Abstract: A seal structure for a gas turbine blade including a shank including a first side surface, a second side surface, and a bottom surface located radially inward from a fin. The first side surface has a recess movably housing a wedge seal, and a slot on the bottom surface as an insertion opening for a spline seal. The second side surface has a slot on the bottom surface as the insertion opening. The recess has an inclined surface extending straight radially inward and away from the first side surface. The wedge seal includes a wedge portion including a first wedge surface to be opposed to the inclined surface and a second wedge surface to be opposed to the second side surface of the adjacent rotor blade to form a wedge together with the wedge surface, and a weight portion positioned radially inward in the recess from the wedge portion.

Abstract: A guiding surface expanding to the outer circumferential side from the upstream side toward the downstream side is formed on the support section, a guided surface expanding to the outer circumferential side from the upstream side toward the downstream side is formed at an end portion on the outer circumferential side of the shielding member, and the shielding member covers a gap between the disc and the turbine blade in the fitting section in a state in which the guided surface abuts against the guiding surface at least when the disc is rotationally driven.

Abstract: There is provided a system or others capable of predicting a parts shipment quantity varying in accordance with an assumed parts-purchase period (such as a charge-free warranty period of a product) (having a period length with taking a product shipping date as a starting point during which a customer is assumed to purchase parts) so that prediction accuracy can be increased more than a conventional one. In the prediction system (1) for the parts shipment quantity, a server (10) has a prediction unit (100) to which product data (D1), parts shipment data (D2), and a prediction condition (D3) containing information of the assumed parts-purchase period are inputted and which performs a process of predicting a future shipment quantity for each parts and of outputting prediction result data (D0). The prediction unit (100) performs a process of predicting the future shipment quantity for each parts in accordance with the assumed parts-purchase period.

Abstract: A shipping instruction determination system provides a storage device which stores a shipping request in a supply destination, a supply available schedule of a supply source, information of a packaging form indicating a combination of products and its number of units to be able to be packed in packaging boxes to be used for a shipment and a physical distribution cost for every packaging form, and a shipping instruction calculation unit which calculates a combination, a physical distribution cost of which becomes minimum, of a shipping date, the number of shipping units and a packaging form from among the shipping available combinations of the shipping date, the number of shipments and the packaging form, from the shipping request, the supply available schedule, the information of packaging form and the physical distribution cost for every packaging form to determine a shipping instruction.

Abstract: A transportation schedule planning support system receives an order of one or more types of products which requires a use-by date control, and transports the products from one or more stock-carrying bases to one or more delivery destinations. In the system, a user previously registers a transportation route candidate from a stock-carrying base to each delivery destination adoptable as a solution, as a base group. A necessary use-by date for a product to be delivered next is determined based on an actual delivery to each delivery destination. The number of vehicles allocatable to a transportation at each base according to a vehicle type, and a vehicle type not used in each base group are added to a restriction condition. A mixed integer programming is applied using an expected obtainable profit obtained by delivering each product as an objective function.

Abstract: Embodiments of the present invention provide a production planning method and system. Where a manufacturing apparatus is shared by a plurality of products in a production line, if a manufacturing (production) availability number is changed, a cause parameter is automatically investigated so that a production plan with high precision can be prepared in a short time. With respect to a production plan as the previous/current comparison objects, a production process used in the production plan in which a change occurs, is extracted. From the production process, a parameter item to be used in the production capacity evaluation is extracted for all products, a difference comparison is made between the value of the previous parameter and the value of the current parameter, so that the parameter item as the cause is specified. The combination of the cause parameter items is calculated, and a cause parameter list is prepared.

Abstract: A system and method for generating disassembly, procurement and production plans dealing with recyclable parts and products are provided. Production demand information on products to be manufactured, collection schedule information on individual used products and recyclable part table on recyclable parts contained in the used products are stored in memory; recyclable part availability information is generated by referring to the collection schedule information and the recyclable part table; and by referring to the production demand information and the recyclable part availability information, a disassembly plan on the recyclable parts is created based on the production demand. Further, the production demand information and the recyclable part availability information are referenced to generate a procurement plan on parts and materials that cannot be fully supplied from available, recyclable parts alone. Based on the disassembly and procurement plans, a production plan is created.

Abstract: A membrane filter of 0.025 to 0.05 .mu. in pore size is treated by passing the solution of a water-soluble high molecular substance such as albumin, dextran, polyvinylpyrrolidone, polysorbate 80, gelatin or the like through the membrane filter. Employing the filter thus treated, the solution of a physiologically active substance of human origin such as human growth hormone, kallikrein, trypsin inhibitor, epidermal growth factor, leucocyte interferon etc. is filtered at high recovery rate of the active substance avoiding the adsorption of the active substance onto the filter. By the filtration, harmful viruses such as Creutzfeldt-Jacob disease pathogen which may exist in the physiologically active substance can be removed.
