摘要： PURPOSE:To efficiently and radically repel an unpleasant insect pest such as cockroach and prevent damage due to accident, etc., by providing a member containing an unpleasant insect pest repellent for preventing invasion of the unpleasant insect pest attracted by heat. CONSTITUTION:A coating film 7 containing an attracting repellent having effect on heat attraction is formed in the inside or the space opening of the bottom of a cooking device body. This coating film 7 is obtained by blending an urethane resin with a percutaneously effective cockroach repellent, preferably using a cockroach repelling material consisting of O,O-Dimethyl O-(p- cyanophenyl) phosphorothioate as the cockroach repellent and applying the blend in a ratio of 10mg/m expressed in terms of the repelling material. The coating is preponderantly applied to a holding member for supporting a printed circuit board 8 and also an extending part of a body bottom of passage to a heater 9 for heat insulation. This coating film has effect retaining the unpalatability over about 3 years under circumference practically used.

摘要： PURPOSE:To provide the piping member which is safe to a human body, can lessen the pollution on environment and can suppress the propagation of microorganisms by adding an antimicrobial agent to a resin for pipings at a specific ratio (wt.%), thereby forming the connecting piping member for a water purifier. CONSTITUTION:This piping member is used to connect the water purifier for removing the malodorous components of city water by utilizing active carbon, etc. The piping member is formed by adding 1 to 5wt.%. antimicrobial agent to the resin for pipings. A fluororesin or a silicone resin having water repellency may be added to the piping member. Further, an inorg. metal antimicrobial agent is used as the antimicrobial agent and a silver antimicrobial agent is used as this inorg. metal antimicrobial agent. The surface of a silica gel deposited with a thiosulfate silver complex is coated with the hydrolyzate of a tetraalkoxysilanee as the silver antimicrobial agent More specifically, the piping member is formed by kneading and adding 3wt.% silver antimicrobial agent 2 with and into the resin of, for example, an antimicrobial PVC pipe 1.
