Title: Magnetic disk and its retrying method
Inventor: HAYASHI KATSUMI
IPC: G06F3/06
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic disk which realizes a performance improvement effect that the data transfer rate between the magnetic disk and a host controller at or above a certain threshold is secured. SOLUTION: A retrying method and retrial frequency specification are added to a command issued by the host controller. A memory for occasional writing is stored with retrial history management information on error processes. The magnetic disk interprets a command (40) and interprets a retrying method (44) when the method is specified (41). When a retrial frequency is specified (42), the frequency is interpreted (45). On the basis of the retrial history information, retrial is optimized (50) and the command is executed (43). When neither the retrying method nor the retrial frequency is specified, retrial is done by the prescribed retrying method of the magnetic disk as many times as prescribed.

Title: Car distribution ticket issuing and fetching system linking computer readable action instruction information and teaching result record for driving school
Inventor: NOMURA HIDEKI
IPC: G06Q50/10
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To provide a car distribution ticket issuing and fetching system linking computer readable action instruction information and the teaching result for a driving school. SOLUTION: In the driving school, only teaching conditions are extracted as data out of the teaching information of various huge patterns on an acquisition target driving license, a teaching stage and a student and these data are transmitted to an instructor while using a visible medium (document) called car distribution ticket so that efficient and exact teaching can be supported. Since the data of the teaching result can be directly recorded on the car distribution ticket, time required for recording data can be remarkably shortened and further, erroneous recording of data can be prevented. Besides, since that document is used as the input medium of a computer system as it is, there is no recording omission or erroneous reporting at the time of information transmission and data can be exactly inputted to the computer system.

Title: Production of metallic tube
Inventor: SEINO NAOYOSHI
IPC: B21C37/083
Filed: 1990-12-19
Abstract: PURPOSE:To prolong the service life of a metallic tube while keeping the inner part of the metallic tube in a rust prevention treated state by removing a rust- preventing agent only from both edges of a metallic tape, which is previously treated with the rust-preventing agent, and then performing welding. CONSTITUTION:A metallic tape 3 to which a rust-preventing agent is previously applied is curved so that both edges 3a turn downward, respectively, and both the edges 3a are immersed in a cleaning device 4 to undergo cleaning, by which only the rust-preventing agent applied to both edges 3a is removed. The rust- preventing agent remains adhering to the central part of the metallic tape 3. As a result, when the metallic tape 3 in which both edges 3a alone are cleaned is formed into tubular shape 8 by means of a forming device 7 and both the edges 3 are welded, the inner part of the metallic tube 8 can be kept in a rust prevented state and the service life can be prolonged. Moreover, the amount of the solvent used is minimized because the size large enough to immerse respective both edges 3a of the metallic tape 3 suffices for respective cleaning solvent storage sections 16.

IPC: F25B49/02
Filed: 1990-12-28
Abstract: PURPOSE:To simplify the circuit constitution and controls by protecting equipment in a refrigerating machine such as a compressor, etc., systematically against an abnormal high-or low-pressure. CONSTITUTION:A first signaling device HPS outputs a stop signal when the pressure of a refrigerant circuit 9 rises in excess, and a second signaling device LPS outputs a stop signal when the pressure of the refrigerant circuit 9 excessively drops. Stop signals from the signaling devices HPS and LPS are counted by a counter 33. A compressor 1 is automatically reset corresponding to a stop signal by a reset processor 51, and on the other hand, when the counted value of the counter 33 reaches the set value, equipment in a refrigerating machine are stopped by an abnormality processor 52. When a thermo-off signal is issued from the room side, the counted value of the counter 33 is reset, so that stop signals caused by transitory abnormal high- or low-pressure are prevented from being cumulated.
