Title: Method of filling vessel with liquid and heat-sealing liquid and device and vessel executing said method
Inventor: GERUHARUTO HANZEN
IPC: B65B3/02
Filed: 1988-06-10
Abstract: PURPOSE: To minimize a residual air in a container by raising a filling liquid face by elastic deformation during first and second heat sealing operations to the liquid filling section of the container. CONSTITUTION: The side wall of bag-like container 1 is recessed by scavenging mechanism 5 so that liquid level 12 in the container can rise up inside a liquid filling section 3. In the process of raising the liquid level to line 13, most of the air existing in the bag-like container 1 and liquid filling section 3 is exhausted outside through an end tip 14. While the distance between the liquid level and the heat sealing position is still sufficiently large during the heat sealing operation of the end tip 14 by an optional head 10, the residual air in the liquid filling section 3 is as small as to be reflected because the section of a through hole of the liquid filling section 3 is minimized by the first heat sealing operation. During heat sealing of the end tip 14, the top of the tube is cut off by an optional head 10.  In the second heat sealing operation, the scavenging mechanism 5 is retracted again to eliminate again the recession of the side wall of the bag-like container 1 to recover the original shape of the container body.

Title: Probability gradient of hybrid for convergence of suitable filter
Inventor: ROI JII BATORUUNI
IPC: H03H17/02
Filed: 1989-06-09
Abstract: PURPOSE: To update a coefficient responding to adaptive filter impulse by using a code algorithm error signal so as to update the coefficient when a least means squares error signal is smaller than a value selected in advance. CONSTITUTION: When a prediction error e(n) is large at first, a hybrid stochastic gradient(HSG) acts like a least mean squares(LMS) algorithm having a high speed convergence characteristic. In the case that there is any channel that is not converted by the LMS as to a prescribed positive coefficient adaptive step, the HSG acts like a symbolic algorithm(SA), which has a slow but warranted convergence. When the convergence is progressed and a prediction error e(n) gets smaller, the HSG is switched automatically into the SA format and updated coefficient are still observed. In the steady-state, the HSG is operated as the SA and then it minimizes the predicted value for the absolute value of the error.

Title: Ultrasonic transducer
Inventor: TODA KOUJI
IPC: G01S7/521
Filed: 1977-12-06
Abstract: PURPOSE:To realize an ultrasonic transducer with blind-shaped electrodes which focuses ultrasonic beams on one point by fixing intervals of electrodes and the phase difference of an applied signal under fixed conditions respectively. CONSTITUTION:On the surface of a piezoelectric substance, blind-shaped electrodes 4a to 4i are arranged in the longish direction of electrode fingers. Here, connecting every other blind-shaped electrode constitutes a single-phase electrode and connecting every third electrode, on the other hand, constitutes a three-phase electrode. Then, ultrasonic beams can be focused in one direction (X direction) by setting the electrode intervals under fixed conditions. Next, ultrasonic beams can be focused in the Y-axial direction by applying signals, which are equal in frequency and out of phase by (phi1...) statisfying the fixed conditions, to electrodes 4a to 4i. They can therefore be focused on point F through combinational focusing in the X-axial and Y-axial directions.

Title: Tubeless throwing pressure-type liquid level gage
Inventor: NAGURA YUKITOSHI
IPC: G01F23/18
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To measure a liquid level precisely without being affected by atmospheric pressure, by a method wherein a pressure sensing part which senses a liquid pressure and a pressure sensing part which senses only atmospheric pressure are installed separately, and electric signals of both sensing parts are computed. SOLUTION: A pressure which is applied to a liquid-pressure sensing part 1 is a pressure in which a head pressure and atmospheric pressure are added. A pressure which is applied to an atmospheric-pressure sensing part 2 in only atmospheric pressure. From both pressure sensing parts, electric signals according to their pressures are sent to an electric-signal computing device 3 by a signal cable. When the value of the latter is subtracted from that of the former, a head pressure can be computed by the electric-signal computing device 3. In addition, when the head pressure is divided by the density of a liquid, a liquid level can be computed. By making use of this action, the liquid level can be measured without being affected by atmospheric pressure even when an air tube is not installed between the liquid-pressure sensing part 1 and the air.  In addition, since an air tube is not contained in the signal cable from the liquid-pressure sensing part 1, the signal cable can be manufactured easily, and it can be executed easily when a liquid level gage is installed.
