Patent number: 11927356Abstract: An air conditioning apparatus includes a plurality of third heat exchangers and flow rate control valves. In a heating mode, a controller opens a flow rate control valve corresponding to a heat exchanger that is being requested to perform air conditioning of the plurality of third heat exchangers, and closes a flow rate control valve corresponding to a heat exchanger that is not being requested to perform air conditioning of the plurality of third heat exchangers. In a defrosting mode, when a temperature of a second heat medium is lower than a first determination temperature, the controller opens a flow rate control valve corresponding to at least one of the heat exchangers that are not being requested to perform air conditioning. The at least one of the heat exchangers is assigned a higher priority than a remaining heat exchanger that is not being requested to perform air conditioning.Type: GrantFiled: April 18, 2019Date of Patent: March 12, 2024Assignee: Mitsubishi Electric CorporationInventors: Naoki Kato, Yuji Motomura, Kimitaka Kadowaki

Patent number: 11930601Abstract: A method for manufacturing a printed wiring board includes forming a seed layer on a surface of a resin insulating layer, applying a dry film onto the seed layer using a laminating roll device, cutting the dry film applied onto the seed layer to a predetermined size, applying pressure and heat to the dry film, forming a plating resist on the seed layer from the dry film using photographic technology, forming an electrolytic plating film on part of the seed layer exposed from the resist, removing the resist from the seed layer, and removing the part of the seed layer exposed from the electrolytic plating film. The applying of the pressure and heat includes applying the pressure and heat to the dry film applied onto the seed layer such that the pressure and heat are applied to the entire surface of the dry film cut to the predetermined size simultaneously.Type: GrantFiled: February 24, 2022Date of Patent: March 12, 2024Assignee: IBIDEN CO., LTD.Inventors: Yuji Kadowaki, Tomomi Kano

Patent number: 8877310Abstract: The invention discloses a multilayer propylene resin sheet and a heat-treatable packaging material which have an excellent transparency, flexibility and very-low-temperature impact resistance, and which reduce the thickness variation during lamination, suppress appearance defects such as interfacial roughness and mitigate thinning during fabrication. The multilayer propylene resin sheet is composed of at least two layers, which are (1) an inner layer and (2) an outer layer. The inner layer (1) is made of a resin composition containing 40 to 89 wt % of a specific propylene resin composition (A), 10 to 40 wt % of a specific ethylene-?-olefin copolymer (B), and 1 to 20 wt % of a specific propylene resin (C). The outer layer (2) is made of a specific propylene resin composition.Type: GrantFiled: September 8, 2011Date of Patent: November 4, 2014Assignee: Japan Polypropylene CorporationInventors: Gen Kanai, Yuji Kadowaki
