The diffraction grating 2 is divided into the first and the second areas 9, 10, and in the first area 9, and in the second area, the gratings are formed in the direction orthogonal to a border line of both the areas 9, 10, and in the direction parallel to the border line, respectively. The 2-split photodetector 5 is provided on a converging direction of the diffracted light of the first area 9 so that the border line direction of the photodetecting surface coincides with the border line direction of the diffraction grating 2. When the disk surface has been varied, this diffracted light moves in the direction orthogonal to the border line in the same way as the wedge prism system, therefore, by a differential output of the 2-split photodetector 5, a focal error signal can be obtained.

Filed: 1978-05-24
Abstract: PURPOSE: To reduce the power consumption when a static memory is used, by starting to pre-charge a dynamic logic circuit on detecting variation in address input signal and by sequentially ending the pre-charge according to the transfer timing of the signal.  
     CONSTITUTION: When even one of address input signals A 0  to A 11  changes from level H to L, OR-ELSE circuits G 1  to G 4  detect variation of the input signal to output at H-level signal, thereby driving pulse generating circuit 10 via OR gate G 5 . Circuit 10 generates signals (ϕ 1 ) to (ϕ 4 ) of fixed pulse width, which are used as pre-charge pulse PCP of the dynamic logic circuit. According to the transfer time of the signal, PCP is caused to fall in the order of signals (ϕ 1 ), (ϕ 2 ), (ϕ 3 ) and (ϕ 4 ) to operate digit-line load circuit 5, decoder circuits 3 and 4, input-output circuits 7 and 8, and write control circuit 9 in sequence, and consequently, memory cells are assigned so as to perform the write and read operations. Therefore, its access time becomes equal to cycle one and the need of an external clock is eliminated while the power consumption can be reduced because of dynamic logical operation.

Filed: 1987-03-17
Abstract: PURPOSE:To exactly perform tuning, by controlling the oscillation frequency of an FM local oscillation circuit so that the noise output of an FM detector can be suppressed at the minimum level. CONSTITUTION:An RF signal to be inputted to an FM front end IC2 to be tested is generated not as an FM modulation signal but a no modulation signal, and an IF signal outputted from the FM front end IC2 is inputted to the FM detector 3 whose frequency is set at a prescribed tuning frequency in advance. By constituting a method in such a way, the output of the FM detector 3 is outputted as only noise because the no modulation signal is inputted. And by controlling the oscillation frequency of the local oscillation circuit 5 connected to the FM front end IC2 so that the level of the noise can be suppressed at the minimum level, the frequency of the IF signal can be fitted to the tuning frequency of the FM detector 3. In such a way, it is possible to perform the tuning exactly even when the automization of the tuning is performed.
