Abstract: The present invention provides a heat dissipation member for use in the optical disk drive. The present invention includes an outer frame and a chassis. The chassis has a drive module, a pickup module and two guide rods. A heat dissipation member is disposed on the pickup module and is in contact with a laser diode of the pickup module.

Abstract: A method is described for increasing the activity of restriction endonuclease mutants that have altered binding or cleavage activities. Restriction endonuclease variants can carry one or more amino acid substitutions that change substrate specificity and at the same time decrease the enzyme catalytic activity. A method is described for isolating derivatives of the endonuclease variants by subjecting them to additional rounds of mutagenesis and screening in a dinD::lacZ indicator strain, such that second-site mutations within the nucleotide coding sequence of the endonuclease are obtained that increased the enzyme specific activity.

Each connector has at least one wafer which houses a plurality of terminals preferably crimped and electrically terminated to the ends of the wires. The wire harness machine preferably utilizes a pallet which holds all of the wafers of one wire harness. A conveyor transports the pallet and wafers through a series of stations which perform automated manufacturing steps. The first station is a terminal inserter which inserts and locks the terminals within pre-assigned cavities of the wafers.

Abstract: An electrical connector assembly comprises a connector and a dielectric housing. The connector includes a case from which a first wing and a second wing. Each wing defines a through hole and an extending plane which is inclined relative to a bottom surface of the case. The housing on which the connector is mounted has an inclined base defining an opening and a first sleeve and a second sleeve. A top surface of each sleeve defines a mating surface, the two surfaces being parallel to one another and inclined relative to the base. After the plug of the connector is inserted through the opening of the housing, the mating surfaces mate with the extending planes of the corresponding wing and both the through holes and corresponding threaded recesses of the sleeves which are aligned in a vertical direction thereby facilitating an insertion of bolts to secure the connector to the housing.

Abstract: This invention provides a female terminal of one-piece construction for a printed circuit board in which the rectangular receptacle has an interlock arrangement that reduces the length of the open seam at the fourth corner of the rectangular receptacle. The interlock arrangement is accomplished by fabricating one side wall of interlocking segments that are integrally attached to opposite end walls of the rectangular receptacle so that the open seam does not run the entire length of the receptacle. The interlocking side wall segments are preferably shaped to minimize the size of the sheet metal blank to save material and reduce manufacturing costs. The contact tongues of the female terminal are also preferably shaped to provide one or more of the following features—an open and controlled contact gap to lower terminal engage force while maintaining a stable contact force; over stress projection; and double sided mating capability.

Abstract: A genomic DNA library of Thermus filiformis was constructed using pBR322 as a cloning vector. The methylase selection method was used to clone the TfiI methylase gene (tfiIM). A clone carrying an active TfiI methylase was identified. After sequencing the complete TfiI methylase gene and its downstream DNA sequence, a recombinase homolog was found. Because the methylase and its cognate endonuclease gene are located in proximity to each other in a particular restriction-modification system, efforts were made to clone the upstream DNA by inverse PCR. After two rounds of inverse PCR, one open reading frame (ORF1) was found upstream of the TfiI methylase gene. This ORF1, containing a Shine-Dalgarno sequence and a TATA box on the upstream side, was cloned and expressed, and TfiI endonuclease activity was detected in crude cell extracts. It is concluded that ORF1 encodes TfiI restriction endonuclease.

Abstract: The present invention is a chemical vapor deposition of tungsten(W-CVD)process for growing low stress and void free interconnect. The method of this invention utilizes two steps W-CVD process by two chambers. The first step, filling tungsten metal completely in the contact hole, is performed in the first chamber. The second step, forming a tungsten layer for interconnect, is performed in the second chamber. Because of using two different chambers, the method of this invention can adjust the temperature of the process and the gas flow of the WF.sub.6 vapor of the process for different required the two steps. The second step of chemical vapor deposition of tungsten by adjusting the temperature and the gas flow has reduced greatly the stress of the second conductive layer. Moreover, the first step of chemical vapor deposition of tungsten by adjusting the temperature and the gas flow prevents voids in the contact hole or in the via hole.
