IPC: H01M50/423
Filed: 1985-03-19
Abstract: PURPOSE:To improve the electrolytic liquid holding capacity and the resistance against alkali and acid at high temperatures by controlling the ratio of polyamide resin (CONH/CH2) which forms polyamide fiber within a certain range. CONSTITUTION:The ratio CONH/CH2 of polyamide resin is controlled within 1/9-1/12. There are nylon 1010, nylon 11, nylon 12 and nylon 13, etc. as polyamide fiber of CONH/CH2 ratio within 1/9-1/12. Use of a polyamide resin of CONH/CH2 ratio higher than 1/9 results in a separator with inferior resistance against alkali and acid, while use of a polyamide resin of CONH/CH2 ratio lower than 1/12 results in a separator of lower electrolytic liquid holding capability, being unable to obtain the necessary hydrophilic property.

Title: Lighting system
Inventor: HONDA HISASHI
IPC: B01J21/06
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To restrain emission efficiency from being lowered and facilitate maintenance. SOLUTION: A translucent cover 9 covering a light source 11 which emits at least visible light rays and the light rays in a wavelength area of 300nm to 400nm. A light catalysis film is formed on at least one of the inner and outer faces of the translucent cover 9. The light catalysis film has the main component of titanium (TiO2 ) in which the peak wavelength of the transmission rate of visible light rays is almost equal to that of the light source 11. Oxidation and decomposition of a substance is accelerated with the light catalysis film by means of the infrared rays emitted from the light source 11, and adhering of dirt to the translucent cover 9 is prevented.  Even if the film thickness of the light catalysis film is made thicker to improve the light catalysis action, the peak wavelength of the visible light rays emitted from the light source 11 efficiently transmits the light catalysis film and restrains the illumination efficiency from being lowered.

Filed: 1991-02-28
Abstract: PURPOSE:To achieve uniform electron beam passing holes and improvement of accuracy by applying ultrasonic vibration to a coated etching resistant agent so as to eliminate bubbles existing in an interface between shadow mask material and the etching resistant agent. CONSTITUTION:One surface of a plate-like shadow mask material 13 is covered with a corrosion preventive film 17, and then, small holes are formed by etching the other surface having a small hole forming resist 16b. The resist 16b is peeled and removed. An etching resistant agent 18 is filled in and applied to the small holes, and is deposited on the surface where the resist is removed. Ultrasonic vibration is applied to the etching resistant agent so that bubbles contained in the etching resistant agent may be eliminated. Large recessed holes 9 communicated with the small holes 10 are formed by etching the other surface with a large hole forming resist 16a formed thereon. Consequently, the shadow mask material is completely covered with the etching resistant agent so that etching liquid is prevented from intruding into the shadow mask material, thus achieving a high quality.
