Title: Sealant injecting jig
Inventor: TADA SHINICHIROU
IPC: F16L55/18
Filed: 1991-03-22
Abstract: PURPOSE:To repair a leakage of piping urgently but accurately without stopping the operation of a plant by inserting a sealant injecting jig, made up of forming such a material as low in hardness into a truncated conical form, into a leakage part of the piping and, after installing it with a mounting jig, injecting a sealant thereinto. CONSTITUTION:When a drain valve causes an internal leakage and thereby steam is blown off to a funnel 5, first of all, a mounting jig 11 is attached to this funnel 5, and a sealant injecting jig 21 is inserted into an opening part of a drain pipe 3. At this time, this injecting jig 21 is formed into a truncated conical form from material of gunmetal or the like being low in hardness as compared with piping, through which the leakage from the jig outside is kept back after getting it fitted to the pipe. In succession, a sealant injecting hole 22 and a vent hole 23 are installed in the injecting jig 21, and these elements are opened to the top and side of the truncated cone, while they are interconnected to a hydraulic cylinder and a vent pipeline. Furthermore a pressing rod 13 with threads is screwed in a pedestal 12 of the mounting jig 11, and this tip is engaged with a recess 25 on a bottom surface of the truncated cone.

Filed: 1989-04-04
Abstract: PURPOSE:To operate a comparator normally to a low input voltage even when a power voltage is low by providing plural transistors(TRs) whose emitters are connected to an input terminal and a current mirror circuit or the like. CONSTITUTION:Emitters of NPN TRs Q10, Q11 are connected respectively to input terminals 3, 4 and a common constant current source 6 is connected to each base. Then the collector output of the TR Q10 is fed to PNP Trs Q12, Q13 constituting the current mirror circuit and the collector output of the TR Q13 is fed to NPN TRs Q14, Q15 constituting other current mirror circuit and the TR Q15 is connected in parallel with the NPN TR 5. Even in the case of 0<=VIN<VBE5 (base-emitter forward voltage of TR Q5), when VIN<VREF, since the TRs Q1, Q5 are not turned on but the TR Q10 is turned on, the TRs Q12, Q13 are turned on, the TRs Q14, Q15 are turned on and the voltage VOUT at the output terminal 5 reaches an L level. Thus, the comparator is normally operated to the low input voltage even when the power supply voltage is low.

The current sensitivity and the sensitivity increase/decrease information are shown with an arrow on a display 20. The length of the arrow shoes sensitivity dimensions and the direction of the arrow shows the sensitivity increase/decrease information. A user who sees the arrow knows the current sensitivity and further predicts how sensitivity will change in the further.  It is preferable to adjust the waiting time that is a processing cycle, in accordance with the moving speed of a mobile body.
