Title: Light intensity control circuit
Inventor: YOKOGAWA FUMIHIKO
IPC: G02F1/01
Filed: 1986-06-17
Abstract: PURPOSE:To stably control the light intensity by executing the control at the time of recording, based on the light intensity of a front emitted light of a light source. CONSTITUTION:In case of a recording mode, a sample holding circuit 9 becomes a sample mode at the time of reproduction, therefore, by a reproducing current correcting loop by a rear monitor, the light intensity of a laser diode 1 is controlled so as to become constant, based on a detected current of a photodiode 2. At the time of recording, a sample holding circuit 19 becomes a sample mode, therefore, by a recording current correcting loop by a front monitor, a peak value of the light intensity of the laser diode 1 is controlled so as to become constant, based on a peak value which has been detected by a peak detecting circuit 14. Accordingly, even a pickup having a scoop can control stably the light intensity.

Title: Optical disc reproducing device
Inventor: ENOMOTO AKIHIKO
IPC: G11B7/085
Filed: 1984-07-10
Abstract: PURPOSE:To prevent the characteristic of a phase compensation circuit from giving effect on a pickup feeding motor directly by providing a switch or another phase compensation circuit at the serch mode and impression of a kick signal. CONSTITUTION:In operating the serch function, the function selecting state of an operation section is detected by a control section 31. When the serch mode of the system and impression of kick signal are detected, the control section 31 turns on a switch 30. A compensating signal S1 given to a motor drive circuit 22 does not give any effect on the characteristic of a phase compensation circuit 21. A DC voltage is superimposed on a tracking control voltage CNV in the search mode and the kick signal is superimposed in a pulsive way. The DC voltage and the kick signal are given directly to a motor drive circuit 22. Then a pickup feed motor 23 drives an actuator of the pickup section without being subject to unnecessary frequency limit, feeds the pickup section to a desired position thereby improving the acurary of the feeding position.

IPC: B65H54/44
Filed: 1987-06-08
Abstract: PURPOSE:To ensure safety in the production of a package by providing a circuit for comparing the present rotating speed command value to an induction motor with a rotating speed command value in the past in a controller and taking an appropriate measure when the result of comparison in this comparison circuit is beyond a defined range. CONSTITUTION:In a winding process, the present rotation command value is compared with the value 5 sec. before in the initial period, the present rotation command value is compared with the value 10 sec. before in the medium period, and the present rotation command value is compared with the value 20 sec. before in the latter period by a comparison circuit 18. And, when the difference is within a defined width, the wind-up is continued as it is. However, if the number of pulses generated is smaller than the number of pulses to be actually generated due to the malfunction or failure of a pulse generator 9, since a feedback quantity from a PI control circuit 7 is small, an excessively large rotation command value is issued. At this time, the abnormality is judged by the comparison circuit 18 and a measure is taken such as stopping an induction motor and the like to prevent the rush-out of a package.

Title: Elastic supporting device
Inventor: ITO KAZUHIRO
IPC: F16M7/00
Filed: 1981-09-14
Abstract: PURPOSE:To obtain adequate elastic support by enabling the non-linear change and adjustment of the spring constant of a rubber supporter by a simple mechanism and operation. CONSTITUTION:In the case of changing the spring constant of a rubber supporter 13, the position of a stopper block 6 is moved, and gaps a1 and a2 between the upper surface 7 of the stopper block 6 and the upper wall surface 5 of a depression 4 are varied in the size. By this operation, the rubber supporter 3 undergoes compressive deformation and descends by a support load W. The rising point of the spring constant undergoes change at a position where the upper wall surface 5 makes contact with the upper surface 7 of the stopper block 6. Since the spring constant of the rubber supporter can be changed freely and non- linearly, the appropriate elastic support in correspondence to the using condition can be obtained.
