Title: Transmission system for color picture signal
Inventor: YUYAMA ICHIRO
IPC: H04N11/24
Filed: 1985-05-22
Abstract: PURPOSE:To obtain a transmission system which simplifies processing circuits in transmission and reception systems by interchanging line sequences of two color signals for every frame and subjecting each of two color signals to the same preprocessing, interpolating filter processing, and subsampling processing as a luminance signal. CONSTITUTION:In the reception part side, sampling points thinned by a subsampler 5 are interpolated by a three-dimensional interpolating filter 7 and are demodulated by a TCI decoder 3. Two color signals C1 and C2 are interpolated by switching original signals and output signals of a vertical filter 20 by a switch S3. A color line sequence discriminating signal CP separated from a transmission signal is restored to a frame pulse FP by a shaping circuit 22 and is led to an exclusive OR circuit 23 together with a line pulse LP generated from a horizontal synchronizing signal HD. The switch S3 is controlled by the output of the exclusive OR circuit 23, namely, the line pulse LP inverted for every one frame, and a TCI signal where two color signals C1 and C2 are selected alternately in beginnings of individual frames is restored to a normal TCI signal.

Title: X-ray image pickup device
Inventor: SHINOHARA TAKESHI
IPC: H05G1/60
Filed: 1983-06-16
Abstract: PURPOSE:To prevent a required image from being lost by opening fully the aperture stop or inhibiting image-pickup when a radioscopic time is a prescribed time or below. CONSTITUTION:A radioscopy selection start signal 21 is generated from a radioscopy selecting switch, and a high level signal 23 is inputted to an AND gate 25 by a timer means 22 until a prescribed time T. Further, a fully opening command signal 26 of aperture stop is outputted from the AND gate 25 until the time reaches the prescribed time T. Since the aperture stop is opened fully when the radioscopic time is short in this way, the loss of a required image due to over-stopping of the aperture is avoided. Moreover, the similar effect is attained even by outputting a command signal inhibiting the X-ray pickup until reaching the prescribed time T in place of the fully opening command signal.

Abstract: PURPOSE:To obtain the magnetic material, the direction of easy magnetization of which can be changed to the direction of film surface and the direction vertical to the film surface by a method wherein the thin film of a ferromagnetic material, having the direction of easy magnetization in the direction of film surface, and a thin film of superconductive material are laminated alternately. CONSTITUTION:A superconductive YBa2Cu3Ox thin film 1 and a CoCr thin film 2, having the direction of easy magnetization in the direction vertical to the film surface, are laminated in the thickness of 1 mum for each film. The temperature characteristics of this material is as shown in the diagram (b). To be more precise, when temperature goes down from the room temperature, Hk gradually increases in the state of a positive value in the neighborhood of the superconductive critical temperature of -170 deg.C. Accordingly, the direction of easy magnetization is in the direction vertical to the film surface in the above-mentioned temperature range. When the temperature drops further exceeding -170 deg.C, the Hk is reduced suddenly, and it becomes a negative value passing zero. Therefore, the direction of easy magnetization is brought in the direction of film surface in the above-mentioned temperature range.
