Abstract: A digital image forming apparatus which detects a center of a book document when reading and writing an image of the document, including a document, a document board on which the document is set, a reading device for reading the document by scanning the document, an A/D converter for converting an analog signal which is read by the reading device to a digital signal, a signal processor for processing the digital signal, including a first detector for detecting the existence of a dark portion in the image of the document and judging the document to be a book document if the document image has the dark portion, based on the signal corresponding to at least two lines on the document in a scanning direction, or in a direction perpendicular to the scanning direction and a second detector for detecting a center portion of the document on the basis of each center dark portion of each signal of the lines if the document is judged to be a book document, and a writing device for writing the digital signal on a photocon

Abstract: A resin composition for forming conductor patterns comprising a photo curable resin, a photopolymerization initiator, a thermosetting resin, agent for the thermosetting resin, photosensitive semiconductor particles, and if necessary a polyfunctional unsaturated compound is suitable for forming very fine conductor patterns in a build-up method.

Abstract: A printed circuit board has a resist layer made from a photo-setting resist composition containing:(A) a polyfunctional unsaturated compound which is solid at room temperature,(B) a polyfunctional unsaturated compound which is liquid at room temperature,(C) a photopolymerization initiator,(D) an epoxy resin,(E) at least one member selected from the group consisting of:(i) a curing agent for the epoxy resin and either melamine or the derivative thereof, and(ii) a compound having a 2,4-diamino-s-triazine ring and an imidazole ring in the molecule.

Abstract: A photo curable diallyl phthalate resin composition characterized by containing 0.1 to 10 parts by weight of an agent for preventing back side undesirable curing and 20 to 100 parts by weight of a filler per 100 parts by weight of a diallyl phthalate prepolymer is particularly suitable for a partly additive process for forming a solder resist effective for preventing back side undesirable curing by ultraviolet light and having resistance to release of substances from the solder resist for deteriorating properties of plated copper film as well as for giving good mechanical properties.

Abstract: A skin temperature measuring apparatus for diagonising disturbance of peripheral circulation of a patient having a cold air box including a thermo regulator of low temperature. A radiation thermometer is disposed in the cold air box for measuring the skin temperature of a test section of the patient's hand. The cold air box includes a test section inserting unit through which the test section of the patient's hand is inserted into a positioning unit. The positioning unit properly positions the test section within a visual field of the radiation thermometer. A fan blows cold air to the positioned test section, thereby allowing simple and accurate measuring of the skin temperature, while avoiding unnecesary pain to the patient.

Abstract: An epoxy resin composition containing as a latent hardener a diaminotriazine-modified imidazole compound and dicyandiamide is improved in the usable life of an solder resist ink composition and can give a solder resist also excellent in resistance to an electroless plating bath.

Abstract: An epoxy resin composition comprising an epoxide compound, a guanidine compound, a filler, a thixotropic agent and an organic solvent and having a thixotropy index of 5 to 40 and a viscosity of 800 to 10,000 poises (at 20.degree. C.) is suitable for forming a resist film which is used in electroless metal plating with excellent heat resistance, solder resistance and corrosion resistance, and the like.

Abstract: During recyclic use of a chemical copper plating solution, counter anions to copper ions, anions formed by oxidation of a reducing agent, and carbon dioxide by absorption of carbon dioxide from air, which all have an inhibiting effect upon the plating, and also sodium ions having no inhibiting effect are accumulated in the plating solution.These accumulated ions can be removed by electrodialysis. Particularly, regeneration can be satisfactorily regenerated by adjusting the pH of used chemical plating solution to 2-11 before the electrodialysis, and using a selectively monovalent anion permeable membrane as an anion exchange membrane at the electrodialysis.

Abstract: The pH of a chemical copper plating solution is exactly measured for a prolonged time by utilizing a copper oxide prepared by etching metallic copper in an 0.1-1 N inorganic acid then oxidizing the etched metallic copper in an aqueous 0.1-1 N alkali metal hydroxide solution as a main electrode for pH measurement or reducing agent concentration measurement in terms of pH.A combination of the pH measurement with well known procedures for measuring concentrations of cupric ions and a complexing agent exactly measures the pH and the concentrations of a reducing agent, cupric ions and a complexing agent for a continuation of longer time than the conventional procedures.
