Title: Method for decreasing occurrence or growth of crack in surface of metal part
Inventor: PIITAA RUISU ANDORESEN
IPC: G21C13/087
Filed: 1995-03-24
Abstract: PURPOSE: To provide a method of reducing generation or growth of a crack on a surface of a metal part in a water cooling type nuclear reactor or its related equipment. CONSTITUTION: A method includes a step for filling solution or suspension of a pH adjusting compound in reactor water. The pH adjusting compound is added by amount so that pH in a tip of a crack or in a portion where the crack tends to be generated is within a range of about 6.5-8.0 unrelated to electrochemical potential (at high temperature). The compound is resolved under temperature condition of the nuclear reactor and emits S or atom for adjusting pH of the reactor water. pH of thus adjusted reactor water is within 6.5-8.0.

Title: Tunnel structure
Inventor: TAMURA NAOAKI
IPC: E21D11/04
Filed: 1993-03-01
Abstract: PURPOSE:To prevent a flood in an urban area. CONSTITUTION:A lining 3 comprising a plurality of segments 31 is constructed in a region at a depth lower than groundwater level WL in the ground 2 so as to withstand earth pressure, i.e., external pressure, exerted by the ground 2. A steel pipe 6 is installed in the interior of the lining 3 in such a manner that an annular gap 10 is formed between the pipe 6 and the lining 3, and shock absorbing materials 7 are filled into the gap 10 so that rainwater is admitted into a water passage space 9 inside the pipe 6 at the time of a heavy rainfall so as to be discharged. At this moment, the deformation of the pipe 6 due to the internal pressure caused by the differences in water head or impulsive water pressure is absorbed by the elastic materials 7 in the gap 10, and hence the internal pressure is transmitted to the lining 3 so that tightly connected conditions between the segments 31 are prevented from being broken.

Title: Switching circuit with high dielectric strength
Inventor: FUKUMA MASAO
IPC: H01L29/786
Filed: 1980-05-19
Abstract: PURPOSE:To obtain dielectric strength double as high as that of a unit transistor (TR) by applying a reference voltage, which sets the operating point of a circuit, between the source and gate of one TR and by inputting a signal voltage, which controls the conductive resistance of the circuit, to the gate of another TR. CONSTITUTION:The drain of a TR11, the source of a TR12, and the gate and drain of a TR14 are connected together. Further, the source of the TR14, the gate of the TR12, and the drain of a TR13 are connected together; and a reference voltage Vref setting the operating point of a circuit is applied between the source and gate of the TR13, and a signal voltage VIN controlling the conductive resistance of the circuit is inputted to the gate 21 of the TR11 to control the lead-in resistance between the source of TR11 and the drain of the TR12. Then, the threshold level of each TR is denoted as VT, and voltages at a connection point 23 and terminal 24 as a V23 and V24 respectively. In this case, when the Vref is so set that Vref= V23+VIN+VT, the TRs 11 and 12 are equal in on resistance, so V24=2XV23. Consequently, the circuit operates as a switching circuit which has dielectric strength twice that of one unit TR.

Title: Automatic and manual switching device for controller
Inventor: FURUKUBO YUJI
IPC: G05B7/02
Filed: 1986-03-24
Abstract: PURPOSE:To obtain an AM (automatic/manual) switching device having high reliability by using a circuit which monitors the deviation between the automatic control signal and the manual tracking signal at the time of an automatic operation and gives the alarm to outside in case the deviation is kept at a large level. CONSTITUTION:A time of an automatic operation mode (manual request signal 3b kept positive), a delta high/low monitor circuits monitors the deviation value between output signals 1a and 13a in a monitor circuit 20. Then the output signal 21 of the circuit 21 is set positive when said deviation value is larger than a fixed level. The output of an AND circuit 22 is positive when the signal 21a is positive since the signal 3b is positive. An ON delay timer 23 sets its output signal 20a at a positive level in case the output of an AND circuit 22 is kept positive longer than a fixed time. While at the time of a manual operation (signal 3b kept negative), the output of the circuit 22 is always kept negative together with the signal 20a of the timer 23. Thus the wrong alarm is never delivered even though the output signal 21a of an automatic control circuit 1 is set an abnormal level.
