Title: Disk storage having fluid bearing spindle motor, and method for detecting failure in the spindle motor
Inventor: KOTAKE SHINSUKE
IPC: H02P29/02
Filed: 2001-03-15
Abstract: PROBLEM TO BE SOLVED: To easily detect the failure in a spindle motor by monitoring a motor current that is supplied to the fluid bearing spindle motor. SOLUTION: A current sensor 17 detects a current supplied from a driver IC 12 to the fluid bearing spindle motor 13. A CPU 11 periodically reads an ambient temperature, that is detected by a temperature sensor 14 via an A/D converter 111 and refers to a temperature table 110a, thus acquiring a reference voltage value that is equivalent to the current, that is supplied to the motor 13 at the ambient temperature and when the spindle motor 13 is normal. The CPU 11 generates the reference voltage of the reference voltage value by a reference voltage generating circuit 15. A comparator 16 compares the detection value of a current sensor 17 with a reference voltage, that is generated by the reference voltage generating circuit 15. A controller 18 interrupts the CPU 11, when a failure in the spindle motor 13 is decided from the comparison result of the comparator 16.

Title: Dc-dc converter
Inventor: ISHII TAKUYA
IPC: H02M3/155
Filed: 2001-03-27
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of a step-up and step-down converter to input a DC voltage from a battery, etc., and supply a load with a controlled DC voltage. SOLUTION: In the noninverting step-up and step-down converter comprising the first, second, third and fourth switching means 2, 3, 4, 5 and a choke coil 6 and an output capacitor 7, a doubled output DC voltage as a drive voltage source is generated by the first and second rectifier and filter circuit 12, 15. Since the seventh switching means 16 connected to the first switching means 2 in parallel is synchronized with the first switching means 2 and turned on/off, the input DC voltage is reduced. Even if on-resistance of the first switching means 2 increases, a decreased on-voltage of the seventh switching means 16 compensates and the converter can be highly efficient.

Title: Control device for continuously variable transmission
Inventor: NISHIDA SUKEYUKI
IPC: F16H61/04
Filed: 2001-04-09
Abstract: PROBLEM TO BE SOLVED: To prevent generation of slip of a drive belt when rotation speed of a primary pulley is quickly reduced due to an ultra-low car speed state caused by quick speed reduction. SOLUTION: A continuously variable transmission comprises the primary pulley of a fixed pulley groove width, and a secondary pulley of a changeable pulley groove width, with a drive belt stretched between that and the primary pulley. By adjusting primary pressure to be supplied to the primary pulley, and secondary pressure to be supplied to the secondary pulley, a ratio of a winding diameter of the drive belt is changed. When the rotation speed of the primary pulley is less than a specified value, with the car speed less than a specified value, and as speed reduction ratio of the vehicle is larger than a specified value, the secondary pressure is set at a high pressure to set the speed changing speed where the drive belt generates slip to the primary pulley high.  When quick speed reduction is conducted to make the ultra-low car speed state, with quick reduction of the rotation speed of the primary pulley, generation of gross slip at the drive belt can thus be prevented.
