  • Patent number: 11904356
    Abstract: A highly-sensitive ultrasonic transducer with good yield is provided. The ultrasonic transducer includes a cavity layer, a pair of electrodes positioned above and below the cavity layer, insulating layers disposed above and below each of the pair of electrodes, and a filled hole that penetrates, in a vertical direction, at least a portion of the insulating layers positioned above the cavity layer. When the ultrasonic transducer is viewed from above, each electrode of the pair of electrodes includes, at a position that overlaps the embedded hole, a non-electrode region where the electrodes are not formed.

  • Patent number: 9688093
    Abstract: An enclosing-sealing device for preparing a sealed matter by sealing an envelope with a content enclosed in the envelope includes a content formation unit, an envelope formation unit, a content delivery unit, a seal unit, a delivery timing determiner, and a delivery controller. The content delivery unit delivers the content delivered from the content formation unit to the envelope formation unit such that the content is enclosed in a sheet of envelope paper while being folded. The seal unit seals the envelope delivered from the envelope formation unit with the content enclosed in the envelope. The delivery timing determiner determines a delivery timing of the content by the content delivery unit based on inputted information about at least one of the content and the envelope. The delivery controller controls the content delivery unit to deliver the content to the envelope formation unit in accordance with the determined delivery timing.

  • Patent number: 8396919
    Abstract: A hypertext displaying apparatus in which when a link destination indicated in stored data is designated, a processing section instructs a transmission/reception section to download hypertext data at the link destination. Additionally, the processing section instructs a history storage section to register an identifier of the currently-displayed stored data. If a user indicates a “previous content” instruction, the processing section reads from a stored information storage section the stored data corresponding to the identifier registered in the history information storage section, so that the stored data is displayed on a screen.

  • Patent number: 8389606
    Abstract: The present invention relates to an asphalt mixture including aggregates, a polyamide resin and asphalt, wherein the polyamide resin has a softening point of from 60 to 150° C., and is compounded in an amount of from 3 to 90% by mass on the basis of a total amount of the polyamide resin and the asphalt; and a paving method using the asphalt mixture. The asphalt mixture of the present invention provides a pavement which is free from rutting and torsional breakage and exhibits a high oil resistance. The pavement obtained from the asphalt mixture is free from fracture and can be prevented from suffering from occurrence of rutting and torsional breakage even when leakage of oils over a surface of the pavement occurs.

  • Patent number: 8346154
    Abstract: A conveyance control mechanism for a printer including an image forming unit forming an image on a sheet being conveyed on a conveyance route, includes a curl detector configured to detect a curl of the sheet conveyed on the conveyance route, in an upstream of the image forming unit on the conveyance route. The conveyance route controller may drive and stop the conveyance route differently depending on whether the curl detector detects a curl at either a front end or at a position other than the front end. When the curl detector detects a curl of the sheet, an image forming route where the image forming unit performs an image formation may be separated and retreated from the conveyance route and the sheet being conveyed may be discharged onto the retreated image forming route.

  • Patent number: 7499241
    Abstract: A media cartridge autoloader is disclosed. A rotary arm that operates a cartridge transporter is rotated in one direction to reach a reference position. With reference to the reference position, the rotary arm is rotated through a predetermined angle in the opposite direction to reach a position, which is defined as a home position. The rotary arm includes a flag array, and a non-flag section at an end of the flag array. A photo sensor detects the arrival of the rotary arm at the reference position in response to a detection of the non-flag section.

  • Patent number: 6677230
    Abstract: A layer comprising a second metal silicide as a major constituent element or a layer comprising a second metal as a major constituent element is formed simultaneously by one single chemical vapor deposition process to the bottom surface of two out of there groups of openings etched in a dielectric film on a substrate. A surface comprising silicon as a major constituent element is exposed at each bottom (“through holes or local interconnection holes”) of the first group of openings, a surface comprising a first metal silicide as a major constituent element is exposed at each bottom of the second group of openings, and a surface comprising a first metal as a major constituent element is exposed at each bottom of the third group of openings. The manufacturing method provides low contact resistance and sufficiently small junction leakage current from a diffusion layer in connection with plugs or local interconnections, even if the etched area of the openings are of different depths, shapes, or sizes.
