摘要:
An improved magnetic head enables to reduce a crosstalk values without degrading head wear characteristic of the magnetic head when it is used as a pair of magnetic heads in a magnetic head assembly. The magnetic head has a first and second core sections, each containing at least a magnetic core. The first and second core sections forms a magnetic gap between the respective magnetic cores and a head-tape contact surface by being abutted at distal end surface thereof. The first core section has an approximately L-shaped configuration. The first core section has a head-tape contact core part for forming a part of the head-tape contact surface of the magnetic head and a straight core part extending in an opposite direction of the head-tape contact surface from the head-tape contact surface. The second core section has an approximately C-shape configuration to allow a winding to be provided around the second core section. Length of the head-tape contact core part is made longer than a length of the straight core part in a tape running direction.

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.

摘要:
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.
