Patent DE-4316185-A1 (DE)
Inventor: BREITLING WOLFRAM DIPL ING
IPC: H03K17/082
Filed: 1993-05-14
Abstract: A circuit arrangement for switching a current-consuming apparatus 10 on and off has a control circuit 23, 25, 28, 29, 32 which determines the control signal 30 supplied to a switching transistor 11 at a value which permits a maximum current flow through the switching transistor 11. The maximum permissible current may be limited to a value which prevents destruction of the switching transistor 10 as a result of a departure from the safe operating range. A monitoring circuit 15, 16, 17, 18 is provided, which detects an overcurrent condition and in dependence thereon reduces or totally cuts off the control signal 30. A timing element 21 provides a delay so as to enable a temporary increase in current through the transmitter 11 during turn on. The switching transistor 11 may be a FET or a bipolar transistor. Transistor 16 is shown thermally coupled to the switching trnnsistor 11. In an alternative arrangement a limiter diode (41, Fig 2) is connected in series with the base of the transistor 16 which is connected to the control electrode of the switching transistor 11. In a further arrangement the delay is provided by a circuit (42, Fig 3) connected in series with the transistor 16. A microprocessor 19 may provide the control. <IMAGE>

Title: Method and arrangement for utilising and storing solar energy
Inventor: GOEBEL FRANK DR
IPC: F24D11/02
Filed: 1993-06-04
Abstract: The invention relates to a method and an arrangement for combined storage and tapping of solar energy using a buried accumulator, while providing the possibility of utilising hitherto unused radiant energy in the range of low insolation quantities when a heat demand arises. This object is achieved by the arrangement according to the invention which allows direct supply of the solar heat for water heating and to the accumulator (storage) and, in the event of a heat demand which exceeds the solar supply and is covered by emptying the accumulator, allows solar heating (pre-heating) of the heat transfer medium leaving the heating-water heat exchanger or the evaporator of the heat pump in the case of any heat-pump heating system, before entering the accumulator. <IMAGE>

Title: Gallium arsenide phosphide epitaxial wafer - has low probability of crack formation during LED mfr.
Inventor: SATO TADASHIGE
IPC: H01L21/20
Filed: 1993-06-09
Abstract: In a GaAsP epitaxial wafer, obtd. by producing a first GaAsP mixed crystal layer with varying mixed crystal ratio on a GaP single crystal substrate and then producing a second GaAsP mixed crystal layer with constant mixed crystal ratio, a difference in the mixed crystal ratio of the second layer is produced so that the mixed crystal ratio of the layer facing the substrate is 0.01-0.05 less than that of the surface side. USE/ADVANTAGE - The wafer is used esp. in LED mfr.. It has reduced residual stress level, and thus reduced probability of crack formation during processing to mfr. LEDs. The substrate has a crystallographic surface orientation along the (100) plane or at an angle of 2-100 deg. in the 110 direction relative to the (100) plane. The second layer is produced by gas phase epitaxy and consists of two sub-layers with different mixed crystal ratios.

Patent DE-4436787-A1 (DE)
Inventor: KYNAST JUERGEN
IPC: C05F17/00
Filed: 1994-10-14
Abstract: Fermented fungus soils have so far been produced in batches by a spontaneous succession of aerobic, thermophilic microflora, especially for growing oyster and Paris mushrooms. The process takes between 2 and 14 days. The novel process is based on the fact that, by separating part of the liquid phase of the fermented medium and the suspended micro-organisms in the liquid phase after or during microbiological reaction, an inoculum is obtained with which can be added to the medium still to be fermented. This partial return of substrate water concentrates micro-organisms, water soluble nutrients and heat in the medium at the start of fermentation and depletes them on the conclusion of fermentation in the medium. The rate of metabolism of the micro-organic population is thus increased and the fermentation time required can be reduced to the extent where the process can be run continuously. USE: The continuous production of selective fungus growing media.
