Title: Image forming apparatus and copying apparatus
Inventor: NAKAYAMA TOMOFUMI
IPC: H01S3/10
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To protect a laser optical source from breakdown by cutting off a current flowing in the optical source according to a first effective comparison output provided only in a sample state of a sample holding means for sample holding a detected light quantity value and a second effective comparison output only in a hold state. SOLUTION: Only in the through-state of a sample holding circuit 62 (65), i.e., in a control period of a sample state, the output of the sample holding circuit 62 (65) is compared with a limit voltage outputted from a limit voltage hold circuit 83 (93). When the output of the sample holding circuit 62 (65) is higher than the limit voltage, a comparator circuit 82 (92) goes to a HIGH output voltage level which is inputted to a logical sum circuit 84 (94), and a switch 71 (72) of a total current source 52 (55) turns off to cut off a current to be fed to a semiconductor laser 59 (60). During holding of the sample holding circuit 62 (65), the comparator 82 (92) is inhibited from operating.

Title: Phase comparator
Inventor: FUTAGAWA YOSHIKIYO
IPC: H03K5/26
Filed: 1987-11-10
Abstract: PURPOSE:To obtain an accurate phase difference signal by retarding a reset signal of an AND gate generating a reset signal through one or two consecutive DFFs or more to operate a DFF pair stably. CONSTITUTION:When twin delayed flip-flops(DFFs) 2, 3 are both at logical 1 with signals f3, Fc incoming, an AND gate 5 outputs this state. The output signal is retarded through DFFs 10, 11 operated at a high frequency f0 into a reset pulse, then the reset pulse is generated with a delay of at least one period of the frequency f0 after the twin DFFs 2, 3 goes to '1'. Thus, the level of the twin DFFs reaching logical 1 with a delay has a firm width and no failure in resetting is caused. In this case, affirmative and negative outputs are ANDed by AND gates 12, 13 to obtain a lead/lag phase difference. Thus, the phase comparator with complete operation and high speed response without steady-state error is obtained.
