Abstract: PURPOSE:To absorb such periodic energy as earthquake motion so effectively by setting up a hermetically sealed vessel and a resistance wing axis free of relatively rotational displacement with this resistance wing axis as the center according to the relative displacement between structures, and installing a resistance wing, making lead in this vessel into shearing deformation, in this axis. CONSTITUTION:When strong periodic energy such as earthquake motion or the like acts between structures 1, 4, this relative displacement is converted into rotational displacement via linkage. With this conversion, a hermetically sealed 8, where loacked lead is sealed in, and a resistance wing axis 13, piercing and extending an operating chamber of this vessel 8 and placing a resistance wing in this operating chamber, both are made into relatively rotational displacement with the resistance wing axis 13 as the center. In consequence, the resistance wing shears and deforms the lead sealed in the operating chamber, and it absorbs periodic energy consumption at this time. With absorption of this periodic energy, the relative displacement, namely, the earthquake motion between the structures is thus absorbable.

Title: Inductively coupled plasma/mass spectrometer
Inventor: NISHI NOBUHIKO
IPC: G01N27/62
Filed: 1994-07-28
Abstract: PURPOSE:To prevent recombination of an ion in a plasma with an electron to enhance efficiency of the ion passing through a sampling orifice and improve detecting sensitivity in a detector of mass spectrometer. CONSTITUTION:An electrode 9 connected to a constant voltage power source 11 via a switch 12 is arranged between a plasma torch 2 and a sampling orifice 4, and an electron in a plasma 3 is attracted to the electrode 9 side to prevent recombination of an ion in the plasma with the electron so that the ion can efficiently pass through the sampling orifice without being damaged. The switch 12 is opened at the time of plasma turning-on so as to prevent high frequency power from being applied to the electrode 9 due to inductive coupling at that time. Since the inductive coupling between the plasma 3 and an induction coil becomes strong after the time of plasma turning-on to prevent application of the high frequency power to the electrode 9, the switch 12 is closed to maintain voltage of the electrode 9 at a fixed value, for example, 5-20V.
