Title: Electric power supply device for rolling stock
Inventor: HARADA EIJI
IPC: H02J7/14
Filed: 1989-03-29
Abstract: PURPOSE:To raise the generation efficiency of an armature coil by providing with a setting means to set the 2nd voltage supplied from an AC generator at the 1st voltage and a battery to supply the above 1st voltage from this setting means. CONSTITUTION:When a pole core of a rotor 3 begins to rotate, the N and S poles of an electromagnet composed of a pole core 31 and a field coil 32 alternately come close to and go away from a stator coil 42 of a stator 4 in an AC generator 2. Almost constant 2nd voltage is generated to the stator coil 42 as the rotor 3 of the AC generator 2 rotates almost constantly on account of the rotation of an output shaft 63 of a hydraulic motor 6 on the best speed. The 2nd voltage generated at the stator coil 42 is reduced by predetermined voltage by a transformer and is sent to a rectifier 45 after it was set to the voltage higher than the 1st voltage. The 1st voltages converted into DC by the rectifier 45 and supplied to the battery through a B terminal 46.

Abstract: PURPOSE:To easily identify a PB signal inputted from a line wire opponent side during the message reproduction by executing a gain control in accordance with an input level when a message given from a line wire is sound-recorded and sound recording with a fixed gain set beforehand to the message given from an extension. CONSTITUTION:When a message given from a line wire 1 is soundrecorded, an AGC circuit for sound recording executes the gain control so that the sound recording can be always executed approximately at a constant level in accordance with the input level of the said message under the control of a control part 11. On the other hand, when an automatic answering telephone message for the line wire is sound-recorded from an extension telephone set 5, the section between the extension telephone set 5 and a voice sound recording reproducing part 9 is connected through a calling switching part 8 and it is stored to a voice memory 21. In this case, the AGC circuit 22 for the sound recording is amplified by a fixed gain set beforehand. Thus, it is prevented that a white noise is sound-recorded at the time of silence and the reduction of the quality of a message sound for an opponent and the reduction of the receiving capacity of a PB signal are not generated.

Inventor: TAGAMI MASAMICHI
IPC: G11B5/851
Filed: 1985-04-12
Abstract: PURPOSE:To narrow a track and to stabilize the recording and reproduction by making the vertical anisotropy of a magnetic body in a data track in the title magnetic recording body larger than the vertical magnetic anisotropy of a guard band track between the data tracks. CONSTITUTION:A nonmagnetic thin film such as a thin film 1 of Cu, Cr, etc., is formed by sputtering, etc., as an undercoating effect on a substrate 4 to reduce the vertical magnetic anisotropy of a vertical magnetic recording medium 10 and then the vertical magnetic recording medium 10 is formed. A Co alloy typified by CoCr is used as the medium. Accordingly, the vertical magnetic anisotropy of the magnetic film 10 in a guard band track 2 between data trucks is reduced and the recording density characteristic is deteriorated. Consequently, even when data are recorded on the guard band in the high-density region in a data truck 3, the output from the region is small as compared with the output from the data track 3 by tracking deviation, unerased noises due to the crosstalk and tracking deviation can be controlled. Consequently, the track is narrowed and the recording and reproduction can be stabilized.
