摘要： A simple heat mode optical recording system uses a laser beam comprised of a first laser beam and a second laser beam. The energy density of each beam is less than the threshold level for effecting the recording data on a recording medium, but the sum of the energy density of the two beams exceeds the threshold level. The second beam functions to pre-heat the recording medium, and is implemented by a powerful inexpensive LED laser, and the first beam functions to write and/or read data and has a sharp area to increase the storage capacity. Those two beams are focused on the recording medium by using a single focusing control means.

摘要： Disclosed is a magnetic head used for a vertical magnetizing system comprising a core having a pair of leg portions and an auxiliary magnetic pole which is arranged so as to face both leg portions. A closed magnetic path is formed by the core and the auxiliary magnetic pole. A sharp edge is formed at each end of the leg portions. A magnetic recording medium passes through the gap between the sharp edges and the auxiliary magnetic pole. When the magnetic recording medium passes through the gap, a high density magnetic recording operation is performed by the magnetic field produced by each sharp edge. Moreover, the recording operation can be effectively carried out due to the closed magnetic path and the recording magnetic field magnetized on the magnetic recording medium can be read out by using the same magnetic head as the magnetic head which is used for the recording operation. In an embodiment of a magnetic head of the invention, a magnetic thin film is coated on each surface of the side walls of the leg portions.

摘要： It is an object of the invention to provide a magnetic sensor apparatus and a current sensor apparatus each of which incorporates a fluxgate element for reducing an offset voltage and reducing variations in offset voltage. A drive section for exciting a sensor coil (2) includes a self-excited oscillation circuit having a resonant circuit part of which is made up of the sensor coil (2). The self-excited oscillation circuit includes an npn transistor (21) and a pnp transistor (31) that are amplifier elements used for continuing oscillation. The npn transistor (21) operates when an oscillation wave is on the positive side. The pnp transistor (31) operates when an oscillation wave is on the negative side. In the self-excited oscillation circuit, clamping of oscillation waves similarly occurs on both positive and negative sides. Therefore, the oscillation waveform has symmetrical positive and negative portions or has minor asymmetry if any.

The current sensor apparatus comprises a ring-shaped magnetic yoke (2) surrounding a current path (1), part of the yoke having a gap (3), and a magnetic sensor element (4) placed in the gap (3) of the magnetic yoke (2).

摘要： An absolute humidity meter in which a humidity sensor changes an electrical impedance thereof-exponentially with respect to the relative humidity. A z-f converting circuit (impedance to frequency ) generates a pulse signal corresponding to the impedance. A time constant control differentiating circuit has an impedance of a voltage control variable impedance element changed exponentially by a control voltage, and outputs a differentiated signal obtained by differentiating the pulse signal. A waveform shaping circuit outputs a pulse signal train obtained by binary-valued the differentiated signal. An integrating circuit causes a first integrating circuit to obtain the control voltage by integrating the pulse signal train and a second integrating circuit to obtain an output voltage of a relative humidity signal by integrating the pulse signal train, and obtains an absolute humidity signal by causing at least one of these integrating circuit to control the control voltage or the output voltage with increasing temperature.
