Patent EP-0049764-A2 (EP)
Inventor: NELLE GUNTHER DR-ING
IPC: G01D5/26
Filed: 1981-09-10
Abstract: An incremental length or angle measuring instrument includes a scale having a line grid and a plurality of reference marks. A scanning unit is provided with a plurality of photosensors to scan both the line grid and the reference marks. A reference mark selecting arrangement is described which includes a light source and a photosensor. This selecting arrangement acts to select a subset of the reference marks from the total number of reference marks and to bring only this selected subset of reference marks into operation. This selection takes place through the allocation of a light source or a reflecting element to each of the selected reference marks. The scanning unit operates to generate two square wave scanning signals, a reference signal in response to the reference marks and a selection signal in response to the presence or absence of the light source or the reflecting element associated with the selected reference marks. A logic circuit is provided which is responsive to the reference signals and to the selection signals such that a control signal is generated by the logic circuit only if both the reference signal and the selection signal are present simultaneously. The light sources or reflecting elements which serve to designate the selected reference marks can arbitrarily be moved as necessary such that the selected subset of reference marks can be freely and arbitrarily chosen from the total number of reference marks readily and without alteration of the scale itself.

Abstract: The input protection circuit protects a MIS transistor Q 0  from high voltages. Resistors R 1  and R 2  are connected in series between an input terminal in and the gate of the transistor Q o . A first protection transistor is connected between a point N1, where R 1  and R 2  are joined, and a ground power supply line V ss . A second protection transistor is connected between a point N2, where the resistor R 2  and the gate of transistor 0 0  are connected, and the high power supply line V cc . 
     The second protection transistor Q 2  has a break-down voltage lower than the breakdown voltage of the MIS transistor Q 0  but has a high impedance when it is turned ON when a high voltage is applied to the input terminal in. The first protection transistor Q 1  has a breakdown voltage higher than that of the transistor Q o  but has a low impedance when turned ON when a high voltage is applied to the input terminal in. 
     The combination of protection transistor Q, and Q 2  provides adequate protection for the transistor Q o  even when it has only a minute and very thin gate insulating film.

Abstract: An axisymmetrical projectile having a specified design launch condition includes an axisymmetrical cavity 12 substantially filled with liquid, the cavity dimensions and liquid characteristics being so tuned that a main natural frequency of the liquid within the cavity approaches a nutation frequency of the projectile to cause resonance after a predetermined duration of flight following a design launch. The resonance increases the nutation amplitude causing a rapid rise in drag which quickly halts the projectile's flight.

Abstract: Molten aluminum or other metals are purified by contacting with a fluorocarbon, such as CCI<sub>Z</sub>F<sub>2</sub>, in order to decrease the amount of impurity metal elements along with gas and inclusions therein preferably in the presence of an agitator to enhance efficiency. An oxidizer, such as oxygen. is employed to prevent the carbon in the fluorocarbon from forming carbide inclusions. Oxidizing the carbon to carbon monoxide is preferred in treating aluminum since the monoxide effectively removes the carbon from the system without oxidizing aluminum. Preferably, a fluorine acceptor is employed to temporarily combine with the fluorine in the fluorocarbon and prevent it from reacting with carbon such that the fluoride is still available to treat the molten metal. The gases employed to treat the molten metal can be passed over a bed of carbon immediately prior to introduction into the melt. The system operates with low skim generation and without providing a salt cover and is capable of substantially fume-free operation.

The processor has a plurality of execution units 24, 26, 28, 30, with each execution unit executing a different set of instructions of the instruction repertoire of the processor. The execution units execute instructions issued to them in order of issuance by the pipeline 12 and in parallel. As instructions are issued to the execution units, the operation code identifying each instruction is also issued in program order to an instruction execution queue 18 of the collector. The results of the execution of each instruction by an execution unit are stored in a result stack 38, 40, 42, 44 associated with each execution unit. Collector control 46 causes the results of the execution of instructions to program visible registers to be stored in a master safe store register 48 in program order which is determined by the order of instructions stored in the instruction execution stack on a first-in, first-out basis. The collector also issues write commands to write results of the execution of instructions into memory in program order via a store stack 50.

Abstract: @ Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method and apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "signature" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.
