摘要： PURPOSE: To evaluate residual gas in an extra high vacuum, and analyze a trace quantity gas component discharged from a sample having the low surface area by arranging an ionizing area so as to be opposed to a sample or a gas- like sample introducing port, and specifying a distance between these. CONSTITUTION: In an ionizing chamber 1, an ionizing area 4 which accelerates a thermoelectron generated and emitted from an electron beam source 2 by an electric field between counter electrodes 3 and is ionized by colliding with a sample gas molecule, is arranged on an extension of a gas-like sample introducing pipe 6. However, since the motional directional distribution of an introducing sample gas molecule expands from the axial direction of the introducing pipe 6 as a diameter of a gas-like sample introducing port 5 becomes large to a length of the introducing pipe 6, when a diameter of the introducing port 5 is not less than 1/10 of a length of the introducing pipe 6, the area 4 is arranged so as to be opposed to a central extension line of the introducing port 5. Since a distance between the introducing port 5 and the area 4 is determined by a molecule diameter and partial pressure of the sample gas molecule to be measured, various values are taken up according to a measuring demand.

摘要： PURPOSE: To provide a mass analyzer in which the decrease in the detecting limit due to the remaining gas component is prevented and which can sufficiently deal with the analysis of infinitesimal quantity of the components. CONSTITUTION: A mass analyzer 1 comprises analyzing mechanisms 11, 13, 15 for analyzing the mass of a sample, partition walls 5 for partitioning analyzing chambers 3 for containing the mechanisms 11, 13, 15, and gas supplying mechanisms 7, 9, 25, 27 for supplying predetermined gas to the outer peripheries of the walls 5 to cover the outer peripheries of the walls with the gas. A mass analyzer 67 comprises a converter 73 for converting the sample to ion, a separator 75 for separating the ion converted by the converter 73 according to mass, a detector 77 for analyzing the mass of the sample by detecting the ion separated by the separator 75, and a heater 85 for heating the surface of the separator 75 to 80 deg.C or higher during the mass analysis. Accordingly, the decrease in the detecting limit due to the component included in the atmosphere and the gaslike substance in high vacuum can be prevented.

摘要： PURPOSE:To prevent ice coating on a jetting portion of a nozzle for positive heat exchange between a refrigerant and water to stably produce sherbet-shaped ice. CONSTITUTION:Before ice making with a temperature of water M exceeding 0 deg.C, a nozzle 13 is positioned below water surface to jet a refrigerant R in the water. At the time of ice making with a temperature of water M reaching 0 deg.C or lower, a first electromagnetic valve 33 is opened for extraction of water M in an ice heat storage tank 1 into a reserve tank 31 through a first piping 29. Accordingly, water M in the ice heat storage tank 1 is lowered in level, so that the nozzle 13 is caused to be positioned above a water surface M. In this position, the refrigerant R is jetted to prevent ice coating on the nozzle 13.

摘要： PURPOSE:To suppress a large temperature change due to non-azeotropic mixture refrigerant and to improve a refrigerating capacity by forming an evaporator of a tube for feeding the refrigerant and cooling fins, and so forming a sectional area of a refrigerant flow rate flowing in the tube as to be sequentially reduced along a flowing direction of the refrigerant. CONSTITUTION:An evaporator 9 is formed of a tube 15 connected to a refrigerating tube and fins 17. The tube 15 is so set that a sectional area of refrigerant flow rate is sequentially reduced from an inlet side 15a to an outlet side 15b. Since a flowing velocity of the refrigerant flowing in the tube 15 is sequentially accelerated toward the outlet side 15b in the evaporator 9, a heat exchanging amount is increased. On the other hand, as a pressure loss is increased, a temperature gradient at the time of phase change of mixed refrigerant and an evaporating temperature are held substantially the same, and a temperature difference of inlet and outlet sides of the evaporator 9 can be suppressed to a small value. Accordingly, frosting, icing do not occur, and an efficient refrigerating can be conducted.
