Patent DE-3914348-A1 (DE)
Title: Method of drying or thawing open air surfaces - involves forward mounted mobile air mixer with heater and blower to blow warm air on to surface
Inventor: KOCH CHRISTIAN DR ING
IPC: E01H5/10
Filed: 1989-04-29
Abstract: The method is of drying, heating, thawing, or cleaning open air surfaces by warm air. The air is heated in a mixer (1) and  quickly sucked up by a cold upper air stream to be mixed behind the outlet nozzles.

Title: Seal-sealing coupling for injection moulding machine temp. control - simpler construction provides constant cross=section with subsequently more uniform temp. control
Inventor: HEUEL OTTO
IPC: F16L37/34
Filed: 1989-06-05
Abstract: A self sealing coupling suitable for temp. control fluids in an injection moulding machine has a socket and matching plug, both of which have a valve seat and body whose closure position is effected by a spring. The circular surface of the valve body and the annular valve seating surface surrounding it lie in a common plane. During the connecting operation of the fluid lines the valve bodies and seats of the plug and socket are mutually guided into each other to effect an open valve condition. Separation of the connector is leakage free and requires no additional constructional expense.  In the coupled condition a constant cross-section is always achieved. USE/ADVANTAGE - The coupling is suitable for use in temp.  control lines in plastics injection machines. Construction of the coupling is simpler and a constant cross-section provides uniform fluid flow and better temp. control.

Title: Preventing frothing of heavily carbon di:oxide charged drink - after filling interruption by applying alcoholic soln. to feed pipe interior and exterior
Inventor: HUELS PETER
IPC: B67C3/00
Filed: 1989-08-30
Abstract: On recommencing after a long pause e.g. overnight, the filling of containers for drinks with a high CO2 content by the injection of liq. through a feed pipe (4), forming point e.g. of a bottle feeder system, the resulting frothing by released gas can lead to loss of liq and to filling machine soiling. Such frothing is countered by at least a single spraying of both exterior and interior of the feed pipe with al:coholic soln. at least 70% concn, and pref denatured by methyl-ethyl-ketone. The soln, periodically delivered from a supply cylinder (27) by a membrane pump (25) is applied to the feeder exterior by a flat broad nozzle (16) while a second nozzle (17) injects a slender vertical jet into the feeder interior. USE: Esp for wines such as SERT with about 8-12 gm CO2/l.

Title: Bipolar transistor with large band-gap emitter material - uses single crystalline silicon as emitter and collector and forms base-region from silicon-germanium cpd.
Inventor: BENEKING HEINZ PROF DR RER NAT
IPC: H01L21/331
Filed: 1989-09-13
Abstract: The bipolar transistor uses as base-region (2) a Si-Ge cpd., with the compsn. Si(X)Ge(1-X) and a value of X from 0.05-0.2 (0.1), which has been deposited by low pressure vapour phase epitaxy (LPVPE). The emitter (3) material is single crystalline Si, pref. deposited after the base-material by LPVPE. The selective depsn. of base and emitter regions is achieved by using a masking layer (4,5) of thermal or pyrolytically deposited SiO2 or of Si-nitride. USE/ADVANTAGE - The construction combines the advantages of an emitter material with a larger bandgap than the base-material with that of good lattice-fit allowing single crystalline material, to be used. This results in low leakage currents and lower resistivity. The emitter, doped e.g. to a level of 10 power 17 cm (-3), has a gap of 1.1 Ev, the base material has a gap of 1.0 Ev. The devices are used for HF operation or as fast switching transistors.

Inventor: TOBITA YOUICHI
IPC: G11C29/00
Filed: 1990-01-30
Abstract: A semiconductor memory device comprises a high voltage detection circuit (20). A sense amplifier driving signal generating circuit (92) delays a word line driving signal (R) and outputs the delayed word line driving signal (R) as a sense amplifier driving signal ( phi s). An X decoder (300) applies the word line driving signal (R) to any of word lines (WL). A sense amplifier (510) amplifies potential difference between a bit line pair (BL,  &upbar& B) in response to the sense amplifier driving signal ( phi s). The high voltage detection circuit (20) generates a test signal (T) when high voltage is applied to an input terminal (81) during a test. A delay time of the sense amplifier driving signal generating circuit (92) is reduced in response to the test singal (T).
