Publication number: 20190011303Abstract: Provided is a flow meter capable of logging data more reliably. In this operation, a detection element repeatedly detects a physical quantity related to a flow rate of a fluid flowing in a pipe in a predetermined sampling cycle. Based on physical quantities, a calculation part sequentially calculates the flow rate of the fluid in the pipe. Further, a time measurement part calculates the time. A control storage part is caused to store a logging target, a logging cycle, and logging start definition information. Based on the logging start definition information, a control part automatically starts logging of the logging target in response to startup of the flow meter, and causes a log storage part to store the time measured by the time measurement part and a numerical value of the logging target in association with each other in every logging cycle.Type: ApplicationFiled: June 7, 2018Publication date: January 10, 2019Applicant: Keyence CorporationInventors: Yohei HASHIMOTO, Satoru TOMOSHI, Hiroki MATSUI

Patent number: 9951709Abstract: A hybrid electric vehicle comprises an internal combustion engine and an electric motor/generator connected via a first clutch. In response to a system stop request in a vehicle stop state, a rotation speed of the internal combustion engine is decreased to a predetermined rotation speed higher than a predetermined resonance frequency band by a negative torque applied to the internal combustion engine from the electric motor/generator via the first clutch. Then, the disengagement of the first clutch starts. The rotation speed of the engine falls below the predetermined resonance frequency band within a predetermined period from the start of the disengagement. As a consequence, the required period from a stopping operation of the internal combustion engine until actual operation stop thereof in a vehicle stationary state is reduced.Type: GrantFiled: March 15, 2013Date of Patent: April 24, 2018Assignee: NISSAN MOTOR CO., LTD.Inventors: Hiromichi Murata, Hiroki Matsui, Jun Amemiya
