    摘要: A capacitance type acceleration sensor includes a semiconductor substrate, a weight portion supported with the substrate through a spring portion, a movable electrode integrated with the weight portion, and a fixed electrode cantilevered with the substrate. The movable electrode is displaced along with a facing surface of the movable electrode in accordance with acceleration. The facing surface of the movable electrode faces a facing surface of the fixed electrode so as to provide a capacitor. The capacitance of the capacitor changes in accordance with a displacement of the movable electrode so that an outer circuit detects the acceleration as a capacitance change. Each facing surface of the movable and fixed electrodes has a concavity and convexity portion for increasing the capacitance change.

    摘要: A high pressure die casting method including providing first and second accumulator assemblies, wherein the first accumulator assembly provides pressurized fluid toad die assembly while the second accumulator assembly provides pressurized fluid to remaining portions of the die casting machine. A barrel insert loader inserts cylinder barrels into the die assembly, and then the dies are closed to permit molten aluminum to be injected therein and thereby form the cast engine block. The dies include side gates and sub-gates through which molten aluminum is introduced into the mold. The dies are opened, and the cast engine is removed from the dies by operation of a robot arm, and a die spraying assembly is inserted between the open dies and sequentially sprays the dies, to clean and cool the dies in preparation for a subsequent casting operation.

    摘要: For continuous production of a resin film having a plain surface, a resin solution cast in film form over an endless belt is pre-hardened by a gas stream supplied for flow in a direction generally parallel to the surface of the endless belt, and then a jet of gas is blown in the direction of movement of the endless belt whereby the resin is hardened. In the process for resin film production wherein the resin film is cast over the endless belt and then pre-hardened by a parallel gas stream, the cast film being then hardened by a jet of gas, the installation for production is divided by partitions so as to enable various stages to be operated independently.

    摘要: Disclosed is a continuous two-liquid type mixer comprising:a cylindrical container having an liquid inlet at one end and an outlet at the other end;rows of stationary stirring blades on the inside of said cylindrical container protruding substantially radially on the same periphery;a rotor to rotate about the same axis and housed in said cylindrical container; androws of rotary stirring blades on the outside of said rotor protruding substantially radically on the same periphery in an alternate relation with said rows of stationary stirring blades on the inside of said cylindrical container, wherein at least one liquid injection inlet is provided on either or both of said stirring blades on said liquid inlet side. According to the present invention, even highly viscous liquids can be mixed quickly and uniformly and troubles caused by ununiform mixing can be solved without fail.
