Title: Vertical synchronizing signal separation circuit
Inventor: CHIBA MASAHIKO
IPC: H04N5/10
Filed: 1990-02-22
Abstract: PURPOSE:To stably perform the separation of a vertical synchronizing signal by employing such configuration that an integral capacitor is charged/discharged simultaneously, and an electric charge is charged to or discharged from the capacitor based on current difference between charge and discharge. CONSTITUTION:The electric charge is accumulated in the capacitor Co by a current IA when the base potential of a transistor Q1 is high, and it is discharged from the capacitor Co by a current IB when the base potential of the transistor Q1 is low. The current for the charge/discharge of the capacitor Co can be decided by setting respective resistance ratio of resistors R3, R7, and R8, R11, and also, the current difference between the charge/discharge can be easily reduced. Also, since the fluctuation of differential currents IA and IB can be suppressed even when dispersion exists in a reference current Ir, the hFE of the transistor, etc., stability for the dispersion can be obtained, and the capacity of the capacitor Co can be reduced, and the incorporation of the capacitor Co in an IC in a stable operating state can be realized.

Title: Position adjusting member and position adjusting method
Inventor: YAMAMOTO TATSUSHI
IPC: G11B5/53
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of input head required for position adjustment by pressing a wedge-shaped tool onto the surface of a shape memorized shape memory alloy and performing plastic deformation accordingly. SOLUTION: The position adjusting member 1 is plastically deformed by pressing the tool 4 having a wedge-shape at the tip onto the surface of the shape memory alloy 2 memorized once to be flat and increasing contact pressure of the wedge-shaped tool 4 under the state of holding the back surface pressed by this wedge-shaped tool 4 by means of a high rigid and flat surface. Thus, by driving the wedge-shaped tool 4 into the shape memory alloy 2, the alloy 2 is plastically deformed from its flat shape to such a shape warped to the side worked by the wedge-shaped tool 4 as a whole. Consequently, a plastic deformation area 3 is concentrated only in the vicinity of an area caved by the tool 4. Therefore, when one side surface is only heated at the time of position adjustment by using this member 1, the whole area 3 can thus be heated.
