Title: Frequency sweep oscillating device
Inventor: KOBAYASHI MORIYUKI
IPC: H03B23/00
Filed: 1977-10-13
Abstract: PURPOSE:To ensure the automatic and optional variation of the velocity whose frequency is changing and then to apply the variation effectively to the adjusting work and the like, by varying the action setting voltage of the operational amplifier to obtain the saw-tooth wave whose slope is varied at an optional time point. CONSTITUTION:Saw-tooth wave 15 and gate signal 14 are applied to input terminal 1 and 6 respectively. When the voltage emerged at variable resistor 4 of wave 15 becomes identical to set voltage v4 at time ta, operational amplifier 2 operates to produce output 16 voltage. As a result, transistor Tr9 is turned on and the charge stored in capacitor C10 is discharged via Tr9. Thus, the voltage applied to the in- phase terminal of operational amplifier 11 is lowered down as shown by waveform 18 to become low voltage 18 when becomes identical to set voltage v5 at time tb. Then the waveform identical to waveform 18 emerges at the output of amplifier 11 to be supplied to the antiphase terminal of operational amplifier to obtain waveform 19 at output terminal 13. If waveform 19 is applied to the oscillator circuit featuring the sweep frequency, it is possible to generate the sweep signal whose frequncy changing velocity between ta-tb is faster than its before and after periods.

Title: Magnetic head
Inventor: WATANABE YOSHIHIKO
IPC: G11B5/60
Filed: 1988-05-20
Abstract: PURPOSE:To prevent the wear of a medium and a magnetic head and to easily work a supporting spring and form the head by providing a ball body, which is freely rotated and reduces the slide resistance to the medium, on the surface facing the medium of a magnetic head slider which records and reproduces information while sliding on the medium.

Consequently, the contacting area between this surface 1 and the medium is considerably reduced in comparison with conventional that. Thus, the wear of the head and the medium is prevented at the time of sliding the head on the medium. It is unnecessary to float the head as conventional, and the shape of the supporting spring supporting the head is simplified, and forms of the supporting spring and the head are simplified.

Title: Magnetic recording medium
Inventor: KAMATA AKIRA
IPC: C09D5/23
Filed: 1989-05-17
Abstract: PURPOSE:To improve the output in a high-density recording system and to decrease the number of drop-outs by specifying the light wave interference type three- dimensional surface roughness on the magnetic layer surface side of a nonmagnetic base and the light wave interference type three-dimensional surface roughness on the surface opposite to the magnetic layer. CONSTITUTION:The light wave interference type three-dimensional surface roughness RaI on the magnetic layer surface side of the nonmagnetic base is specified to 0.3 to 4.0nm, P10 to 1 to 20nm and the coarse projection density PDO to <=50pieces/100cm<2>. The light wave interference type three-dimensional surface roughness RaI on the surface opposite to the magnetic layer is specified to 4.0 to 9.0nm and P10 to 30 to 100nm. Namely, the surface roughness on the magnetic layer surface side is adjusted within the range where the base surface roughness does not remain on the magnetic layer surface and the coarse projection density is so lowered as not to generate the drop-outs. The back surface side is formed to such surface roughness at which the degradation in S/N is obviated even when the magnetic tape is wound during the production process and the surface roughness of the back layer transfers to the magnetic layer surface. The magnetic conversion characteristics (output, C/N) are improved in this way and the drop-outs are decreased.
