Title: Epitaxial passivation of group 2-6 infrared photodetectors
Inventor: COCKRUM CHARLES A
IPC: H01L27/146
Filed: 1989-03-14
Abstract: An array 1 of photodiodes 2 is comprised of a Group II-VI material, such as HgCdTe, which may be selectively doped to form a plurality of diode junctions. Array 1 is comprised of a plurality of photodiodes 2 which are disposed in a regular, two dimensional array. Incident IR radiation, which may be long wavelength, medium wavelength or short wavelength radiation, is incident upon a surface of the array 1. The array 1 comprises a radiation absorbing base layer 3 of Hg<SB>1-x</SB>Cd<SB>x</SB>Te semiconducting material, the value of x determining the responsivity of the array. Each of the photodiodes 2 is defined by a mesa structure, or cap layer 3; or the array 1 of photodiodes 2 may be a planar structure. Each of the photodiodes 2 is provided with an area of contact metallization upon a top surface thereof, the metallization serving to electrically couple an underlying photodiode to a readout device. The upper surface of the array 1 is provided with, in accordance with the invention, a passivation layer 5 comprised of an epitaxial layer of Group II-VI material which forms a heterostructure with the underlying Group II-VI material and which has a wider bandgap than the underlying Hg<SB>(1-x)</SB>Cd<SB>x</SB>Te, thereby beneficially repelling both holes and electrons from the diode junctions.

Patent GB-2225266-A (GB)
Title: Open ended ratchet spanner
Inventor: PASLEY ANDREW
IPC: B25B13/46
Filed: 1989-09-25
Abstract: The open ended ratchet spanner has a shank 1 with open ends 2. The spanner ends have holes 3 which are parallel with the spanner shank, into which bars 4 are slidably fitted. Springs 5 bias the bars towards the spanner ends. When tightening a bolt 6, the bars act as a jaw surface of the spanner to tighten the bolt when the spanner is rotated in one direction. The spanner is then rotated in a reverse direction to cause the bolt to ride over a sloping end of the bar 4, thus providing the ratchet action. <IMAGE>

Title: Pulse modulation of the excitation light source of flow cytometers
Inventor: STEEN HARALD
IPC: G01N15/14
Filed: 1990-11-09
Abstract: A method for increasing the intensity of the excitation light, and thereby the sensitivity, of flow cytometers. The initial part of the signal produced by each cell as it enters the excitation focus (2) triggers a current pulse to the excitation light source (1), with a duration approximately similar to the time required for the cell to pass through said focus (2). This current pulse, which is superimposed on the constant operating current to said light source (1), causes an increase of the intensity of the excitation light during the period when the cell is passing through said excitation focus (2) and thereby an increase of the sensitivity of the flow cytometer. Cell size is measured by light scattering using a detector 12, and cellular content of DNA is measured by spectral fluorescence using detectors 15. <IMAGE>

Title: Non linear optical device for controlling a signal light by a control light
Inventor: TAJIMA KAZUHITO
IPC: G02F1/025
Filed: 1991-04-22
Abstract: A nonlinear optical device (10) for controlling a signal light by a control light comprises a waveguide region (15, 14) consisting of an optical nonlinear semiconductor material, and an electrostatic field generator (18-20). Carriers (electrons and holes) generated by excitation of electrons due to a control light having a predetermined wavelength supplied to the waveguide region are swept away from the waveguide region by the electrostatic field, so that the change of nonlinear refractice index of the waveguide region can follow the change of the control light to increase the operation speed of the non linear optical device. The electrostatic field may be replaced by a magnetic field for sweeping away carriers generated in the waveguide region. <IMAGE>
