Title: Ferrite single crystal
Inventor: YORIZUMI MINEO
IPC: C10G49/00
Filed: 1980-05-16
Abstract: PURPOSE: To make the growth of ferrite single crystal easy and to reduce the magnetostriction of the single crystal, by using a specific composition of the Li-Fe-Mn- Zn type.  
     CONSTITUTION: The ferrite single cyrstal of this invention has a composition shown by the formula I (x=0.1W0.4,  y=0.3W0.55). Since a given amount of Mn 2+  is replaced by a part of Li + -Fe 3+ , the single crystal is grown easily with reduced equilibrium oxygen pressure without damaging magnetic properties. The magnetic head materials using this ferrite single crystal slightly cause procesing deterioration resulting from magnetostriction or sliding noise brought about by the slipping between a magnetic tape and a head.

Title: Delay circuit and semiconductor storage device
Inventor: SUZUKI KOICHI
IPC: H03K5/13
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction after a signal exceeds the threshold of a logic circuit by gently changing the switch of an input signal by a charging/ discharging means, switching an output signal when a charging/discharging signal from the charging/discharging means exceeds the threshold and changing the time constant of the charging/discharging in accordance with the switch of the output signal of the logic circuit. SOLUTION: A switch element 4 controlled by the output signal OUT of an inverter 3 is provided between capacity 2 and a node N1. The switch element 4 is turned on in an initial state and the voltage change of the input signal IN is blunted by the time constants of resistance 1 and capacitance 2. Then, timing when the voltage of the node 1 exceeds the threshold voltage of the inverter 3 is delayed. When the output signal OUT of the inverter 3 changes, the switch element 4 is turned off. Thus, the occurrence of an unnecessary change is prevented even if the input signal IN changes owing to noise and the fluctuation of power voltage after the output signal OUT changes.
