Title: Digital pll circuit system
Inventor: MURATA KATSUJI
IPC: H03L7/06
Filed: 1981-03-31
Abstract: PURPOSE:To decrease the time for phase synchronism, by variably setting the number of counts of an up-and down-counter with a phase difference information output from a phase detecting circuit. CONSTITUTION:An up-and dwon-counter 2a can variabley set the number of counts by count-up as a loop filter. A phase detection circuit 7 detects the phase difference betwen an input timing signal A and an output frequency G of a variable frequency divider 5a constituting a digital voltage controlled oscillator 6 and outputs a signal corresponding to the phase diffeence. Based on the phase difference output from the circuit 7, the number of counts of the counter 2a until count-up can variably be set. Thus, the function of the loop filter can not be lost and the time for phase synchronism can be decreased.

Title: Cam drum stopping mechanism for operating rod type machine gun
Inventor: YOSHIMATSU MORIYOSHI
IPC: F41A17/42
Filed: 1995-01-30
Abstract: PURPOSE: To alleviate the impact force at the time of forcibly stopping a cam drum. CONSTITUTION: A stop member 17 having an engaging hole 19 is fixed to a cam drum shaft 12 via a spring bush 20. When an operating rod 2 is arrived at the forward position, a locking mechanism 24 is operated, a lock pin 25 protrudes to be brought into contact with the side of the member 17. If a bullet is shot, the pin 25 is retracted to be separated from the member 17, and not engaged with the hole 19, and hence the member 17 is not locked, and a cam drum 3 is continuously rotated. If the bullet is not shot, the pin 25 is brought into contact with the member 17, engaged with the hole 19 when the hole 19 is arrived at the opposed position immediately after the percussion, and the member 17 is locked. Thus, the frictional force by the bush 20 is operated as the brake force at the shaft 12 to stop the shaft 12, i.e., the drum 3 while decelerating it.
