Title: Variable frequency signal generating method
Inventor: SAKAI RYOICHI
IPC: H03B28/00
Filed: 1991-11-21
Abstract: PURPOSE:To prevent occurrence of jitter regardless of the value of address interval data by revising total number of addresses of a memory means storing digital data when the total number of addresses of the memory means storing the digital data is not exactly divisible. CONSTITUTION:A controller 34 sets an oscillating frequency of a variable frequency oscillator 30 to a prescribed frequency F1. Then an address interval N is set in response to an output frequency Fg. Then whether or not the address total number M of a memory 16 is exactly divisible by the address interval N is judged. When the result of judgement indicates a negative result, the address interval is revised into a number P which is larger than the address number N and by which the total number M is exactly divisible. Then a clock frequency F2 to obtain a desired output frequency at the interval P is obtained and the memory 16 is read out of each address P by using the clock frequency F2. Thus, a signal deviated from the Nyquist's theorem is generated stably without jitter regardless of the value of the address interval data.

Title: Driver for liquid crystal display device
Inventor: NAGASHIMA NOBUYOSHI
IPC: H04N5/10
Filed: 1988-12-29
Abstract: PURPOSE:To prevent the lowering, etc., of display quality caused by an erroneous video signal by adding a correcting circuit to correct the error to a state equivalent with a case that an erroneous first synchronizing signal is not generated even when this erroneous first synchronizing signal to be overlapped with a succeeding second synchronizing signal is generated. CONSTITUTION:When an erroneous synchronizing signal RES is outputted from a synchronizing signal generation circuit 81 after one field that one synchronizing signal RES is outputted, an output (f) of a D-flip flop 87 is kept to a high level from the rising time of a signal (i) to falling time in a part where the first synchronizing signal RES is outputted. Thus, the signal (f) is operated as masking and the error is corrected. Accordingly, even in case of malfunction that the synchronizing signal RES is outputted for each field, a corrected signal RES 1 is generated only for each frame.

Title: Laser beam writing unit
Inventor: DATE NOBUAKI
IPC: G02B26/10
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To improve an image by disposing a vibration damping means of specified structure in a vibration transmitting passage between a turn back mirror and the drive means in a printer body so that double floating emerges in the passage transmitting a vibration from a shaking source to the turn back mirror thereby damping the vibration sufficiently. SOLUTION: The laser beam writing unit comprises an optical stay 1, a laser scanner 2 and a plate 3 for supporting a turn back mirror 5. Vibration from a shaking source, e.g. a main motor, begins to propagate toward the turn back mirror 5 through the optical stay 1 but it is absorbed by a rubber sheet 11 and damped before being transmitted to the mirror supporting plate 3. It is further absorbed by a rubber damper 8 before being transmitted to the turn back mirror 5 through an angle adjusting screw 10. Consequently, the vibration is not transmitted substantially to a mirror reinforcing frame 6. Furthermore, a weak vibration causes no resonance because eigen frequency of the turn back mirror 5 is shifted to a preferable range by means of the mirror reinforcing frame 6.
