Patent number: 11520108Abstract: An optic fiber adaptor includes two flexible engaging members and two positioning walls cooperating with one another to define an insertion slot. Each engaging member has a first inclined surface and a second inclined surface disposed behind the first inclined surface. A distance between the first inclined surfaces of the engaging members decreases rearwardly so as to facilitate pushing of a casing body of a ferrule assembly into the insertion slot. A distance between the second inclined surfaces of the engaging members decreases forwardly so as to facilitate pulling of the casing body out of the insertion slot. An optic fiber connecting device having the optic fiber adaptor is also disclosed.Type: GrantFiled: September 10, 2020Date of Patent: December 6, 2022Assignees: GLORIOLE ELECTROPTIC TECHNOLOGY CORP., HAKUSAN INC.Inventors: Li-Yun Chen, Masaaki Iwamoto

Patent number: 6787712Abstract: To provide a combination weighing apparatus capable of handling articles of various shapes automatically at a high speed, the combination weighing apparatus includes a supply unit (2) having a plurality of supply buckets (20i) each capable of discharging the article onto hoppers (40i) positioned therebelow. The supply buckets (20i) are drivingly supported by a transport unit including an endless support member (10) so as to circulate along a predetermined transport path. A discharge control is provided so that when some of the supply buckets (20i) are brought to a position corresponding to empty weighing hoppers (40i), the articles M within such supply buckets (20i) can be discharged therefrom onto the weighing hoppers (40i).Type: GrantFiled: July 17, 2001Date of Patent: September 7, 2004Assignee: Ishida Co., Ltd.Inventors: Yoshiharu Asai, Minoru Kubokawa, Masaaki Iwamoto

Patent number: 5621194Abstract: A combinational weighing machine has weigh hoppers for weighing articles, a dispersion feeder for dispersing articles to be weighed, supply troughs for supplying articles from the dispersion feeder to the weigh hoppers and a control unit for controlling overall operations of the machine inclusive of combining weight values outputted from the weigh hoppers and discharging articles from selected ones of these weigh hoppers. The weighing machine is placed inside a washing device which forms a closed chamber inside and covers the weighing machine from all its four sides as well as from above. Nozzles for emitting warm water and a cleaning liquid are provided inside this chamber such that the liquids are prevented from splashing the work areas around the machine. The washing device may be lifted and kept away from the weighing machine during a normal mode of operation of the latter.Type: GrantFiled: March 4, 1994Date of Patent: April 15, 1997Assignee: Ishida Co., Ltd.Inventors: Nobuo Koyama, Masaaki Iwamoto
