A technique for measuring the ion implant dosage involves method and apparatus for directing pulses of coherent radiation from a laser to the surface of a semiconductor that has been subjected to ion implant. The intensity of the third harmonic reflected from the semiconductor is determined and correlated to determine the ion dosage within the semiconductor.

A rectangular mattress support frame has side rails formed of rail sections which are pivotally interconnected for movement between a folded seating position and an unfolded sleeping position. In the sleeping position, side rail portions projecting forwardly of the furniture frame are supported on a forward support leg and a center support leg. When a first rail section at the forward end of the s...

A PNPN layer type gate turn-off thyristor including a first gate and a second gate comprises, in particular, a second P-type layer such that the impurity atom concentration at the auxiliary thyristor portion is lower than that at the main thyristor portion. Since the first gate disposed at the auxiliary thyristor portion is first fired and then the main thyristor portion is turned on, the above-me...

A ski binding of the multidirectional-trip type for obtaining a reduction in elastic resistance to rotational displacement in the event of a thrust exerted by the ski boot and in the event of upward disengagement of the boot. The ski binding comprises a boot-retaining jaw unit pivotally mounted for vertical displacement on a body which is rotatably mounted on a vertical pivot. The rotary body is m...

A process for preparing pulverulent ethylene homopolymers or copolymers with a grain size of less than 200 mu m which comprises contacting coarse-particled ethylene homopolymers or copolymers in the form of a suspension with an aliphatic ketone containing 3 to 10 carbon atoms, heating the same with a mixture of said ketone up to a temperature above the softening point of the polymer and thereafte...

Process for the gasification of fossil fuels and the reforming of a gaseous fuel in order to manufacture a gas containing chiefly H2 + CO whose content of H2O + CO2 is lower than 10% and whose hydrogen content can be raised above that which corresponds to the composition of the fuel. An oxidising agent and a fuel are injected into a reaction chamber 2 while external energy is supplied by at least ...

A storage stable aqueous dispersion useful in the curing and foaming of unsaturated polyester resins containing an aromatic diacyl peroxide, an alkali metal carbonate or bicarbonate and dispersion-stabilizing amounts of magnesium aluminum silicate and an alkali metal carboxymethyl cellulose. Also disclosed is the preparation of foamed polyester resins using the dispersion.

1. A method for sealing concrete and natural stone against attacks by acid media, by treating the stone surface with an aqueous fluorosilicate solution, characterized in that the stone surface impregnated with the fluorosilicate solution is treated with an alkaline solution or suspension of a calcium compound.

Biaxially drawn polyamide films having an excellent levelness are prepared as follows. A substantially unoriented polyamide film is heated at 45 DEG -65 DEG C., and then drawn in the longitudinal direction at a deformation rate of at least 10,000%/min. and a draw ratio of 2.7-3.5 by a roll stretcher. The drawn film is immediately transferred to the lateral drawing position at 45 DEG -60 DEG C. w...
