Title: Magnetic recording and reproducing head having wear resistance and high permeability
Inventor: MASUMOTO RYO
IPC: G11B5/127
Filed: 1989-10-07
Abstract: PURPOSE:To obtain a magnetic head which facilitates forging and is superior in wear resistance and further, holds high saturation magnetic flux density and effective permeability by causing the magnetic head to be composed of Ni, Nb, and Ta holding specific weight ratios and an Fe holding a remained weight ratio as well as a small quantity of impurities; besides, by making its head consist of an alloy having a recrystallization aggregate structure that is indicated by an expression: {110}<112>+{311}<121>. CONSTITUTION:This magnetic head is composed of: 60-90wt.% Ni; 0.5-20wt.% for total amount of Nb and Ta (although Nb is 14wt.% or less and no Nb and Ta contain 0wt.%); a remainder wt.% of Fe; and a small quantity of impurities. Its effective permeability and saturation magnetic flux density are so high that its permeability per 1kHz is 3000 or above and the above flux density is 4000G or above. Further, its head consists of an alloy having wear resistance and high permeability which is equipped with a recrystallization aggregate structure indicated by an expression: {110}<112>+{311}<112>. For example, an ingot of the alloy having the above compositions is treated with forging or cold working to be formed into an appropriate shape and then is formed into objective shapes of thin film and the like. Subsequently, the materials are heated in a non-oxidizing atmosphere or in a vacuum at a temperature 900 deg.C or more and of melting point or less. The alloy having wear resistance and high permeability is thus obtained by cooling it at a temperature starting from a transformation point or higher of ordered lattice/not ordered lattice at an adequate speed corresponding to the composition of its alloy.

Filed: 1992-09-04
Abstract: PURPOSE: To simplify a circuit, to eliminated the need for stand-by current and to stably enable holding and controlling an operation voltage by connecting the capacitor plate electrode of a cell to a power source supply holding line. CONSTITUTION: When switching elements 44 and 46 are turned on, a voltage higher than a holding voltage Vh by 1Vt is generated in a node 45. When a driving transistor 50 is turned on, a power source voltage Vcc is applied to a holding line 22, to precharge bit lines 10 and 11. Then, the level of a line end signal ϕrc is lowered, the elements 44 and 46 are turned off with a logic circuit 42, the holding line 22, FET 48 and the node 47 are separated from the node 45. A power source Vcc is also separated from a capacitor 52, and the voltage Vh+Vt of the node 45 is kept to be applied to the gate electrode of the transistor 50. Therefore, the holding line 22 is clamped to the holding voltage Vh after the elements are turned-off, the leakage of the voltage is eliminated and holding is executed during a precharge period.

When a carrier signal is outputted from the counter 11, the motor 2 is stopped for a prescribed time, and after that, it is rotated in a reverse direction, and is driven until a time when an initial position detecting sensor 7 detects the initial position of the optical system 1 by using the through-up and the through-down. After detection, the motor, after being rotated reversely in its own start up area, is rotated forward, and detects the initial position and stops. Therefore, it is possible to miniaturize the device and to shorten the reading time without moving the optical system to a position other than the required area of the original.

Finally, the shape line is extracted on the basis of the characteristics of the shape line and other lines. When a cut line is generated in the shape line, the cut line position is detected and its connecting processing is executed.

Title: Emitter-follower type output circuit
Inventor: FUTATSUKA KAZUTSUGU
IPC: H03K19/086
Filed: 1990-10-01
Abstract: PURPOSE:To enable the number of test pins to be reduced and output current to be reduced by providing a switching transistor for cutting on or off by lowering base potential of a transistor (Tr) for emitter follower. CONSTITUTION:When H signal is fed to a cut-off signal input terminal CTI of an emitter follower type output circuit which is terminated within a chip, the output circuit performs normal output circuit operation. When L signal is fed, a Tr for cut-off switch 36 is turned on, thus enabling the corresponding current to flow and a Tr for emitter follower 37 to be cut of due to potential drop at a resistor 38 and disabling function as an output circuit. Namely, by cutting of the Tr for emitter and follower 37 if not needed when performing test, influence to environment can be eliminated. Thus, by feeding a specified cut-off signal to a specified number of output circuits, output current where IC changes can be reduced by the same number of output circuits to be turned off, thus preventing malfunction or oscillation due to transient current when performing test.
