Patent EP-0031706-A2 (EP)
Inventor: SHIGEKI NOZAKI
IPC: G11C29/56
Filed: 1980-12-22
Abstract: An address pattern generator (10) generates an address pattern which successively specifies the X-Y addresses of each memory cell of a semiconductor memory device (14) which is to be tested. An address changeover part (11) accesses the semiconductor memory device (14) with the address pattern supplied by the address pattern generator (10) in a normal mode, and accesses the semiconductor memory (14) with an address pattern supplied by the address pattern generator (10) in which predetermined addresses are interchanged in a swap mode. A comparator (13) compares data read-out from the semiconductor memory device (14) with an expected value to detect hardware error, and a fail memory device (12) stores information concerning the existence or non-existence of hardware error in each of the memory cells of the semiconductor memory device (14) into an address region corresponding to that of the semiconductor memory device (14). The semiconductor memory device (14) and the fail memory device (12) both receive common X-Y addresses from the address changeover part (11). The comparator (13) is inhibited in its comparing operation by a signal supplied from said fail memory device (12) for the memory cells of the semiconductor memory device (14) corresponding to the memory cells of the fail memory device (12) which have information stored therein indicating the existence of hardware errors.

Abstract: The output buffer circuit is capable of taking three output states, high level, low level and high impedance. 
     The buffer circuit includes a detector circuit (Zener diode D 3 , resistors R 5  and R 6 , and transistor Q 5 ) for detecting power source voltage (Vcc) applied to the buffer circuit. When the power source voltage becomes high (e.g. 7V) the detector circuit (D 3 , R 5 , R 6 , 0 5 ) switches the buffer circuit to high impedance output state (diode D 3  is turned ON, so that transistor Q 5  is turned ON to connect the collector of a transistor Q 2  to ground G and to turn the output stage transistors Q 3 , Q 2 , Q 4  OFF).

Abstract: Um das Auflegen eines von einer manuell betätigten sogenannten Saugpistole angesaugten Multifilamentes an Streckrollenaggregaten in Streckspul-oder Spinnstreckspulmaschinen zu ermöglichen, sind je nach Verfahren für das Ansetzen an Streckrollenaggregaten, die sich in übermannshohen Lagen befinden, Hilfsmittel notwendig. Ein erfindungsgemässes Hilfsmittel besteht darin, dass ein Streckrollenaggregat (4) auf Führungsstangen (9) aus einer Betriebsposition nach unten in eine Filamentübernahmeposition verschiebbar ist. Ein um weniges schwereres und durch ein Seil (15) mit dem Streckrollenaggregat (4) verbundenes Gegengewicht sorgt dafür, dass das Streckrollenaggregat auch bei Ausfall einer pneumatischen Steuerung in der oberen Anlage bleibt, sowie, dass die Verschiebekräfte sich im wesentlichen auf die Differenz der beiden Gewichte beschränken müssen. Eine elektropneumatische Steuerung steuert im wesentlichen die Verschiebegeschwindigkeit des Streckrollenaggregates aus der Filamentübernahmeposition in die Betriebsposition, um ein Bruch des am Streckrollenaggregat angesetzten Endlosfilamentes beim Hochschieben des Aggregates zu vermeiden. Zum Verschieben des Gegengewichtes dienen Pneumatikzylinder (21). Ein Streckrollenaggregat (3), sowie eine Spulvorrichtung (5) sind in bedienbarer Hohe angeordnet.

Abstract: A majority carrier ballistic conduction transistor is fabricated with a built-in difference in barrier height (0a, 0b) between the emitter/base and collector/base interfaces by employing surface Fermi level pinning in a crystalline structure with three coplanar regions of different semiconductor materials. The central region base 3 has a thickness of the order of the mean free path of an electron- The matenals of the external regions (2. 4) are such that there is a mismatch between the crystal spacing of the external regions and the central region which causes the Fermi level of the material in the central region to be pinned in the region of the conduction band at the interfaces with the external regions and the material of the external regions is selected so that the surface Fermi level is pinned in the forbidden region. A monocrystalline structure having an emitter region (2) of GaAs. a base region (3) of InAs or W 100Ato 500Athick and a collector region (4) of GainAs provides switching in the range of 10 -12  seconds.

Abstract: The invention relates to a method of liquefying a gas, in particular a natural gas by cooling it under pressure in stages, of the kind comprising cooling the gas by means of at least two refrigerants, one refrigerant circulating in a closed refrigeration circuit and another refrigerant circulating in another closed refrigeration circuit, wherein the compositions of the various refrigerants differ from each other. According to the invention a compressor in a closed refrigeration circuit is driven by a gas turbine and the refrigerant circulating in the last mentioned closed refrigeration circuit is cooled by ambient air after compression. Furthermore, according to the invention, in addition to the compressor an electricity generator is driven by the gas turbine in such a manner that, when extra gas turbine power is available because of a variation of the ambient air temperature, so much electric power is generated that the gas turbine is caused to operate at, or at about, its design load. Said electric power is passed to an auxiliary electric motor coupled to a compressor with driving means in another closed refrigeration circuit, so as to deliver extra driving power to said compressor. The invention relates moreover to a system for carrying out the method according to the invention (see drawing).

Abstract: A method, timing control circuit, and power supply are described for initiating arc discharge between the cover gas delivery shroud and lead wire held in the bonding tool of a lead wire bonding machine for melting and forming a ball at the end of the lead wire. An arc discharge timing control pulse controls duration of the arc discharge within an empirically determined time window between the shortest and longest durations of arc discharge which result in optimal ball formation of a substantially spherical ball at the end of the lead wire without necking of the lead wire above the formed ball. The timing control circuit also provides an initial cover gas movement delay before ball formation for displacing oxygen from the shield and the end of the lead wire, and a subsequent cooling delay for solidifying and cooling the formed ball in the cover gas stream prior to ball bonding. Initially, the lead wire tail length extending below the bonding tool is selected to provide a ball of specified size; the voltage is selected according to tail length to form the mass of tail length metal into a substantially spherical ball; and a neck of desired thickness is selected by adjusting the duration of the arc discharge timing control pulse within the time window.
