摘要:
A viewer for authenticating a birefringent pattern having at least two regions having a different birefringence from each other, wherein the viewer contains a polarizing plate and at least one optically anisotropic layer laminated on the polarizing plate, a front retardation of the at least one optically anisotropic layer is 5 nm or more and the total of the front retardation of the at least one optically anisotropic layer and a maximum value of front retardation of the birefringent pattern is greater than λ/2.
摘要:
A forgery-preventing foil having a latent image and a total thickness of 20 μm or less, containing at least one patterned optically anisotropic layer having two or more regions different in birefringence property, all of the regions in the same layer being formed of the same layer-forming composition.
摘要:
A medium for preventing forgery having a hologram layer and at least one patterned optically anisotropic layer, wherein the patterned optically anisotropic layer has two or more regions comprising different birefringence property, and wherein all the regions are formed of the same composition.
摘要:
A packaging material, having at least one optically anisotropic layer which is made from substantially the same layer-forming composition and includes two or more regions different in birefringence property.
摘要:
The present invention provides a counterfeiting prevention device comprising a support, a patterned optically anisotropic layer having two or more regions of different birefringence, and a printed layer in this order, which further comprises a laminate film of retardation lower than 50 nm attached on said printed layer. The counterfeiting prevention device has high visibility of a latent image and durability.
摘要:
A transparent product that gives an image only at one side, which can be used for an advertisement on the window or the like, which is a product that has a semi-transmissive-half-reflective layer having transmittance of 30% or higher and a reflectance of 30% or higher, a birefringent layer which is a patterned optically anisotropic layer having two or more regions of different birefringence in the form of a pattern or a driven-type optically anisotropic layer containing a liquid-crystal compound driven by voltage application to control the optical anisotropy, and a polarizing layer in this order and does not have, at the opposite side of the polarizing layer with respect to the birefringent layer, a polarizing layer, is provided.
摘要:
A sewing machine includes an embroidery frame moving portion, a sewing portion, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, cause the processor to perform the steps of acquiring image data created by a device and obtained by capturing an image of a range that includes at least one reference mark and at least one indicator mark, computing positioning data based on the image data, specifying an embroidery pattern to be formed in a sewing workpiece clamped in an embroidery frame, setting at least one of a position and an angle of the embroidery pattern on the sewing workpiece, based on the positioning data, acquiring embroidery data, causing the embroidery frame moving portion and the sewing portion to form the stitches that make up the embroidery pattern in the sewing workpiece, based on the embroidery data.
摘要:
A sewing machine system includes a sewing machine and a storage device. The storage device includes an embroidery information storage portion, a conditions information storage portion, and a use history storage portion. The sewing machine includes a mounting portion to and from which the storage device can be mounted and removed, a first individual unit information storage portion that stores the first individual unit information, a use conditions determination portion that determines whether the sewing machine corresponds to the use conditions information, a usability determination portion that determines whether the embroidery information that is stored in the embroidery information storage portion can be used, a first decryption portion that decrypts the embroidery information, an individual unit information storage control portion that stores in the use history storage portion the first individual unit information, and an embroidery portion that performs embroidery sewing on a cloth.
摘要:
A sewing machine includes an embroidery frame moving portion, a sewing portion, a communication portion, a processor, and a memory. The memory is configured to store computer-readable instructions that cause the processor to perform the steps of specifying an embroidery pattern and a size of the embroidery pattern, outputting the size of the embroidery pattern through the communication portion to a device provided with an image capture portion, acquiring positioning data through the communication portion, setting at least one of a position and the angle of a embroidery pattern on a sewing workpiece based on the positioning data, acquiring embroidery data, and causing the embroidery frame moving portion and the sewing portion to form stitches that make up the embroidery pattern on the sewing workpiece based on the embroidery data. The positioning data have been computed by the device based on image data and output to from the device.
摘要:
A sewing data generating device includes a processor and a memory. The memory stores computer-readable instructions that instruct the sewing data generating device to execute steps including obtaining original image data of a pattern to be sewn on a work cloth, identifying a central line of the image, identifying a sewing start point and a sewing end point, and generating sewing data based on the sewing start point and the sewing end point. The sewing start point is one of a first point at which the central line and a contour line of the image intersect and a point separated from the first point. The sewing end point is one of a second point at which the central line and the contour line of the image intersect and a point separated from the second point. The second point is different from the first point.
