Title: Ice heat accumulating device and heat accumulating method of ice
Inventor: ITO SHINGO
IPC: F24F5/00
Filed: 1990-08-11
Abstract: PURPOSE:To prevent ice, reserved in a heat accumulating tank, from being introduced into a water sucking means and an ice making means by reserving non cold- accumulating material, whose specific gravity is set at an intermediate value between the cold heat accumulating material and the ice, in the heat accumulating tank. CONSTITUTION:When water-soluble liquid W, flowing through a water sucking pipe 3a, has arrived at an ice making tube 4c, the liquid is cooled in a cooling pipe 4b and becomes overcooled condition. Thereafter, when the liquid W is dropped and supplied into a heat accumulating tank 2 from the downstream end of the ice making tube 4c, the overcooled condition of the same is eliminated by the force of shock due to dropping and is changed into ice, then, is reserved in the heat accumulating tank 2 as heat accumulating medium. The produced ice I is separated from the water- soluble liquid W by oily liquid O and is precluded from being mixed with the layer of the water-soluble liquid whereby the ice I will never be introduced into the water sucking pipe 3a. Accordingly, the inflow of the ice I into the ice making means 4 and the elimination of the overcooled condition in the part are precluded whereby a predetermined ice making operation can be effected and the clogging of the water sucking pipe 3a and the ice making tube 4c by the ice I can be prevented.

Abstract: PURPOSE:To contrive an improvement of accuracy of dimensions by eliminating deflection of a grinding wheel by a device which presses a pair of slidable dressing sticks against both sides of the grinding wheel for grinding, by measuring the deflection of the sides of the grinding wheel by a gap sensor after setting of a thin blade grinding wheel on a machine. CONSTITUTION:As for truing of a grinding wheel, a deflection of a circumference of the grinding wheel is trued and at the same time a contact face between sticks 8 and a grinding wheel is formed by securing traveling stands 13 and 14 on a base 10 so as to make the dressing sticks 8 touch each other and a contact part of the sticks 8 is cut off over supply of water on the contact part. When the deflection of the grinding wheel is large this cutting off is repeated. Then, the base 10 is set so that the sticks 8 touch the sides of the grinding wheel, and the traveling stands are made to move freely by removing fixing bolts 15 and 16 of the traveling stands. Simultaneously with the truing of the side of the grinding wheel to be done by rotating the grinding wheel at low speed over supply of cooling water under this condition, the deflection of the grinding wheel is measured by a gap sensor 9 and the truing is kept continued until the deflection of the grinding wheel comes to a fixed value.

Abstract: PURPOSE:To reduce man-hours by attaching a tape obtained by applying or attaching bonding agent on a hard plastic film to the element forming surface of wafer, cutting the film with a press and thereafter grinding the rear side of wafer while the film is attached to a base. CONSTITUTION:A bonding resin 52 is applied or attached to a hard film 5 and the film is wound like a roll through a release paper 25. The element forming surface of wafer 13 is set in the tape side and is held between the release papers 25 and these are pressed by the roller. The wafer is punched in the size just suitable for grinding, the film is set in the side of base 24, it is then attracted, and the wafer is ground up to the specified thickness with a blade 31. According to this method, the wafer can be punched automatically to the optimum size since the film is hard. Moreover, if crack or missing is generated on the wafer, the porous layer 23 at the center of grinding base is not exposed, it is attracted perfectly. When a small size wafer is previously cut in accordance with a large size wafer, it can be ground and base replacement is not required. With such constitution, man-hours for cutting can be reduced.
