  • Patent number: 10867729
    Abstract: Provided is a method for producing a sintered body that forms a rare-earth permanent magnet, has a single sintered structure and an arbitrary shape, and has easy magnetization axis orientations of different directions applied to the magnet material particles in a plurality of arbitrary regions. This method forms a three-dimensional first molded article from a composite material formed by mixing a resin material and magnet material particles containing a rare-earth substance. The first molded article is then subjected to a deforming force and a second molded article is formed in which the orientation direction of the easy magnetization axis of the magnet material particles in at least the one section of the horizontal cross-section is changed to a direction which differs from the orientation direction of the first molded article. The second molded article is heated to a sintering temperature and kept at the temperature for a period of time.

  • Publication number: 20200347929
    Abstract: A transmission controller of a toroidal continuously variable transmission includes a gain setting unit that adjusts a gain of closed-loop control for calculating a target value of a roller position in accordance with a change in a rotation speed of a disc in a first rotation speed range and a second rotation speed range higher than the first rotation speed range. The gain setting unit changes, in the first rotation speed range, the gain so that sensitivity of the closed-loop control decreases with an increase in the rotation speed, and changes, in the second rotation speed range, the gain so that a rate of decrease in the sensitivity of the closed-loop control with the increase in the rotation speed is smaller than that in the first rotation speed range.

  • Publication number: 20190265357
    Abstract: An electromagnetic wave from a transmitter (100) is emitted toward the outside of a first angular range (AR). A receiver (200) cannot detect an electromagnetic wave reflected at a position somewhat close to a sensor device (10), specifically, an electromagnetic wave reflected at a position apart from the sensor device (10) by less than a distance R1. Specifically, when the electromagnetic wave is reflected at the position apart from the sensor device (10) by less than the distance R1, the electromagnetic wave reaches the sensor device (10) before the first angular range (AR) reaches a Y axis. Consequently, the electromagnetic wave reflected at the position somewhat close to the sensor device (10) is not detected by the receiver (200).

    Abstract: A blood purifier comprises hollow fiber membranes allowing a dialysing fluid or a filtrated fluid to flow outside. The membrane has an effective length of 10 mm or more and 150 mm or less. A maximum value of a permeation flux Jv obtained by dividing a volume of a permeate fluid permeating through the membranes by a membrane area of the hollow fiber membranes and time, is represented as Jvmax. A linear velocity of blood flowing in the membrane is represented as uB. A pressure difference between blood flowing inside the membranes and a fluid flowing outside the membranes is represented as TMP. When a filling blood volume into the membranes per unit membrane area is 20 mL/m2 or more and 35 mL/m2 or less and Jvmax/uB has a value of 0.00015 or more and 0.0006 or less, a TMP change rate is 0.95 or more and 1.05 or less.

  • Patent number: 7738525
    Abstract: A semiconductor laser (101) includes a first cladding layer (103), an active layer (105) and a second cladding layer (108). A window region (115) including fluorine, that is, an impurity element with higher electronegativity than nitrogen, is formed in the vicinity of a front end face (113) and a rear end face (114) of a laser resonator. The window region (115) is formed by exposing the front end face (113) and the rear end face (114) to carbon fluoride (CF4) plasma. The effective band gap of a portion of the active layer (105) disposed in the window region (115) is larger than the effective band gap of another portion of the active layer, and hence, it functions as an end face window structure for suppressing COD.
