摘要:
An objective is to improve the mechanical strength and the durability of a current collector for a non-aqueous electrolyte secondary battery and to allow an active material layer to be efficiently carried on the surface of the current collector with high adhesion. This objective is achieved with the use of a pair of processing means being disposed such that the surfaces thereof are in press contact with each other to form a press nip for passing a sheet material therethrough and having a plurality of recesses formed on the surface of at least one of the processing means, by passing a metallic foil for current collector through the press nip between the processing means to perform compression, thereby to form a plurality of projections on at least one surface of the metallic foil for current collector by partial plastic deformation associated with the compression.

An electrode 13 has an active material layer 12 formed on each of two whole main surfaces of a current collector 11. A part of an electrode lead 14 overlaps the electrode 13. One end face of the electrode 13 in the width direction of the electrode 13 is flush with one end face of the electrode lead 14. Joints 15 are formed at the one end of the electrode 13 in the width direction. The joints 15 join the electrode 13 and the electrode lead 14 so as to provide electrical continuity between the exposed part of the current collector 11 at the one end face of the electrode 13 in the width direction and the electrode lead 14. The joints 15 are formed, for example, by plasma welding.

A laser beam 21 outputted by a laser oscillator 3 is collected by a machining head 4, so that the surface of a roller 2 is irradiated with the laser beam. An encoder 5c outputs a signal in accordance with a rotational position of the roller 2. A control portion 24 controls the laser oscillator 3 to irradiate the roller 2 at the same spots on the surface with the laser beam 21 per rotation of the roller 2, the irradiation being repeated a plurality of times, thereby forming recesses in the surface of the roller.

A diagnosis device for diagnosing loosening of a stator core of a rotary electrical machine. The diagnosis device has: excitation means for vibrating the stator core in the radial direction; vibration detection means for detecting the vibration of the stator core in the radial direction; means for frequency-analyzing an output signal of the vibration detection means that detects vibration generated in the stator core when the stator core is vibrated by the excitation means so as to extract a measurement natural vibration mode of the stator core in a circular ring natural vibration mode; means for estimating a circular ring natural vibration mode of the stator core from shape data of the stator core; and means for determining a clamping state of the stator core by comparing the measurement natural vibration mode and a determination criterion obtained based on the estimated natural vibration mode.

An improved 8-8 mpping table system in digitally and magnetically recording video signals. Video signals coded into natural binary codes consisting of 8 bits are converted into different binary codes consisting of 8 bits constituted by patterns in which a continuous number of the 1's or the 0's does not exceed a predetermined number. In these codes, the continuous number of the 1's or the 0's is so limited that a maximum magnetization interval is reduced in magnetically recording the signals. Therefore, erroneous code is prevented from occurring in reproducing the signals.

An optical media converter system is divided into an outdoor installed optical media converter and an indoor installed unit, which are connected to each other through an electrical Ethernet cable. The indoor installed unit includes two electrical Ethernet terminations and a power source section for supplying an electrical power from indoor to outdoor. The outdoor installed optical media converter includes an optical-electric converter, optical Ethernet termination, electrical Ethernet termination, and a power source section for generating a power source by an electrical power supplied from the indoor. With the above configuration, there can be provided an optical media converter system in which the need to draw the fiber-optic cable into a home can be eliminated, cost involved in a wiring work can be reduced, and a circuit design thereof is advantageous in cost reduction.

摘要:
In order to improve the rapidity with which an automatic equalizer can be pulled in when transmitting data at high baud rates, each of the modems of secondary stations are arranged to detect the divergence of the automatic equalizer included therein and induce the issuance of a tone signal which is supplied to the primary station and induces the latter to reissue a training signal. The automatic equalizers in the secondary stations pull in on the training signal which ceases to be issued when the tone signal is no longer generated.
