摘要:
The present invention provides an oral composition comprising crystalline cellulose, and one or more surface active agents selected from the group consisting of alkyl glycoside, polyglycerin fatty acid ester, sucrose fatty acid ester and betaine, which has an excellent shape-holding ability and dispersibility in an oral cavity, does not change a taste of juice after teeth brushing, in addition, has excellent stability with time not causing solid-liquid separation. Moreover, the present invention provides an oral composition comprising a cationic bactericide and crystalline cellulose, which can effectively prevent an oral cavity disease such as a periodontal disease, dental caries and the like by enhancing an ability of the cationic bactericide to reside on a tooth surface.

An image heating apparatus for heating an image formed on a recording material includes a heating member, a backup member that cooperates with the heating member to form a nip for nipping and conveying the recording material, and a conveying member provided downstream of the nip in the traveling direction of the recording material. In such a construction, the conveying member is provided closer to the backup member than the heating member.
摘要:
A hydrocracking catalyst has a carrier that has particles of a compound oxide and a binder present between these particles, and at least one metal component selected from Group 6, Group 9 or Group 10 of the Periodic Table supported on the carrier. The catalyst has a median pore diameter of 40 to 100 Å and the volume of pores whose pore diameter falls within a range of 40 to 100 Å is at least 0.1 mL/g. Moreover, the volume of pores of the catalyst whose pore diameter falls within a range of 0.05 to 5 &mgr;m is 0.05 to 0.5 mL/g, and the volume of pores whose pore diameter is 0.5 to 10 &mgr;m is less than 0.05 mL/g. This catalyst is mechanically strong enough for practical use and has a high conversion rate and middle distillate selectivity in hydrocracking of hydrocarbon oils, particularly vacuum gas oil.

An indium oxide-tin oxide powder for ITO display devices etc. with only slight variance in properties such as average particle diameter and apparent density is prepared stably with good controllability and at low cost: (1) by electrolyzing indium as an anode, calcining or roasting the indium hydroxide obtained and combining the resulting indium oxide powder with a tin oxide powder; (2) by electrolyzing tin as an anode, calcining or roasting the metastannic acid obtained and combining the resulting tin oxide powder with an indium oxide powder; (3) by simultaneously electrolyzing indium and tin as separate anodes and then calcining or roasting the resulting mixed precipitate of indium hydroxide and metastannic acid to produce an indium oxide-tin oxide powder; or (4) by electrolyzing an alloy of indium and tin as an anode and then calcining or roasting the resulting precipitate of indium hydroxide and metastannic acid to produce an indium oxide-tin oxide powder.
摘要:
A method of and apparatus for supplying power during EDMing in which reverse polarity pulses are used to inhibit electrolytic activity. A main voltage pulse of a certain polarity and an auxiliary voltage pulse, preceding the main voltage pulse of the same or reverse polarity, are applied across a machining gap during the on time of a main gate signal and until a discharge is detected. The ratio of the number of auxiliary voltage pulses of regular polarity to those of reverse polarity is set to a desired value depending upon machining conditions, to thereby obtain a good compromise between the conflicting requirements of achieving a high machining rate, while inhibiting undesirable electrolytic activity.
摘要:
Process for analyzing anions in a liquid by means of an ion exchanger and by complex formation with specific anions by addition of polyhydric alcohol. Sensitivity is increased owing to the fact that the complex of specific anions with polyhydric alcohol has a high activity as acid.
摘要:
A joint is made between two pieces of steel which have been preheated to a temperature To (.degree.C.) near their abutting surfaces by subjecting first to flashing and then to upsetting. When the ultimate flashing rate is V (mm/sec.), a current whose density I (A/mm.sup.2) is not lower than ##EQU1## is passed during the upsetting process to melt the abutting surfaces. With a mean upsetting rate of not lower than 50 mm/sec., only the molten metal is rapidly squeezed out from the abutting surfaces. Then, the upset current is cut off while applying a final upsetting force that is as low as under 5 kg/mm.sup.2.
