  • Publication number: 20220178050
    Abstract: Electromagnetic waves are uniformly distributed on the light-receiving surface side by taking advantage of their property of being easily concentrated in sharp parts, and the front area (SA) on the emission surface side is made larger than the back area (SB) on the light-receiving surface side (SA/SB>1), thereby forming a more moderate electric field region. A reduced gold fine particle group (average particle size: 20 nm) was self-assembled on a transparent polyester resin film and half-submerged and fixed. This base material was repeatedly immersed in an electroless gold plating solution so that gold particles were deposited on the gold fine particles. 10 microliters of a protein solution was added dropwise to this nanostructured substrate, and crystallized by a hanging drop vapor diffusion method.

  • Patent number: 11353234
    Abstract: Each of plural temperature adjustment apparatuses variably adjusts the amount of heat exchange between an inflow medium, which is a liquid medium supplied to a corresponding indoor heat exchanger, and an outflow medium, which is a liquid medium discharged from the corresponding indoor heat exchanger. Each of the plural temperature adjustment apparatuses reduces the heat exchanging capacity of the corresponding indoor heat exchanger by increasing the amount of heat exchange between the inflow medium and the outflow medium when the heat exchanging capacity of the corresponding indoor heat exchanger is larger than the indoor load. When there is no temperature adjustment apparatus in which the amount of heat exchange between the inflow medium and the outflow medium is set to the minimum, the heat source apparatus reduces the heating capacity or the cooling capacity for changing the temperature of the liquid medium.

  • Patent number: 11333366
    Abstract: A temperature adjustment apparatus adjusts a temperature of a heating medium that exchanges heat with air in an indoor heat exchanger connected to a heat source apparatus. It includes a first and second pipes through which the heating medium flows, the second pipe being branched into a first and second branch pipes which are thereafter merged, a second heat exchanger in which heat is exchanged between the heating medium in the first branch pipe and the heating medium in the first pipe, and a flow rate regulator that changes a flow rate of the heating medium in the first branch pipe and a flow rate of the heating medium in the second branch pipe. The second pipe supplies the heating medium from the heat source apparatus to the indoor heat exchanger. The first pipe returns the heating medium from the indoor heat exchanger to the heat source apparatus.

  • Publication number: 20220145470
    Abstract: A nanostructure substrate includes groups of composite particles in which a reduced and deposited coating layer shows cohesive polarization action and/or electromagnetic polarization action. Also, to provide a nanostructure substrate, such active sites are dramatically increased to allow a medium to react homogenously over the entire nanostructure substrate. On a transparent semi-curable polyester resin film, groups of gold fine particles (average particle diameter: 20 nm) are reduced and deposited from an aqueous solution and self-aggregated. A half of the lower part of the groups of gold fine particles is submerged in the polyester resin film, and embedded in the front surface side of the transparent resin base body. Then, this transparent substrate is immersed in an electroless gold-plating solution repeatedly to deposit gold crystal grains on the fixed groups of gold fine particles.

  • Publication number: 20210328239
    Abstract: A fuel cell system includes a fuel cell stack and a control device that controls operation of the fuel cell system based on a measured voltage value measured by a voltage sensor. When the fuel cell system is started and a value measured by a temperature sensor is equal to or less than a temperature determined in advance, the control device raises the voltage of the fuel cell stack until a voltage condition determined in advance is met, by supplying a cathode with an oxidant gas before current sweep is started. The control device sets a voltage command value and a current command value such that an operation point of the fuel cell stack is on an equal power line of the fuel cell stack when the operation point is caused to transition in at least a part of a transition period.
