Inventor: MATSUDA KENJI
IPC: B22F9/10
Filed: 1985-09-20
Abstract: PURPOSE:To develop metallic powder as a new stock for powder metallurgy having excellent characteristics by quickly cooling a molten alloy of a crystallization or precipitation type by a twin roll method, etc. to thin sheets, laminating the sheets and sintering the laminates, then working the sintered alloy to an electrode and forming the powder by a rotating electrode method using such electrode. CONSTITUTION:The crystallization or precipitation type alloy such as Al-8Cr alloy or Al-13Si alloy is melted in an inert gaseous atmosphere of Ar, etc. in a high-frequency induction heating furnace, etc. The molten metal is quickly cooled by a twin roll method or single roll method to produce the thin sheets of the Al alloy solutionized with Cr and Si. Plural sheets of such thin Al alloy are laminated and compressed, then the laminates are pressurized and sintered in a gaseous Ar atmosphere; at the same time the solid soln. phase is finely precipitated as the compd. of Al-Cr and Al-Si. Such sintered body is machined and is worked to a round bar- shaped electrode. The electrode is used as an electrode for a rotating electrode type metallic powder device. The new metallic powder stock having the excellent characteristic as the raw material for powder metallurgy is thus produced.

Title: Multicarrier transmission system and reception equipment
Inventor: TAKAHATA FUMIO
IPC: H04J11/00
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To estimate the frequency error of local transmitter output between transmission and reception or frequency error caused by Doppler fluctuation and to correct that error on the side of demodulation in a multicarrier transmission system. SOLUTION: A reception pilot symbol 54a is supplied through a switch 12 to a multiplier 20 and multiplied with a demodulation side pilot symbol 56c outputted from a parallel/serial converting part 23. Thus, convolution operation is a frequency area can be calculated as multiplication in a time area. In this case, the reception pilot symbol 54a and demodulation side pilot symbol 56c are set based on a code stream such as M sequence improved in self-correlation characteristics. Thus, the output signal of the multiplier 20 has a sharp peak in the frequency area corresponding to the frequency error and a peak detecting part 26 detects this peak position. Afterwards, an NCO 29 generates a complex signal 54g corresponding to the frequency error and this signal is multiplied with a data symbol by a multiplier 14.  Thus, the frequency error is appropriately corrected on the side of demodulation.
