IPC: G01B21/26
Filed: 1999-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a wheel alignment adjusting device capable of accurately positioning a mount part for mounting wheels of a vehicle. SOLUTION: Front and rear tire drivers 118 of a vehicular width direction left side are fixed on a mount base 18, front and rear tire drivers 118 of a vehicular width direction right side are attached on a first slide base 34R, and the first slide base 34R is constituted so as to move in the vehicular width direction in regard to the mount base 18.

Title: Production of injected and sintered body of powder
Inventor: MIYAKE MASATO
IPC: B22F3/10
Filed: 1991-07-31
Abstract: PURPOSE:To rapidly remove a binder from a compact while ensuring strength without causing defects and to produce an injection-compacted and sintered body. CONSTITUTION:A binder used in an injection compacting process is composed of 1st and 2nd binder components. Both the 1st and 2nd binder components have powder bonding functions but do not dissolve in the same solvent. In a binder removing process, the 1st binder component is first extracted with a solvent and then the 2nd binder component is thermally decomposed and vaporized. Since strength is imparted to the resulting compact by the bonding functions of the binder components, the compact is made easy to handle and breakage is prevented. Since the binder is removed in two stages, deformation and defects are not caused and the binder can rapidly be removed.
