Title: Welding method for metallic chromium compacts
Inventor: MATSUDA FUKUHISA
IPC: B23K15/00
Filed: 1990-02-28
Abstract: PURPOSE:To obtain a satisfactory weld bead by using the metallic chromium compacts obtained by compacting metallic chromium powder containing specific wt.% Al and Si, preheating these at the specific temperature to perform electron beam welding thereon. CONSTITUTION:The metallic chromium compacts 1 and 2 are subjected to electron beam welding at a weld zone. At that time, the metallic chromium compacts 1 and 2 having Al and/or Si content of <=0.017wt.% are used. These are preheated at the range of 300-400 deg.C and welded. Conditions of the electron beam welding method are not limited especially and welding is performed by the usual method, for instance, in an atmosphere such as in a vacuum, in an inert atmosphere and in air. Consequently, the occurrence of cracking on the welded zone can be obviated.

IPC: G01N30/88
Filed: 1994-03-16
Abstract: PURPOSE:To efficiently reduce dinitroallene (DNPAH) online by reducing the dinitroallene to diaminoallene (DAPAH) by a metal catalyst column, separating it and then detecting it. CONSTITUTION:When extracted liquid, etc., of atmospheric dust is, for example, analyzed, a moving phase of a moving phase reservoir 9 is sent to a metal catalyst colunm 7, a separate column 8 by a moving phase sending pump 1, set to a steady state, and a sample is then introduced from a sample introducing unit 3. Dinitroallene (DNPAH) in the sample is reduced to diaminoallene (DAPAH) by the column 7, separated by the column 8, and eluated. This eluate is mixed with reaction reagent steadily sent by a reaction solution pump 2 by a reactor 4 to emit a light. This is detected by a chemical emission detector 5, its intensity is converted to an electric signal, and quantitatively calculated by a data processor 6. Thus, an infinitesimal amount of the DNPAH can be accurately measured with high sensitivity without complicated pretreatment.

Title: Magnetic recording medium substrate
Inventor: TOMITA ETSUKO
IPC: G11B5/82
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To easily optimize the annular projection by maintaining a 'contact area parameter' of a medium substrate within the range smaller than the 'contact area parameter criterion value' in which a frictional vibration between slider and medium substrate rapidly increases. SOLUTION: An annular projection is provided within a contact start stop zone of a magnetic storage medium substrate on which a slider takes off and makes landing. When the annular projection is formed annularly, the 'contact area parameter criterion value' has a particular value corresponding to the annular diameter. The contact area of slider is related to the absorption phenomenon between the slider and medium substrate, giving an influence on the sliding phenomenon of slider during the CSS operation. The contact area of slider can be expressed using the 'contact area parameter' of the medium substrate expressed with (annular circumference length of annular projection × annular projection density per unit area of medium substrate × radius of curvature of the annular projection end)0.5.  When the contact area parameter is smaller than the contact area parameter criterion value, friction vibration becomes small.

Title: Electro-processing control method
Inventor: SAITOU NAGAO
IPC: B23H7/28
Filed: 1978-04-20
Abstract: PURPOSE:To easily remove residual cores and streaks formed on the surfaces of a workpiece by giving an eccentric motion to an electrode coupled with the control of the main shaft feeding mechanism, as well as giving a swing motion on an arc to an electrode when the electrode has slopes. CONSTITUTION:An eccentric motion 6, centering on the reference points 0, neither rotates an electrode 5 made of a cornered material, nor affects it in the X axis and  the Y axis directions. A swing motion 7 on the X axis and another swing motion 8  on the Y axis are controlled to move back and forth along arcs on the X-Z plane and the Y-Z plane respectively. Therefore, when a workpiece 9 is processed by the electrode which has slopes on its sides, the eccentric motion itself cannot eliminate residual streaks 10 due to steps on the cornered material. This necessitate the swing motions 7 and 8 to be given to the electrode 5.
