Vapor Delivery System

View page
US Patent:
20030063901, Apr 3, 2003
Filed:
Jul 16, 2002
Appl. No.:
10/196572
Inventors:
Youfan Gu - Superior CO, US
Paul Dozoretz - Hudson CO, US
Benjamin Goss - Boulder CO, US
David Neumeister - Loveland CO, US
James Mueller - Lafayette CO, US
Donald Higgins - Hudson NH, US
International Classification:
F22B001/28
US Classification:
392/394000, 392/403000
Abstract:
The present invention provides a vapor delivery system and method for efficiently producing water vapor on demand. More particularly, the present invention produces low-temperature water vapor, without the formation of ice, by maintaining a sufficient volume of water at a sufficient temperature within a vaporizer chamber when the pressure in the vaporizer chamber is lowered.

Method And Apparatus For Preventing Ald Reactants From Damaging Vacuum Pumps

View page
US Patent:
20060264045, Nov 23, 2006
Filed:
May 23, 2005
Appl. No.:
11/136610
Inventors:
Youfan Gu - Superior CO, US
David Neumeister - Loveland CO, US
International Classification:
H01L 21/44
C23C 16/00
US Classification:
438680000, 118719000
Abstract:
A secondary reaction chamber with a mesh reactor element and a heater assembly are positioned in a foreline between a CVD reaction chamber and a vacuum pump to mix and react all previously unreacted precursor reactants to remove them from the effluent before they can reach and damage the vacuum pump.

Two-Stage, Slow-Start Valve Apparatus And Method

View page
US Patent:
20120153193, Jun 21, 2012
Filed:
Dec 15, 2010
Appl. No.:
12/968551
Inventors:
Youfan Gu - Superior CO, US
David Neumeister - Loveland CO, US
Kevin Grout - Denver CO, US
Assignee:
MKS INSTRUMENTS, INC. - Andover MA
International Classification:
F16K 31/12
US Classification:
251 28
Abstract:
A two-stage, slow-start valve includes a minor valve assembly inside a major valve closure member of a major valve closure assembly so that fluid can flow through the valve at a higher rate by opening the major valve assembly or at a lower rate by opening the minor valve assembly while the major valve closure assembly is closed in order to allow fluid to flow in an alternate flow path through the major valve closure member. The example minor valve closure assembly has a minor valve closure member that is actuated to open by a minor valve piston on which minor valve actuating fluid is applied to the minor piston via a diaphragm seal positioned between the minor piston and the minor valve actuating fluid. Both the major valve closure assembly and the minor valve closure assembly can be pneumatically actuated to open.

Actively Cooled Vacuum Isolation Valve

US Patent:
20190271410, Sep 5, 2019
Filed:
May 10, 2019
Appl. No.:
16/408752
Inventors:
- Andover MA, US
David F. Broyer - Kingston NH, US
David C. Neumeister - Longmont CO, US
Bradly Raymond Lefevre - Lakewood CO, US
Assignee:
MKS Instruments, Inc. - Andover MA
International Classification:
F16K 49/00
F16K 1/46
F16K 51/02
F16K 41/10
F16K 1/12
F16K 3/06
F16K 1/22
F16K 31/122
Abstract:
A cooled isolation valve includes a valve body, a stationary element coupled to the valve body, and a movable closure element movable with respect to the stationary element between a closed position in which the movable closure element and the stationary element are brought together and an open position. One of the movable closure element and the stationary element includes a sealing element. In the closed position of the movable closure element, the sealing element provides a seal between the movable closure element and the stationary element. A fluid channel is formed in contact with the movable closure element and movable with the movable closure element with respect to the stationary element, such that a fluid in the fluid channel effects heat transfer in the movable closure element. A bellows of the isolation valve can include a metallic substrate with a ceramic coating.

Method Of Two-Stage Flow Control

View page
US Patent:
20140130876, May 15, 2014
Filed:
Jan 23, 2014
Appl. No.:
14/162514
Inventors:
- ANDOVER MA, US
David Neumeister - Loveland CO, US
Kevin Grout - Denver CO, US
Assignee:
MKS INSTRUMENTS, INC. - ANDOVER MA
International Classification:
F16K 1/52
US Classification:
137 1, 137630
Abstract:
A valve has a major valve closure member with a valve stem for opening and closing a major port in a valve chamber. An alternate flow path extends through the major valve closing member. Flow is controlled through the alternate flow path by directing a minor valve actuating fluid through the valve stem to apply pressure on a minor valve piston in the major valve closure member to move a minor valve closure member in the major valve closure member between a closed mode in which the minor valve closure member closes the alternate flow path and an opened mode in which the minor valve closure member opens the alternate flow path. The minor valve actuating fluid is sealed from the alternate flow path by a flexible diaphragm positioned between the minor valve actuating fluid and the minor valve piston, so the pressure of the minor valve actuating fluid is applied to the minor valve piston via the flexible diaphragm.
