Abstract: An end structure for a shielding wire is provided with a covering part 20 for covering an end portion 18b of a braided wire 18. In arrangement, an end 19a of an outside insulating rind 19 is positioned so as to recede from an end 18a of the braided wire 18. The covering part 20 is welded to an inside insulating rind 17 in the vicinity of the end portion 18b of the braided wire 18. Owing to the provision of the covering part 20, it is possible to prevent the braided wire 18 from being loosen from the end portion 18b.

Abstract: A duplex heat exchanger of the so-called stacked type has in principle a plurality of plate-shaped tubular elements (1) which are stacked side by side or one on another and a plurality of fins (2) each intervening between the adjacent tubular elements. Each tubular element is composed of flat tubular segments (3a, 4a) separated from each other and each communicating with one of bulged header portions (3b, 4b) of the tubular element, so that flow paths (3, 4) for heat exchanging media are formed through each tubular element. Two or more unit heat exchangers (X, Y) are defined integral with each other within the duplex heat exchanger, since the adjacent tubular elements (1) communicate with each other through the header portions (3b, 4b).

Abstract: The present invention provides a molding sheet material having a sandwich structure produced by preparing a fiber reinforced thermoplastic resin layer (A) reinforced with a woven fabric or a knitted web and a fiber reinforced thermoplastic resin layer (B) reinforced with a random mat and using the layer (A) as a core layer and the layer (B) as a skin layer, or using the layer (B) as a core layer and the layer (A) as a skin layer. When this sheet material is molded into a three-dimensional structure, the layer (B) serves as a cushion to prevent the occurrence of a wrinkle or a crease in the layer (A). A toe puff for a safety shoe having a light weight and excellent pressing resistance can be prepared through the molding of this sheet material. In the sheet materials, the core layer or the skin layer consisting of a thermoplastic resin reinforced with a woven fabric or a knitted web of a reinforcing fiber may be prepared from a woven fabric or a knitted web of a reinforcing fiber alone.

Abstract: A method is provided for manufacturing a master slice semiconductor integrated circuit device. Initially, a first total circuit diagram which is to be reformed into a master slice semiconductor integrated circuit device is defined. First and second circuit points on the first total circuit block which are to be used respectively as input and output terminals of the master slice semiconductor integrated circuit device are specified. Next, signal transmitting paths are successively traced from the output to the input of each logic gate located in the signal transmitting paths in actual use. In the course of the tracing, these traced gates are marked and the logic gates actually in use are identified. As a result, in addition to those logic gates having unused output terminals, the gates constituting a closed loop isolated from the signal transmitting paths for transmitting substantial output signals are identified as unnecessary gates and deleted.
