Patent JP-S60226092-A (JP)
Title: Sense amplifier
Inventor: SHINDOU TAKESHI
IPC: H03F3/345
Filed: 1984-04-25
Abstract: PURPOSE:To realize a CMOSRAM which has increased a read-out operating speed by connecting in common the gate of an MOS transistor of the current source of a single end type differential amplifier and the gate of an MOS transistor connected to the output terminal of its differential amplifier. CONSTITUTION:In case a control terminal RE and bit lines BL, -BL are ''H'', each corresponding terminal potential of MOSTs (Q4, Q1), (Q5, Q2) becomes equal, and a current flowing through an nMOSTQ1 becomes equal to a current flowing through an nMOSTQ2. At present, when the bit line -BL starts to drop to ''L'' from this state, the current flowing through the nMOSTQ1 decreases, but the current flowing through the nMOSTQ2 increases by a decreased portion of the current flowing through the nMOSTQ1, by a constant-current source constituted of an nMOSTQ3. As the current flowing through the nMOSTQ2 increases, the potential of a nodal point N2 drops due to a voltage drop by a pMOSTQ5. When the potential of the nodal point N2 drops, a resistance of a pMOSTQ4 decreases, and also, the current flowing through the nMOSTQ1 decreases, therefore, a voltage drop by the pMOSTQ4 becomes small, and the potential of an output terminal OUT rises.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of collision and hook-on of a coil spring with elastic deformation thereof by forming a device of a fitting seat, a coil spring and a buffer body, and threading a screw shaft of the fitting seat with one end of the coil spring, and threading a screw shaft of the buffer body with the other end of the coil spring. SOLUTION: A fitting seat 20 is fitted to a vertical wall 2 by providing a screw shaft 22 at a central part of a surface of a fitting plate 21, and inserting a fitting screw 23 into a screw hole 21a. A coil spring 30 is formed by spirally and tightly winding a spring wire. At this stage, rigidity is obtained by applying the pressure in the axial direction, and deflection is generated by applying the pressure in the deviating direction. On the other hand, a buffer body 40 is formed by connecting a screw shaft 42 to an elastic body 41. The whole length of the coil spring 30 is formed longer than a sum of the length of both the screw shafts 22, 42 so as to form a hollow part at a central part. In this condition, when a door 3 is opened, the impact is relaxed by the elasticity of the elastic body 41.  At this stage, the axial force is applied to the spring 30, but this axial force is transmitted to the vertical wall 2 through the fitting seat 20. With this structure, walking is not hindered, and while generation of damage can be prevented at the time of moving a furniture.
