Publication number: 20130010293Abstract: A light emitter emits light with a plurality of wavelengths towards a test object held in a spectrophotometer tool. A light receiver receives the light passing through the test object. A detector detects absorbances of wavelength components from the light received by the receiver. An optical path length calculator compares, in the absorbances of the wavelength components detected, a wavelength component absorbance of light absorbed by a pigment that absorbs light with a wavelength other than a wavelength of light absorbed by an analyte in the test object and a predetermined value of the wavelength component absorbance to calculate an optical path length passing through the test object. A corrector corrects the wavelength component absorbance detected excluding the wavelength of the light absorbed by the pigment using the optical path length calculated by the optical path length calculator to calculate a corrected wavelength component absorbance in a reference optical length.Type: ApplicationFiled: July 5, 2012Publication date: January 10, 2013Applicant: ARKRAY, INC.Inventors: Akio Okubo, Tsutomu Nakamura

Patent number: 8222776Abstract: A power supply unit superimposes alternating-current voltage on direct-current voltage and applies it to a motor. As a result, when the motor is rotated, a current containing an alternating-current component flows. Further, the motor includes a capacitor connected in parallel with one phase coil. Owing to this capacitor, the impedance of the motor circuit between brushes is varied according to the rotation of the motor. Variation in impedance appears as variation in the amplitude of the alternating-current component in motor current. A signal processing unit extracts an alternating-current component from the motor current detected by the current detection unit and generates a rotation pulse corresponding to variation in the amplitude. A rotation angle detection unit detects the rotation angle of the motor based on this rotation pulse.Type: GrantFiled: August 5, 2009Date of Patent: July 17, 2012Assignee: Denso CorporationInventors: Ken Tanaka, Tsutomu Nakamura, Kenji Takeda, Masaru Touge, Yasuhiro Fukagawa
