Publication number: 20060254753Abstract: A flexible loop thermosyphon is provided having a flexible, hermetic, outer tube and a flexible, non-hermetic, inner tube, positioned concentrically within the outer tube, forming an annulus between the outer tube and inner tube. The annulus acts as a vapor conduit transferring vapor to the loop thermosyphon condenser while the inner tube acts as a condensate conduit returning liquid to the loop thermosyphon evaporator.Type: ApplicationFiled: August 2, 2006Publication date: November 16, 2006Inventors: Alfred Phillips, Dmitry Khrustalev, Kevin Wert, Michael Wilson, Jonathan Wattelet, John Broadbent

Patent number: 6828675Abstract: A modular cooling system (10) is provided for use in an electronics enclosure (12) mounting a plurality of heat generating electronic components (14). The cooling system (10) includes a cooling liquid supply manifold (16), a cooling liquid return manifold (18), and a plurality of cooling modules (20) that are selectively mountable into the electronic enclosure (12). The cooling system (10) also includes a wall (64) fixed in the enclosure to separate the electronic components (14) from the manifolds (16,18) to shield the electronic components (14) from any of the cooling liquid (52) should it leak from the system (10).Type: GrantFiled: September 26, 2001Date of Patent: December 7, 2004Assignee: Modine Manufacturing CompanyInventors: Stephen B. Memory, Fredrick E. Ganaway, C. James Rogers, Anthony C. DeVuono, Alfred Phillips, Zhijun Zuo

Patent number: 5404372Abstract: A laser array for a large number of lasers which are manufactured on a single metal level is taught. Briefly stated the cavity length of the lasers are shortened so as to provide for metal lands or traces to be disposed adjacent to rear facets of the laser for eventual interconnection with pads. The diminution in cavity length does not degrade laser performance or characteristics, while performance and characteristics amongst adjacent lasers is similar.Type: GrantFiled: October 31, 1991Date of Patent: April 4, 1995Assignee: International Business Machines CorporationInventor: Alfred Phillips, Jr.

Patent number: 5301202Abstract: A semiconductor ridge waveguide laser having a high value of horizontal far-field wherein the laser structure includes a substrate, a first or lower cladding layer composed of a AlGaAs on the substrate, an acting layer on the lower cladding layer, and a second or upper cladding layer composed of AlGaAs on the active layer. The upper cladding layer includes a raised ridge portion formed by etching the upper cladding layer through a mask. A contact layer is disposed on top of the ridge portion. The aluminum mole concentration of the lower cladding layer is greater than the aluminum mole concentration of the upper cladding layer. This forces the optical mode towards the upper cladding layer and results in an increased lateral waveguide confinement that produces a high horizontal far-field.Type: GrantFiled: February 25, 1993Date of Patent: April 5, 1994Assignee: International Business Machines, CorporationInventors: Christoph S. Harder, Sridhar V. Iyer, Heinz P. Meier, Alfred Phillips, Jr., Abbas Behfar-Rad

Patent number: 5130528Abstract: A heterojunction optical switch is taught. Briefly stated, birefringence in the form of a Pockel Cell is utilized such that biasing of the Pockel Cell permits the passage of light therethrough. Preferably, a light detector and resistor are electrically in parallel with the Pockel Cell such that light impinging upon the light detector causes the Pockel Cell to be reverse biased with the result that a separate light source may pass through the Pockel Cell. In this fashion, the Pockel Cell operates as a true optical switch.Type: GrantFiled: March 1, 1991Date of Patent: July 14, 1992Assignee: International Business Machines CorporationInventor: Alfred Phillips, Jr.

Patent number: 4154626Abstract: An improved field effect transistor device in a monocrystalline semiconductor body provided with source and drain regions and a gate electrode disposed over the channel between the source and drain regions wherein at least the drain region is formed of a first region where the impurity concentration increases with depth with the peak concentration being spaced inwardly from the major surface, and a second region located within the first region having a peak impurity concentration at the major surface. The drain region structure in operation promotes the current flow between the source and drain to flow deeper in the channel region and spaced from the gate dielectric layer.In the method for forming the field effect transistor, an impurity is introduced into the semiconductor body underlying at least the ultimate drain region, an epitaxial semiconductor layer deposited, and a second impurity region formed over the first region to form the drain contact.Type: GrantFiled: February 24, 1978Date of Patent: May 15, 1979Assignee: International Business Machines CorporationInventors: Richard C. Joy, Ingrid E. Magdo, Alfred Phillips, Jr.

Patent number: 4080087Abstract: A railless walkway for blind and visually handicapped persons is constructed using foot plates fastened to the ground. By feeling humps made into the foot plates, the blind are guided along walkways without the use of rails or canes. Variations in the shape and/or number of humps provide additional information as to walkway directions, such as turns, steps, stairs, rest areas, and the like. The foot plates are fabricated out of permanent, solid material and are either incorporated in the walkway during its construction or are fastened permanently to the walkway if added later.Type: GrantFiled: May 5, 1977Date of Patent: March 21, 1978Assignees: Curtis Alfred Phillips, Linda Louise PhillipsInventor: Curtis Alfred Phillips
