Title: Gated transmission circuit
Inventor: AUSTIN KENNETH
IPC: H03K19/177
Filed: 1986-09-10
Granted: 1995-03-07
Abstract: A gated binary signal transmission circuit in a field effect semiconductor chip comprises a single signal-pass transistor (20A, B) connected between a bit signal input (28A, B) to one of its electrodes (24A, B) and a bit signal output (12A, B) from another of its electrodes (26A, B). Its control electrode (22A, B) is connected for temporary energisations by switching circuitry (32,34) operative only at prescribed intervals, the single signal-pass transistor (20A, B) being operative to pass signals between such energisations of its control electrode (22A, B). Conduction of the single signal-pass transistor between energisations will persist, though with some decay, due to inherent capacitance and the control electrode being left "floating" between energisations.

The control section determines whether or not the magnitude of the peak value is nearly equal to a predetermined value. If the result is negative the control section refers to a gain data table to determine a change amount of the gain data, and supplies the updated data to the data pulse generator.

Abstract: A polyurethane (I) of 1000 to 100000 in molecular weight, comprising plural segments, which are each structural units of A-B, A-C and A-D of the formulae:   A-B: - @NH-R<1>-NH-@-aza-   A-C: - @NH-R<1>-NH-@-Z-R<2>-Z- and   A-D: - @NH-R<1>-NH@-O-R<3>-O- the molar proportion of the said segments of A-B, A-C and A-D i.e. x : y : z being 0.01 to 0.8 : 0 to 0.80 : 0 to 0.99, provided that the sum of x, y and z is 1.0;  wherein R<1> is a skeleton of a diisocyanate,  aza is a group of the formula: <CHEM> wherein Y<1> and Y<2>, represent oxygen, imino (-NH-) and hydrocarbon derivatives thereof;  R<4> and R<5> are optional substituents;  R<2> is a polyalkylene glycol residue;  Z is oxygen or imino; R<3> is alkylene or the residue of an ether or secondary or tertiary amine. The polurethanes are useful for coating medicaments for release in the large intestine.

Title: Process of cigarette filter using silica gel
Inventor: YU KWANG-KUN
IPC: A24D3/06
Filed: 1990-07-07
Granted: 1992-08-24
Abstract: The cigarette filter is produced by (A) heating silica gel to 200-500 deg.C, which has pore  diameter  of  50-100  angstrom  and specific surface area of 300-700 m2/g, (B) spraying  0.2-0.8  wt.% polyethyleneglycol  (or  glycerine)  onto  heated  silica  gel  as water-retaining agent, while agitating silica gel, and (C) filling in treated silica gel between two acetate  filters  of  prescribed size. The produced  cigarette  filters  of  prescribed  size.  The produced  cigarette  filter  shows  excellent   adsorptivity   for hazardous components  such  as  hydrogen  cyanide,  formaldehyde, acetaldehyde or acrolein.
