Title: Method and device for iron loss value evaluation
Inventor: NAKAMURA MASAHIRO
IPC: G01N29/00
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To enable an iron loss value of a steel plate to be calculated and evaluated by receiving a plate wave ultrasonic wave by plural receivers with their different distances with transmitters and obtaining a sound speed with high precision from a distance between delay time between the receivers obtained from the receive signal and a distance between the receivers. SOLUTION: An ultrasonic pulser 11 pulse-drives a transmitter T according to a transmission trigger signal of a system controller 10 and sends a plate wave ultrasonic wave. An A/D converter 13 samples receive signals of the receivers R1 and R2 with a send trigger signal being a reference thereof and performs mutual correlative calculation using these. A system controller 10 calculates a sound speed of the plate wave ultrasonic wave with high precision when the maximum value of the mutual correlative calculation value is a transmission delay time. The system controller 10 obtains an iron loss value of an electromagnetic steel plate from the sound speed based on the relationship between the sound speed obtained in advance and the iron loss value of the electromagnetic steel plate.  Thus, wave change having measurement dynamic range and including noise hardly affects it, and online continuous measurement is made possible.

Title: Pulse width modulating amplifier
Inventor: SATOU HIDEO
IPC: H03F3/217
Filed: 1981-11-24
Abstract: PURPOSE:To obtain a pulse width modulating amplifier with a good distortion factor, by modulating the pulse width of input signals and applying the amplitude modulation using the input signal. CONSTITUTION:A sound signal inputted to a terminal 10 is amplified by amplifiers 1, 2. A clipper 3 clips the sound signal at a prescribed level before a power amplifier becomes nonconductive (zero output). A clipped output is modulated for the pulse width at a comparator 5. Signals of the same pulse width are arranged for the clipped part. This pulse modulated wave is amplified at a pulse amplifier 6 and enters the clipper 7. The clipper 7 clips the pulse width modulating wave by taking an audio signal from the audio amplifier 2 as a bias voltage. The part clipped to this audio signal has a constant pulse width and the amplitude is proportional to the audio signal. This signal is amplified for pulse power. Thus, an output signal without distortion in the demodulated waveform can be obtained.

Abstract: PURPOSE: To increase the fuel to be supplied during acceleration, by providing additional fuel control device which imparts fuel pressure by means of a diaphragm mechanism responding to change of intake regative pressure and discharges fuel through a channel other than normal fuel passages.  
     CONSTITUTION: When a throttle valve 3 is abruptly opened to be accelerated, the intake negative pressure in the downstream of the throttle valve 3 should rapidly approach an atomspheric pressure. In this time, a pressure which is applied to an air chamber 31 having a suction communication passage 28 quickly approaches the atomspheric pressure, causing a diaphragm 22 to move rightward, so that a fuel chamber 30 is increased in pressure. And then, when this pressure increases to overcome that of a spring 24 of the check valve 23, the valve 23 is opened and fuel is discharged from a pump nozzle 26.
