Title: Duplex stainless steel
Inventor: SHIBATA TAKASHI
IPC: C22C38/44
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain a duplex stainless steel in which the precipitation of sigma phases is delayable without sacrifying its corrosion resistance by allowing the steel to have a compsn. contg. specified amounts of Ni, Cr and Mo, and the balance Fe with inevitable impurities and regulating the tolerance of Si in the impurities to a specified range. SOLUTION: This duplex stainless steel has a compsn. contg., by weight, 2 to 10% Ni, 20 to 30% Cr, 1 to 5% Mo, and the balance Fe with inevitable impurities. Then, the allowable content of Si in the impurities is prescribed to 0.005 to 0.1%. Ni stabilizes austenite as either phase in the duplex steel. Cr assures the corrosion resistance of the alloy and stabilizes ferrite as the other phase. Mo improves its pitting corrosion-resistance and crevice corrosion resistance in particular. Si in the impurities is preferably reduced to the utmost since it remarkably promotes the precipitation of sigma phases, but, on the other hand, since it is important as a deoxidizing element, its content is regulated to the above range.

Title: Parallel program verification device
Inventor: UCHIHIRA NAOSHI
IPC: G06F11/28
Filed: 1994-09-14
Abstract: PURPOSE: To perform the branch cut processing in a short time in a state where a reduced global state transition graph is produced by providing an auxiliary transition addition means which adds an auxiliary transition to transfer the priority from the transition that secures the synchronization among processes to the transition of the process of the other side. CONSTITUTION: An auxiliary transition addition device 1 transfers the priority from the transition that secures the synchronization among processes as a preprocessing for the production of a reduced global state transition graph to the transition of the process of the other side. When a branch is generated, only the transition of a process selected based on the priority that is previously set is selected, and a reduced global state transition graph generation device 2 generates a reduced global state transition graph from each process to which an auxiliary transition is added by the device 1. Since an auxiliary transition elimination device 3 eliminates the auxiliary transition as an after-processing it is possible to perform the branch cut processing without analyzing the information on a parallel program and also in a short time.

IPC: B63B59/10
Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To provide an underwater moving device to be well suitable for traveling on a vertical wall surface and reduce size and weight. SOLUTION: When thrust fans 10a and 10b are rotated, a differential pressure opening closing type check valve 40 is opened and water is injected to the outside and a device body 5 is moved to the belly side 4. By bringing a seal skirt 26 at the periphery of the opening of the belly side 4 into contact with a wall surface 25 in water, the interior of the device body 5 is brought into a negative pressure and an underwater moving device 1 is sucked on the wall surface 25. In this case, when a negative pressure at the inside of the device body 5 exceeds a given value, a differential switch 51 stops the thrust fans 10a and 10b, a differential pressure opening closing type check valve 40 is closed, and the interior of the device body 5 is kept at a negative pressure.  When a negative pressure at the interior of the device body 5 is reduced to a value lower than a given value, the differential pressure switch 51 restarts the thrust fans 10a and 10b, the differential pressure opening closing type check valve 40 is opened, and the degree of a negative pressure at the interior of the device body 5 is increased. When, with this state, a moving mechanism 11 is driven, the device body 5 is able to travel over the wall surface 25.

Filed: 1988-09-05
Abstract: PURPOSE:To average numbers of waiting times as a whole by measuring respective numbers of waiting times when output line numbers of each packet conflict with each other and outputting the data about the input having the largest number of waiting times. CONSTITUTION:Output line numbers outputted from the register 21 of each input buffer means 101-104 are inputted to the 1st comparing means 11 where whether the same output line number exists or not is checked. When one of output line numbers of inputs 2-4 is consistent with the output line number of an input 1, the inputs are inputted to the AND gate 25 of a priority measuring means 121. Outputs of priority measuring means 121-124 are inputted to the 2nd comparing means 13 by which each counter value is compared with another and the input having the smallest number of waiting times is kept waiting. Therefore, the number of waiting times of each input port is not leaned to one side, but averaged when a output line number conflicts (congests) with each other. As a result, the packet transferring efficiency can be improved.
