Title: Original plate for electrophotographic planographic printing
Inventor: KATO EIICHI
IPC: G03G5/08
Filed: 1990-11-19
Abstract: PURPOSE:To obtain an original plate having superior elecrtrostatic characteristics, reproducing a copied image faithful to an original image and not causing the surface stain of printed matter by using binding resin contg. at least one kind of graft copolymer of a specified unifunctional monomer with a unifunctional macromonomer. CONSTITUTION:Binding resin used is a graft copolymer consisting of segments A of a polymer component protecting a hydrophilic group with a protective group contg. F and/or Si and contg. a functional group forming a hydrophilic group by decomposition and segments B of a polymer component corresponding to a unifunctional macromonomer contg. a copolymer represented by formula I. When the resin is used alone, the segments B and photoconductive zinc oxide interact properly, satisfactory electrophotographic characteristics can be maintained and microphase separated structure is formed by the difference in compatibility between the segments A, B. Since the segments a forming hydrophilic groups later are liable to exist chiefly in a surface layer, the hydrophilic property of a non-image area is more effectively improved and surface stain is prevented at the time of printting.

Title: Television signal processing unit
Inventor: HIRAUCHI YOSHIO
IPC: H04N5/92
Filed: 1986-12-26
Abstract: PURPOSE:To attain the time base correction in a MUSE decoder by using an identification signal multiplexed to a control signal part of a MUSE (satellite one-channel transmission system of high definition television) signal so as to switch the time constant of a low pass filter of a write clock generating circuit thereby changing the response speed of a time base correction circuit provided in the MUSE decoder. CONSTITUTION:The identification signal extracted by an identification signal extraction circuit 7 is fed to a write clock generating circuit 8. The input MUSE signal is converted into a digital signal by an A/D converter 9 by using a clock synchronized with the time base fluctuation of the input signal generated by the write clock generating circuit 8, and then is written in a time base correction circuit 10 comprising a storage element such as a memory, etc., by using the same clock as that for the A/D conversion. On the other hand, a time base correction circuit 10 corrects the time base fluctuation by reading a stable clock obtained from a readout clock generating circuit 12 based on the oscilation of a reference oscillator 11. Thus, the time base correction is attained at an optimum response speed with small sized hardware constitution in the MUSE decoder.
