Publication number: 20240097394Abstract: A light emitting sealed body includes: a housing which stores a discharge gas and is provided with a first opening to which first light is incident along a first optical axis and a second opening from which second light is emitted along a second optical axis; a first window portion which hermetically seals the first opening; and a second window portion which hermetically seals the second opening. The housing is formed of a light shielding material which does not transmit the first light and the second light. An internal space is defined by the housing, the first window portion, and the second window portion and the internal space is filled with the discharge gas. The first opening and the second opening are disposed so that the first optical axis and the second optical axis intersect each other.Type: ApplicationFiled: November 27, 2023Publication date: March 21, 2024Inventors: Akio Suzuki, Toru Fujita, Akinori Asai, Yusei Nagata, Shinichi Ohba, Takayuki Ohshiro, Matthew Partlow, Ron Collins, Stephen F.

Patent number: 10593165Abstract: To provide an auxiliary unit capable of reducing the number of signal lines for outputting warning information. A multi-output unit is connected to a plurality of sensor units via individual output lines 262a to 262h through which the plurality of sensor units output a detection result of each of the plurality of sensor units and a data line 261a for communicating with the plurality of sensor units. The communication control unit 104 communicates with each of the plurality of sensor units via the data line 261a and receives warning information transmitted by at least one of the plurality of sensor units. When receiving the warning information from at least one of the plurality of sensor units via the data line 261a, the common signal line 154 outputs a common output signal indicating the warning information to an external device.Type: GrantFiled: August 10, 2018Date of Patent: March 17, 2020Assignee: Keyence CorporationInventors: Kentaro Yamazaki, Akinori Nagata

Patent number: 9182259Abstract: An ultrasonic flow meter is equipped with a housing through which a liquid flows, and a pair of detection units disposed on opposite ends of the housing and including acoustic wave transmitting and receiving units capable of transmitting and receiving acoustic wave signals. Vibration generating mechanisms having vibration generating bodies arranged perpendicularly to the detection units are disposed on an outer circumferential side of the housing. In addition, when the flow rate of the liquid that flows through the housing is measured, the vibration generating bodies are energized and made to vibrate, such that gas bubbles, which adhere to cover members in contact with the liquid and that cover the acoustic wave transmitting and receiving units, are removed by the vibrations.Type: GrantFiled: April 30, 2014Date of Patent: November 10, 2015Assignee: SMC CORPORATIONInventors: Takamitsu Suzuki, Akinori Nagata
