Abstract: A device for removing sand from a work by vibration which vibrates a molding (work) molded by casting such as an auto part to thereby remove core sand remaining on a hollow portion of the work and in which the work is held against a vibration plate and the vibration plate is vibrated with a single vibration motor to remove the sand. The device for removing sand from a work 1 by vibration which removes sand remaining on the work 1 by vibration, the device comprising a base 3, a vibration plate 5 mounted on the base 3 via elastic support members 4, a work holder 6 provided on the vibration plate 5, and a vibration motor 7 connected to the vibration plate; wherein the work is held with the holder 6, and the vibration motor 7 is then actuated to vibrate the vibration plate 5, thereby applying vibration to the work 1 held with the holder 6 to remove the sand from the work 1.

Abstract: The drink liquid, such as beer, soft drink, etc., stayed in stay portion 5 of filler during the filling operation is recovered without dropping of the quality. The filler is composed of cylinder rod 4 connected to the cap 3 of container 2, discharge hole 7 longitudinally penetrated through a center of the cylinder rod 4, a stay portion 5 secured at the upper part of the periphery of cylinder rod 4, through which the drink liquid passes, and a supply pipe 6 for drink liquid connected to the stay portion 5, and characterized in that the storage equipment 12 for stayed liquid having storage room 18 is secured on supply pipe 6, and pipe 11 for introducing pressurized air is also secured. It is connected to stay portion 5 through discharge hole 7.

Abstract: An apparatus A for cutting off an unnecessary object deposited on a casting includes a motor having a rotary shaft 3 adapted to be rotated at a high speed, and a disk-shaped diamond tip saw 2 mounted at a tip end 4 of the rotary shaft 3 and adapted to be rotated by the rotation of the rotary shaft 3 to cut off the unnecessary object 9 on the casting 8, so that the tip saw 2 is rotated at a rotational speed in a range of 6,000 rpm to 8,000 rpm. Thus, the rigidity of the diamond tip saw 2 rotated at the high speed is increased by a centrifugal force provided by the diamond tip saw 2 itself and a gyroscopic moment effect to reduce the thickness of the diamond tip saw 2 can be reduced by a value corresponding to an increment in rigidity of the tip saw 2, whereby the amount of diamond tips (diamond blades) used can be decreased; an energy-saving for a cutting power can be achieved, and the amount of chips produced upon the cutting of the unnecessary object can be reduced.
