  • Patent number: 8911810
    Abstract: An organic fertilizer and an organic feed are produced by removing cadmium from processing residues of scallop (Patinopecten yessoensis) without separating the midgut gland. That is, a small amount of an aqueous citric acid solution is added to the processing residues of scallop including the midgut gland in which cadmium has been accumulated at a high concentration and the mixture of them is heated to 55 to 65° C. Thus, the thin midgut gland membrane is broken and the internal solution of the midgut gland containing cadmium is eluted. Then, solid matters are separated from the mixture including the solid matters and the internal solution of the midgut gland eluted. As the aqueous citric acid solution, a solution prepared by mixing at least 9% by weight of water relative to the processing residues and 1.8 to 3.3% by weight of citric acid relative to the total weight of the processing residues and water is used.

  • Patent number: 7012199
    Abstract: Correction of coordinates input by a user through an input device is effected using coordinate correction parameters. To calculate the coordinate correction parameters, a plurality of reference points are displayed on the input device. Coordinate input is designated by a user, and if the coordinate is determined to correspond to a reference point, then the coordinate input is retained. The process is repeated until a coordinate is kept for each reference point, wherein only remaining reference point(s) for which a corresponding coordinate has not yet been retained are displayed. Once coordinates have been input for the reference points, a correspondence between coordinate input and a reference point is determined, and corresponding coordinates are kept for each reference point. Using correction parameters calculated based on the kept coordinates, it is possible to correct device characteristics of the input device such as position aberration, even if such characteristics are non-linear.

  • Patent number: 6338075
    Abstract: An automatic linking process of sequentially searching pages which are hierarchically constructed such as a WWW browser. Control is provided such that an instruction from an automatic linking instruction device is used as a trigger, and a first non-read anchor is searched by an anchor search device. If there is a non-read anchor, a hypertext of a network on the link destination side is accessed, and if there is no non-read anchor, a processing routine is returned to the original page. Thus, upon reading the hypertext, operability is improved due to the automatic linking process.

  • Patent number: 6323839
    Abstract: A pointed-position detecting apparatus where image output unit visually displays an image, and image input unit inputs the displayed visible image. The input visible image is stored into memory as an original image. The visible image is partially changed by using a manipulation device such as a laser pointer or a pointing rod, and the visible image with the partially-changed area is inputted from the image input unit. Controller extract the changed image area from the input visible image, and detects a pointed position based on the changed image area. Thus, the phenomenon where a user's action with respect to a displayed image is reflected as a change in the image is utilized to detect coordinates and motion at the image area as the object of change.

  • Patent number: 6031634
    Abstract: An image information transmitting/receiving apparatus for time and cost-saving repetitive transmission. In facsimile communication, image data where further information is added to previously-transmitted image data is often received. In the present apparatus, the original image data is stored, and only difference data from the original image data is transmitted, thus the whole image can be reproduced at the receiving side, using the received difference data. Upon transmitting the difference image information, identification information identifying the difference image information is added to the difference information, and the entire image data to be received by the receiving side is stored. Upon receiving the difference image information, the received difference information is combined with the stored image data, and an image is reproduced based on the combined image data. Further, the image data used for image reproduction is stored as original image data for the next transmission.

  • Patent number: 5982928
    Abstract: A system consisting of a plurality of terminals connected through communication is sometimes used to acquire information input from the terminals to a host terminal and edit/arrange the information in the host terminal when information is exchanged by inputting handwritten characters from the terminals. In this case, the host terminal must recognize the handwritten characters and thereafter process the characters to arrange the handwritten character information. Each terminal can perform character recognition by a unique character recognizing method. The terminals also individually prepare dictionaries for recognition. The host terminal returns the acquired handwritten character information to the terminals and causes the terminals to perform character recognition. Alternatively, the host terminal concentratively manages the character recognizing methods and dictionaries of all the terminals and performs character recognition.

  • Patent number: 5828568
    Abstract: An information processing apparatus, which operates in a multi-task mode, calculates a total consumption power of devices used by each task, and assigns higher execution priority to a task which uses a device with the largest consumption power, thereby shortening the execution time of the device with the largest consumption power, and suppressing the total consumption power of the apparatus. When a device is started upon switching of tasks, if the total consumption power exceeds the allowable power of the apparatus by a power consumed upon restarting of the device, the task is set in a waiting state until operations of other devices are completed, the consumption power is lowered, and it is ready to use the device by the task.
