Abstract: A method of making a composite structure including at least a plating film disposed on a substrate having at least a surface portion formed from a metallic base material. The method includes the steps of discharging a composite plating solution containing insoluble particles from a nozzle and impacting the composite plating solution on the surface portion of the substrate at a predetermined flow rate. During at least a portion of the discharging and impacting steps, the surface portion of the substrate is abraded with the insoluble particles in the plating solution discharged from the nozzle. A voltage can be applied between the base material and the nozzle, which are electrically connected by the plating solution, to thereby deposit a plating film on the surface portion of the substrate by electroplating.

Abstract: A camera having an autofocus function, independent of a photographing optical system, includes a photographing optical system including synthetic resin lenses and an autofocus optical system, provided independent of the photographing optical system, having at least one synthetic resin lens and a stop decentered in a direction perpendicular to the optical axis of the synthetic resin lens. Thus, in the camera, the shift of the imaging position of the photographing optical system which is caused by an ambient temperature or humidity change is favorably corrected, and good photography can be performed.

Abstract: A screw head for an injection molding machine is mounted to a distal end portion of a screw, and includes a trunk portion and a screw portion, and an undercut portion formed between the trunk portion and the screw portion, wherein a relationship between a shaft diameter e of the undercut portion and a nominal diameter f of the screw portion is defined as:0.74f.ltoreq.e.ltoreq.0.85fand a relationship between the nominal diameter f of the screw portion and a radius r of curvature of the undercut portion is defined as:0.5f.ltoreq.r.

Abstract: A thermal transfer printing sheet comprising a substrate having a coating comprising an anthraquinone dye of the formula: ##STR1## wherein R is C.sub.1-6 -alkyl, C.sub.4-8 -cycloalkyl or C.sub.2-6 -alkenyl;R.sup.1 is C.sub.1-6 -alkyl or C.sub.2-6 -alkenyl;andR.sup.2 is H or C.sub.1-6 -alkyl or C.sub.2-6 -alkenyl,and its use in the preparation of a printed image on a receiver sheet by selective heating of the transfer sheet, in accordance with a pattern information signal, while in contact with the receiver sheet.

Abstract: A method of shaping a body of thermoformable material containing continuous filaments comprising selecting a shaping polymer material having a glass transition temperature which is greater than the glass transition temperature of the thermoformable material of the reinforced body, locating the reinforced thermoformable body between a pair of sheets of the selected shaping polymer, heating the assembly of reinforced body and shaping polymer sheets to a temperature at which the reinforced material can be formed and the shaping polymer can be stretched and applying a differential pressure preferably of not greater than 10 atmospheres, between opposite sides of the assembly of shaping polymer sheets and thermoformable body to induce a desired shaping of the reinforced thermoformable body and cause rearrangement of the filaments relative to each other.

Abstract: 1,4-Diaminoanthraquinone-2,3-disulfonic acid or salt thereof and 1,4-diaminoanthraquinone-2,3-dinitrile which are intermediate of anthraquinone dyes are economically prepared by allowing 1,4-diamino-2,3-dihalogenoanthraquinone to react with alkalimetal sulfite in aqueous solution in the presence of quaternary ammonium or phosphonium compound, while water is being removed, to obtain 1,4-diaminoanthraquinone-2,3-disulfonic acid or salt thereof and, if necessary, cyanogenating the reaction mixture above without removing the disulfonic acid or salt thereof produced above to obtain 1,4-diaminoanthraquinone-2,3-dinitrile. The quaternary ammonium or phosphonium compound is recovered from and re-used for the reactions above.

Abstract: A staining technique for specimens which involves the sequential treatment of specimens with periodic or hydrochloric acid, thiocarbohydrazide or thiosemicarbazide, and silver methenamine. The technique, when using periodic acid, provides an excellent stain to evaluate glycomacromolecules and fibrovascular tissue and to conduct a broad spectrum of staining procedures for all modes of microscopy. Use of hydrochloric acid facilitates evaluation of cell nuclear DNA and chromatin.

Abstract: There are described construction parts for gaseous hydrogen containing media which construction parts are made of a nickel alloy containing 40 to 70% nickel, 15 to 30% chromium, 0 to 20% cobalt, 5 to 10% molybdenum, and 0 to 20% iron and which construction parts have optimum hydrogen permeation prevention properties. For this purpose, the alloys contain 0.5 to 0.8% manganese and the parts are provided with a 1 to 10 .mu.m thick oxide coating by treating at a temperature of 850.degree. to 1000.degree. C. in an oxidizing atmosphere.

Abstract: A solid fatty polyamide dissolved in a volatile organic solvent has been found effective for preparing cavities of teeth for restoration. For example, when this solution is applied to a cavity in the form of a dental cavity varnish, the organic solvent may be evaporated to leave behind a continuous polyamide film which is compatible with methacrylate resin type restoratives. Solid fatty polyamides are generally derived from the reaction product of partially polymerized unsaturated fatty acids with aliphatic diamines. The present invention relates to methods for preparing cavities with these polyamides as well as to compositions containing these polyamides.
