IPC: H04N7/26
Filed: 1992-09-01
Abstract: PURPOSE:To obtain an input dynamic range optimum for an input video signal level. CONSTITUTION:An inputted video signal SIN is clamped by a first reference power source VREF1 at a clamping circuit 1, and it is A/D-converted in an H-bit A/D conversion part 2. The maximum signal level of the output of the conversion part is detected in a signal level detection circuit 3, and is supplied to an adder 5 via a D/A conversion part 4. The adder 5 adds the output from the D/A conversion part 4 to the first reference power source VREF1, and sets the output as a second reference power source VREF2 for the A/D conversion part 2. Those first and second reference power sources VREF1, VREF2 show a lover limit voltage and an upper limit voltage for the input dynamic range of the A/D converter, respectively, and the upper limit voltage VREF2 is changed corresponding to the input signal level, therefore, the optimum input dynamic range of the A/D converter in accordance with the input signal level can be obtained.

Title: Alkaline battery and negative electrode active material therefor
Inventor: NAKAMURA KIYONOBU
IPC: H01M4/06
Filed: 1988-09-20
Abstract: PURPOSE:To greatly suppress hydrogen gas generation and yet improve discharge performance by adding a particular amount of fluorinated alkylester to a negative electrode active material consisting of zinc alloy powder. CONSTITUTION:There are comprised zinc alloy powder, an electrolyte, and a negative electrode material 3 consisting of 100 weight parts of zinc alloy powder and 0.001-1.0 pts.wt. of fluorinated alkylester added to it. If the added amount of fluorinated alkylester is less than 0.001 pts.wt., the effect to improve corrosion resistance of zinc and prevent hydrogen generation can not be obtained. On the other hand, if the amount is more than 1.0 pts.wt., good discharge performance can not be obtained because a barrier is formed by the fluorinated alkylester to prevent the dissolving reaction of zinc, etc. Thus, hydrogen gas generation in the battery is greatly suppressed and yet the battery performance is improved even if the mercury content ratio is lowered than heretofore.

Title: Electrolytic-capacitor driving electrolyte and electrolytic capacitor using the same
Inventor: SHINPO SHIGEO
IPC: H01G9/035
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To make extensible at a high temperature the life time of an electrolytic-capacitor driving electrolyte, by adding to an organic solvent one or more kinds of solutes made of inorganic and organic acids or these salts, and by dissolving additively a cationic interfacial activator to the solvent to form the electrolyte. SOLUTION: Adding one or more kinds of solutes made of inorganic and organic acids or these salts to an organic solvent, a cationic interfacial activator is dissolved additively in the solvent to use the resultant as an electrolytic- capacitor driving electrolyte. Hereupon, the structure of the cationic interfacial activator is formed based on the equation of +N-(R1)(R2)(R3)-(CH2-O)m-H (where R1-R3 are substituents selected from among -C2H4OH, -CH2OH, -CH3, -C2H5, and -H, and R1-R3 may be selected simultaneously to be the same substituent, and further, m is an arbitrary natural number.). Still, it is not desirable that the cationic interfacial activator of -C2H4OH is added independently to the solvent of ethylene glycol, because its solubility in ethylene glycol is reduced.

Title: Field effect transistor
Inventor: HIROSE MAYUMI
IPC: H01L21/338
Filed: 1986-10-03
Abstract: PURPOSE:To suppress the demerits of an increase in a capacity and a decrease in a breakdown strength to the minimum limit by forming a drain region thickly, a source region in a low concentration thinly and an impurity concentration profile in high concentration asymmetrically. CONSTITUTION:An operating layer 12 is provided on a semiinsulating GaAs substrate 11, a gate electrode 13 is provided on the layer 12, and high concentrations of source, drain regions are formed by an ion implanting method.

Title: Method of bending work of pipe
Inventor: HATSUTORI ICHIROU
IPC: B21D9/01
Filed: 1983-12-12
Abstract: PURPOSE:To bend a pipe with high working accuracy by setting a shape memory to alloy transformation temperature, restoring to an original shape and taking out after inserting a coil spring made of shape memory alloy into a pipe and performing bending work. CONSTITUTION:A filling material 1 stores a nearly straight original shape 1-A above transformation temperature and is transformed to a coil spring-like shape 1-B by winding at room temperature. This roughly formed coil spring 1-B is inserted to come into close contact with inner face of the pipe 2 and bent. At this time, as the roughly formed coil spring has rigidity necessary for keeping the sectional form circular and yet flexible, bending of the pipe 2 is not hindered, and the pipe 2 can be bent with high accuracy. When it is heated to above transformation temperature, the roughly formed coil spring 1-B stretches almost linearly and returns to the original shape 1-A, and can be taken out from the pipe 2 easily. The filling material 1 is used again as roughly formed coil spring 1-B.

Title: Spreading device for substance to be washed
Inventor: KAJIWARA JUJI
IPC: D06F67/04
Filed: 1989-09-12
Abstract: PURPOSE:To automatically spread a substance to be washed by a method wherein either an endless belt or a partition rail is vertically moved. CONSTITUTION:When substances to be washed are charged in a chute 2, the substance to be washed is disentangled from each other by means of an up-air- injection flow generated by an air injection means 3 and dropped on a conveyor 8 for spread. Through conveyance by means of an adsorption conveying means, an upper surface is adsorbed and the substance to be washed is conveyable on endless belts 8a. A coupling means being an engaging means for the substances to be washed is coupled to a coupling means mounted on the endless belts 8a running in a direction crossing the conveying direction of the substance to be washed and in a lateral and outward and reverse directions to each other. Thereby, the substance to be washed is laterally spread by means of conveyors for spread. Since, when the substance to be washed is spread in a direction crossing a longitudinal direction, either the endless belt 8a or a partition rail 8b is vertically moved, coupling means for the substance to be washed and for a conveyor 8 is uncoupled by means of the partition rail 8b arranged in parallel to and between the conveyors 8 for spread. This constitution automatically spreads a sheetform substance to be washed.
