Title: Private branch common reception system and branch device
Inventor: YAMASATO AKIKO
IPC: H04N21/647
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively improve a private branch common reception system transmitting a broadcasting signal from a ground station to a plurality of reception terminals so that the system may transmit a broadcasting signal from an artificial satellite to the reception terminals. SOLUTION: AMP 50 for amplifying a reception signal flowing on a branch route from a branch circuit 30 to a branch terminal TBR is arranged in a serial unit which is serially disposed on the transmission line of the common reception system to branch and output the reception signal to the respective reception terminals. Besides, DC power inputted from a BS tuner or the like to the branch terminal TBR is separated by PSF 80 and a DC constant voltage for driving AMP 50 is generated by AVR so that power source is supplied to the AMP 50.  When an existing system for the ground station is changed into the one capable of receiving a satellite broadcasting, serial unit at the side of the reception terminals where the level of the reception signal becomes lower than a proper level in the case of transmitting the reception signal from a BS antenna to the transmission line of the system is converted into the serial unit.

IPC: F16C33/66
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To prevent oil mist from adhering to the mirror surface of a rotary polygon mirror and to prevent the lowering of reflectance and the dispersion of the reflectance on the mirror surface by concentrically attaching an air current generating member to the lower part of a rotary polygon mirror supporting member so that a ball bearing may be covered with the air current generating member. SOLUTION: The air current generating member 5 is concentrically attaching to the lower part of the rotary polygon mirror supporting member 2 so that the ball bearing 7a may be covered with the member 5. An air current generating part is provided on the inner surface of the circumference of the member 5 and a blade element is arranged so that a generated air current may be in an opposite direction to the direction of the center of rotation of a rotor 6. The oil mist resulting from the lubricant of the ball bearing 7a evaporated due to temperature rise associated with the rotation of the rotor 6 is guided by the air current in the opposite direction to the direction of the center of rotation of the rotor 6 which is generated by the blade element and carried to the inner surface of the circumference of the member 5.  Therefore, the oil mist resulting from the lubricant of the ball bearing 7a is prevented from adhering to the mirror surface 1a of the rotary polygon mirror 1.

Filed: 1984-06-29
Abstract: PURPOSE:To obtain the photomagnetic head which has a high quenching ratio and performs reproduction with a high S/N ratio by making the main axis of optical anisotropy of a lens coincident with the plane of linear polarization of a laser beam. CONSTITUTION:Irradiated laser beam passed through a prism 3 is P polarized light which has the plane of polarization in the paper surface. The plane of polarization of reflected light from a vertically magnetized film 6-1 provided to a disk is rotated by an angle thetaK of Kerr rotation throug Kerr effect and this rotation varies the quenching ratio. The polarization state of light passed through the lens is not linear polarization, but elliptic polarization having the main axis rotated. The quenching ratio varies at 180 deg. intervals of the angle of rotation of the lens, the axis of anisotropy of the lens coincide with the plane of linear polarization of incident laser light at an angle at which (quenching ratio)<-1> is minimum, and the axis is set to a lens rotation angle which is about 45 deg. different from said angle, the anisotropy of the lens is felt largest and (quenching ratio)<-1> increases. Consequently, when a stop-down lens 5 is incorporated in the photomagnetic head, (quenching ratio)<-1> is minimum and information reproduction with a high S/N ratio is performed.

Title: Microimage projector
Inventor: KAMIMURA KUNIAKI
IPC: G03B21/11
Filed: 1988-05-30
Abstract: PURPOSE:To obtain a variable power over a wide range by fixing a first lens to a movable body moving between a film and light source so that it can freely move, and providing a second lenses in such a way that the first lens coincides with an optical axis and the second lenses is capable of moving independently. CONSTITUTION:The light source 7 and the first and second condenser lenses compose an illuminating optical system. The first lens 71 is fixed to the movable body 69, and the second lens 72 can independently move on the optical axis by means of a rack 73 and pinion 77, with the lens 71 coinciding with the optical axis. When the movable body 69 is moved, the position of the illuminating optical system is varied between the film and light source 7, with the gap between the lenses 71 and 72 constant (with the composite focal length constant). When the only second lens 72 is moved without changing the position of the movable body 69, the gap between the two lenses are varied, thereby altering the composite focal length. This varies the degree of condensation and obtains the variable power with a sharp image over a wide range; therefore, an image can be projected.
