Patent JP-S63275007-A (JP)
Title: Magnetic head
Inventor: ISHIHARA MASAHIKO
IPC: G11B5/11
Filed: 1987-05-06
Abstract: PURPOSE:To prevent mixing of noise by providing an insulator coating a part of a coil and a conductor film coating the insulator so as to allow a noise current charging the static capacitance between the coil and a recording medium to be absorbed into the conductor film. CONSTITUTION:An insulator 22 coating part of a coil 3 and a conductor film 23 coating the insulator 22 are provided. If a potential difference due to a noise 20 is caused between a recording medium 11 and the coil 3, the noise current to charge a static capacitance 21 existing between them flows. Since the static capacitance between the coil 3 and the conductor film 23 is decreased by the insulator 22, the noise current is absorbed by the conductor film 23 and grounded through a ground wire 24. Thus, the noise current does not flow to the coil 3 and the invasion of the noise 20 to the signal reproduced by the amplifier 8 is avoided.

Filed: 1991-02-15
Abstract: PURPOSE:To allow an indicator to work when a transmission line breaks down due to a power failure 0.1-0.5 second after lightning current flows in the leg or other parts of a steel tower for the transmission line. CONSTITUTION:A coil for detecting lightning current is installed near the leg of a steel tower for a transmission line and a metal bar, that is, a detection bar is installed near the transmission line for detecting whether the line is alive or broken down due to a power failure. The output of the coil is detected by a current detector and the detected value is stored in a memory for 0.1-0.5 second. Meanwhile, the output of the detection bar indicates whether the transmission line is alive or broken down due to a power failure. The output of the memory and detection bar is inputted into an AND circuit and then a power failure is detected immediately after lightning current is detected. When the power failure is detected, an indicator works.

Filed: 1980-08-09
Abstract: PURPOSE:To automatically reduce the receiving sensitivity between channels at the time of automatic sweep, by switching the sensitivity of a high-frequency amplifying circuit in accordance with an output level of an intermediate frequency amplifying circuit. CONSTITUTION:In case of being in an aperiodic state against broad-casting, an output of an intermediate frequency amplifying circuit IF is zero, therefore, a transistor Q2 is off, and voltage across a resistance R3 is also zero. Accordingly, a transistor Q3 is also off. Therefore, in this state, a field effect transistor Q1 constituting a high- frequency amplifying circuit is in a nonoperating state, and the sensitivity of the whole radio receiving circuit is lowered remarkably. In a tuning state, a signal exceeding a certain value is outputte from the intermediated frequency amplifying circuit IF, therefore, the transistors Q2, Q3 become on, and the field effect transistor Q1constituting the high frequency amplifying circuit is operated normally.

Abstract: PURPOSE:To suppress the rise of the ambient temperature around a heater and to increase its lifetime by forming a vent opening for communicating the interior with the exterior of a far infrared ray radiator by providing a heater and the radiator covering the heater. CONSTITUTION:When a power source switch is closed, a heater 17 is energized to generate high heat, and atmospheric temperature in a far infrared ray radiator 21 largely rises. Since the interior of the radiator 21 is ventilated via an opening 21a, high temperature air is not enclosed in the radiator 21, the ambient temperature of the heater 17 and hence the surface temperature of the heater 17 is not so largely raised. Accordingly, there is no possibility of improper insulation, and the lifetime of the heater 17 can be increased. The radiator 21 made of ceramic carbon can be held in a red heating state while suppressing the rise of the ambient temperature of the heater 17 to improve visual effect and further to easily replace the radiator 21.
