A semiconductor integrated logic circuit comprises a load transistor having a carrier injecting region and a carrier extracting region and an inverter transistor having a source region, drain regions, channel regions each connected between the source region and each of the drain regions, and gate regions defining the respective channel regions therebetween. The extracting region is merged into the...

A magnetic tape guide drum for a magnetic video recording and playback apparatus has a rotary magnetic head and is adapted for guiding a magnetic tape traveling spirally about the drum. The drum includes a rotary drum portion, a stationary drum portion and a shaft secured to the rotary drum portion and supported rotatably by the stationary drum portion for rotating the rotary drum portion. A groun...

PURPOSE:To improve operatability in an engine ever so better, by judging the frequency of starting and stopping in a car on the basis of an engine automatic starting-stopping discrimination signal out of a brake and so on, while making a device perform the control of automatic starting and stopping in the engine in an automated manner when the frequency comes so high. CONSTITUTION:During car drivi...

In a device for controlling the function of central lubrication installations with two electrically conducting components (8, 9) integrated into a signal circuit, a contact piston (18) provides the electrical contact between these components (8, 9). The contact piston (18) is guided with zero play in a bore (17) of one of the components (8, 9). It has a sealing section (19) which, in the working p...

Real time image zoom is obtained by sampling electrical signals corresponding to reflected ultrasonic waves at a sampling frequency whereby display data is obtained only in an area of interest. The sampling is delayed to eliminate signals from areas not of interest. Ultrasonic pulse repetition rate is selected so that internal resolution in the area of interest is optimized.

PURPOSE:To use effectively less input signal wires by arranging a titled device in such a way that input means by assignment of a number of copying sheet and detection of a copying condition are inputted by coupling with output signal wires under program control. CONSTITUTION:The key input from an operating part is taken into a CPU by the scanning signal from the output terminals R0-2, R9 of the C...

The present invention relates to an arrangement for the discrete-time adaptive on-off switching control of a continuous-time process with a binary switching actuator, which uses for the determination of the on-off actuating signal a prediction of a process output sequence over several future sampling intervals as reaction to a possible process input sequence that is applied to a discrete-time line...

This device comprises an asynchronous memory access control and permits the distribution of the access to a RAM memory (14) among a plurality of users (U1, U2, U3), the access being effected in an asynchronous manner. Certain users (U2, for example) can access the memory at adjacent addresses by means of a single row precharge cycle, the column access cycles (CAS) being successively effected durin...
