Title: Apparatus for binding thread running through button sewed on garment
Inventor: SUH MYUNG WON
IPC: A41H37/10
Filed: 1998-05-30
Abstract: An apparatus for binding a button-fixing thread (12) running through a button (10) sewed on a garment or other fabric, which is capable of winding a binding thread (56) around the button-fixing thread by several turns in a safe, simple, easy and convenient manner while forming a twist with the binding thread at every turn, thereby not only preventing the button from being separated due to a loosening of the button-fixing thread (12) during a strong washing operation or an operation of passing the button through a button slit formed in the garment, but also achieving an improvement in the binding operation and an improvement in the reliability in use. The apparatus includes a thread hooking plate (44) adapted to hook the binding thread (56) to be wound around the button-fixing thread (12) when the drum (26) rotates, a twisting member (52) adapted to twist the binding thread hooked by the thread hooking plate (44) and to separate the twisted binding thread from the thread hooking plate (44) after the thread hooking plate rotates by a predetermined angle, and a twist forming member (54) adapted to hook the binding thread (56) twisted by the twisting member (52) after the twisting member rotates by a predetermined angle, thereby forming a complete twist with the binding thread (56).

Title: Process for fabricating organic semiconductor devices using ink-jet printing technology and device and system employing same
Inventor: YANG YANG
IPC: H01L51/30
Filed: 1998-10-14
Abstract: An emission system for presenting visual image is disclosed. The emissive system typically contains first electrodes (90) deposited over and in contact with a substrate. One or more conjugated organic buffer layers (40) are then deposited over and in contact with the first electrodes, and second electrodes (22) are subsequently deposited over the conjugated organic buffer layers. The conjugated organic buffer layers (40) regulate current flow between the first electrodes (90) and the second electrodes (22). Either before or after the deposition of each conjugated organic buffer layer (40), but before the deposition of the second electrodes (22), conjugated organic deposits (34, 36, 38) are ink-jet printed such that they are in contact with at least one conjugated organic buffer layer. The conjugated organic deposits (34, 36, 38) help to generate an indicator when a voltage stimulus is applied across the first electrodes (90) and the second electrodes (22). Depending on the material of the conjugated organic deposits (34, 36, 38), the indicator may be luminescence fluorescence, conductivity, or the like. A voltage source is used for selectively applying the voltage stimulus across the first electrodes (90) and the second electrodes (22).

Patent CA-2312467-A1 (CA)
Inventor: RAMASAMY ALAGIRUSAMY
IPC: D04H3/04
Filed: 1996-03-11
Abstract: A method for producing flexible, low-bulk towpreg which involves powder coating a bundle of unspread fiber tows (35) arranged in a predetermined cross-sectional shape, and the resulting towpreg. During the powder coating process, the resin powder particles do not enter into the fiber bundle, but rather only coat the surface fibers comprising the tows, resulting in dry fibers in the core of the towpreg and outer fibers which are coated with a discontinuous sheath of resin on the surface of the towpreg surrounding the core of dry fibers. The resin layer on the surface of the towpreg is formed by a partial melting of the powder particles. A post-treatment process can be used to convert flat ribbon towpreg produced in accordance with the present invention into flexible unidirectional tape.

Inventor: HOWARD CAROL A
IPC: G01J5/08
Filed: 2000-08-09
Abstract: A vernier ratchet-type lens adjuster for use with a lens array allows for fine adjustment of the coverage pattern of a sensor. The lens array can have notches, or teeth, that interact with a single tooth, or pawl, of a lens adjuster unit to maintain the position of the lens array. A user can make fine adjustments to the coverage pattern of the sensor by moving the lens array small increments.  Alternatively, a rack and pinion type vernier adjuster can be used. One edge of the lens array has notches, forming the teeth of a rack portion. A pinion, or gear, has compatible teeth for mating with the rack portion. The pinion has a knob or screw accessible from a port in the sensor housing. When assembled, the rack, pinion and lens array are mated. A user can adjust the coverage pattern of the lens array by rotating the pinion, which in turn moves the rack, or the lens array, along a predetermined path.
