Publication number: 20240248492Abstract: A system is provided which can achieve reliability of a notification about a moving manner of a work machine for a worker regardless of the distance between the work machine and the worker. A sign image M is projected onto a peripheral region of the worker (for example, a ground surface which is present in the vicinity of the worker to the extent that the worker is capable of visually recognizing the sign image M) by an unmanned aircraft 60. The sign image M is an image which represents a moving manner of a work machine 40. Thus, regardless of the distance between the work machine 40 and the worker, reliability of a notification about the moving manner of the work machine 40 for the worker is achieved compared to a case where the sign image M is projected onto an irrelevant place to the position of the worker.Type: ApplicationFiled: December 13, 2021Publication date: July 25, 2024Inventors: Yuki MORITA, Yusuke FUJIWARA, Kazuhiro UEDA, Yoichiro YAMAZAKI

Publication number: 20240231323Abstract: A maintenance device is applied to a bulk feeder including a feeder main body section, a track member, a vibration device, and a cavity group, and includes an initialization section and a vibration force control section. When the use time of the bulk feeder elapses a predetermined time, the initialization section returns a supply component existing in the cavity group toward a receiving region, and sets the cavity group to an initialization state in which the supply component does not exist in the cavity group. The vibration force control section increases the vibration force to be applied by the vibration device to the track member in the initialization section as compared with a case where the supply component is returned from the supply region toward the receiving region in order to adjust the number of the supply components conveyed to the cavity group when a board product is produced.Type: ApplicationFiled: March 9, 2021Publication date: July 11, 2024Applicant: FUJI CORPORATIONInventors: Yusuke YAMAZAKI, Yuji KAWASAKI
