摘要:
A method of measuring the quantity of an admixture in ready-mixed concrete comprises the steps of collecting volatile components generated from the admixture, measuring the concentration of the collected volatile components, and deriving the quantity of the admixture in the ready-mixed concrete from the measured concentration of the volatile components. An apparatus for executing this method comprises a detecting probe and a main measuring unit. The probe includes a gas collecting section and a gas sensor. The main measuring unit for carrying out arithmetic operations on detection information received from the detected probe, and includes a controller for microprocessor the operation of the entire apparatus, and a display for displaying the detected information received from the microprocessor.

摘要:
A device and a method for fusing biological cells. The device is formed by a chamber having a tube for containing a cell suspension and a cover for sealing the tube. The chamber is provided with a lower electrode having a smooth and flat surface for contacting the cells precipitating in the cell suspension, and an upper electrode opposite to the lower electrode. The lower electrode forms the inner bottom surface of the tube. The upper electrode is inserted in the cover to enter the tube. The chamber is centrifuged to form the layers of cells on the lower electrode at the bottom of the tube. Then, a predetermined ac voltage is applied across the upper and lower electrodes to fuse the cells efficiently. Such a device and method are useful for the production of monoclonal antibodies or giant cells.

In order to have the number of times of signal measurements in a phase encode direction or a readout direction and raise the speed of imaging, the following steps are performed by way of example:(i) For a measurement region E required by a conventional method, any desired partial region E.sup.+ is set (here, the combination between the region E.sup.+ and a region obtained by moving the region E.sup.+ in point symmetry with respect to the origin of a measurement space includes the region E).(ii) A signal h.sup.+ is measured on the region E.sup.+.(iii) An image is reconstructed from the signals h.sup.+ on a region neighboring the origin, thereby to obtain a phase image .theta..(iv) A reconstructed image is obtained by a predetermined computation employing .theta..
摘要:
A soybean hydrolyzate is disclosed. The hydrolyzate is of a high nutritional value and excellent in protein absorbability. Moreover, it is free from bean-like or grass-like smelling that is characteristic of soybean, as well as from bitter taste. Consequently, the hydrolyzate is very valuable food as protein source.The hydrolyzate is characterized by that the soluble fraction of the hydrolyzate contains amino nitrogen in an amount in the range from 5 to 20%, preferably from 10 to 15% of the total nitrogen of said fraction. The hydrolyzate is prepared by pulverizing soybean, adding water to the pulverized soybean to form a slurry of a solid content in the range from 1 to 20%, heating the slurry at a temperature from 60.degree. to 100.degree. C. for a period from 5 to 180 minutes, homogenizing the slurry under a high pressure and hydrolyzing the homogenates with a neutral protease produced by Bacillus subtilis.

An ignition system of the type incorporating, instead of the usual distributor, high-voltage rectifier diodes connected between the secondary winding of an ignition coil and respective spark plugs. In response to voltages developed in the secondary winding in its opposite directions the diodes function to cause discharges at the spark plugs in the firing order of the engine. Each diode is composed of a multiplicity of laminated silicon rectifier diode chips each having a reverse breakdown voltage in the range of 400-850 volts. The reverse breakdown voltage of each diode is 1.1 to 1.8 times the maximum discharge voltage of the spark plugs. Thus constructed, the diodes can well withstand overvoltages that may develop in the secondary circuit of the ignition system.

Polymers or copolymers of norbornene derivatives can be produced by contacting in the presence or absence of an inert solvent at least one norbornene derivative substituted by at least one polar group selected from the group consisting of ester, ether, nitrile, amide, imide, acid anhydride, halogen, and silyl, or by at least one substituent having one of said polar groups; or a combination of said norbornene derivative with at least one member selected from the group consisting of cycloalkenes having no polar substituent and polymers having olefinic carbon-to-carbon double bonds; with a catalyst consisting essentially of (a) at least one coordination compound of W or Mo, the oxidation number of which is 2, 1 or 0, (b) at least one titanium tetrahalide and, if necessary, (c) at least one compound selected from the group consisting of componds having an electron-accepting .pi. bond, N-halogen-substituted cyclic acid imides, sulfides, sulfoxides and phosphines. The above-mentioned catalyst is more active, cheaper, and easier to handle than the conventional catalysts containing organoaluminum compounds.
