Abstract: In a maintenance/recovery device for a liquid discharging device, a cap member covers a surface of a nozzle of a liquid discharging head, the liquid discharging head discharging a droplet of a recording liquid from the nozzle. A resilient contact member is provided in the cap member to come in contact with the surface of the nozzle. A recess-forming member is providing in the cap member to form a recess for receiving the recording liquid attracted from the nozzle. The contact member and the recess-forming member are integrally formed by molding, the recess-forming member is made of a resin material containing a water repellent agent, and the recess-forming member is provided to have at least two slopes being inclined toward an outlet at a bottom of the recess.

Abstract: A head capping member for capping an ejection face of a liquid ejecting head which face is provided with a nozzle for ejecting a liquid drop is provided, which includes a contact part which contacts the ejection face of the head and is made of an elastic member and a recess which forms a closed space together with the ejection head when the contact part contacts the ejection head, wherein a flat part is formed around the recess and an absorbing member is provided on the flat part so as to cover the recess.

Abstract: A head driving control apparatus for driving a pressure generation part in a droplet discharging head outputs a driving signal including: a first waveform element for contracting the volume of a pressurizing chamber without discharging a droplet; a second waveform element for keeping a contracted state until a meniscus in a nozzle moves toward the pressurizing chamber; a third waveform element for expanding the volume of the pressurizing chamber from the contracted state; a fourth waveform element for keeping an expanded state; and a fifth waveform element for contracting the volume of the pressurizing chamber to discharge a droplet.

Abstract: An image forming apparatus having a recording head for discharging an ink includes a fuel cell unit and a water supply unit. The fuel cell unit generates power for the image forming apparatus and water when the power is generated in the fuel cell unit. The water supply unit supplies the water, generated by the fuel cell unit, to an ink accumulation area in the image forming apparatus.

Abstract: The present invention comprises a first authentication server for determining whether or not a client terminal should be connected to a first terminal server, on the basis of personal information input from the client terminal, creating first ticket data by encoding a client parameter, and transferring the first ticket data to the second terminal server, and a second authentication server for detecting whether or not the client parameter is valid and whether or not the first ticket data has been used, creating second ticket data by encoding the client parameter, comparing the first and second ticket data, and supplying the second terminal server with data indicative of whether or not the second terminal server should be connected to the client.

Abstract: In a wireless input transmission device, data is entered by input means such as pointing device, the value of the data is checked when transmitting the data, and when the data value is small and does not require the specified number of bits, the number of bits is decrease to one half or one quarter, or the difference from the previous time is transmitted, or the data is omitted if the present data is same as the previous data, and such information is given to the data quantity information bit, and data to be transmitted, data quantity information bit, and necessary data for transmission are added, and the transmission data is composed by decreasing the data quantity in one-input information depending on the data value and transmitted to the wireless receiver, where the transmission data is decoded according to the data quantity information bit and the received result is sent by wire to the main apparatus such as personal computer, word processor, other information processing apparatus, or household game machi

Abstract: Methods of fabricating electrically alterable non-volatile semiconductor memory cells are provided. The methods include the steps of forming consecutively two paris of side walls defined at least partially by a floating gate, a control gate and dielectric layers to which dopant implantation into source region is self-aligned. Using such side walls provides accurate channel lengths of select gate transistors for uniform memory cell characteristics.
