Title: Nonwoven microfibre for lamination to give textile character - has a component in fibres which is tacky through heat and reactivated by further heat for adhesive bonding to a substrate
Inventor: WEHRLE MYRTHA DR
IPC: D04H5/06
Filed: 1991-05-07
Abstract: The non-woven composed of short and fine micro-fibres, produced by melt blown process especially to give a micro fibre felting, uses micro fibres of one or more components of an adhesive or polymer which becomes tacky when heated.

The micro fibres are heated to a temp. lower than the melting or destruction point of material to be bonded on reactivation, using a reactivation temp. of 80-180 degC. and pref. about 100 degC. The micro fibres are of ethylene butyl acrylate, ethylene methyl acrylate, or a mixture of both. The micro fibres have a dia. less than or equal to 10 microns. The material can be made of generally continuous coarse filaments and chopped micro fibres with a small dia. to be mixed together in one or two layers. USE/ADVANTAGE - The material is for lamination to give a textile character. The material gives a firm bond to the substrate without any negative accompanying effects.

Title: Laser diode reliability determn. method - measuring noise current in region of threshold current for several frequencies to determine inverse frequency noise
Inventor: STORM HARTWIG DIPL ING
IPC: G01R31/26
Filed: 1993-07-29
Abstract: The inverse frequency noise of the laser diode (DUT) is determined by measuring the noise current.

The decrease in the noise current at low frequencies is used as a criterion for the laser diode's reliability. For a drop of at least 3 dB in the noise current in the region of +/- 20 per cent deviation of the forward current from the threshold current, an evaluation unit signals that the laser diode is reliable. USE - Positive indication of reliability of laser diode still on its semiconducting wafer immediately after its mfr.
