Title: Method for synthesizing diamond
Inventor: YOSHIDA KATSUTO
IPC: C01B31/06
Filed: 1988-03-08
Abstract: PURPOSE:To enable large size diamond grains to be obtained at a low cost in a synthesis of diamond by film-growth method, by arranging diamond seed crystals so that a face of each seed crystal is brought into contact with one of solvent metal blocks which are set separately from one another. CONSTITUTION:Diamonds are synthesized by a film-growth method by the use of a reaction system consisting of diamond seed crystals 1, a carbon source 3 and solvent metal 2 (e.g., simple substance of a transition metal such as Fe, Co, Ni, Cr, Mn or Pt, or their alloy). In this reaction system, one or more blocks 2 of the solvent metal are set separately from one another, and the diamond seed crystals are arranged so that a face of each crystal 1 is brought into contact with a block 2 of the solvent metal. Furthermore, separation matters 4 and 5 (e.g., NaCl or MgO) are arranged at the top and bottom of the reaction system. It is possible, as a result, to synthesize high quality diamonds of such a large grain size as 1-2mm at a low cost.

Title: Moving blade of steam turbine
Inventor: NAKABASHI MASAKO
IPC: C22C19/07
Filed: 1983-03-30
Abstract: PURPOSE:To obtain a blade that is excellent in strength at the joined section and will not be formed with an embrittled layer on the blade base due to the melting, by joining a Co base alloy, which is excellent in resistance to cavitation erosion, to the forward edge of the forward end section of the blade using the diffusion bonding process. CONSTITUTION:The last stage moving blades of a steam turbine will be wasted due to cavitation erosion by high speed impingement of condensed water droplets contained in steam. To overcome this, an erosion shield (a) of a stellite alloy containing about 50% Co that is excellent in resistance to cavitation erosion is joined to a 12-Cr base steel of the blade base (b) at the forward edge of the forward end section of the blade where wastage can occur more thereby protecting the forward edge. The diffusion bonding technique is used to join the shield (a) to the vane base (b). Therefore, a vane that is excellent in strength at the joined section and will not be formed with an embrittled layer due to the melting of the vane base (b).

Abstract: PURPOSE: To obtain a magnetic tape having high quality by executing surface polishing of a magnetic layer in succession to formation of the magnetic layer by vacuum vapor deposition, thereby entirely obviating the adhesion of worn powder on the magnetic tape wound around a take-up hub. CONSTITUTION: The magnetic layer is formed on a base film 2A traveling on a cooling roller 5 within a vacuum chamber 1 to be a magnetic tape blank 2B. The magnetic layer is formed out of a magnetic metal 9 in a crucible 8 which is evaporated to fly by irradiation with the electron beam from an electron gun 10 and is deposited on the base film. The magnetic tape blank 2B is successively subjected to surface polishing of the magnetic layer by a polishing device 20 to be the magnetic tape 2C. The surface polishing is executed by a lapping tape 19. The microprojections of the magnetic layer prior to the surface polishing are removed by the surface polishing. The worn powder generated at this time is captured by the lapping tape.  Even if the worn powder fails to be captured by the lapping tape and tends to partly suspend in the vacuum chamber, this worn powder is discharged outside by a discharge pipe 22 connected to a casing 21.
