Patent number: 10052713Abstract: A bonding target member 1 having a solid bonding material 3 with aluminum as a main component is interposed between a metal member 2 and a ceramic member 4 and an elastic member 12 are pressurized by a pressurizing section 13 and a bonding tool section 15 of a resonator 14 in a vertical direction. The bonding tool section 15 of the resonator 14 resonates with sound vibration or ultrasound vibration transmitted from an oscillator 16. An interfacial portion between the metal member 2 and the bonding material 3 with aluminum as a main component and an interfacial portion between the bonding material 3 with aluminum as a main component and the ceramic member 4 each receive pressurization and vibration energy to be bonded together. The metal member 2 and the ceramic member 4 can be bonded together at ordinary temperature in the atmosphere with the bonding material 3 with aluminum as a main component.Type: GrantFiled: August 17, 2016Date of Patent: August 21, 2018Assignee: ULTEX CORPORATIONInventors: Shigeru Sato, Ryoichi Ishii, Takahiro Ito, Mayumi Kouya

Publication number: 20180111220Abstract: A bonding target member typically has a solid bonding material with aluminum as a main component interposed between a metal member and a ceramic member. These elements and an elastic member are pressurized by a pressurizing section and a bonding tool section of a resonator in a vertical direction. The bonding tool section of the resonator resonates with sound vibration or ultrasound vibration transmitted from an oscillator. The metal member and the ceramic member can alternatively be bonded together without the intermediate bonding material. In both cases, bonding at ordinary temperature in the atmosphere is possible. When the ceramic member has a thickness resistant to pressurization and vibration energy at the time of bonding to resist cracking, the elastic member may be disposed on the metal member side, or may not be used.Type: ApplicationFiled: December 20, 2017Publication date: April 26, 2018Applicant: ULTEX CORPORATIONInventors: Shigeru SATO, Ryoichi ISHII, Takahiro ITO, Mayumi KOUYA

Patent number: 7875858Abstract: The invention relates to a trajectory correction method for a charged particle beam, and provides a low-cost, high accuracy and high-resolution converging optical system for use with a charged particle beam to solve problems with conventional aberration correction systems. To this end, the present invention uses a configuration which forms electromagnetic field which is concentrated towards a center of a beam trajectory axis, causes oblique of the beam to make use of lens effects and bend the trajectory, and consequently, cancels out large external side non-linear effects such a spherical aberration of the electron lens. Specifically, the configuration generates an electric field concentration in a simple manner by providing electrodes above the axis and applying voltages to the electrodes. Further, the above configuration can be realized trough operations using lenses and deflectors with incident axes and image formation positions that are normal.Type: GrantFiled: January 7, 2009Date of Patent: January 25, 2011Assignee: Hitachi High-Technologies CorporationInventors: Hiroyuki Ito, Yuko Sasaki, Ryoichi Ishii, Takashi Doi
