Title: Auto-focusing device
Inventor: MIYAZAWA AZUMA
IPC: G03B13/36
Filed: 1986-10-24
Abstract: PURPOSE:To accurately correct a target position without moving a lens at a certain speed by performing AF distance measurement during driving of the lens independently of the motor speed. CONSTITUTION:During driving of the lens, a driving control circuit 2 outputs an electric charge discharging pulse EE and a storage helping pulse SHA and the electric charge discharging pulse EE is generated synchronously with, for example, the rise of an encoder pulse for a certain time. Only the electric charge stored in a carrier depletion area CE of a CCD is discharged by a discharging electrode EE0 when the pulse EE is generated. The electric charge stored in the period of turning-on of the storage helping pulse SHA is saved in a storage helping electrode SHA0. Consequently, only the stored electric charge during a certain time t0 between the electric charge discharging pulse EE and the storage helping pulse SHA is saved in the storage helping electrode SHA0, and as the result of repeat of this operation, the electric charge is stored for a time Nt0 where N is the number of encoder pulses outputted in the storage period. Thus, the lens position as the reference of target position calculation is easily calculated by N/2.

Abstract: PURPOSE:To transfer a distance from the rotation center of a master magnetic disk to each magnetic information to a slave magnetic disk by positioning the master magnetic disk and the slave magnetic disk using the same chucking mechanism. CONSTITUTION:After chucking a first master magnetic disk 301 to a chucking mechanism 171 and rotating until an engaging pin 177 turns to a prescribed position, the magnetic disk 301 is arranged and fixed on a magnetic disk holding surface 113 of a first supporting part 111 by an adjustment mechanism 191. A second master magnetic disk 401 is fixed similarly. After that, a slave magnetic disk 501 is also chucked similarly, adjusted at the same position, and fixed to be lowered so that the magnetic disk 301 and the slave magnetic disk 501 are slightly contacted by the adjustment mechanism 191.

Title: Magnetic recording medium
Inventor: UEJIMA TOKUO
IPC: G11B5/738
Filed: 1985-11-15
Abstract: PURPOSE:To improve the resistance of the titled medium to wear and corrosion by forming a protective film of an Ni-Ti alloy having more than a specified thickness and regulating the total thickness of the protective film to less than a specified thickness. CONSTITUTION:The protective film is formed with the film of an Ni-Ti alloy having >=0.005mum thickness and consisting of 45-55at% Ni and the balance Ti, and the total thickness of the protective film is adjusted to <=0.5mum. When the composition of the Ni-Ti alloy exceeds the specified range, the resistance of the Ni-Ti alloy to wear and corrosion as the protective film is decreased. When the thickness of the Ni-Ti alloy film is less than the specified value, the interval between the magnetic film and a head is increased, and hence the head output is lowered, and the medium can not be used as the magnetic recording medium.

Abstract: PURPOSE: To obtain the optimal adjustment characteristics of an amplifier circuit with a relatively small supply voltage and currents by providing a serial resistance in the front stage of a signal input terminal, and supplying a voice signal through this resistance to the signal input terminal of a CMOS invertor. CONSTITUTION: A serial resistance 25 is provided in the front stage of a signal input terminal 19. The gain of a CMOS invertor 14 is decided by the serial resistance 25 with a feedback resistance 24. A voice signal whose level should be controlled is supplied through the serial resistance 25 to a signal input terminal 19 of the CMOS inverter 14. The CMOS invertor 14 is operated with a voltage less than a critical point voltage in the starting area based on a DC control voltage supplied to a supply voltage connection 21. The supply voltage is selected to be low for operating such CMOS invertor. Thus, a relatively wide adjustment range can be established at the time of the electric control or adjustment of each voice signal level by using only one CMOS inverter operating with a voltage less than the critical point voltage in the starting range.
