At the time of a nonstandard signal, the switch 135 falls on a (b) side, the part on a right side from sample rate converters 131-133 is operated by a system clock in synchronization with the horizontal synchronization signal. The output of the converter 131 is inputted to an adder 208, the adder 208 calculates the sum at the section of one line, and outputs an interpolating signal for a moving picture. Further, the output of the converter 131 is delayed by 263 lines by a field memory 211, and becomes the interpolating signal for a still picture. Consequently, at the time of the input of the nonstandard signal, the picture is not deviated.

IPC: H04N5/232
Filed: 1986-10-15
Abstract: PURPOSE:To detect a focusing position in a short time by selecting a horizontal scan line whose high frequency component of a video signal is maximum among plural scan lines corresponding to the video signal and finding the position of a TV camera. CONSTITUTION:A differentiation circuit 9 differentiates the video signal and its maximum amplitude within horizontal scan time is detected in an amplitude detecting circuit 10, whereby the signal is stored in a storage circuit 11 during a horizontal retrace. A motor control circuit 12 detects the position of the TV camera when the horizontal scan line scans from a position detecting circuit 14, and successively stores in the storage circuit 11. A control circuit 8 finds the maximum value among amplitude data stored in the storage circuit 11, detects the horizontal scan line whose maximum value has been obtained, and transmits position data of the TV camera 6 whose horizontal scan line is obtained to the motor control circuit 12 as a focusing position data. Thus, focus position information which is the largest and which is equal to the number of horizontal scan lines can be obtained in one screen, whereby focusing position detecting time can be shortened.

Title: Direct-injection type diesel engine with spark assist
Inventor: KUDAMATSU TAKAO
IPC: F02B3/02
Filed: 1985-10-30
Abstract: PURPOSE:To prevent a misfire at the time of low load from occurring, by forming a bottom surface of a direct combustion chamber so as to be shallowed in an angular range inclusive of the position of a spark plug. CONSTITUTION:A direct combustion chamber 12 is formed into a cylindrical form to be opened at an upper end, and a bottom surface in an angular range inclusive of the position of a spark plug 20 is made to be shallower than a bottom surface 24 in any other angular range. In consequence, even if the fuel sprayed toward the spark plug 20 is little, an air-fuel mixture in and around the spark plug 20 comes to richness, whereby the spark plug 20 produces a spark in a part of the rich mixture. Therefore, even in a period when an injection quantity of fuel out of a fuel injection nozzle 14 is little as in time of low load, ignition by the spark plug 20 is surely carried out, so that a misfire is avoidable.
