  • Publication number: 20220275264
    Abstract: [Object] This invention, on an assumption that the environmental situation must be considered, reduces the brake noise, prevents the reduction of the braking effectiveness in the high temperature range, and improves the wear resistance. [Means to Resolve] In the NAO friction material composition that does not practically contain a copper component, this invention contains the first substance made of such as the calcium carbonate that is the substance which becomes the sintered body during braking and is the precursor of the sintered body which keeps the powder generated from the disc rotor, and the second substance made of such as the fluoropolymer that is the sintering additive which aids sintering of the first substance.

  • Patent number: 9863680
    Abstract: An apparatus includes a refrigerant circuit in which a compressor that compresses a refrigerant, an indoor-side heat exchanger serving as a radiator that exchanges heat between the refrigerant and a heating target, an expansion valve that decompresses the refrigerant by opening-degree adjustment, and an outdoor-side heat exchanger serving as an evaporator that exchanges heat between a heat-exchange target and the refrigerant are connected by pipes. The apparatus includes: an outdoor air temperature sensor that detects a temperature of outdoor air serving as the heat-exchange target; a discharge-side temperature sensor that detects a discharge temperature of the refrigerant discharged by the compressor; and a controller that, when the controller determines that a rotation speed of the compressor is a maximum and the temperature of the heat-exchange target is lower than a preset temperature, controls an opening degree of the expansion valve by using the discharge temperature.

  • Patent number: 9070485
    Abstract: In a reactor vessel (20) covered by cooling water (2), a tubular frame (10) with a bottom is hung within the cooling water (2) while still having an air environment in the interior, and the bottom section of the frame (10) is disposed within the reactor vessel (20), thereby achieving an air environment within the reactor vessel (20). Furthermore, since repairs to the reactor vessel (20) are performed by using the frame (10) while still having the air environment in the interior, this leads to the prevention of contamination and achieves improvements in working conditions such as preventing the generation of dust and reducing decontamination work. Accordingly, repairs can be performed in an air environment without draining the cooling water (2) within the reactor vessel (20), even in a state in which the reactor vessel (20) is covered by the cooling water (2).
