Abstract: To feed stably fuel through a fuel injection valve for a long period and to stabilize pressure controlling characteristics of a fuel pressure controlling valve, a fuel case is partitioned to form a fuel introduction chamber, a pump receiving chamber and a fuel discharge chamber. A fuel pump is received in the pump receiving chamber, an intake passage thereof communicates to the fuel introduction chamber and a discharge passage is opened to the inside of a filter in fuel discharge chamber. Fuel discharged from the fuel pump is fed into the inside of the filter from the discharge passage and clean fuel is fed into a cleaned fuel discharge chamber. The clean fuel within the cleaned fuel discharge chamber is fed from a fuel discharge passage to a fuel distribution pipe and fed from a fuel introduction passage of the fuel pressure controlling valve to the fuel chamber thereof.

Abstract: A method of extracting active mineral liquid from a rock such as granite is described. This method comprises charging an extraction vessel with finely divided granite at ambient temperature and pressure; introducing an aqueous ammonia solution with agitating and then diluted sulfuric acid into the vessel; introducing 98% ethyl alcohol at below 80° C. into the vessel to elevate the inner pressure of the vessel to 2-3 kg/cm2 for facilitating the formation of complexes; and agitating the resulting reaction mixture for 20-160 minutes at 80° C. to 85° C. while maintaining the internal pressure of the vessel. The active mineral liquid is advantageously used as a mineral source for soils, animals, plants, the human body and so forth, and as an agent for the purification of waterworks as well as for the treatment of wastewater.

Abstract: An improved method and apparatus for safely introducing sample into a flow stream of a supercritical fluid chromatography system is described. The sample injection method improves safety of injection by eliminating the risk of injecting sample into a high-pressure system containing liquids and gasses at or near supercritical ranges. The method improves the efficiency and significantly shortens the time of the injection process by using a check valve placed between a fill port on an injection valve and sample port where sample is injected by a syringe. After sample injection from a sample loop into a high-pressure flow stream, an injection valve is reset to receive a subsequent sample. High-pressure flow stream mixtures become trapped within the sample loop when the valve is reset. The check valve prevents the mixtures from expanding into the sample port and blowing out a syringe and flow stream mixtures from the fill lines.

Abstract: A computer implemented process which utilizes actual received signal level data gathered from closely spaced locations covering an entire CDMA system to calculate interference levels at each location, determines those base stations which most probably communicate with a mobile unit at each particular location, compiles a list of neighbor base stations for each base station at each location throughout the system, and determines the transmit power necessary for each base station to communicate with a mobile unit at each location, calculates interference levels at each base station, and determines the transmit power necessary for a mobile unit at each location to communicate with each base station which most probably communicates with a mobile unit at that particular location.

Abstract: A fractionated sample collection process and device having at least one pressurized chamber used to gather and store liquid samples generated from a flow stream containing a mixture of highly compressed gas, compressible liquid, or supercritical fluid and a relatively incompressible liquid. A bank of multiple collection chambers is secured together in a frame to form a cassette unit. Each collection chamber may house a replaceable liner such as a test tube vial, to hold a fractionated liquid phase sample. After filling with sample, a collection chamber is returned to a clean state and ready for refilling with a new sample by manually or automatically replacing the liner.

Abstract: A computer implemented process which determines those base stations which most probably communicate with a mobile unit, determines a probability for each base station to communicate with a mobile unit at a location based on the actual received signal level compared to the interference level of signals received at the location, then computes for each set of base stations a probability of that set of base stations communicating.

Abstract: A safety switch for a lamp is disclosed. The safety switch comprises a pair of electrodes having cylindrical shapes. Each electrode comprises an internal face with a conical cavity therein. The electrodes are arranged so that they are adjacently mounted with an aperture formed between the two conical cavities. In addition, there is a metal ball placed within the conical cavity. The metal ball forms a connection or disconnection of the electrodes. In one embodiment of the invention, the electrodes are horizontally mounted, and when the lamp is displaced from an upright position, the ball rests along the aperture formed between the two electrodes, thereby providing a connection of the electrodes and power and luminescence to the lamp. When the lamp is displaced from the upright position, the ball moves away from the aperture, thereby disconnecting the electrodes and power and luminescence to the lamp.
