Title: Multiplex broadcast reception equipment
Inventor: KATO HIDEO
IPC: G01S5/14
Filed: 1995-03-09
Abstract: PURPOSE: To supply a received signal at the same time without extending antennas by inputting the received signal through an antenna and outputting it to a multiplex broadcast reception and one or more audio parts. CONSTITUTION: A distribution circuit 12 inputs the received signal of the antenna 2 through a booster 11 and distributes it to the connected FM multiplex broadcast receiving circuit 13 and a car radio set 3. At the time of this distribution, the reception level drops, so the received signal is previously amplified by the booster in consideration of the drop and then supplied to the circuit 12. Thus, the reception level is corrected by the booster 11 and then even when reception is performed in a weak electric field area, deterioration in reception state due to the distribution even to the circuit 13 in addition to the original radio set 3 is suppressed. The signal is a high frequency signal, so the booster 11 or circuit 12 needs to have the impedance matching.

Filed: 1989-03-02
Abstract: PURPOSE:To display graphic data at the optimum reduction rate automatically without varying the reduction rate and redisplaying the data by an operator by providing a reduction rate decision mechanism and deciding the best reduction rate. CONSTITUTION:Graphic data is read out of a hard disk 2 and stored in an image memory 1.

Abstract: PURPOSE:To eliminate the generation of an offset even in the shift of a lens by shifting a half mirror and a total reflection mirror after fixing them to an objective and providing a means to detect the displacement to a pit. CONSTITUTION:A half mirror 3 is set opposite rectangularly to a total reflection mirror 10, and both lenses are fixed to an objective 4 and shifted together with the lens 4. The luminous flux sent from a light source is condensed to a piy 6, and the reflected light 7 is made incident to a detector 8. The lens 4 is fixed to mirrors 3 and 10 and shifted in case the lens 4 has a delta shift of the direction A to the flux 2 and irradiate correctly the pit 6. Therefore, the coincidence is obtained between the center luminous flux 7 reflected by the mirror 10 and the luminous flux 7' having no shift. Then these fluxes 7 and 7' reach a point C on a 2-split line of the detector 8. As a result, an offset is optically eliminated even in the shift of a lens.
