Disclosed herein is a circuit for charging a battery having opposed terminals, which circuit includes a relatively rotatable magnet and charge coil for generating charging potentials of alternating first and second polarities, the charge coil having first and second terminals, a diode having an anode connected to the first terminal of the charge coil and a cathode adapted for connection to one of the battery terminals, whereby to afford application to the battery for charging purposes of the pot...

Polyprenyl derivatives having the formula ##STR1## [wherein A and B individually represent a group of the formula --CH.sub.2 OR.sup.1 (wherein R.sup.1 is hydrogen atom, an alkyl group having an intervening hetero atom in the carbon chain, carboxyl group on its salt or an aliphatic acyl group optionally having an intervening hetero atom in the carbon chain, an aromatic acyl group, a heterocyclic acyl group, an araliphatic acyl group, a heterocyclic aliphatic acyl group or a radical of an inorgani...

Method for forming a CMOS transistor in a silicon layer positioned above an underlying buried oxide layer including isolating a first active area and a second active area; forming an n-well and a p-well having specified back gate threshold voltages; forming gates over the wells; forming a lightly doped drain region in the p-well that extends through the silicon layer; and implanting ions to form a source and a drain region in the p-well to provide a lightly doped drain drift region.

Light olefins are converted to heavier hydrocarbon products, e.g., those boiling in the gasoline, distillate and/or lube range, over zeolite MCM-22 catalyst.

Disclosed herein are processes for polymerizing ethylene, acyclic olefins, and/or selected cyclic olefins, and optionally selected olefinic esters or carboxylic acids, and other monomers. The polymerizations are catalyzed by selected transition metal compounds, and sometimes other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations, block copolymers can be readily made. Many of the polymers produced are often novel, particularly in regard to the...

A lens barrel comprising a first member formed with a guide groove, and a second member having a main protrusion inserted into the guide groove and moving relative to the first member along the guide grove by moving the main protrusion within the guide groove. The lens barrel further comprises a displacement protrusion provided in a position, different from a position provided with the main protrusion, on the second member in a direction perpendicular to the guide groove. The displacement protru...

Hydroxy diester compounds are obtained by esterification between malic acid or tartaric acid and a saturated, aliphatic alcohol of 16 or more carbon atoms having side chains. These compounds are a colorless, odorless synthetic oil with low cloud point, which have a wide range of from low viscosity to high viscosity depending on the starting materials. Said synthetic oils are useful for basic oils or emulsions in the fields of cosmetics, detergents and medicinal preparations.

A method for producing a potassium paradiphenyl phosphino sulfonate ligand which comprises reacting potassium diphenyl phosphide with a lithium salt of para-chloro benzenesulfonic acid in the presence of tetrahydrofuran at elevated temperatures.

A device for suppressing voltage fluctuation and higher harmonics of a power system which supplies power to a load with large power fluctuation and higher harmonic current. The device includes a self-commutated converter and a higher harmonic filter, both provided in parallel with the load. The device includes a first calculation circuit which calculates a reactive power consumed by the load based on a load current and system voltage and generates a fundamental harmonic current command value to ...

There is provided a process for the direct partial oxidation of methane with oxygen, whereby organic compounds comprising higher hydrocarbons are produced. The catalyst used in this reaction is a ZnZSM-5 catalyst. This catalyst may be prepared by ion exchanging or impregnating a ZSM-5 catalyst with a suitable zinc salt such as zinc nitrate.
