Patent JP-H07211319-A (JP)
Title: Lead-acid battery
Inventor: SAWAI KEN
IPC: H01M4/62
Filed: 1994-01-24
Abstract: PURPOSE:To provide a lead-acid battery with high discharge efficiency at low temperature and long life by adding chitosan to a negative active material. CONSTITUTION:Chitosan is added independently or together with the conventional shrink-resistant agent to a negative active material as an expander in place of lignin conventionally used. The chitosan is a polysaccharide of 2- amino-2-dioxy-D-glucose, and a natural organic high polymer having a structure similar to cellulose. This material covers active sites on the electrically deposited surface of lead when a negative plate is charged to retard crystal growth, and discharge efficiency at low temperature and life are increased same as lignin conventionally used. Since chitosan is resistant to decomposition in a sulfuric acid solution compared with lignin, it stays in the negative plate to maintain the effect until the life of the negative plate finishes.

Title: Production of electric resistance welded steel pipe
Inventor: MORIBE KENJI
IPC: B21D5/12
Filed: 1989-02-01
Abstract: PURPOSE:To greatly improve the thickness distribution in edge parts and to improve dimensional accuracy by previously reducing the thickness of the part corresponding to the edge thickness increase parts by rolling down in a transverse direction, thereby offsetting the edge thickness increase. CONSTITUTION:A steel strip 1 is cut by a slitter and the end face 19 thereof is not square. The thickness in the edge parts is reduced in order to offset the edge thickness increase by bending as the fore stage for bending. The steel strip is so rolled down from a vertical direction by forming horizontal rolls H1 as to have the thickness distribution in which the end faces are thin and the thickness increase successively toward the central part. The steel strip 1 is then rolled down in the transverse direction and is formed in the edge parts by forming vertical rolls E1. The steel strip is rolled to the curvature of the value nearly the curvature of the final shape of the product by forming vertical rolls E2 as the final stage. The thickness reduction at the edges of the steel strip 1 by the H1 is offset by the thickness increase at to edges by the rolling down in the transverse direction by the E1 and E2, by which the thickness distribution of the edge parts is made uniform. The steel strip is then subjected to the bending in a breakdown stage.

Abstract: PURPOSE:To improve noise resistance even when a current to be detected is large by connecting a voltage/current converting circuit and a high frequency detecting circuit to a magnetic multivibrator circuit in the detector for the leak current of a power line. CONSTITUTION:An AC power source EO is connected to a power circuit A and the potential of the emitter line l4 of a transistor (TR)1 is held constant.

Then, a duty circuit C detects a duty ratio and outputs a corresponding signal. Then the high frequency circuit E detects a frequency when the current to be detected is large and the frequency of output pulses is high. When the current to be detected is small, the voltage/current converting circuit F detects the duty ratio of the output pulses. Therefore, the current to be detected is detected securely by the circuits E and F.

IPC: H03F1/32
Filed: 1985-02-12
Abstract: PURPOSE:To obtain easily a required output signal dynamic range and to improve the output signal distortion by eliminating a level shift found often in a conventional signal transmission circuit. CONSTITUTION:A DC level of input/output terminals 2, 3 is made equal by applying an equal current to transistors (TR) 10, 11 and no level shift is re ceived. In matching respectively TRs 8, 9, and 14, 15, and 10, 11, and resistors 6, 7 and 16, 17, a collector current identical to a collector current Ic of the TR11 is fed to the TR10 through the operation of a current mirror circuit. Thus, the collector current Ic is subjected to fluctuation of an input signal level, waveform distortion is caused between the base and emitter of the TR11, but since the same waveform distortion due to the collector current fluctuation of the TR9 is caused between the base and emitter of the TR11, the waveform distortion by the TRs 10, 11 is cancelled in the output signal at a signal output terminal 3 and an output signal without waveform distortion is obtained.

Abstract: PROBLEM TO BE SOLVED: To provide the arranging method for display for control which can speed up a data block rearranging process by processing the rearrangement of data blocks by processors in parallel. SOLUTION: A screen is divided into areas so that areas which are not adjoined among the divided areas are at a distance longer than the display range of data blocks (step 101). It is determined which of the divided areas a target symbol belongs to (step 102) and on the basis of the determination, data blocks related to the target symbol belonging to the area are rearranged so that an overlap with other display for control becomes small (steps 103 to 111). At this time, parallel rearrangement is carried out between areas which are not adjacent among the areas (steps 104 to 107 and 108 to 111). Through this parallel processes, the rearrangement can be speeded up.

IPC: H04B10/00
Filed: 1985-02-14
Abstract: PURPOSE:To attain ease of optical axis adjustment by using a detection section to detect the presence of a carrier signal from a limiter amplifier, comparing the result at a comparator, activating a drive section with its output signal and lighting a display light emitting element. CONSTITUTION:An optical modulation signal 19 incident in a photodetector 1 is converted into an electric signal by the photodetector 1 when optical axes are matched and the signal is amplified by a preamplifier section 2. The amplified signal is selected by a band pass filter 3 and amplified by an amplifier section 4 and a limiter amplifier 5. Since the output of the amplifier 5 is detected for the carrier by a detection section 7, the output of the detection section 7 goes to a high level, the level is compared with a predetermined reference level by a comparison section 8 to activate a drive section 9. Thus, a display light emitting element 10 is lighted to notice the matching of optical axes.
