  • Publication number: 20190107416
    Abstract: An encoder signal processing device, a printer, a printer-equipped imaging apparatus, and an encoder signal processing method that can remove the effect of a noise signal mixed with an encoder signal and favorably deal with a case where an original pulse signal is lost from the encoder signal are provided. An effective detection period setting unit 523 sets an effective detection period for detecting a subsequent pulse signal, each time a pulse signal detection unit 522 detects a pulse signal from an encoder signal. The pulse signal detection unit 522 detects the pulse signal only within the set effective detection period. In a case where the pulse signal detection unit 522 does not detect the pulse signal within the effective detection period, a pulse signal generation unit 524 generates the pulse signal after the effective detection period.

  • Publication number: 20190084317
    Abstract: A pulse signal is detected from an encoder signal of a rotary encoder. The detected pulse signal is used as a signal for controlling a light exposure timing of a line type light exposure head and is used for detecting a transport speed of an instant film. The light exposure head sequentially performs light exposure for a line image on the transported instant film in synchronization with each pulse signal detected from the encoder signal, and a density correction unit corrects an amount of light emission of the light exposure head depending on the transport speed of the instant film.

The n+-type cathode region and the p-type cathode region constitute a cathode layer and are adjacent to each other along a direction parallel to the rear surface of the semiconductor substrate. The n+-type cathode region and the p-type cathode region are in contact with a cathode electrode. In an n?-type drift layer, plural n-type FS layers are provided at differing depths deeper from the rear surface of the semiconductor substrate than is the cathode layer. With such configuration, in a diode, a tradeoff relationship of forward voltage reduction and reverse recovery loss reduction may be improved and soft recovery may be realized.
