IPC: F25B13/00
Filed: 1987-10-20
Abstract: PURPOSE: To achieve a miniaturization of an outdoor side second heat exchanger relatively by connecting bypass piping to side of a room side heat exchanger bypassing the outdoor side second heat exchanger to the liquid delivery side of a gas/liquid separator to significantly improve the heat exchange efficiency of the outdoor side second heat exchanger. CONSTITUTION: A liquid component delivered from a liquid/gas separator 13 flows into a room side heat exchanger 5 through bypass piping 20 so that a steam component enriched with a low boiling point refrigerant flows into the outdoor side second heat exchanger 14. Therefore, the lowering of the heat exchanger efficiency as caused by the adhesion of a liquid refrigerant to a pipe wall is prevented to significantly increase the heat exchange efficiency in the outdoor side second heat exchanger 14. The steam component enriched with the low boiling point refrigerant separated by the gag/air separator 13 flows into a fractioning tower 6 through a second throttle valve 16 and liquefied in contact with the liquid component, a gas/liquid contact, from a storage tank 9 in a process of rising in the fractioning tower 6.  The components yet to be liquefied is further liquefied by a cooler 11 to be stored into the storage tank 9 in a short time.

Title: Electron beam irradiator
Inventor: SHIMAOKA YOSHIHARU
IPC: G21K5/10
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To prevent an electron beam from being shielded by falling matters by bending at least the central part on the lower surface side at the grid part of a grid window. SOLUTION: A grid window 7 has many parallel grids 30 curved to project upward (vacuum side). Since a high voltage is applied between a filament 3 and a vacuum chamber 1, thermoelectrons are induced by that voltage and projected through a window foil 5 toward an object to be processed. A part of the electron beam strikes against the grid 30 to disappear. The majority of the electron beam does not pass the fringe part but passes through the central part of the window foil 5. Fragments of insulator and residues in the vacuum chamber fall onto the window foil or the grids. Since the grid is curved, the falling matter R is not caught by the window foil or the projecting part (central part) of the grids but slips down and collected at an end part. Since cuts 37, 38 are made, the falling matter R can be pushed in to the frame side 34.  According to the structure, even a significantly wide electron beam cause no trouble.
