When the Tr Q2 is turned off, a capacitor C2 is charged by a constant-voltage source 8, and a voltage VO1 rises. When the voltage VO1 is large by a comparator 9, a voltage VR1 rises, a voltage VQ1 falls, the Tr Q1 is turned off, and the Tr Q2 is turned on. When the Tr Q2 is turned on, the capacitor C2 is discharged. On the other hand, when a voltage VL1 is large by the comparator 9, the voltage VR1 falls. That is to say, by comparing the voltages VO1, VL1, the Tr VR1 which turns off the Tr Q1 is generated, and the OFF timing of the Tr Q1 is measured.

Filed: 1983-02-23
Abstract: PURPOSE:To improve transfer efficiency and to obtain the reliability of a system resulting from the exclusion of a bus common part by transferring data onto a common bus only when the data is written in a buffer memory from a processor. CONSTITUTION:When a CPU1 writes data in the buffer memory 21, a writing detector 22 detects that and outputs a writing detection signal 40 to a write address memory 23 and an occupation controller 30. When the common bus 10 can be occupied, a transfer-ready signal 42 is sent to a data transfer device 27. The transfer device 27 reads data out of the memory 21 and transfers it to the common bus 10. An input/output device PIO driver 50 receives it and writes it in a PIO1 through a bus 11. Further, a data receiver 28 receives the data transferred to the common bus 10 and writes it in the buffer memory 21. Therefore, the CPU1 reads the data out of the buffer memory 21 to obtain data transferred from a CPU2 or PIOs 1-4.

IPC: H01L21/822
Filed: 1983-02-22
Abstract: PURPOSE:To optimize the delay time of signal propagation between elements by a method wherein weight is given to a signal line between the elements, the products of length and weight of all the signal lines are obtained, and then the arrangement of the elements on a circuit substrate is determined in such a way that the sum of these products become the minimum. CONSTITUTION:Weight is given to the signal line between the elements, the products of length and weight of all the signal lines is obtained, and then the arrangement of the elements on the circuit substrate is determined so that the sum of these products becomes the minimum. For example, wiring pattern lengths are decided as l1, l2,...ln by combining the elements, and the rate of signal urgency on each signal line is divided into three steps. Weighting FA, FB, and FC for the delay time of signal propagation is decided as e.g. FA=8, FB=4, and FC=1, where FA is a rate necessitating the minimization of the delay time, FB a rate sufficient at a normal time, and FC a rate sufficient at a late time. Then, wiring route between the elements is determined so that the value L in an evaluation formula L=FA.l1+FB.l2+FC.l3+...+ FB.ln becomes the minimum.

Filed: 1980-03-06
Abstract: PURPOSE:To prevent the occurrence of a logically unstable condition of a dynamic circuit by changing over a current source of a dynamic circuit of an electronic timepiece to a capacity arranged in parallel with a battery when a lamp is lighted. CONSTITUTION:When the lamp 206 is lighted by closing a switch 208 during a given time, an N channel transistor 203 is turned off through a clock formation circuit 204, and a current source of a dynamic circuit 202 is changed from the battery 207 to the capacitor 201 arranged in parallel.

Accordingly, even if th battery voltage is changed by a large current at the time of lighting, there exists no influence. Therefore, the occurrence of a logically unstable condition of the dynamic circuit can be prevented.

Title: Cap shaped parts arranging and transporting device in vibrating type parts supply machine
Inventor: ARAIDA TOMOJI
IPC: B65G27/02
Filed: 1982-02-24
Abstract: PURPOSE:To discharge parts that have a concave portion at the bottom to the outside in the direction of diameter of a cup shaped vessel by forming the wall section of a track in the direction of the vessel near the discharge end section and forming a plurality of grooves on the track. CONSTITUTION:A part (m) that was transferred with its concave portion 1a facing upwards passes as it is the transfer face 12a and proceeds to the discharge end of a track in the direction of an arrow mark C, but the part (m) with its concave portion downwards has its periphery wall 1b engaged in a groove (e) and drops into the discharge passage 17. Since a twisting vibration force B is a circular vibraing force, it receives centrifugal force in the direction of diameter of a ball. Consequently the part (m) receives on the transfer face 12a a force that points to the outside of the diameter direction of the ball. A part (m) drops at once, therefore, into the discharge passage 17, when it is transferred with its concave portion 1a facing downwards.

Abstract: PURPOSE:To prevent mixing-in of common mode noise by dispensing with a transformer by constructing an initial-stage amplifier circuit of a differential amplifier circuit, and by connecting this circuit directly to a DC-driven type superconducting quantum interference device(DC-SQUID). CONSTITUTION:When DC-SQUID 4 is put in an active state by a prescribed current made to flow by a bias current circuit 8, a magnetic flux in linkage with the SQUID 4 is modulated by a signal for modulation given to a feedback modulation coil, 5 from a rectangular wave oscillator circuit 11 and it appears as a modulating signal at the opposite ends of the SQUID 4. This modulating signal is amplified by a differential amplifier circuit 15 and detected in a phase detection circuit 9 by using a reference signal from the circuit 11, and a feedback signal corresponding to an output of the circuit 9 is given to the coil 5 from an integrating circuit 10. Since this feedback signal so changes as to compensate a change in the magnetic flux being in linkage with the SQUID 4, the magnetic flux can be measured by reading out the change of the signal.
