Patent number: 10153182Abstract: A substrate processing apparatus that performs processing by immersing a substrate into a processing liquid obtained by mixing phosphoric acid with a diluent includes a concentration sensing means for sensing the concentration of the processing liquid by measuring the absorbance characteristics of the processing liquid. The concentration sensing means includes a light-transmitting section that introduces the processing liquid into the inside to let the processing liquid pass therethrough, a light-emitting section that radiates light having a predetermined wavelength to the light-transmitting section, a light-receiving section that receives the light therefrom via the light-transmitting section, a first lens that condenses the light emitted from the light-emitting section to the light-transmitting section, a second lens that condenses the light that has passed through the light-transmitting section to the light-receiving section, and a cooling mechanism that cools at least one of these.Type: GrantFiled: August 29, 2012Date of Patent: December 11, 2018Assignees: Kurashiki Boseki Kabushiki Kaisha, Tokyo Electron LimitedInventors: Noboru Higashi, Satoru Hiraki, Hiromi Kiyose, Hideaki Sato, Hiroshi Komiya

Patent number: 8705037Abstract: A liquid component concentration meter measures the concentration of a liquid in a liquid supply tube from outside the liquid supply tube. The concentration meter includes a liquid supply tube; a light transmission unit; a light emission unit for irradiating light to the light transmission unit; a light reception unit for receiving light passed through the light transmission unit; a support member that movably supports the light emission unit and the light reception unit such that a measurement position is moved along the light transmission unit; a measurement-position moving mechanism for moving the support member such that the measurement position is moved within a predetermined area in the light transmission unit; and a data processing unit for calculating the concentration of the liquid in the liquid supply tube based on intensities of light received by the light reception unit at different measurement positions.Type: GrantFiled: August 31, 2009Date of Patent: April 22, 2014Assignee: Kurashiki Boseki Kabushiki KaishaInventors: Hiroshi Yokota, Satoru Hiraki, Nobuyoshi Yasuda

Patent number: 6427108Abstract: A control system for an automatic vehicle transmission, in which the running resistance acting on the vehicle and the driving force generated by the vehicle are calculated, and a slope of a road on which the vehicle travels is estimated based on at least the calculated running resistance and the driving force. The vehicle running state is then discriminated by comparing the estimated slope with a predetermined value. The maximum driving force to be generated by the vehicle at the current gear ratio is calculated to determine a driving force difference from the calculated driving force and the gear ratio of the transmission is determined such that the driving force difference is a predetermined value in response to the discriminated running state, thereby enhancing the drivability.Type: GrantFiled: July 16, 1999Date of Patent: July 30, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsumi Kanasugi, Satoru Hiraki, Shuji Nagatani
