Title: Power steering apparatus
Inventor: KONISHI HIDEO
IPC: B62D5/22
Filed: 1982-08-23
Abstract: PURPOSE:To make the entire device small-sized by providing a C-shaped spring between an input shaft gearing with a handle shaft and an output shaft whereon a pinion is formed, by controlling a spool valve by this spring, and by giving a pre-load thereby between the input and output shafts. CONSTITUTION:A gear 13 rotating with an input shaft 1 engages with a gear 31, and is provided with a pin 15. A gear 14 is provided on an output shaft 4 whereon a pinion is formed. The gear 14 is engaged with a gear 32 and provided with a pin 16. The pins 15 and 16 are engaged with a C-shaped spring 17 at the cut part thereof. The rotation of the input shaft 1 is transmitted to the output shaft 4 by the spring 17 and the pins 15 and 16, while the relative rotation of the two shafts caused by the bending of the spring is transmitted to the gears 31 and 32. Since Oldham's couplings 33-35 are provided between these two gears, the gear 31 is moved in the direction of the front and back of this sheet, and this motion is transmitted to a spool valve by a rod 19. Since the C-shaped spring is used, a pre-load is given between the input and output shafts.

Title: Motor driving circuit
Inventor: SHIMAZAKI TSUTOMU
IPC: H02P6/12
Filed: 1994-06-28
Abstract: PURPOSE:To maintain the drive power voltage of an output transistor at proper value. CONSTITUTION:The first saturation preventive circuit 40 detects the lower envelope voltage of the voltage ripple (motor output voltage) of output ends OUT1-3, and detects saturation degree by this being close to earth voltage, and outputs a signal regarding this saturation degree. A PWM comparator 42 compares the signal of saturation degree with triangular waves, and outputs a signal with pulse width depending on the saturation degree, and a VM generating circuit decides the drive power voltage VM of transistors Q1-Q6 from this pulse signal. Moreover, a middle point control circuit 50 sets the middle point of motor output voltage to the middle point of drive power voltage VM. Hereby, the saturation in the output transistors Q1-Q6 can be prevented by lowering the drive power voltage VM as far as possible. Furthermore, when the output voltage of the motor goes high abnormally, the second saturation preventive circuit 52 lessens the torque value. Hereby, the saturation of the output transistor can be prevented by suppressing the rise of motor output voltage.
