Title: Clamping circuit for television signal
Inventor: MAEDA MIKIO
IPC: H04N5/18
Filed: 1986-04-21
Abstract: PURPOSE:To clamp the TV signals with no deterioration caused to the video signals having large negative potentials by forming a switching element that is energized by a clamp pulse with the series connection of plural MOS field effect transistors. CONSTITUTION:The 1st and 2nd FET 12 and 13 are connected in series and the drain of the FET 13 is defined as a clamp potential 14 that can be set at an optional level. Here the drain potential of the FET 12 is referred to as VD together with source potentials of both FET 12 and 13 as VS and the currents conducted through both FET as IS respectively. Therefore the current ID is equal among these FET and the source-drain resistance of the FET 13 is kept at a high level. As a result, the levels of video signals are raised up. Thus it is possible to obtain such a switch that has no deterioration of its voltage holding characteristics even to the video signal which has a large negative potential while a clamping circuit is kept OFF.

Title: Method and apparatus for surface grinding
Inventor: MITSUI MIKIYUKI
IPC: B24B7/10
Filed: 1979-07-16
Abstract: PURPOSE: To prevent the production of a ground pattern on a ground surface by changing a table movement cycle at random in order to shift an uneven phase due to the vibration of a constant cycle.  
     CONSTITUTION: The table 2 is coupled with a driving mechanism 19 (hydraulic) so as to be able to reciprocate in the direction parallel to the rotating surface of a grinding wheel 1. Random delay means 10 and 11 are connected to the driving mechanism 19 to input a signal to it at a random cycle in order to change over the operation direction of the driving mechanism 19 so that the table 2 is reciprocated at the random cycle, and the table 2 and the grinding wheel 1 are moved relatively to each other  in the direction perpendicular to the reciprocating movement of the table 2 and in the direction of the infeed of a workpiece 3 respectively to grind it. Thus machining permits the uneven phase produced on the ground surface to be randomly shifted every lateral motion of the table 2, so that the production of such ground patterns as stripes and oblique cross-stripes crossing the grinding direction can be prevented.

Filed: 1987-04-15
Abstract: PURPOSE:To perform accurate pattern recognition following up the deterioration of a light source and variation in the color tone of the light source by arranging a photodetector nearby a body to be measured and performing feedback control over a lighting device according to the detection signal of the photodetector. CONSTITUTION:An image pickup device 3 and a lighting device 6 are arranged on an XY table 1 corresponding to the body 2 to be measured. While the body 2 to be measured is irradiated by the device 6, its pattern is picked up by the device 3 and recognized. At this time, a photodetector 7 arranged nearby the body 2 to be measured detects the quantity of light and color tone at the time of image pickup operation. The detection signal is fed back to the device 4 to correct the quantity of light and color toner following up their variations, thereby holding the conditions of pattern image pickup operation constant. Consequently, even if the quantity of illumination light and color toner vary owing to the secular change of, for example, the device 6, that is corrected automatically by the feedback control to perform the pattern recognition properly.
