Abstract: DATA INTERFACE MECHANISM FOR INTERFACING       BIT -PARALLEL DATA BUSES OF DIFFERENT BIT WIDTH                         Abstract A data interface mechanism for interfacing bit-parallel data buses of different bit widths. This mechanism provides an automatic and efficient mechanism for converting data bytes into plural-byte data words and vice versa.  The mechanism utilizes a plurality of random access (RAM) storage units located between the two data buses and an addressing structure wherein the higher order address bits are supplied to a chip select decoder to produce different chip select signals which are used to select different ones of the RAM units.  For successive data transfers to or from the narrower data bus, storage addresses are used which produce different chip select signals which select the different RAM units one after the other in a sequence which repeats itself.  Thus, successive data bytes to (from) the narrower bus are transferred from (to) the different RAM units in a rotating manner. For data transfers to or from the wider data bus, a storage address is used which produces a distinctive chip select signal which is different from those used for the individual narrower transfers.  This distinctive chip select signal causes the storage control logic to simultaneously select all of the RAM units.  This enables a simultaneous parallel transfer of data from all of the RAM units to the wider data bus or vice versa.

Abstract: CIRCUIT FOR MODIFYING THE IF RESPONSE OF A                  TELEVISION RECEIVER               ABSTRACT OF THE DISCLOSURE           A "walking circuit" for modifying the IF frequency response of a television receiver is disclosed.  The walk-ing circuit includes an amplifier having a pair of select-able gain-degeneration impedances, one such impedance pro-viding the amplifier with a wide band frequency response and the other providing the amplifier with a frequency sensitive response whose peak is centered at the IF fre-quency of the picture carrier.  A current-steering circuit, responsive to the level of the signal received by the receiver, selects the wide band degeneration impedance by steering current through it when high level signals are received so that the amplifier does not modify the IF frequency response.  When low level signals are received, current is steered through the frequency sensitive degeneration impedance for modifying the IF frequency response such that maximum gain occurs at or near the IF frequency of the picture carrier.

Abstract: ABSTRACT      TITLE:  Temperature control for cooking appliances This invention relates to a temperature control for cooking appliances having a single heating chamber wherein cooking is accomplished by heating with high-frequency energy and heating by elevating the temperature of air in the heating chamber with a heater, which ac-complishes a control of temperature through the use of two or more temperature sensors having dissimilar tem-perature characteristics and dissimilar usable temperature ranges in combination with a microcomputer.  The output voltage from the reference voltage generator is compared with temperature signal voltages from the above two or more temperature sensors and the results are processed by the microcomputer so as to effect an automatic cooking and, at the same time, to judge the presence or absence of the temperature sensor probe in food or the presence or absence of a trouble.  The above arrangement simplifies the control circuitry, decreases the number of parts required, and improves the safety and reliability of the control system.

C. board bobbin and electrical component assembly or construction consisting of a cylindrical body of molded plastic substance which is adapted to mount one or more coils, and optionally to receive in its bore a reed switch capsule. One end of the body has an apertured wall to receive an eyelet by means of which the body can be readily mounted on end, on the board. As a separate piece, a terminal retainer sleeve can be fitted over an end portion of the body, such sleeve having at least one pair of aligned notches in its ends and at least one internal groove which is aligned with and connects to said notches. At least one terminal wire having a U-shaped portion is disposed in said groove and notches, said cylindrical body retaining the terminal wire in its operative position, and the wire having a projecting end portion adapted to extend through the hole in the P. C. board to effect connections thereto.          The advantage of this construction over the devices of the prior art is that less time is required in assembly, and the arrangement is such that it lends itself to installation in a P. C. board by means of automatic or semi-automatic equipment. Accordingly, the manufacturing cost is kept as low as possible.
