Title: High frequency conducting current induction quenching method
Inventor: MUTO YASUO
IPC: C21D1/10
Filed: 1989-05-22
Abstract: PURPOSE:To execute high frequency conducting current induction quenching, which can form hardened layer having almost uniform depth on this surface and also prevent strain, by changing the shortest distance of a core arranged between shunts in a second conductor and surface to be quenched and changing the depth of hardened layer or strain quantity formed on the above surface. CONSTITUTION:The high frequency current is conducted to a first conductor 1 from a high frequency power source 5 and returned back to the power source 5 through the material 3 to be quenched and the second conductor 2. That is, a part of the high frequency current conducted to the conductor 2 flows bottom surface 2d of the conductor 2. During this, heating of the surface 3a to be quenched is executed with two currents of the high frequency current conducted on this surface 3a and the high frequency current induced on the surface 3a with the high frequency current conducted on the above bottom surface 2d. Then, after completing heating to the surface 3, cooling liquid is injected 2c on the surface 3a from each apace 24 in the shunts 21, 22 to complete the quenching. Further, on the surface 3a, as shown in the figures (b) and (c), the hardened layer 3b, where size (h) of the depth in the hardened layer 3b at center part in sectional face of the material 3 is almost equalized with the depth in the part except the center part, is formed.

Title: Data copy system between multiplexed auxiliary storage devices
Inventor: KAGAWA TETSUO
IPC: G06F11/20
Filed: 1991-05-31
Abstract: PURPOSE:To prevent even data whose writing is completed from being copied, and to shorten a data copying time by copying the data only of the divided part of a data area to which a writing request is issued after a power supply is restored between auxiliary storage devices. CONSTITUTION:A central processing unit 1 judges whether or not the number of writing requests preserved in a back-up memory 3 is '0' by each divided area of the data area after the power supply is restored. At the time of judging that the number of the writing requests is '0', the central processing unit 1 doesn't copy the data of the divided part, and judges whether or not the number of the writing requests to the entire divided parts preserved in the back-up memory 3 is checked. When it is not checked, the central processing unit 1 repeats the check, and when the check is ended, the central processing unit 1 operates the next execution processing. On the other hand, at the time of judging that the number of the writing requests to the divided parts is not '0', the central processing unit 1 issues the request of the data copy only of the divided part to which the number of the writing requests it not '0' between the auxiliary storage devices to the auxiliary storage devices. Thus, the copying time can be shortened.

Title: Sample introducing probe in mass spectrograph
Inventor: KOBAYASHI TATSUJI
IPC: H01J49/04
Filed: 1988-05-27
Abstract: PURPOSE:To make decomposing cleaning of a probe needless for easy handling by supporting a male screw body on a collar of a sample leading-in probe with thin supporting rods of a low thermal conductivity material. CONSTITUTION:A male screw body 12 is not directly fixed to a collar 11 being instead supported with four thin supporting rods from 21a to 21d of a material such as the low thermal conductivity stainless steel. The screw 12 is formed of a material having bad thermal conductivity and a gap is made on the window part of a transfer tube 19 so that the screw 12 may not directly touch the transfer tube 19. In this way, the heat of a holder 15 is not transferred to the collar 11 so as to prevent temperature rise of the transfer tube 19, a solvent component is not vaporized halfway but vaporized immediately before a porous member 14 and a sample component is not stuck to the transfer tube 19 instead for being vaporized after reaching the member 14. Thereby the transfer tube 19 is prevented from being heated and the solvent component in a sample liquid is prevented from being vaporized halfway to stick the sample component to the transfer tube for being stopped up so that a probe 9 is not needed to be decomposed for cleaning so as to extremely simplify handling.

Abstract: PURPOSE: To exercise highly precise control even in occurrence of a disturbance, by exercising control over a system while forecasting fluctuations of the system.  
     CONSTITUTION: A nuclear-fusion experimental device is unable to cope with complicate motion of plasma only in programmed process. This complicate motion acts upon the process as a disturbance. Condition judgement part 5 receives a coil voltage and electric current from coil 3 and fetches signals of a plasma current, density, position, shape, etc., from plasma 4. On the basis of those input signal, whether the motion can be regarded as a disturbance is judged and according to the result, the fluctuation extent is forecasted on the basis of various fluctuation data due to the right previous disturbance to exercise control. For this purpose, the frequency and voltage of the AC electric power source are not controlled directly and the output of thyristor phase controller 14 influenced by them is controlled right previously.
