Title: Error correcting device and error correcting method
Inventor: KUROKAWA SATOSHI
IPC: H03M13/00
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To suppress error correction probability and to improve the reliability of data by optimizing the strategy of error correction with repeat count. SOLUTION: The repeat count of correction is set to a setting register 9, and a sequence controller 16 performs detection correction in a PI direction (horizontal direction to an information symbol) up to the number of capability limitation of codes by an error correction arithmetic circuit 15. When it is discriminated that an error remains through a count value of a correction line number counter 17, the elimination correction in a PO direction (vertical direction to the information symbol) is performed, and in the case of the correction in a final direction, the correction of the number of capability limitation of codes is not performed.

Title: Sorter
Inventor: SHIMOKAWARA JUN
IPC: B41J13/00
Filed: 1987-07-31
Abstract: PURPOSE:To prevent possible occurrence of faulty discharge in advance by providing a guide part which presses paper against a paper feed roller and a paper feed roller alternately before each receiving part. CONSTITUTION:Paper 4 in a guide part 5 received from a paper receiving inlet 7 is introduced into a gap between a paper feed roller 2 and a guide part 3. At that time, the paper 4 is pressed against the paper feed roller 2 by means of the guide pert 3 positioned on the paper feed surface side of the paper feed roller 2, and then is discharged into a paper receiving part 1 by virtue of the flexibility of the paper and the rotation of the paper feed roller 2. When paper is not inserted, no rotational load occurs against the paper feed roller, in spite of the rotation of the paper feed roller, because the guide part 3 is positioned between the paper feed rollers 2.

Abstract: PURPOSE:To obtain a rotor capable of preventing damage and capable of separating small specimen particles, by providing a through-hole capable of permitting the passage of a liquid only from above to the axis of a rotor core in the up-and-down direction to allow a cooling fluid through said through-hole. CONSTITUTION:A specimen 16 is flowed in the ring shaped cavity in a rotor body from below through a passage 28 in such a state that a rotor is stopped. At this time, the penetration of a liquid into a through hole 24 is prevented by a spherical float 26. The end part of a liquid passing hole 19 is closed and the rotor body 1 is rotated. When arrangement is generated to a centrifugal force direction at about 3,000rpm, a buffer solution innoxious to the specimen 16 is flowed from above. The buffer solution flows down through the through- hole 24 to be discharged while pushing away the spherical float 26. By this method, operation can be performed while a seal or a bearing is cooled. A high-density extruding liquid 30 is injected from below in a rotary state and the specimen in the rotor body 1 is recovered. By fractionating and taking in the discharged liquid in parts, the specimen can be separated.

Title: Detecting device for interruption cycle abnormality of cpu
Inventor: SUEKANE KAZUO
IPC: G06F9/48
Filed: 1986-08-18
Abstract: PURPOSE:To surely detect the interruption cycle abnormality by using a counter which counts clock pulses to count the interruption cycles produced by an interruption signal generating circuit. CONSTITUTION:A counter 3 counts clock pulses and is reset by the interruption signal produced from an interruption signal generating circuit 2. A CPU 1 discriminates whether the value obtained before the counter 3 is reset is kept within a normal value range or not by the interruption processing carried out by the interruption signal. The counter 3 shows the value equivalent to a period between a reset mode set by the previous interruption signal and a reset mode of this time. Therefore the CPU 1 can detect occurrence of the cycle abnormality of the interruption signal by discriminating the value of the counter 3. While a priority interruption signal is produced to the CPU 1 in case the count value of the counter 3 reaches a specific level before the counter 3 is reset. Thus the CPU 1 detects immediately a fact that no interruption signal is produced within a fixed period of time in a priority processing mode.
