Abstract: PURPOSE:To stabilize a wavelength and to decrease variation in laser output, by utilizing two etalons so that one is controlled from a result of spectral diffraction of a laser beam while the other is controlled from laser power. CONSTITUTION:A divergent component produced from a laser beam by an integrator 12 is spectrally diffracted by an etalon 13 and one-dimensional distribution of optical intensity is measured by an image pickup element. 15. The measured data is smoothened and subjected to image processing 16 to obtain a position (x) presenting a maximum intensity. The position (x) is compared with a designated positional coordinate (x0) corresponding to an indicated wavelength, and a fine control etalon 5 is controlled by means of a servo mechanism from a result of the comparison, so that the central wavelength lambdam2 in a transmitting region of the etalon is varied. The fine control etalon is regulated in this manner, whereby an oscillation wavelength of the laser can be held fixedly. A part of the laser beam 6 is guided to a power monitoring mechanism 9. It is determined whether a laser output is increased or decreased when a rough control etalon 4 is controlled in either direction. The rough control etalon 4 is regulated by the servo mechanism 11 so that a maximum laser output can be obtained.

Abstract: PURPOSE:To continuously access a memory when a request for using another CPU is not outputted after once accessing the memory from one CPU by providing the titled controller with a prescribed timing generating circuit and a memory use request detecting circuit. CONSTITUTION:The timing generating circuit 12 generates timing signals 21-24 for sequentially testing the existence of a memory use request from the CPU and applies the signals 21-24 to a latch circuit 10. On the other hand, the memory use request detecting circuit 17 checks a using request from the other CPU when one CPU completes the access of the memory, detects the using request from the other CPU and applies a detecting signal to the latch circuit 10. If using request signals 5b-5d from the other CPU are not generated, the CPU connected to a use acknowledge signal 6a can be allowed to access the memory continuously without queuing while turning on/off a using request signal.

Abstract: PURPOSE:To obtain a stable and highly accurate address mark detection circuit by combining a counter and a flip-flop circuit through the aid of using a clock signal, being used in a disk device. CONSTITUTION:The address mark part of a prescribed byte length to show the beginning of an address part in a format is detected by the combination of the counters 16, 17 and the flip-flop circuits 19, 20, through the aid of using the clock signal, for instance, a read clock signal or a reference clock signal or the like. Namely, when by counting-up the counter by the clock signal in the disk device, the address mark part of the specified byte length designated by the format is found during a period that an address mark search signal is in ON-state, an address mark detect signal is outputted. Thus, without using a resistor and a capacitor, the highly accurate and stable address mark detection circuit can be obtained by a logic circuit.

Abstract: PURPOSE:To enable a register to have data holding functions by itself and also to decrease the number of component transistors to attain a high degree of integration with a semiconductor storage device, by using a latch circuit combined with CMOS inverters to constitute a data register of a SAM part. CONSTITUTION:Data are already read out of a memory cell together with bit lines 1 and 2 set at H and L respectively. When a data transfer signal 7 is set at H, both transistors TRQ7 and Q8 are turned on. Thus the data are supplied to a data register 30. Here TRs Q11 and Q10 are turned on and TRs Q9 and Q12 are turned off respectively and therefore nodes N3 and N4 are set at H and L respectively. Then the data are fetched by the register 30. When a selection signal 9 sent from a selector is set at H, the data are outputted to a serial output bus. In such a way, the input data can be held by a latch circuit provided in the register 30. Furthermore, the number of transistors constituting the semiconductor storage device can be decreased and therefore a control signal is simplified.

Abstract: PURPOSE:To insulate a measuring part completely and enable highly precise measurement with ease, by transduing a current to be measured flowing through a current measuring shunt into an optical signal and transmitting the same to the measuring part through an optical fiber. CONSTITUTION:When a current I to be measured flows through a shunt 1, a current IL proportional to the current I flows through a light-emitting diode 2, which delivers an optical signal having the illuminance proportional to the current IL. This optical signal is transmitted to the light-receiving diode 6 of an optical signal receiving part B and transduced therein into a voltage signal proportional to the illuminance. Then, an amplifier 7 removes a voltage corresponding to a base current made to flow through the light-emitting diode 2 by supplying a bias voltage, and supplies a voltage signal proportional to the current to be measured to a measuring part 8. By this constitution, a current in a high- voltage part can be measured without being restricted by an insulation level and, in addition, the effect of noises can be eliminated.
