Abstract: PURPOSE: To improve oiling characteristics by smoothly discharging refrigerant gas which is mixed or generated in an oil passage. CONSTITUTION: A slit 31 is formed on the rotary center 1 side of an oiling pipe 27 till a point (n) which is crossed with a vertical line (m) extending from the reverse rotary center side of a lower end opening port 28, and also a chain of groove 22 and a relief groove 32 extending to the lower part are formed on a crank shaft 11 including upper and lower journals 18, 17 and a lightening part 19 which is formed between both journals 18, 17. It is thus possible to smoothly discharge gas which is mixed into the oiling pipe 27 and gas which is generated inside, improve oiling characteristic, and improve durability.

Abstract: PURPOSE: To improve oil supply characteristics of a closed type motor-driven compressor by smoothly discharging refrigerant gas mixed in or generated in an oil passage. CONSTITUTION: A serial groove 22 including upper/lower journals 18, 17 and a lightening part 19 therebetween is formed to a crankshaft, while a slit 31 is extendedly formed to a point n intersected with a vertical line extended from the reverse rotational center side of a lower end opening on the rotational center 1 side of an oil supply pipe 27, so that gas mixed in the oil supply pipe 27 and generated therein can be smoothly discharged, the oil supply performance and durability of a closed motor-driven compressor can be improved.

Abstract: PURPOSE:To provide a solenoid valve of instantaneous electrification type which produces low operational sounds and is strong against foreign matter. CONSTITUTION:A valve 17 corresponding to a valve opening solenoid 28 is provided. A first plunger 15 provided on the outer peripheral surface with a lightening part and a second plunger 26 provided also with a lightening part corresponding to a valve closing solenoid 29 are disposed to hold the valve opening condition with a position holding device 19 and stage part 12. Then, while instantaneous electrification is made possible by the position holding device 19 to save energy, foreign matter and abrasion powder are accumulated in the lightening part of the plunger to prevent the increase of slide resistence.

Abstract: PURPOSE:To provide a quick conduction linear solenoid in which the operational noise is reduced. CONSTITUTION:The linear solenoid comprises a first plunger 15 provided with a valve 17 corresponding to a first solenoid 28, and a second plunger 26 corresponding to a second solenoid 29, wherein the open valve state is sustained by means of a position holding unit 19 and a step part 12. The position holding unit 19 allows quick conduction to save energy and reduces noise by preventing magnetic contact of the plunger.

Abstract: PURPOSE:To obtain an instantaneously electrifying-type solenoid valve having a little operating sound, CONSTITUTION:A first plunger 15 on which a valve 17 is provided is so arranged as to face a valve opening solenoid 28, and a second plunger 26 is so arranged as to face a valve opening solenoid 29, and the valve opening state is held by a position holding device 19 and a stepped part 12. Thereby, instantaneous electrification is enabled by the position holding device 19, and energy saving is attempted, and magnetic contact of the plunger is prevented, so as to obtain silence.

Abstract: PURPOSE:To prevent a defect in operation due to frosting, icing, etc., at a movable part in a storage room and improve the stability of vending operation by performing both or either of a door and an in-box conveyance device in idling operation irrelevantly to vending operation. CONSTITUTION:The door 16 or in-box conveyance device 17 is placed in idling operation through a timer 66 and an in-box temperature sensor 67 irrelevantly to whether or not vending operation is carried out, when the possibility of vending is low, for example, in nighttime, one hour after defrosting is completed, at the time of recooling operation at the time of a power failure, maintenance, etc., or when the in-box temperature nearly reaches 0 deg., namely, when an idling operation control means 68 decides that set conditions are met. Therefore, the development of local frosting and icing can be prevented at the rotary and slide parts of the in-box conveyance device 17 and the seal part of the door 16. In this idling operation, steps of vending are given priority, so even when the idling operation and vending operation are performed simultaneously, the cycle time of the vending operation never becomes long.

Abstract: PURPOSE:To prevent a ball, provided on the halfway of a wire, from coming off from a ball storage recessed part of a drum. CONSTITUTION:A ball 3 fixed to a wire 2 is stored in a recessed part 4 of a drum 1, and on top of the ball, a pin 8 is extended from a pin hole 9, to further extend an end part of the pin 8 folded into a boss 6. A flange 13 of a different shaped part 12, engaged with a boss part of a rotary shaft 7, is positioned in a fold part of the pin 8. In this way, the ball 3 and the pin 8 can be easily and surely prevented from coming off, and instantaneously reversely driving can be also performed.
