Patent number: 10578218Abstract: A vacuum valve comprises: a housing configured such that a flow path of gas passing through a pair of opposing openings is formed; a valve body; a sealing body; a sealing body drive section configured to drive the sealing body in upstream and downstream directions of the gas; and a mechanical stopper including a restriction section configured to inhibit, at a restriction position, movement of the sealing body in the gas downstream direction. The mechanical stopper is disposed movable to a selected one of a first position at which movement of the sealing body toward a gas downstream side is inhibited at the restriction position or a second position at which movement of the sealing body from the restriction position to a non-restriction position on the gas downstream side is allowed.Type: GrantFiled: January 6, 2018Date of Patent: March 3, 2020Assignee: SHIMADZU CORPORATIONInventor: Tatsuhiro Taguchi

Patent number: 10012316Abstract: A slide valve comprises: a casing having a pair of facing flow channels; a slide plate inserted into and removed from a space between the flow channels; and an annular sealing body slidingly moving in a facing direction of the flow channels inside the casing and coming into contact with the slide plate inserted between the flow channels to bring the slide valve into a closed state. A first sealing member sealing a gap between the sealing body and the inner peripheral wall surface is disposed on an inner peripheral surface of the annular sealing body and a second sealing member sealing a gap between the sealing body and the outer peripheral wall surface is formed on an outer peripheral surface of the annular sealing body.Type: GrantFiled: June 16, 2015Date of Patent: July 3, 2018Assignee: SHIMADZU CORPORATIONInventors: Tatsuhiro Taguchi, Masahito Kogame

Patent number: 6772917Abstract: A granular liquid crystal of uniform grain diameter is discharged from a liquid crystal application unit. A charged plate ionizes the discharged granular liquid crystal. A power source supplies a plus voltage to the charged plate via a switch which turns on or off a supplied voltage from the power source. If the switch is turned on, the granular liquid crystal is ionized, and the ionized granular liquid crystal is deflected by a deflecting plate to reach a substrate. On the other hand, if the switch is turned off, the granular liquid crystal is not ionized, and not deflected by the deflecting plate to be captured by a garter. The switch is turned on or off in synchronism with the frequency of the piezoelectric transducer, whereby a desired amount of liquid crystal can be dripped on the substrate.Type: GrantFiled: June 25, 2002Date of Patent: August 10, 2004Assignee: Shimadzu CorporationInventor: Tatsuhiro Taguchi
