摘要:
An electrochemical device comprises, at least, a first electrode, a second electrode, and an electrolyte layer having an ionic conductivity. The first and second electrodes oppose each other by way of the electrolyte layer. The first and second electrodes comprise a composite particle containing an electrode active material, a conductive auxiliary agent having an electronic conductivity, and a binder adapted to bind the electrode active material and conductive auxiliary agent to each other. In the composite particle, the electrode active material and conductive auxiliary agent are electrically coupled to each other without being isolated.

Composite particles for an electrode of the invention are produced through a granulating step in which, a conductive additive and a binder are brought into a close contact with particles consisting of the electrode active material to integrate with each other. The granulating step preferably comprises a process for preparing a stock solution comprising the binder, the conductive additive and a solvent, a process for forming a fluidized bed by throwing particles of electrode active material into a fluidizing bathe and a process for bringing the particles of electrode active material and the particles of conductive additive into a close contact with the binder by spraying a stock solution into the fluidizing bathe, allowing the stock solution adhering to the particles of electrode active material and drying the same to remove the solvent from the adhered stock solution. Composite particles thus obtained are used as the constituent material for electrode, and further, the electrode is used as an anode and/or cathode of an electrochemical element; thereby, the internal resistance of electrode can be reduced satisfactorily and the power density of the electrochemical element can be increased satisfactorily.

The present invention provides a manufacturing method for an impeller with which molding and high-quality finishing can be performed extremely easily and quickly through resin molding using a die, and an impeller manufactured by the impeller manufacturing method. A metallic bush is disposed in a die, whereupon a resin material is injected through a gate in the die. A connecting portion between an unnecessary resin portion formed from residual resin material in the gate and a resin impeller main body molded around the bush is formed to be thin, and the unnecessary resin portion is removed from the impeller main body using pushing or withdrawing means.

The present invention provides an amplifying apparatus including, two amplifiers for receiving input signals in common and for outputting their respective amplified signals, a combiner for combining the output signals of the two amplifiers and for outputting a combined signal, the amplifying apparatus which inhibit the distortion component in the output of amplifiers in the transition state. This amplifying apparatus comprises, a predistortion unit for determining a distortion compensation component based on the output of the combiner and for predistorting the input based on the determined distortion compensation component, and a gain control unit for attenuating the inputs to set lower than in the steady state by reducing the gain in the transition from two amplifier operation to one amplifier operation, or in the transition from one amplifier operation to two amplifier operation, or at the time of removal or attachment the amplifiers.

An image receptor surface which receives an image of a sublimation dye thermally transferred thereto from a foundation sheet for formation of the image therein, the image receptor surface comprising a thermochromatic layer. The thermochromatic layer is a layer of a thermochromatic ink, and contains at least either one of an epoxy resin and an epoxy acrylate resin. The thermochromatic layer reversibly changes its color between an image concealable color and transparence in a predetermined temperature range. The image receptor surface may be formed of any of various materials or articles such as metals, wood materials, glass materials, ceramics, plastics, fabrics and fibrous materials for any applications, especially a mug.

An abrading machine and abrading method are provided which permit a workpiece to be abraded without damage even in the case of heavy stock removal. A work holding member for mechanical abrasion includes a first holding member with a hole for receiving a workpiece and which transmits external drive force to the workpiece, and a second holding member placed on the first holding member and also having a hole for receiving the workpiece. The second holding member is removed after a predetermined volume of stock is abraded away; the workpiece is then abraded to a target thickness while being held by the first holding member alone. Thicknesses t1 and t2 of the first and second holding members are given by T1>t1+t2 and (½)T2≦t1, where T1 and T2 represent the workpiece thickness before and after abrasion, respectively.
