  • Publication number: 20210265184
    Abstract: A communication method of a transport system including transport carriages each transporting a transported object, and communication devices connected one-to-one with loading ports onto which the transported objects are loaded. The communication devices are communicably connected to each other in advance. The communication method includes transmitting, from a specific transport carriage to the communication devices, a first signal having a specific communication as a final transmission destination, and receiving, in the specific communication device, the first signal from the specific transport carriage through a communication channel that passes through another communication device. The first signal is a signal communicated for the specific transport carriage to transfer the transported object to and from a specific loading port connected one-to-one with the specific communication device.

  • Patent number: 10324249
    Abstract: A display device includes a prism sheet between a display cell and a light guiding plate. The prism sheet includes a plurality of prisms having a constant apex angle continuously arranged in a second direction on a surface thereof opposed to a light-exiting surface of the light guiding plate. Each of ridge lines of the prisms extends in a first direction. Each prism has a first inclined face on a side on which light from the light guiding plate is incident and a second inclined face on a side reflecting the incident light. An area of the first inclined face is made smaller than an area of the second inclined face, and an area of a light-emitting region in the prism sheet is made larger than an area of a non-light-emitting region.

  • Patent number: 8773630
    Abstract: A display panel includes a bonded substrate which is bonded with a seal portion having an inlet portion, in which an inlet of a fluid is formed, a sealing material which seals the inlet, metal film patterns which are provided in an end portion of the bonded substrate, and external connection terminals which respectively have rectangular base portions and are provided in parallel in a transverse direction of the base portion. Each metal film pattern has a rectangular pattern base portion. The metal film patterns are provided in parallel such that the center position of the pattern base portion in the transverse direction is aligned with the center position of the base portion in the transverse direction. The width of the pattern base portion in the transverse direction is equal to or smaller than the width of the base portion in the transverse direction at the same arrangement position.

  • Patent number: 8767146
    Abstract: A display device is provided which includes a lower substrate and an upper substrate. An inner surface of the lower substrate and an inner surface of the upper surface face each other. A polarizing plate is disposed on an outer surface of the upper substrate, wherein the polarizing plate includes at least an inside protective film, a polarizing film and an outside protective film, which are layered on the upper substrate side in this order so that the inside protective film is adjacent to the upper substrate. An expansion axis of the outside protective film forms an angle of 30° or more and 90° or less with an expansion axis of the polarizing film, and an expansion axis of the inside protective film forms an angle of 0° or more and 3° or less with an expansion axis of the polarizing film.
