摘要:
A process for producing 2,6-dimethylnaphthalene by subjecting 2,7-dimethylnaphthalene to an isomerization reaction, wherein the isomerization reaction is carried out by the use of a metallosilicate catalyst that comprises a metallosilicate having a main cavity defined by a ten-oxygen-membered ring, that is in the form of aggregates of fine crystals of the metallosilicate, the external surface area of the aggregate as calculated from t-plot analysis made in the nitrogen adsorption method being 25 m2/g or more, and that has been treated to inactivate acid centers present on the external surfaces of the fine crystals until the rate constant basic value N becomes 0.5 or less.
摘要:
In order to provide a charge/discharge technology for controlling an assembled battery system without promoting degradation or reduction in the lifetime of the assembled battery system, the assembled battery system includes a function for controlling charge and discharge power of a plurality of units each including a secondary battery and a power converter as one unit, the plurality of units being electrically connected in parallel to each other. When each unit performs charge or discharge by at least one or more times, charge and discharge of the unit are controlled so as not to be performed until a predetermined pause time period elapses.

The present invention provides a metal powder composed of tantalum or niobium that achieves both sinterability and fluidity and the manufacturing method thereof. The present invention also provides a tantalum or niobium powder that enables the manufacturing of an anode for a solid electrolytic capacitor in which holes are formed for a conductive polymer-containing solution to pass through, without using a hole molding material or pore forming material. Furthermore, the present invention provides an anode for a solid electrolytic capacitor that enables the manufacturing of a high-volume and low ESR solid electrolytic capacitor. The present invention further provides a manufacturing method of a metal powder that allows the manufacturing of a metal powder of a given diameter range from a raw powder at high yield, without requiring a lot of work and time.

It is possible to stably supply an electric signal to an ultrasonic generation element without causing friction or damage on parts or without requiring periodical parts exchange. A reception coil (11) connected to a vibrator (6) is wound on the outer circumference of a housing (1) constituting a shaft (30) of a machining spindle (101). The reception coil (11) is surrounded coaxially by a transmission coil (12) at an appropriate interval. A predetermined electric signal outputted from an ultrasonic drive device (21) for driving the vibrator (6) is applied to the transmission coil (12). The predetermined electric signal may be applied to the vibrator (6) via the reception coil (11) by electromagnetic induction between the transmission coil (12) and the reception coil (11).

A fuel supply system for a fuel cell supplies fuel to a fuel cell of an electronic equipment. The fuel supply system includes a pressure regulator for regulating primary pressure to secondary pressure, and a pair of cylindrical fuel cartridges which are connected to a pair of inlets on a primary pressure side. The inlets being provided to both sides of the pressure regulator are arranged in mutually opposite directions. Fuel having primary pressure is took in from the inlets into the pressure regulator. The fuel cartridges are placed to both sides of the pressure regulator along a substantially straight-outer edge of the electronic equipment.

The present invention relates to an insulator to be disposed in an armature core having a plurality of radially-formed salient poles. The insulator comprises a winding aligning portion having an approximately V shape (forming an angle of 60 degrees) and getting narrower from an outer side to an inner side in a radial direction of the armature core approximately at the middle between the salient poles to position a winding disposed at a first layer which is a most inner side in the radial direction of the armature core approximately at a middle between the salient poles. By this structure, it is possible to align the windings on the second layer and beyond, thereby preventing a dig-in and the like of the windings and hence preventing faulty insulation between the windings.
