Publication number: 20040246237Abstract: The present invention provides effective information search means, and/or effective acquired information submission means, without overtly expressing an intent (e.g., through the depression of a search button) to acquire information. In an example embodiment, the kana-kanji conversion routine is activated, and a character string is input using voice, a keyboard or a graphic entry process. Then, a conversion key is depressed to convert the input character string into kanji. Upon the depression of the conversion key, the homonym candidate selection routine is initiated, and the conversion candidate is presented. In response to the depression of the conversion key, or the change of the conversion candidate in the homonym candidate selection routine, the information access routine is activated. Then, the information access procedure is performed, and the search results are acquired. Thereafter, the search results are presented.Type: ApplicationFiled: December 11, 2001Publication date: December 9, 2004Inventors: Chieko Asakawa, Hironobu Takagi, Hiroshi Nomiyama

Publication number: 20040246239Abstract: A circuit for an acoustic wave switch or sensor having a resonant acoustic wave cavity detects a touch or sensed event using a time domain approach. The circuit includes a controller that drives an acoustic wave transducer to generate a resonant acoustic wave in the acoustic wave cavity during a first portion of a sampling cycle. In a second portion of the sampling cycle, the controller monitors the time that it takes for the acoustic wave signal from the transducer to decay to a predetermined level.

Publication number: 20040246240Abstract: Systems, methods, and computer-readable media are used to determine whether specific electronic pen gestures with respect to pen-based computing systems should be processed as “press-and-hold” gestures (e.g., to activate right mouse button click actions).

Publication number: 20040246281Abstract: A ballot marking system and apparatus for marking a paper ballot listing a plurality of candidates which includes a marking space for each candidate which can be either hand-marked by a voter, or machine-marked by the marking apparatus. The marking apparatus includes a touchscreen device on which the voter can enter his selections. The touchscreen is pivotally mounted atop the ballot marking apparatus such that it fits within a recess in the apparatus housing when in its closed position, and is ergonomically presented to the voter when in its open position.Type: ApplicationFiled: June 4, 2003Publication date: December 9, 2004Inventor: Joseph M. Vanek

Publication number: 20040246282Abstract: A drawing device is provided that applies drawing liquid containing a drawing material dissolved or dispersed in a solvent onto a substrate. The drawing device includes a liquid drop emitter having a liquid drop ejection head that ejects the drawing liquid onto the surface of the substrate, a substrate stage having the substrate mounted thereon, moving means for relatively moving the liquid drop ejection head or the substrate stage, and control means for controlling at least one of the liquid drop ejection head and the substrate stage. A wall is disposed on at least one of the liquid drop ejection head and the substrate stage to prevent the solvent from flowing out.Type: ApplicationFiled: March 26, 2004Publication date: December 9, 2004Inventor: Takahiro Usui

Publication number: 20040246283Abstract: A fluid reservoir sensing system includes a pair of optical prisms that reflect light when a fluid level is below one of the pair of prisms. The pair of optical prisms includes a low prism usable to sense a low liquid level in the fluid reservoir, and a high prism usable to sense a high liquid level in the fluid reservoir. The fluid reservoir sensing system optionally includes an emitter and a photosensor. The emitter projects light through at least one of the low prism to the low incident surface and the high prism to the high incident surface. The photosensor senses light reflected from the low prism while the liquid is below the low prism. The photosensor also senses light from the high prism while the liquid level is below the high prism.Type: ApplicationFiled: June 6, 2003Publication date: December 9, 2004Applicant: FUJI XEROX CO., LTD.Inventors: Eric A. Merz, Brian S. Hilton

Publication number: 20040246284Abstract: At a predetermined position during the lateral movement of a carriage 10, a gap switching mechanism 30 for switching a gap between a recording head 15 and a recording medium is provided. The recording head 15 is mounted facing downward on the carriage 10. A part close to one side on a lower end of the carriage is slidably and pivotably supported by a guide shaft 11 of a round shaft shape. A switching block member 13 provided with several abutment portions 52 and 53 with different heights, which are positioned so as to be opposed to a slide portion 12a at an upper end of a frame 12 extending in a vertical direction along a back of the carriage. The A switching block member 13 is pivotably supported by the carriage. A first pushing portion 56 is located at a left end of the frame so as to abut against the switching block member 13.Type: ApplicationFiled: May 19, 2004Publication date: December 9, 2004Inventors: Shunji Murai, Masatoshi Yamada, Kenji Samoto

Publication number: 20040246285Abstract: A printing apparatus, a printing method, a computer program, and a computer system for decreasing ink consumption amount are provided. A printing apparatus comprises a print head being movable in a main scanning direction and printing medium feeding means for feeding a printing medium, and carries out printing on the printing medium by ejecting ink from the print head, wherein a skew of the printing medium is obtained by detecting, at a plurality of points, a leading edge that is fed first among the edges of the printing medium by the printing medium feeding means, and wherein a starting position, an ending position, or both of these for ejecting ink from the print head, which moves in the main scanning direction, is changed according to the skew that has been obtained.Type: ApplicationFiled: April 1, 2004Publication date: December 9, 2004Inventor: Hironori Endo

Publication number: 20040246286Abstract: An automatic printer 1 prints a portion of a pattern onto an allocated region of a print medium 3, picks up the image of this printed pattern using an image pickup device 6, and after the image pickup, forwards the printed region portion to position a next allocated region in an effective printing region 16. Then, the automatic printer 1 again picks up the image of the above-described printed pattern using the image pickup device 6, and compares these two images. When these images deviate from each other, the automatic printer 1 makes a correction, and performs printing in a state where the joint position of the pattern precedently printed and that of a pattern to be next printed conformed to each other.Type: ApplicationFiled: April 5, 2004Publication date: December 9, 2004Inventor: Reiji Arikita
