Title: Method for preventing deformation of sintered compact
Inventor: FUJISAWA KAZUO
IPC: F27D3/12
Filed: 1994-04-08
Abstract: PURPOSE:To prevent the deformation of the compact while being sintered at the time of sintering the compact by powder metallargical processing by placing the compact on globular or crushed stone-shaped ceramic powder. CONSTITUTION:A metal powder material is pressed and compacted by powder metallargical processing to form the compact with the complicated shape which is sintered. In this case, the compact is placed when sintered on a globular or crushed stone-shaped ceramic powder of alumina, zirconia, etc., having an appropriate thickness conforming to the supported face of the compact. Consequently, since every part of the compact is uniformly supported and sintered, the soft compact is not deformed by gravity during sintering, a sintered compact excellent in dimensional accuracy is obtained, and the yield lowering of the sintered product caused by the deformation is suppressed.

IPC: G01M7/00
Filed: 1980-05-31
Abstract: PURPOSE:To make the oscillating circuit of both systems to the same constitution completely, by enabling to produce two output signals in phase synchronism individually and at the some time through the use of two PLL ocillators. CONSTITUTION:An output signal of a voltage controlled oscillator VCO21 is fed back to a phase detector 22 and it is in phase comparison with the output signal of a VCO24. The output of the phase detector 22 is fed to the VCO21 via an LPF23 to control the oscillating frequency. On the other hand, the output of the VCO24 is fed back to a phase comparator 25 and it is compared for the phase with the output signal of the VCO21, and the output of the phase comparator 25 is converted into a DC signal via an LPF26 to control the frequency of the VCO24. Thus, if the characteristics of two PLL oscillators are equal, the oscillating frequency of the VCOs 21 and 24 is converged to (f1+DELTAf1/2) respectively and finally. Thus, independent signals having the frequencies of f1+DELTAf1 and f1 can be obtained from the terminals No.1 and No.2, respectively.
