Abstract: PURPOSE:To simply execute the optimal offset correction by providing a disturbance generator of a track actuator and displacing forcibly the track actuator in the track direction, and executing the adjustment so that the offset generation quantity becomes minimum. CONSTITUTION:The device is provided with a level varying device 27 for adjusting an output level of a track position detecting device 21 of an objective lens actuator 17, by adding circuit 25 for adding an output of the 1 level varying device 27 to a track servo-circuit, and a disturbance adding circuit 33 for adding a prescribed disturbance to an objective lens actuator driving circuit 31. In such a state, by adding a prescribed disturbance whose level is known in advance to, an objective lens actuator position detection level added to the track servo-circuit is adjusted. Accordingly, while monitoring an output of an addition amplifier 25 of a tracking error signal and an actuator position detecting signal, a level of an attenuator 27 can be adjusted so that a fluctuation of an offset synchronized with a disturbance level becomes minimum. In such a way, an optimal offset correction can be executed simply.

Filed: 1985-08-07
Abstract: PURPOSE:To obtain the effect similar to the effect of a nickel catalyst with which the inlet temp. of a reactor is much higher and to conserve energy by using a cobalt oxide catalyst at the specific inlet temp. of the reactor in the stage of removing a slight amt. of carbon oxide by methanation reaction. CONSTITUTION:The carbon oxide and hydrogen are brought into reaction by using the cobalt oxide catalyst at 120-250 deg.C inlet temp. of the methanation reactor in the stage of removing a slight amt. (e.g. <=1,000ppm) carbon oxide contained in a hydrogen-rich gas for chemical industry. Any of alumina, silica/ alumina may be used as a carrier for the above-mentioned cobalt catalyst. The amt. of the cobalt to be deposited thereon is preferably 10-50wt% in terms of cobalt oxide. The inlet temp. of the reactor is as high as about 320-350 deg.C in the case of the nickel catalyst but is as low as 120-250 deg.C in the case of the above-mentioned cobalt oxide; therefore the catalytic loss and thermal loss are extremely little and such catalyst is extremely advantageous in terms of energy conservator.

Title: Signal selecting circuit
Inventor: HAYAKAWA MITSURU
IPC: G06G7/12
Filed: 1985-08-07
Abstract: PURPOSE:To realize a wide-band, stable signal selecting circuit which has excellent output linearity by composing circuits of transistors (TR), current sources, and resistances. CONSTITUTION:For example, input signals to circuit blocks S1 and S2 have voltage values so that V1>V2. The collector voltage of an output TR Q13 drops and a clamp TR Q14 is turned on; and a feedback TR Q12, on the other hand, is biased reversely to turn off. Therefore, an input TR Q11 is held on and the base voltage of an output TR Q13 does not vary. The collector voltage of an output TR Q23, on the other hand, is high, a clamp TR Q24 is biased reversely to turn off, and a feedback TR Q23 is turned on and enters a balanced state when the base voltages of output TRs Q13 and Q23 are nearly equal to each other. Consequently, an input TR Q21 is turned off and only an input signal V1 appears at an output terminal O. Similarly, only the input signal V1 which has a maximum value eventually is outputted to the output terminal O.

Abstract: PURPOSE:To prevent suspension of operation of an injection molding machine, by a method wherein a quantity of an error of error register is made zero at the time of completion of dwell and the same is changed over to a torque limit value of measurement from the dwell. CONSTITUTION:At the time of completion of dwell time, when a servo-OFF signal of an injection shaft is detected by a CPU 11 for an NC, the same starts following up to an error register 25 under a state where a servomotor Ma of the injection shaft is excited, and pulse distribution is performed so that a quantity of an error turns (0).

With this construction, output torque of the servomotor Ma of the injection shaft is changed into a low value from a high value, a screw is moved backward by repelling force of resin, and the quantity of the error is increased within the register. In this instance, the quantity of the error is not accumulated within the error register, the error register is overflowed and the suspension of operation of injection molding machine does not happen.
