A laser has an active element (16) comprising one or two quantum wells (16 min ) in a cavity formed by two distributed feedback mirrors (13,18), each composed of alternating layers (14,15) of higher and lower refractive index. The threshold value, and therefore the power dissipation, is low, making the laser a good candidate integration.

A method of mechanically imparting a surface texture to a blank surface of sheet metal, especially soft aluminum, in which an adherent foil is applied at least to one surface of the sheet metal and is pressured into and against a surface by a roll so that the sheet metal is deformed and the pattern of the deformed foil is pressed into the sheet metal surface.

An internal combustion engine includes a moving piston within a combustion chamber that is temporarily divided into two zones when the piston is at and near its minumum volume position. Fuel is confined to a first zone where the fuel is ignited to generate combustion wave energy that drives gas within the second zone in Helmholtz resonance through a restricted passageway. Air from the second zone ...

Disclosed are amorphous silica-alumina spherical particles having a notched surface. The particles have a small specific surface area and a highly controlled hygroscopic property. The spherical particles are obtained by exchanging at least a part of an alkali metal ion of a P-type zeolite as the starting material with a divalent metal and firing the ion-exchanged zeolite. Since the pH value is shi...

The invention relates to the control of a system for automatically manoeuvring a clutch from the manoeuvring linkage of the hand brake.
