Title: Memory optimizing processing method and circuit device for cvbs signal
Inventor: HIRTZ GANGOLF DR ING
IPC: H04N11/16
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To provide a memory optimizing processing and circuit device for a CVBS signal through the memory control for processing in the case of re- configuration of complete vertical resolution and suppression of crosstalk in the PALplus system. SOLUTION: In order to improve image quality further, an image is displayed in a frame frequency of 100Hz. Thus, it is required to convert an image in 50Hz by interlace scanning into a frame frequency of 100Hz. In conventional technology methods, since the processing above is executed separately, lots of memory spaces are required. In this method, fields A, B are stored in different memory areas and lines with consecutive fields A, B are not stored in consecutive address areas or only part is stored in the continuous address areas according to the memory control, then the PALplus demodulation and 100Hz conversion executed simultaneously are executed by two memory modules. As a result, a demodulator for 100Hz reproduction is realized at a low cost.

Title: High-speed pulse light sensor
Inventor: NATSUME YOSHIO
IPC: G01J1/04
Filed: 1979-09-06
Abstract: PURPOSE: To prevent reflection in the connection part by matching input and output impedance in the transmission line on the signal generating/sensing side and arranging a constitution so that both inner and outer conductors may be connected in a smooth shape.  
     CONSTITUTION: If super high-speed pulse light is radiated into photoelectron emission cathode 6, super high-speed electric pulse is generated. Electric pulse is transmitted to coaxial transmission line for characteristic impedance 2R consisting of outer conductor 10 and inner conductor 11 and resistor 9 for resistance 2R through transmission line for the same characteristic impedance R composed of by-pass 2 and support rod 4 as well as of metal container 8 and support rod 4. Consequently input impedance R of this parallel circuit becomes R. In addition, smooth-shaped inner and outer conductor, i.e. columnar support rod 4 tapering in diameter near the support element 9 is finaly connected in such manner that it may match the orifice of support element 9. For this reason, reflection does not occur at the connection point. Under this constitution, it is possible to prevent reflection of electric pulse in the connection part.

Title: Data storing device
Inventor: HIROTA TERUTO
IPC: G11B20/10
Filed: 1994-05-27
Abstract: PURPOSE:To reduce the seeking operation of a storing means for data stored in a storing means as compared with the prior art by arranging data in a recording means so that the content of each data continuously obtained from a reproducing output terminal can become continuous. CONSTITUTION:When the block position of a video tape comes to the last position 11, the video tape is once rewound at a high speed and, in the second cycle, the above-mentioned operations are repeated after the video data '0' at a block position '0' is read at time t12. As a result, video data taken at different time are reproduced from each output 1-4 and supplied to each terminal. Therefore, an auxiliary storage device 15 can read or write data by performing sequential access only without performing random access except video tape rewinding time.
