Porous, cross-linked polymeric materials comprising hydrocarbon residues can be sulphonated to produce sulphonated polymers which are able to absorb large volumes of ionic solutions and also act as ion-exchange resins.

In a brake actuator device having a fluid pressure actuated service brake and a spring-applied, fluid pressure released auxiliary brake that cooperates with the service brake via a friction clutch mechanism, there is provided a manual release mechanism for releasing the spring-applied brake in the absence of fluid pressure. The manual release mechanism operates to relieve the tension of the actuat...

PURPOSE:To enlarge the contact space between the mounting plane of substrate and solder in case of actual mounting assuring direct mounting on the substrate without forming a hole at all by a method wherein the actual mounting space is enlarged by means of bending the ends of pins for mounting the substrate. CONSTITUTION:A pellet 3 is mounted on the central surface of substrate 2 made of alumina u...

PURPOSE:To make it possible to generate a magnetic field having a highly uniform degree, by arranging a correction coil at a position, where the high uniformity of a magnetic field can be realized, with respect to the field coil of a medical nuclear magnetic resonance tomographic apparatus. CONSTITUTION:(a) is the inner radius of a field coil 1 and two-dimensional coordinates of each point are dis...

PURPOSE:To prevent the copper powder from oxidation, by covering the surface of the copper powder used for an electroconductive paste with a solution containing a silane coupling agent and curing. CONSTITUTION:The copper powder for electroconductive paste used for forming an electrode, electroconductive circuit pattern on a ceramic substrate is immersed in a solution in which a silane coupling age...

PURPOSE:To suppress increase in number of terminal to the minimum so that only necessary circuits can be tested, by performing scan-in and scan-out to an optional state storing circuit group. CONSTITUTION:In order to operate the scanning circuit shown in the figure as an ordinary scanning circuit, an enable signal T, scan-in signal line 2 which is set to an independent mode at '0', and scan-out si...

PURPOSE:To contrive to reduce the manufacturing man-hour of a semiconductor device by a method wherein the chip supporting part and the leads on both sides of the chip supporting part are all formed of a parent material consisting of an insulative plastics and a conductor layer, which is at least partially formed by coating on the surface of the parent material. CONSTITUTION:The inner end of the c...

C-20 modified derivatives of tylosin and tylosin-like macrolides useful as antibiotics and as intermediates to other antibiotics.

PURPOSE:To simplify a necessary redundancy circuit by storing a defective address signal and a defective bit address in said signal, as defective information, and switching only a data line which has become defective actually, to a redundancy data line. CONSTITUTION:Redundancy memory arrays YR-ARY1, YR-ARY2 are provided on memory arrays M-ARY1, M-ARY2, respectively, and the redundancy memory array...

PURPOSE:To produce the objective product in high yield, in the chemical dehydration reaction to produce a high-boiling compound having higher boiling point than an organic solvent, by carrying out the reaction while disilling out the produced water together with the organic solvent by the vapor-recompression process. CONSTITUTION:A reaction for producing a high-boiling compound having higher boili...

PURPOSE:To release abnormal operations of a CPU so as to prevent wrong outputs, by resetting the CPU to its initial state when the 1st data readout signal and 2nd data readout signal or write signal are simultaneously generated. CONSTITUTION:When the 1st data readout signal and 2nd data readout signal are simultaneously outputted due to abnormal operations of a CPU1, a transistor 24 is set to an i...

Compounds of formula (I) and (III) wherein R is phenyl; R<1> is phenyl or -AP(AuX) (R)2; A is the same and is a straight or branched alkanediyl chain of from one to six carbon atoms; n is 0 or 1; m is the same and is 0 or 1; and X is the same and is halo or thiosugar; provided that when n is 1, R<1> is phenyl; compositions containing them and their use in therapy for inhibiting the growth o...

PURPOSE:To prevent blind striking of dots from occurring and print straight lines, broken lines or the like at high speed, by forming a video signal from the product of a staircase with a step amount of 0 and a digital value indicative of the use or non-use of each dot. CONSTITUTION:Two kinds of staircases are programmed in a staircase RAM36. A staircase SAW0 is used for printing 7 dots vertically...
