Inventor: ASAI YOSHIMITSU
IPC: F04F3/00
Filed: 1980-11-26
Abstract: PURPOSE: To simplify the separation of mud, sand and the like from water in a tank  by sucking up the water to a higher level with the use of a vacuum discharge device  including a pump or the like and by water-cooling a sucking pipe in the intermediate  portion thereof.  
     CONSTITUTION: A water jet pump 1 is operated by opening a water valve E for actuating the water jet pump 1, and a vaccum tank 2 is evacuated by opening a vacuum  valve 2. When the degree of vacuum in the vacuum tank 2 comes to a predetermined  value, a suction valve B is opened to such muddy water into a vacuum tank 2. If the  temperature of water is relatively high, a water supply valve F for cooling a jacket 6  around a conduit 5 is opened to lower the temperature of water by cooling thereof for  lifting the water. Therefore, the suction can be sustained until the pressure of saturated steam becomes equal to the degree of vacuum in the vacuum tank 2. When the degrees  of vacuum thereof are balanced at a predetermine value so as to become the suction  lowered, the mud water is discharged into a mud accumulating tank 3 by closing a vacuum valve B and by opening a vacuum breaking valve D and a discharge valve  C. The separation of the mud from the water is made in the accumulating tank 3, and  the water is returned to a water tank 4. Through the repetitions of the above steps  mud and sand in water can easily be removed.

Filed: 1988-07-07
Abstract: PURPOSE:To obtain an air-tight vibration-proof connection mechanism having both excellent air-tight and vibration-proof qualities at the above device used for an X ray exposure device or the like, by arranging a constitution in which an annular projection of a magnetic body, a non-magnetic member having an annular groove, a magnetic member and a permanent magnet provided on the inside of the groove of the non-magnetic member, are equipped. CONSTITUTION:A magnetic passage is formed at an annular projection 21 and a magnetic member 26 by means of an electromagnet 24, and as a result, a magnetic fluid 22 is gathered at a gap between the tip of the annular projection 21 and the magnetic member 26 and both are short-circuited. As a result, a space between an X ray take out opening and a mask is retained air-tightly against the outside. In this instance, the magnetic fluid 22 being a fluid, it can easily transform against an outer force, so the vibration of a vibration generation portion 10 is not transmitted to a portion 13 which is to be connected with. Accordingly, an air-tight vibration-proof connection mechanism which can make connection with ample air-tight and vibration-proof qualities and also, can be separated simply, can be obtained.

Abstract: PURPOSE:To suppress the growth of the crystal grains of the structure and to improve workability such as cutting by treating a steel sheet in a nonoxidative gaseous atmosphere of the pressure higher than the atm. pressure at the time of subjecting the steel sheet to vapor deposition of Si then to a diffusion treatment. CONSTITUTION:The steel sheet S is introduced into a heating furnace 1 where the steel sheet is subjected to the nonoxidative heating to a prescribed temp.; thereafter, the steel sheet is introduced into a CVD furnace 2. The Si is deposited by evaporation onto the surface of the steel sheet in said furnace at a prescribed temp. in the nonoxidative gaseous atmosphere contg. a prescribed ratio of SiCl4. The steel sheet S is then passed through an atmosphere sepn. chamber 5 and is introduced into a diffusion chamber 3 where the steel sheet S is soaked at the prescribed temp. in the nonoxidative gaseous atmosphere without contg. the SiCl4 to diffuse the Si deposited by evaporation on the surface of the steel sheet into the steel sheet S. The atmosphere control is so executed at the time of such diffusion treatment that the pressure of the nonoxidative gaseous atmosphere of the furnace 3 is kept always higher than the atm. pressure. The crystal grains of the structure is thereby easily suppressed to the smaller grain sizes.
