Patent number: 10475953Abstract: A passage (3) for a sample solution is formed in a sapphire base body (2) used as a substrate for semiconductor devices. An LED (4) and a photodiode (5) are formed on the base body (2) by a semiconductor manufacturing process so that they face each other across the passage (3). The LED (4) emits light into the base body (2). This light is transmitted through the sample solution in the passage (3), undergoing absorption according to the concentration and other properties of the solution. The transmitted light passes through the base body (2) and reaches the photodiode (5), producing a detection signal corresponding to the incident light amount. Since the light source and photodetector are integrated with the base body (2) serving as a flow cell, the present device is small and lightweight. Furthermore, no cumbersome task of aligning optical axes in the device-assembling process is needed.Type: GrantFiled: April 24, 2015Date of Patent: November 12, 2019Assignee: SHIMADZU CORPORATIONInventor: Yusuke Nagai

Publication number: 20190096561Abstract: In a stepwise structure formed in a multilayer coil component, a difference occurs in a shrinkage amount between a maximum film thickness portion in which the number of layers is large and a minimum film thickness portion in which the number of layers is small due to portions different in the number of layers of coil parts (that is, upper coil part, lower coil part, and connecting part) adjacent to each other like the maximum film thickness portion and the minimum film thickness portion, readily causing a crack by an inner stress due to the difference in the shrinkage amount. In a multilayer coil component according to the present disclosure, a stress relaxation part overlapping with a maximum film thickness portion whose shrinkage amount is large is provided to relax inner stress in a stepwise structure, resulting in prevention of a crack.Type: ApplicationFiled: September 20, 2018Publication date: March 28, 2019Applicant: TDK CORPORATIONInventors: Yusuke NAGAI, Takashi SUZUKI, Hidekazu SATO, Takashi ENDO, Kouichi KAKUDA, Kunihiko KAWASAKI, Shinichi KONDO, Yuya ISHIMA, Shinichi SATO, Masaki TAKAHASHI

Patent number: 10126229Abstract: Measurement light is cast from a light-casting unit into a flow cell. The light is repeatedly reflected at an outer surface of the flow cell. A detecting unit including a connecting element and a photodetector element is provided in contact with the outer surface of the flow cell. Since the connecting element is made of a material whose refractive index is higher than that of the wall of the flow cell, the light is extracted from the flow cell at the contact position of the connecting element, to be detected by the photodetector element. A shift of the attachment position of the detecting unit along the axis of the flow cell changes the optical path length of the measurement light. A high-sensitivity absorption measurement can be performed by controlling the optical path length by merely changing the attachment position of the detecting unit, without replacing the flow cell.Type: GrantFiled: April 24, 2015Date of Patent: November 13, 2018Assignee: SHIMADZU CORPORATIONInventor: Yusuke Nagai

A predetermined voltage is applied from a drift voltage generator to the resistive film layers of both ends of the drift cell so that an accelerating electric field having a linear potential gradient is formed along a center axis (C) in a desolvation region and a drift region inside the drift cell. Ions are drifted by the accelerating electric field and are separated in response to the ion mobility.Type: ApplicationFiled: August 24, 2015Publication date: August 30, 2018Applicant: Shimadzu CorporationInventor: Yusuke NAGAI

Patent number: 10041914Abstract: A degassing device 2 includes: a built-in absorbance measurement section 28 using an LED light source and measuring the intensity of light transmitted through a mobile phase passing through a flow cell; and a solenoid valve 26 switchable between two states with and without the mobile phase passed through a degassing tube 21.

A signal processor 29 calculates the difference in absorbance based on those detection signals, estimates the degree of degassing based on that difference, and displays the result on a display unit 32.Type: GrantFiled: June 2, 2017Date of Patent: August 7, 2018Assignee: SHIMADZU CORPORATIONInventors: Kumiko Jingu, Keisuke Ogawa, Masato Watanabe, Yusuke Nagai, Masanori Fujiwara, Tomoyuki Yamazaki
