Abstract: A DSL communication method is used for interconnecting a user and a center by using a 2-wire telephone line and a DSL communications technology so that the user and the center perform an intercommunication. The DSL communication method comprises the step of monitoring a signal-to-noise ratio of an accepted DSL, the step of judging whether or not the signal-to-noise ratio is within a predetermined range, and the step of interrupting the intercommunication once and thereafter reconnecting the user and the center, when the signal-to-noise ratio is judged not to be within the predetermined range for a duration longer than a reference time.

Abstract: The present invention is a cooling device, wherein cooling is effected by enclosing a working fluid in a conduit, which is formed by providing a looped tube formed by interconnecting both respective ends of a stack combining a hot heat exchanger with a cold heat exchanger and a stack combining a cooling heat exchanger with a cooling output heat exchanger and by providing at least one or more acoustic wave generators outside or/and inside the looped tube, and then generating a standing wave and traveling wave in the working fluid, with the present cooling device being primarily capable of markedly shortening the time until the start of generation of the standing wave and traveling wave and providing stable control.

Abstract: A positive electrode plate (11) and a negative electrode plate (12) are coiled around into a flat shape such that positive electrode layer faces (22a-22e) and negative electrode layer faces (23a-23f) are alternately layered upon one another with a separator interposed therebetween. Positional discrepancy detecting holes (41a, 41b, 42, 43, 44) are formed in the positive electrode layer faces (22a, 22b) and negative electrode layer face (23a) facing each other at the coiling start end, and in the positive electrode layer face (22e) and negative electrode layer face (23f) facing each other at the coiling finish end. The electrode plates are coiled into an electrode plate group, which is subjected to X-ray inspection for detecting positional displacement based on a discrepancy in the positions of the holes.

Abstract: A commutator motor includes a stator and a rotor, and the stator includes a stator yoke and a field magnet. The field magnet is fixed onto the inner peripheral surface of the substantially cylindrical stator yoke. The stator yoke is configured by coaxially stacking a plurality of plate-like annular bodies, and the annular bodies are fixedly connected to each other by caulking at a caulking portion disposed on the annular body. In manufacture, the length of the stator yoke in the axial direction can be arbitrarily changed with the thickness of the annular body in the axial direction as a minimum unit. In case of manufacturing various stator yokes that are different in the axial length, the necessity of replacing a manufacturing machine is eliminated, thereby providing a commutator motor having the stator yoke which is low in the manufacturing costs.
