    摘要: A method of and a system for operating a squeeze plunger in a die cast machine. When the fill-up of molten metal in a cavity is completed by an injection plunger, the moving speed of the injection plunger is rapidly decreased. When the speed at this time becomes lower than a preset value, a preset delay time is measured. After a lapse of this delay time, the squeeze plunger is operated to press a molding material in the cavity, so that plastic flows are caused in the molding material.

    摘要: This invention relates to a casting control system of a die cast machine, and more particularly to a system for controlling a high speed injection real stroke of an injection plunger and controlling valve closing timing for degassing gas in a mold cavity. The high speed injection real stroke is measured by an arithmetic unit from a signal output from a position detector, and the high speed injection real stroke is then compared with a certain preset value. When arithmetic unit determines that the high speed injection real stroke and the preset value do not coincide with each other, a pretest action delay time of the injection plunger is .+-. incrementally or decrementally corrected until both values coincide. The arithmetic unit determines a start position of the high speed injection real stroke, outputs a signal to close a breathing valve at a position, to which is added or from which is subtracted a predetermined variable value with respect to the real start position and outputs a signal to open the breathing valve at a position where the injection plunger closes a molten metal feeding port.

    摘要: A stroke-end position of an injection cylinder of the die cast machine is detected and a position of the injection cylinder for sending a boosting-signal is set. This position is a predetermined standard boost stroke distance from the stroke-end position. When the injection cylinder reaches the position for sending the boosting-signal in the casting cycle, an oil-pressure intensifier is advanced. In this method, before casting is performed, a value representing a stroke after slowing-down and a setting value of the plunger stopping position are determined and the start point for slowing-down is calculated by subtracting the value of the stroke after slowing down from the setting value.

    摘要: The present invention relates to a novel two cyclic cinnamide compound and a pharmaceutical agent comprising the compound as an active ingredient. The two cyclic cinnamide compound represented by the general formula (I): wherein represents a single bond or a double bond; Ar1 represents a phenyl group or pyridinyl group that may be substituted with 1 to 3 substituents; R1 and R2 each represent a C1-6 alkyl group, a hydroxyl group, or the like; Z1 represents a methylene group or vinylene group, which may be substituted with 1 or 2 substituents selected from Substituent Group A1, an oxygen atom, or an imino group that may be substituted with a substituent selected from Substituent Group A1; and p, q, and r each represent an integer of 0 to 2, which has an effect of reducing Aβ40 and Aβ42 production, and thus is particularly useful as a prophylactic or therapeutic agent for a neurodegenerative disease caused by Aβ such as Alzheimer's disease or Down's syndrome.
