摘要： Drilling fluid additives are prepared by complexing humic acids and/or lignins, with three compounds of zirconium, nickel and iron. The metal composition of the additives is 1.3 to 2.5% of zirconium, 0.8 to 1.5% of nickel and 0.8 to 1.5% of iron, and is totally 3.0 to 5.5%. Thus, the drilling fluid additives, containing no chromium, can be used in wide temperature range for the drilling of oil, geothermal or gas wells with less gelation even by various contamination and cause no serious environmental pollution.

摘要： A dividing method for a workpiece having a substrate with a film formed on the front side thereof. A first laser beam is applied to the film from the front side of the workpiece along the streets formed on the film, thereby forming a plurality of laser processed grooves along the streets to cut the film along the streets. Thereafter, an adhesive tape is attached to the front side of the workpiece. Thereafter, a second laser beam is applied to the substrate from the back side of the workpiece along the streets in the condition where the focal point of the second laser beam is set inside the substrate, thereby forming a plurality of modified layers inside the substrate along the streets. Thereafter, the adhesive tape is expanded to thereby divide the substrate along the streets, thereby obtaining a plurality of individual devices. Thereafter, the back side of the substrate of each device is ground to remove the modified layers and reduce the thickness of each device to a predetermined thickness.

摘要： A wireless communication system includes wireless terminals. Each of the wireless terminals includes an SDM transmitting unit that includes antennas and generates directional radio signals to be transmitted to other terminals, each of which is obtained by superimposing radio signals at the antennas, each of which is composed of modulated data for each of the other terminals; a single-system receiving unit; and a TDMA control unit that controls a transmission of the SDM transmitting unit and a reception of the receiving unit in a time division manner. Using a TDMA scheme, the wireless terminals are controlled such that one of the wireless terminals acquires a transmission right for a predetermined time period to simultaneously transmit the generated directional radio signals from the SDM transmitting unit, while during the predetermined time period, the receiving units of the other wireless terminals having no transmission right simultaneously receive their corresponding directional radio signals.

摘要： A dividing method for a platelike workpiece having a two-layer structure such that a solder layer (metal layer) is formed on the back side of a wafer (substrate). First, a modified layer is formed in the wafer along each division line formed on the front side of the wafer. Thereafter, the workpiece is bent along each division line to thereby divide the wafer along each division line from the corresponding modified layer as a starting point and simultaneously form a weak portion in the solder layer along each division line. Thereafter, an expandion tape attached to the solder layer is expanded to apply an external force to the solder layer, thereby dividing the solder layer along each division line from the corresponding weak portion as a starting point. Thus, the workpiece is completely divided.
