Title: Disc case
Inventor: MARUYAMA MASUO
IPC: G11B23/033
Filed: 1983-09-26
Abstract: PURPOSE:To attain a disc case which prevents a damage due to oscillation and can make a device body small-sized, by providing an elastic member in a position of a disc, which faces a driving aperture part, so that the disc is de-energized to the side of the disc driving aperture part. CONSTITUTION:While the disc case is carried, a disc 1 is pressed to a lower shell 5 of the disc case by a flat spring 2, and the disc 1 is prevented from being moved freely in the case. The disc is placed on a disc motor as shown in figure. A disc motor 9 which rotates and drives the disc 1 is inserted from a driving aperture part 6 of the lower shell 5 of the disc case, and the disc 1 and the lower shell 5 of the disc case are not brought into contact with each other, and the disc 1 is rotatable in the disc case. The flat spring 2 is deformed more than carrying of the disc case to press the disc 1 to the disc motor 9. Since a spring receiver 3 is brought into contact approximately with the flat spring 2 by a point, the rotation load of the disc 1 is very low.

Title: Positioning mechanism
Inventor: YOSHIKAWA YUKIO
IPC: G02B7/08
Filed: 1983-09-26
Abstract: PURPOSE:To simplify a structure for positioning by moving a movable member for positioning beyond and end part setting position by a driving member which makes one turn, and locking it during returning operation. CONSTITUTION:When a stop aperture 3c is selected, the 1st and the 2nd electromagnets 16 and 22 are powered on and off respectively and then a driving plate 10 is rotated to rotate the movable member 3 against a spring 5 with a pin 10a. At this time, a lock part 12b already enters the operation path of the lock piece 3e of the movable member 3, and a lock part 13b for an intermediate aperture is shunted. The lock piece 3e presses down and gets over the lock part 12b with a slanting cam 3g during reciprocating operation until the movable member reaches an overrun position, but the lock piece 3e is locked by the lock part 12b by the spring 5 in returning operation. Consequently, the small stop aperture 3b is held matching with an optical axis 1.

Title: Rear projection type television receiver
Inventor: FUJIKI YASUMI
IPC: H04N5/74
Filed: 1989-07-12
Abstract: PURPOSE:To reduce a change in the brightness on the screen in the vertical direction even when the position of eyes is varied by providing a means moving a Fresnel lens being a component of the screen in the vertical direction along the screen face so as to vary the directing angle of the vertical visual field. CONSTITUTION:The television receiver is provided respectively with a Fresnel lens 1, a renticular lens 2, a reflection mirror 3, a lens 4 and a projection tube 5, and the Fresnel lens 1 is movable in the vertical direction. Thus, with the center 7 of a concentric circle of the Fresnel lens 1 shifted upward in the vertical direction with respect to the center 6 of the optical path of an optical image, the directing angle 8 of the visual field angle in the vertical direction is directed upward in the vertical direction. Moreover, with the center 7 of a concentric circle of the Fresnel lens 1 shifted downward in the vertical direction with respect to the center 6 of the optical path of an optical image, the directing angle 8 of the visual field angle in the vertical direction is directed downward in the vertical direction. Since the directing angle 8 of the visual angle in the vertical direction is made variable in this way, the change in the vertical brightness on the screen is reduced by adjusting the Fresnel lens 1 to a proper position even when the position of eyes is varied.

IPC: C10J3/56
Filed: 1984-08-27
Abstract: PURPOSE:To enable gas sealing which is safe and reliable and has resistance to a high-temperature and high-pressure gas produced, by combining a throat ring, a jacketed skirt, a jacket for packing, a skirt expansion, and a cylindrical shielding plate. CONSTITUTION:The space between the lower surface of a throat ring 2 and a throat flange 1a is hermetically sealed with an 0 ring 4a to prevent leakage of a produced gas; the space between the upper surface of the throat ring 2 and the lower surface of a throat liner 5 is hermetically sealed with an 0 ring 4b to prevent leakage of the produced gas; and the space between the upper surface of the throat liner 5 and a packing seat 7 is hermetically sealed with a sealing packing 6 to prevent leakage of the produced gas. Thus the leakage of the produced gas through these spaces are prevented. The pressure of the sealing packing 6 against the throat liner 5 can be determined arbitrarily and to give the optimum condition by means of a packing cylinder 10. Since the upper surface of the throat ring 2 is in contact with the lower surface of a skirt 14, a metal drop or a slag drop will hardly enter through the space.

Filed: 1991-07-19
Abstract: PURPOSE:To prevent the deterioration in the opto-electric conversion characteristic of a light receiving element by branching an optical input signal to suppress the light input intensity of each light receiving element. CONSTITUTION:An optical input signal 10 is inputted to an optical branch section 11, in which the signal is branched into n-sets of optical signals and each optical signal is converted into electric signals 31-3n by light receiving elements 1-n. Then output signals of the n-sets of light receiving elements 1-n are summed by an adder 12, from which an electric output signal 40 is obtained. In this case, the input optical intensity of the light receiving elements 1-n is decreased by setting properly the branch number (n) of the optical branch section 1 thereby preventing the deterioration in the opto-electric conversion characteristic.
