Title: Bidirectional optical spatial transmission device
Inventor: TAKASHIMA YUJI
IPC: H04B10/11
Filed: 1999-09-21
Abstract: PROBLEM TO BE SOLVED: To secure a high-precision tracing function even if the intensity distribution of receive light becomes ununiform owing to perturbations in the air. SOLUTION: An angle error detection optical system 30 is driven and set with a movable mechanism 29 so that the spot diameter of a received beam on an optical detector is nearly equal to the minimum resolution size of the optical detector. The X-axial received power difference at this time is (PX+-PX-) and the Y-axial received power difference is (PY+-Py-). Even when the intensity distribution of the received beam varies owing to perturbations in the air, the received power differences do not vary because of the spot diameter equal to the minimum resolution of the optical detector. Transmitted light can, therefore, be sent in the arriving direction of the received beam without tracking deviation.

IPC: H05B3/20
Filed: 1989-10-13
Abstract: PURPOSE:To obtain a stable heating element by providing an insulating substrate, a metal conductor pattern and a coat of heat resistant polymer. CONSTITUTION:A paste of Cu and the like is printed and baked on an insulating substrate 1 of alumina and the like to provide a conductor pattern 2, and a current is made to flow through the conductor pattern 2 via a lead wire 3.

Filed: 1989-10-16
Abstract: PURPOSE:To allow an object side to recognize the residual time of a self timer without providing additional parts by arranging a means displaying the detected result of input sound in front of a camera and constituting such that the residual time of the self timer is displayed by the same display means. CONSTITUTION:The means displaying the detected result of input sound pressure is arranged in front of the camera to constitute the camera in such a way that the residual time of the self timer is displayed by the same display means. For instance, when the self timer is set, an LED displays a residual time of 10 - 6 seconds by flickering vertically to inform the object side that the self timer is currently operating. When the residual time comes to five sec, all the LEDs 1 - 5 light up, when the time comes to four seconds, four LEDs light up, and when the time comes to three seconds, three LEDs light up. Namely, as the residual time decrements, the LEDs go off one by one, and when the time is up, all the LEDs go off. Under the simple constitution, the residual time of the self timer can be surely recognized by the object side.

IPC: G11B27/28
Filed: 1986-11-13
Abstract: PURPOSE:To rapidly and exactly perform a program searching by detecting the position of a video head in the longitudinal direction of a magnetic tape as an absolute position in using the beginning of the winding of the magnetic tape as a reference simultaneously with the start of the travel of the tape from a wound state at the time of loading a tape cassette. CONSTITUTION:A control circuit 5 is provided with a counter, and this counter counts a reel pulse R, and at the same time, is reset to zero by a winding tape beginning signal St, and is cleared to zero by a tape not yet loaded signal E. At the time to search the head of a desired recorded program, an absolute counter value (set value Ns) to show the record beginning position of the desired recorded program, is set in a setting circuit 6. By this program searching operation, a change-over switch 2 is switched to P-side, and simultaneously, the magnetic tape is brought into a half loading state that is abuts on a control head but not on a cylinder, and starts a high speed travelling. Then, in the control circuit 5, the reel pulse R is supplied and counted by the absolute value counter, and the absolute value Na outputted from the absolute value counter is compared with the set value Na of the setting circuit 6.

Title: Device and method for controlling step-motor and timer
Inventor: KOJIMA HIROYUKI
IPC: G04C3/14
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a controller which can further reduce the electric power consumed at the time of driving a step-motor housed in an electronic wrist watch, etc. SOLUTION: The pulse signal generating circuit 25 of a controller which controls a step-motor is constituted to generate a pulse signal GPi+1 having a duty between the duties of two pulse signals GPi and GPi+2 having different duties by synthesizing the signals GPi and GPi+2 with each other in accordance with a synthesize signal CP based on a reference signal BP. Therefore, the driving power of the step-motor can be prevented from increasing, because the controlling interval for controlling the duty of the effective power of drive pulses does not become longer even when the frequency of the reference signal BP is lowered. When the frequency of the signal BP is lowered, on the other hand, the power consumption of the controller can be reduced, because the power consumption on the circuit 25 side can be reduced.
