Title: Method for estimating welding heat input to weld zone of metallic pipe
Inventor: UMEMOTO TADAHIRO
IPC: G01N25/16
Filed: 1989-05-30
Abstract: PURPOSE:To conveniently estimate the place having the possibility of generating defects with high workability, without damaging the wall of a penetrating pipe by measuring the shape of the inner surface of the pipe and comparing the deformation close to the root of the weld zone with the reference deformation pattern. CONSTITUTION:A tensile residual stress is generated in the penetrating pipe 3 and stub tube 4 close to the weld zone 5 by the thermal contraction caused when the molten metal is solidified. The sensitized region as one of the important factors generating defects is formed when the material is heated to high temp. by the welding heat input and then annealed. When a restricting part of high mechanical strength is present on the pipe 3, the shape of the inner surface of the pipe 3 is affected by the magnitude of the welding heat input. Accordingly, the shape of the inner surface of the pipe 3 close to the weld zone 5 is measured to obtain the deformation, and the result is compared with the reference deformation pattern. Namely, the welding heat input is high when the deforming component toward the center of the pipe 3 is large, and the welding heat input is low when the component is small. The sensitized region is estimated in this way.

Title: Zinc-halogen secondary battery
Inventor: OCHIAI TOSHIHIKO
IPC: H01M12/08
Filed: 1982-08-09
Abstract: PURPOSE:To obtain a zinc-halogen secondary battery in which the deposition of dendrites is effectively suppressed by adding a specific amount of potassium chloride or ammonium chloride to electrolyte consisting of zinc chloride or zinc bromide solution. CONSTITUTION:In a zinc-halogen secondary battery of the electrolyte-circulating type, 2-3mol/l of potassium chloride or 2-4mol/l of ammonium chloride is added to electrolyte consisting of 0.8-3.0mol/l zinc chloride or zinc bromide solution. By the use of such electrolyte, the deposition of dendrites is suppressed, and a homogeneous zinc electrodeposition without any dendrites is obtained over the entire surface of the electrode during charge and discharge. Owing to the use of such electrolyte, a zinc-halogen battery with a long life can be obtained by preventing any decrease in the energy efficiency of the battery.

Title: Method for controlling color reproduction
Inventor: WAKI RIGIO
IPC: G03G15/01
Filed: 1992-04-14
Abstract: PURPOSE:To provide a method by which anyone can easily and surely control color reproduction in color photography or color copying, etc. CONSTITUTION:A color chart plate where many various color chips are arranged/applying the principle of opposite color characteristic, is used. In figure, N shows the part of neutral gray, YMC and BGR show the filter colors(or adjusting color) of yellow, magenta and cyan, and blue, green and red respectively any of which should be used for correction. A numeral expresses the density of a filter. Namely, the color obtained by converting color balance in an opposite direction to the designated filter color with reference to the neutral gray is arranged in each part. For example, the part of 10Y shown by 2 is adjusted to be the color obtained by adding the 10B filter(or subtracting the 10Y filter). In the case that the color quality of a light source is correct, the N in the chart looks gray. In the case that it is not correct, the N causes color fog and any other step area becomes neutral gray, so that the light source is corrected by setting the filter having density and color shown at that position as a correction filter or corrected by that color.

Abstract: PURPOSE:To improve stability at the time of low speeds while a sufficient compression ratio being accomplished at the time of low revolving speeds by installing a deflection setting equipment at the midway on the tension side of the timing belt or chain of a synchronized transmitting mechanism, which moves from a driven wheel to a driving wheel. CONSTITUTION:An auto-tensioner 14 absorbing the deflection of a belt 4 with a constant tension given is installed at the midway on the feeding side 13 of the timing belt 4 in a synchronized transmission wherein a driving wheel 9 is connected with a driven wheel 10 by the timing belt 4 with a suction/exhaust cam 12 installed on the shaft 11 of the driven wheel 10. And a deflection setting equipment 16 is installed at the midway on the tension side 15 of the timing belt 14. The movement to the arrow head direction of the roller 17 at the tip end of the deflection setting equipment 16 deflects the tension side 15 of the belt 4 as shown by dotted lines, thereby advancing the timing for a work by the amount of the deflection thereof. This constitution thereby enables a sufficient compression ratio to be accomplished even at the time of low revolving speeds.

IPC: H01M50/77
Filed: 1988-06-03
Abstract: PURPOSE:To prevent electrolyte from stagnating by furnishing an inlet header with one or more through holes to spray the electrolyte to such parts as easy to produce stagnation, and providing an outlet header with one or more through holes which can feed the electrolyte in the same parts to a feed-in pipeline. CONSTITUTION:An inlet header 8 is furnished with one or more through holes 8a arranged so as to spray the electrolyte after passing through an electrolyte returning line 5 to such parts as easy to generate stagnation in an electrolyte tank 3. An outlet header 9 is provided with one or more through holes 9a arranged so as to feed the electrolyte in these parts of the electrolyte tank 3 into an electrolyte feed-in line 4. This enables agitation of the liquid in the tank 3 only with the electrolyte circulation propelling force of a circulating pump. Thereby stagnation of the electrolyte will not be generated, which does not require any wasteful electric power.

Title: Facsimile equipment
Inventor: IWAMOTO YOSHINORI
IPC: H04N1/32
Filed: 1985-06-25
Abstract: PURPOSE:To perform multiple address transmission with simple constitution without providing a multiple address device and a large-capacity storage device by driving a readout scanning part and making a readout scan on an original every time a transmission party specified during transmission is called. CONSTITUTION:When a communication switch is pressed, the readout scanning part 3 is set at a readout scan start position on an original platen 2 and an address number is read out of an area specified with an abbreviation key of a storage part 9. Then it is decided whether the readout result is correct or not and when the result is correct, a network control circuit 15 is driven to send out a call signal, calling the opposite terminal. When the opposite terminal answers to the call, the readout scanning part 3 begins to make a readout scan on the original and sends out obtained image information to a circuit 5. A control circuit 12 monitors the end of the transmitting operation during the transmitting operation. Consequently, the readout scanning part 3 makes a scan every for every transmission terminal and transmits the image information, thereby eliminating the need to store the image information.

Title: Reading method capable of reading bar code in standstill state
Inventor: TSUCHIDA YUUKI
IPC: G06K7/10
Filed: 1982-08-11
Abstract: PURPOSE:To read a bar code in a standstill state regardless of its kind, by projecting an image of a bar code string upon a one-dimensional image sensor and inputting it as a bit pattern. CONSTITUTION:The bar code string BC is irradiated with light from a light emitting device LA and its image is projected upon the image sensor IS through an optical lens LE. Then, a CPU actuates a driving circuit CNT, which controls the image sensor IS to obtain a video output VO. This video output VO is amplified by an amplifier AMP and then compared by a comparator CMP with a specific threshold level SH to be converted into a digital signal DS. Said programmable controller CPU recognizes a still pattern on the basis of the digital signal DS. Therefore, a stable read of the still pattern is made regardless of the kind of the bar code without the need for a timing component.
