Patent number: 10114032Abstract: In step S101, a specimen containing blood plasma and a coagulation activating agent are introduced into a flow channel, with the coagulation activating agent being positioned ahead, in a state in which portions arrayed in series in the extending direction of the flow channel flow in contact with each other. In step S102, in the process in which the coagulation activating agent, the contact region between the coagulation activating agent and the specimen, and the specimen pass through a measurement portion provided midway along the flow channel in the order named, the refractive indices of the coagulation activating agent and the contact region are measured in a time-series manner. In step S103, the blood coagulation ability of the specimen is measured by comparing the first refractive index value which is the refractive index of the coagulation activating agent with the second refractive index value which is the minimum refractive index of the contact region.Type: GrantFiled: May 21, 2014Date of Patent: October 30, 2018Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Suzuyo Inoue, Katsuyoshi Hayashi, Yuzuru Iwasaki, Tsutomu Horiuchi, Nobuaki Matsuura, Emi Tamechika

Patent number: 5477502Abstract: In a semiconductor random access memory device having a memory cell array, each of the memory cells includes a flipflop circuit having two opposite terminals as a data holding element. The flipflop circuit is applied with "1" and "0" signals to the two opposite terminals, those applied signals are held at the opposite terminals, respectively. In order to small size the memory device by avoiding use of a pair of write signal lines for writing data signal to the memory cell, the memory cell is provided with an inverter circuit connecting between the two terminals of the flipflop circuit. A data signal is applied to one of two terminals through a single write signal line, while is applied to the other terminal as an inverted signal through the inverter circuit.Type: GrantFiled: July 8, 1994Date of Patent: December 19, 1995Assignee: NEC CorporationInventor: Katsuyoshi Hayashi
