  • Patent number: 10428889
    Abstract: A torsion spring that is used in a throttle valve device increasing and decreasing an opening degree of an intake passage or an exhaust passage of an internal-combustion engine includes: two coil springs connected with each other so that torsion directions are opposite from each other; and a hook disposed between the two coil springs. Of the two coil springs, one side spring arranged at one side in an axial direction biases a valve object to a closing side, and the other side spring arranged at the other side in the axial direction biases the valve object to an opening side. In at least one coil spring of the two coil springs, a dimension of a clearance between the at least one coil spring and the hook connected with each other is larger than an average value of clearances between coil turns of the at least one coil spring.

  • Publication number: 20190283537
    Abstract: An electronic control unit is applied to an air conditioner, the air conditioner including a heating unit which heats a heat medium, a casing which allows an air flow to circulate toward a compartment, a blower which generates the air flow in the casing, and a heat exchanger disposed in the casing that heats the air flow by exchanging heat between the heat medium heated by the heating unit and the air flow. The blower air volume of the blower is controlled based on a first candidate value determined based on an estimated blowing temperature, and a second candidate value determined based on a required blowing air temperature and the estimated blowing temperature. The second candidate value is set as a predetermined value when a warm-up operation of the heating unit is completed.

  • Publication number: 20190038206
    Abstract: [Problem] To provide a masticatory-function evaluation and management system capable of quickly counting “fine particles having been not crushed and ground finely” and quickly quantifying masticatory efficiency using photographic data of an artificial food mass in a stretched state, and capable of managing the masticatory efficiency quantified using such an artificial food mass for masticatory function evaluation along the time series. [Solution] When image data of an artificial food mass, in a stretched state, for masticatory function evaluation is received, the image data being transmitted from a user terminal, the number of fine particles having a spherical shape is counted from among all fine particles present in the image data, and masticatory efficiency is calculated on the basis of the number of the fine particles having the spherical shape.

  • Publication number: 20180305650
    Abstract: A culture bag includes a culture portion which has a culture space configured to contain and culture a culture fluid. The culture space is an endless circumferential circulation space in which the culture fluid can circumferentially circulate. The culture fluid can continue to circumferentially circulate in one direction in the endless culture space. This suppresses complexification of flow of the culture fluid. As a result, bubbles can be suppressed from generating without decreasing culture efficiency.
