IPC: H04B10/532
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of photodetection by performing modulation while selecting the direction of polarization of mutually orthogonal two straight lines according to the level of binary digital signals transmitted by a transmission side, making a laser beam received by a receiver side incident on a polarizer, extracting an intensity-modulated optical signal and using the other optical wave emitted from the polarizer as a detection beam for tracking.

Title: Tracking control circuit
Inventor: KATAGIRI TOSHIYUKI
IPC: G11B21/10
Filed: 1983-10-31
Abstract: PURPOSE:To decrease the disturbing period of a reproducing picture at the start of reproduction by controlling a pilot signal generating circuit detecting a specific pilot signal to make the generated pilot signal coincident with the pilot signal of the reproduced track. CONSTITUTION:An FF34 is triggered by a leading edge of a head pulse PH generated at the start of scanning to each track of a magnetic head in a specific extraction pilot signal detecting circuit 27', an output signal SH' is generated and fed to an FF30. The output signal SH' is inputted also to an AND gate 26 constituting a specific extraction pilot signal detecting circuit 22. The signal SH' corresponding to a head switch signal SH inverted to H, L at each trace of each track is generated. Since the pilot signal generated in this way is made coincident forcibly with the pilot signal from a reproducing track, the disturbing period of the reproduced picture at the stop or at the start of reproduction from the pause is decreased. A horizontal synchronizing signal HD is inputted to an oscillator 28.

Title: Transformer
Inventor: SHIRATO JUNJI
IPC: H01F27/40
Filed: 1984-09-30
Abstract: PURPOSE:To prevent the welding-adhesion of contact and to simplify the construction by inserting a return-type heat protective element into the connecting section between the shunt winding having a capacitor of an auto-transformer and the series winding in an auto-transformer. CONSTITUTION:The shunt winding 1 has a capacitor 2 for phase advancing with parallel connection and plural taps 3 and 4 for voltage switching. The series winding 5 is connected to the winding 1. When the windings 1 and 5 are overheated with the overcurrent due to the load short circuit or the like, the heat protective element 6 opens to cut the current, thereby protecting the circuit. Then, the load is interchanged to light normally, and if left as it is, the element 6 returns to close the switch. In this case, the element will not be deposited since the charging current does not flow to the capacitor 2 through the element 6, with the element 6 closed. The circuit can be constructed at low cost since a high-voltage resistant element is not required for the element 6, and only one element is required in common for the plural taps 3 and 4.

Filed: 1991-08-15
Abstract: PURPOSE:To surely process the periodical processing request of the highest priority in a conflict arbitration system with inhibition time by setting the request inhibition time bands before and after the processing request of the highest priority and inhibiting the reception of other processing requests in those set time bands. CONSTITUTION:The processing execution mode signal generating circuits 1 are provided in number equal to the processing requests to be accepted. At the same time, an inhibition time bend 21 is set by an inhibition time generating circuit 2 based on the processing request of the highest priority. Thus other circuits 1 are prevented to accept the processing requests in the band 21. Then a circuit 1 accepts the periodical processing request of the highest priority and transmits a processing execution mode signal. The circuit 2 sets the bands 21 before and after a prescribed time point based on the time when the periodical processing request is received. Thus other circuits 1 are inhibited from accepting other processing requests.
