Title: Mapping detouring defective sector with disc drive
Inventor: WEVERS WILLIAM E
IPC: G06F3/06
Filed: 1986-11-20
Abstract: Electronic circuitry is provided to position the read/write heads (10) in a designated landing zone when the electrical power is removed from the drive (27). when power is removed from the drive, the stored energy of the rotating spindle motor (27) is used as a source of electrical power and timing pulses to the stepper motor (30) which drives the actuator of the disc drive. The power generated by the spindle motor as it spins down is referred to as "back EMF". A sequencer circuit (50) is provided to couple the power and clock pulses to selected windings of the stepper motor (30) in an order that will cause the stepper motor to rotate in the direction necessary to move the transducer heads (10) to a predetermined park position at the inner diameter of the disc whenever power is removed from the disc drive. Since the location of the heads at power down may not be known, the timing of the pulses in such that a sufficient number of steps will be taken to move the transducer heads to the parking zone within the time allotted even if power down occurred when the heads were at the outermost track. Step pulses will continue to be generated until the back EMF of the spindle motor is insufficient to generate such pulses. After the transducer heads are at the predetermined parking location, any additional steps will cause the actuator to contact a mechanical "inner crash stop" designed to prevent damage to the transducer heads from contact with the clamp which retains the discs.

Title: Oil feeder
Inventor: YOSHIDA TAKEOMI
IPC: B67D7/42
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To shorten oil feed time, by restricting the number of times that additional oil feed is carried out after the detection of foam. SOLUTION: An oil feed nozzle 33 has a photo-interrupter for detecting foam formed on a liquid surface due to oil feed, and an ultrasonic sensor 28 for detecting the liquid surface. The control circuit 35 of the oil feeder 21 judges whether the number of times that a liquid surface is detected by the ultrasonic sensor 28 after the start of oil feed by the valve-opening operation of the oil feed nozzle 33 has reached a preset number of times or not, and judges whether an interval between liquid-surface detections by the ultrasonic sensor 28 is within a specific time or not. When it judges that the number of times that the liquid surface is detected has reached the specific number of times and that the interval between the liquid-surface detections is within the specific time, the oil feed is stopped to stop fill-up oil feed.  Therefore, by the restriction of the number of times that additional oil feed is carried out during the fill-up oil feed, oil feed time from the start of the oil feed to the finish of the fill-up oil feed can be shortened.

Title: Amplifier circuit
Inventor: SANO YUJI
IPC: H03F1/42
Filed: 1990-10-19
Abstract: PURPOSE:To fix an arbitrary operating point even when variable impedance is varied by connecting a voltage source to the variable impedance for a gain setting in series. CONSTITUTION:A voltage source 29 for operating point fixing in connected in series to a variable resistor 23R for driving adjustment in a video amplifier circuit 2R. A constant operating point can be secured without depending on the resistance value of the variable resistor 23R for driving adjustment by connecting the power source 29. However, it is required to set voltage VCR of the voltage source 29 at the voltage almost equal to the emitter voltage of a transistor 22R when cutoff adjustment is performed. By setting the voltage VCR in such way, it is possible to decrease a current that flows from the emitter of the transistor 22R to the variable resistor 23R for driving adjustment to a negligible level when the cutoff is adjusted. In such a way, the operating point of this circuit can be adjusted independently for the resistance value of the variable resistor 23R.

Title: Recording and reproducing device
Inventor: KOBAYASHI JUNJI
IPC: G11B15/43
Filed: 1985-12-13
Abstract: PURPOSE:To obtain an appropriate tension corresponding to a recording tape by correcting and controlling the tape tension in accordance with a change in the travel route of the recording tape, which stems from loading a different recording tape containing cassette. CONSTITUTION:When a normal cassette is loaded, a cassette placing stand 19 is downwardly positioned with respect to a main chassis 18. A lever 24 is abutted on a stopper 26. While the tape is normally traveling, an appropriate tape tension can be attained due to elasticity preset by a spring 25. If a short- time tape cassette 11b is loaded, it is loaded on the placing stand 19, after which it is upwardly moved. At that time, the lever 24 comes into contact with a pin 27 forwardly located, and slowly rotated counterclockwise by the pin 27. Thus the spring 25 is stretched, and force pulling at left with respect to an arm 4 increases. Thus an appropriate tape tension can be obtained irrespective of a tape cassette.
