IPC: G06F9/32
Filed: 1986-04-04
Abstract: PURPOSE:To contrive to lower power consumption by stopping reading action at a machine cycle unnecessary to read a ROM based upon a control signal from an instruction decoder. CONSTITUTION:A data output signal 11 from a ROM 10 enters an instruction decoder 13 through an instruction register 12. The decoder 13 outputs a control signal 14 sent to respective parts of a microcomputer, and outputs the control signal to stop the action of the ROM 10 at the machine cycle unnecessary to read the data from the ROM 10, to a ROM control signal line 15. The control line and the clock pulse signal of a clock pulse line 16 are inputted to an 'or' circuit 17, is phase-inverted by an inverter 18 and inputted to a precharging signal line 6. The precharging signal comes to be a low level at the machine cycle unnecessary for reading, the charge of the bit line is not discharged and the power consumption is lowered.

Abstract: PURPOSE:To make it possible to detect the number of rotations of a rotary shaft at high resolution by continuously passing a rotor in the vicinity of magnetoresistance elements, and periodically bending the lines of magnetic force outputted from a magnetic force outputted from a magnet in the direction of the teeth of each rotor. CONSTITUTION:The lines of magnetic force emitted from a permanent magnet 3 are bent into the direction of a tooth 2' of a rotor 2a. At this time, the change in line of magnetic force in the direction of the Y axis acts on magnetoresistance elements 6A and 7A. Therefore the resistance values of the elements 6A and 7A are changed. By the same way, the change in line of magnetic force in the direction of the X axis acts on the elements 6A and 7A. Therefore, the resistance values of the elements 6A and 7A are changed. Then, the means for making the wavelength of the waveform of a continuously changing output voltage signal small and for substantially increasing the number of the teeth of the rotors 2a and 2b is provided. Therefore, even an electric signal which is changed with the rotations of the rotors 2a and 2b can be obtained at high resolution.

Title: Connection test system for circuit and terminal
Inventor: TAIKO NOBORU
IPC: H04L12/26
Filed: 1980-06-16
Abstract: PURPOSE:To test securely whether a terminating terminal is connectable, by sending a test signal from a data exchange to the terminating terminal repeatedly until a prescribed answer signal is sent back. CONSTITUTION:Once an originating terminal 1 originates, a central controller 22 sends a signal transmission command to a signal control circuit 23A. The signal control circuit 23A opens its gate only for a prescribed time T1 from a time t1 to send a test signal from a signal generator 24 to a data circuit 4. A terminating terminal 3, when connectable, sends an FSK signal to an aswer circuit 5. If the central controller 22 can not receive the FSK signal within the time T1 from the  time t1, a test signal is sent out again a time T2 later. Thus, the test signal is sent  out repeatedly within the prescribed limit time until the anwser signal is detected.
