  • Patent number: 11876502
    Abstract: A surface acoustic wave device includes a piezoelectric substrate, an interdigital transducer (IDT) electrode on the substrate, a cover over the substrate and IDT electrode, and hollow spaces between the IDT electrode and the cover. The hollow spaces are defined by partition supports between the substrate and the cover. The partition supports include a first and second partition supports extending in a first direction without contacting each other. The first and second partition supports each include first and second ends along the first direction. The first and second direction perpendicular to the first direction. The first end of the first partition support is closer to an outer periphery of the substrate than is the second end, and the first end of the second partition support is farther away from the outer periphery than is the second end.

  • Patent number: 10831123
    Abstract: An image forming apparatus includes a laser scanner unit configured to scan a photosensitive drum through use of a laser beam deflected by a reflection face of a polygon mirror, an engine controller, and an image controller. The engine controller generates an image formation BD signal synchronized with a BD signal output from the laser scanner unit. The image controller stores in advance, into a ROM, difference information indicating a difference between pulse cycles of image formation BD signals corresponding to respective reflection faces, acquires a difference between pulse cycles of an image formation BD signal output at the time of image formation, and compares the acquired difference with the difference information stored in the ROM to identify a reflection face.

  • Patent number: 9921995
    Abstract: In a case where a changeover request indicating to change over setting of an end point is received from an external apparatus, an information processing apparatus decides whether or not data is being transferred from the end point to a memory of the information processing apparatus. Then, in a case where it is decided that the data is being transferred from the end point to the memory, the information processing apparatus does not change over the setting of the end point.

  • Patent number: 9648190
    Abstract: An image forming apparatus capable of returning from the power saving state and performing user authentication by one action of holding an authentication card over a card reader even when the apparatus is in the power saving state. The apparatus performs short-distance wireless communication with an external device. A controller performs control processing including at least authentication processing. When short-distance wireless communication with the device is started, a short-distance wireless communication section delivers a return-starting interrupt, to the controller, receives authentication data from the device to thereby store the authentication data during returning of the apparatus. The controller performs authentication processing based on the stored authentication data after returning of the apparatus from the power saving state, and notifies the device of an authentication processing result by a different channel.
