Title: Two-branch diversity receiver
Inventor: AIDA FUMIO
IPC: H04B7/08
Filed: 1983-03-11
Abstract: PURPOSE:To attain a stable receiving output by attenuating a receiving electric field level of one receiver by a prescribed quantity to perform level comparison and also releasing this attenuation quantity during the time in the period of this receiver side is selected, to give a certain hysteresis characteristic to the selection switching of receivers. CONSTITUTION:Receiving signals Sa and Sb are outputted from receivers 1a and 1b. With respect to the receiving output outputted from a changeover switch 2, the signal Sa is outputted selectively before a time t11 and after a time t2, and the signal Sb is outputted selectively from the time t11 to the time t2. If it is considered that the time base is shifted in the opposite direction, that is, the time elapses in the direction from t2' to t1', the switching timing of the changeover switch 2, namely, the switching output timing of a voltage comparator 4 becomes t22' and t1' as shown by broken lines by a certain drop voltage Vx of a constant voltage element 5. Consequently, in this case, the signal Sa is selected and outputted from the changeover switch 2 before the time t22' and after the time t1', and the signal Sb is selected and outputted from the changeover switch 2 from the time t22' to the time t1' and thus, a hysteresis characteristic determined by the voltage Vx is given to going and returning paths.

Filed: 1990-02-23
Abstract: PURPOSE:To accurately determine whether it is a different system or a loop system even if the slip frequency of the different system is small by providing a phase difference change detecting element for measuring variation of phase difference between two voltages with time. CONSTITUTION:The phase difference theta between a bus voltage phase thetaB and a transmission line side voltage phase thetaL is constant in a loop system, and the timing change amount of the difference theta is zero.

When this condition is satisfied, an element 9 is output. The element 9 is satisfied, and the loop system condition is held by a flip-flop 15. Thus, a loop system AND circuit condition is satisfied, and a different system closing command is output.

Filed: 1989-02-23
Abstract: PURPOSE:To save the memory capacity to detect the movement of a picture and to reduce malfunction of movement detection due to noise by using only a low frequency component of a luminance signal so as to obtain an inter-frame difference signal. CONSTITUTION:After a low frequency component of an existing frame Fa outputted from a low pass filter(LPF) 35 is subsampled by a subsampling circuit 41, the result is fed to a subtraction circuit 42.

IPC: G11B7/1372
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To easily correct wave aberration by providing the device with a light source, a transmitting part to transmit the light from the light source, a condensing part to condense the transmitted light by the transmitting part and to focus the light on a storage medium, and further with a controlling mechanism of divergence and convergence degrees to adjust the transmitting part to control the divergence and convergence degrees of the light transmitted by the transmitting part. SOLUTION: The collimated beam generated by a collimator 20 is passed through a reflection prism and refracted by a convergence lens 51 and a solid immersion lens(SIL) 52 to condense on a storage medium 70. In this process, wave aberration exists which is caused by errors in the distance between the convergence lens 51 and the SIL 52, errors in the position of the lenses in the perpendicular direction to the optical axis, or errors in the thickness of the SIL 52. The wave aberration can be suppressed by moving a first converting lens 22 in the parallel direction to the optical axis by an actuator 30 so as to adjust the collimation degree of the collimated beam generated by the collimator 20 and to convert the collimated beam into a little convergent beam or divergent beam.
