Publication number: 20240075410Abstract: There is provided a gas solution supply apparatus capable of preventing bubbles from being generated in use at a point-of-use even if gas solution to be provided to a point-of-use has a high concentration. The gas solution supply apparatus 1 includes: a gas dissolving unit 4 that dissolves a source gas in a source liquid to produce a first gas solution; a first gas-liquid separator 10 that stores the first gas solution produced and produces a second gas solution through gas-liquid separation of the first gas solution; a pressure reducer 17 that depressurizes the second gas solution produced in the first gas-liquid separator 10; and a second gas-liquid separator 12 that stores the depressurized second gas solution and produces a third gas solution through gas-liquid separation of the second gas solution. The third gas solution is supplied to a point-of-use.Type: ApplicationFiled: August 2, 2023Publication date: March 7, 2024Inventors: Suguru OZAWA, Yuji ARAKI, Yoichi NAKAGAWA, Toshifumi WATANABE, Risa KIMURA, Ryuta KATO

Patent number: 11321695Abstract: A monitoring device includes an interface circuit connectable to first and second readers. The first reader reads data from a tag attached to a commodity discarded within a predetermined area. The second reader reads data from a tag attached to a commodity taken out from the predetermined area. A processor is configured to, upon receipt of first data from the first reader, determine whether a tax rate is applied to a commodity to which a tag having the first data is attached, and upon determining that the rate is applied, store an identifier of the tag. The processor is configured to, upon receipt of second data from the second reader, determine whether an identifier of a tag having the second data is stored, and upon determining that the identifier is stored, issue a signal to output an alarm.Type: GrantFiled: February 15, 2021Date of Patent: May 3, 2022Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Suguru Kato

Publication number: 20190118570Abstract: A paper roll, in which a paper strip is wound in the form of a roll, includes a marker formed of a medium containing a phosphorescent material on an end portion of the paper strip that extends from a finishing end of the paper roll to a position that is a predetermined length from the finishing end. A printer includes a roller configured to convey paper supplied from the paper roll, a printing head configured to print information on the paper conveyed by the roller, one or more ultraviolet light emitting diodes (LEDs) positioned downstream of the printing head in a conveyance direction of the paper, and a control unit configured to turn on the LEDs to irradiate the paper on which the information has been printed and discharged out of the printer.Type: ApplicationFiled: October 10, 2018Publication date: April 25, 2019Inventor: Suguru KATO

Patent number: 10020637Abstract: To improve characteristics of a semiconductor device (semiconductor laser), an active layer waveguide (AWG) comprised of InP is formed over an exposed part of a surface of a substrate having an off angle ranging from 0.5° to 1.0° in a [1-1-1] direction from a (100) plane to extend in the [0-1-1] direction. A cover layer comprised of p-type InP is formed over the AWG with a V/III ratio of 2000 or more. Thereby, it is possible to obtain excellent multiple quantum wells (MQWs) by reducing a film thickness variation of the AWG. Moreover, the cover layer having side faces where a (0-11) plane almost perpendicular to a substrate surface mainly appears can be formed. A sectional shape of a lamination part of the cover layer and the AWG becomes an approximately rectangular shape. Therefore, an electrification region can be enlarged and it is possible to reduce a resistance of the semiconductor device.Type: GrantFiled: June 1, 2017Date of Patent: July 10, 2018Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Satoshi Ae, Shoutarou Kitamura, Tetsuro Okuda, Suguru Kato, Isao Watanabe
