Title: Hot working method for powder of high speed steel
Inventor: KAWAI NOBUYASU
IPC: B22F3/24
Filed: 1980-03-03
Abstract: PURPOSE: To save forging process and apply hot working under lessened energy by hot rolling the powder high speed steel sintered compactly by an HIP method by specifying the relations among rolling ratios, temperatures, and reduction of area.  
     CONSTITUTION: High speed steel power is HIP treated, whereby a compactly sintered body is obtained. This powder high speed steel billet is hot rolled without forging. This hot rolling is accomplished at 5W50% reduction of area per pass at 1,000W1,200°C in a region of ≤4 rolling ratios and at 10W75% reduction of area per pass at ≥800°C in a region of ≤4 rolling ratios. This method saves  forging prior to forging by performing rolling under gentle rolling conditions up to  4 rolling ratio at which there is no more segregation of deposit to grain boundary  and performs working to a required size by the hot rolling alone. Hence, the  reduction in cost and the considerable improvement in productivity are achieved.

Filed: 1994-02-24
Abstract: PURPOSE:To carry out micro area elemental analysis at an atom level without carrying out any special sample preparation by impressing voltage onto a probe brought close to a sample surface so as to ionize atoms on the sample surface. CONSTITUTION:A probe, which is clean at an atom level and is provided with a stable mini probe at a tip, is brought close to the surface of a solid sample at a distance of approximately 1mm, and positive or negative voltage is impressed onto the probe. In this way, atoms on the solid sample surface can be extracted in ionized condition. In this process, a probe used for a scanning tunnel microscope can be directly used for the probe, and Ag, W, and the like are desirable for its material. As to the impressed voltage, negative (positive) voltage of 1-10V is impressed for positively (negatively) ionizing the sample atoms. The optimum value depends on the material of the solid sample and the probe and the distance between them, and continuos and pulsative impression and ionization of an optional area by scanning of the probe can be carried out. Then, generated ions are detected by a highly sensitive mass analysis method so as to be fixed.

Title: Catalyst combustion device
Inventor: SHIBATA TSUNEO
IPC: F23D14/18
Filed: 1981-02-25
Abstract: PURPOSE:To make it possible to start ignition correctly by a method wherein a movable wing is moved in response to the operation of an ignition heater so that the supply of a gas mixture is concentrated on a part of a catalyst coming into contact with the ignition heater only at the time of ignition. CONSTITUTION:In combustion, when a button 11 of an ignition switch 4 is operated to reach an ignition position, an electric current flows through the ignition heater 3 and as soon as the part 2' of the catalyst 2 which is in contact with the ignition heater 3 is heated, the gas mixture is injected from the nozzle 5. In this case, as an operation rod 10 of the ignition switch 4 moves in the A direction, the movable wing 7 moves in the B direction. Consequently, the gas mixture is supplied mainly on the part 2' of the catalyst 2 so that the ignition efficiency of the ignition heater 3 is improved. Further, when the button 11 is set at an ordinary combustion position, the movable wing 7 assumes a position parallel to a combustion cylinder 1 and the gas mixture is supplied uniformly over the whole of the catalyst 2 so that the catalyst 2 burns in its entirety.

Title: Method of detecting megnetic flux component of ac rotary machine
Inventor: NOMURA TOSHIHIRO
IPC: G01R33/02
Filed: 1978-03-10
Abstract: PURPOSE: To improve the accuracy of detecting magnetic flux at low frequency by applying the positive peak value of estimated magnetic flux to one input of a comparator and feeding back the output of the comparator to an integrator.  
     CONSTITUTION: Estimated positive peak magnetic flux value +ϕR is applied to one input of a comparator 12 and magnetic flux value -ϕR amplified by an amplifier 11 is applied to the other input of the comparator 12. If the output ϕ of the integrator 10 is within the estimated peak values ±ϕR, the output of the comparator 12 is fluctuated toward minus side and the output of a comparator 13 is fluctuated toward plus side. If the resistances R 5 , R 6  are set equal, e becomes zero. If the accuracy of the comparator 10 is finely adjusted, it can accurately calculate even at low frequency. If the output ϕ exceeds -ϕR, the output of the comparator 12 is fluctuated toward the plus side and the e is fluctuated toward the plus side to operate to reduce the output ϕ via the R 8 . If the output ϕ is lowered from -ϕR, the e is similarly fluctuated toward minus side so as to return around the output ϕ as a center. Thus, it can accurately detect the magnetic flux to low frequency.
