摘要： PURPOSE:To reduce the consumption of electric power and to simplify the constitution of a rotary shaft by constituting a rotor provided with an evaporation face of a material made of metal and arranging an electrically-conductive coil for induction heating to the opposite side of the evaporation face of this rotor. CONSTITUTION:A rotor 2 made of metal is provided to the tip of a rotary shaft 3 introduced into a vacuum vessel 1 and a funnelform evaporation face 4 is formed in the front face of this rotor 2 and an electrically-conductive coil 5 supported in the vessel is arranged in the opposite side of this face. A high-frequency electric power source 6 feeding high-frequency electric power to the coil 5 from the outside is arranged to the outside of this vessel 1. In this apparatus, raw liquid is fed through a feed pipe 7 and evaporated components are taken out through a takeout pipe 8 and the residue is taken out through a takeout pipe 9. Therefore the consumption of electric power is reduced in comparison with such a case that the rotor 2 is subjected to radiation heating by means of a heating resistor and the structure of the rotary shaft 3 is simplified in comparison with the case heating the rotor 2 by a heating element.

摘要： PURPOSE: To wash off oils and fats bonded to the interior of hole or blind hole of an article to be washed having the porous blind hole. CONSTITUTION: An article 6 to be washed is immersed in a heated first washing soln. 8 in a washing chamber 1 to be washed and the washed article 6 is fed in a vacuum heating chamber 2 from the washing chamber 1 and, after the fed-in article 6 to be washed is cooled, the vacuum heating chamber 2 and the washing chamber 1 are reduced in pressure. By this constitution, the article 6 is washed with the vapor evaporated from the heated first washing soln. 8. At this time, the first washing soln. 8 condensed on the cooled article 6 enters the hole and blind hole in which no inert gas remains of the article 6 to wash off the oils and fats bonded to the interiors of the hole and blind hole of the article 6. Finally, the washed article 6 is dried under vacuum.

摘要： PROBLEM TO BE SOLVED: To cover a bottle on a shelf without using a spacer even when there is a vacant shelf. SOLUTION: A freeze vacuum drying device 1 has vertically movable shelf plates 101 to 103 disposed in a vacuum tank 11, guide members 201, 202 and moving units 701, 702. Thus, only when the plates 101 to 103 are steadily stopped at an entrance/exist for introducing and discharging a vial bottle filled with a chemical to be freeze vacuum dried, the units 701, 702 are operated to closely contact the members 201, 202 with the sides of the plates 101 to 103 so that the bottle may not drop from the side on the plates. Thus, since the members 201, 202 may not be fixed to the plates 101 to 103, the plates 101 to 103 can be closely contacted, and the device can be reduced in size. Even when there is a vacant shelf, the shelf may not be broken even by not using the spacer like prior art.
