  • Patent number: 11866285
    Abstract: Provided is a coating film transfer tool having a pivotable transfer head and a tape guide for transfer tape, and capable of satisfactorily transferring a coating film. In some examples, such a coating film transfer tool includes tape guides respectively having lower sides disposed on a first side of a main body where the transfer tape passes before coating film transfer, and upper sides disposed on a second side of the main body where the transfer tape passes after coating film transfer passes. An interval between the upper sides is wider than an interval at a position where an interval between the lower sides is narrowest.

  • Patent number: 11261050
    Abstract: A coating film transfer tool in which a rotational torque with the least variability may be generated without being affected by a surface state of a resilient body may include: a paying-out core having a coating film transfer tape wound thereon; and a rewinding core that rewinds the coating film transfer tape after use. The paying-out core and the rewinding core are interlocked via a power transmission mechanism in a case. The transmission mechanism generates a rotational torque by a frictional force on a sliding surface between components, by using a restoring force of a resilient body. The resilient body is configured to rotate integrally with a component A that comes into contact with one end of the resilient body and a component B that comes into contact with the other end.

  • Patent number: 8791385
    Abstract: In a method for scribing fragile material, a laser beam is irradiated onto a work plate of the fragile material. The work plate is heated by absorption of the irradiated laser beam and generating thermal stress by the heating. The laser beam is formed by a plurality of laser beam groups arranged along a beam scanning direction on a same line, and the plurality of laser beam groups are divided into two groups. One takes charge of initial heating and rising up temperature of the work plate, and another takes charge of temperature holding of the work plate. The laser beam intensity corresponding to each of the laser beam groups is adjusted so as to obtain optimum values. By the method, it is possible to remarkably increase scribing speed of the work plate of the fragile materials without increasing heating temperature.
