Patent number: 7030377Abstract: In an infrared imaging device, shutting means 40 is configured so that it can be opened/closed and so as to shut off an infrared radiation coming into an optical system 20 when it is closed. During an imaging operation, the shutting means 40 is opened, and the optical system 20 causes an infrared radiation from an object 70 to form an image on an infrared detector 10. The infrared detector 10 outputs a signal according to the amount of infrared light received by each pixel. Correction means 30 corrects sensitivity variations among pixels, the influence of the infrared radiation from the optical system 20, etc. During a calibration operation, the shutting means 40 is closed, and the correction means 30 determines a correction coefficient for correcting fluctuations in the amount of infrared radiation from the optical system 20 by using the output of the infrared detector 10 imaging the shutting means 40.Type: GrantFiled: January 6, 2005Date of Patent: April 18, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tsuyoshi Mekata, Taro Imagawa, Koji Morikawa

Publication number: 20060036498Abstract: Distribution of the parts (parts A, parts B), including shipment by a part supplier, delivery to the part orderer to be used in product manufacturing, is divided into stages in time-sequence (under transportation or at a location including the parking lot, warehouse, temporary storage facility, line side, etc.) and each stage is inputted with incoming and outgoing quantity information of the part orderer to compute the quantity of inventory from a difference therebetween. Information on the computed quantity of inventory is sent through terminal computers to a host computer such that it consolidates the sent information to be centralized and manages at a lump. Further, among of the quantities of inventory at divided stages, the quantity of inventory computed based on the incoming and outgoing quantity information of the part orderer is recognized as the actual quantity of inventory.Type: ApplicationFiled: September 19, 2003Publication date: February 16, 2006Applicant: HONDA GIKEN KOGYO KABUSHIKI KAISHAInventors: Koichi Iida, Hidenobu Tanaka, Motokazu Otsubo, Takafumi Jodoi, Taro Imagawa

Patent number: 6996280Abstract: An image coding apparatus includes an image feature extraction means for generating character data which includes character codes corresponding to character images included in a document image and auxiliary information indicating the sizes and positions of the respective character images in the document image based on image data indicating the document image. The image coding apparatus generates a predictive document image for the document image based on the character data, and subjects the document image data to arithmetic coding in which the probability model is changed with reference to predictive document image data. In the image coding apparatus, the probabilities of white pixels and black pixels indicated by the probability model are very close to those in the character image, whereby the coding efficiency for the character image data in the arithmetic encoder is improved.Type: GrantFiled: June 9, 1999Date of Patent: February 7, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihiko Matsukawa, Taro Imagawa, Tsuyoshi Mekata, Kouichi Hata, Minoru Eto

Publication number: 20050289022Abstract: There are provided with an order quantity computing technique (S16, S18) that computes a relatively short-term part order quantity based on the actual quantity of the parts so as to decrease the quantity of inventory and to achieve a stable part supply, and an order quantity computing technique (S22, S24) that computes a relatively long-term order quantity based on the tentative quantity of inventory of the parts (a quantity of inventory computed based on the past production records) so as to obtain mass production effects such that one of them is selected to be used by comparing the price of the parts with the prescribed price (S14). With this, it becomes possible to easily change the part order quantity computation technique in response to the lead time of the parts, thereby enabling to effectively utilize the advantages of two different part order quantity computation techniques.Type: ApplicationFiled: September 19, 2003Publication date: December 29, 2005Inventors: Koichi Iida, Hidenobu Tanaka, Motokazu Otsubo, Takafumi Jodoi, Taro Imagawa
