Patent number: 10775456Abstract: A sample pipe is provided in a sample temperature control pipe. A detection coil is provided in a low-temperature airtight chamber and configured to irradiate a sample with a high-frequency magnetic field. A room-temperature shield is provided on an outer circumferential surface of the sample temperature control pipe or on an inner circumferential surface thereof, and is configured to block irradiation of the high-frequency magnetic field from the detection coil from reaching a region other than an observation object. A low-temperature shield is provided in an airtight chamber and between the detection coil and the room-temperature shield and is configured to block irradiation of the high-frequency magnetic field from the detection coil from reaching the room-temperature shield.Type: GrantFiled: April 24, 2019Date of Patent: September 15, 2020Assignee: JEOL Ltd.Inventors: Katsuyuki Toshima, Shigenori Tsuji, Shinji Nakamura, Fumio Hobo, Takeshi Tsukada, Akifumi Nomura

Patent number: 10705164Abstract: A pair of detection coils, one coil provided on each side of a sample container across the width of the sample container. The detection coil is made of a superconductor and has an electric circuit pattern capable of detecting a magnetic resonance signal from a sample. The detection coil includes a lateral component intersectional to a static magnetic field H0 and having a part disposed at a position spaced away from a detection region, as compared to the remaining part.Type: GrantFiled: May 11, 2017Date of Patent: July 7, 2020Assignee: JEOL Ltd.Inventors: Fumio Hobo, Katsuyuki Toshima, Shinji Nakamura, Shigenori Tsuji, Ryoji Tanaka, Hiroto Suematsu

Patent number: 10114089Abstract: A sample tube is arranged in a sample temperature adjusting pipe, and a temperature adjustment gas is supplied. A vacuum vessel is formed with the sample temperature adjusting pipe and an outer wall body, and a detection coil and the like to be placed in a cooling state are arranged in the vacuum vessel. A sealed section between the sample temperature adjusting pipe and the outer wall body is sealed by a sealing structure. The sealing structure includes a high-vacuum O-ring and a low-temperature O-ring. The high-vacuum O-ring has characteristics for sealing the sealed section in a regular temperature region. The regular temperature region is a temperature region excluding a low temperature region, and the low temperature region is a temperature region including a lower limit in a possible temperature adjustment range of the temperature adjustment gas. The low-temperature O-ring has characteristics for sealing the sealed section in the low temperature region.Type: GrantFiled: January 11, 2017Date of Patent: October 30, 2018Assignee: JEOL Ltd.Inventors: Katsuyuki Toshima, Shinji Nakamura, Shigenori Tsuji

Patent number: 10073153Abstract: A device for attaching and detaching a cryogenic probe to and from a nuclear magnetic resonance (NMR) spectrometer. The device permits the probe to be loaded in the spectrometer in a shortened time and achieves high measurement throughput. The device has loading platforms (11-1, 11-2) on which cryogenic probes (P1, P2) are loaded. Each loading platform has a horizontal drive mechanism, a vertical drive mechanism, and a spacing mechanism. The device further includes probe cooling devices (14-1, 14-2) for circulating a refrigerant to and from the cryogenic probes (P1, P2) via transfer tubes (12-1, 12-2) made of a flexible material, thus cooling the probes (P1, P2). A temperature-controlled gas feeder (18) supplies a temperature variable gas for temperature adjustment to the probes (P1, P2). A vacuum pumping system (15) evacuates the interiors of the probes (P1, P2) via vacuum pipes (17-1, 17-2) made of a flexible material.Type: GrantFiled: November 18, 2014Date of Patent: September 11, 2018Assignee: JEOL Ltd.Inventors: Masanori Hirose, Yoshiaki Yamakoshi, Masahide Nishiyama, Shinji Nakamura, Katsuyuki Toshima, Fumio Hobo, Terumasa Okada, Shigenori Tsuji, Ryoji Tanaka, Hiroto Suematsu
