The present invention involves using mechanized strategies to fabricate test samples as well as strategies for selecting sample substrates. In some cases this is accomplished using a write buffer to store random writes. Polarizers that polarize lights which have passed therethrough into linear polarized lights whose vibration planes are orthogonal to each other are fitted into those two openings. A matching unit is configured to perform impedance matching between the antenna and an NFC chip. The rectifier is electrically connected between the conductive electrode and the developer roller. A lead frame having a resin film mounted thereon is mounted on the heat plate, and thin metal wires are respectively connected to the half-etched portions of the first signal connection leads.
