Abstract: Potassium hexatitanate fibers having a tunnel struc­ture and a free potassium content of 5 ppm or less can be produced by mixing together a titanium containing compound and a potassium containing compound in a ratio represented by the formula K₂O·nTiO₂ (wherein n = from 2 to 4); firing the mixture at 900 to 1,200°C to produce mass of potassium titanate fibers; dipping the mass of product in either cold or hot water to disintegrate the mass of potassium titanate fibers into individual single fibers; adding an acid to the slurry to adjust the pH value to 9.3 - 9.7, thereby changing the composition of the potassium titanate fibers so that the molar ratio of TiO₂/K₂O is in the range of from 5.95 to 6.00; heating the fibers at 950 to 1,150°C for 1 hour or more; and washing the fibers with an acid. The potassium hexatitanate fibers, which have a minimal free potassium content, i.e., 5 ppm or less, can be suitably used as a reinforcing material for polyester thermoplastic resins, polyphenylene sulfide resins, liquid crystal polymers, aluminum alloys, magnesium alloys and so forth, all of which are easily affected by free potassium.

Abstract: In a battery-driven computer system, flip-flop cir­cuit (13) selects one of two switches (14, 15) for switching a power supply to the computer system (1) in accordance with the terminal voltages of batteries (17, 18) detected by detecting circuits (11, 12). When the first switch (14) is switched on, the first battery (17) coupled to the first switch (14) supplies its power to the computer system (1). In this case, the second switch (15) is switched off and the power from the second battery (18) coupled to the second switch (15) is not supplied to the computer system (1). When the ter­minal voltage of the first battery (17) becomes less than or equal to a low battery voltage, LED (3) is caused to blink in order to inform an operator of a low battery condition. When the terminal voltage of the second battery (18) is greater than the low battery voltage, however, power from the second battery (18) is supplied to the computer system (1). In this manner, batteries (17, 18) can be automatically switched without interrupting the operation of the computer system (1).

IPC: C12Q1/6888
Filed: 1989-04-21
Abstract: Nucleic acids are extracted from biological samples by pretreating the samples to release the nucleic acids and contaminating materials into an aqueous phase. Optionally, the samples may be extracted with an anionic detergent in an organic solvent prior to release of the nucleic acids. The aqueous phase is then combined with an organic phase in the presence of a cationic detergent capable of forming water insoluble complexes with the nucleic acids. Usually, a chelant will also be combined with the aqueous phase. The complexes are preferentially partitioned into the organic phase and are thus separated from the contaminating materials which remain in the aqueous phase. The nucleic acids may then be transferred back to a second aqueous phase by combining the organic phase with water in the presence of an inorganic salt selected to displace the detergent cation. After separation of the organic phase, the second aqueous phase containing the nucleic acids may be used for conventional hybridization testing.
