    摘要: A method for die-casting a magnesium alloy comprises the step of casting a die cast product free of any hot tearing, shrinkage tearing and shrinkage cavity starting from a magnesium alloy comprising i) 1 to 10% by weight of aluminum; ii) at least one member selected from the group consisting of 0.2 to 5% by weight of a rare earth metal, 0.02 to 5% by weight of calcium and 0.2 to 10% by weight of silicon; and iii) not more than 1.5% by weight of manganese, and the balance of magnesium and inevitable impurities, using a cold chamber type die-casting machine, wherein a) the temperature of the molten magnesium alloy is maintained at 650 to 750°C.; b) the charging velocity of the molten metal is set at {fraction (1/100)} to {fraction (10/100)} second; and c) the intensified pressure after the charging is set at a level of not less than 200 kgf/cm2. Thus, a die cast product free of any hot tearing, shrinkage tearing and shrinkage cavity can be produced by appropriately specifying injection conditions, mold conditions, conditions for melting a magnesium alloy and mold plan in the cold chamber type die-casting machine, or by appropriately controlling the temperature of the molten metal from the molten metal-accommodating pot to the gate portion of the machine.

    摘要: In an embodiment managing a cache includes determining from metadata of a received service request whether a cache data response may satisfy the request as a function of recognizing a cacheable method name specification within request metadata by a service provider associated with the request, the embodiment further including determining whether the request is an inquiry or a request as a function of comparing an update frequency specification in the request metadata to a value of a time parameter associated with the cacheable method name in the metadata if the request may be satisfied by the cached data. The embodiment also includes searching the cache for the data response if determined the data is cacheable and the request is an inquiry, and sending the request on to a service provider if the data response is not a cacheable response or the request is an update request.

    摘要: In a printing press abnormal state display method, the current states of a plurality of elements of a printing press are detected. The detected current state of each element is compared with a normal state predetermined for the element. It is determined on the basis of the comparison result whether the current state of the element is abnormal. The abnormal state of only an element determined to be abnormal is displayed on the basis of the determination result. A printing press abnormal state display apparatus is also disclosed.

    摘要: A soil activator which contains soluble state calcium and magnesium. The soluble state calcium is easily absorbed into plants in the soil and easily moves inside the plants after being absorbed. The soil activator is made by heating and stirring a soil activator composition containing food waste, dolomite, and quicklime. Agricultural crops obtained using the soil activator have significantly increased calcium content.
