Title: Molecular pump
Inventor: OKAMOTO MASATOMO
IPC: F04D19/04
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent breakage and the like of piping and debacle in the case where a rotor is broken by slidably arranging a cylindrical middle shell fitted to an outer periphery of a stator in a circumferential direction and on an inside of a casing of a turbo molecular pump part, and arranging a clearance between the outer periphery of the middle shell and the casing. SOLUTION: When a rotor 4 is broken by stress corrosion cracking and the like during operation of a compound molecular pump 1, a lower part of the rotor 4 collides with a stator 7b, and is slidably rotated. Accordingly, rotational energy of the rotor 4 is consumed, and shock is released. When the rotor 4 which collides with a lower stator 7b is broken at a position showing with an arrow Z, a blade stage 2b is broken by upper bits, and the bits collide with the middle shell 7a. Since the middle shell 7a is formed in a thin wall, the middle shell 7a is deformed outward by collision with the bits. The middle shell 7a is slidably rotated in a circumferential direction, and thereby rotary energy of the bits is absorbed to cushion shock.

Title: Defrosting device for air conditioner
Inventor: IGA NAOKI
IPC: F25B47/02
Filed: 1990-02-06
Abstract: PURPOSE:To reduce a boiling sound of coolant during a defrosting operation and keep a defrosting efficiency by a method wherein each of capillary tubes divided into a plurality of segments is arranged at a pipe between a discharging pipe and a sucking pipe through a two-way valve and each of the capillary tubes is independently connected to a suction pipe. CONSTITUTION:A pipe 26 is connected between a discharging pipe 24 and a sucking pipe 23 of a compressor 16. To the pipe 26 are connected the capillary tubes 27 to 29 divided through a two-way valve 25. They are independently connected to the suction pipe 23 at merging points 23a to 23c. During a heating operation, an outdoor heat exchanger 18 is frosted, and a heating capability is reduced. In this case, two-way valves 25 and 20 are opened in response to a detected temperature of a heat exchanger temperature sensor 30. The coolant is flowed into the capillary tubes 19 and 22 so as to prevent a flow rate of the coolant of a main freezing cycle flowing in the indoor heat exchanger 21 from being reduced under an opened state of the two-way valve 25. A total sum of coolant passing through each of the capillary tubes 27 to 29 is the same flow rate at that of having no capillary tube and thus the coolant boiling sound is eliminated and the defrosting effect can be assured.
