IPC: F16F9/02
Filed: 1999-03-06
Abstract: PROBLEM TO BE SOLVED: To surely seat a moving body by evacuating air in a cylinder by a solenoid valve just before a piston abuts on a cylinder stop surface, returning the solenoid valve when the pressing force to the piston is released, and feeding air in the cylinder. SOLUTION: A piston 3 pressed to the left by a mover W compresses air in a cylinder 1, and the air of a flow determined by a flow control shaft hole 14 of a speed controller 11 flows through a solenoid valve 21, to return to an air tank through air ports A, P. A push switch 6 is turned off just before the tip of the piston 3 abuts on a piston stopper 8, so that air is released from the air port R opened to the outside, thereby surely seating the mover W. When the pressing froce of the mover W is released, the piston 3 is a little moved to the left with reaction force of a compression coil spring 7 with small stroke, so that the switch 6 is turned to connect the air port A to the air port P, so that the air opens a check valve 15 to flow in a large quantity, and the piston 3 is quickly displaced to the right or returned thereto. Accordingly, a return spring is not needed.

IPC: G11B15/61
Filed: 1990-04-19
Abstract: PURPOSE:To freely adjust the thickness of an air film to be generated between a tape traveling surface of a rotary head drum and a tape and to optimize abutting of the tape against a head by strengthening the tape tension between the drum and a reel at the time of high speed rotation of the drum and weakening it at the time of low speed rotation. CONSTITUTION:When the rotary drum 11 is rotated at high speed, a mode changeover lever 24 of a mode changeover mechanism 20 is oscillated in the direction of a dotted line as shown in the figure to be changed, and the tension of the tape 4 is increased by strengthening the tension force of a tension arm 21 of a tension coil spring 25, so as to thin the thickness of the air film to be generated between individual circumferential surfaces 11a and 14a of their respective drums 11 and 14 of the rotary head drum 10 and the tape 4. Then, when the drum 11 is rotated at low speed, the lever 24 is oscillated in the direction of what is shown by a continuous line to be changed, and the tension force of the arm 21 is diminished and hence the tension of the tape 4 is weakened, thus generating the air film with its appropriate thickness between the outer circumferential surfaces 11a and 14a, so as to improve the abutting of the tape 4 against the head.
