Title: Processing method for waterless lithographic printing plate
Inventor: KOJIMA NORIYOSHI
IPC: G03F7/40
Filed: 1991-03-28
Abstract: PURPOSE:To obtain sufficient dyeing density in a short time by exposing the waterless lithographic printing plate, and then performing a developing process and dyeing the plate in the presence of an irradiating ultrasonic wave. CONSTITUTION:After the waterless lithographic printing plate formed by laminating a primer layer, a photosensitive layer, and an ink repellent layer on a substrate in order is exposed, the developing process is carried out and the printing plate is dyed while irradiated with the ultrasonic wave. The amplitude, frequency, etc., of the irradiating ultrasonic wave can be controlled to optimum values according various conditions such as the thickness of the layer of the lithographic printing plate, the temperature and density of dyeing liquid, and the extent of deterioration. Sufficient dyeing density can, therefore, be obtained by the processing of the waterless lithographic printing plate in a short dyeing time and homogeneous dyeing effect can be obtained without using any special stirring device, etc. Further, the dyeing effect is promoted to reduce the amount of dyeing liquid.

Title: Clock generator
Inventor: MIYOSHI YOSHIRO
IPC: H03K5/00
Filed: 1988-04-12
Abstract: PURPOSE:To obtain a clock output with a frequency of a small error with respect to the set frequency by providing 1st and 2nd reference oscillators with two frequencies, 1st and 2nd programmable frequency dividers, a gate circuit and a flip-flop. CONSTITUTION:The time till a flip-flop 22 is set from it is reset depends on the frequency division ratio of the 1st reference oscillator 11A and the frequency division ratio of the 1st programmable frequency divider 15A and the time till the flip-flop 22 is reset from it is set depends on the oscillated frequency of the 1st reference oscillator 11B and the frequency division ratio of the 1st programmable frequency divider 15B. Thus, the output period of the flip-flop 22 depends on the combination of the oscillated frequency of the 1st and 2nd reference oscillators 11A, 11B and the frequency division ratio of 1st and 2nd frequency dividers 15A, 15B. Thus, even when low oscillated frequencies of the 1st and 2nd reference oscillators 11A, 11B are used, the frequency error obtained as a clock output 25 is small with respect to a desired frequency.

Abstract: PURPOSE:To smoothly and effectively return from a step-out of a linear motor by stopping the correction of a current waveform pattern while the phase difference between a current  waveform pattern and an output of position detecting means exceeds the prescribed value and during the predetermined time thereafter. CONSTITUTION:A speed arithmetic unit 3 serves to obtain the prescribed distance passing time TL from a position signal 1, and a sinusoidal wave generator 5 serves to form a sinusoidal wave corresponding to 180 deg. at the current angle for the time TL.

A position correcting unit 4 serves to correct the time TL by the phase difference TP. A step-out processor 8 closes a timer contact of a phase difference detector 6 when the phase difference TP exceeds the prescribed value, and opens a ready signal simultaneously. Thus, the return from the step-out can be smoothly performed.
