Abstract: A male and female electrical connector are held together via a permanent magnet inside the female connector. The male connector is generally spherical and of ferrometallic construction so as to be attracted by the permanent magnet. A number of male connectors may be attached to a multi-conductor cable, each male connector being electrically connected to only one of the conductors. In this manner, a multitude of electrical connections can be made concurrently. The invention is especially suitable for use in medical applications requiring an electrical attachment to be made to a patient which may be easily disconnected by the patient when he so desires.

Abstract: A distributed collector ballast resistor structure for use in a distributed collector contacted transistor comprises a diffusion geometry which is designed to employ a number of distributed collector ballast resistors in parallel as opposed to a single bulk resistor in series with the collector circuit thereby generating a lower current for a given voltage during avalanche while allowing lower saturation voltage, better RF gain and higher saturated output power.

Abstract: Flat and parallel depositions of low pressure chemical vapor deposited (LPCVD) polycrystalline intrinsic silicon are formed on both sides of a wafer of P-I-N <100> V-grooved substrate of silicon to support the wafer during subsequent polish removal from the top surface. This structurally reinforces the crystal wafer and helps prevent warpage and cracking during subsequent handling.

Abstract: An improved method for forming a metal-silica coating solution having particular utility in the formation of metal-organo-silicate films on semiconductor surfaces is disclosed. The method comprises the steps of forming a mixture of a first solution having a metal salt and a cross-linking agent dissolved therein and a second solution having an organo-silicate dissolved therein, and aging the mixture a predetermined length of time. This mixture can then be applied to the semiconductor surface where cross-linking takes place such that a viable film is formed. Further heating of the semi-conductor device causes a metal film to be formed which is in turn diffused into the semiconductor device. By the use of the metal-silica solution, an improved method for diffusing metal atoms into silicon for lifetime control is achieved.

Abstract: In a word processor having a video screen capable of displaying only a portion, typically one-third, of a full page of text stored in a memory, a display advance system causes the screen to display the next one-third text section upon actuation of a control key. This is accomplished by (a) ascertaining from the location of a displayed cursor the identity of the next sequential text section and the initial address of the memory area storing that next section, and (b) generating the video display using text from that memory area, beginning at the next video frame.

Abstract: An electronic system for reducing a full page of text to fit onto the visual display screen of a partial page display word processing device for purposes of reviewing the format and page layout of the text. The text is not always legible in this condensed mode, which is switch selectable by the operator, but while in this mode the text may be edited and manipulated in the normal manner provided by the controls of the word processing device. The system utilizes both electronic digital logic and analog circuits to condense the size of an entire page of text by approximately a factor of three. The digital logic selects and displays only five of the normal fourteen horizontal lines of dots comprising each row of characters within the page of text to be reduced, thus condensing the characters vertically.

Abstract: A system for recording and retrieval of data consisting of a data storage means having a pre-recorded signal imposed thereon, data recording and playback means, and a control means. The control means is coupled to the recording and playback means so that it receives the pre-recorded signal and controls the rate at which data is recorded on and recovered from the data storage means with respect to the pre-recorded signal.

Abstract: A data transfer terminal of the type including a keyboard means, a display means and a printer for use in a data center controlled data transfer system. The printer of the data transfer terminal is provided with a library phrase memory. The library phrase memory contains a plurality of predetermined, commonly used phrases at various predetermined addresses in the library phrase memory. The addresses of the phrases correspond to codes which are included in messages sent by the data center to the data transfer terminal whereby the length of the messages from the data center to be printed by the printer of the data transfer terminal is greatly reduced.

Abstract: A print element for use in high speed printing machines, having a plurality of metallic print characters which are substantially flat and are flexible. The characters are struck by a hammer surface which is curved so as to conform to the curvature of the platen upon which the characters strike. The characters are struck by the curved hammer surface and thereby temporarily deformed to conform to the curvature of the platen, thus producing a character of uniform density on the printing surface.

Abstract: An artificial fireplace log is formed with a groove in its surface extending axially along the length of the log. The log is provided with a paper wrapper having a flap, located near the upper limit of the groove, which flap extends outwardly from the log such that the flap can be easily ignited. On the inside surface of the paper wrapper directly opposite the location of the groove is placed a combustible material. This material extends along the length of the log and is of a width less than the width of the groove. By reason of the placement of the flap, groove and combustible material, the combustible material is easily ignited which in turn causes the log to become uniformly lighted over its length in a very short time.

Abstract: A gas filled, balloon-like object capable of defining a non-spherical shape, such as a lenticular shape, suitable as a decorative object for home use or the like. A high modulus graphite-impregnated epoxy material is used to prevent distortion of the inflated object.
