Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To enable stable operation for a long time even if HFC refrigerant is used by using esters lubricating oil as refrigerator oil and using a polyester film covered with carbodiimide as a plastic insulation film. SOLUTION: Refrigerator oil containing esters oil composed of polyhydric alcohol such as pentane erythritol and fatty acid having the number of carbons of 6 to 10 as basic oil is used. Polyester (polyethylene terephthalate) insulation films 22 covered with carbodiimide are provided between an iron core 4A of a stator 5 and a main coil 4-1 and between the iron core 4A and an auxiliary coil 4-2. Moreover, the same polyester insulation film 23 is provided between the main coil 4-1 and the auxiliary coil 4-2. A carbodiimide component which enters HFC refrigerant due to the elution and sampling from these polyester insulation films 22, 23 contributes to the prevention of the deterioration of esters lubricating oil.

Abstract: PROBLEM TO BE SOLVED: To recognize at a glance that a flap has been unsealed unjustly to prevent unjust unsealing. SOLUTION: The packaging bag 1 is formed of a front sheet 2, a rear sheet 3 and a flap 4 wherein contents are put from an opening 6 into the packaging bag 1.

On the side of the operator's CRT device receiving the instruction, the operator recognizes the contents of the instruction by a screen 107 and returns a response to the supervisor's CRT device. The supervisor's CRT device receiving the response checks the response and transmits the display instruction on an operation screen 104 to the operator's CRT device.  An operation picture 108 is displayed on the operator's CRT device and the operator starts operation.
