Title: Semiconductor storage device
Inventor: OKAJIMA YOSHINORI
IPC: G11C11/34
Filed: 1984-05-30
Abstract: PURPOSE:To reduce a power consumption caused by a holding current, and to prevent a storage data from being broken down by an influence, etc. of alpha rays, by executing a control so that a holding current of a memory cell is added or made to flow, when an internal voltage drop of the memory cell becomes below a prescribed value. CONSTITUTION:In case a voltage drop between each word line W1 and H1 is larger than a voltage drop portion of a diode D1, a transistor Q1 becomes off, a transistor Q2 becomes on, and a transistor Q4 is cut off. Accordingly, information of each memory cell is held only by a charge accumulated in its inside. On the other hand, when a potential difference between the word line W1 and H1 becomes lower than the voltage drop portion of the diode D1, the transistor Q1 becomes on, the transistor Q2 becomes off, the transistor Q4 becomes on, a holding current is made to flow to each memory cell MC, and when the potential difference between the word line W1 and H1 increases, the transistor Q4 is cut off again, and the holding current is decreased or cut off.

Title: Thin film magnetic head
Inventor: KAWAKAMI HIROJI
IPC: G11B5/31
Filed: 1987-05-06
Abstract: PURPOSE:To obtain a wider coil width with respect to the same rail width by adopting the structure in such a way that a tilt angle of the end shape of a part at least close to a rail except the part with a magnetic core formed thereupon is made steep on an organic resin thereby decreasing the difference between the width of the organic resin and the width of coil. CONSTITUTION:In a magnetic head comprising the organic resin layer 1 coating and insulating an electric winding and a magnetic thin film formed on the organic resin layer and forming a part of the magnetic path of the magnetic head, the tilt angle of the end face near the rail side end of the organic resin layer 1 is made steeper than the tilt angle of the part covered by the magnetic thin film. In the case of increasing the organic resin tilt angle of a part close to the side end of the rail in this way, the width of the organic resin film 1 is decreased. Thus, thermal noise of the electric winding due to the resistance and heat at recording are reduced and the quantity of transmission of a high frequency signal to a reproducing signal amplifier is increased.
