  • Publication number: 20210165012
    Abstract: A road surface damage detection device is configured to calculate, for each of road sections, a maximum variation rate that is a maximum value of a variation amount of a wheel speed per unit time in each of vehicles. The device is configured to periodically select, for each of the road sections, a maximum value from the maximum variation rate of each of the vehicles in a prescribed period, set the selected maximum value as a section maximum variation rate, and determine whether or not the road surface damage has occurred by comparing a determination target value with a positive threshold, the determination target value being obtained by subtracting a comparison value, based on at least one of the section maximum variation rates set before last time, from the section maximum variation rate that is set latest.

  • Patent number: 8545217
    Abstract: A label manufacturing apparatus has a thermal head with heating elements for heating at least a part of a heat sensitive adhesive sheet to place it into an adhesive state when the heat sensitive sheet is transported through a preselected position of the label manufacturing apparatus in which the heat sensitive sheet contacts the heating elements of the thermal head. A control device selectively operates the heating elements of the thermal head in synchronization with timing of transporting of the heat sensitive adhesive sheet through the preselected position to thereby heat the part of the heat sensitive adhesive sheet and place into the adhesive state, and stops operation of the heating elements so that a trailing end portion of the heat sensitive sheet is not heated and is not placed into an adhesive state when the trailing end portion reaches the preselected position.

  • Patent number: 7998294
    Abstract: In a label manufacturing method, at least a part of a heat sensitive adhesive sheet is heated to develop adhesive properties by using a thermal head having heating elements and by using a transporting unit that transport the heat sheet to pass through a position contacting with the heating elements. Image data is generated on an image area of the sheet and an image editing process is performed so as to divide the image area into at least two types of parts that are set as heated and non-heated parts, respectively. An edited image obtained as a result of the image editing process is input as a heating pattern. The thermal head and the transporting unit are driven based on the input heating pattern and the heating elements are selectively operated in timed synchronization with the transportation of the sheet. In the image data generating step, the image area is displayed on a display as a binary image including a colored part and a non-colored part.

  • Publication number: 20100304319
    Abstract: In order to suppress adhesion and accumulation of a heat sensitive adhesive onto a thermal head from a trailing end portion in a transporting direction of a heat sensitive adhesive sheet, to thereby enable smooth and continuous transporting of a plurality of the heat sensitive adhesive sheets, a thermal head and transporting means are driven so that a plurality of heating elements of the thermal head are selectively operated in synchronization with timing of transporting of a heat sensitive adhesive sheet (2) by the transporting means. Thus, at least a part of the heat sensitive adhesive sheet (2) is heated to develop adhesive properties. When a trailing end portion (2b) in the transporting direction of the heat sensitive adhesive sheet (2) reaches a position at a predetermined distance (for example, 2 mm) before a position contacting with the heating element of the thermal head, heating by the thermal head is stopped.

  • Patent number: 7791624
    Abstract: Provided is a thermal activation device capable of preventing a heat-sensitive adhesive sheet from being partially excessively heated, keeping a short distance between a contact between a thermal head and a platen roller, and a discharge port, and preventing a structure of the thermal activation device from being complicated and a size thereof from increasing. While a heat-sensitive adhesive sheet (2) is transported along a transport path (15) through rotations of insertion rollers (3) and a platen roller (5), a heat-generating portion (4a) of the thermal head (4) is caused to generate heat, thereby thermally activating a heat-sensitive adhesive layer of the heat-sensitive adhesive sheet (2). When a trailing edge of the heat-sensitive adhesive sheet (2) reaches a position where the trailing edge thereof is not in contact with the platen roller (5), a transporting force is not transmitted to the heat-sensitive adhesive sheet (2), thereby stopping transportation thereof.

  • Patent number: 7556445
    Abstract: A thermal activation device has a thermal activation head that thermally activates a heat-sensitive adhesive layer of a sheet material having a printing layer on one surface of a sheet-like base material and the heat-sensitive adhesive layer formed on the other surface thereof. A platen roller conveys the sheet material and is disposed in pressure contact with the thermal activation head so that the platen roller and the thermal activation head apply a holding force on the sheet material. A pair of conveyor rollers hold and convey the sheet material and are disposed on a downstream side of the thermal activation head in a conveying direction of the sheet material. A holding force applied on the sheet material by the pair of conveyor rollers being larger than a holding force applied on the sheet material by the platen roller and the thermal activation head.

  • Patent number: 7478956
    Abstract: A printer selectively prints on heat-sensitive adhesive sheets and ordinary sheets that have no heat-sensitive adhesive. The printer has a printing unit that prints on one surface of a sheet and a printing platen roller that transports the sheet in a forward direction. A cutter unit cuts the printed sheet to a predetermined length, and a thermal activation unit disposed downstream of the cutter unit has a thermal head for heating the other surface of the sheet and a thermal activation platen roller that transports the sheet in the forward direction. A detector detects whether the sheet is a heat-sensitive adhesive sheet or an ordinary sheet, and a control device controls operation of the thermal activation unit so that both the thermal head and the thermal activation platen roller are operated in response to detection of a heat-sensitive adhesive sheet and so that the thermal activation platen roller but not the thermal head is operated in response to detection of an ordinary sheet.
