Patent number: 10814837Abstract: An object of the present invention is to suppress variations in shape of flow channels to have an enlarged flow channel. When an attachment main body 51 of a lid member 50 is attached to a recessed attachment part 46 of a main body member 40, a pair of flange parts 52 provided to the lid member 50 abuts on the main body member 40. Therefore, the insertion amount of the attachment main body 51 into the recessed attachment part 46 in each product can be maintained approximately constant while enlarging a main channel MC and a pair of sub channels SS1 and SS2, which are formed by the main body member 40 and the lid member 50, and variations in shape of these flow channels can be reliably suppress.Type: GrantFiled: July 17, 2014Date of Patent: October 27, 2020Assignee: Mitsuba CorporationInventors: Takao Umezawa, Atsushi Otani, Hiroshi Yokoyama

Patent number: 10105754Abstract: A flow rate control valve configuring a meter-out circuit of an injection cylinder is an overlap type where a first port starts to be opened by a spool passing through an overlapping range. The control device holds a characteristic table linking a command value of a control command to the flow rate control valve and a velocity of a plunger including also the movement of the plunger which occurs due to a gap flow even if the spool is located in the overlapping range. Further, the control device specifies the command value corresponding to the target velocity set by operation of the input device based on the characteristic table, performs open control based on this command value, then performs the feedback control for realizing the target velocity.Type: GrantFiled: February 2, 2017Date of Patent: October 23, 2018Assignee: TOSHIBA KIKAI KABUSHIKI KAISHAInventors: Hiroshi Yokoyama, Shunsuke Takekawa
