Title: Sprinkling method and device for mixed powder for water absorption sheet
Inventor: MITA KOZO
IPC: B65D81/26
Filed: 1989-05-18
Abstract: PURPOSE:To sprinkle a mixed powder evenly, and at the same time, to enable a complete automation of a sprinkling mechanism possible by a method wherein the sprinkling quantity of a mixed powder is appropriately and accurately adjusted by changing the peripheral speed of a roller with grooves to the carrying speed of a basic material by a first carrying conveyor. CONSTITUTION:A water absorption sheet is formed into a laminated body for which a mixed powder 16, which is composed of an absorbent resin 13, functional powder 14 and binding agent 15, is sprinkled between a basic material 1 and basic material 2. A sprinkling mechanism has an upside-down trapezoid shaped container 41, and the lower side of the container is closed by a roller with grooves 42. By the rotation of the roller with grooves 42, only the powder in the grooves 43 is discharged outside. At this time, a claw 44 rakes off excessive powder on the groove, therefore, the quantity of the powder to be discharged is always fixed. As a sprinkling quality of an absorbent resin per 1m<2> of sheet, it is desirable to be within a range of 0.1-200g, and the sprinkling quantity is adjusted by changing the peripheral speed of the roller with grooves at random.

IPC: B29C33/38
Filed: 1994-05-12
Abstract: PURPOSE:To facilitate machining without needing to consider shifts by positioning a reference surface part to the boundary surface of a cope and a drag at the time of machining a cast product. CONSTITUTION:A cavity C is formed with the cope 2a and the drag 2b of a mold 1. A recessed part 2a' is formed by using a pattern for upper form of an upper surface core 3 and an upper part core 4 on the lower surface of the cope 2a. A recessed part 2b' is formed by using a pattern on the upper surface of the drag 2b. Molten metal is poured into the cavity C formed in the mold 1 to produce a housing H being the cast product. Then, the cavity C is molded so as to position the part to be the reference surface at the time of machining the cast product produced by pouring the molten metal therein to the boundary surface of the cope 2a and the drag 2b. By this method, the shifts (a) do not emerge on the outer shape of the cast product, thus improving the outward appearance.

Title: Co2 supply method in co2 arc welding device
Inventor: UMEKI YOUKOU
IPC: B23K9/16
Filed: 1978-10-05
Abstract: PURPOSE: To prevent the production of dry ice and supply CO 2  to torch by reducing the pressure of the CO 2  in a vessel to the critical pressure or over with a pressure reducing regulator and leading the same with the hose which also serves as a heat exchanger and conduit then reducing the pressure down to the critical pressure or under.  
     CONSTITUTION: At the time when the CO 2  gas in a vessel 1 is reduced of pressure by the reducing regulator 2 mounted to the vessel 1, its temperature lowers considerably owing to Joule-Thomson effect. This produces a large temperature difference between the atmospheric air of the outside of the hose 3 and the CO 2  of its inside and the quantity of heat that the atmospheric air has flows into the CO 2 , thereby increasing the enthalpy of the CO 2 . Because of this, the hose 3 is made sufficiently long to lead the CO 2  whose temperature has become equal to the atmospheric temperature to a welding power source box 4 or the like. Its pressure is then regulated to the pressure suited for welding in a throttle part 6, tnence it is supplied to a torch 8. Then, even if it is reduced of pressure down to the critical pressure or under where the gas phase and solid phase of the case when the enthalpy is small coexist in the throttle part 6, the production of dry ice is obviated.
