Title: Hot water boiler
Inventor: ANDO HARUMI
IPC: F24H1/24
Filed: 1988-05-30
Abstract: PURPOSE:To prevent a boiler from opening due to corrosion by oppositely disposing an electric corrosion protection electrode and a sacrificial anode material in the water chamber of the glass line boiler. CONSTITUTION:A boiler 1 is formed with a cylindrical water chamber 4 between a cylindrical inner body 2 a cylindrical outer body 3, and the inner surfaces of the chamber 4 between the bodies 2 and 3 are glass lined. An electric corrosion protection electrode 7 is provided in the chamber 4 near a heater attachment port 6 at the lower part of the boiler, and a sacrificial anode material 8 is disposed oppositely to the electrode 7. Thus, even if the glass lining is damaged, a natural corrosion protection current flows corresponding to a defective area by the material 8 to corrosion protect the defective part. Accordingly, corrosion protective characteristic can be maintained.

Title: Method of forming fine resist pattern
Inventor: KAWAZU TAKAHARU
IPC: G03F7/039
Filed: 1982-07-30
Abstract: PURPOSE:To improve resolution significantly in ion beam lithography, by a method wherein when fine resist pattern is formed to manufacture IC, prescribed pattern is drawn by irradiation of ion beam and then Deep-UV ray is irradiated collectively. CONSTITUTION:A resist of poly methyl methacrylate or the like is applied onto quartz substrate by rotation coating method and heated at 170 deg.C for 30min. Prescribed pattern is drawn by irradiation of ion beam and then Deep-UV rays radiate collectively. In this constitution, irradiated part by the ion beam obstructs a light whereas non-irradiated part is converted into lower molecule by irradiation of Deep-UV ray so as to allow development by methyl isobutyl ketone. Since the denatured layer is a mask in close contact, pattern precision of the poly methyl methacrylate becomes high.

IPC: G06T5/00
Filed: 1992-05-25
Abstract: PURPOSE:To reduce noises of masked data by referring to and storing plural data, which are similar to respective image data stored in a 1st frame memory in a 2nd frame memory, as process image data. CONSTITUTION:A 1st reference pattern storage means 4 stores a 1st reference pattern group as reference for actually judging non-masked data and a 2nd reference pattern storage means 5 stores a 2nd reference pattern group for judging real mask data in the form of specific data patterns respectively. An object pattern read out of a holding means 3 is sent to 1st and 2nd deciding means 6 and 7 and compared with 1st and 2nd reference patterns in order. The 1st deciding means 6 decides that mask data included in the object pattern is not real mask data, but non-mask data when the coincidence between the object pattern and 1st reference pattern is detected and stores the result in a corrected image data storage means 8 as corrected image data.

Title: Button-type air cell
Inventor: MORITA KOREYOSHI
IPC: H01M4/86
Filed: 1983-07-19
Abstract: PURPOSE:To minimize the variation of the internal resistance of a button-type air cell by favorably sticking together a microporous resin film used as a separator and an air electrode. CONSTITUTION:An inhomogeneous adhesive layer is formed on one surface of a separator 6 consisting of a microporous polyethylene or polypropylene. It is formed by using a pressure-sensitive adhesive having permanent tackiness such as a butyl rubber, an acrylic ester, a polybutene or a polyamide system compound. After such an adhesive is dissolved in a solvent such as toluene, the solution is sprayed on one surface of the separator 6 to form an inhomogeneous layer. Next, an air electrode 5 is stuck to the separator 6 by pressure with the adhesive layer interposed. After that the thus obtained body and a water repellent film 4 are punched into the same diameter, and the film 4 is placed on the film 6 installed in a positive case 1. By thus unifying the separator 6 and the air electrode 5 consisting of a catalyst layer by pressure by interposing an inhomogeneous pressure-sensitive adhesive layer, the internal resistance of the battery can be remarkably stabilized without causing almost no blockage of the microporous resin film.

Abstract: PURPOSE:To prevent concentration irregularity by correcting an image printing data with gamma based on gamma correcting data for odd line when an odd line is to be printed and correcting the image printing data with gamma based on gamma correcting data for even line when an even line is to be printed. CONSTITUTION:Each of colors Y, M, and C has gamma correction curves of odd line and even line, respectively, which are changed over for image printing.
