Title: Macro block type judging device
Inventor: KODAMA HIDEO
IPC: H04N19/85
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a judging device capable of attaining the judgement of a certain macro block type with simple circuit constitution. SOLUTION: As to pixels on the same positions in a current macro block for judging a macro block type and a reference macro block, an absolute error of luminance is found out as a DIF. The sum of DIFs in the macro block is found out as a VAR. In each pixel, the DIF is compared with a value obtained by subtracting a parameter constant ALPHA from the luminance value CMBY of a pixel in a current macro block, a number of cases that the DIF is larger is found out as HANTEI, and when the HANTEI is larger than a parameter constant BETA and the VAR is larger than a parameter constant GANNA, the macro block type is judged as an intra mode. The other case is judged as an inter mode.

Title: Mechanism for concrete cutter
Inventor: KAMIYAMA HIDEKI
IPC: E01C23/09
Filed: 1992-07-15
Abstract: PURPOSE:To improve workability by a method wherein an engine is automatically controlled through detection of a load and the number of revolutions during cutting and the cutter is automatically traveled along a reference line. CONSTITUTION:When the number of revolutions of a cutter 1 is decreased and the torque is increased at a place where concrete is thick, the change is detected by a detecting means arranged on the cutter 1 or a drive system therefor and the car speed is reduced to cause the number of revolutions and the torque to coincide with respective preset values. The number of revolutions of an engine E and a load are then detected, the number of revolutions is caused to coincide with a preset value through control of opening and closing of the throttle of the engine E by means of an electronic governor, and the cutter 1 is rotated at the constantly specified number of revolutions. A reference line drawn on a road is detected by a cut reference line detecting sensor 11 and automatic travel is performed along the reference line through control of a steering wheel 12. When the reference line has a turning radius smaller than a value at which the cutter 1 is bendable, travel is stopped or travel is effected along a circle of a minimum turning radium. This constitution prevents the damage of the cutter, enables improvement of working efficiency, and performs accurate execution of a work even by an unskilled operator.

Filed: 1980-12-29
Abstract: PURPOSE: To reduce the power of a gate circuit for a gate turn-off thyristor GTO, so that an off-circuit and an on-circuit can be controlled with the same control element at a bundle.  
     CONSTITUTION: When an on-signal is inputted to a photocoupler PC 1 , a transistor (TR) Q 1  turns on and a TRQ 2  turns off. Thus, a TRQ 3  turns on and an on-gate current flows to a GTO in the path of R 10 →Q 3 →GTO gate → cathode → ground. When the GTO turns on, the TRQ 3  turns off and the on-gate current is narrowed. When the input signal to the photocoupler is absent, the TRQ 2  turns on and the TRQ 3  turns off. When the TRQ 3  turns off, a TRQ 4  turns on and a gate current flows to a thyristor TH 1  to turn on the Th 1 , and an off-gate current is supplied to the GTO in the path of ground → cathode of GTO→ gate of GTO→ L 1 →Th 1  to turn off the GTO.

Abstract: PURPOSE:To allow silver chloride having high sterilizing power to be supported on a material to be subjected to arc spraying by a strong bonding power by an extremely simple method wherein silver is directly supported on a base material as silver chloride by compressed chlorine gas using a low temp. arc spraying apparatus. CONSTITUTION:Chlorine gas is injected to the periphery of an arc spraying gun 15 from a slit 16 and a conical reduced pressure layer is formed with the injection of chlorine gas by an arc generating part 12. Silver of the silver wire 11 melted in the arc generating part 12 is sucked in the chlorine gas stream to be cooled to temp. 1/5 - 1//20 mean melting temp. or less. In this stage, silver is finely ground into particles having a particle size of about 5 - 150mum and also chlorinated.
