Patent EP-0384680-A2 (EP)
Inventor: KELLEHER JOHN J JR
IPC: H02M1/15
Filed: 1990-02-19
Abstract: An input voltage source (V s ) supplies a DC voltage to a transformer (T) having a pair of inductively coupled primary windings (L₁, L₂). A controller (14) electrically couples the DC voltage across a first one of the pair of windings (L₁, L₂) during a first portion of a cycle to induce a voltage in a second one of the pair of windings (L₁, L₂) during such first portion of the cycle and electrically couples the DC voltage across the second one of the pair of windings (L₁, L₂) during a second, subsequent portion of the cycle to induce the voltage in the first one of the pair of windings (L₁, L₂) during the second portion of the cycle. A pair of diodes (D₁, D₂) couples the ends (A, B) of the primary windings (L₁, L₂) to a circuit (15′) including a controller (50) responsive to a level of the voltages induced in the pair of windings (L₁, L₂) exceeding a predetermined voltage, and a capacitor (C₂) and an inductor (L) for storing energy related to the excessive voltages. The controller (50) controls a switch (38) so as to direct the stored energy back to the voltage source (V s ) through a connection (42) from the inductor (L).

Abstract: A polyurethane covered golf ball is made by allowing the polyurethane cover stock material to partially cure in an open mold (10) and subsequently molding a golf ball product. The molding is done by first molding a smooth-surfaced golf ball product (32) in a smooth-walled fixed-pin mold (10) and then, in a second molding step, using a compression mold (50) to impart dimples onto the smooth-surfaced golf ball product. Between the two molding steps an intermediate curing step is employed. The initial curing time in an open mold and the intermediate curing time between the two molding steps is minimized through the use of a sufficient amount of catalyst, by keeping the smooth mold at an elevated temperature, or by using the fast-reacting chemical components.

Abstract: A nucleic acid sequence specific for genomic nucleic acid of  Mycobacterium tuberculosis  is disclosed. This sequence is from  M .  tuberculosis  and can hybridize with certain members of the tuberculosis complex of myco­bacteria, e.g.  M .  tuberculosis ,  M .  bovis  and the Montreal strain of  M .  bovis  (Calmette Bacille-Guerin). This invention also pertains to DNA fragments identified by amplification of mycobacterial nucleic acid by the polymerase chain reaction (PCR) technique using oligode­oxyribonucleotide primers derived from this isolated nucleic acid sequence of  M .  tuberculosis . DNA fragments amplified in this manner will specifically hybridize with nucleic acid from  M .  tuberculosis . 
     The invention also pertains to diagnostic methods such as hybridization assays which employ the nucleic acid sequences and to kits for performing the assays.

Abstract: A video data processing apparatus converts one of NTSC type and VGA type video signals to the other or overlays the two types of video signals and outputs them as either an NTSC type overlaid video signal or a VGA type overlaid video signal. The processing apparatus has two video memories (156, 174) for storing video signal data. One of the two video memories stores solely VGA type video data. The other video memory stores either VGA type video data or NTSC type video data depending upon the particular function being carried out by the processing apparatus. Video data may be read out from the other video memory using different scan rates so that an individually dedicated memory is not required for each type of video data in performing the above-mentinoed conversions and overlays.

Abstract: In a wire-cut EDM apparatus for cutting a workpiece (2) submerged in a processing tank (3) filled with a machining fluid (15), an opening (24) is made in the side wall of the tank through which an arm unit passes. A slide plate (14) also has an opening for passage of the arm unit and also prevents leakage from the space between the opening 24 and the arm unit. In one preferred embodiment a fluid flow between the slide plate and arm unit is used to prevent fluid in the tank from escaping through the space between the slide plate (14) and the arm unit. Alternatively, a low frictional member may be placed between the arm unit and the slide plate for axially sealing the arm unit. Frictional resistance from movement of the lower arm unit is reduced and machining accuracy improved.

Abstract: A system for the protection of amino acid side-chain functional moieties during peptide synthesis, comprising the use of allyl protecting groups, such as, for example, allyl ether, allyl ester, allyl thioether allyloxycarbonyl and allyloxymethyl groups. The present allyl protecting groups do not exert adverse steric effects on peptide bond condensation, and are fully orthogonal to a variety of popular αN-protecting groups, including Fmoc and  t Boc. Moreover, allyl deprotection is mild, and does not result in the formation of reactive carbonium ions. Allyl side-chain protection can be used alone or in conjunction with other types of side-chain protecting groups.

Abstract: In order to produce a stock for electrical contacts, for example relay contacts, a sectioned contact billet in the form of a metal strip and made of readily electroconductive material is applied, by one strip surface side, to a contact carrier strip essentially consisting of copper, by means of resistance heating in a welding circuit so that it is electroconductive and mechanically strong. The strip surface side facing the contact carrier strip has wall-like salients which are separated from one another by groove-like recesses along the running direction of the strip, the tips of the salients being of tapered design and being provided, at least in the tip region, with a coating essentially consisting of silver. In order to produce a semifinished material (blank) for electrical contacts there is produced, in the welding circuit, a high heat output in the salients, which, owing to the amount of pressure applied via electrodes in the welding circuit, leads to melting of the silver coating with subsequent formation of a silver-copper alloy with a melting point in the range of the eutectic between the salients. Opposite that strip surface side of the metal strip which is provided with salients, the strip surface side designated as the eventual working contact is arranged. <IMAGE>

Abstract: In the present invention, an optically active cis type 1,2-diol derivative of the following formula (I) is produced by reacting a cis type 1,2-diol derivative of the formula (I) with a carboxylic acid derivative of the formula (II) in the presence of a lipase:
     
     
       
wherein R 1  and R 2  independently represent hydrogen atom or an alkyl group, X represents a halogen atom, a nitro group, a cyano group, an alkyl group, a haloalkyl group, or a phenyl group, and n represents an integer of from 0 to 5; R 3  represents a C 1  - C 10  alkyl group or an aryl group, and R 4  represents a hydrogen atom, a C 1  - C 5  alkyl group, a C 2  - C 4  alkenyl group, or COR 3 . 
     The cis type means that the bond between the cyclopentane ring and the hydroxy group and the bond between the cyclopentane ring and the benzyl group reside in the same direction as that portrayed on the paper. 
     The optically active cis type 1,2-diol derivative is used as an intermediate for producing an optically active cis type azole derivative of the formula (VII).

Abstract: In the fabrication of a free-standing miniaturized structure in a range of about 10 to 20 µm thick, a method based on a sacrificial system includes the steps of selecting a substrate material, depositing on the substrate material a sacrificial layer 58 of material and patterning the sacrificial layer to define a shape. A photoresist layer 62 of material is deposited on the sacrificial layer and patterned by contrast-enhanced photolithography to form a photoresist mould. Upon the mould there is plated a metallic layer 68 of material. The electroplated structure conforms to the resist profile and can have a thickness many times that of conventional polysilicon microstructures. The photoresist mould and the sacrificial layer are thereafter dissolved using etchants to form a free standing metallic structure in a range of about 10 to 20 µm thick, with vertical to lateral aspect ratios of 9:1 to 10:1 or more.
