Title: Tape motion control for reel-to-reel drive
IPC: G11B15/43
Filed: 1978-05-18
Abstract: High tape acceleration rates are achieved in an unbuffered, capstanless tape drive system by a tape motion control apparatus employing separate drive motors for each reel of a reel-to-reel tape transport. Tape moves from one reel past a read/write head and a tape tension sensor to the other reel, there being no tachometer in the tape feed path. A tachometer on one reel shaft provides a large number of pulses per revolution which pulses are counted by a counter and a tachometer on the other reel shaft provides only one pulse per revolution, which pulse gates out the count then accumulated in the counter for actuating means to provide motor acceleration currents of a magnitude corresponding to said accumulated count according to a predetermined servo algorithm for controlling rotation of both reels. A tape radius constant corresponding to the actual length and thickness of tape in the system is calculated during initial wrap of tape onto the takeup reel. Tension is tightly controlled by an analog tension sensor and servo system.

Patent ES-484588-A1 (ES)
Title: Inert carrier gas heat treating control process
IPC: C23C8/06
Filed: 1979-09-28
Abstract: Ferrous articles are heat treated by introducing a gaseous carbon source and an inert carrier gas into a heat treating furnace containing the ferrous articles. The heat treating process is controlled by determining the amount of carbon monoxide resulting from reactions in the furnace and controlling the amount of inert carrier gas in the furnace in response to the amount of carbon monoxide in the furnace atmosphere to control the carbon potential to a desired level by minimizing the effect of equilibrium reactions. Best results are achieved when the amount of carbon monoxide is less than about 3%, preferably, less than about 1%, by volume. Controlling the carbon monoxide level will minimize the effect of harmful decarburizing agents (oxygen, carbon dioxide and water vapor). Under the reaction conditions existing within the furnace operated in accordance with the present invention, hydrocarbon dissociation reaction and primary carburizing reaction are nonequilibrium reactions and control the process results. Oxidation reactions, secondary carburizing reaction and hydrogen decarburizing reaction are equilibrium reactions but are minimized when the inert carrier gas level within the furnace is used to control the carbon monoxide level, especially less than about 3%, preferably less than about 1.0% by volume. Carburizing is a preferred heat treating process and can be carried out using a hydrocarbon source such as methane and an inert carrier gas such as nitrogen.

Patent ES-8308156-A1 (ES)
Title: Integrated circuit protection device
IPC: H03K17/08
Filed: 1982-03-24
Abstract: Disclosed is a protection circuit which may be used, for example, in a television receiver to protect circuitry formed within an integrated circuit from damage due to excessively high voltage transients. The protection circuit comprises a PNPN structure forming a silicon controlled rectifier (SCR) and metal-oxide-semiconductor (MOS) transistor integral to the SCR structure. The SCR and the MOS transistors are arranged to form a two terminal protection circuit which is rendered conductive when the potential difference across the two terminals is greater than a predetermined threshold. One terminal of the protection circuit is connected to an input or output signal terminal of the protected circuit, and the other terminal is connected to a reference terminal to which a reference potential such as ground potential is applied. Transient voltages appearing at the integrated circuit terminal greater than the predetermined threshold voltage causes the protection circuit to conduct current, thereby dissipating the energy of the high voltage transient and protecting the integrated circuit from damage. In one embodiment, the gate electrode of the MOS transistor is connected to the reference terminal, and in another to the signal terminal. The latter connection provides a much larger predetermined threshold than the former, and typically considerably in excess of the supply voltage.
