Patent number: 10872745Abstract: A charged-particle beam system comprises: a charged-particle beam device containing a detection unit for detecting electrons generated by irradiating a sample with a charged-particle beam released from a charged particle source; and a signal detection unit in which a detection signal from the detection unit is input through a wiring. The signal detection unit comprises: a separation unit for separating into a rising signal and a falling signal the detection signal from the detection unit; a falling signal processing unit for at least eliminating ringing in the falling signal; and a combination unit generating and delivering a combined signal produced by combining the rising signal, which has been separated by the separation unit, with the falling signal wherefrom the ringing has been eliminated by the falling signal processing unit.Type: GrantFiled: March 27, 2017Date of Patent: December 22, 2020Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Akio Yamamoto, Kazuki Ikeda, Wen Li, Hiroyuki Takahashi, Shahedul Hoque, Shunsuke Mizutani

Publication number: 20200268307Abstract: A swallowing movement measuring device measures an examinee's swallowing movement. The device measures a movement of the examinee's larynx when the examinee swallows a food bolus. This device has a capacitive sensor to be brought into contact with a body skin of the examinee's laryngeal part, and a measuring unit that measures a change of the capacitive sensor in capacitance. This capacitive sensor includes a sensor body comprising sheet-like dielectric layer, a first electrode layer and a second electrode layer. The first and the second electrode layers are formed on a top surface and a bottom surface of the dielectric layer respectively, and are at least partially opposed to each other across the dielectric layer. The partially opposed portions of the electrode layers constitute a detection portion. The sensor body is reversibly deformable to change areas of the top and bottom surfaces of the dielectric layer.Type: ApplicationFiled: December 22, 2016Publication date: August 27, 2020Applicant: BANDO CHEMICAL INDUSTRIES, LTD.Inventors: Masashi OHTA, Hideo OTAKA, Yusuke BESSHO, Akira ISHIKAWA, Akio YAMAMOTO, Kaoru HANAIE, Takumi YAMAGUCHI, Ken UMEHARA

Patent number: 10088150Abstract: To enable a carbonized material production kiln to be maintained in a simple manner when an exposed surface on a side wall of the kiln is cracked, to prevent the kiln from easily cracking by heat to thereby prolong the life of the kiln itself, and to increase heat retention efficiency to thereby increase carbonization efficiency even during periods of cold temperatures such as the winter season. The carbonized material production kiln is formed by stacking cubic concrete blocks each having no reinforcing iron so that recombination of up to six faces of each cubic concrete block becomes possible, wherein a heat storage/retention member such as stones is filled in an exhaust space formed between a kiln floor iron plate and a kiln bottom so as to store heat, thereby preventing a decrease in carbonization efficiency even at cold temperatures.Type: GrantFiled: July 26, 2013Date of Patent: October 2, 2018Assignee: YAMAMOTO BIO-CHARCOAL MFG.
