摘要:
A negative electrode mixture layer containing CMC and a hydroxy group-modified PVP. The mass ratio of CMC is greater than that of the hydroxy group-modified PVP. The hydroxy group-modified PVP has low affinity with a solvent for a solvent-system slurry that forms an inorganic particle layer. Adhesion strength is prevented from degrading after forming the inorganic particle layer on the negative electrode mixture layer.

A linear driving device that reduces a cogging force with a simple structure as opposed to a drive mechanism having an existing structure, deals with a plurality of cogging waveforms having different periods, and suppresses not only the cogging force but also pitching that is vertical oscillation. The device has a structure provided with a plurality of magnet arrays in which permanent magnets having different polarities are alternately and rectilinearly arranged in the same direction, and a plurality of coil modules having a plurality of teeth and slots fitted with armature coils. The arrangement distance between the coil modules disposed along the displacing direction of each of the magnet arrays equals the sum or remainder of the length corresponding to a half of any one of periods possessed by the cogging force generated when the coil modules move by one magnetic pole and an integer multiple of the length of a magnetic pole pair. The coil modules are connected to each other by a connecting member, and the connecting member makes relative motion along the magnet arrays.

摘要:
An AC drive circuit for exciting the transducer of an ultrasonic level gauge. The circuit includes a gate-controlled astable multivibrator that generates pulses of constant amplitude and constant frequency. These pulses are applied to a counter arrangement adapted to equalize the total amount of positive and negative half waves in the AC drive power derived from the output of the astable multivibrator.

Disclosed is a thermostable DNA polymerase preparation which can illimitably reduce the risk of false positivity in the detection of a subject microorganism utilizing a gene amplification reaction and therefore enables the selective amplification of DNA for detecting the subject microorganism even when the amount of the subject microorganism is small and therefore the amount of DNA collected therefrom is extremely small, and can be produced at a reduced cost. Also disclosed is a method for quantifying or quantifying/identifying a subject organism to be detected rapidly, conveniently and with high sensitivity using the preparation of the present invention.
