Title: Bicmos ecl-to-cmos level translator and buffer
Inventor: WONG BAN P
IPC: H03K19/0175
Filed: 1993-05-28
Abstract: An ECL-to-CMOS level translator and BiCMOS buffer are described. The current supplied from the first input PMOS transistor (P1) is the input current to a current mirror comprising the first and second NMOS transistors (N1 and N2). The cur-rent mirror controls the current sourcing and sinking capability of the translator. Third and fourth NMOS transistors (N3 and N4) are coupled to the first and second NMOS transistors in the current mirror and function to vary the source-to-body voltage of the first and second NMOS transistors and consequently their gain which results in increased current drive and sinking capa-bility. The BiCMOS differential buffer of the present invention provides a differential output signal on first and second output nodes (115 and 215). It is comprised of first and second cross-coupled buffers (100B and 200B). Cross-coupling the buffers re-sults in improved high-to-low transition times.

Title: Air pumping and ventilating device for a shoe
Inventor: TSE STEVEN
IPC: A43B7/06
Filed: 1995-03-09
Abstract: A shoe is provided with an air pumping device capable of supplying fresh air from the ambient atmosphere into the interior of the shoe. The air pumping device is detachable from the shoe so that it can be cleaned to remove dirts or alien objects that may block the air flow path. The air pumping device is located beneath the forepart of a foot wearing the shoe. When the user makes a step forward, an air bag (30) is compressed at the instant the forepart of the foot is bent to lift the heel off the grount, thereby generating an air pumping action. when the forepart of the foot stretches straight again, the air bag (30) restores to its original shape, thereby generating an air sucking action. As the user keeps moving, the air pumping device will pump air successively from the ambient atmosphere into the interior of the shoe. The air flow direction may be reversed so as to pump air inside the shoe out to the ambinet atmosphere.

Title: A noise-controlled communication apparatus
Inventor: SHIONO TAKASHI
IPC: H04B3/04
Filed: 1995-03-28
Abstract: A noise-controlled communication apparatus reduces an annoying effect to the other speaker due to an ambient noise on the transmitting side and improves articulation of the receiving voice under noise.  In a noise-controlled communication apparatus, a transmitting level detector detects a transmitting level above a threshold.          Then, a mode controller enters to a transmitting mode.          When the mode controller enters to the transmitting mode, a control mode switching circuit reduces attenuation of a transmitting signal.  When the noise-controlled communication apparatus detects a receiving signal, the mode controller enters to a receiving mode for passing through the receiving signal.  When the transmitting signal and receiving signal are not detected, the mode controller enters to an idle mode for attenuating the transmitting signal and receiving signal to half.

Title: Purification of alpha-1 proteinase inhibitor using novel chromatographic separation conditions
Inventor: LEBING WYTOLD R
IPC: A61K38/55
Filed: 1995-08-14
Abstract: Cation chromatography with solutions at pH less than 6.0 and low ionic strength can be utilized to purify human .alpha.-1 proteinase inhibitor (.alpha.-1 PI)  from biological fluids including plasma and plasma fractions.  The cation chromatography takes advantage of the fact that active .alpha.-1 PI does not bind to the cation column under these conditions but other proteins, including denatured .alpha.-1 PI and albumin, do.  The effect is that active .alpha.-1 PI flows through the chromatography column leaving the contaminating proteins behind.          Recovery of .alpha.-1 PI is high and improvement of purity is dramatic.
