Publication number: 20230400384Abstract: This abnormality detection device is provided with a first encoder for detecting the rotation angle of an input shaft of a decelerator, and a second encoder for detecting the rotation angle of an output shaft of the decelerator. An operation control unit controls a servo motor such that the position acquired from the output of the second encoder corresponds to a position determined by an operation program. A detection unit calculates the angle difference, which is the difference between the rotation angle acquired from output of the first encoder and the rotation angle acquired from output of the second encoder. The detection unit determines whether or not the decelerator is abnormal on the basis of the angle difference.Type: ApplicationFiled: November 8, 2021Publication date: December 14, 2023Applicant: Fanuc CorporationInventor: Yoshiaki Yokoyama

Patent number: 9964408Abstract: An observer measures a flow velocity of sea surface with beam, and a coastal wave height. A predictor predicts a next time state vector, from a state vector including flow velocity of each range cell of beam, a wave height difference between range cells, and a coastal wave height. First calculator calculates a prediction error covariance matrix from a smoothing error covariance matrix. Second calculator calculates a gain matrix using results obtained by the observer and the first calculator. Third calculator calculates a smoothing error covariance matrix using results by the observer, the second calculator, and the first calculator. The state vector is smoothed for each wave height difference, from results by the observer, the predictor, and the second calculator. The wave height of each range cell is calculated by adding the wave height and the wave height difference in toward-offshore direction, using the wave height difference smoothing.Type: GrantFiled: November 20, 2014Date of Patent: May 8, 2018Assignee: Mitsubishi Electric CorporationInventors: Tetsutaro Yamada, Yoshiaki Yokoyama, Yasushi Obata

Patent number: 7381383Abstract: A treatment apparatus of the present invention includes a hermetic door 115b and a retort 115c as an interface for taking out a gaseous emission containing vaporized substances from an object to be treated which is being heated in a reduced pressure state in a second hermetic chamber 103 while maintaining conditions in the second hermetic chamber. When the retort 115c is inserted into a first opening 103b of the second hermetic chamber, the hermetic door 115b in an open state is shielded from the second hermetic chamber 103, whereby condensation of the gaseous emission at the hermetic door is prevented. Accordingly, condensates can be taken out while conditions such as temperature and pressure in the hermetic chamber are maintained without the treatment apparatus being stopped. The productivity of treatment is greatly improved by continuous operation of such a treatment apparatus.Type: GrantFiled: November 10, 2000Date of Patent: June 3, 2008Assignee: Hoei Shokai Co., Ltd.Inventors: Yoshiaki Yokoyama, Toru Kodama, Yasuo Mishima, Katuo Takamiya, Tsuyoshi Abe, Hitoshi Mizuno

Patent number: 7156027Abstract: An object to be treated such as soil, burned fly ashes, or the like containing organic halides is introduced to a hermetically sealable thermal decomposition furnace 310 and heated under reduced pressure. Emitted gases of the object to be treated are treated so that the generation and recomposition of dioxins are supressed. A heated residue of the object to be treated is cooled after being purged with a purge gas which is organic halide-free and has no organic halide generating capacity. Thus, the concentration of organic halides remaining in the heated residue can be held to an extremely low level.Type: GrantFiled: September 29, 2000Date of Patent: January 2, 2007Assignee: Houei Syoukai Co., Ltd.Inventors: Yoshiaki Yokoyama, Tooru Kodama, Yasuo Mishima, Katuo Takamiya

Patent number: 5205857Abstract: A method for recovering substance such as zincing or the like adhered to the surface of an object to be processed, by causing such materials to be evaporated in a vacuum. In this method, the object to the processed is placed in a furnace provided with heating means; the temperature within the furnace is elevated up to a predetermined level with the aid of an oxidizing gas atmosphere; the pressure in the furnace is reduced so that the quantity of the oxidizing gas is reduced to be below the explosion limit; and vaccum or a reducing gas atmosphere is fed into the furnace to reduce the oxidization of the object to be processed. Thereafter, the interior of the furnace is evacuated while being maintained under a predetermined evaporation temperature condition; and the substance evaporated from the object to be processed is passed to recovery means provided in communication with the furnace, so that the substance thus evaporated is condensed in the recovery means and recovered therefrom.Type: GrantFiled: December 26, 1991Date of Patent: April 27, 1993Assignee: Ogihara Technical Center Co., Ltd.Inventor: Yoshiaki Yokoyama

Patent number: 4963740Abstract: A subtraction processing method for radiation images comprises the steps of obtaining a masked image signal by reading out a masked image of an object recorded without injection of contrast media into a specific structure of the object, and obtaining a live image signal by reading out a live image recorded after contrast media have been injected into the specific structure of the object. The parts of the masked image signal and the live image signal corresponding to the same picture elements in the masked and live images are subtracted, thereby obtaining a difference signal for forming an image of the specific structure. In cases where different read-out conditions are used when obtaining the masked image signal and the live image signal, one of the masked image signal or the live image signal is converted into the image signal which would have been obtained if the same read-out conditions had been used for both images.Type: GrantFiled: March 9, 1989Date of Patent: October 16, 1990Assignee: Fuji Photo Film Co., Ltd.Inventors: Eiichi Asai, Yoshiaki Yokoyama
