Granted: 1987-01-08
Abstract: 1. A fingerprint sensor delivering an electrical signal corresponding to the papillary pattern of the skin of a finger (2) to be examined, comprising an elastic contact surface (20) designed on one side of a transparent body (18) for impression by the finger (2), wherein the respectively impressed papillary pattern produces a corresponding topographic relief by elastic deformation, which relief can be illuminated by a light beam (9) supplied to the contact surface through the transparent body (18) and reflected from the illuminated relief, where the reflected light beam is modulated in accordance with the illuminated relief and supplied to a light-sensitive field (28) of an opto-electric detector device (30) for detecting the distribution of the light intensity incident upon the field (28), which device (30) produces an electrical signal (a) which corresponds to the topographic relief and simultaneously corresponds to the impressed papillary pattern, characterised in that the light beam (9) supplied to the contact surface (20) through the transparent body (18) is supplied to the contact surface (20) through a partially-reflective surface (12) of a beam-splitter (10), which is arranged at an angle of 45 degrees to said contact surface, in such a manner that it is vertically incident upon the contact surface (20) and illuminates the relief, and that in the light beam (21) reflected from the illuminated relief and supplied to the light-sensitive field (28) by means of reflection on the partially-reflective surface there are arranged both a focussing optical system (24) for focussing a real image of the illuminated relief on the light-sensitive field (28) and a spatial frequency filter device (26) which allows the predominant spatial frequencies in the relief to pass through to the light sensitive field (28), but greatly suppresses residual spatial frequencies.

Title: Control method for an inverter working with pulse width modulation, and device for carrying out this method
Inventor: DETEMMERMAN BERNARD
IPC: H02M7/5387
Filed: 1982-09-22
Granted: 1988-02-11
Abstract: The circuit of the control device consists of two branches generating the waveforms for three-phase edge-controlled flip-flop sampling units followed by correctors which produce clean width-modulated pulses. The upper branch of the control circuit contains a HF square-wave generator whose output is divided by 96 and amplitude-regulated by a unit connected to a desired-value generator. A filter (14) produces a sinusoidal signal at about 100 kHz for comparison with the chopping signal from a triangular-wave generator. In the lower branch a fundamental signal is generated and synchronised with the square wave, to which it is added before division into three sampling signals at 120 deg. phasing. The correctors of the sampled waveforms eliminate multiple transitions. The circuit controls a three phase asynchronous motor.

Title: Process for forming iii-v semiconductor mesfet devices, having self-aligned raised source and drain regions
Inventor: ANDRADE THOMAS L
IPC: H01L29/812
Filed: 1982-11-23
Granted: 1988-03-10
Abstract: A process for forming III-V semiconductor MESFET devices having self-aligned, raised source and drain regions is disclosed. A preferred embodiment relates to a process for forming gallium arsenide MESFET devices. A feature of the invention is placing a gate structure 5 on the gallium arsenide substrate 2. Then a process including molecular beam epitaxy, grows epitaxial gallium arsenide on each respective side of the gate 5, forming a raised source region 8 and a raised drain region 9. Gallium arsenide will not grow in a conductive state on top of the tungsten gate metal 5. The resulting MESFET device has a raised source 8 and drain 9 which significantly reduces the high resistance depleted surface adjacent to the gate which generally occurs in planar gallium arsenide MESFET devices. Furthermore, the MESFET channel region which is defined by the proximate edges of the source and the drain, is self-aligned with the edges of the gate by virtue of the insitu process for the formation of the source and drain, as described above.
