Inventor: MATCOVICH THOMAS JAMES
IPC: H01L21/603
Filed: 1979-04-06
Abstract: The tool 10 for thermosonic attachment of fine wire leads to terminal pads of semiconductor devices is mounted in a holder 11 which conveys ultrasonic vibrations to the tool. For heating the working tip 24 of the tool a resistive-film heater 23 is applied to a frusto-conical surface of the tool. Terminal pads 2 2  for the heater 23 are resiliently engaged by ends 19 of leads 17, which can be separated, for replacement of the tool, by means of a cam 18. The resistive film heater, which may take various forms and be used with insulating layers covering an electrically-conductive tool, with covering layers of low emissivity and with terminal pads of various forms, offers advantages of ease of manufacture, reliability, low mass, and control of temperature by monitoring changes of resistance.

Abstract: For the purpose of the unique spatial splitting of an optical frequency mixture into a multiplicity of very narrow frequency ranges, two dispersive elements (transmission gratings, reflection gratings, interferometers are arranged behind one another in the beam path in such a way that they generate diffraction patterns in two mutually perpendicular directions, and that a very high order of diffraction (eg. N = 100...1,000) is incident in the beam path from the first dispersive element (35) and a lower order of diffraction (eg. M = 1...10) from the second diffraction element (34). The high spectral resolution of this arrangement permits a multiplicity of applications: frequency multiplex data transmission via optical fibres, three- dimensional television, high-speed image recording, real-time spectral apparatus. In optical data transmission via optical fibres, the spatial position of the picture points (plane 32) to be transmitted is frequency-coded using a spectral apparatus (300) of the type mentioned and reconstructed after transmission by the optical fibre by means of a second spectral apparatus (300') in a picture plane (39). <IMAGE>

Abstract: The I/O device control subsystem controls issuance of commands to one I/O device (100) while it is doing data transfers with another I/O device (150). The time required to write the transferred data, known at the time the data transfer command is issued, is added to the current time. Then, when a command is issued to the first I/0 device (100) while the other I/O device (150) is writing the transferred data, the time required for executing that command is determined as well as the time remaining for completion of the write operation and if the time required for execution of the new command is less than the remaining time, the new command is allowed to be executed.

Abstract: A privacy communication method is performed by transmission of a signal from a transmitter (1) to a receiver (7) with the signal kept in a privacy state. To that end, an input signal is alternately subjected to compression and expand ion in terms of the time base by means of a time base compressing/expanding circuit (3), whereupon the signal is transmitted from a transmitting circuit (5) through a transmitting antenna (6). The transmitted signal is received through a receiving antenna (8) by a receiving circuit (9) and is then alternately subjected to expansion and compression in terms of the time base of the received signal by means of a time base expanding/compressing circuit (10) in synchronism with the compression and expansion on the part of the transmitter, whereby the original signal is restored.

Abstract: By using water-repellent emulsions based on paraffin and/or polyorganosiloxanes in the preprinted resist it is possible to effect the preparation of white and coloured discharge resist effects on differently coloured grounds on synthetic fibre textile sheet materials with alkali-dischargeable disperse dyes by the energy-saving wet-on-wet technique. The novel process can also be used with advantage on polyester and cellulose or wool blend fabrics, in which case the diversity of design options can be increased still further by including reactive dyes. In addition, the crispness of the prints is significantly improved when, after the resists have been applied, the water-repellent emulsion is destroyed by adding sulphates or phosphates to the overprinting colour applied in the second phase.

Abstract: A method and system for monitoring operating state in the control of a robot for actuating a robot hand (1) in accordance with taught data to cause the hand (1) to grip a part (BT) and then service a mate (PB) with the part (BT) in a playback mode. The method includes a step of teaching an operating state by actuating the robot arm or hand in accordance with the taught data and storing in a memory information indicative of a reference state based on an output signal from sensing means (SA, SB) for sensing the state of an operation performed by the robot hand (1). The next step is to monitor the operating state of the robot hand (1) in the playback mode by comparing an output signal from the sensing means (SA, S8) with the reference state stored in the memory.

Abstract: An electrical shorting switch assembly for use with an electrolytic cell includes a plurality of parallel path electrical switches. One of the switches is an arching switch which is designed to be a last-to-open and last-to-close switch of the assembly. A common rotatable operating shaft is used to actuate opening and closing of the electrical switches. The arc switch has separate linking means between the arc switch and the shaft which permits sequental operation of the arc switch relative to the main current-carrying switch or switches. The arc switch linking means in conjunction with the linking means for the current switches determine that the arc switch is the last to open and last to close.

Abstract: A phase-locked loop having improved off-frequency detection. A variable frequency output signal (V sw ) is to be precisely locked to the frequency and phase of an alternating input signal. This is accomplished by alternately utilizing two feedback loops [Fig. 1 (V out , 14, 15)). A reference signal (V ref 1 ,), having a frequency approximately equal to the frequency of the input signal is input to an initialization feedback loop 14 in which it is mixed with the output signal. The Initialization loop produces a feedback signal for controlling a voltage controlled oscillator (12) which generates the output signal. An off-frequency detector (32) detects the frequency difference between the output signal and the reference signal. When this frequency difference decreases below a predetermined level, the off-frequency detector disables the initialization feedback loop and enables a primary feedback loop. In the primary feedback loop the phase of the output signal is compared (14) to the phase of the input signal, and the difference signal controls the voltage controlled oscillator in such a manner that the phase of the output signal tracks the phase of the input signal. With this scheme, the initialization loop, which has a wide bandwidth, is used to control the voltage controlled oscillator over a wide range of frequencies of the output signal (i.e., the initialization loop has a broad capture range). When the frequency of the output signal has been brought within the capture range of the primary loop, operation is switched to the primary loop. The primary loop has a narrower bandwidth and therefore provides better noise rejection than the Initialization loop.
