Abstract: PURPOSE:To seal water in a highly reliable manner by fitting a ring in a gap between the inner circumferential surface of a main mounting hole and the outer circumferential surface of a main, and enlarging a ring groove installed in an end face of this ring with a pipe piece or the like. CONSTITUTION:A ring 11 made of flexible material is fitted in a gap between the inner circumferential surface of a main mounting hole 4 of a manhole 3 and the outer circumferential surface of a main 5. In addition, pipe pieces 35 plurally divided in the circumferential direction are set up in a ring groove 31 formed in an end face 30 of this ring 11. In succession, a nut 43 screwed in a bolt 17 is screwed therein, whereby these pipe pieces 35 are pushed forward via two pipe keep plates 37 and 37', and thus the ring groove 31 is enlarged as specified. If so, the ring 11 is pressed to an interval between the inner circumferential surface of the main mounting hole 4 and the outer circumferential surface of the main 5, sealing a gap between both of them. With this sealing, even in the case where there is eccentricity between the main mounting hole 4 and the main 5, an overhanging quantity of the ring 11 is partially adjustable, so water is sealable in a highly reliable manner.

Title: Method and device for implanting negative oxygen ion with pulse bias
Inventor: MIYAKE KOJI
IPC: H01J27/02
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To limit the kind of generated oxygen ion to one kind and to eliminate the need for mass separation, by extracting negative ions from an oxygen plasma and by introducing them into an Si substrate. SOLUTION: An oxygen gas is introduced into a plasma generating chamber 30 and a trigger circuit 45 turns on a first switch 40. A high-frequency voltage is applied across an opposite electrode 32 and a susceptor electrode 31 to generate a glow discharge between the electrodes, which generates oxygen plasma. When the trigger circuit 45 is turned off, the first switch 40 is turned off to destroy the plasma, and an electron loses energy instantly and becomes a low energy level of several eV. This electron with low energy is dissociated and attached to an oxygen molecule to generate a negative oxygen ion. Therefore, the density of the negative oxygen ions starts to increase abruptly just after the trigger circuit 45 is turned off. The negative oxygen ions are generated with higher priority by enhancing gas pressure and electric field by increasing microwave power to be applied.

Title: Inspection device
Inventor: TSUKAMOTO TAKASHI
IPC: G01R31/28
Filed: 1993-06-07
Abstract: PURPOSE:To shorten inspection process time for improving productivity by removing bias component in the output signal without providing time constant circuit that contains a capacitor, at inspecting an IC for A.C. signal process. CONSTITUTION:One input terminal of a differential amplifier 18 is connected to an output terminal 17 of a test IC 11, and the other one is connected to a bias terminal 15 of the IC 11. When the IC 11 is mounted on a jig 12, a switch SW 2 is closed, and then a power supply 14 is turned on, the output terminal 17 rises to be bias electric potential V0, in addition, a bias terminal 15 also rises to be V0. Thus difference in electric potential disappears, so that the electric potential at an output terminal 31 of the differential amplifier 18 is kept at 0V, and under active state of the IC 11, the bias voltage on the output side can be removed. Under this condition, A.C. signal is supplied to the IC 11 from a signal generation circuit 23 through an input terminal 30, and only A.C. signal component is taken out of the output terminal 31, so that the electric characteristics of the IC 11 are measured (24), for determination of its correctness (25). If this inspection process is automated, a slight shortening of the time leads to improved productivity.
