Abstract: Purification and solubilization of a protein produced in a transformant microorganism as insoluble, biologically inactive inclusion bodies can be effected by extracting the inclusion bodies into a buffered solution of sodium dodecyl sulfate (SDS) to solubilize the protein; treating the SDS-protein solution with urea; removing the SDS and purifying the protein by chromatography on an anion-exchange column; and dialyzing the solution obtained from the anion-exchange column to remove urea, thereby allowing the protein to fold into its native conformation. The solution thus obtained can be activated by removing soluble protein aggregates by, for examble, ultrafiltration or chromatography on a weak anion-exchange column.

Granted: 1992-04-29
Abstract: The system uses a 3B2T line code, i.e. one in which sets of three or triplets of binary digits are converted into pairs or duplets of ternary elements. All nine of the possible ternary duplets are used, in such a way that the same ternary duplet does not occur twice consecutively. This is done in one version by using the ninth duplet 00 as a repeat indicator, and in the other version by a conversion process in which each conversion operation takes into account the result of the preceding operation.

Abstract: Hot-dipped steel plate produced by dipping steel in a plating bath of zinc-base or zinc-aluminum-base alloy, and a process for its production. Hot-dipped steel plate has on its surface a film of cobalt oxide, iron oxide or both of them, and this oxide film serves to prevent the plate from discoloring to grayish black when said plate is one treated to minimize spangles, or it has a plating layer which contains a corrosion resistance-improving element such as magnesium or aluminum, or otherwise it is one chromated after machining. The oxide film is formed on the surface of the hot-dipped steel plate by spraying an aqueous solution containing a cobalt or iron salt or both of them against the surface of the plating layer having a temperature of 170oC or above to thereby thermally decompose the salt. Preferred salts include nitrates and chlorides of cobalt and iron.

Granted: 1991-09-04
Abstract: A vertical deflection amplifier (20) of a video display apparatus includes first (Q1) and second (Q2) transistor amplifier output stages arranged in a totem-pole, push-pull configuration. A vertical-deflection winding (LV) is coupled to the output stages at a deflection amplifier output terminal (22). An S-capacitor (C1) is coupled to the deflection winding (LV) at a second terminal (21) remote from the output terminal (22). A source (23) of deflection rate signals is coupled to the deflection amplifier (20) for generating a deflection current (iv) in the deflection winding (LV). A base current generating circuit (40) is coupled to one (Q1) of the transistor amplifier output stages for providing base current (i1) thereto. The S-capacitor voltage (V1) is applied to the base current generating circuit (40) for enabling conduction of base current (i1) in the one amplifier output stage (Q1). When the video display apparatus is first turned on, the initially discharged S-capacitor (C1) is slowly charged from a DC voltage supply (+30V) to delay generation of vertical def lection past completion of picture tube degaussing. A DC power supply (16) upon energization in response to a switch (15) produces a DC level (+DC2) sufficient for operating the deflection amplifier prior to the conclusion of degaussing.
