Title: Ultrasonic transmission circuit
Inventor: HYODO SHIGETOSHI
IPC: G01N29/22
Filed: 1993-06-01
Abstract: PURPOSE:To reduce consumed electric power in an ultrasonic transmission circuit which amplifies a transmission signal generated synchronously with a transmission synchronous signal through an amplifying element and outputs it to an ultrasonic piezoelectric transducer. CONSTITUTION:A transmission circuit 11 has a wideband power amplifier 12 which amplifies a transmission signal from a terminal 13 and outputs it from a terminal 16 to an ultrasonic piezoelectric transducer SU. The source voltage of the amplifier 12 is applied through a capacitor C when a switch SW is turned on. The switch SW is rept turned onduring a term from a fixed time before the front edge of a transmission synchronous signal to the rear edge of the said signal by a control signal which rises a fixed time before the front edge of the transmission synchronous signal and falls clown at the time of coinciding with the rear edge of the said signal. Thus, the wideband power amplifier 12 is actuated for only both a term when the transmission signal is input and a fixed time just before it, and separated from a power source terminal 15 except the above terms.

Title: Sound field variable device
Inventor: ISHIKAWA SEIICHI
IPC: H04S1/00
Filed: 1988-05-27
Abstract: PURPOSE:To attain sound field reproduction changing continuously in real time without generating noise by using two signal processing means and switching the signal outputted from the one signal processing means to the signal outputted from the other signal processing means smoothly. CONSTITUTION:After an output signal of a 2nd signal processing means whose processing procedure is changed is made stable in a state without any noise, a system control means 4 gives a switching command to a signal switching means 3. The signal switching means 3 reduces a signal outputted from a 1st signal processing means 1 gradually and increases gradually the signal outputted from the 2nd signal processing means 2 representing the next sound field and adds both the signals and only the output of the 2nd signal processing means 2 representing the last sound field is outputted thereby switching the signal smoothly in this way. The operation above is applied alternately to the 1st and 2nd signal processing means 1, 2 every time the sound field is changed. Thus, the sound field is changed continuously without switching noise in real time.

IPC: C07C51/42
Filed: 1979-10-12
Abstract: PURPOSE: To suppress the formation of by-products, and to obtain the titled acid useful as a raw material for fluorescent dye, etc. in high purity, by oxidizing o- xylene with a molecular oxygen-containing gas in liquid phase, treating the reaction product under specific conditions to give an oily layer, followed by the recycling the oily layer for the above-mentioned oxidation.

In the case of a low conversion 20W40%, since amounts of o-phthalic acid and phthalide as by-products are relatively small, o- xylene is added to the product solution of oxidation, which is recrystallized and filtered to give the desired o-toluic acid as a cake. To the prepared filtrate is added water or a basic aqueous solution so that it is separated into an oily layer and an aqueous layer, and the by-products, e.g., o-phthalic acid, etc. are transferred into the aqueous layer side and removed, and the oily layer is recycled through the oxidative process.

IPC: E01D1/00
Filed: 1985-06-17
Abstract: PURPOSE:To effectively suppress vibration of an oscillator, by selecting a component of relatively low frequency of the vibrative speed of the oscillator and applying control force in accordance with said frequency component to the oscillator by an actuator. CONSTITUTION:A vibrative speed of an oscillator 4 is obtained by detecting a signal in an accelerometer 5 to be integrated by an integrator 7. Of the obtained vibrative speed, only a component of frequency lower than a predetermined frequency is selected by a low-pass filter 11, and a controller gives in control force, in proportion to the selected signal, a vibration of reverse phase to the oscillator 4 by an actuator 3. The controller, preventing a component of high frequency in the vibrative speed from participating in a control of the actuator, eliminates a condition of vibration that it can not be prevented by saturating the actuator with control force.
