Title: Production of sintered part
Inventor: FUJITA ISAO
IPC: B22F5/00
Filed: 1991-09-25
Abstract: PURPOSE:To increase the mechanical strength and to uniformize the internal hardness of a sintered part by adding C and a forming lubricant to a composite alloy steel powder of specified composition, sintering the admixture and then continuously cooling the sintered compact. CONSTITUTION:From 0.6 to 0.9wt.% C and a forming lubricant are added to a composite alloy steel powder consisting of 4.0-6.0% Ni, 1.0-2.0% Cu, 0.4-0.6% Mo and the balance Fe. The mixed powder is placed in a die and compacted to >=7.0g/cm<3> density, and the compact is sintered at 1250-1300 deg.C. The sintered compact is continuously cooled at a rate of about 5-20 deg.C/min to form a mixed structure of martensite and bainite. Consequently, heat treatment after sintering is dispensed with, and a high-hardness product excellent in tensile strength and impact value and having uniform internal hardness is obtained.

IPC: H01B19/00
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a combined organic insulator, preventing the occurrence of burrs. SOLUTION: The method for manufacturing a combined organic insulator comprises solidifying liquid organic polymer material onto the outer periphery of an insulating core 4 several times in sequence in the longitudinal direction of the insulating core 4 by using small molds A, B to form an insulating coating 15 on the outer periphery of the insulating core 4. A liquid leakage preventive protrusion 6 is provided at the rear end of the previous insulating coating 15 to prevent the liquid leakage of the liquid organic polymer material during forming the following insulating coating. The liquid leakage preventive protrusion 6, provided at the rear end of the insulating coating 15 previously solidified, gives the effect of an O-ring during solidifying the following insulating coating, inhibiting liquid leakage and preventing the occurrence of burrs.  The liquid leakage preventive protrusion 6 is free of deterioration because it is used once for liquid leakage prevention and free from troublesome management and replacement like that of the O-ring.

Title: Tuning fork-type piezoelectric vibrator
Inventor: SUZUKI HAJIME
IPC: G01N11/16
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To simultaneously measure physical property values of a viscosity and a density of a liquid highly accurately with the use of a tuning fork vibrator, by separating a vibrating part to a fixed part and a main body part via a slit extending in a sectional direction and bonding a piezoelectric body to the main body part. SOLUTION: Two vibrating parts 12 are coupled at a base part 11, thereby forming a tuning fork vibrator of a U-shaped cross section. Two slits 13 are cut in each vibrating part 12 at both sides in a breadthwise direction to extend in a sectional direction. A main body part 16 and two fixed parts 18 are integrally formed. Piezoelectric bodies 14, 15 are bonded to the vicinity of the base part 11 of the main body part 16. Only the main body part 16 vibrates. A liquid enters also the slits 13, and therefore a viscous resistance of the liquid acts to the main body part 16 by the fixed parts 18. A size of the viscous resistance is proportional to a velocity gradient of the liquid in touch with a vibrating face. A constant of the proportion becomes a viscosity of the liquid.  A sensor that can measure a viscosity and a density of a liquid at the same time is obtained with the use of a system detecting a vibration frequency and an effective value of a secondary output voltage of the tuning fork vibrator.

And the distance is set to coincide with the buckling deformation at the maximum loading capacity of the steel pipe column. And hence, only the deforming performance can be increased without increase of the loading capacity of the steel pipe column 1, after the buckled pipe column has come to contact with the reinforcing steel pipe 2.
