ultrasonic wave horn into a flexible tube without taper, extending the flexible tube by oscillating the horn, moving the flexible tube on the horn by heating the tube, and cooling the flexible tube at a desired position. CONSTITUTION: A power source 2 is on, and a flexible tube 12 is made at a desired length by slowly pulling or guiding a tube 12 along on an upper end of ultrasonic wave horn 8 with a taper. Since the horn 8 is oscillated toward mainly in the axial direction of the horn 8, a force of inflating in the radial direction against the tube 12 is rapidly actuated while guiding movement of the tube 12 along on a mandrel with the taper. By means of the movement, the tube 12 is inflated and heated, and an inflation of the tube 12 is further accelerated by heating. After the tube 12 of a desired length is moved on the horn 8, the horn 8 is made as a non-exciting state, and then the tube 12 is hardened by cooling. Next, the horn 8 is put in a exciting state again, and the tube 12 is loosened against the horn 8, then the tube 12 is pulled out from an end of the horn 8 with the taper.
