Patent EP-0420518-A2 (EP)
Inventor: ASARS JURIS ANDREJS
IPC: H05B44/00
Filed: 1990-09-21
Abstract: A power saving voltage drive circuit for a TFEL edge emitter device of the type having a plurality of pixels, with each pixel having a first terminal and all pixels on a device sharing a common second terminal, is comprised of a demultiplexing channel driver being select­ively connected to the second terminal. A bidirectional switch selectively connects one of the first terminals to a source of voltage thereby enabling current to flow into and out of the pixel. A transformer has a primary winding connected between the first terminal and the bidirectional switch for enabling the pixel to charge to an operating voltage, and a secondary winding connected in series with a diode across the source voltage and ground for limiting the value of that operating voltage. The bidirectional switch is operated so that a substantial portion of the energy used to charge the pixel is returned to the source of voltage at the end of the pulse duration.

Abstract: A plurality of coated strands (14) are conveyed through a drying oven (26). A plurality of nozzles (48) impinge the upper surface of the coated strand as it passes therethrough. Baffle plates (54) positioned below the strands redirect the gas stream such that, after the gas stream has passed through the strands, it is redirected so as to impinge on an opposite surface of the coated strand. The strand is supported by positioning it between an additional pair of nozzles (82) that are tilted towards each other such that an upwardly directed gas stream issuing from the first nozzle intersects an upwardly directed gas stream issuing from the second nozzle along a line which along with the strand, forms a generally vertical plane. The combined upwardly directed force from the gas streams lifts and supports the strand while the opposing lateral force from each gas stream on the strand tend to reduce and lateral movement and stabilize its relative position.

Abstract: The present invention relates to a method of depositing anti-doming material of a shadow mask. The method includes in the preferred embodiment the step of heating boron in a vacuum atmosphere of 5 x 10⁻⁵ Torr at 2500 - 2600°C for 12 - 20 sec to deposit a boron layer of 1µm on the surface of a shadow mask and introducing nitrogen gas for 12 -20 sec with maintaining the vacuum level of 10⁻⁴ Torr to form a boron nitride layer of 2µm. Titanium is then deposited in a vacuum atmosphere of 5 x 10⁻⁵ Torr at 2400 - 2600°C for 25 - 35 sec to form a titanium layer of 1 - 2µm on the boron nitride layer. The boron nitride layer having low thermal expansion coefficient prevents deformation by doming and the titanium layer having the good conductivity enables the anode voltage to be applied to the shadow mask.

Abstract: A chuck has a spring connection between the nut which rotates to advance or retract the jaws (40) and the control ring or sleeve (110) which the user rotates to operate the chuck. The spring (140) normally transmits tightening or loosening rotation from the sleeve to the nut. When the jaws (40) contact a tool, however, the spring (140) allows the sleeve (110) to continue to rotate even though the nut (50) is stopped by the jaw-tool contact. Continued rotation of the sleeve (110) relative to the nut (50) causes a cam mechanism (80) interposed between these two elements to force the non-rotating nut axially forward. This applies a final tool-gripping force to the jaws.
