Abstract: A method and a system suitable for predicting the costs of implementing cogenerations in small-scaled places of business and ordinary homes. Transmitters (3) located at the respective ones of facilities transmit, by radio, data of electric power consumption amounts of the facilities as measured by electric power meters (1) and data of gas consumption amounts of the facilities as measured by gas meters (2), which are received by a receiver (4). Estimation means (5) uses an estimation program to provide, from the received data, cost estimations of a case when cogenerations are implemented in the facilities. Annual cost estimation means provides, from the estimation results of the estimation means (5), annual cost estimations.

Abstract: An image forming device includes an image forming part which forms an image on a recording medium; a recording medium switchback portion which receives the recording medium on a first run, one side of which has been printed when passing the image forming part, and sends the recording medium for a second run; a recording medium path which communicates with the recording medium switchback portion so as to send the recording medium to and from the recording medium switchback portion; an inverted recording medium transfer path through which the recording medium is sent to the image forming part again with an upper surface and a lower surface of the recording medium reversed; and a recording medium transfer part which transfers the recording medium along the inverted recording medium transfer path.

Abstract: An ink cartridge connectable to a print head having a supply pipe which receives a supply of ink includes a casing having a first, upper chamber and a second, lower chamber communicating with each other via a communicating hole and storing the ink, a porous body provided in the first chamber and storing the ink by a negative pressure, and a connection part provided in the second chamber and connectable to the supply pipe. The connection part has normally closed valve means for communicating the print head with the second chamber by opening when the supply pipe is inserted into the connection part. The ink cartridge includes a connecting pipe extending from the first chamber into the second chamber and a filter member covering the opening of the connecting pipe in the second chamber. The filter member releases air from the connecting pipe upwardly into an upper region of the second chamber.

Abstract: An image forming device includes an image forming part which forms an image on a recording medium; a stacker which stores the recording mediums one on another; a recording medium switchback portion which receives the recording medium on a first run, one side of which has been printed when passing the image forming part, and sends the recording medium for a second run; an inverted recording medium transfer path through which the recording medium is sent to the image forming part with an upper surface and a lower surface of the recording medium reversed; a recording medium transfer part which transfers the recording medium along the inverted recording medium transfer path; a recording medium position correcting part, located at the inverted recording medium transfer path, which corrects a position in a width direction of the recording medium, and a control means for controlling the recording medium position correcting part with a particular operation timing so that the recording medium position correcting part

Abstract: A backup unit is provided with respect to a nozzle of a print head for printing by injecting ink, and sucks the ink from the nozzle, the backup unit including: a nozzle cap sealing the nozzle by making contiguous contact with the print head; a pump; and an ink path communicating the nozzle cap and the pump; wherein the pump includes: a bellows part having an internal space formed therein; a movable rod fixed to the bellows part and having an ink passage therein; a slide valve provided in the bellows part and slidable with respect to the rod, the slide valve closing and opening a hole provided at one end of the ink passage with respect to the internal space, depending on a position of the movable rod; an ink inlet provided at the other end of the ink passage and communicating with the ink path; and an ink outlet communicating with the internal space depending on a position of the slide valve, the slide valve having a stroke shorter than a stroke of the rod, a volume of the internal space within the bellows par

Abstract: A recording apparatus which realizes attraction of ink with a low recording voltage, includes a thin plate member (2) having many fine holes (3). An ink reserving member (4) is provided closely in the one side of the thin plate member (2) and is impregnated with conductive ink (8). An electrode member (1) is provided interposing a recording medium (100) on the other side of the thin plate member (2) and effectuates the electrostatic force to attract the conductive ink (8) in the one side through the holes (3).

Abstract: A pressure damper of an ink jet printer provided in an ink feed line between an ink jet head and an ink tank to absorb a pressure fluctuation in the ink feed line, wherein the pressure damper has a damper body provided with a pressure absorbing chamber and a filter incorporated therein to filter the ink.
