Patent number: 10775357Abstract: An inner protective cover 130 of a gas sensor forms an element-chamber inlet 127 having a first outside opening 128a, a second outside opening 128b, and an element-side opening 129. The second outside opening 128b is disposed such that the path of a measurement-object gas from the first outside opening 128a to the element-side opening 129 of the element-chamber inlet 127 communicates in the middle thereof with a first gas chamber 122, and that there is a path shorter than the shortest path of the measurement-object gas extending from an outer inlet 144a through the first outside opening 128a to a gas inlet 111.Type: GrantFiled: June 15, 2017Date of Patent: September 15, 2020Assignee: NGK INSULATORS, LTD.Inventors: Yosuke Adachi, Tetsuya Ishikawa, Jumpei Tanaka

Patent number: 10421293Abstract: A tablet printing apparatus and a tablet manufacturing method are provided which are capable of distinguishing and collecting a preceding tablet and a following tablet from each other when two or more tablets in contact with each other are carried. A tablet printing apparatus includes a carrying device 20 carrying tablets Tb, a sensor 30 detecting the tablet Tb being carried by the carrying device 20, a printing unit 50 performing, when the status changes from the status in which the sensor 30 the tablet Tb is not detected to the status in which the tablet Tb is detected, printing on the tablet Tb that has changed the status, and a collecting unit R distinguishing and collecting, when the time length at which the sensor 30 is detecting the tablet Tb is longer than the predetermined setting value because two or more tablets Tb in contact with each other are carried, the preceding tablet Tb and the following tablet Tb following thereto among two or more tablets Tb.Type: GrantFiled: July 20, 2018Date of Patent: September 24, 2019Assignee: SHIBAURA MECHATRONICS CORPORATIONInventors: Noritsugu Tanio, Jumpei Tanaka, Norihito Mafune, Junsuke Komito
