IPC: G02B7/28
Filed: 1979-05-31
Abstract: PURPOSE: To control recording beam light so that the same information recorded with constant energy will be constant in recorded amount at any time, by exercising  control over a light source by providing a photoelectric converter which receives the reflected light of focus beam light from a disk surface and then generates an output signal corresponding to the photoreceiving position.

Differential amplifier 31 outputs signal S 3  corresponding to the difference in level to drive voice coil 25, which sets condenser 24 at an adequate position and this output signal S 3  is also led to laser oscillator driver 35 to control the energy of output beam light l 0 , so that fusion deformation will come into effect on a recording surface with invariably constant energy corresponding to the extremely small change in distance between the disk 11 surface and condenser lens 24.

Abstract: PURPOSE:To improve the reliability of measured values by introducing the ratio of magnetic field energies which are generated in a space for inserting a ferromagnetic body and a space outside a detection jig and taking into account the energy distribution in the magnetic field generated by the jig. CONSTITUTION:A ferromagnetic body having thickness t and width w is inserted into a detection jig of a parallel line construction which has line length a, width b and space c as to match a measuring system and of which one end is closed, in order to measure the impedance thereof. Then, when it is assumed by applying an input signal to a detection jig that a ratio E2/E1 of the magnetic field energies E1 and E2 generated in the space for inserting the ferromagnetic body and a space outside the detection jig is alpha, the real number component (mu'mu0) and the imaginary number component (mu''/mu0) of the complex relative permeability (mu/mu0) are evaluated by using two formulae, mu'/mu0=(L/L0/1).(1+alpha).S0/S and mu''/mu0={(R-R0)/(wL0)}.(1+alpha).S0/S. In these formulae, L and R show the inductance and resistance when the ferromagnetic body is inserted, respectively, and L0 and R0 show the inductance and resistance when the ferromagnetic body is not inserted, respectively, w shows the angular frequency, and S0/S shows (bXc)/(tXw).

Filed: 1985-03-29
Abstract: PURPOSE:To decrease the time constant and the number of components by introducing a bias voltage to a varactor diode via a resistor or an inductor. CONSTITUTION:In inputting a DC output voltage Vout of an operational amplifier IC1 to the varactor diode CD1 as a bias voltage through a resistor R5, the time constant relating to the leading of the FM modulation by the diode CD1 is determined by an output impedance R of the amplifier IC1, a capacitance C'3 of a capacitor C3 to pass through the oscillation frequency, a resistance value R'5 of the resistor R5 and a capacitance CD'1 of the diode CD1. Further, a separate power supply Vcc1 is impressed always to the amplifier IC1 to keep the voltage of the diode CD1 constant at all times. On the other hand, a power supply Vcc2 gives a separate power to the transmission system or the like. Thus, the leading time is decreased and the increase of the time constant and the number of component is suppressed.
