Publication number: 20150293181Abstract: Provided is a simple secondary battery tester that obtains, without applying an AC signal for determination based on capacitance, the capacitance of a secondary battery from time characteristics of a current flowing to the secondary battery and a terminal voltage and determines whether the secondary battery is degraded based on the capacitance thus obtained. The secondary battery tester includes a voltage sensor 32 for measuring a terminal voltage of a secondary battery 10 and a current sensor 34 for measuring the current. The secondary battery tester, without applying the AC signal, obtains capacitance C from measured values of time characteristics of the voltage and the current those being measured and compares the preliminarily stored reference capacitance with the capacitance C derived from the measured values, thereby determining whether the secondary battery is degraded.Type: ApplicationFiled: October 10, 2013Publication date: October 15, 2015Inventor: Futao KANEKO

Patent number: 7843570Abstract: A substance adsorption detection method and a sensor utilizing amounts of change in the optical characteristic of a sensitive thin film with respect to the adsorbed amount of a substance to be detected. A clad 4, a core 5, and a thin film 7 for detecting an adsorbed substance are sequentially stacked on a crystal oscillator 10 to constitute an optical waveguide layer 12 and a gas adsorption member 11. An incoming light prism 8 and an outgoing light prism 9 are provided on the surface of the core 5. Changes in the adsorbed mass of the target substance and in the optical characteristic involved can be detected accurately and simultaneously by utilizing a change in outgoing light originating from a change in propagation loss and a change in the oscillation characteristic of the oscillator 10, both caused by adsorption of the target substance on the core surface.Type: GrantFiled: July 28, 2005Date of Patent: November 30, 2010Assignee: Niigata UniversityInventors: Kazunari Shinbo, Futao Kaneko, Keizo Kato, Yasuo Ohdaira, Takahiro Kawakami

Publication number: 20080022755Abstract: The invention provides a gas detection method and a gas sensor which utilize an amount of change in the electrical characteristic of a gas sensitive thin film with respect to the adsorption amount of a gas to be detected. The gas sensitive thin film (7) having characteristic detection electrodes (5, 6) functioning as a sandwich electrode or a gap electrode is laid out on a crystal resonator (10), and change in the electrical characteristic of the gas sensitive thin film (7) with respect to the adsorption amount of the detection target gas is observed by simultaneously determining change in the oscillatory frequency of the crystal resonator (10) and the electrical characteristic of the gas sensitive thin film (7). Because the sensor is an integral type device, both changes in an adsorption mass and the electrical characteristic can be surely monitored.Type: ApplicationFiled: July 12, 2005Publication date: January 31, 2008Applicants: Weidmann Plastics Technology AG, NIIGATA UNIVERSITYInventors: Kazunari Shinbo, Futao Kaneko, Keizo Kato, Yasuo Ohdaira, Takahiro Kawakami, Masahiro Minagawa
