摘要： PURPOSE:To obtain a distributor having high acid-proof performance and contamination-proof performance, and causing no degradation of insulation, by adding a carbon fluoride series surfactant. CONSTITUTION:Thermoplastic or thermosetting resin having good insulation performance is employed as the material for a cap 1. Said resin and reinforcing material are agitated through a high speed mixer, and a carbon fluoride surfactant is added to them under fused condition. Here, the carbon fluoride surfactant is a compound containing fluorine and carbon, produced by substituting hydrophobic group hydrogen atom in hydrocarbon surfactant entirely or partially with fluorine atom. Consequently, wetting performance between resin and reinforcing material is improved, thereby contact tightness or bonding force is increased. Thereafter, it is pelletized by means of an extruder and injection molded. Thus produced mold has a low surface tension, high medicine resistance and heat resistance and improved ozone resistance and contamination resistance.

摘要： PURPOSE:To enhance the dimensional stability and molding ability of a distributor cap having an electrically insulating wall in which high voltage connecting terminals are embedded, by forming the insulator with the use of thermoplastic resin having a satisfactory flame resistant capability and a reinforcing member. CONSTITUTION:A cap for a distributor is composed of an electrically insulating wall, and at least one or two high voltage connecting terminals belonging to an ignition device for an internal combustion engine and embedded in the above- mentioned wall. In such a cap, the insulator is formed of thermoplastic resin having a satisfactory flame resistant capability and a reinforcing member. As to the flame resistant thermoplastic resin, polybutylene-terephtalate is used, and as the reinforcing member, glass fibers and talc are used. Further, there may be used glass fibers and silicon, or glass fibers and a mixture of talc and silicon dioxide for the reinforcing member.

摘要： PURPOSE:To obtain sufficient sensitivity in the emission wavelength region of a semiconductor laser and to improve resolution and durability by using tau-type and/or eta-type metal-free phthalocyanine as an electrostatic charge generating material and a specified compd. as a charge transfer material. CONSTITUTION:A layer contg. a charge generating material and a layer contg. a charge transfer material are formed on a conductive substrate to obtain a composite type electrophotographic sensitive body. As the charge generating material, metal-free phthalocyanine of a type selected from tau-type, tau'-type, eta-type, and eta'-type is used, and as the charge transfer material, compds. represented by the formula, are used, in which R1 is alkyl or alkoxy, X is -CH2-, -O-, -S-, or -CHR2- and R2 is 1-4C alkyl. Such a composite type photosensitive body is obtained, e.g., by forming a layer contg. the charge generating material on a conductive substrate and on this layer a layer contg. the charge transfer material. The use of a combination of such a charge generating and charge transfer materials enhances sensitivity even in a long wavelength region, and the obtained photosensitive body is especially suitable for a semiconductor laser printer using a semiconductor laser as a light source.

An amine compound having a triazing ring represented by the formula VI or an epoxy resin or the like is used as a hardening agent. A charge transfer substance represented by the formula VII is contained together with said binder and said hardening agent in a charge transfer layer, thus forming a composite type electrophotographic plate. This plate has high surface hardness and abrasion resistance, and superior durability.
