Patent EP-0379301-A1 (EP)
Inventor: FUJIMURA SHUZO
IPC: H01L21/027
Filed: 1990-01-10
Abstract: In a method of ashing an organic film on a supporting substrate (8), mounted in a working chamber (6), a gaseous mixture containing oxygen and a halogen is subjected to an ionization process in a plasma chamber (4) from which neutral active species of a resulting plasma can pass into the working chamber (6). Water vapour is introduced into the working chamber at a rate such that the working chamber receives at least one mole of water vapour for every two moles of free halogen atoms received therein from the plasma chamber, thereby to prevent such free halogen atoms from contacting the organic film. 
     Such a method may be used, for example, to remove an organic resist from a semiconductor wafer during the fabrication of semiconductor devices, and can enable the resist to be removed at an acceptably high rate at a desirably low temperature, without causing significant contamination or etching of the underlying wafer.

IPC: C07K1/08

Abstract: A novel and convenient process is described for providing protected amino acids and activating agents for solid phase synthesis which drastically reduces the capital costs of equipment required for the preparation of peptides. The two normally very reactive reagents, when mixed as anhydrous powders are shelf stable and yet form an active compound rapidly when mixed together in solution. This invention presents a method for combining these highly reactive dry solids in a manner which makes them unreactive and shelf stable at room temperature for extended periods of time. Once the solids are dissolved in solvent, a highly reactive amino acid ester that can readily be used in solid phase peptide synthesis is formed. This method of delivery of reagents to an automated peptide synthesizer allows a very simplified instrument to be constructed using fewer and less expensive components and significantly reducing the associated software required.

Abstract: A prior art computerised ultrasonic examination is performed by moving an ultrasonic probe (4) over the surface of an object (2), transmitting short pulses of ultrasonic energy into the material. Combined digital position and echo pulse signals are electronically sto­red, processed, and used for the display of a first vi­deo sectional flaw image (30) of a selected sectional plane through the object. 
     Representatives of reflected echo amplitudes from a chosen location are now shown, either in said first flaw image (30), or in at least one separate sec­tional view (34), as lengths of line segments origina­ting at an image pixel (33, 36) representing said loca­tion, and drawn in the directions of the projections on said selected sectional plane of the incoming pulses at said location. In typical examples it is demonstrated, how reflected waves can be visualised and evaluated, and how the corresponding flaw images (30) can be su­perimposed on said first video flaw image, thereby ad­ding important information which is normally disregar­ded in the prior art. This visualisation can be made on line during the examination or in later post processing and closer analysis of the results of the examination.
Patent EP-0447458-A1 (EP)
Title: Interactive electronic thermostat.
Inventor: BERKELEY ARNOLD D
IPC: G05D23/19
Filed: 1989-12-07
Abstract: An interactive electronic thermostat operates to communicate with an installed through an audible or visual display and keypad to instruct the installer to perform tasks and enter observations to effect proper connections at the thermostat of heater/air conditioner wires in spite of the absence of labels identifying the functions of those wires. The thermostat requires entry of coded indicia representing operator-observed conditions in the system in response to displayed instructions carried out by the operator. Control circuits are automatically assigned functional tasks in response to the operator-observed conditions entered into the system. Different program routines are invoked depending upon the number of system wires and the type of heater/air conditioner being controlled. Under appropriate circumstances, messages are displayed informing the operator/homeowner that the thermostat is incompatible, or has no advantageous use, with the heater/air conditioner. In one embodiment the installer need only connect the wires to the thermostat terminals one time; the thermostat reconfigures its internal connection paths in response to installer-entered indicia to assure proper control of the system.
