Title: Sound volume control system
Inventor: KIMU EI RABUJIYOI
IPC: H03F3/68
Filed: 1991-08-13
Abstract: PURPOSE: To automatically suite an instantaneous acoustic level and a total volume to a prescribed limit. CONSTITUTION: Microphones 38 and 39 sample acoustic outputs from speakers 20-23. The analog signals of obtained time areas are high speed Fourier transformed, and turned into the signal in a frequency area indicating the intensity of a frequency band. The intensity of each band is compared with the allowable level limit stored for each frequency level. Attenuators AF1-AF16 attenuate each synchronizing frequency band so that the outputs from the speakers can not include the frequency beyond the allowable limit. Weighted allowable averages for each frequency are integrated, and a signal indicating a cumulative acoustic volume is generated. When the total volume is beyond the allowable limit for a listening time, another attenuator is operated by the cumulative volume signal, and the sound volume from the speaker is decreased to an allowable level.

Filed: 1988-08-16
Abstract: PURPOSE:To accurately detect an exhaust flow rate by constituting a tubro molecular pump so that the output torque for a motor is kept constant in the manner of feeding back the detected load condition of a rotary blade. CONSTITUTION:In the case an induction motor is controlled so as to keep the V/F constant (where, V is a voltage impressed to the motor, F is a frequency to drive the motor), the motor is being operated with the set values V,F (point a) at the normal time, but when the load is changed, the torque to actuate the rotary blade is changed, thereby an operating point of the motor is conformed to a torque characteristic curve of the motor and the number of rotation is changed, if V and F are remained constant. In the case the exhaust speed can be kept constant by a pump which is connected to a discharge side of the turbo molecular pump, a balanced point (point c) for the load torque and the rotating torque of the motor is found by changing the number of rotation for the rotary blade with V/F remained constant, if a gas molecular flow rate is constant. That is, the values of V and F are set to optimum values by conforming with the load condition and remaining the value of V/F constant, and a slip of the motor is controlled to be constant, then the exhaust flow rate is detected by measuring V or F at this time.
