A timepiece dial plate comprises an upper plate (1) provided with holes (2, 4) and positioning legs (3) projecting from its lower surface so as to position the upper plate (1) relative to a movement; and a lower plate (11) provided on its upper surface with solid indices (12) to be fitted in the holes (2) of the upper plate (1) so as to protrude from an upper surface of the upper plate (1), and provided with holes (13) through which the positioning legs (3) of the upper plate (1) are extended. The upper plate (1) and the lower plate (11) are superposed so that the solid indices (12) of the lower plate (11) are fitted in the holes (2) of the upper plate (1), respectively, and protrude from the upper surface of the upper plate (1), and the positioning legs (3) of the upper plate (1) extend through the holes (13) of the lower plate (11), respectively.
摘要:
A small scale electronic telephone exchange system of stored program control type having a plurality of trunks and a central computer has been disclosed. The trunks function to process the real time operation and, therefore, the central computer does not need to operate on a real time basis. The central computer always scans the condition of the trunks and the subscriber's telephone terminals and, upon detecting the change of said condition, it analyzes said change and performs the necessary process for said change. The present exchange system provides many new services but the cost of the system is reasonable.
摘要:
A stacked heat exchanger includes separate flow paths 54 and 55 which are formed by corrugated inner fins 52 and 53, disposed in chambers 48 and 49 of a flat tube 41, and also separate U-shaped flow paths 56 are formed at the U-turn portion 50 to make the flow of refrigerant smooth, increase the area of flow paths, and eliminate the stagnation of refrigerant at the U-turn portion 50. The separation of refrigerant into two phases of gas and liquid due to centrifugal forces at the U-turn portion 50 is limited to the inside of each divided U-shaped flow path 56, thereby the distribution of the gas and liquid phases can be decreased. Also disclosed is a method of manufacturing a stacked heat exchanger, in which the reliability of flat tube 41 is improved, and the leakage of refrigerant is prevented.

摘要:
A coating composition for use in a hydrophilic treatment comprising (A) an organic-inorganic composite reaction product prepared by a process which comprises reacting 100 parts by weight, as the solid content, of (i) a water-dispersible silica with 0.1 to 10 parts by weight of (ii) a polymerizable vinylsilane monomer containing hydrolyzable alkoxysilane group to form an aqueous polymerizable vinyl group-containing silica dispersion and then reacting the aqueous polymerizable vinyl group-containing silica dispersion with (iii) a mixture of polymerizable unsaturated monomers other than the above (ii); (B) a curing agent and (C) a hydroxyl group-containing polyester resin, the ratio of the component (A) to the component (B) being in the range of 99 to 50:1 to 50 as the solid content weight ratio, and the amount of the component (C) being in the range of 5 to 60% by weight based on the solid content in the composition comprising the component (A), (B) and (C); a hydrophilic-treating method; and hydrophilically treated heat exchanger fins.
摘要:
A method of refining beet juice containing a colorant wherein the beet juice is contacted with an adsorbent composed of a dehydrated solid of a coprecipitated substance formed by insolubilizing metallic compounds in an aqueous solution. The adsorbent contains either a calcium or magnesium compound and also either an aluminum or iron compound. The process is conducted in a temperature range of 40.degree.-100.degree. C.
