A data processing system having a logic LSI, a plurality of memory LSIs and a circuit which eliminates delays in the time at which data read out form the memory LSIs reach the logic LSI. The circuit includes variable delay circuits for delaying the data signals read out of the memory LSIs. A control circuit start monitors the time when the data read out of the individual memory LSIs arrive at flip-flops which output the data to the logic LSI. The delay times in the variable delay circuits are controlled by the control circuit for the individual memory LSIs so that the times the data read out from the memory LSIs reach the logic LSI may coincide with a predetermined standard time. Thus, the read data from the individual memory LSIs are caused to reach the flip-flops simultaneously.

The present invention provides a clock signal supply method and system. A reference signal and a synchronizing signal are generated, as well as a clock signal, at a clock signal generating source end. Both the reference signal and the synchronizing signal have a period longer than that of the clock signal. The clock signal at a clock signal destination end is frequency divided in synchronism with the synchronizing signal to provide a sample to be compared with the reference signal. The resultant frequency-divided signal is compared with the reference signal in phase. A delay control is made for the clock signal in accordance with the result of the comparison to adjust the phase of the clock signal at the signal destinations.

The present invention relates to a clock signal supplying device provided with an automatic phase regulating function for preventing errors in the phase regulation due to noise. In the device according to the present invention, there is disposed a reference signal serving as a phase reference, and transmission lines for clock signals and a transmission line for the reference signal are disposed from a clock signal supplying source to devices which are destinations of the distribution of clock signals. The transmission line for the reference signal is adjusted in advance so as to produce no skew. In the device, which is the destination of distribution of the clock signal, there is disposed a variable delay circuit for regulation of the phase of the clock signal and a phase comparing circuit for comparing the output of the variable delay circuit with the phase of the reference signal to output the result of the comparison. In the device according to the present invention, a noise filter is provided which detects phase regulation errors to effect correct phase regulation. Furthermore, the phase regulation is effected while avoiding a period of time wherein noise is apt to be produced.

A laminated multilayer electric circuit is comprised of wafers having each internal electric circuits and laminated one after another. A signal transfer circuit used in the laminated multilayer electric circuit for transfer of signals between the wafers through an electrostatic capacitor has a receiving circuit of sufficiently high input resistance for receiving a signal from a capacitance electrode forming the electrostatic capacitor, and a circuit for clamping the level of the signal substantially within the input amplitude for the receiving circuit. The signal transfer circuit permits the signal transfer to be performed not through a flip-flop or the like and consequently at high speeds.

A magnetic sensor includes a housing in which flux producing means which comprises an electromagnet or a permanent magnet is received. A pair of magnetoelectric transducer elements are secured to a surface of the flux producing means which represents a magnetic pole, with a given spacing between the elements. In order to dispose the magnetoelectric transducer elements as close as possible to the outer surface of the housing, the latter is formed with a through opening at a corresponding position. The through opening is covered by a thin shield cap to protect the magnetoelectric transducer elements from a member being detected which is passed in sliding contact with or very close to the outer surface of the housing and to provide an enclosed construction for the housing.
