    摘要： An optical recording system for high recording density has been found for a system which uses a heat-meltable recording medium which is melted by illuminating the same with a laser beam according to the data to be stored. The spacing between adjacent pits on the recording medium is less than the diameter of the laser beam, and then, each pit overlaps partially with the succeeding pit on the recording medium. In spite of the overlap of the pits, the recorded data can be read out by reading only the non-overlapped portion of the bank of a pit. The spacing between the pits is preferably in the range between 1/3 and 1/2 of the diameter of the laser spot so that the recording density is at least two times as high as a prior recording medium.

    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.

    摘要： It is an object of the invention to provide a current sensor apparatus that reduces measurement errors resulting from variations in a position of a current path passing through the space inside a magnetic yoke. 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). The magnetic sensor element (4) detects a magnetic field in the gap (3) generated by a current flowing through the current path (1) to measure the current flowing through the current path (1). The current sensor apparatus further comprises a magnetic field interrupter (5), placed between the current path (1) and the gap (3), for interrupting a magnetic field corresponding to a magnetic flux generated by the current passing through the current path (1) and not passing through the magnetic yoke (2), so that the magnetic field would not reach the magnetic sensor element (4).

    摘要： An oscillator circuit includes a gate G.sub.11 of C-MOS type (Q.sub.1, Q.sub.2, and the like) having the function of increasing an operating current i with increasing operating frequency. A humidity sensor HS changing electric impedance thereof in accordance with humidity is arranged in part of the oscillator circuit. The oscillator circuit converts a change in humidity into a change in frequency, causes the gate G.sub.11 to convert the change in frequency into a change in operating current i, and outputs the converted change in operating current i. Further, in order to increase the change in operating current i due to the change in frequency, a series circuit consisting of a capacitor C.sub.13 and a resistor R.sub.17 is connected to the gate G.sub.11 as a capacitive load.
