Title: Circuit for adding artificial synchronizing signal
Inventor: KIZAKI YOSHIO
IPC: H04L7/00
Filed: 1980-12-10
Abstract: PURPOSE: To execute a smooth synchronizing operation when the synchronizing signal is detected again, by generating an artificial synchronizing signal for drop-out of the synchronizing signal.  
     CONSTITUTION: A block B extracts the synchronizing signal from an information signal T and gives it to a phase comparing circuit 1 as a reference signal of the PLL circuit of a block A. A signal which is synchronized with the phase of the synchronizing signal and has a frequency of an integral multiple of the frequency of the synchronizing signal is obtained from the block A. This obtained signal is supplied to a block C which adds an artificial synchronizing signal. If the synchronizing signal is dropped out from the information signal T, a flip-flop 12 is not set, and therefore, a shift register 9 is not reset and continues the shift operation. Consequently, an output shifted from the regular synchronizing signal by a desired clock is given from the shift register 9 to an OR gate 15. When the regular synchronizing signal is given again, the shift register is reset, and the circuit is synchronized with the synchronizing signal immediately.

Title: Laser beam oscillation device
Inventor: ENAMI TOMOKO
IPC: H01S3/137
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To feed a stabilized quality laser beam in a long term by a method wherein the positional deviation of the laser beam is detected and the position on at least one side of the positions of an output mirror and a reflecting mirror is controlled so that the position of the laser beam becomes a reference position. SOLUTION: The vertical and horizontal intensity distribution signals measured by a beam monitor 22a are taken in by a controller 23. Whether the position of a laser beam 5 is within a beam position variation allowable range or not and whether it is due to an adjustment error or not that the position of the beam 5 is not within the allowable range are judged on the basis of these taken-in intensity distribution signals. In the case where it is judged that the cause is not due to the adjustment error, actuators 24a and 24b of a reflecting mirror 3 are controlled to adjust the position of the beam 5 so that the beam position of the beam 5 becomes a reference position.  That is, a laser beam oscillation device controls the positions of the mirror 3 and an output mirror 4 on the basis of the beam position of the beam 5 and the balance of the intensity of the beam 5 to correct the positional deviation of the beam 5 and guarantees the quality of the beam 5.

Abstract: PROBLEM TO BE SOLVED: To suppress the current of a patch mode and to improve antenna efficiency by forming notches on the opposing two sides of a ground electrode, turning the structure to a crank shape and opening the ground surface side of a notch antenna element. SOLUTION: For this planar circuit type notch antenna 1, the ground electrode 3 is formed on the entire one surface of a dielectric substrate 2 in a quadrilateral shape.
