  • Patent number: 11614651
    Abstract: A liquid crystal device includes a reflection-type liquid crystal panel in which a first substrate provided with a reflective layer and a second substrate having light-transmissivity face each other via a liquid crystal layer. In the liquid crystal device, a ?/4 phase difference plate is arranged in an optical path in which light incident from the second substrate side is reflected by the reflective layer and emitted from the second substrate side, and a phase difference compensation layer such as a C plate and O plate provided integrally with the liquid crystal panel is provided in the optical path. The ?/4 phase difference plate is an inorganic material film provided on a second end surface facing the second substrate in the polarized light separating element. The phase difference compensation layer is an inorganic material film provided on a surface of the second substrate opposite to the liquid crystal layer.

  • Patent number: 11041649
    Abstract: Change of a set room temperature of an air-conditioning apparatus leads to change of electric power consumed by the air-conditioning apparatus, and in a case of cooling, the consumed electric power increases as the set room temperature decreases. Consequently, a user has been unable to freely change the set room temperature. Thus, when the set room temperature is changed by the user, an evaporating temperature (refrigerant temperature) at which the electric power consumed by the air-conditioning apparatus does not change before and after the change is estimated and the air-conditioning apparatus is commanded for the evaporating temperature, which allows the user to pursue indoor comfort without worrying about the electric power consumed by the air-conditioning apparatus.

  • Patent number: 10932753
    Abstract: According to an embodiment, a transmitter transmits a reference signal. A position sensor obtains position information in a three-dimensional space by receiving the reference signal. A controlling unit associates three-dimensional image data generated by a medical image diagnosis apparatus with the three-dimensional space, on the basis of a registration between an arbitrary cross-sectional plane in the three-dimensional image data and a cross-sectional plane scanned by an ultrasound probe. A detecting unit detects if the position of the transmitter has changed within the associated three-dimensional space, on the basis of the position information obtained by the position sensor. A correcting unit corrects a misregistration between a cross-sectional plane in the three-dimensional image data and a cross-sectional plane scanned by the ultrasound probe, on the basis of a change amount of the position of the transmitter.
