Title: Power amplifying circuit
Inventor: NISHIMURA MASARU
IPC: H03F3/20
Filed: 1980-04-18
Abstract: PURPOSE:To reduce unnecessary loss of the circuit and to improve the overall efficiency, by adjusting the power supply voltage with required minimum conforming with the output of the amplifier and supplying it to the amplifier. CONSTITUTION:If the output voltage of the voltage amplifier 1 exceeds almost the same voltage as each output voltage of the pulse width modulation power supply terminal 11 or 12 obtained at both ends of a resistor 34, a transistor TR35 or 36 is conductive and TR30 or 31 is switched on by giving a bias to a resistor 41 or 42. Diodes 13 and 14 inserted between the output terminals 11 and 12 of the pulse width modulation circuit and each collector of TR5 or 6 in emitter follower connection prevent reverse flow from the power supply terminal 2 or 3 to the pulse width modulation circuit when TR30 or 31 is conductive.

Title: Noise reduction circuit
Inventor: MORI TAKAYUKI
IPC: H04N9/64
Filed: 1989-03-06
Abstract: PURPOSE:To form a color noise reduction circuit, for which there is no color blurring, by providing a feedback coefficient control circuit, detecting the contour component of a color carrier, reducing the feedback coefficient of a cyclic filter or making the feedback coefficient be zero when there is the contour component and reproducing the correct contour of the color carrier. CONSTITUTION:Since a signal, for which the contour and noise are reduced, can be obtained when the signal is passed through the cyclic filter, the contour can be detected by subtracting the output signal of an adder 3 from an input signal. This subtraction is executed by a subtracter 4 and the output of the subtracter is inputted to a coefficient control circuit 8. In the coefficient control circuit 8, there is a clip circuit to clip the input signal by a prescribed value and the component of the noise included in a contour component is removed. Then, the input signal is outputted as a control signal. The control signal executes so control that the a coefficient K of a variable coefficient device 10 can be reduced and a coefficient (1-K) of a variable coefficient device 9 can be enlarged. Thus, when the coefficient is controlled adaptively with the contour, the omission or tailing of the contour component is decreased.

Title: Image pickup device
Inventor: SEKIYA TSUNEO
IPC: H04N5/208
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To execute contour correction in a uniform level from a white level to a black level even when gamma correction is executed. SOLUTION: A first contour signal Pg to show its contour is formed from an image pickup signal Sb, and after superimposing this first contour signal upon the image pickup signal, the gamma correction is executed by a gamma correction means 52, thereafter, a second contour signal Pk related to the first contour signal is superimposed again upon the gamma-corrected image pickup signal. The contour correction level of a white level side by inverse gamma correction is made proper by adding the second contour signal, and besides, the overcorrection of the contour correction level of a black level side is corrected by the compression of the black level side. Thus, the image pickup signal in which uniform contour emphasis was executed extending over a whole area from the white level to the black level can be obtained.

Abstract: PROBLEM TO BE SOLVED: To obtain a rail, in which a railhead is hardened to a large depth and wear resistance is improved, by hot-rolling a carbon steel or low alloy steel of specific C content into a rail shape and subjecting this rail to heating under specific conditions and to controlled cooling. SOLUTION: After the completion of hot rolling of a carbon steel or low alloy steel of 0.60-0.85% C content into a rail shape or reheating up to a temp. not lower than the Ac1 point, the surface of a railhead is cooled from a temp. not lower than the Ar1 point at (1 to 10) deg.C/sec cooling rate until the pearlitic transformation is started in the region 11 between the surface of the vertex and side part of the railhead and a position at a depth of <=5mm from the surface.  Subsequently, the surface of the railhead is cooled at (2 to 20) deg.C/sec cooling rate until the pearlitic transformation is finished in the region 12 between the surface and a position at a depth of >=20mm from the surface, or, rapid cooling after the pearlitic transformation in surface layer part is finished is stopped at about 400-600 deg.C, and the rail is held at this temp. until the pearlitic transformation is finished. By this method, the difference between the hardness at the railhead vertex and the hardness at a position at a depth of 20mm from the railhead surface can be regulated to <=about Hv20, and a rail minimal in dispersion of hardness in a longitudinal direction can be obtained.
