Title: Hinge structure
Inventor: FUKUO MICHIHIRO
IPC: F16C11/10
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To provide a hinge structure which is not broken even when excessive force is applied on it and capable of stopping a revolving member at a specified angle without increasing the number of parts. SOLUTION: A pressure surface 28 is formed on a shaft 20 installed on a transmitting part 14. A pin 36 is stored in a recessed groove 34 formed on an inner peripheral wall of a shaft hole axially supporting the shaft 20, and it is energized to a center of rotation of the shaft 20 by a coil spring 38. When the shaft 20 is rotated and the pressure surface 28 comes to a position of the pin 36, the pin 36 energized by the coil spring 38 enters a clearance 34 and pressurizes the pressure surface 28, and accordingly, the shaft 20 is rotated and the pin 36 is positioned at a center of the pressure surface 28 and stabilized. Even when the shaft 20 is rotated in either direction from this state, the pin 36 pressurizes the pressure surface 28 and the shaft 20 returns to an original state.  As the coil spring 38 is annular, even if there are a plural number of the pins 36, it is possible to energize them by the one coil spring 38.

Title: Electric vehicle motor control
Inventor: NAKAMURA SHINOBU
IPC: B60L7/00
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling a motor of an electric vehicle which allows a vehicle to stop smoothly on a down slope without giving shock and a sense of incompatibility to a driver. SOLUTION: As soon as an accelerator 12 turns OFF, a main CPU 14 reduces the PWM(pulse width modulation) output along a specified gradient and lowers a vehicle speed. When the PWM output becomes zero, the main CPU 14 judges whether the rotating speed of a motor 20 (a vehicle speed) is a specified value or above, based on pulses from an encoder A 22 and an encoder B 24. When the rotating speed is the specified value or above, the main CPU 14 supplies, to a motor driving circuit 16, negative PWM output which rotates the motor 20 in the opposite direction to the progressive direction of the vehicle, and suppresses acceleration of the vehicle on an down slope.  When the vehicle speed becomes lower than the specified speed and reaches a safety stopping speed, the main CPU 14 stops the negative PWM output and outputs a brake ON signal to a brake control circuit 26 to turn an electromagnetic brake 28 ON and stop the vehicle.
