Abstract: A resin-sealed module is provided which reduces the warpage of a substrate and the detachment between a sealing resin and the substrate which occur during re-reflow, has the excellent flatness of the top and bottom surfaces, and reduces the occurrence of the short failures. A resin layer made of a thermoplastic resin is arranged on top of a substrate, and a resin layer made of a thermosetting resin is arranged on top of this resin layer, thereby reducing the warpage of the substrate and the detachment between the sealing resin and the substrate which occur during re-reflow.

Abstract: An electronic component and a method of manufacturing an electronic component including a first surface mount device and a second surface mount device are provided. The first surface mount device and the second surface mount device are joined to a substrate via joint materials such that either or both of the first and second surface mount devices are shifted from the locations corresponding to land electrodes located on the substrate so as to be aligned with each other and are subjected to a reflow process. The outer land electrodes are formed at locations shifted inwardly from the locations corresponding to a virtual arrangement state in which the first surface mount device and the second surface mount device are arranged in series such that an end surface of the first surface mount device is in contact with an end surface of the second surface mount device.

Abstract: A streaming image distribution system which can distribute streaming images to many and unspecified viewers as well as specified viewers. The streaming image distribution system includes a distribution management server having distribution management data containing, through registration, channel numbers set for respective requesters requesting distribution of the streaming images, file names related to the streaming images to be distributed for respective channel numbers, identification codes, image distribution periods, addresses of the image distribution servers storing the streaming images provided with the respective filenames. Reception terminal apparatuses for users to enjoy streaming images, when requesting the distribution of streaming images, transmits the channel numbers and image identification codes to the distribution management server.

Abstract: The present invention provides a method for manufacturing a highly reliable electronic component in which the shield case is securely fixed to a substrate without requiring a step for filling a solder paste in engaging holes, and a highly reliable electronic component with a shield case manufactured by the method, wherein engaging pins of the shield case are inserted into the engaging holes of the mother substrate, reflow soldering is applied when the solder paste is coated on the circumference of the engaging holes as well as on the area including the circumference of the engaging hole and at least a part of the engaging hole at the reversed face (back face) of the component mounting face covered with the shield case of the mother substrate, and mother substrate is divided into individual electronic component with the shield case after soldering the engaging pins of the shield case to the case fixing electrodes disposed on the circumference face of the engaging holes.

Abstract: A wire rope for a heavy-load crane, such as a ladle crane is provided that is not only almost rotation-resistant but is also unlikely to be broken by wear and fatigue of wires. The rotation-resisting wire rope has a plurality of side strands. In side each strand, wires are laid in the same direction as the lay of core strand wires, around the periphery of a core strand. The side strands are laid in a direction opposite to the lay of the core strand wires so as to form the wire rope. The side strands preferably have a smaller pitch multiple than a pitch multiple of the wire rope. The ratio between a diameter of the side strands and a diameter of the core strand is preferably about 1.3 to about 1.8. The pitch multiple of strands is preferably about 5 to about 8 and the pitch multiple of the wire rope is preferably about 8 to about 10. Both the core strand and the side strands preferably have shaped wires, having a flattened surface, at an outermost ply.

Abstract: A tension device for winding yarn includes a bracket with an inclined face and a braking member accommodated in the bracket. A rotary shaft protrudes from the center of the bracket. A tubular member has a through-hole for the rotary shaft. A forward guide member includes two hub members mounted on the axial end of the rotary shaft with a yarn winding portion joining the hub members.

Abstract: A compact, inexpensive electromagnetic spring clutch includes forming supporting bearing surfaces made of synthetic resin rotary members, in a magnetic excitor. Cylindrical magnetic pole parts are formed in the first core and second core and the inner surfaces of these magnetic pole parts are made into bearing surfaces.

Abstract: An electromagnetic steel sheet has an electrically insulating coating with superior weldability, formed by coating a treatment solution on the electromagnetic steel sheet and baking the same, the treatment solution containing a synthetic resin fine-particle emulsion having resistance against chromic and/or bichromic acid and exhibiting a peak temperature not lower than 400.degree. C. at which a weight change rate is maximized when a sample is heated at a constant rate in differential thermal gravimetry, a chromate and/or bichromate base aqueous solution containing at least one kind of two-valence metal, and an organic reducer. The steel sheet is superior in electrical insulation, adhesion, punching ability, weldability and corrosion resistance.

Abstract: An axially displaceable brake element is arranged in facing relation to an operating element which is pivotable through a predetermined circumferential angle, with clutch balls engaged in grooves having slanted bottoms and formed in mutually facing side surfaces of the brake element and the operating element. Pivoting of the operating element causes displacement of the brake element relative to the operating element. A friction plate is spline-fitted on an output hub so as to be displaced only in the axial directions and arranged selectively for frictional contact with the brake element or the operating element. Displacement of the brake element toward the operating element causes frictional engagement of the friction plate with an input hub to obtain engagement of the clutch, while displacement of the brake element away from the operating element causes frictional engagement of the friction plate with the brake element to obtain disengagement of the clutch and braking of the output hub.

Abstract: A highly adhesive and uniform insulating film can be formed on a grain-oriented silicon steel sheet without deteriorating the iron loss of the steel sheet by the use of a magnesia series annealing separator containing a strontium compound.

Abstract: A highly adhesive and uniform insulating glass film can be formed on surfaces of an oriented silicon steel sheet by pickling a finally cold rolled silicon steel strip just before a decarburizing annealing, and successively subjecting the pickled steel strip to the decarburizing annealing, an application of an annealing separator and a final annealing at a high temperature.

Abstract: An insulating glass film having an excellent uniformity and a high adhesion to a grain-oriented silicon steel sheet having a high magnetic induction is formed by annealing a coil of a cold rolled silicon steel sheet having a final gauge in an annealing furnace under a non-oxidizing and non-reducing neutral inert gas, such as nitrogen or argon at a constant temperature keeping stage of 800.degree.-920.degree.C and then under dry hydrogen at a temperature of 1,000.degree.-1,200.degree.C in the final annealing stage.
