An electron beam recording apparatus is disclosed that records information onto the surface of a sample by using an electron beam. The electron beam recording apparatus includes an electron source that irradiates the electron beam, a magnetic detector that is configured to move onto and out of an irradiation axis and acquires magnetic information on the irradiation axis, a convergence position control part that calculates a convergence position correction amount for correcting a convergence position of the electron beam with respect to the surface of the sample based on the magnetic information, and a convergence position adjusting part that adjusts the convergence position of the electron beam with respect to the surface of the sample. The convergence position control part causes the convergence position adjusting part to adjust the convergence position of the electron beam with respect to the surface of the sample based on the convergence position correction amount.

There is provided a circular disc-shaped rotary wheel comprising a luminescent light emitting area in which a luminescent material is provided along a circumferential edge of the circular disc shape, an annular step portion which is formed at a different level from a reference plane which is a surface where the luminescent light emitting area is formed, and a balance correction material which is placed at the annular step portion, wherein the balance correction material is placed at the annular step portion so as to even a rotational balance when the rotary wheel is rotated.
摘要:
An ejection liquid capable of being stably ejected based on a system using thermal energy even if the liquid contains at least one selected from the group consisting of proteins and peptides, and a method and an apparatus for ejecting the liquid containing at least one selected from the group consisting of proteins and peptides using this system are provided. The applicability of the liquid for use in an inkjet system using thermal energy is improved by adding at least one selected from the group consisting of amino acids and salts thereof and a surfactant to an aqueous solution containing at least one selected from the group consisting of proteins and peptides.
