  • Patent number: 11978766
    Abstract: Three-dimensional capacitive structures may be produced by forming a capacitive stack conformally over pores in a region of porous anodic oxide. The porous anodic oxide region is provided on a stack of electrically-conductive layers including an anodization-resistant layer and an interconnection layer. In the pores there is a position having restricted diameter quite close to the pore bottom. In a first percentage of the pores in the region of anodic oxide, a functional portion of the capacitive stack is formed so as to extend into the pores no further than the restricted-diameter position. Cracks that may be present in the anodization-resistant layer have reduced effect on the properties of the capacitive structure. Increased thickness of the anodization-resistant layer can be tolerated, enabling equivalent series resistance of the overall capacitive structure to be reduced.

  • Patent number: 11879677
    Abstract: An air-conditioning apparatus includes a load-side heat exchanger including a first heat exchanger disposed on a windward of a second heat exchanger in a direction of an air flow generated by an air-sending device. The air flow passing through the first heat exchanger passes through a second heat exchanger. During cooling operation, a bypass valve causes a part of refrigerant flowing through a first refrigerant pipe to flow through a coupling pipe through a bypass pipe. During heating operation, the bypass valve blocks a flow of the refrigerant flowing from the coupling pipe toward the first refrigerant pipe through the bypass pipe, and causes all of the refrigerant flowing through the coupling pipe to flow from the coupling pipe to the first heat exchanger.

  • Publication number: 20230008510
    Abstract: A state detection system includes a server and an apparatus. The apparatus includes one or more internal devices, a first control module, a determination module, a first storage module, and a first communication module. The control module acquires signal information from each internal device. The determination module refers to a first database in the storage module and determines a state of the apparatus from the signal information. The communication module transmits the result of determination and/or the signal information to the server. The server stores a second database for determination of the state of the apparatus. The server determines the state of the apparatus based on the determination result and/or the signal information from the apparatus. The server makes a notification indicating information based on the determination result, transmits data in the second database to the apparatus, and causes the apparatus to update the first database.

  • Publication number: 20220241485
    Abstract: An objective of the present invention is to a suction bottle or a thrombus aspirator having a novel structure capable of solving at least one of the problems inherent in conventional suction bottles such as allowing a practitioner to quickly and easily confirm the presence of a thrombus in the suctioned blood, being able to easily separate the suctioned blood and thrombus, and being able to make the bottle compact to facilitate handling. The suction bottle (10) for a thrombus aspirator is equipped with a thrombus trapping member (82) that spreads so as to separate the inside of the bottle into an upper region (78) and a lower region (80). The thrombus trapping member (82) is provided with a plurality of through-holes (88) that cause blood guided to the upper surface to flow down from the upper region (78) to the lower region (80).
