Further, an engine (13) is placed at a position fronting to between the left and right supporting column portions.

Abstract: A rear end small revolving type hydraulic shovel (tight tail revolving hydraulic excavator) that can improve maintainability of an engine and secures a wide foot space of an operator's cab is provided. In order to achieve this, the engine (13) is arranged below an operator's seat (21). Additionally, a floor frame (30) supporting the operator's seat (21) defines a front partition wall (33b) and an upper partition wall (33a) of the engine. Further, the floor frame (30) is configured so as to be tilt-up. Furthermore, a piping (42) and a wiring (46) connected to an equipment (41) on the floor frame (30) side are arranged so as to pass through the vicinity of an axis line of a tilt-up supporting point.

Abstract: The invention provides a working machine of a hydraulic backhoe in which the blade tip force can be increased over a wide range of operations, which has a great blade tip force at the start of excavation, and which can increase working efficiency by avoiding obstacles. For these purposes, a second link pivotally connected to third fulcrums (6, 13) provided in common at a leading end of an arm cylinder (4) and one end of a first link (10) and to a second fulcrum (12) of an arm (2) is a hydraulic correction cylinder (11). A working hydraulic circuit for the arm cylinder (4) and the correction cylinder (11) may constitute a series circuit having a circuit (24) connecting a head side oil chamber (20) of the arm cylinder (4) to a bottom side oil chamber (23) of the correction cylinder (11).

Abstract: A coating agent for delaying the release of a physiologically active substance to be administered per os to ruminants, said coating comprising a veterinary acceptable water-soluble, synthetic high molecular compound and ethylcellulose, said coating agent being stable in the first stomach or rumen of ruminants and capable of being effectively disintegrated for subsequent absorption in the 4th stomach of ruminants, characterized in that said coating agent further comprises at least one substance which is miscible with both of said high molecular weight compound and ethylcellulose and is insoluble in water.Said coating agent forms a coat which protects the active substance from degradation in the first stomach of a ruminant at a pH of about 5.5 and rapidly breaks down in the 4th stomach at a pH of about 3, thereby releasing the active ingredient for absorption by the animal.The coating agent and the actives coated therewith and their preparation are described.

Abstract: A method of stabilizing the activity of an extract of the New Zealand green lipped mussel (Perna canaliculus) includes adding at least one organic acid or an alkali metal or alkaline earth metal salt thereof to the extract. Preferred organic acids are organic aliphatic acids having from 1 to 10 carbon atoms, particularly tartaric acid. Also disclosed is a food supplement and/or pharmaceutical preparation which includes the stabilized extract.

Abstract: A machine tool is disclosed as exemplified by a drilling machine for creating holes in printed circuit board blanks, comprising one or more toolheads each releasably holding a drill for working on the blanks on a table, the latter being movable horizontally to and away from a preassigned tool change position. The table has mounted thereon a row of old tool pots each for temporarily holding a worn drill released from one of the toolheads, prior to discharge to a recovery mechanism under the table, and a row of new tool pots each for temporarily holding a new drill to be held by one of the toolheads in substitution for the old drill released therefrom in the associated old tool pot.

Abstract: A machine well suited for the creation holes in printed circuit boards (PCBs). A work supply magazine containing a stack of PCBs to be drilled is disposed on one side of the machine, and a work recovery magazine for receiving the drilled PCBs is disposed on the other side, with a table mounted therebetween, preferably for displacement in one horizontal direction. One or more saddles, each carrying one or more toolheads and driven by a common saddle motor, are disposed over the table for reciprocating movement in a direction at right angles with the direction of table displacement. Also disposed over the table and reciprocably movable in the same direction as the saddles is a carriage carrying a set of work transfer fingers movable up and down into and out of work transfer engagement with the PCBs in the work supply magazine and on the table. The saddles and the carriage can be connected and disconnected as required.

Abstract: The rate of solubility of a material of low solubility is increased by mixing the material with beta-1, 4-glucan and pulverizing the mixture. This simultaneously pulverizing both ingredients is found to produce a substantially different effect than when the ingredients are separately pulverized and then mixed together.
