Abstract: Provided is a composition for improving liver function that utilizes a plant-derived resorcinolic lipid, being useful, for example, in improving symptoms of non-alcoholic hepatitis. A plant-derived resorcinolic lipid is used as an active ingredient of the composition for improving liver function. The resorcinolic lipid is preferably an alkylresorcinol and is also preferably derived from a gramineae plant, also preferably from wheat and/or rye bran and/or whole grains. This composition for improving liver function is especially suitably used to improve symptoms of non-alcoholic hepatitis.

Abstract: To provide a portal-shaped tear processing device which is capable of stably performing high precision tear processing. Provided is a portal-shaped tear processing device including: a portal-shaped frame; a rail member; a controlled movement robot; and a tear processing means, in which the column member and the beam member have an outer shell portion, a filling member enclosed in the outer shell portion, and a hollow portion boring the filling portion along a major axis direction of the column member and the beam member.

Abstract: A cutting tool for machining a soft material is characterized by, on a substrate, a formation of an upward projecting protruding portion having a cutting blade ridge and a formation of an upward projecting pressing portion having a lower height than the protruding portion. The pressing portion adjoins at least the front side of the protruding portion in the rotational direction T (front side in the work material cutting direction). This cutting tool for machining a soft material may improve machining efficiency when conditioning the surface of a pad.

Abstract: An apparatus for generating a high speed dubbing signal to be recorded by an external recording apparatus. The high speed dubbing signal, whose pitch is N times that of a digital input signal, is generated as follows. An encoding circuit subsamples the digital input signal consisting of frame signals each of which consists of N field signals, so that each frame signal is compressed by a factor of N to be contained in one field interval. A digital signal recording and reproducing circuit including a recording and reproduction system, records on a tape, at a normal tape speed and at a normal head drum rotational frequency, the compressed signal in such a manner that each field including the compressed signal appears once per frame interval, and then selectively reproduces from the tape the field including the compressed signal at a tape speed N times the normal speed and at the normal drum speed.

Abstract: A copper foil for printed circuits has a roughened layer formed on the side of the foil to be bonded to a base, the roughened layer consisting of a number of protuberant copper electrodeposits containing chromium tungsten or both. It may also have a copper plating layer covering the roughened layer and a treatment layer covering the copper plating layer and formed of either a metal selected from the group consisting of copper, chromium, nickel, iron, cobalt, and zinc, or an alloy of two or more such metals. When necessary, the copper foil may contain an anticorrosive layer including various chromate treated layers further formed on the treatment layer. The copper foil is produced by electrolyzing a raw foil as a cathode in an acidic copper electrolytic bath at a current density close to the critical density, thereby forming the roughened layer, the electrolytic bath containing 0.001-5 g/l of chromium ion tungsten ion or both.
