Patent JP-2838117-B2 (JP)
IPC: G01N21/64

Granted: 1998-12-16
Abstract: Light from the pattern of spots of bands resulting from electrophoresis is detected by a two-dimensional charge coupled device (26). Visualisation of the spots or bands may be achieved by viewing in transmitted light if the material subject to electrophoresis is dyed, by fluorescent markers in the material stimulated by untraviolet, or by a scintillating material if radioactive markers are used.Preferably the charge coupled device (26) is cooled to suppress thermal dark current, improving sensitivity and dynamic range.Light can be detected from moving components during separation by electrophoresis by clocking the charge coupled device to move charge packets in synchronism with movement of the components. This means that each charge packet moves through all the elements of a charge coupled device column during the detection, resulting in automatic averaging for the detection sensitivity variations in the charge coupled device column. Further, it is thereby possible to detect each separated band or spot at the same position in the gel at different times, and thus at the same degree of resolution, instead of detecting the bands or spots at different positions at the same time.

Abstract: PURPOSE:To attain surface reform without welding defects by irradiating the surface with high density energy to melt it and then carrying out built-up welding with heat-resisting element. CONSTITUTION:A part 11 to be reformed is heated with TIG arc by using a TIG torch 12 to form a molten layer 19 by the irradiation of high density energy. Immediately after that, the build-up welding of heat-resisting element is carried out by using a plasma welder 13 to form an alloyed layer 20, which can be molten again by the high energy source. These processes are repeated twice to add the heat-resisting element. By this method, the added amount of heat-resisting element is increased, and the uniformized structure of alloyed layer having no defects is obtained.

Abstract: The invention relates to solid bodies of high-temperature superconducting material, which are bonded to solid, compact metallic conductors. In order to produce these solid bodies, high-temperature superconducting material is either fused completely, or a melt is prepared comprising the oxides of bismuth, strontium, calcium and copper and, if appropriate, antimony and lead. The solid compact metallic conductors made of silver, gold, a platinum metal or an alloy containing these metals is then partially coated with the melt, and the melt is left to solidify. Finally, the solid body obtained is annealed, together with the conductors, in a first step, at temperatures from 710 to 810 DEG C, and in a second step in an oxygen-containing atmosphere at temperatures from 750 to 880 DEG C.

Abstract: A housing construction for a gas generator comprises four structural components (14a, 16a, 64, 66) which between them define an inner cylindrical chamber (34) for an ignition charge (38) and a concentric outer cylindrical chamber (36) divided into three annular compartments (72, 74, 76) for gas generant (86) and for first and second filter/coolers (88, 90) respectively. Parts (78, 80, 82, 84) provide communication between the ignition charge, the gas generant, the filter/coolers and the outside. The housing is preferably made of aluminium in the place of steel, thereby effecting a further reduction in weight while enabling manufacture in high production rates at low cost and meeting the high reliability standards required of a safety device.

Abstract: An environment-friendly aqueous slip and mould-release agent for the manufacture of tyres and other rubber articles and a process for the moulding and vulcanization of tyres and other rubber articles are described. The aqueous slip and mould- release agent contains 0.5 to 6 wt.-% polytetrafluoroethylene, 20 to 40 wt.-% mineral fillers and at least 40 wt.-% water. It is sprayed onto the inside of the tyre blank prior to the moulding and vulcanization, so that the water contained therein evaporates, accompanied by development of a slip and release agent film. Apart from the environment-friendliness and good release effect, the new slip and mould-release agent leads, despite the high water content, to a quick evaporation of the water and thus a rapid development, desired in industrial operations, of the slip and release agent film. The excellent effectiveness of the slip and mould-release agent according to the invention results in a substantial prolongation of the life of the heating membrane used for the moulding and vulcanization.

Abstract: PURPOSE:A sucking-type cultivation tank is used to prevent the structure from becoming too large and a natural culture medium containing saccharified rice bran and phosphatidylcholine is used to enable the yeast to be used in the production of food or beverage products directly. CONSTITUTION:KOJI essence or saccharified rice bran is combined with phosphatidylcholine and the resultant culture medium and a yeast are charged in a cultivation tank 1, then the tank is tightly closed. The air in the tank is evacuated by the suction mechanism 9 and sterilized air is fed from the air feeder 6 into the culture mixture V in the tank. This condition is continued to effect yeast cultivation. Resultantly, a large scale installation becomes unnecessary and the air introduction is improved. Further, it becomes unnecessary to remove synthetic substances by centrifugation and the yeast can be safely used directly as an alcohol source in the production of food or beverage products.

A photomultiplier tube detects the intensity of light emitted by the sample fluid during the ECL measurement process. A computer control unit both analyzes the detected data and provides digital control signals to the cell unit to generate effective voltage waveforms. The digital control signals are supplied to a novel pulse width modulated digital to analog converter which outputs a ramp voltage waveform having the desired slope.

The circuit is coupled to an oscillator which provides a drive signal to a differential driver. The driver transforms the clock signal into first and second complementary drive signals. The drive signals are coupled to a field coil through a plurality of capacitors for inductively producing an output power signal. The capacitors are differentially coupled to the coil, so that each input of the coil is coupled to one of the clock signals through a separate capacitor. A bridge rectifier is coupled to the field coil opposite the capacitors for producing an output comprising a direct current element and an alternating current element superimposed on the DC element. A resistance-capacitance (R-C) filter, coupled to the bridge rectifier, provides a filtered rectifier output signal.

Abstract: PCT No. PCT/US91/09223 Sec. 371 Date May 14, 1993 Sec. 102(e) Date May 14, 1993 PCT Filed Dec. 6, 1991.An original equipment type seal for recharged toner cartridges can be installed without splitting the cartridge itself, by screening a border of "hot-melt" type adhesive, preferably wax-based, onto a strip of polyester, the adhesive being capable of softening or melting at a temperature above the softening or coagulating point of the toner powder itself, but below the softening points of the plastic components of the cartridge. The polyester seal is inserted into the cartridge with the aid of a room temperature or even cold, metallic insertion tool, preferably made of a high magnetic permeability steel. Heating this cold tool, or subsequently inserting a hot tool, will cause the adhesive to melt and seal the cartridge. In those areas of the cartridge where there is little or no significant pressure to assure firm contact with the adhesive, the insertion of a "pressure tool" incorporating a magnet, into the fill hole in the cartridge, where the magnet portion is brought in close proximity to the steel insertion tool, allows one to push and/or pull the insertion tool surface so as to bring about an intimate contact between the adhesive on the seal and cartridge surfaces to be sealed. The utilization of wax-based adhesives and a cold, and then heated, insertion tool, together with a magnetic pressure tool is the preferred embodiment, but the use of other hot-melt-type adhesives and insertion tools are possible within the purview of this invention.
