Abstract: An endoscope apparatus includes: a plurality of connection portions to which an endoscope can be connected, respectively, wherein a priority setting portion sets a connection priority of the plurality of connection portions, a drive portion supplies a drive signal to one endoscope and a control portion that controls so that the drive portion supplies the drive signal to any one endoscope only based on the connection priority. The endoscope apparatus further includes an identification portion that identifies the kind of endoscope based on a resistance value of a specific resistance that differs according to a kind of the endoscope that is arranged in the endoscope, and that is detected by cancelling a contact resistance in the connection portion.

Abstract: An endoscope system includes: a photoelectric conversion element that subjects an image formed by an optical lens to photoelectric conversion; a contour enhancing section that detects an edge component in a picked-up image subjected to the photoelectric conversion, thereby generating a contour enhancement signal; an electronic zoom region determining section that determines an electronic zoom region in the picked-up image based on a strength of the contour enhancement signal; an instruction section that provides an instruction for enlargement/reduction of the image; a parameter setting section that sets a zoom parameter for an electronic zoom section according to the of the instruction section; and the electronic zoom section that upon an input of the instruction of the instruction section, performs an electronic zoom of the picked-up image for the electronic zoom region determined by the electronic zoom region determining section, according to the parameter set by the parameter setting section.

Abstract: The present invention is intended to provide a process for forming an electrodeposition coating film, wherein generation of gas pinhole is reduced and coating film appearance is excellent without using a specific resin as a binder resin. The present invention relates a process for forming an electrodeposition coating film having reduction of generation of gas pinhole, comprising a step of electrocoating by immersing an article to be coated in a cationic electrodeposition coating composition, wherein, the cationic electrodeposition coating composition comprises 10 to 30 parts by weight of a pigment comprising zinc oxide based on 100 parts by weight of a solid content of the coating composition, and the content of zinc oxide contained in the pigment is 0.25 to 5 parts by weight based on 100 parts by weight of the pigment.

Abstract: There are provided a method and apparatus capable of conveniently and rapidly inspecting a warpage of a rod. A rod to be inspected is rolled down an inspection bed and light shielded by the downwardly rolling rod is detected by a line sensor as a one-dimensional image signal. A positional fluctuation value of the downwardly rolling rod is obtained from a two-dimensional image signal obtained from the one-dimensional image signal. Based on the positional fluctuation value, the degree of the warpage of the rod is determined. The shielded light signal is detected in the vicinity of one end of the downwardly rolling rod to be inspected.

Abstract: To provide a method for producing a pigment dispersing resin varnish for cationic electrodeposition paint, wherein the flow properties and appearance of the resulting electrodeposition coating film are not compromised when using as a solvent a compound that is not volatilized into the atmosphere but remains in the electrodeposition coating film during the onium conversion of a pigment dispersing resin, as well as a cationic electrodeposition resin composition allowing HAPs to be eliminated and volatile organic carbon compounds to be reduced (VOC reduction). A method for producing a pigment dispersing resin varnish for use with cationic electrodeposition paint, wherein a solvent comprising a polyalkylene oxide compound represented by the following formula is used to produce a resin varnish which has been obtained from a cationic epoxy resin composition having amino groups, phosphonium groups, or sulfonium groups.

Abstract: A cationic electrodeposition coating composition is provided which contains blocked isocyanate curing agent which is blocked with a substance not recognized as a HAPs (hazardous atmospheric pollutant). The cationic electrodeposition coating composition of the present invention contains a cationic group-containing epoxy modified base resin and a blocked isocyanate curing agent, wherein said blocked isocyanate curing agent is obtained by reacting a polyisocyanate compound with, as a blocking agent, a terminal primary OH-containing propylene glycol monoalkyl ether and expressed by the formula RO(CH(CH3)CH2O)nH (where R is an alkyl group having 1 to 8 carbons, which may be branched, and n is 1 to 3).
