Patent number: 11640895Abstract: There is provided a sample holder capable of reducing positional deviation of a cartridge in the heightwise direction of a sample. The sample holder includes the cartridge and a holder base having a mounting portion for the cartridge. The mounting portion includes a placement surface, a first tilted surface, and a rotary drive mechanism for imparting a rotary force to the cartridge. The cartridge includes an opposing first tilted surface opposite to the first tilted surface of the mounting portion. As the rotary drive mechanism imparts the rotary force to the cartridge, the first tilted surface of the cartridge is pressed against the first tilted surface of the mounting portion, whereby the cartridge is pressed against the placement surface.Type: GrantFiled: January 7, 2022Date of Patent: May 2, 2023Assignee: JEOL Ltd.Inventors: Shuichi Yuasa, Takahisa Kawamura

Patent number: 5786832Abstract: An ink-jet recording head has ejection outlets formed by treating a face of a plate for the ejection outlets with a water-repellent and irradiating the plate with a laser beam from the backside of the plate. The head is provided with a sealing member for sealing the ejection outlets. The water-repellent has a hardness of higher than the pencil hardness 6B at room temperature. A decomposition product layer is formed on the layer of the water repellent at peripheral portions of the ejection outlets.Type: GrantFiled: July 22, 1994Date of Patent: July 28, 1998Assignee: Canon Kabushiki KaishaInventors: Akihiro Yamanaka, Takashi Watanabe, Hiroyuki Ishinaga, Takahisa Kawamura, Seiichiro Karita, Norio Ohkuma, Masahiko Higuma, Akira Goto, Teruo Arashima, Motoaki Sato, Megumi Saito

Patent number: 5341161Abstract: An ink recorder includes an ink recording section of which ink passage has a small cross-sectional area. For this reason, the ink passage has an opening portion at a bent part thereof which serves as a venting hole for allowing air to be vented from a molding die to the outside therethrough during a molding operation. To prevent ink from leaking from the ink passage, a spherical sealing member is fitted into the opening portion. Since the opening portion is molded of a deformable material, a spherical sealing member made of a metallic material while having a diameter slightly larger than an inner diameter of the opening portion can be fitted into the opening portion.Type: GrantFiled: June 12, 1992Date of Patent: August 23, 1994Assignee: Canon Kabushiki KaishaInventors: Koji Yamakawa, Takahisa Kawamura, Teruo Arashima
