  • Publication number: 20210288504
    Abstract: The converter circuit includes an inverter. The converter circuit receives DC power from a DC power supply (such as a solar cell or a storage battery unit), has the DC power converted into AC power by at least the inverter, and outputs the AC power to a load or a power grid. When acquiring information that two or more types of power curtailment causes have arisen, a control circuit makes the converter circuit limit power output to a maximum degree of power curtailment out of two or more degrees of power curtailment according to specifics of the two or more types of power curtailment causes.

  • Publication number: 20210276458
    Abstract: A controller, which serves as a pressure-feeding control portion, drives an air pump to pressure-feed air to massage airbags located in a seat. In addition, the controller, which serves as an inflation-deflation control portion, performs massage control that inflates and deflates the airbags while keeping the air pump driven by controlling the operation of intake-discharge valves in second flow passage (branch lines), which connects the air pump to the airbags. Furthermore, the controller, which serves as a decompression control portion, opens a discharge valve, which is located upstream of the intake-discharge valves, in a state in which the airbags are deflated during the massage control.

  • Publication number: 20200211838
    Abstract: A technique for obtaining good film quality in forming a silicon-oxide-containing insulating film as a coating film on a substrate. A coating liquid containing polysilazane is applied to a wafer, a solvent in the coating liquid is volatilized, and then the coating film is irradiated with ultraviolet rays under a nitrogen atmosphere before performing a curing process. Thus, dangling bonds are likely to be formed at hydrolyzed portions in polysilazane. Since dangling bonds are formed in advance at portions in silicon to be hydrolyzed, productivity of hydroxyl groups is enhanced. That is, since an energy required for hydrolysis is reduced, the number of the portions remaining without being hydrolyzed is reduced even when the curing process is performed at a low temperature. Therefore, dehydration synthesis occurs efficiently, which increases a crosslinking rate and makes it possible to form a dense (good film quality) insulating film.

  • Patent number: 10196025
    Abstract: A seating detection method includes: detecting whether a seat belt sensor in a vehicle seat is in an ON state or an OFF state; detecting whether a pressure sensitive sensor in a seat skin constituting a seating surface is in an ON state or an OFF state; and determining a foreign object insertion state in which a foreign object is inserted between the seating surface and a child seat based on whether the seat belt sensor is in the ON state or the OFF state and whether the pressure sensitive sensor is in the ON state or the OFF state. When the pressure sensitive sensor is changed from the ON state to the OFF state in a state in which the seat belt sensor is maintained in the ON state after the seat belt sensor is changed to the ON state, it is determined as the foreign object insertion state.

  • Patent number: 10150489
    Abstract: A tubular elastic linkage device for axle beam for elastically linking a truck frame and an axle beam including: an inner axial member; two outer segments opposed in axis-perpendicular direction peripherally outside the inner axial member for attachment to a housing part on an axle-beam side; and a main rubber elastic body elastically connecting them. A pocket part opens in an outer peripheral face of the main rubber elastic body onto outside via a window penetrating one outer segment. A stopper supported by the inner axial member is disposed in the pocket part to face the housing part distantly via the window. Contact of the stopper with the housing part constitutes a displacement limitation mechanism between the inner axial member and the outer segments. The other outer segment has an aperture having the main rubber elastic body exposed outside via it.
