Title: Tracking device for dat
Inventor: YOKOYAMA YOSHIHIKO
IPC: G11B15/467
Filed: 1990-01-22
Abstract: PURPOSE:To suppress the variance of the gain of tracking servo even in the case of the difference of the level of the pilot signal, which is recorded at the time of sound-recording, between recorders by detecting the recording level of the pilot signal scanned at present and adjusting the gain of a servo loop based on this detected level. CONSTITUTION:A sampling pulse SP2 obtained by delaying a sampling pulse SP1, which is outputted at the time of detecting a synchronizing signal recorded in an ATF(automatic track finding) area, by a prescribed time is delayed by the same time to generate a sampling pulse SP3, and the level of the pilot signal recorded on a track traced at present is kept by this sampling pulse SP3. The loop gain of the feedback control is adjusted in accordance with the kept level of the pilot signal. Thus, the variance of the gain of tracking servo is suppressed though the level of the pilot signal recorded at the time of sound-recording is different by recorders, and the disturbance of head tracking for reproducing is eliminated to prevent the degradation of the error rate and sound breaks due to detracking.

Abstract: PURPOSE:To automatically easily position a photodetector array to improve the precision of positioning by setting the photodetector array to the position, where is determined in accordance with image data obtained from the photodetector array and preliminarily set image data, by a moving device. CONSTITUTION:Image data from a photodetector array 4 is written in a memory 31 and is compared with preliminarily set image data to calculate the deviation in the direction of an arrow E or F of the photodetector array 4.

When the deviation is within the prescribed range, adjustment for rectangularity of the photodetector array 4 is completed. Then, a substrate 5 is fixed to a case 1 by screws 27 and 28. Thus, focusing of an optical unit and positioning of the photodetector array are automatized.

Abstract: PURPOSE:To reduce the manufacturing cost of a printed wiring board by making a through hole in a board and providing a conductive layer of hardened conductive paste on the inner peripheral face of the through hole. CONSTITUTION:A through hole 2 is made in a board 1 and a pin 7 is inserted therein. A screen 8 is superposed on the surface of the board 1 and the gap between the inner peripheral face 3 of the through hole 2 and the pin 7 is filled with a conductive paste 5 which is eventually hardened to form a conductive layer 6.

Filed: 1980-02-04
Abstract: PURPOSE:To improve the responsibility to a transmission request of high priority, by providing the priority to the transmission request and giving priority for processing to the request in the order of higher priority. CONSTITUTION:The transmission request message is received from the communication controller CCU3 of the terminal device T2 by the line control circuit 2b. Then a comparison is given at the priority control circuit 3 between the priority PR within the control field of the reception transmitting frame and the priority under transfer. In case the PR of the reception data is higher than that of under transferring, this is informed to the line control circuit 2b from the priority control circuit 3. The circuit 2b transfers the received message to the memory 5 and then informs a reception of message to the common control circuit 4. The circuit 4 of the controller CCU1 reads the received message out of the buffer 5 and then decodes it, and then sends a message to the controller CCU2 of the terminal device T1 to indicate a temporary holding of the transmission of data to perform necessary process. After this, the transmission data is sent to the controller CCU2 which is held up to present.

Filed: 1988-01-25
Abstract: PURPOSE:To ensure the stabilized constant current characteristics despite the repeating cut-off of a load by connecting a dummy load in parallel to the load to secure connection of the dummy load when the load is cut and therefore keeping the temperature of a current detecting resistance at a constant level. CONSTITUTION:The current flowing to a focusing lens coil 3 is turned on and off by a relay 24 according to the plotting procedure in an electronic beam plotting device. When the coil 3 is turned off, a control computer 1 transmits a signal to a control circuit 23 to actuate the relay 24. The circuit 23 actuates the relay 24 based on the received signal and connects the relay 24 to a contact (b). Thus the current of the coil 3 supplied from an amplifier 22 is turned off. In this case, a current having a level exactly equal to the current flowing to the coil 3 is continuously supplied to a current detecting resistance 26 via a dummy load resistance 25. Thus the self-heating value of the resistance 26 has no change.
