Title: Focusing method in charged particle beam device
Inventor: ASARI TOSHIHIRO
IPC: H01J37/21
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To make accurate automatic focusing possible without producing the omission of a necessary wave form in automatic focusing operation, and capable of keeping the distinctive feature of a sample within the scanning range of an electron beam even if a scanning distance is narrowed. SOLUTION: As the pre-stage of focusing operation, magnification for focusing is assigned in a computer 5. The computer 5 calculates the distance S1 of the actual spot by the magnification. The maximum effective scanning distance S2 is previously set in the computer 5. The maximum effective scanning distance S2 is the distance at which the omission of wave form information is not produced. The computer 5 compares two kinds of distances S1 and S2 , and if S1 is larger than S2 it converts the distance of the scanning spot in the scanning direction of electron beams from S1 to S2 , and makes the magnification in the scanning direction of electron beams high.

Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To check the occurrence of inconvenience in measuring such as a slip phenomenon by providing a slip discrimination part or the like for discriminating whether an error between three-dimensional correction positions is in a specified range. SOLUTION: A three-dimensional position operation part 31 calculates the three-dimensional correction positions HXk, HYk (k indicates integer of 1 to n) of a measuring point Qk on the basis of base line vectors K1, K2 transmitted and the three-dimensional positions KJ1, KJ2 of two known points stored in a memory part 35. Next, an error operation part 42 calculates an error DS between these correction positions HXk, HYk on the basis of the three- dimensional correction positions HXk, HYk. That is, since the correction positions HXk, HYk are on the positions of a three-dimensional coordinate, the error DS is found as a distance of the three-dimensional coordinate between the correction positions HXk, HYk. The error DS is transmitted to a slip discrimination part 32, which discriminates whether the error DS is in a specified range.

Title: Ceramic-inserted piston and manufacture therefor
Inventor: HIRAI SADAAKI
IPC: F02F3/26
Filed: 1991-07-25
Abstract: PURPOSE:To enhance the degree of bondability between the ceramics portion and the metal portion by casting the ceramics portion and the metal portion in a manner to provide a projecting portion on the metal portion, and machining the projecting metal portion after casting so as to cause this portion to have a height conforming to that of the ceramics portion. CONSTITUTION:In covering a ceramic piston head portion 1 with molten metal, 2 covering metal 2 is cast so that it may upwardly project from the upper surface of ceramic portion. The projected metal portion 3 only is machined until its height comes into conformity with the height of the ceramics portion If the covering metal 2 has a high surface tension or the degree of wettability between the metal 2 and the ceramics is low, the height of the outer peripheral portion (where the thermal conditions are not severe) of the ceramics portion top surface is increased, whereby the metal is cast up to a height equal to or greater than this increased height. Then, the ceramics and the projected metal portion 3 are machined until the height thereof comes into comformity with that of the inner peripheral portion (where the thermal conditions are severe) of the ceramics portion top surface. Thus, the machining of the ceramics portion or the ceramic portion where the thermal conditions are severe becomes unnecessary.
