Title: Copying sheet
Inventor: KAWABATA TOSHIYASU
IPC: G03G15/36
Filed: 1988-07-29
Abstract: PURPOSE:To prevent the leakage of secret due to recopying by enclosing an arbitrary area with continuous recognizing lines (erasure lines) by means of an image reading sensor and forming plural segments in that area. CONSTITUTION:An arbitrary area on a copying sheet S is enclosed with the continuous erasure lines LL, and erasure lines LL1 to LL4 partition the area to form two or more segments.

Further, at the time of the (n+1) field, the signal charge, which is transferred to the second transfer register 12b and read at the second timing, is successively outputted. Thus, an excellent frame still reproduced picture can be obtained without generating the wobbling phenomenon.

Title: Signal reception circuit and optical pulse reception circuit using the same
Inventor: SAEGUSA MASAKI
IPC: H04B10/07
Filed: 1990-07-20
Abstract: PURPOSE:To prevent malfunction by using an automatic threshold control circuit so as to apply peak-hold to a signal voltage superimposing a minute voltage to a divided input signal voltage using the peak hold value as a threshold voltage and comparing the threshold voltage with an input signal voltage at a voltage comparator, thereby eliminating the influence of noise or the like. CONSTITUTION:A voltage resulting from superimposing a minute voltage onto a divided input signal voltage at an automatic threshold level control circuit A is fed to a peak-hold circuit 14, in which the voltage is subjected to peak hold and a threshold voltage is obtained. Thus, when the fluctuation of the input signal voltage is generated, the threshold voltage is controlled so as to be a divided voltage compared at a voltage comparator 3 in response to a level change when the level fluctuation of the input signal voltage takes place, the production of pulse width distortion resulting from level fluctuation of the input signal voltage is prevented and a threshold voltage in response to a very small voltage is generated even at non-signal through the superimposition of the minute voltage. Thus, the influence due to noise or the like is eliminated to prevent malfunction.

Filed: 1986-08-15
Abstract: PURPOSE:To obtain a reproducing picture of high quality by generating a pulse duration modulating signal having a prescribed pulse duration when an input video signal is a maximum value. CONSTITUTION:In a comparator 4, a level of an analog converted analog video signal is compared with that of a pattern signal of a triangular wave and a pulse duration modulating signal is outputted.

Filed: 1991-07-04
Abstract: PURPOSE:To expand a photosensitive wavelength region by a method wherein a fluores cent substance is contained in an organic compound layer composed of a single layer or a plurality of layers or a wavelength conversion layer containing the fluorescent substance is formed. CONSTITUTION:A layer 1 which contains an organic compound (a charge-generating substance) which can generate and isolate an electric charge is sandwiched between electrodes 2, 3. A substance which is provided with charge-conveying power may be added to the layer 1. In this case, the charge-generating substance is not provided with any absorbing power. That is to say, a substance (a fluorescent substance) which absorbs a nonsensitive wavelength and which emitts fluorescence at a wavelength in the spectroscopic absorption region of the charge-generating substance is added. Consequently, even when the added substance is not provided with any charge- generating power singly, the wavelength is converted into the absorbing wavelength of the charge-generating substance. As a result, a photosensitive wavelength region is expanded as a whole. For example, an inorganic pigment or the like can be enumerated as charge generating substance change carrying substance is not limited to specified one. The fluorescent substance includes 4-(dicyanomethylene)-2-methyl-6-[2-(9- durolidyl)ethenyl]-4H-pyrane.
