Abstract: An internal substance supplier includes a conveying mechanism including a conveying member configured to capture and convey an internal substance, and a supply mechanism including a scraping member disposed to cross a conveyance route of the substance by the conveying member in the conveying mechanism and configured to collide with the substance conveyed by the conveying member, a gliding member including a recessed groove configured to guide the substance colliding with the scraping member and scraped from the conveying member, to be adjacent to a position vertically above a die bore in a table in a compression-molding machine, and a push transfer member including a projection configured to come into contact with the substance, push the substance to a start edge of the recessed groove in the gliding member, and move along the recessed groove to transfer the substance to an end edge of the recessed groove.

Abstract: The signal separation device includes: cross product calculation means receiving an input of an observed signal that is a mixture of a plurality of target signals, and calculating a cross product of the observed signal; model calculation means updating a parameter of a model for estimating the cross product with a predetermined algorithm using an inverse matrix of a matrix that represents an estimate of the cross product; inverse matrix calculation means calculating the inverse matrix of a matrix by a SIMD command when the parameter is updated; and separation means calculating the target signals using a matrix representing an estimate of the cross product, the updated parameter, and the observed signal.

Abstract: Provided is an electric pump having an elastic member that is not easily detached, and the housing formation cost is not high. The electric pump includes a pump body with a housing and an elastic member arranged on an outer circumferential surface of the housing. An elastic member arrangement portion is provided on the outer circumferential surface. A protrusion is provided on the elastic member arrangement portion. The protrusion includes a pillar portion and a fastening portion extending from the pillar portion. The fastening portion has a hook part. The elastic member has holes in two opposite ends, and the holes are engaged with the protrusion. The two opposite ends overlap with each.

Abstract: A semiconductor device includes the following elements. A sense amplifier amplifies signal on a bit line. A column switch is between the bit line and a local input-output line. A sub-amplifier amplifies signal on the local input-output line. A write switch is between the local input-output line and a main input-output line. A write amplifier amplifies write data and supplies the amplified write data to the main input-output line when data write operation is performed. A test circuit activates the sense amplifier while the test circuit deactivating the sub-amplifier and the write amplifier when a data read operation is performed in test mode. The test circuit places the column switch and the write switch in conductive state.

Abstract: The method of making a piston unit for an internal combustion engine incorporates the steps of pinching a melting core in a mold cavity of a piston mold wherein the melting core includes an inner ring that forms a ring shaped passage within a piston body, an outer ring and a plurality of coupling portions connected with between the inner ring and the outer ring. The method further includes pouring molten metallic alloy into the cavity and solidifying therein, removing the outer ring of the melting core, filling the space left by removal of the outer ring with reinforced material, and then melting the inner ring and the coupling portions of the melting core.

Abstract: Piston unit used in an internal combustion engine, which allows no interfacial crack between a piston and a wear-proof ring as well as allowing to provide T6 treatment to aluminum base alloy used for the piston. The piston unit has a piston formed of aluminum base alloy, and a wear-proof ring that has been fused with a first ring groove of the piston. The wear-proof ring is formed of copper-zinc alloy with its thermal expansion coefficient ranging from 19.5.times.10.sup.-6 m/m to 22.0.times.10.sup.-6 m/m. The copper zinc alloy may contain 63 wt. % of copper, 30 wt. % of zinc, 15 wt. % of aluminum, and 4% of titanium, or it may contain 70 wt. % of copper and 30% of zinc only.
