Title: Piezoelectric transducer and its production
Inventor: TAKEUCHI YASUTO
IPC: G01N29/04
Filed: 1982-03-12
Abstract: PURPOSE:To produce satisfactorily a single pulse having spectrum of a wide band, by reducing gradually the intensity of polarization toward the shortest direction between plural driving electrodes on a single face of a plate type piezoelectric material and a counter electrode on the other side of said piezoelectric material. CONSTITUTION:Driving electrodes 2a-2n are provided to a piezoelectric plate 1, and lead wires 3a-3n are connected to those driving electrodes respectively. A counter electrode 4 is coated on the entire surface of the other side of the plate 1 and grounded via a lead wire. The intensity of polarization of a piezoelectric electrode 1 set right under the electrodes 2a-2n is gradually reduced toward the electrode 4 as shown by a curve (a). At the same time the direction of polarization is set vertical to produce polarities opposite to each other with each group of adjacent electrodes. As a result, no point of sensitivity 0 exists for the frequency characteristics. This enables an impulse response of a wide range of spectrum.

Filed: 1981-03-18
Abstract: PURPOSE:To raise the efficiency of operation as well as save heat energy required by using a manufacturing method for a highly tough steel plate, consisting of a blooming process in which a given dimension of cast strip is heated and rolled and a hot-rolling process in which the cast strip is heated and rolled one time. CONSTITUTION:Cast steel strips of 3,200cm<2> or more are heated to 1,200 deg.C or higher and then bloomed and rolled to an intermediate thickness 2-5 times as much as final product. Then, the cast steel strip is cooled to 650 deg.C or lower, reheated to 800-950 deg.C in a hot roll mill, and then hot-rolled at a total draft of 30% or more and at a finish temperature of 690-740 deg.C. Thus, since one-time hot rolling is saved from the conventional hot rolling processes, the operating efficiency can be raised and heat energy to be consumed can also be saved.

Abstract: PURPOSE:To attain the reception during transmission and to prevent howling completely by using an output of a differential amplifier applying positive feedback of a received output with a gain of nearly '1', taking its synthesized signal as one input and taking only the reception output as the other input as a transmission output. CONSTITUTION:If other party is busy, a reception signal passes through a talking circuit network CL, amplified by an amplifier A1, and drives a microphone in common use for speaker MS via an amplifier A2 whose gain is the unity. The reception output is inputted also to an input terminal (b) of the differential amplifier DA at the same time and since its signal is the same as the output of the amplifier A1 inputted to an input terminal (a) of the amplifier DA, the output of the amplifier DA is zero. If its own station starts talking while the opposite party is busy, although the synthesis signal between the transmission input and the reception output is inputted to the terminal (b), since only the received output is cancelled by a signal from the terminal (a), only the transmission input is amplified and outputted at the output terminal (c) of the amplifier DA and it is sent to a line L via the circuit network CL.
