Abstract: A method to make probes of a probe card includes providing a blocking plate on an electroplating tank. The blocking plate has a plurality of openings according to the layout of contact pads on a probe head. There are bumps on the contact pads of the probe head. Continuous electroplating process can be executed after bumps (contact pads) contact electroplating solution in the electroplating tank through the openings of the blocking plate. By continuously moving the probe head according to the desired shape of probes, probes were formed by electroplating. These probes can be made into different shapes with good uniformity in elasticity and heights to increase the quality of electrical contact during wafer probing. Moreover, the process lead time and fabrication cost are saved.

Abstract: A method for manufacturing a spark plug which reduces the generation of spatters and the possibility of insufficient weld strength resulting from penetration depth insufficiency of a weld metal portion is disclosed. In accordance with the method, a chip joint face formation portion of a center electrode is formed from a heat-resistant alloy predominantly containing Fe or Ni. A noble metal chip is attached to a chip joint face of the chip joint face formation portion to thereby form a chip-attached assembly. A full-circled laser-beam weld metal portion is formed on the chip-attached assembly in such a manner as to intrude into the noble metal chip and into the chip joint face formation portion. A graded-index-type fiber optic cable is used as an optical transmission path extending between a laser beam generator and an optical emission section. A laser beam which is transmitted from the laser beam generator through the cable irradiates the chip-attached assembly while being condensed.

Abstract: An apparatus and method for generating a low concentration of gas within a carrier gas flow employing one or more miniature one-piece cylinders filled under pressure with a pure gas, or a concentrated gas balanced with an inert gas or gas mixture. Released from the cylinder through a pierced or other controlled opening, the flow of the gas is regulated by a pressure regulator and a micro orifice to be blended into a steady stream of diluent gas, typically ambient air, to form a desired gas concentration. No gas is generated if the pressure of the gas in the cylinder, which is monitored constantly by a pressure transducer, is below a predetermined level. The apparatus can be built into a portable device, or an automated docking station (or calibration station) for testing and calibrating gas detection and monitoring instruments, or into a fixed gas detection system for performing such functions.

Abstract: A circular saw includes a table having an upper surface for placing a workpiece thereon. A saw unit has a saw blade mounted thereon and is supported on the table such that the saw unit is movable in a horizontal direction parallel to the upper surface of the table and is movable in a vertical direction perpendicular to the upper surface of the table. At least one of a first lock device and a second lock device is provided. The first lock device is operable to prevent the saw unit from moving in the horizontal direction in response to the movement of the saw unit in the vertical direction. The second lock device is operable to prevent the saw unit from moving in the vertical direction in response to the movement of the saw unit in the horizontal direction.

Abstract: This invention solves the problem of reducing the fluid friction resistance accompanying relative movement of surfaces of a solid and a liquid. A superhydrophobic coating acting as a substrate for a gaseous lubricant of very low viscosity, reducing the fluid skin friction, has a hierarchic fracal structural of the surface wherein the forms of the first hierarchic level (2, 3, 9) are located at the coating's substrate, and the forms of each successive hierarchic level (22, 33, 99) are located on the surface of the previous hierarchic level and the forms of individual higher hierarchic levels reiterate the forms of the lower hierarchic levels. Forms of at least two hierarchic levels of rows (2, 22) and ridges (3, 33, 99) occur in the coating and, also, the surface has anisotropic geometry, maximally developed fractally in the direction transverse to the direction of flow and maximally smooth in the direction of flow and, also, has channels located in the coating's substrate to ensure gas flow.

Abstract: Method for determining pressure profiles in wellbores, flowlines and pipelines flowing singlephase and multiphase fluids and use of such a method. The flow is temporarily stopped or restricted with a quick acting valve and the pressure is continuously recorded at a point a short distance upstream, using the Joukowsky equation: ?p_a=? u a, where ?(kg/m3) represents the fluid density, u(m/s) the fluid flowing velocity and a (m/s) the speed of sound in the fluid, to estimate the magnitude of the water hammer and using the Darcy-Weisbach equation: ?_f=(f/2)(?L/d)?u^2, where f (dimensionless) is the friction factor, L (m) the pipe length, d (m) pipe diameter, (kg/m3), ? (kg/m3) fluid density and u (m/s) fluid velocity, to determine the frictional pressure drop, thereby obtaining a time-log of the pressure change in the wellbore, flowline or pipeline measured.

Abstract: A crenellated resistor made from a carbonaceous material and having the shape of a hollow cylinder for use in furnaces working at high temperature. The resistor is characterized by the thickness of the cylinder walls which follows a profile determined so as to produce an even temperature on the surface of the resistor when it is working. Thus, the wall has a radial thickness which decreases in a transition section from the peripheral edge to the internal edge. The resistor configuration allows elimination of hot spots which may appear when electricity flows through the resistor.
