Title: Optical pickup device
Inventor: KURIHARA TOSHIHIKO
IPC: G02B7/00
Filed: 1985-08-09
Abstract: PURPOSE:To prevent the generation of the undesired resonance of a suspension spring and to eliminate the adverse influence to the reproduced signals, by supporting oscillatably an objective lens by means of two pairs of suspension springs set at both sides of the objective lens with a space secured in the verticall directions and in parallel with each other. CONSTITUTION:An objective lens 9a is kept parallel with its optical axis when the lens 9a is driven for execution of both the focus control and the tracking control. For this purpose, a flange 9d is supported by a pair of suspension springs 9e and 9f which are set in parallel at both right and left sides with a vertical space secured. Two plate type conductors 9i forming the springs 9e and 9f respectively have different widths and different resonance frequencies. Thus both springs 9e and 9f have difficulties to produce resonance with a specific frequency. This can reduce the generation of undesired resonance.

Abstract: PURPOSE:To shorten the length between a magnetic head and a magnetic circuit to make a carriage small in size and light weight by constituting a mechanism so that the leaked magnetic flux from the magnetic circuit is reduced near the magnetic head. CONSTITUTION:Yokes 10a and 10b have magnetic gaps 11a and 11b to form an E-shape. Respective magnetic gaps have magnets 13a and 13b, and the magnetic flux forms two magnetic loops, which are symmetrical with respect to joined surfaces, in yokes. A notch 14 is formed in the center part of the E-shaped magnetic circuit consisting of yokes, and a carriage 15 is stored movably in this notch 14. The carriage 15 has flexures 17 supporting heads 18. Thus, a plane of a maximum leaked magnetic flux, namely, a plane orthogonal to the magnetic flux of magnetic gaps is made parallel with a line connecting magnetic disc 12. Magnetic heads 18 are placed between two magnetic loops generating the leaked magnetic flux, and the line connecting heads does not intersect the plane of the maximum leaked magnetic flux, and therefore, the leaked magnetic flux near magnetic heads 18 is reduced, and the length between the magnetic circuit and magnetic heads 18 can be shortened.

Title: Fm multiplex data broadcast receiver
Inventor: KURODA TORU
IPC: H04H1/00
Filed: 1988-07-18
Abstract: PURPOSE:To reduce high frequency disturbance with a simple circuit by attenuating at least one frequency among frequencies being three times, four times and five times of a pilot signal frequency. CONSTITUTION:For example, a band pass filter 1 uses a frequency 85.5kHz being 4.5 times the frequency 19kHz of the pilot signal as the center frequency in an FM multiplex data broadcast receiver receiving an FM broadcast wave having a carrier of 3.5 or 4.5 times the pilot signal frequency. Moreover, a 76kHz notch filter 3 eliminates a disturbing wave component being 76kHz and its surrounding frequency from an output signal 2 of a filter 1 and a 95kHz notch filter 4 eliminates a 95kHz frequency and its surrounding disturbing wave component from the output signal from the filter 3. Thus, since a data detection circuit 6 causes no unstable operation due to a disturbing wave and an error correction circuit 109 outputs a data signal 9 with a low error rate, the high frequency disturbance is reduced with a simple circuit.
