  • Publication number: 20210108805
    Abstract: An outdoor-heat-exchanger ventilation channel definer defines an outdoor-heat-exchanger ventilation channel in which an outdoor heat exchanger is located. The outdoor-heat-exchanger ventilation channel definer has a first outdoor-heat-exchanger inlet, an outdoor-heat-exchanger outlet, and a second outdoor-heat-exchanger inlet. The first outdoor-heat-exchanger inlet and the outdoor-heat-exchanger outlet each are connected to an exterior space. The second outdoor-heat-exchanger inlet is connected to a target room. An outdoor fan creates an airflow in the outdoor-heat-exchanger ventilation channel. The airflow includes outdoor air in the exterior space drawn through the first outdoor-heat-exchanger inlet and indoor air in the target room drawn through the second outdoor-heat-exchanger inlet, passing through the outdoor heat exchanger, and discharged to the exterior space through the outdoor-heat-exchanger outlet.

  • Patent number: 10337626
    Abstract: In a heating medium channel switching device, a valve body whose interior is partitioned into two channels by a partition plate is axially rotated by a motor, whereby a relative position of the valve body in a valve chamber is controlled. Because of this, one of a first heating medium and second heating medium can be selected and caused to flow out in one channel, and one of a third heating medium and fourth heating medium can be selected and caused to flow in the other channel. Also, heating medium flow can be controlled by an angle of rotation of the valve body being controlled.

  • Patent number: 7907505
    Abstract: A code disk for a high-resolution encoder that can detect an absolute position and a method for manufacturing a mold to produce the code disk are provided. The code disk is formed by using transparent substrate. The code disk includes a plurality of tracks provided on the transparent substrate and an area provided between the plurality of tracks. Each surface of the plurality of tracks has a different pattern. A level of the area is different from that of the each surface of the plurality of tracks. The method for manufacturing the mold includes steps of processing a plurality of tracks with a flat surface on material; processing an area with a level different from that of each surface, between the plurality of tracks; forming different patterns on the each surface; plating the first material; and peeling plating from the first material to obtain a mold.

  • Publication number: 20100272932
    Abstract: In a conventional decorative component, a conductive material is formed on the entire surface of an insulation part so that the decoration part looks in metallic color. However, an electric current flows through the inside of the conductive material, and hence electromagnetic waves applied to the decoration part suffers a loss. This poses a problem that sufficient antenna characteristics cannot be obtained. On the member surface, a semiconductor layer or a semi-metal layer with a film thickness of 5 nm or more, and a mean transmittance of 65% or less and a mean reflectance of 20% or more at 400 nm to 800 nm is formed. This can implement a decorative component exhibiting a sufficient metallic luster without blocking the electromagnetic waves.
