Title: Production of fatty oil-modified resol phenolic resin
Inventor: NEMOTO KAZUHIKO
IPC: C08G8/32
Filed: 1984-01-13
Abstract: PURPOSE:To obtain the titled resin in good yield, by reacting a fatty oil with a phenol in the presence of an acidic catalyst, reacting the product with a formaldehyde and a tert. amine and reacting the obtained product in the presence of a weakly basic catalyst. CONSTITUTION:A fatty oil such as tung oil or castor oil is reacted with a phenol (e.g., phenol or cresol) in the presence of an acidic catalyst (e.g., p-toluenesulfonic acid). To this reaction product are added a formaldehyde (e.g., paraformal dehyde) and a tert. amine (e.g., trimethylamine), and the resulting mixture is subjected to a first step reaction in which methylolation takes place preferentially. To the obtained reaction product is added a wealky basic catalyst (e.g., ammonia or diethylamine), and the mixture is subjected to a second step reaction in which condensation takes place. In this way, a fatty oil-modified cresol phenolic resin excellent in flexibility, etc., can be obtained in a high conversion.

IPC: H01M50/417
Filed: 1985-01-16
Abstract: PURPOSE:To prevent an electrolytic solution from being absorbed in impregnant material between the coupling and sealing of positive and negative electrodes and also prevent the leak of the solution at sealing by impregnating the electrolytic solution impregnant material, interposed between the negative electrode and a separator, with resin. CONSTITUTION:Impregnant material 4 is formed by dissolving sulfonated polyethylene and such in toluene and such, allowing unwoven fabric such as mercerized pulp to pass through the solution, and drying it. In addition, an alkaline battery such as a silver oxide battery is formed by interposing the impregnant material between a negative electrode 5 that is mainly made of amalgamated zinc and a separator 3 and combining it with a positive electrode 2 in which Ag2O and carbon are mixed and such. As a result, since the impregnant material 4 is impregnated with resin, the leak of the solution at sealing and the disconnection of the impregnant material 4 caused by the fact that the impregnant 4 is impregnated with an electrolytic solution between the coupling and sealing of the positive and negative electrodes can be removed and the internal resistance after aging can be improved.

Filed: 1995-01-17
Abstract: PURPOSE: To obtain an optical coupling structure with which the easy optical axis alignment in a height direction is assured and to improve the radiation characteristic of a mounted end face type optical element by specifying the structure of a mixed electrical and optical module. CONSTITUTION: High-density electric wiring is realized by using a mixed electrical and optical hybrid wiring board 10 formed by laminating and integrating polymer optical waveguides 14 on multilayered copper polyimide wiring layers 11'.

Filed: 1980-01-21
Abstract: PURPOSE: To prevent water drops from attaching to the ceiling of a microwave oven provided with multiple cooking functions by simultaneously or time-divisionally energizing the heater for generating steam and the upper heaters in the oven in the steam cooking mode.  
     CONSTITUTION: When cooking is performed by selecting the steam mode, the selection of the steam mode by a selecting switch 11 causes a power to be supplied to a heater 7 for generating steam and by said heating, steam is generated from a boiler 5 and supplied into an oven 1.

Abstract: PURPOSE:To print at a speed higher than a limited printing speed (relatively moving speed) by drawing a line by means of continuing jet-out of nozzles in response to lineality when a prescribed character or figure corresponding to each nozzle position is linear in the relatively moving direction of the nozzles. CONSTITUTION:In an image of matrix data corresponding to a character '0', left-hand numerics 1 to 7 correspond to the nozzles 1 to 7, and lower numerics 0 to 6 indicate the timing of a hourly interval corresponding to one cycle of the turn-on/off of the nozzles. They are weighted by two-digit hexadecimal numbers shown at the right, and this weight specifies the nozzles to be turned on. Judgement on whether the nozzle turned on at some timing is turned off after jet-out at the timing or kept turned on until next timing is made by ANDing a code of the timing concerned and a code of next timing. Since the code concerned is 41 and the code of next timing is 41 at a timing 2, 41 AND 41=41. Accordingly, the nozzles 1 and 7 turned on at the timing 2 are left turned on until next timing.
