Abstract: An apparatus 10 is employed for interfacing a telephone handset 18 to a telephone network. Typically, a telephone handset has one of a variety of different microphones disposed therein, such as carbon, electret, etc., where each type of microphone has a different output level and impedance. Conversely, the telephone network with which the microphone is to be interfaced has a preselected input impedance and signal requirement intended to match only one type of microphone. The apparatus 10 includes a plurality of switches 82, 84, 86, 88 and resistors 90, 92, 94 that are manually switchable into the circuit either separately or in combination to match the output impedance and signal level of the microphone with the input impedance and signal level of the telephone network. Alternatively, in a second embodiment of the instant apparatus, a variable resistor is employed to match the output impedance and signal level of the microphone with the input impedance and signal level of the telephone network.

Abstract: An electrically programmable antifuse element incorporates a composite interlayer of dielectric material and amorphous silicon interposed between two electrodes. The lower electrode may be formed from a refractory metal such as tungsten. Preferably, a thin layer of titanium is deposited over the tungsten layer and its surface is then oxidized to form a thin layer of titanium oxide which serves as the dielectric material of the composite dielectric/amorphous silicon interlayer. A layer of amorphous silicon is then deposited on top of the titanium oxide dielectric to complete the formation of the composite interlayer. A topmost layer of a refractory metal such as tungsten is then applied over the amorphous silicon to form the topmost electrode of the antifuse.

Abstract: 5 n7 An apparatus for discriminating information signals from noise signals within a communication signal. The preferred embodiment comprises a first signal level detector, a second signal level detector, and a comparing circuit. Each of the signal level detectors comprises a digital low pass filter which employs a comparator for comparing current signal samples with previous samples and generating a representative comparator output. Each low pass filter has an attack time and a decay time, each of which characteristics is determined by an operational coefficient, the coefficient being responsive to the comparator output. The first signal level detector receives the communications signal as an input and generates a detection signal as an output; the second signal level detector receives the detection signal as an input and generates a noise detection signal as an output. The comparing circuit compares the detection signal and the noise detection signal and produces a speech burst detection signal. The operational coefficient is valued in the first signal level detector to establish a fast attack time and a slow decay time, and the coefficient is valued in the second signal level detector to establish a slow attack time and a fast decay time.

Abstract: The editing apparatus and method uses an automatic search function of the starting and ending points of a program to be edited. The editing apparatus includes a key input (10), an edit adjuster (30), a playback system, a recording system, a display (110) and a system controller (20). The edit adjuster (30) controls editing operation to allow a playback signal within a preset editing section output from the playback system to be recorded on the recording system in accordance with the output signal of the key input (10). The editing method is performed by first editing step of setting starting and ending points on at least one editing sections on a recording medium in the playback driver, and controlling the editing operation by the detecting of the starting and ending points marking information on the editing section which is randomly set from points between the initial point and the final point of the recording medium. The second editing step selects one editing section from at least one set on the recording medium, and editing by detecting the starting and ending points of the set editing section. Therefore, a desired editing section can be randomly designated. Then, editing is controlled by detecting the designated information, thereby enabling a video tape duplicating system to precisely edit various programs.

Abstract: In a mold apparatus, the receiving molding surface and the opposing molding surface are each mounted coaxially and in sliding fashion within an alignment means. Both of these alignment means have an equal number of spaced apart alignment pads which are positioned such that opposing pads will be in cooperable engagement with each other during pressing. 
     Utilizing the disclosed apparatus, a method for molding precisely shaped articles, such as magnetic memory disc substrates which require precisely parallel, opposite molded surfaces, is described. Simply stated, the method utilizes the alignment pads' thermal expansion characteristics to induce a controlled level of thermal distortion to obtain pad lengths which result in parallel opposing molding surfaces. There are two means for accomplishing this pad length required for parallel molding surfaces: the first method, controlled heating, consists of introducing heat to a pad to cause it to expand, thereby extending the length thereof; the second method, controlled cooling, consists of introducing cooling to a pad to cause it to contract, thereby shortening the length thereof. 
     Once pad lengths are adjusted and thus the molding surfaces are parallel, the glass article may be pressed. This method is suitable for press molding any glass article which requires parallel opposing surfaces, regardless of the article's thickness.

Abstract: In a gas-blast circuit breaker, compressed gas is passed through the moving contact piece (28) into the arcing space (40). Said arcing space (40) is bounded by the cylinder (58) and the piston (60) which is moved with the moving contact piece (28). The piston (60) has inlet openings (70) which are closed by means of the valve body (72), such that they can be opened. The operating device (76) is supported on the neck (64) of the piston (60) so that said operating device (76) can be displaced in a reciprocating manner between two latching positions. During switching on, the tab (84) of the operating device (76) strikes against the stop surface (98), as a result of which the operating device (76) is moved into the first latching position (76'). At the same time, the valve body (72) is moved into the closed position (72'). Towards the end of the switching-off movement, the shaft (86) runs onto a stop (96) so that the operating device (76) is moved back into the upper second latching position, as a result of which the valve body (72) is moved into the open position and is held. During switching on, the arcing space (40) is thus connected to the surrounding space (94), and is separated from it again before the start of switching off. The drive is supported when switching off large currents and no more work is demanded of it during switching on and when switching off small currents. The gas-blast circuit breaker thus manages with a low power drive. <IMAGE>
