Patent number: 9209002Abstract: A Geiger-Muller counter tube includes an enclosing tube, an anode conductor, a cathode conductor, an inert gas, and a quenching gas. The enclosing tube is at least partially cylindrical and has a sealed space. The anode conductor includes an anode electrode and a linear first metal lead portion. The anode electrode is arranged inside the space and formed in a rod shape. The first metal lead portion is connected to the anode electrode and supported at an end of the enclosing tube. The cathode conductor includes a cylindrical cathode electrode and a linear second metal lead portion. The cathode electrode surrounds a peripheral area of the anode electrode inside the space. The second metal lead portion is connected to the cathode electrode and supported at the end of the enclosing tube. The cathode electrode has a side surface through a part of which a through-hole passes.Type: GrantFiled: December 4, 2014Date of Patent: December 8, 2015Assignee: NIHON DEMPA KOGYO CO., LTD.Inventors: Toshiaki Takeuchi, Kunio Hamaguchi, Kuichi Kubo, Kozo Ono, Noritoshi Kimura

Patent number: 9190250Abstract: A radiation measurement apparatus for measuring radiation includes a first and second Geiger-Muller counter tubes and a radiation-direction calculating unit. The first Geiger-Muller counter tube seals an electrode within a circular pipe-shaped enclosing tube that extends in a straight line. The first Geiger-Muller counter tube is arranged along a first direction. The second Geiger-Muller counter tube seals an electrode within a circular pipe-shaped enclosing tube that extends in a straight line. The second Geiger-Muller counter tube is arranged in a second direction intersecting with the first direction. The radiation-direction calculating unit is configured to compare a first detection signal and a second detection signal with one another to calculate a direction of radiation to be emitted from the sample. The first detection signal is output from the electrode of the first Geiger-Muller counter tube. The second detection signal is output from the electrode of the second Geiger-Muller counter tube.Type: GrantFiled: June 17, 2014Date of Patent: November 17, 2015Assignee: NIHON DEMPA KOGYO CO., LTDInventors: Toshiaki Takeuchi, Kozo Ono, Kuichi Kubo, Kunio Hamaguchi

Publication number: 20150155144Abstract: A Geiger-Muller counter tube includes a cylindrical enclosing tube, an anode electrode, a cylindrical cathode electrode, a bead, an inert gas, and a quenching gas. The cylindrical enclosing tube has a sealed space. The anode electrode is disposed inside the space and formed in a rod shape. The cylindrical cathode electrode surrounds a peripheral area of the anode electrode inside the space. The bead is formed of an insulator and having a through-hole in the center, the anode electrode passing through the through-hole. The bead is secured to the anode electrode in a position where the anode electrode is surrounded by the cathode electrode. The inert gas and the quenching gas are sealed inside the space. The bead prevents a direct contact between the anode electrode and the cathode electrode.Type: ApplicationFiled: December 3, 2014Publication date: June 4, 2015Inventors: TOSHIAKI TAKEUCHI, KUNIO HAMAGUCHI, KUICHI KUBO, KOZO ONO, NORITOSHI KIMURA
