Patent JP-S61243657-A (JP)
Title: Manufacture of sintered cathode plate
Inventor: SHIMOKAWA TOMOHIRO
IPC: H01M4/28
Filed: 1985-04-19
Abstract: PURPOSE:To simplify the manufacturing process of plate and cell while to shorten the time by repeating the active material immersing operation several times where porous metal substrate is immersed with cadmium slat solution then cadmium hydroxide is deposited from the salt solution thereafter heating under the air to transform cadmium hydroxide into cadmium oxide. CONSTITUTION:A porous metal substrate is immersed with cadmium salt solution then cadmium hydroxide is deposited thereafter heated to 270-350 deg.C under the air to transform cadmium hydroxide into cadmium oxide. Such active material immersing operation is repeated several times. The final active material or Cd(OH)2 in the immersing operation is easily transformed into CdO to cause considerable variation of volume, but since heating is performed in short time, the heating temperature higher than 270 deg.C is preferable while since nickel in sintered nickel substrate will start to be oxidized at the temperature of 350 deg.C, the heating temperature in the range of 270-250 deg.C is preferable.

Title: Noise suppressing method for image pickup device
Inventor: KOMURO SETSU
IPC: H04N5/372
Filed: 1989-04-03
Abstract: PURPOSE:To improve an S/N and to suppress a low noise level by dividing a gamma correction part into two parts, providing the first and second gamma correction parts in the front and back stages of a signal processing circuit, and making a total gamma correction value same as the gamma value of the gamma correction part. CONSTITUTION:A gamma correction value (gamma1) of a first gamma correction part 7 is made small and the correction quantity of a hierarchical characteristic is enlarged to an input signal. Accordingly, since the S/N of a CCD camera is almost determined by the first gamma correction part 7 which is the amplifier circuit of the first step, the S/N is improved rather than a normal circuit. However, since gamma correction to the input signal is defined as over correction in the first gamma correction part 7, a video signal obtained in a signal processing circuit 3 is inputted to a second gamma correction part 8 and the gamma correction of the above mentioned over correction part is reversely executed to the video signal. At such a time, the gain of the signal in the area of a small amplitude is compressed and noise which is generated in the following circuit after the first gamma correction part 7 in the first step circuit, is suppressed.

CONSTITUTION:A device is equipped with a main throttle sensor 1 and a sub- throttle sensor 2, and with an ECU 3 which is put as a control section, side by side with the output stages of both of the throttle sensors. Engine revolution signals, the output voltage MV of the main throttle sensor 1 and the output voltage SV of the sub-throttle sensor 2 are inputted by a CPU within the ECU 3 so that a common difference T is computed based on a common difference computing reference which is stored in an internal memory in advance in response to information on the aforesaid engine revolution. In the second place, it is judged whether or not an unequality of ¦MV-SV¦>T is satisfied. If ¦MV-SV¦>T is satisfied, the output of the throttle sensor is judged to be abnormal, so that the detected abnormal output signal of the throttle sensor is thereby outputted.
