Filed: 1991-07-15
Abstract: PURPOSE:To surely reduce the speed of motor without fluctuation of braking by momentarily cancelling the braking operation and effecting the termination braking immediately after the motor speed is reduced from a high speed and reaches the desired process speed. CONSTITUTION:In a copying machine 1 providing a transfer drum 18 to conduct secondary supply of paper to the transfer drum 18 with a dedicated paper feed motor 30, a motor controller rotates at a high speed the dedicated motor 30 upon initiation of secondary paper supply and effectuates the braking operation surely to the process speed after a constant period of time.

Title: Method and device for steering hydrofoil craft
Inventor: IMAMURA HIROSHI
IPC: B63H25/46
Filed: 1989-07-05
Abstract: PURPOSE:To make it possible to turn a craft at a low craft speed by applying a sufficient rotation force to a craft body by driving a foward strat and changing the jet direction of jet water from a propulsion pump in steering at a low speed. CONSTITUTION:A forward strat 3 provided at a bow 2 is driven for steering at a high craft speed to make it possible to obtain a sufficient rotation force. At the time of a low speed, the craft is steered by driving this forward strat 3, while the jet direction of jet water from a propulsion pump for obtaining a propulsion force is changed by a deflector. A small rotation force applied to a craft body 1 obtained by the forward strat 3 at the time of a low speed can thus be compensated by jet water which collides with the deflector to convert the direction, thereby a sufficient rotation force can be applied to the craft body 1 to achieve turning.
