Title: Driving equipment of vibrator motor
Inventor: KAWAI TORU
IPC: B06B1/06
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To make possible efficient control by controlling the driving of a motor by changing the frequency when a frequency signal is within a specified range and controlling the motor by PWM control when the frequency of the frequency signal reaches a threshold value. SOLUTION: This driving equipment has a PWM circuit 3 which modulates the pulse width of an oscillation signal from an oscillator circuit 2 based on the instruction from a control circuit 1. When an instruction to start a motor is issued, a starting duty is set in the PWM circuit 3 and a starting frequency is set in the oscillation circuit 2. Then, it is judged whether the driving frequency is higher than a specified value. When the driving frequency is judged higher than the specified value, a speed detected by a position and speed detecting circuit and a predetermined speed are compared. When the detected speed is lower than the set one, the operation to lower the frequency is repeated, and when the frequency becomes higher than the resonance frequency, the frequency is fixed there.  The duty is increased by a specified quantity and it is judged whether a rotating speed has reached a set value. When the rotating speed reaches the set value, the duty is decreased by the specified quantity. By this method, the efficient control can be done.

Title: Detection of corrosion of container wall
Inventor: BURAIAN AARU SUPAIZU
IPC: G01N17/00
Filed: 1988-12-02
Abstract: PURPOSE: To inspect the corrosion of a conductor indirectly by inducing current into the conductor and then analyzing the attenuation of the current. CONSTITUTION: The energy supply is interrupted rapidly by a transmitter 29 by attenuating pulses to an intensity 0 level rapidly in a transmission coil, thus inducing an eddy current in a covering 19 and in the inside of a pipe wall 15 and diffusing the eddy current toward the inside of each conductor in a direction away from an antenna 27 and attenuating it. Also, a reception coil detects the presence and attenuation of the induced eddy current in the conductor. Then, a receiver 31 samples a signal detected by the reception coil and sends it to a digital computer 33.  At this time, the attenuation of induction current at the part of the container wall 15 is recorded over a certain amount of time and the record is interpreted to determine the thickness of the part of the container wall 15, thus inferring whether the part of the container wall 15 is corroded or not from the determined thickness.
