Title: Josephson sense circuit
Inventor: TAWARA SHUICHI
IPC: H01L39/22
Filed: 1987-03-20
Abstract: PURPOSE:To put a sense circuit in fast operation by absorbing a dynamic leak current by a Josephson junction when the gate current of a storage array consisting of plural storage cells including a sense gate circuit rises, and then preventing malfunction due to the absorption of a current and eliminating the need for an extra input signal with simple circuit constitution. CONSTITUTION:An AC current is supplied to the gate current supply line 4 of a Josephson sense circuit to supply a stationary current to the gate array 7 of storage cells including the sense gate circuit. In this state, signals are applied to input lines 5 and 6 for cell selection and switched according to information in a selected storage cell. Its gate current is transferred to the Josephson junction 1 through a 1st load resistance 2 to switch the junction 1, thereby absorbing the dynamic leak current at the time of the rising of the gate current. This gate current flows in a multi-input logic circuit 8 through a 2nd load resistance 3 to switch a circuit 8, thereby reading information out of the storage cell.

Title: Speed signal detector for motor
IPC: H02P6/06
Filed: 1992-03-23
Abstract: PURPOSE:To obtain a detection signal of average pole interval by combining a signal from a position detecting element constituting one rotor position detector with a signal from another position detecting element spaced apart mechanically by 180 deg. therefrom thereby producing a motor speed signal. CONSTITUTION:In a magnet 5 fixed to a rotor 4, narrow parts and wide parts of pole interval are distributed unevenly while being shifted by 180 deg. due to positional shift at the time of magnetization. Consequently, Hall elements E8, F20 spaced apart by 180 deg. produce waveform of pole distribution as shown by EE, FF. In other, when the Hall element E8 is detecting a narrow part T1, the Hall element F20 is detecting a wide part T2. Consequently, when the signals detected through the Hall elements E8, F20 are combined, T1 and T2 are averaged and a detection signal having constant pole interval T over the entire circumference of rotor can be obtained.

IPC: F02M51/06
Filed: 1979-05-25
Abstract: PURPOSE: To facilitate setting displacement of a movable core within a preset range, by making the position of a stationary core or a valve seat adjustable.
