摘要： PURPOSE: To obtain a high-quality magnetic recording medium which decrease spike noise in particular with good productivity by providing a vertically magnet izable layer consisting essentially of Co-Cr on a soft magnetic layer which has the crystalline phase part of the extent to permit detection by an X-ray diffraction method or above and the greater part of which is amorphous and which is formed on a nonmagnetic substrate.
CONSTITUTION: The soft magnetic layer of Co-Zr, Co-Cr-Zr, etc. contg. Co is formed by a sputtering method on the substrate consisting of a polyester film, etc. in such a manner that the greater part deposited with the crystalline phase part of the extent to permit the detection by the X-ray diffraction method or above is of an amorphous phase. The Co-Cr layer is formed on such soft magnetic layer by maintaining the crystal orientation angle thereof in the direction perpendicular to the layer plane. The crystalline phase of the soft magnetic layer is thus provided to the detectable level in the above-mentioned manner and the quick formation of the magnetic recording medium which decrease particularly the spike noise and has the excellent vertical orientability of the Co-Cr layer thereon is thus made possible with the smaller required number of targets.

摘要： PURPOSE: To prevent a waste of dead time by detecting an unrecorded part of a magnetic tape while reproducing it and mounting an automatic fast feed equipment which switches a unit to a fast feed mode when the unrecorded part continuous for a prescribed period.
CONSTITUTION: A part of the output from a reproducing head 1 is converted to a direct current in an integrating circuit 3 and inputted into an unrecorded part detection circuit 4, which outputs a detection signal 5 to a timer 6 when no direct current signal is inputted. Receiving the detection signal 5, the timer 6 outputs a fast feed signal 7, which gets into a system component 8 to switch a unit to a fast feed mode. Then, when a tape is transferred to the tape end and a transparent part at the tape end appears, an infrared-ray sensor 9 detects it and sends a reverse signal 10 to the system controller 8. Receiving the reverse signal 10, the system component 8 automatically reverses the unit to initiate the reproduction of recorded contents on the other side.

CONSTITUTION:A clip circuit 12 clips and eliminates a portion of a synchronizing signal Hs of a reproduced luminance signal (b) clamped by a clamp circuit 11 to output a luminance signal (c) having the video signal Sv only. On the other hand, a synchronizing separator circuit 13 uses the clamp circuit 11 to extract separately only the synchronizing signal Hs from the reproduced luminance signal (b) clamped by the clamp circuit 11. A waveform shaping circuit 14 is, e.g., a saturation amplifier circuit, a signal (d) being a synchronizing signal only extracted separately by the synchronizing separation circuit 13 is subject to saturation amplification, the rounding of synchronizing signal Hs like a signal (e) is eliminated to form a complete rectangular pulse waveform. A gain adjusting circuit 15 adjusts the gain so that the peak value of the signal (e) reaches a prescribed value as the synchronizing signal and gives the result to a mixing circuit 16.

摘要： PURPOSE: To obtain a microphone which is highly sensitive and has an excellent frequency characteristic even at a high temperature by constituting a tension ring and electrode with metal having a low line expansion ratio and then constituting other composition parts with metal with a line expansion ratio larger than that of the former metal.
CONSTITUTION: All composition parts expand as temperature rises. A tension ring 10 pushes up a vibrating film 5 upward the upper surface of a vibrating film 1st fixed ring 4 to give a certain tension to the vibrating film 5. Here, since the metal with a line expantion ratio smaller than that of the vibrating film 1st fixed ring 4 is used, their expansions will not be similar, and the extension in the cylindrical direction of the tension ring 10 due to the rise in temperature is smaller that of the vibrating film 1st fixed ring 4. Thus the tensile force given to the vibrating film 5 by the tension ring 10 is smaller compared with at room temperature, and the extension of the vibrating film due to cleep together with the rise in temperature is also smaller.

摘要： PURPOSE:To prevent the abrasion of a high-permeability thin film and to keep the precision obtained when a pattern is formed by forming a highly abrasion-resistant protective layer to cover the first reinforcing member, and then joining the second reinforcing member. CONSTITUTION:A high-permeability thin film 5 is sputtered on the first reinforcing member 12, and then a protective layer 13 of silicon dioxide is formed to cover the thin film 5. The surface of the protective layer 13 is joined to the second reinforcing member 12' having almost the same structure as the first reinforcing member 12 through a joining layer 14 to form a main magnetic pole. Consequently, the abrasion of the high-permeability thin film 5 in a polishing stage or by the traveling of the recording medium is prevented, and the width and thickness of a track are not changed. Accordingly, the precision obtained when a pattern is formed can be maintained for a long period.

摘要： PURPOSE:To apply a device to an LL device to obtain a device convenient for use by selecting properly a repeat time for repeated reproducing in accordance with the operation state of a single operating means such as a push-button, namely, the method of the operation. CONSTITUTION:If the blank part of reproducing is detected during rewinding by a detecting circuit 33, the high level is inputted to a differentiating circuit 20 and is impressed to AND gates 24 and 25. When the depression of a push-button 16 is released, the differential pulse is inputted as a high-level pulse to the reproducing terminal of a control circuit 9, and a tape runs at a certain speed to obtain a reproduced signal. When the push-button 16 is depressed during reproducing, the tape is rewound, and reproduced words are repeated during rewinding. If the push-button 16 is depressed when the blank part is detected, tape running is stopped temporarily, and the tape is run at a certain speed to set the reproducing state when the push-button 16 is released. Consequently, reproduced words can be repeated during the temporary stop time, and the time of release of the push-button 16 is selected to select the repeat time.
