PROBLEM TO BE SOLVED: To provide a system for improving the long-term reliability of an integrated circuit package containing a pattern-formed metal thermal interface (PMTI), and its method. SOLUTION: The system and a method improve the long-term reliability of the integrated circuit package which contains a pattern-formed metal thermal interface (PMTI). The method includes processes to join a heat sink to a thermal source, to prepare a PMTI material between the thermal source and heat sink, and to arrange a partial sealing portion of a compressed malleable metal to prevent the PMTI from being moved out from its position at a subjected load.

PROBLEM TO BE SOLVED: To allow access to a cooling system for maintenance, repair, upgrade, or the like. SOLUTION: In one embodiment, a device for dispersing the heat from a heat generating device comprises a base that has a first side surface so constituted as to thermally couple with the heat generating device, a cooling channel of air-base which is coupled with the base for dispersing at least a part of the heat through air, and a cooling channel of fluid-base which is coupled with the base for dispersing at least a part of the heat through a fluid. The cooling channel of air-base and the cooling channel of fluid-base operate simultaneously or independently, to disperse heat from the heat generating device. COPYRIGHT: (C)2008,JPO&INPIT

Abstract:
PROBLEM TO BE SOLVED: To provide a tracing system which eliminates the need for a headgear and is precise by using a diode laser so as to measure period and amplitude generated by interference between the luster of the cornea and red-eye reflection from the retina. SOLUTION: A unidirectional scan is made by a rotary polygon mirror 75 with the laser light beam emitted by the diode laser 71. The light beam reflected by the rotary polygon mirror 75 passes through a light beam forming optical element 76 to reach the eye 77 of a user. The light beam reflected by the user's eye 77 returns through the light beam forming optical element 76 and is reflected again by the rotary polygon mirror 75 to reach an optical detector 79 through a baffle 78. The output of the optical detector 79 is an AC signal and corresponds to the saw-tooth wave modulation of the original laser light beam. This detected AC signal is inputted to a signal processing circuit 80 to determine evaluation regarding where the user is seeing according to a statistical model.

In one aspect, a cooling system is provided including a cooling tower; one or more modular refrigeration chiller units; and a water loop that can be selectively directed through the cooling tower, through one or more of the modular refrigeration chiller units or through a combination thereof. Another cooling system is provided including a solar cooling unit; one or more modular refrigeration chiller units; and a water loop that can be selectively directed through the solar cooling unit, through one or more of the modular refrigeration chiller units or through a combination thereof.
Abstract:
Measurement apparatus and procedure for use with lithographic equipment is provided for the construction of electronic and other devices wherein a photoresist is deposited as a layer upon a substrate (20). A Nomarski differential interference contrast microscope (62) in conjunction with a scanned image detector is employed to examine verification marks (28, 30) produced by projection of an overlay, such as the mask or reticle (94), upon the photoresist layer. The projection results in a production of verification marks (28, 30) in the form of a latent image which, while invisible with conventional viewing means, can be viewed by phase-contrast imaging employing differential phase shift. Various characteristics of the resultant image are employed to align secondary verification marks (30) with primary verification marks (28) previously provided on the substrate (20), and to allow for a checking of line width, dosage, focusing, temperature control, and global alignment. Observation of the photoresist is accomplished with radiation at lower frequency than the exposure radiation, the latter being significantly absorbed, by the photoresist, the photoresist being transparent to the observation radiation to permit reflection from top and bottom surfaces of the photoresist.
Abstract:
A solar concentrator includes an optical member having a focal point. The optical member is configured and disposed to direct incident solar radiation to the focal point. A support member is positioned adjacent to the focal point of the optical member. A solar energy collector is supported upon the support member. The solar energy collector is positioned at the focal point of the optical member. A base member is positioned in a spaced relationship from the support member. The base member and the support member define a chamber section that is in a heat exchange relationship with the solar energy collector. The chamber section is configured to absorb and dissipate heat from the solar energy collectors.
