  • Patent number: 11735139
    Abstract: A display-system includes a transparent-display-body having a first-surface and a second-surface opposite to the first-surface, a sensor to detect a brightness of the transparent-display-body or a brightness around the transparent-display-body, an arithmetic-unit configured to derive, based on the brightness detected by the sensor, a background luminance caused by outside-light as when the transparent-display-body is viewed from a side of the second-surface, and a controller to cause video to be displayed on the first-surface, wherein where rear-show-through-luminance that is a luminance of the video that occurs on the side of the second-surface is denoted as BB and the background luminance is denoted as SB, the controller controls a video luminance in accordance with the background luminance derived by the arithmetic-unit such that (BB/SB) is less than or equal to a predetermined-contrast-value, the video luminance being a luminance at which the video is to be displayed on the first-surface.

  • Publication number: 20230234427
    Abstract: A laminated glass includes first and second glass plates. First and second interlayers are arranged on the first and second glass plates, respectively. The first and second glass plates are arranged so as to have the first and second interlayers face each other. An enclosing layer is arranged between the first and second interlayers. The enclosing layer includes a functional member having a sidewall, and a dummy layer arranged on the sidewall, the functional member including one or more transparent layers. The functional member has a thickness of 200 ?m at a maximum. The dummy layer is made of a thermoplastic resin. When denoting an average refractive index of the transparent layers included in the functional member as nA, and denoting a refractive index of the dummy layer as nB, a difference ?n of the refractive indices expressed by an absolute value |nA?nB| is 0.05 or less.

  • Patent number: 10456433
    Abstract: Provided are an inhibitor, a prophylactic, and a therapeutic agent for rheumatoid arthritis that have no side effects and that can correct immune abnormality associated with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent for rheumatoid arthritis contain a Euglena-derived material as an active ingredient. The inhibitor, the prophylactic and the agent are used as an antirheumatic drug for controlling the activity of rheumatoid arthritis by alleviating immune abnormality associated with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent are also used for a living individual who has not been definitively diagnosed with rheumatoid arthritis. The inhibitor, the prophylactic, and the agent are continuously administered to the living individual from any point before definitive diagnosis of rheumatoid arthritis to any point after the definitive diagnosis.

  • Patent number: 10231989
    Abstract: Provided are a novel renal failure progression inhibitor, prophylactic agent for renal failure, and indoxyl sulfate production inhibitor, intended for human use, in particular, for a patient with renal failure. The renal failure progression inhibitor, prophylactic agent for renal failure, and indoxyl sulfate production inhibitor each comprises paramylon derived from Euglena or a processed product thereof as an active ingredient. In the case of the renal failure progression inhibitor, for example, paramylon is continuously orally administered to a patient suffering from chronic renal failure, undergoing a dialysis therapy, several times per day in a dose of 1 to 5 g per intake. In particular, the renal failure progression inhibitor is singly administered to the patient in a capsule or powdered preparation at a prescribed time interval before and after administration of other drugs.

  • Publication number: 20170020939
    Abstract: The present invention provides a novel immune balance regulator that regulates an immune balance in a living body. The immune balance regulator contains a Euglena-derived material and regulates an immune balance between Th1, Th2, and Th17, which is a balance between immune responses individually induced by Th1, Th2, and Th17 in a living body. The immune balance regulator regulates the immune balance between Th1, Th2, and Th17 so that immune responses induced by Th1 become relatively dominant over immune responses induced by Th2 or Th17 to improve a physical constitution that has an immune imbalance of Th1, Th2, and Th17 shifted towards Th2 and to prevent or treat a disease associated with the immune imbalance of Th1, Th2, and Th17 shifted towards a Th2 dominance. The immune balance regulator is administered prior to expected onset of a disease associated with the immune imbalance of Th1, Th2, and Th17 shifted towards the Th2 dominance.

  • Patent number: 7231346
    Abstract: A speech section detection apparatus capable of reliably detecting a speech section even for a word containing a glottal stop sound or for a word containing a succession of “s” column sounds or “h” column sounds (sounds in the third column or the sixth column in the Japanese Goju-on Zu syllabary table). A speech signal detected by a microphone is amplified by a line amplifier, and converted by an analog/digital converter into a digital signal which is then stored in a memory. The stored speech signal is fetched into a pitch detector where a speech pitch is extracted by processing the speech signal in time domain. A gate signal generator controls the gate signal based on the speech pitch, and a speech section signal generator controls a speech section signal based on the gate signal. A word can be extracted by segmenting the speech signal stored in the memory in accordance with the speech section signal.

  • Publication number: 20050015244
    Abstract: A speech section detection apparatus capable of reliably detecting a speech section even in the case of a speech signal with low signal-to-noise ratio. The speech signal collected by a microphone and amplified by a line amplifier is converted by an A/D converter into a digital value, which is then stored in a memory. After removing noise from the digitized speech signal, the signal-to-noise ratio is improved by taking short-time auto-correlation and, when the signal level has continued to stay above a threshold value for a predetermined period, it is determined that a speech section has been detected. Further, a prescribed period before and after the thus determined speech section is also forcefully set as a target for extraction so that the beginning and end of the speech section can be reliably detected.
