Abstract: PURPOSE:To reduce field values at each portion of a bushing to an allowable value simultaneously and take coordination of insulation such as to be capable of minimizing the damage of the bushing when dielectric breakdown occurs by providing at the end portion of an internal grounding shield a bent portion whose radius of curvature varies from bushing inner wall side to high-voltage conductor side in the ratio of approximately 1:2. CONSTITUTION:The end portion of an internal grounding shield 7 is bent toward a high-voltage conductor 10 and this bent portion varies in radius of curvature from bushing inner wall side 8 to high-voltage conductor side 9 in the ratio of approximately 1:2. The bent portion of the end of the internal grounding shield should preferably be disposed near the root of a bushing rib which is nearest to the boundary between the cylindrical portion 2 and the conical portion 3 of the inner wall of a bushing 1. In this case, an electric field on the high-voltage conductor side 9 at the end of the internal grounding shield can be reduced to a lower value and also the electric field of the high-voltage conductor 10 can be lowered. Electric fields at each portion of the bushing can thus be reduced to below an allowable value simultaneously and cooridation of insulation can be taken so that even in case of dielectric breakdown the damage of the gas bushing can be minimized.

When d/t is below 1.2, the effect for the improvement in compression resistance becomes insufficient and, when d/t exceeds 2.5, lamina tion becomes impossible. When the amount of the filler is below 1%, the effect for the improve ment in compression resistance becomes insufficient and, when said amount exceeds 5%, the bonding strength of the laminated layer an a metal plate and damping capacity are lowered.

Abstract: PROBLEM TO BE SOLVED: To execute injection by a PVT method (injecting of a sample in a liquid) in a simple structure by a constitution wherein an inner wall of a glass insert to be attached to a specimen vaporizing chamber is formed of frosted glass. SOLUTION: A needle is penetrated to a septum 12 until the tip thereof reaches an inner section of a glass insert 20 to eject a liquid specimen from a pinhole of a side face of the needle. The needle is rotated and the liquid specimen is stuck to a whole circumference of a face 23 of frosted glass of an insert 20. At that time, the inner wall surface of the insert 20 is applied with the frosted glass treatment so that the liquid specimen does not drop therefrom to stay in the face 23.

After that, when a heater 13 is heated at a temperature control section 14, the liquid specimen stuck on the face 23 is vaporized. It is introduced into a capillary column 15 to separate the component so that it is detected by a detector 16.  It is thereby possible to hold the liquid specimen on the face 23 even in a simple structure and to execute the injection and analysis by a PVT method.
