Title: Radiation sensor array
Inventor: TSUTSUI HIROSHI
IPC: G01T1/24
Filed: 1985-09-04
Abstract: PURPOSE:To enable a lower impedance between signal lines from a semiconductor sensor to an amplifier, by arranging a first-stage amplifier and a feedback resistance of the semiconductor sensor on the same substrate closer to each other. CONSTITUTION:In a semiconductor sensor 1, a feedback resistance 2' and an FET 3' are arranged in a array closer to each other. This enables a lower impedance with respect to an amplifier 4 between signal lines to the amplifier 4 making the array highly vulnerable to noises between lines and from outside. A higher package density of the semiconductor sensor array is possible by mounting the resistance 2 and the FET 3' alternately in stead of in a train. In this manner, a high impedance portion can be held within several mm. Thus, the sensor 1, the resistance 2', the FET 3' and the like can be formed on the same substrate to lower the impedance to a rear stage amplifier.

IPC: G03F7/004
Filed: 1993-08-06
Abstract: PURPOSE:To provide an image forming material having a uniform surface of a photosensitive layer formed by coating and having excellent storage stability. CONSTITUTION:A photosensitive layer containing a colorant is formed on a supporting body, and further, a protective film is formed on the photosensitive layer. This image forming material is exposed to light for an image and the image is transferred to an image accepting body such as paper by using difference in the adhesive property for transfer between an exposed part and a nonexposed part in the photosensitive layer. The photosensitive layer contains a diallylphthalate resin and vinyl chloridevinylacetate copolymer. Thereby, when the photosensitive layer is formed by coating, pin holes are hardly produced and the surface of the coating film is stabley formed. Further, the obtd. material has no change with time during storage and causes little trouble such as increase in pin holes or wrinkles in the photosensitive layer.

Title: Auxiliary signal transmission system
Inventor: FUKUSHIMA UTANARI
IPC: H04J14/06
Filed: 1989-07-28
Abstract: PURPOSE:To prevent an auxiliary signal from being restricted by the code form of a main signal, and to make a special filter unnecessary at a receiving side, by amplitude-modulating the auxiliary signal having frequency spectrum outside a low frequency transmission band, and superposing it on the main signal, and at the receiving side, dividing the output of the peak value detection circuit of an automatic gain control circuit, and turning it into auxiliary signal output. CONSTITUTION:At a transmitting side, the auxiliary signal having a frequency component outside the low frequency transmission band is inputted, and is superposed directly on the main signal by an optical transmitter 10 so as to be the variation of the amplitude of the main signal. At the receiving side, band limit is given by an optical fiber transmission line 20, a light receiving element 31 and an equalizing amplification circuit 32 in an optical receiver 30, and especially, a spectrum below low cut-off frequency is suppressed, and the main spectrum of the auxiliary signal is suppressed as well. Then, an auxiliary spectrum superposed on each line spectrum of the main signal in the transmission band is detected by the peak value detection circuit 35, and is outputted as the auxiliary signal. Thus, the auxiliary signal can be transmitted without being restricted by the code form of the main signal and in addition, without necessitating any special filter at the receiving side.
