Title: Process system for color video signal
Inventor: USHIO FUSAO
IPC: G11B5/027
Filed: 1978-06-16
Abstract: PURPOSE:To reduce substantially the distortion of the color signal occurring under the process in which the color signal containing the burst is added by the luminance signal and such color video signal undergoes the recording/reproducing, modulation/ demodulation and transmission. CONSTITUTION:The test signal which is generally used to measure DG and DP distortion is supplied to input terminal A as shown by (b). Pulse generation circuit 2 generates pulse signal (c) featuring the fixed level of, for example, the width of the back porch via the synchronous signal isolated at synchronous isolation circuit 1. The input signal and the pulse signal are added (d) together at adder circuit 3. At this moment, the back porch is shifted to the specified level of the video signal from the original position, i.e., from 50IRE. Then the signal given from circuit 3 is modulated at FM modulator circuit 4 and then led to the recording unit of the recording/reproducing device for the video signal. The same operation is given also to the reproduction side.

Title: Drip detector
Inventor: SAKAI HIROSHI
IPC: A61M5/00
Filed: 1990-03-26
Abstract: PURPOSE:To obtain a thin lightweight drip detector supplying parallel light uniform in quantity by mounting a strip-like parallel light-emitting means having a light emitting port emitting strip-like parallel light in a vertical direction and a sensor means on a light receiving side equipped with an image sensor receiving the strip-like parallel light. CONSTITUTION:An LED 2a for a sensor light source, an optical fiber bundle 3, an image sensor 5 and a drip detecting control part 6 are built in a case 1 and the LED 2a is connected to the optical fiber bundle 3 through a coupler 2. The light emitted from the LED 2a passes through the optical fiber bundle 3 through the coupler 2 to be emitted from the end surface thereof in a shape almost near to parallel light to irradiate a drip cylinder 4. The data from the image sensor 5 is taken in the drip detecting control part 6 and it is judged whether a waterdrip is passing through the drip cylinder on the basis of the data. The end surface of the optical fiber bundle 3 on a light receiving side may be flat but, since the light from the LED 2a is radial light, said end surface is formed into a recessed surface so as to equalize the distance between the surface of the LED 2a and the end surface 3a of the optical fiber bundle 3.

Abstract: PURPOSE:To accelerate a processing by utilizing the middle result of the preceding processing at the time of the picture element processing after the second processing while utilizing the high possibility for the part of an object being displayed at the adjacent picture element to be adjacent as well even at a position in an actual three-dimensional space. CONSTITUTION:The free curved surface of a level (i) is taken out from a memory part 11 by an including polygon calculation part 12, and an including polygon is calculated from control point position information and stored into the memory part 11. Since a vessel surface is positioned on the inside of the including polygon at the control point of 4X4, this polygon is defined as the including polygon of the free curved surface. Next, when there is no look cross with the including polygon, a cross decision part 13 stops the processing and when there is the cross, an end condition decision part 14 decides that the flatness is less than a designated value or the size of the including polygon is less than the designated value, and calculates the intersection at a polygon intersection calculation part 15. When the end condition is not reached yet, a free curved surface division part 16 divides the free curved surface into 2X2 pieces and the control point position information of the respective obtained partial curved surfaces is stored as the level [(i)+1]. After the second processing, the cross decision part 13 takes out the including polygon information at the n-th level and calculates the intersection by recurrently using a processing A as described.
