Title: Sample analyzing method and sample analyzing device
IPC: H01J49/14
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To form a particle beam source as a simple structure by adjusting kinetic energy of an emitted primary ion to a low value so that a surface of a sample is not substantially flattened by enriching the surface of the sample by the primary ion, and adjusting the kinetic energy of the primary ion to a high value so that the surface of the sample is flattened by a primary ion beam in the next place. SOLUTION: A primary ion beam 1A of a primary ion source 2 is applied to a surface of a sample 1 at an optional irradiating angle relative to a normal, and a secondary ion emitted from the sample 1 is analyzed by a mass spectrometer 3. In this case, first of all, energy of the primary ion beam 1A is reduced more than threshold value energy to sputter the sample 1, and an area close to the surface of the sample 1 is enriched by a primary ion. Next, the energy of the primary ion beam 1A is remarkably enhanced, and the sample 1 is flattened. The energy is adjusted by an emitting parameter of the primary ion source 2. Therefore, a device can be made compact.

IPC: G01S7/52
Filed: 1985-06-21
Abstract: PURPOSE:To adjust the increase/decrease and adjusting extent of frequency by reducing partially the thickness of cylindrical vibration body. CONSTITUTION:A board thickness cutting part 5 is positioned at the connecting side of a piezoelectric element 3 against the node of a vibration mode in an elliptic cylindrical vibration body 4 and a board thickness cutting part 6 at the opposite side of the connecting side of the piezoelectric element 3 against the node of the vibration mode.

Outline shapes 7 and 8 represents a shape before the elliptic cylindri cal vibration body is driven by the tension/compression movement of the piezoe lectric element 3 in the major axis of ellipse and the shape after it is transformed. For example, the elliptic cylindrical vibration body 4 is divided into twenty sections along with its circumference and when sensitivity DELTAf/DELTAt between a characteristic frequency (f) and a board thickness (t) at respective point is observed, the positions where a large transform extent is observed are four positions at the neighbor of the node 11 and at the root part where the piezoelectric element 3 is contacted, transformation is scarcely obserbed because rigidity is so big with lowering the sensitivity DELTAf/DELTAt to about 1/5-1/10 compared with other positions.

Abstract: PROBLEM TO BE SOLVED: To securely close a lead outlet by rotatably mounting a cover at a cover fixing member, and locking a protrusion of the cover to a protrusion of the member at the time of tilting down the cover to close the outlet. SOLUTION: In the case of closing a lead outlet 2A, a rising cover 4 is tilted down so that a top 4F of a rotary shaft 4D urges to lift an upper edge, thereby enlarging a mounting hole 2E. When the top 4F is inclined to a right side, the hole 2E tends to close, and the cover 4 is automatically tilted down, and hence a protrusion 4B of the cover 4 is brought into contact with a protrusion 3D of a cover fixing member 2. And, when the cover 4 is forcibly tilted down, the shaft 4D is oscillated to right side, and the protrusion 4B of the cover 4 is locked over the protrusion 2D of the member 2.
