Patent number: 11009340Abstract: A film thickness measuring apparatus includes a displacement sensor, and a film thickness calculator that includes a first processor, a second processor, and a third processor. The displacement sensor detects displacement of a sheet in its thickness direction at a location opposite to a portion of a terahertz scanner from which a terahertz wave is applied to a conveyance path. In accordance with a detection signal provided by the displacement sensor, the first processor determines the speed of displacement of the sheet in its thickness direction while the sheet is conveyed along the conveyance path. In accordance with the speed of displacement, the second processor corrects a scan waveform acquired by the terahertz scanner. In accordance with the peaks of the intensity of the terahertz wave that appear in the scan waveform corrected by the second processor, the third processor calculates the thickness of a film formed on the sheet.Type: GrantFiled: March 19, 2018Date of Patent: May 18, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masanori Miura, Jun Takayanagi

Patent number: 10494973Abstract: A catalytic converter includes: a tubular casing including at least a pair of holding tubular parts and a reduced diameter tubular part that integrally connects the holding tubular parts to each other; and a monolithic catalyst carrier accommodated in each of the holding tubular parts, the reduced diameter tubular part being obtained by press-forming a portion, between the holding tubular parts, of a casing material of a tubular shape that corresponds to that of the holding tubular parts. Flat parts are formed respectively in a plurality of places at intervals in a peripheral direction of the reduced diameter tubular part, a sensor being attached to at least one of the flat parts. Accordingly, a press load when press-forming the reduced diameter tubular part is suppressed from becoming large and unequal in the peripheral direction of the reduced diameter tubular part.Type: GrantFiled: June 29, 2018Date of Patent: December 3, 2019Assignees: Yutaka Giken Co., Ltd., Honda Motor Co., Ltd.Inventors: Jun Takayanagi, Toshihiro Ooka, Noritaka Yamamoto, Kazumasa Ishii, Yoshiaki Hatakeyama
