Abstract: Disclosed is an electromagnetic coupling designed to strengthen the magnetic force exerted from an electromagnetic coil in the direction in which a pilot clutch is operated. In the electromagnetic coupling with the pilot clutch for activating a main clutch wherein clutch plates are thrust with a retaining ring moved by magnetic force produced by an electromagnetic coil in the pilot clutch, the electromagnetic coil in the pilot clutch is surrounded with ferromagnetic material over at least two of its three facial sides other than its magnetic force exerting facial side, namely over at least its rear and outer facial sides and the ferromagnetic material is covered with nonmagnetic material.

Abstract: A method whereby magnetic and nonmagnetic materials can be joined together firmly and having their joining areas freed from embrittlement and with a minimum of deformation is disclosed. Applied to the process of fitting a ring of nonmagnetic material into an annular space formed between an inner and an outer member each made of magnetic material, the method includes bringing an inner and an outer peripheral surface of the ring of nonmagnetic material each into a semi-molten state and bringing the inner and outer peripheral surfaces of the ring of nonmagnetic material into pressure contact with the inner and outer members, respectively, to join the inner and outer peripheral surfaces to the inner and outer members, respectively, by interfacial fusion.

Abstract: A transmission apparatus unitizes a plurality of variable-length frames in units of predetermined size and sorts the unitized frames for each unit into each of a plurality of ports, thereby transmitting the sorted frames. A reception apparatus accumulates received frames in each port and collects the accumulated frames for each unit from each port.

Abstract: A roll forming method is used for forming an annular product with a radially outwardly extending flange portion at an end and includes steps of holding a center portion of a work for forming the annular product by a holding device, rotating the work, contacting a circumferential end portion of the rotating work with a forming roller to be pressed to form the flange portion while retaining a circumferential outer end of the work. The present invention is advantageous in that the resultant product has a good quality without deficiency, such as underfill of the material and has an improved toughness unlike a cast product, a product made by welding and the like of the same structure.

Abstract: A headphone includes a headband, at least one headphone unit, a belt-like member and a wind-in mechanism. The headband is made from an elastically deformable material and is of an inverted U-shape. At least one headphone unit is mounted at one of the ends of the headband. When the headphone is fit onto the head a belt-like member is drawn out of the wind-in mechanism and assumes a shape that follows the shape of the head. The belt-like member is mounted in such a way that it stretches between the two ends of the headband. The wind-in mechanism automatically winds in the drawn-out belt-like member. The wind-in mechanism is mounted at a part of the headphone where one end of the belt-like member, one end of the headband and a headphone unit are joined.

Abstract: A vibration-damping composite sheet steel made by sandwiching a viscoelastic material between two steel sheets. A rust proofing coating which generates no gaseous matter is formed on one surface of each of the steel sheets which is contacted with the viscoelastic material. The coating is a phosphate coating having no water of crystallization with a coating weight per unit area of 0.5 g/m.sup.2 or over, or a galvanized zinc coating including no zinc oxide.

Abstract: A headphone device includes a pair of housings each attached to a hanger and supporting a loudspeaker unit, and a headband having opposite ends to which the hangers are secured. Each housing includes a front plate to which the loudspeaker unit is attached and a main body portion preferably constructed of natural wood and enclosing the loudspeaker unit with the exception of a front surface of the loudspeaker unit. The inner surface of the main body portion of the housing includes a plurality of irregularities which prevent the generation of standing waves and scatter the housing resonant locations so as to maintain a high quality of reproduced sound.
