Title: Variable displacement type swash plate compressor
Inventor: TAKENAKA KENJI
IPC: F04B27/14
Filed: 1993-09-24
Abstract: PURPOSE:To reduce the number of part items of a compressor as well as to shorten its shaft by forming a through hole, where a swash plate connected to a rotor via a hinge mechanism is fitted in making its inclination displaceable, to allow this inclination displacement of the swash plate extending over the whole control range with a pivot center as the center. CONSTITUTION:When a swash plate 11 is rotated by a driving shaft 6, a piston 9 reciprocates in a cylinder bore 8, so that coolant gas is discharged to a discharge chamber 31 after being drawn in from an inlet car 30 and compressed. At this time, a discharge quantity of this coolant gas is controlled by pressure adjustment in a crankcase 5 by means of a control valve. For instance, if pressure in this crankcase 5 goes up, by way of example, back pressure acting on the piston 9 goes up and thereby an inclination of the swash plate 11 decreases. In brief, a ball part 16a of a guide pin 16 in a hinge mechanism K rotates and slides in a guide hole 17a, while the swash plate 11 retreats against a pressing spring 12 as making the driving shaft 6 come into contact with a support part 20b of a through hole 20 with a pivot center Y as the center.

In such a case, crosstalk occurring, e.g., in the optical switch element 18b is outputted to a dummy port 17b through an optical switch element 18e.

Filed: 1987-09-22
Abstract: PURPOSE:To correct curvature of field and ftheta characteristics at high level by combining a polygon deflector which have elliptic surfaces or elliptic cylindrical surfaces as its reflecting surfaces with a dummy cylindrical lens. CONSTITUTION:The polygon deflector 1 whose reflecting surfaces 4 are formed into the elliptic surfaces or elliptic cylindrical surfaces and the dummy cylindrical lens 3 having a cylindrical surface 5 which is arranged between the polygon deflector 1 and a scanning surface 2 and has power on a subscanning side and a curved surface of even-numbered order which has power on a main- scanning side are used.

Title: Starting sound generator of fan motor
Inventor: HATAKEYAMA ISAO
IPC: A61M21/02
Filed: 1992-09-08
Abstract: PURPOSE:To generate an environmental sound for calming infants with a vibrating plate by causing a rotor shaft to collide with a bracket and run intermittently with a fixed rate. CONSTITUTION:A rotor 3 is pushed upward by a shaft carrying spacer 6 of a bracket B so that magnetic centers of a stator and the rotor are deviated upward and held. Upon starting a fan motor 1, the rotor 3 is attracted by the magnetic flux of the stator 2 to receive a force in the direction of cancelling the deviation of the magnetic center and lowered downward against the force of the shaft carrying spacer 6. Then, a tip of the rotor shaft 5 collides with the bottom of the bracket B to generate shock sounds, which is transmitted through a motor mounting plate 7 to a vibrating plate 9 to generate vibration sounds. Upon rotating the rotor 3, the rotor 3 keeps rotating with the magnetic center coinciding with that of the stator 2 and the magnetic center is returned to the deviated condition when the fan motor 1 is stopped. When the fan motor 1 is run intermittently, the tip of the rotor shaft 5 collides with the bottom of the bracket B at every start of the fan motor to repetitively generate the vibration sounds by the vibrating plate 9.
