Abstract: PURPOSE:To cut off crosstalk and noise between circuit conductors and to radiate heat positively, by covering the surface of each circuit conductor with shielding films, adhering heat radiating films on said shielding films, and studding an insulating film with a plurality of heat radiating windows arranged along the length of the heat radiating films. CONSTITUTION:Circuit conductors 11 and 12 are formed on one or both surfaces of a board 10 of a printed circuit board 22. The surface of each circuit conductor 11 and 12 is covered by shielding films 13 and 14 and heat radiating films 17 and 18 are adhered on said shielding films 13 and 14. An insulating film 19 is formed on the circuit conductors 11 and 12 and studded with a plurality of heat radiating windows 20 and 21 arranged along the length of the heat radiating films 17 and 18. This prevents crosstalk and noise between the circuit conductors 11 and 12 and effectively avoids the influence of external noise. The heat radiation during the operation of the circuit conductors 11 and 12 of the printed circuit board 22 prevents malfunction caused by heat and improves the heat resistance of the circuit conductors 11 and 12 and the accuracy and durability of the printed circuit board 22.

IPC: H01M10/05
Filed: 1988-02-10
Abstract: PURPOSE:To increase the capacity of a battery and to improve self-discharge performance by forming a negative electrode by supporting an active material on a support comprising a specific carbon and an alloy with the active material. CONSTITUTION:Lithium or an alkali metal mainly comprising lithium is used as a negative active material. A support is formed with a mixture of carbon in which a ratio of hydrogen to carbon (H/C) is less than 0.15, the spacing (d002) in face (002) measured by X-ray wide angle diffraction method is 3.37Angstrom  or more, and the crystal lattice size (Lc) of a crystallite in C-axis is 150Angstrom and an alloy of the active material. If H/C, d002, or Lc is out of the specified value, the overvoltage of the negative electrode in charge-discharge is heightened. As a result, gas is evolved from the negative electrode. This adversely effects on the safety of a battery and charge-discharge performance is decreased. Steady high-capacity is obtained, high rate discharge is made possible, and self-discharge performance is improved.

Abstract: PURPOSE:To improve the production yield of a MOSIC, etc., having a fine structure by mounting a photofading film which has photofading property and a low photofading sensitivity against an exposure wavelength on a substrate having high reflecting power and forming a positive type photoresist film on the film. CONSTITUTION:A high reflection film 20 composed of aluminium having about 1mum in film thickness is mounted on the substrate 10. Next, the film 20 is formed by dissolving styryl pyridium having the photofading property against a wavelength of 436nm in polyvinyl alcohol and a demineralized water, and then the photofading film 26 having the photofading sensitivity of 500mj is formed on the film 20 by applying an obtd. solution on the film 20 according to a spin coating method, followed by thermally treating the obtd. film. Subsequently, the positive type photoresist film 12 having about 1mum in film thickness is formed on the film 26, followed by thermally treating the obtd. film at the temp. of 80 deg.C. Thus, the film 12 is exposed with the exposure wavelength of 436nm and the exposure of 100mj, followed by developing the film 12. As the film 26 is water-soluble, the film 26 dissolves in a developing solution during developing it, thereby being formed the pattern dimension (b) of the photoresist corresponding faithfully to a photomask dimension (a).
