A polyhedron disposable container formed from flexible weldable plastic film is provided. According to present invention, the domain input process can be simpler as the user has only to input number domain corresponding to homepage to be connected and press execution button. Other embodiments including additional apparatuses and methods are described. Then, the light returning to the refractive diffraction grating 13 is reflected to an incident direction of the original light. Therefore, when the first device is used with a second device, integrated circuit or logic, which can handle the serial data in only one order, the first device is programmed, or configured, to handle the serial data in the same order as the second device.
