Abstract: A communication apparatus system includes a relay apparatus and a communication apparatus which are connected to a network, to which a service providing apparatus for an electronic-file storing service is connected. The communication apparatus includes: an address-get-request transmitting unit that transmits a request for getting an upload destination address to the relay apparatus; a receiving unit that receives the upload destination address and a template for an upload message from the relay apparatus; an upload-message generating unit that generates the upload message including the electronic file and the upload destination address according to the received template; and an upload-message transmitting unit that transmits the generated upload message to the service providing apparatus to upload the electronic file in the electronic-file storing service.

Abstract: A data managing apparatus having a word extracting portion that extracts one or a plurality of words from document data and a correlating portion that correlates the words extracted by the word extracting portion with related data related to the document data, includes a frequency storage portion having information about a frequency of each of the words stored thereon for each word; an infrequently-appearing word selecting portion that selects an infrequently-appearing word having the frequency lower than a given threshold value predetermined among the words extracted by the word extracting portion based on the information stored in the frequency storage portion; and a frequency updating portion that updates the information about frequency stored in the frequency storage portion in accordance with extraction by the word extracting portion or correlation by the correlating portion, the correlating portion correlating the infrequently-appearing word selected by the infrequently-appearing word selecting portion

Abstract: An apparatus for controlling an elevator which has a high energy-saving effect based on charging while using a low-capacity and low-priced secondary battery. The apparatus has a converter for converting an alternating current from an ac power supply into a dc power by rectifying the alternating current, an inverter for driving an electric motor by converting the dc power from the converter into variable-voltage variable-frequency ac power, the motor being driven for the operation of the elevator, and a power accumulator connected to a dc bus between the converter and the inverter. The power accumulator accumulates dc power from the dc bus during regenerative operation of the elevator, and supplies the accumulated dc power to the dc bus during power-drive operation of the elevator.

Abstract: A roller made of a synthetic resin, used for a belt-conveyor, by means of utilizing insert-forming injection molding, placing a thin-walled metallic housing for containing a roller bearing therein, at the innermost boss portion, for concentrically forming a roller body integrally with the metallic housing. The inner race of the bearing is press-fitted onto the roller shaft, and the outer race thereof is press-fitted inside the metallic housing. A roller of such a construction will resist or absorb most of the inherently large thermal expansion and contraction of a synthetic resin made article, and thus enables the life of the resin made rollers to be elongated far beyond expectation.

Abstract: A roller made of a synthetic resin, used for supporting a conveyor belt, possesses an anti-electrostatic-charge capability. Utilizing insert-forming injection molding, a conveyor carrier roller body is integrally formed concentrically about a thin walled metallic housing containing a rotary bearing assembly therein at the innermost position for concentrically forming a conveyor carrier roller body integrally with the metallic housing. The inner race of the bearing is force-fitted onto the roller shaft and the outer race of the bearing is force-fitted inside the metallic housing. A roller of such a construction will readily discharge the static electricity charged on the surface of the roller by conducting it to ground through a snap ring (fitted in a circular groove formed inside of the boss portion of the roller), the housing, the bearing, and the shaft. The snap ring positioned adjacent the electricity charging place functions like a lightening conductor through the point-discharging.
