Abstract: Printed circuit board electronic assemblies (76) having improved thermal dissipation capabilities are obtained by adding electrically insulating but thermally conductive heat shunt components (80-85,90) to the circuit board (56) along with the regular electronic components (14-23). The heat shunt components (80-85,90) have a shape so that they may be placed on the printed circuit boards by the same assembly equipment used for the other electronic components (14-23). 
     A typical heat shunt (80,90) component is a small parallelepiped of a highly thermally conducting electrically insulating dielectric (92), such as for example, alumina, beryllia, sapphire or aluminum nitride. It desirably has spaced-apart metal attachment lands (94,96) on one face (95) and an optional continuous metal layer (98) on the opposite face (97). 
     In a typical application, one end (94) is soldered to the contact pad (66,68) where a power dissipating component (12) is also attached, and the other end (96) is soldered to a nearby ground lead (26′).

Abstract: Low noise circuits for single stage and multi-stage circuits reduce power rail noise, including both ground noise and supply noise caused by output power rail ground lead and supply lead inductance. Anti-bounce circuits reduce ground bounce by suppressing turn on of the output stage pulldown transistor element during transient occurrence of ground bounce events. Similarly anti-droop circuits reduce output supply V CC  droop by suppressing turn on of the output stage pulldown transistor element during transient occurrence of V CC  droop events. Anti-undershoot circuits dissipate ground undershoot energy by establishing a transient sacrificial current flow through the parasitic output ground tank circuit following transition from high to low potential at the output and by prolonging the sacrificial current flow during transient occurrence of ground undershoot events. Similarly anti-overshoot circuits dissipate overshoot energy in the parasitic output supply tank circuit by establishing a sacrificial current flow during transient occurrence of V CC  overshoot events. Ground noise and power noise detectors are used for detecting occurrence of bounce, droop, undershoot and overshoot for actuating and enhancing operation of the low noise circuits. The power rail noise detectors and anti-­noise circuits are combined in various combinations and permutations.

Abstract: A novel semiconductor memory device having address comparator (2), word line drive cirucit (4) sense circuit (6), and control circuit (3) is disclosed. The comparator (2) judges whether or not a row adress read in the present access cycle is in correspondance with that in the last cycle Where it is judged that the former is not in correspondence with the latter, the control circuit (3) allows the sense circuit (6) to select a word line by this row address to transfer data of a memory cell to the bit line to allow the sense means to sense. On the other hand, where it is judged by the comparator (2) that the former is in correspondence with the latter, since data of the memory cell belonging to the same word line is already sensed in the last cycle, the control circuit (3) allows the readout circuit to read out data from a bit line corresponding to the column address without causing the sense circuit to carry out a sense operation for a second time. Thus, only when the row address changes with respect to that in the last cycle, a sense operation is caused to be carried out. Thus, the readout operation can be performed at a high speed.

Abstract: A tracking control circuit of a rotary head tape magnetic recording and reproducing apparatus. The tracking control circuit generates (16) sampling pulses of first and second pilot signals for tracking based on a synchronization signal for tracking on a recording track, detects (12) an envelope signal from the reproduction signal reproduced by the magnetic heads (22A, 22B) which is amplified with a predetermined gain, detects (47) tracking error data from first and second pilot data obtained by sampling the envelope signal with the sampling pulses, detects (48, 55) reproduction level error data, controls (19C) the feeding speed of the magnetic tape based on the tracking error data, and controls (57, 58) the amplifying gain of the reproduction signal based on the reproduction level error data. As a result, deviations of reproduction levels of the magnetic heads (22A, 22B) are effectively corrected, and tracking control of the magnetic heads on the recording tracks is extremely precise.

Abstract: A switch machine operates a track switch under radio control via a switch controller. The switch controller may be given an identifying address unique to it which distinguishes the switch machine from other switch machines in the railway territory. In addressing or programming the switch machine, a portable terminal is used. The controller in enabled by a manually actuable switch to accept identifying addresses which is stored in electrically erasable programmable read-only memory (EEPROM). Whenever a message is received over the radio link, the identifying address is read out of memory. In order that the identifying address is vital (fail-safe) and to guard against any errors which change the identifying address and which can cause the controller to effectuate operation of the track switch in front of an oncoming train or when the train is over the switch, the address is stored in the EEPROM by encoding the identifying address into unique multi-bit check words. Whenever a request to read the address is received by the switch controller, an attempt is made to write check value words, the value of which is equal to the difference between the value of the unique check words and the check words. A check value word replaces a unique check word in the event of a failure in the EEPROM or its addressing logic. The check value is also read into a check word register. The content of the check word register and the location in EEPROM for the check word under test is read into exclusive or gates. If there is a failure, the output of the array is a word having a value of zero, whereas if there was no failure the result of the exclusive or operation will be a word having the value of the check word. These check words are used in providing a vital output message for controlling the track switch and to provide and acknowledge message for transmission over the radio link to the central office or locomotive which communicates with the railway track switch controller. The switch is powered only when a vital output representing a desired switch operation (throwing the switch to normal to reverse or vice versa) is called for over the radio link.
