Publication number: 20210288504Abstract: 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.Type: ApplicationFiled: June 19, 2019Publication date: September 16, 2021Inventors: Wataru HORIO, Hiroyuki FUJII, Kenji HANAMURA, Kota MAEBA

Publication number: 20200211838Abstract: 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.Type: ApplicationFiled: March 13, 2018Publication date: July 2, 2020Inventors: Makoto MURAMATSU, Yusuke SAITO, Hisashi GENJIMA, Hiroyuki FUJII
