Title: Manufacture of impeller
Inventor: SUGANO MASAYOSHI
IPC: F04D29/28
Filed: 1978-12-08
Abstract: PURPOSE: To make the finish processing of the wave breaking portions of a blade and side plate by assembling the impeller elements with a fan-type main plate material, side plate material and blade; and welding the elements together after collecting them in a shape of a circle.  
     CONSTITUTION: An imperller is completed by assembling impeller elements 10 having a fan shape from which the impeller is to be formed, with the use of the fan- shaped main plate material 11, fan-shaped side plate material 12 and blade 13, and by collecting the impeller elements 10 to form a circle so that the elements are welded together. The elements 10 are formed by those which are cut out of a block material; precisely molded; and electrolytically processed. Otherwise, they are joined by welding or made by a combination of welding and molding, depending on the size and shape required. Consequently, the conventional method of processing in which the wave breaking portions of the blade and side plate becomes unnecessary, besides the shrinkage of blade width caused by the distortion produced at the time of welding does not occur. Thus, it becomes easier to produce a highly precise impeller for use in high speed rotation.

IPC: H01J49/14
Filed: 1982-08-31
Abstract: PURPOSE:To enable the reflux of cooling water to an ion source and fully exhibit easiness of obtaining the information of molecular weight that is an advantage of a chemical ionization method by applying the potential that corresponds to ion accleration voltage to an injection slit and an analytical section so as to set the ion source to ground potential. CONSTITUTION:Gas such as methane, isobutane, and ammonia for ionization reaction is supplied to an ionization chamber 11 from a reagent gas supply port 5 and this reagent gas is changed into an ion due to electron bombardment and ion molecular reaction by making an electron generated from a hot cathode 7 incident from an electron incident hole 6 to this gas. In addition, the induced sample gas is ionized when this ion reacts with the sample gas. In this case, since the potential that corresponds to the ion pressurized voltage is applied to an injection slit 2 and an analytical section 3 from a power supply 4, an ion source 1 is set to ground potential E and the reflux of cooling water is enabled. As a result, the temperature of the ion source can be reduced by making the cooling water flow back from an entrance 9 to the ionization chamber 11 and to an exit 10.

Title: Superconductor
Inventor: SHINOHARA JOSHI
IPC: H01B12/06
Filed: 1989-06-16
Abstract: PURPOSE:To achieve safety in temperature control aspect and to thin the diame ter by forming a stabilizing layer of a superconductor material on a fiber of a superconductor material having its own transition temperature and making the transition temperature of the layer higher than that of the fiber. CONSTITUTION:A fiber 1 of a conventional low transition temperature supercon ductor 1 is coated with a stabilizing layer 12 of a superconductor material 11 having higher transition temperature than that of the fiber 1. Further, a second stabilizing layer 13 of a cupper material is formed on the outside of the stabilizing layer 12. When local temperature rising occurs due to cooling failure, quenching is caused at once. That is, superconductive conduction of the fiber 1 is lost and the resistance of the fiber rises sharply. At that time, the stabilizing layer 12 of the superconductor 11 is still in superconductive state, and its current density J is the same as that of the fiber 1 in the superconductive condition, and therefore, large current at a normal operational time flows safety as it does and is not extended to be a large accident such as high heat generation.

Title: Information processing system, its control method information processor and its control method
Inventor: INOUE ATSUSHI
IPC: G06F12/00
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To decrease the traffic for the access to an object and to attain an effective access to the object by outputting the information on a name space to a host serving as a command issuer for management of the object to be accessed. SOLUTION: The directory information stored in a directory which is managing an object to be accessed is returned to a host D that issued a path name together with the solution result of the path name. When the host D issued a path name /b/f/n, for example, and this name is solved, the directory information stored in a directory (f) is managed by the host D. Thereby, if the host D accesses a file following the directory (f), the host D can internally solve the path name without having communication with another host. Furthermore, it is not necessary to transfer the directory contents under solution and accordingly the traffic can be decreased.

Abstract: PURPOSE:To prevent an interpolation stopping time from being generated by automatically adjusting interpolation speed so as not to set the amount of data of execution format stored in a memory at a value less than a prescribed value. CONSTITUTION:An execution data block number adding part 9 adds '1' on the number of blocks of the data SC of execution format from an execution data generating part 3, and stores it in the memory 8B. Meanwhile, an execution data subtracting part 10 subtracts '1' from the number of blocks of the execution data stored in the memory 8B. And an interpolation speed command generating part 4 finds an interpolation speed command by the data SM of execution format from the subtracting part 10, and outputs it to an interpolation speed command change control part 11. The control part 11 reads out the number SK of blocks of the execution data stored in the memory 8B, and compares the number with a reference value. When it is less than the reference value, i.e. when the stopping time of an interpolating time is generated, the interpolation speed is adjusted automatically.
