Title: Negative electrode for lithium secondary battery
Inventor: HINO YOSHIHISA
IPC: H01M4/134
Filed: 1987-05-01
Abstract: PURPOSE:To increase charge-discharge performance and cycle life by using a lithium alloy negative electrode mixed with fibers of a metal which is difficult to be alloyed with lithium. CONSTITUTION:A lithium alloy negative electrode mixed with fibers of a metal which is difficult to be alloyed with lithium is used. As these fibers, stainless steel, or fibers of nickel, titanium, or steel can be used. Conversion of the negative electrode into fine particles attendant on charge-discharge cycles is retarded. Decrease in electron conductivity is therefore retarded and the cycle life can be increased.

Title: Transformer and switching regulator
Inventor: SATO YUICHI
IPC: H02M3/338
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of components of a power source unit and further prevent the destruction of a winding by forming a transformer of a core having an air gap and the winding formed around the core, and minimizing the winding density on the air gap to thereby suppress an increase in winding temperature due to a magnetic field leakage. SOLUTION: A winding 20 is made of, e.g. enameled wire, and is turned densely at end regions 22 and 24 of a first core member 12 and a second core member 14, respectively. A central region 26 between both end regions 22 and 24 includes a region around an air gap 16 and extends to a region influenced largely by a magnetic field H leaking from the air gap 16. This region largely influenced by the magnetic field H leaking from the air gap 16 is determined, considering such factors as the size of a core 10, intensity of the magnetic field H, and heat resistance. An EE core having an E-shaped cross section has its winding density on the air gap 16 set to the minimum value, the air gap 16 having the largest magnetic field leakage.  Thus, since the number of turns of the winding 20 crossing the magnetic field leakage is decreased, the amount of heat generated is small, and hence an increase in the temperature of a transformer can be suppressed.

Title: Resin composition
Inventor: FUKUNISHI YOSHIHARU
IPC: C08L29/04
Filed: 1993-05-11
Abstract: PURPOSE:To obtain a resin composition excellent in compatibility, mechanical properties and transparency by mixing a specified vinyl alcohol polymer with a polymer having carbonyl groups in the main chain. CONSTITUTION:The composition comprises a vinyl alcohol polymer (A) of a syndiotacticity of 55% or more in term of a diad and a polymer (B) having carbonyl groups in the main chain (except a poly-3-hydroxybutyrate polymer). The syndiotacticity herein mentioned is one in terms of a diad as determined by dissolving a vinyl alcohol polymer in deuterated dimethyl sulfoxide and determing it from the peak ascribable to hydroxyl group in the proton NMR measurement. When the syndiotacticity is below 55%, the compatibility of polymer A with polymer B is poor, and the composition can not exhibit the above- mentioned effects. According to the mixing ratio, this composition has a suitable water absorptivity.

Title: Developing method
Inventor: HORIE KIYOSHI
IPC: G03G13/09
Filed: 1979-08-30
Abstract: PURPOSE: To enable always stable and uniform images to be obtained without producing any toner pool by widening the spacing between a photoreceptor and a magnetic roll to the extent that the toner does not accumulate the applying the specific bias voltage to a developing sleeve.  
     CONSTITUTION: When bias voltage is applied to a developing roll 4 with an electric power source 9, the charge is injected into the toner and when said charge is of the same polarity as that of a photoreceptor 1, the development is inhibited and when of opposite polarity, the development is accelerated. In addition, the developing capacity of the photoreceptor 1 relates to the distance between the developing roll 4 and the photoreceptor 1 (DRS). Hitherto, the DRS has been set at 0.3m/m to reproduce the image of 0.2 density to the copy density of 0.4, but this DRS is made wider and that portion is compensated by the bais voltage which is of the polarity opposite from that of the electrostatic latent image and whose value is V 1 -V 2 ± 100V (V 1  is the potential of the lowest density of the original and V 2  is the potential of the nonimage portions). Thereby, no toner pools are produced even if the DRS is set at 1m/m and the good copy image may be obtained.
