Abstract:
A method of providing a decorative metal pattern on an electrically non-conductive substrate, such as a glass or plastic substrate, which includes applying a mixture of a heat fusible material, such as glass or plastic, with a metal having a particle size less than about 500 mesh constituting at least 50% of the mixture, to the substrate in the desired pattern, heating the so-applied mixture until the heat fusible material fuses and bonds to the substrate, cleaning the substrate with the pattern thereon, and electroplating the pattern with the desired finish metal. In one method in which the mixture includes glass, a negative resist is adhesively secured to the substrate and the mixture is applied. The resist disintegrates upon heating. In another method, used when the substrate is plastic, a mixture of plastic and metal in paste form is applied to the substrate by silk screening or pad printing to form the pattern. In both cases, the pattern is bonded to the substrate by intermolecular bonding and has sufficient conductivity for electroplating without intermediate processing. Also, articles produced by such methods.
Abstract:
A packaging and cooling structure for integrated circuit chips in electronic equipment is provided in which the chips are resiliently mounted on wafers which are centrally located in chambers within a housing. A liquid coolant is forced through orifices to spray the coolant on the wafers behind the chips and on the chips themselves providing both high velocity convective cooling and phase change boiling heat transfer. A temperature sensor and control are provided to sense and control the temperature within the electronic equipment.
Abstract:
A surgical instrument for obtaining biopsies, performing microsurgery and bipolar microelectrocautery. The instrument head includes opposing jaw members which open and close during the operating procedures. The angle of the instrument head relative to the instrument frame is adjustable to effectively operate on varying surfaces. The angle can be continuously adjusted while the instrument is in an operating position.
Abstract:
The sensitivity of the threshold voltage in MOSFET devices to changes in substrate voltage may be reduced at a given temperature by the introduction of sufficiently deep energy level, low diffusivity impurities into the depletion region under the gate of the MOSFET.
Abstract:
A surgical instrument for performing gynecological procedures comprising a first forceps lever having a forwardly disposed section insertable into a vaginal cavity, an intermediate section and a rearwardly disposed handle section, a second forceps lever having a forwardly disposed section insertable into a vaginal cavity with the insertable section of the first forceps lever, an intermediate section pivotally connected to the intermediate section of the first forceps lever and a rearwardly disposed handle section cooperable with a handle section of the first forceps lever, the insertable section of the first forceps lever having a longitudinally disposed bore, a plunger member disposed in the longitudinally disposed bore and displaceable longitudinally therein, such plunger member being insertable in the uterine canal when the insertable sections of the forceps levers are inserted into a vaginal cavity, flexible material disposed on the plunger member and expandable to engage the wall of the uterine cavity and provide an expansive bearing contact therewith, and the insertable section of the second forceps lever having a lip portion engageable with the cervix of the uterus when the insertable sections of the forceps levers are inserted into a vaginal cavity, the plunger member is inserted in the uterine canal and the handle sections are moved together, thereby causing the uterine cervix to be clamped between the forceps levers.
