摘要： An integrated circuit AM radio receiver includes a scan-tuner comprised of a frequency synthesizer with micro-processor controller. The tuner stops scanning when an AGC derived signal increases beyond a predetermined level indicating a strong station and additionally when another signal falls below a predetermined level indicating that the radio is accurately tuned to the station frequency. The another signal is derived from an FM discriminator simultaneously using the same coil as is employed for tuning the last AM-IF stage.

摘要： A self regulating ceramic PTCR (positive temperature coefficient of resistance) heater has a pair of spaced interdigitated electrodes on one major surface of a ceramic PTCR plate. A heat transfer means is provided for extracting heat from the opposite major surface of the PTCR plate. Best heating efficiency is obtained when the thickness of the PTCR plate is about the same or is less than the average spacing between the electrodes.

摘要： A silicon integrated oscillator circuit is connected with a capacitor and produces a highly precise and stable triangular output voltage. Both the charge current and the discharge current are proportional to one reference current. A switching circuit terminates the charge and discharge intervals when the capacitor voltage reaches a level that is equal to intermediate points on first and second resistive-voltage-divider circuits, respectively. This is accomplished by a differential-transistor-pair comparator having the base of one transistor connected to a high voltage one of the reference points and a third transistor, which is connected collector to emitter across the one transistor, having a base connected to a low voltage one of the reference points.

摘要： In an integrated process for the anodization of aluminum foil for electrolytic capacitors including the formation of a hydrous oxide layer on the foil prior to anodization and stabilization of the foil in alkaline borax baths during anodization, the foil is electrochemically anodized in an aqueous solution of boric acid and 2 to 50 ppm phosphate having a pH of 4.0 to 6.0. The anodization is interrupted for stabilization by passing the foil through a bath containing the borax solution having a pH of 8.5 to 9.5 and a temperature above 80.degree. C. and then reanodizing the foil. The process is useful in anodizing foil to a voltage of up to 760 V.
