  • Publication number: 20230280678
    Abstract: An image forming apparatus includes a photoconductor; a charger, an exposure device, a developing device, a transferor, a cleaner, a belt resistance sensing device, and a transfer bias applier. The charger charges a surface of the photoconductor with a charge of a single polarity. The exposure device irradiates the surface of the photoconductor with light after charging. The developing device supplies a developer to the surface of the photoconductor. The transferor transfers an image developed by the developing device, from the surface of the photoconductor onto an intermediate transfer belt. The cleaner cleans the developer remaining on the surface of the photoconductor after an image transfer by the transferor. The sensing device is provided for the transferor, to detect a resistance value from a current value flowing during application of a transfer bias. The bias applier controls, according to the resistance value detected, the transfer bias applied to the transferor.

  • Publication number: 20230109867
    Abstract: A speech recognition apparatus (2000) acquires source data (10) representing an audio signal including an utterance. The speech recognition apparatus (2000) converts the source data (10) into a text string (30). The speech recognition apparatus (2000) generates a concatenated text (40) representing a content of an utterance by concatenating a text (32) included in the text string (30). Herein, texts (32) adjacent to each other in the text string (30) are such that parts of associated audio signals overlap each other on a time axis. At a time of concatenating texts (32) adjacent to each other, the speech recognition apparatus (2000) eliminates a trailing portion of a preceding text (32) and a leading portion of a succeeding text (32).

  • Patent number: 11626568
    Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk, resistance of a laterally conductive OLED layer may be increased. The laterally conductive layer may include an organic host material, dopants, and a resistance-increasing additive. Another way to reduce leakage current is to apply bias voltages to the anodes of the display and/or expose the laterally conductive layer to ultraviolet light, causing dopants within the laterally conductive layer to degrade.

  • Publication number: 20230066066
    Abstract: A medical sheet has a cell infiltration suppressing action, including a nonwoven fabric formed of fiber containing an aliphatic polyester, and having a porosity of 50 to 90%. The sheet is very useful because it has an excellent neuroprotective and/or nerve regeneration promoting action, which protects nerves by suppressing the infiltration of inflammatory cells such as macrophages and not giving stimulation that adversely affects nerves because body fluids pass therethrough, by winding around a nerve at a peripheral nerve injury site.

  • Publication number: 20230046763
    Abstract: A speech recognition apparatus (2000) includes a first model (10) and a second model (20). The first model (10) is learned by training data with an audio frame as input data, and with, as correct answer data, compressed character string data acquired by encoding character string data represented by the audio frame. The second model (20) is a learned decoder (44) acquired by learning an autoencoder (40) being constituted of an encoder (42) converting input character string data into compressed character string data, and the decoder (44) converting, into character string data, the compressed character string data output from the encoder. The speech recognition apparatus (2000) inputs an audio frame to the first model (10), inputs, to the second model (20), compressed character string data output from the first model (10), and thereby generates character string data corresponding to the audio frame.
