Title: Refining magnetostrictive thin layer properties - increases local energy density of thin layer for short period and in pulsed manner
Inventor: HERMANN MICHAEL DIPL PHYS
IPC: H01L43/12
Filed: 1989-11-02
Abstract: In the refining process the local energy density of the thin layer and its near surrounding is powerfully increased for a short period and in a pulsed manner.  The thin layer is brought into a state of higher electric, magnetic, and thermal energy density by electric pulses. The electric pulses are typically generated by a capacitor-discharge device.  The local thermal energy density of the thin layer and its surroundings is heavily increased by application of visible IR, or UV light for a short period and in a pulsed manner.  The same result may be obtained by the applicationof an e.m. radiation in the microwave range. USE/ADVANTAGE - Magnetoresistive coders, position, or angle sensors etc., with improved dynamics of megnetoresistive effect in simple manner.

USE/ADVANTAGE - Prevents thermoplastic particles clinging to the die outlet surfaces during extrusion of wide strip, e.g. films thus improving prod. surface quality.
Patent DE-3942490-A1 (DE)
Inventor: KOREC JACEK DR ING
IPC: H01L29/749
Filed: 1989-12-22
Abstract: In order to combine the good transmission characteristics and good control characteristics of a MOS-controlled thyristor (MCT) wiht the resistance to shorting of an insulated-gate transistor (IGT), at the same time broadening the safe operating area (SOA), the invention calls for one or more auxiliary emitter zones (7), which have no external electrical contacts but are controlled by non-dissipative field-effect techniques, to be integrated with each other. The cathode-contacted emitter (6) extends over the whole cathode contact (10) and forms, together with the second base region (4, 5), a diode structure. When a control signal is sent to the integrated MOS-FET, the auxiliary emitter (7) and the integrated diode (4, 6) ensure that flooding of the component with charge carriers is intensified. The second base region can include a voltage pick-up zone (3). In this case, the first base region (2) is more highly doped than the voltage pick-up zone (3).

Patent DE-4023878-A1 (DE)
Title: Equipment for thermo-forming plastic film - by smoothing back of film when heated by blown hot air system which is uniform and can also apply cooling air and save energy
Inventor: HOELZL EMIL
IPC: B29C41/04
Filed: 1990-07-27
Abstract: Equipment for thermoforming plastic films has a radiation-heated mould at one station, applies the film to the mould tool at another station, and removes the moulded film from the cooled tool at a third station; the back of the film, however, is smoothed with a cap fitted with a heater after the film has been fused on the heated mould tool; the heater is a hot air type with a heated air holder and bores for fresh and/or surrounding air. More specifically, the bores in the smoothing cap are near to its surface and they produce a more uniform heat distribution than radiation heaters. Moreover the system reduces weight. The moulding tool is normally rotated several times near to the smoothing cap and this has the disadvantage of risk of dirtying the film; moreover a radiation heater might be damaged. The heat store can be heated up while the smoothing device is stationary. The fan for the hot air can be driven by a battery. The air bores can be used for cooling as well as heating. This arrangement saves energy. ADVANTAGE - The heating system is efficient (and more so than in existing equipment of this kind).

Title: Fluid concn. evaporator plant operation partic. for aq. brine solns. - evaporated fluid vapours exit through apertures whose cross=sectional area is directly proportional to level of concentrate in collection pan
Inventor: MAGDY EL-ALLAWY MOHAMED
IPC: B01D1/28
Filed: 1990-11-15
Abstract: An evaporator plant in which fluid is conc. includes a chamber in touch via a heat exchanger with a heat source, and in which vapour rises to leave concentrate before being compressed and heat then recovered. The vapours leave through apertures whose cross-section area is directly proportional to the level of concentrate in the collection pan and pressure loss. Cross-sectional area varies with concentrate level, directly proportional to the effective temperature difference between the heating chamber and the vapour chamber, and the vapour chamber in the heat exchanger. Mass flow of vapour is directly perpendicular to the level of concentrate. During the start-up phase, the cold air in the evaporator is compressed and transferred via a bypass and is then exchanged between the heating chamber and vapour chamber until the working temperature has been reached.

Title: Multiple disc drive assembly - compensates for mechanical mis-alignment introduced by unequal expansion effect of component materials
Inventor: CAP HEINRICH
IPC: G11B33/14
Filed: 1991-02-08
Abstract: In order to ensure that the height (33) of the read/write head support axle (34) w.r.t. the height (32) of the disc hub (1) remains constant, temp. gradients and the thermal expansion coefficients of component materials must be considered. The steel bearing bush (2) and aluminium disc hub (1) are mounted on a spindle in the centre of the drive unit where temps. are nominally higher than those found at the sides where the aluminium alloy head support axle (34) is positioned. The slightly tapered steel bearing bush (2) allows a relative friction free expansion of the disc hub (1) between upper and lower bush areas. The bonding surface (7) is selected to achieve fine adjustment, as its position affects the overall change in length of the disc hub (1). Additional bearing support surfaces (9,10,11) can be used according to the length of the steel bearing bush (2). USE/ADVANTAGE - Accurate and trouble free access to disc data -consideration of temp. and material expansion coefficients allow overall size of disc drive unit to remain small.
