Title: Optical head device
Inventor: KATAYAMA RYUICHI
IPC: G11B7/135
Filed: 1990-06-13
Abstract: PURPOSE:To obtain an optical head device which has a position error of an optical spot smaller than the allowable value on an optical recording medium by using two specific prisms. CONSTITUTION:A semiconductor laser 1 is provided together with a collimator lens 2, the 1st and 2nd prisms 4 and 5, on objective lens 10, and a photodetector 22. The incident and refracted angles are referred to as PHI1 and theta1 on a 1st incident surface of a light beam with the incident and refracted angles referred to as PHI2 and theta2 on a 2nd incident surface respectively. Then the increments of the refraction rates of both prisms 4 and 5 are referred to as DELTAn1 and DELTAn2 respectively when the wavelength of the light beam increases by 1mm at a point near the center wavelength. Under such conditions, the conditions of an equation I are satisfied. As a result, the angle error value due to the change of the wavelength of the light beam is reduced in a prism radiation state. Then the position error of an optical spot can be reduced less than the allowable value on an optical recording medium 12.

Title: Resetting method for tuning voltage
Inventor: MORIKAWA NARIKAZU
IPC: H03J7/02
Filed: 1989-06-16
Abstract: PURPOSE:To attain pull-in to a desired tuning point even when a tuning voltage rises at the time of resetting by a lower limit (1st level) and an upper limit (2nd level) to specify an analog AFT pull-in range, and setting the tuning voltage in the specific order in response to the quantity between the AFT output voltage and the 1st level. CONSTITUTION:When the tuning voltage is deviated from a normal value [AFT output voltage] <5/16DD, the tuning voltage is decreased. Then a channel selection control section 3 observes an output of a window comparator 6 and in the case of [AFT output voltage] >10/16VDD, an output of a station presence/ absence discrimination circuit 5 is observed, and in the case of the station presence, the tuning voltage is increased. When the relation of [AFT output voltage] <5/16VDD is discriminated, the tuning voltage is decreased. Then the analog AFT circuit applies pull-in operation to the tuning point with the operation of the AFT circuit in a tuner pack 9. Thus, even when the tuning voltage is deviated upward due to temperature drift or the like, the normal tuning point is set.

Title: Bipole signal discriminator circuit
Inventor: YOKOI YOJIRO
IPC: B61L1/18
Filed: 1987-06-24
Abstract: PURPOSE: To prevent occurrence of malfunction because of noises generated in a bipolar signal discriminator circuit of a train sensor, etc., by feeding back part of an oscillator circuit output signal to the negative power supply, and carrying out a computation of adding.  
     CONSTITUTION: When bipolar signals repeating positive and negative polarities continually are supplied to terminals S 1 , S 2 , a voltage convertor circuit 1 supplies +Ve and -Vg to the terminals 2a, 2b of an oscillator circuit 2, respectively, which now emits an oscillation signal F with a specified frequency. Part of this oscillation signal F is fed back to the terminal 2b through the n 3  winding of transformer T and a diode D 4  and added to the terminal voltage -Vg of a capacitor C 1  to retain the terminal 2b in negative condition and continue the oscillation, and the oscillation signal F emits a rectification output from terminals S 3 , S 4  through a rectifier circuit 3. Because repeated positive and negative are not generated continuously even though a positive or a negative noise is fed, the oscillator circuit 2 will not oscillate. Thus malfunction due to noises can be prevented.
