摘要:
A heat-developable photosensitive material of which thermal fogging is markedly suppressed without detriment to image characteristics such as sensitivity, which is prepared by forming a single layer or multiple layers of a heat-developable photosensitive element comprising at least (a) an oxidation-reduction image-forming component comprising a long-chain fatty acid silver salt and a reducing agent, (b) a photosensitive silver halide or/and a photosensitive slilver halide-forming component, (c) a binder, and (d) at least one member selected from the compounds represented by the following general formula:HOOC--R--COOHwherein R represents an alkylene or alkenylene group of at least 4 carbon atoms which may be linear or branched, on a support.

A cosmetic emulsion of low viscosity which comprises (a) 0.2 to 5 wt % of an emusifier, (b) 0.5 to 10 wt % of an oil and (3) 85 to 99.3 wt % of a water phase. The emusifier (a) consists essentially of a dimethylpolysiloxane-polyalkylene copolymer, a surface active agent having an HLB value not smaller than 10, and a linear, saturated higher alcohol having from 12 to 22 carbon atoms. The relative ratios of the dimethylpolysiloxane-polyoxyalkylene copolymer, the surface active agent and the higher alcohol lie within the polygon bounded by the points of a ternary composition diagram of the annexed figure.When the emulsion is applied to the skin, it gives refreshing feeling to the skin without any stickiness. It also gives appropriate moisture retentivity to the skin.

Ceramic materials suitable for use in varistors, enabling the same to function both as such and as capacitors. The ceramic compositions comprise a major proportion of SrTiO.sub.3, the balance being (1) one or more of Nb.sub.2 O.sub.5, Ta.sub.2 O.sub.5, WO.sub.3, La.sub.2 O.sub.3, CeO.sub.2, Nd.sub.2 O.sub.3, Pr.sub.6 O.sub.11, Dy.sub.2 O.sub.3, Y.sub.2 O.sub.3, and Sm.sub.2 O.sub.3, for making the compositions semiconductive, and (2) one or more of V.sub.2 O.sub.5, Cr.sub.2 O.sub.3, CuO, Cu.sub.2 O, MoO.sub.3, and MnO.sub.2, for improving the nonlinear volt-ampere characteristic of the compositions. If desired, for improving the coherency of bodies molded from the compositions, there can be added one or more of GeO.sub.2, ZnO, B.sub.2 O.sub.3, and PbO. For use as varistors the mixture of the above ingredients, all in finely divided form and made coherent with a binder, is molded into desired shape under pressure. The moldings are first fired in a nonoxidative atmosphere and then further heated in an oxidative atmosphere. Electrodes can be formed as by silver painting.

摘要:
The present invention relates to an elastic tubing pump and more particularly to an elastic tubing pump. The pump has an elastic tube communicating with a liquid supply source, a pressing means for pressing at least two points of a section of the elastic tube to seal the liquid therein, a driving means for pushing the pressing means in one direction of the elastic tube, a locking means for firmly holding the elastic tube from being moved by the pressing means, a shifting means for unlocking the locking means according to the driving operations of the driving means and for advancing the elastic tube by the length of its compressed section. The driving means can accelerate to compensate for the possible decrease in the liquid's flow through the tube during a time of shifting the elastic tube by one section's length.
