  • Publication number: 20240367445
    Abstract: A printing apparatus includes a conveyance unit configured to be able to convey a roll sheet that is wound in a rolled shape and a cut sheet that is not wound in a rolled shape to a printing unit configured to print an image; a receiving unit detachably attached to the apparatus, the receiving unit being configured to receive the cut sheet onto which printing has been performed by the printing unit; a detection unit configured to detect whether the receiving unit is attached to the apparatus; and a holding unit configured to, in a case where the detection unit detects that the receiving unit is not attached to the apparatus, nip to hold the cut sheet onto which printing has been performed by the printing unit.

  • Patent number: 12115781
    Abstract: There is provided a printing apparatus. A printing unit prints an image on a printing medium and is able to move. A cutter unit is able to connect with or separate from the printing unit, and, by following a movement of the printing unit, cuts the printing medium. A setting unit sets, in accordance with a size of the printing medium, a standby position of the cutter unit.

  • Publication number: 20240269996
    Abstract: There is provided a printing apparatus comprises a holding unit configured to hold a roll sheet. The printing apparatus performs: supplying the sheet by rotating the roll sheet held by the holding unit; nipping and conveying the supplied sheet; performing printing on the conveyed sheet; detecting occurrence of a print medium jam of the sheet; and, if the printing apparatus has detected a print medium jam of the sheet, performing a control process of supplying the sheet in a state in which the conveying is stopped.

  • Patent number: 8127594
    Abstract: A gas sensor including: a gas sensing element including first and second ceramic layers. The first ceramic layer has a first through hole and a first through hole conductor covering an inner surface thereof. The first ceramic layer includes a first conductor which includes: a first peripheral conductive portion electrically connected to the first through hole conductor; a first lead portion that is narrower than the first peripheral conductive portion; and a first contact conductive portion that is wider than the first lead portion. The first peripheral conductive portion, the first lead portion and the first contact conductive portion are integrally formed and arranged in this order in a longitudinal direction. The second ceramic layer includes a second conductor electrically connected to at least the first contact conductive portion.

  • Patent number: 7951277
    Abstract: A prismatic multilayer gas sensor element and method of making the same, the prismatic multilayer gas sensor element (1) having a substantially rectangular cross section, and including a gas-sensing cell portion (2) formed at a distal end portion of the prismatic gas sensor element (1); and a posterior lead portion (3) adjoining the gas-sensing cell portion (2). The longitudinal lateral surfaces of the posterior lead portion (3) are coated with a non-porous alumina layer (11), the non-porous alumina layer (11) having a multilayered structure including at least a joining layer (11a) and a surface layer (11b). The longitudinal lateral surface of the gas-sensing portion (2) is not coated with a non-porous alumina layer.

  • Patent number: 7041207
    Abstract: A solid electrolyte layer or body capable of being co-fired with an insulating ceramic substrate or body to be used as a gas sensor laminate. The gas sensor laminate is preferably composed of an alumina substrate (1) and an oxygen-ion conductive solid electrolyte layer (6) bonded to the alumina substrate (1) by firing. The oxygen-ion conductive solid electrolyte layer or body is formed from partially or wholly stabilized zirconia, which layer contains alumina in an amount of 10% to 80% by weight, particularly 30% to 75% by weight. In this manner, another ceramic layer; particularly, a ceramic layer (7) of alumina can further be bonded to the oxygen-ion conductive solid electrolyte layer. The relative density of the ceramic layer can be 60% to 99.5%, preferably 80% to 99.5%.
