Patent JP-H08287916-A (JP)
Title: Lead-acid battery
Inventor: OKADA YUICHI
IPC: H01M4/14
Filed: 1995-04-14
Abstract: PURPOSE: To provide a lead-acid battery which is excellent in low temperature high efficiency discharging performance and service life performance by forming the lead acid battery by adding a cation exchange resin and lignin to a negative electrode active material. CONSTITUTION: Lignin and cation exchange resin are added to a negative electrode plate, or cation exchange resin fine powder having an average particle diameter not more than 10μm is added to the negative electrode plate instead of the lignin. The cation exchange resin is an aromatic high polymer similar to the lignin and has an action of reducing oversaturation of a Pb<2+> ion at discharging time and of restraining crystal growth by covering an active spot of an electric deposit surface of lead at charging time. Since the cation exchange resin has very large molecular weight, it is harder to be decomposed and eluted than the lignin, and can maintain an effect in the negative electrode plate up to the last period of the service life.

Filed: 1991-04-18
Abstract: PURPOSE:To prevent generation of environmental dust pollusion and obtain operational stability, by sticking and drying non-hydrated and non-cured mixed slurry of burnt gypsum and adhesive on a reinforcing core material and placing this dried gypsum layer in a molding after hydrating. CONSTITUTION:A mixture slurry of burnt gypsum powder and a synthetic resin adhesive dissolved in an organic solvent which does not cause hydration is applied on a reinforcing core plane 1 having flexibility and water-adsorptive nature like glass fiber. Next, the organic solvent is evaporated and the mixture is sticked and dried in a non-hydrated condition on the surface of the reinforcing core material 1. In this case, on evaporating of the organic solvent, it transfers to the surface at the same time to form a high dense adhesive layer. In this case, ethanol, acetone, etc., are used for organic solvents and solvent polyvinyl alcohol or the like are used for an adhesive. Next, this dried gypsum is hydrated to be softened at a construction site and applied along a molding made of wood or synthetic resin having a specified shape. After cure of gypsum, the molding is removed.

Filed: 1995-05-12
Abstract: PURPOSE: To obtain an NAND type mask ROM having gate length of half micron or less in which the ON current of memory cell transistor is increased without increasing the number of steps or masks. CONSTITUTION: Gate electrodes 6a-6e are formed through a gate oxide 5 on a P-type silicon substrate 1 partitioned through a field oxide 2 into a memory cell region 3 and a peripheral transistor region 4. Subsequently, N<-> type diffusion layers 7a-7g are, formed followed by deposition of an insulation film 8 by bias ECRCVD. Since the insulation film 8 is not deposited at the edge 12a-12h of a memory cell gate electrode, a side wall 9a, 9b is formed only in the peripheral transistor region 4 when etch back is effected on the entire surface. When an N<+> type diffusion layer 10a-10g is subsequently formed thereon, Nch single cell transistors 13a-13d and an Nch LDD transistor 11 are formed.

Filed: 1978-09-18
Abstract: PURPOSE: To obtain a portable unit which reduces power consumption and uses batteries as a power source by automatically detecting a recording start point by a mechanical constitution and then by performing switching control of a stop mode and reproduction mode on the basis of the detection output.  
     CONSTITUTION: Once tape-supply side reel frame 13 stops on detecting a recording start point, an automatic stop mechanism operates to change a tape rewind mode into a stop mode. Namely, take-up side reel frame 14 stops attending upon the stop of reel frame 13, so that detection board 132 will not be applied with rotational force any more. As a result, rest pin 133a of operation member 133 drives operation member 133 engaging with lock part 134d of automatic stopping rotation body 134. Then, support member 135 turns and the hook part at the tip of flywheel lock member 137 hooks projection part 120b of flywheel 21 to release tape take-up member 24 from an operation state through link member 138 and lock board 129. The power consumption is reduced under mechanical control like this.

Abstract: PURPOSE:To improve the operability of a display saving recovering system by saving display information not required for being always displayed at the unnecessary point of time and automatically recovering it at the necessary point of time. CONSTITUTION:Whether the system screen information is to be required or not at the current point of time is decided by a required/unrequired deciding means, and when it is necessary, 1st and 2nd picture buffers 102, 103 are synthetically displayed by a screen display control means. When it is unnecessary, only the 1st screen buffer is displayed by the screen display control means and the system screen information is temporarily saved from the display device. When the system screen information is required again, the 1st and 2nd screen buffers 102, 103 are resynthesized and displayed and the system screen information is recovered on the display device 101. Thus, the screen information requiring the display of a mouse/cursor or the like can be automatically saved or recovered as necessary.

Title: Automatic detecting device for each boundary of cuts
Inventor: IIJIMA GORO
IPC: H04N5/253
Filed: 1986-05-21
Abstract: PURPOSE:To automatically detect each boundary of cuts by dividing each frame of reproduced image signals into plural sections to obtain the picture information in the each section, and obtaining the correlation of the picture information of each section between sequential frames. CONSTITUTION:The reproduced image signals in one frame F are divided into the plural sections S11, S12, ..., S33 by an image information extracting means 3, and signal processing is applied separately to each section to obtain the picture information representing the feature of a image. Thus produced picture information is compared with the picture information in the preceeding frame by a correlation means 4 to obtain the correlation between the two frames. The output of this correlation is compared with a refrence value by a decision means 5. In case of the output is below the reference value, the frames are judged to be consecutive frames in one cut, but in case the output exceeds the reference value, the frames are judged to be the ones at the boundary, of cuts, and a detection signal is outputted.
