  • Publication number: 20200080189
    Abstract: A flow resistant part having a rod shape is disposed in a raw liquid introduction path in a manner such that the raw liquid is sprayed onto a vaporization plate to reduce the conductance of the raw liquid introduction path with respect to the raw liquid. Because the pressure on an outlet side of the liquid mass flow controller is increased, and the pressure difference from the pressure on the inlet side of the liquid mass flow controller is reduced, the occurrence of cavitation can be prevented. A plurality of the flow resistant parts can be provided.

    Abstract: A split unit capable of providing a stereoscopic image having less laterality is provided. The split unit includes: a beam splitter which transmits first imaging light as a part of light incident on an incident surface of the beam splitter, and reflects second imaging light as another part of the light incident on the incident surface; and a reflecting member which reflects the second imaging light reflected by the beam splitter. At least one of a reflectance of the reflecting member and a beam splitting characteristic of the beam splitter is set based on the following formulae: T=d/(1+d) R=1?T where T (0?T?1) is a transmittance of the beam splitter, R (0?R?1) is a reflectance of the beam splitter, and d (0?d?1) is a reflectance of the reflecting member.

  • Patent number: 8675979
    Abstract: A transcoder reduces the processing amount when a coded stream to which at least intra prediction is applied is transcoded into a coded stream to which intra prediction and inter prediction are applied. The transcoder converts a first coded stream to at least part of which intra prediction is applied, into a second coded stream to which intra prediction and inter prediction are applied. The transcoder includes a decoding unit that decodes the first coded stream to generate decoded image data; a prediction mode obtaining unit that obtains a prediction mode of intra prediction applied in decoding; and a coding unit that codes the decoded image data by applying the intra prediction or inter prediction to generate the second coded stream. A control unit controls causes the coding unit to use the prediction mode obtained by the prediction mode obtaining unit when the coding unit applies intra prediction.
