Title: Semiconductor memory
Inventor: SAITO YOSHIKAZU
IPC: G11C11/407
Filed: 1989-05-31
Abstract: PURPOSE:To increase an access speed at the time of reading and, simultaneously, to prevent a recording data destruction at the time of writing by making the input threshold of a data value selecting switch circuit for writing higher than the input threshold value of a data line selecting switch circuit for reading. CONSTITUTION:A common data line and a data line selecting switch circuit are provided separately for a common data line CLR for reading, a data line selecting switch circuit 3R for reading and a common data line CLW for writing and a data line selecting switch circuit 3W for writing, and only the input threshold of the switch circuit 3R is increased by the intervention of a high threshold executing circuit 6. Thus, an action threshold at the time of reading and an action threshold at the time of writing are independently set, respectively, and the fear of a stored data destruction at the time of writing can be made small without lowering the access speed at the time of reading.

Title: Method and apparatus detecting liquid level
Inventor: ARA KATSUYUKI
IPC: G01F23/24
Filed: 1980-10-07
Abstract: PURPOSE: To detect water levels in pressure devices of nuclear reactors, etc., with a wide detecting range and a high accuracy under a condition where any erroneous operations can easily be detected, without complicating the constitution, by transforming the electromotive force generated by the thermocouple element forming a plural number of temperature measuring contact points when the thermocouple element detects liquid levels, into binary signals.  
     CONSTITUTION: A cold junctin 9 and a plural number of temperature measuring contact points 14... are installed, and, when a thermocouple element formed with thermocouple element wires 13',13, etc., at odd numbered detection spans 1,2,... detects a liquid level L at an even numbered detection span, no electromotive force is generated by the thermocouple element. The same may occur even when the number of the detection span is even number and, in this case, a liquid level judging circuit 11 generates binary signals in accordance with the liquid level L. Therefore, when similar thermocouple elements TC 1 , TC 2 ,... having different arrangement of temperature measuring contact points, respectively, are combined, a wide range and highly accurate liquid level detection can be performed for a long range formed in a narrow detection span without complicating the constitution. Moreover, when a thermocouple element for parity check PTC is used, erroneous operations caused by breakages of elements TC 1 ... or noises can be detected easily and surely.

Title: Liquid metal ion source
Inventor: ISHITANI TOORU
IPC: H01J27/26
Filed: 1984-07-09
Abstract: PURPOSE:To increase the life and the reliability of a liquid metal ion source by periodically or continuously introducing a reducing gas around a needle-like anode and a reservoir for an ionization substance. CONSTITUTION:When ionic radiation becomes instable, while an ionization substance 2 is maintained in a molten state the output voltage of a lead-out power supply 8 is cut off and then the ionization substance 2 is exposed for 10min to hydrogen gas which is used as a reducing gas and leaked through a valve 9 until its pressure level reaches one atmospheric pressure. As the result, copper oxide is reduced to form an original copper surface. Next, after a vacuum is again produced around the ionization substance 2, a load-out voltage is applied to the ionization substance 2 to produced stable ions. Consequently, it is possible to regenerate the ion source and to increase the life and the reliability of the liquid metal ion source.
