摘要： Microelectronic circuits are produced in semiconductor wafers with beam leads having adhering and non-adhering portions. The non-adhering portions comprise the projecting part of the beam lead. The wafer is divided into chips having beam leads by partially cutting the wafer from the reverse side with a laser beam. The wafer is initially positioned for the laser cutting using an infrared light and a vacuum for securing the wafer at the correct position prior to the laser scribing. The uncut portion of the wafer is broken and the semiconductor chips are separated. During the separation, the non-adhering portions of the beam leads become separated from adjacent chips.

摘要： Address decode logic is multiplexed for selectively decoding input address of a read-only memory (ROM) and a random-access memory (RAM) and for supplying the decoded addresses to the appropriate one of the memories. ROM and RAM input signal paths are controlled in alternate succession to alternately apply ROM and RAM address input signals to the decode logic. Output signal paths from the decode logic to both the ROM and the RAM are similarly controlled in alternate succession to supply decoded address signals to the appropriate one of the memories. The arrangement is implemented using field effect transistors.

摘要： A memory contains data in a plurality of discrete locations and is addressed at a rate that depends upon desired spacing between data from various locations as it is sequentially read from the memory. In a specific embodiment the data constitutes amplitude values of a complex wave form of a type produced by a musical instrument at equally spaced points in time along an axis of the wave form. The memory is addressed at any one of a plurality of rates selected in accordance with a musical note to be played. Selection of a particular note results in a repetitive read out from the memory of groups of amplitude samples that collectively represent a wave shape. The group repetition rate represents the frequency of the desired musical tone and is determined by a control number that is unique for each output frequency. The control number periodically increases a number stored in the memory address register by the value of the control number so as to identify appropriate data addresses in the memory. Having selected a unique control number and therefore a unique output signal frequency, the latter is modulated by changing the control number during the repetitive generation of groups of amplitude samples. The same magnitude of small change in the control number for a plurality of frequencies to be generated will achieve an ensemble effect for octave decoupling. A relatively small magnitude repetitive variation of the control number, as groups of amplitude samples are repetitively read from the memory, will provide a tremulant effect. Other types of variation of the control number will achieve other types of frequency modulation.

摘要： A sweep generator for a displaced-center sector-scan display of a radar system, in which the inductance of the cathode ray tube display device cooperates with a storage capacitor for directly generating a bipolar sweep current waveform utilized by the control yoke. A centering gate responsive to the radar timing, energizes the winding to start the sweep from a filter capacitor of the power supply. During a first polarity portion of the sweep the energized winding is storingly discharged into the capacitor and during the oppositely-polarized second portion of the sweep, a sweep gate allows discharge of the capacitor back into the winding. The winding energy is then discharged at the end of the sweep back into the filter capacitor of the power supply, whereby a very low-power source may be utilized for energizing the sweep generator.

摘要： A uni-directional spectrometer is described that can detect and distinguish between gamma ray and neutron fluxes. The scintillator has two parallel disposed cylindrical scintillating elements that are made, for example, of plastic. The plastic compound of one element comprises only protons or hydrogen atoms, having atomic weight one, and the other element is made of a chemically similar plastic compound comprising only deuterium or hydrogen atoms of atomic weight two. The two cylindrical scintillator elements are enclosed within an anti-coincidence or outer scintillator element, with both ends of each cylinder exposed. On the same adjacent ends of each cylindrical element are disposed photomultiplier tubes. On opposite sides of the outer scintillator element are disposed two additional photomultiplier tubes. The cylindrical elements and the outer element are each, respectively, enclosed in a thin coating of aluminum except where the respective elements are in contact with the photomultiplier tubes to isolate the light output from each element.

摘要： An electromagnetic deflection system to provide a low-cost, depressed-center CRT display for a sector scanning sensor. An auxiliary coil (usually a ring) is wound about a cathode ray tube, axially spaced intermediate the conventional deflection yoke and the display face of the CRT, and oriented relative to the longitudinal axis of the tube to provide a resultant magnetic vector which is mutually angled relative to such longitudinal axis. The deflection system can be driven by conventional low cost flyback deflection circuits producing sawtooth deflection currents. For example, in a display for an azimuthally scanning radar, the radar range sweep generator frequency output need be applied only to the vertical deflection winding of the conventional deflection yoke, while the radar azimuth scan frequency is applied either to the auxiliary coil alone or to the auxiliary coil and the horizontal deflection winding of the conventional deflection yoke in series.

摘要： A water washable dye penetrant composition for use in nondestructive testing of objects to locate voids and defects therein, containing an organic dye, preferably a fluorescent dye, a solvent for said dye, particularly an N-alkyl-2-pyrrolidone, e.g. N-methyl-2-pyrrolidone, and glycol monobutyl ether for thinning the dye penetrant solution substantially without changing any of its original functional characteristics, and particularly without affecting the sensitivity of the penetrant. In the method of application of the dye penetrant composition, such composition is applied to the surface of an object containing cracks and flaws, water is applied to the surface of the object, preferentially removing the glycol monobutyl ether vehicle or carrier, and momentarily leaving the remaining dye penetrant uniformly distributed on the surface, which is finally washed off the part, both the removal of the glycol ether component and the remaining dye penetrant occurring in the same washing operation. The part is then inspected under appropriate lighting conditions such as fluorescent or black light, to obtain colored traces from the dye penetrant remaining in the cracks and flaws.
