Patent EP-0160988-A2 (EP)
Inventor: KARGER BARRY L
IPC: B01J20/32
Filed: 1985-05-09
Abstract: Fast high resolution separations of biopolymers with retention of biological activity have been achieved by hydrophobic interaction chromatography using trialkoxy silyl ethers of the general formula (RO) 3 Si - (CH 2 ) m - 0 - (CH 2  CH 2 O) n - (CH 2 ) p R chemically bonded to silica-based chromatographic supports, In the formula R is alkyl of from one to five carbons, m is an integer from two to five, n is an integer from one to five, p is an integer from zero of ten. and R is methyl, phenyl, or substituted phenyl. Stable and reproducible bonded phases are prepared in a novel solventless procedure by a bonding process which uses a defined and controlled amount of water on the silica surface and a gaseous or volatile basic catalyst such as ammonia to produce a controlled amount of silane polymerization and cross-linking in addition to extensive bonding between silane and silica. High performance liquid chromatography on such weakly hydrophobic stationary phases using aqueous eluents and decreasing salt gradients under mild conditions permits high speed, high resolution separations of biopolymers such as proteins without destruction of their biological activity and without column degradation. Size exclusion chromatography can also be performed on these phases using low ionic strength eluents.

Abstract: Miscorrection of triple errors is avoided in a memory system equipped with a single bit error detection and cor- rection/double bit error detection code by providing a double bit error logging technique. The address of each fetched word is logged in which a double bit error is detected. The address of each fetched word in which a single bit error is detected is compared with all logged addresses. If a coincidence is found between the compared addresses, a triple bit error alerting signal is generated and error recovery procedures are initiated.

Abstract: The present invention relates to a logic circuit which reduces occurrence of breakdown of a pull-down transistor (T 3 ) and a pull-up transistor (T 4 ; T a ) in the output stage when a high voltage is applied to the power supply line and ensures high voltage resistance. The logic circuit of the present invention controls the pull-up transistor (T 4 ; T,) provided between a first power supply (V cc ) and an output terminal (OUT) for ON and OFF with a collector voltage of a phase splitter transistor (T 2 ) and controls the pull-down transistor (T 3 ) provided between the second power supply (GND) and the output terminal (OUT) with an emitter voltage. Breakdown of said pull-down and pull-up transistors (T 3 ; T 4 ; T.) can be reduced and a high voltage resistance is ensured by providing a protection circuit (P) which discharges the base of pull-down transistor (T 3 ) and turns OFF said pull-down transistor (T 3 ) by detecting a voltage difference between the first power supply (V cc ) and the second power supply (GND) when it exceeds the specified value.

Title: IC socket contact
Inventor: NONAKA YOSHIMASA
IPC: H05K7/10
Filed: 1985-02-08
Abstract: A specialized contact structure is provided for IC sockets to permit increased contact pressure and to permit contact with an IC lead at its base instead of at its tip. The socket includes a substrate with the subject contacts embedded therein in rows, an overlying lever-actuated plate having corresponding rows of apertures, with the apertures corresponding to IC lead positions. In operation, the IC leads are inserted into the apertures in the lever-actuated plate and the plate with the inserted leads is moved laterally, such that the leads are moved laterally into contact with the mating contact arms of the contacts mounted in the substrate. In order to provide reliable contact with the base of the lead, each contact has a leg portion extending outwardly from the substrate, with the contact being formed from contact arms in the form of a pair of opposing rectangular tongue pieces integrally formed with the leg portion, and abutment portions formed by inwardly bending the tips of the tongue pieces by an angle more than 90 degrees so that the tips of the contact arms come into contact with each other to form a spring-loaded contact adjacent the top of the tongue pieces. The sides of the spring-loaded contact into which an IC lead is to be laterally moved has a "V"-shaped face to guide the IC lead in between the contact arms, with a laterally-running top edge bevel being provided on each of the mating inwardly-bent contact arms.

Abstract: @ A CCD output signal reproduction apparatus is applied to a solid state image sensor (10) that performs a swing-driven image pickup operation. This image sensor (10) is synchronized with one frame period and swings periodically and relatively in relation to incident light to pickup the image while changing the sampling positions in the A and B field periods. The carrier generator (58) produces first and second sinusoidal carrier signals (56) which have the same frequency as that of the read out frequency of the image sensor (10). An amplitude modulator (54) modulates the carrier signals in response to the waveforms of the image signals supplied from the image sensor (10). Accordingly, amplitude-modulated A, B field image signals, which are phase-shifted by half the pixel pitch of the pixel arrangement of the image sensor (10). A carrier clamp circuit (60) forcibly clamps the different peak potentials of the carrier waveforms of the amplitude-modulated field image signals to the reference potential level. In this way, when the field image signal whose waveform has been shaped is synthesized on the reproduction screen, it is possible to obtain a one frame image which has a resolution twice that determined by the actual number of pixels.

Abstract: Fluoropolymer containing films (10-11) are separately formed and applied to substrates (12) to form novel composites. The invention process comprises the steps of: (1) separately forming a uniform film comprising a metered layer of a fluoropolymer containing material; (2) treating the substrate to facilitate film adhesion and bonding; (3) uniformly contacting at least one face of the film with a treated surface of the substrate; and (4) transferring the film material to the treated substrate with heat and pressure to obtain a smooth, uniform coated composite. By a decalcomania technique, the film may be cast in a single or multiple layers on a support member, such as a metal foil, drum or belt, and thereafter the face of the film opposite the support member is uniformly contacted with the substrate and transferred. The support member is thereafter removed or stripped from the film to expose the laminated composite surface. Alternatively, the film may be removed from the support member prior to contacting with the substrate.

Abstract: A top entry trunnion ball valve is provided having a valve body forming seat recesses (76, 781 with seat members (92. 94) movable disposed therein and urged towards sealing engagement with a spherical valve member (22) by spring members (126, 128) and by differential pressure induced force. A seat retractor mechanism is movably disposed within the valve body and is movable by an externally controlled tool into retracting engagement with the seat members (92. 94). The seat members and the seat retractor element have co-operative cam surfaces (162, 164, 166)that cause camming movement of the seat members away from the valve member upon linear movement of the seat retractor. Upper and lower portions of the seats may be subect to simultaneous camming activity. The valve member defines a face-to-face dimension smaller than the diameter of the spherical surface thereof and the seat retractor is capable of moving the seat members to a spaced relation slightly greater than the face-to-face dimension of the valve member. This permits the valve member to be removed when the seat members are retracted. A rotatable actuator stem member (50) supported by the bonnet (26) closure of the valve has interengaging driving relation with a trunnion member (46) of the valve element and is orientated so that the stem member (50) is not subjected to side thrust forces upon rotation of the valve member or in its closed position. A fire safe seal and spring chamber (124, 125) is in communication with a relief passage having volumetric closure plugs (150. 152) permitting introduction of solvent or other softening agent into the spring chambers for removal of any accumulation of foreign material therein.
