    Abstract: PROBLEM TO BE SOLVED: To provide an automatic ice making device for a refrigerator, in which an ice making finishing detecting sensor causes faulty operation hardly, and air invades hardly through a clearance of the refrigerator. SOLUTION: Punching work is applied on soft polyethylene form having both of flat surfaces, by a cutting edge to obtain a simple predetermined configuration and the form is abutted against an ice making finishing detecting sensor 2, arranged on the rear surface of an ice making pan 1, while being compressed whereby the ice making pan 1 is contacted closely with an elastic soft heat insulating member 5, and an ice making pan assembly having no clearance is obtained. The elastic soft heat insulating member 5 is provided with both of flexibility and elasticity, whereby a constitution having no clearance substantially can be obtained, an ice making capacity is stabilized, labor to confirm the upper and lower surfaces of the elastic soft heat insulating member 5 can be omitted to effect smoother assembly work, productivity is improved remarkably compared with the molding in a molding tool, and economical effect can be obtained.

    Abstract: PURPOSE:To obtain a resin compsn. which has high electrical conductivity and little variation in electrical conductivity, by subjecting a slurry contg. an electrically conductive power and a polyolefin crystallized from a polyolefin- dissolving solvent to a solid-liquid separation treatment. CONSTITUTION:A polyolefin and an electrically conductive power are mixed with a polyolefin-dissolving solvent to dissolve the polyolefin in the solvent and to disperse uniformly the powder in the soln. At least 1pt.wt., pref. 5-30pts. wt. polyolefin is added to 100pts.wt. solvent. The quantity of the electrically conductive powder to be added varies depending on the desired volume resistivity of the polyolefin. A polyolefin-nondissolving poor solvent is added to said solvent contg. the polyolefin dissolved therein and the powder dispersed therein to crystallize out the polyolefin. A slurry contg. the crystallized polyolefin and the powder is subjected to a solid-liquid separation treatment to obtain a mixture of the polyolefin and the powder.

    Abstract: PROBLEM TO BE SOLVED: To achieve a rationalization of material costs and improvements in transportation and assembling work, by shortening an evaporation refrigerant return tube in a refrigerator in which a cooler is provided at the center part of the rear of the body of the refrigerator. SOLUTION: A piping part 16 on which a capillary tube 15 for a refrigerant is integrally soldered one back and forth and a half parallel with a part of an evaporation refrigerant return tube 14 to secure a heat exchange performance is arranged on a cooling system above a cooler without bypassing the evaporation refrigerant return tube 14. Moreover, the ratio of the length is set at about 2:1 between the capillary tube 15 for the refrigerant and the evaporation refrigerant return tube 14. This constitution achieves a saving of resources of the evaporation refrigerant return tube 14, a prevention of poor bending in the working process with the miniaturization of the piping part 16 and improvements in assembling work.
