Filed: 1986-06-18
Abstract: PURPOSE:To restore from malfunction by making a low frequency oscillating circuit, pressing down the threshold level of a synchronizing separator circuit to stop a noise removing circuit, and keeping the threshold level constant when a synchronizing signal of large width is inputted from an external input terminal and the noise removing circuit caused caused malfunction. CONSTITUTION:The base of a transistor (TRS) 37 is higher in potential than the base of 26 by the partition ratio of resistors 22 and 23, and bases of TRS 28 and 36 change following base potential of the TRS 26. When the TRS 36 of a noise removing circuit is making malfunction by a synchronizing signal, there is no output signal in a synchronizing separation output terminal 79, and accordingly, a switching TRS 73 does not operate, and a low frequency oscillation terminal 81 oscillates and outputs a pulse to an output terminal 80, charges C 38 to raise base potential of a TRS 31 and makes TRS 28 and 36 off. The C 38 discharges in a current source 53, and base potential of the TRS 31 lowers and base potential of TRS 28 and 36 rises. However, as it is a peak hold type circuit, potential becomes fixed near the head value of the synchronizing signal, and synchronizing separation output is outputted to the terminal 79. As the synchronizing signal is shorter in period than the low frequency oscillation circuit, and the oscillation terminal 81 does not oscillate, pulse output of the output terminal 80 stops.

IPC: B41N1/14
Filed: 1985-06-27
Abstract: PURPOSE:To prevent the occurrence of halation in the case of formation of an image by a construction wherein titanium oxide and an organic pigment absorbing a light of specific wavelength are made to be contained in a thermosetting resin composition. CONSTITUTION:Titanium oxide and an organic pigment absorbing a light of 400-450nm are made to be contained in a thermosetting resin composition. The load of the titanium oxide is set desirably within a range equivalent to 10-50wt% of the solids content of resin in the thermosetting resin composition. It turns difficult to prevent the occurrence of halation due to a light of wavelength 400nm or less when the load of the titanium oxide is too small, while the amount of permeation thereof into the support body of a photosensitive substance increases and, as the result, the usage of a photosensitive liquid increases uneconomically when said load is too large. The organic pigment is used in an amount equivalent to 3-15wt% of the solids content of the resin in the thermosetting resin composition. It turns difficult to prevent the occurrence of halation due to a light of wavelength 400-450nm when the load of the organic pigment is too small, while an adverse effect is affected to various properties, such as the adhesion to hydrophilic and photosensitive resin, which are required by the support body.
