Publication number: 20240116364Abstract: A virtual image display apparatus includes a housing having a first housing part and a second housing part. The first housing part is located on a side facing in a first direction. The second housing part is located on a side facing in a second direction being opposite to the first direction. A composite wall is located at the housing on a side facing in a third direction being perpendicular to the first direction. The composite wall includes a first front wall portion and a second front wall portion. The first front wall portion is extended from the first housing part. The second front wall portion is extended from the second housing part. The first and second front wall portions have an interference avoidance structure that avoids interference when the first and second front wall portions approach each other by receiving a load.Type: ApplicationFiled: December 20, 2023Publication date: April 11, 2024Inventors: Yasunori NINOMIYA, Syunichi Okada, Yusuke Ohta, Kenta Futamura

Patent number: 11933521Abstract: A hot water supply device includes a combustion part, a combustion fan, a heat exchange part, a water supply part, a hot water discharge part, and a control part. In the hot water supply device, in a pre-purge step of a heating operation, the presence or absence of a disturbance factor is determined based on rotational responsiveness and deviation of the combustion fan with respect to a scavenging rotation speed. When there is no disturbance factor, in an ignition step, detection of a failure sign is performed based on responsiveness and deviation of the combustion fan with respect to an ignition rotation speed.Type: GrantFiled: December 9, 2021Date of Patent: March 19, 2024Assignee: NORITZ CORPORATIONInventors: Toshihiko Hamagami, Hideyuki Okada, Kenta Yamanishi, Hisataka Hayase, Kazuhiro Nishimura

Patent number: 11445786Abstract: A fastening tape having flexibility in a longitudinal direction of the fastening tape. The fastening tape includes a plurality of fasteners, a support, and magnetic material positioned on the support. The support defines a plurality of plateaus and a plurality of valleys. The magnetic material is positioned on at least a portion of one of the plurality of plateaus or the plurality of valleys of the support such that a height of the magnetic material varies in the longitudinal direction. Because the height of the magnetic material varies, the fastening tape is more flexible in the longitudinal direction. In some cases, the fastening tape is also flexible in the lateral direction.Type: GrantFiled: December 18, 2019Date of Patent: September 20, 2022Assignee: YKK CorporationInventors: Zhiyu Ren, Tsuyoshi Minato, Atsushi Nakaya, Kenta Okada

Patent number: 11051590Abstract: The molded surface fastener has a base portion, right and left resin-intrusion-preventing wall portions standing on the base portion, and a plurality of engaging elements disposed between the right and left resin-intrusion-preventing wall portions. The resin-intrusion-preventing wall portions contain magnetic particles, and at least a part of a region formed of the resin-intrusion-preventing wall portions and the base portion has a concentration gradient portion in which a concentration of the contained magnetic particles is decreased toward at least one direction. This makes it possible to enhance the adhesion property between the part containing the magnetic particles and the part substantially containing no magnetic particles, and to suppress occurrence of cracks or the like between the containing part and the non-containing part of the magnetic particles at the time of manufacturing the molded surface fastener and at other times.Type: GrantFiled: February 19, 2016Date of Patent: July 6, 2021Assignee: YKK CorporationInventors: Hiromasa Abe, Ayumi Fujisaki, Kenta Okada
