Title: Sintering method
Inventor: FUJIWARA YASUYUKI
IPC: B22F5/12
Filed: 1986-10-27
Abstract: PURPOSE:To suppress the dimensional distortion of parts after sintering to a low level by supporting the outside peripheral part of the rib of the cylindrical sintered parts having an H-shaped section by a cylindrical jig having a through- hole at the base and sintering said parts. CONSTITUTION:The outside peripheral part of the rib part 3 of the cylindrical sintered parts having the H-shaped section; for example, a cam pulley 2 is supported by the top end part of the sintering jig 1 which is of a cylindrical shape, is opened at the top surface and has the through-hole 4 at the center of the base. Such jig 1 is placed on a meshed belt 8 in a sintering furnace and the parts are subjected to sintering. The jig 1 is constituted of Al2O3-SiO2- MgO, etc., and is formed with a taper 5 at the top end part thereof to avert the direct contact of the round part 7 where the tooth part 6 of the pulley 2 and the rib 3 intersect with the top end of the jig 1. The behavior during sintering is stabilized and the generation of the distortion in the sintered parts is suppressed by the above-mentioned method.

Title: Power transmitting device
Inventor: KURIHARA SAKUO
IPC: B60K17/344
Filed: 1984-12-06
Abstract: PURPOSE:To improve the readiness of an assembly to a vehicle by enabling a device itself to connect or disconnect a rear wheel driving system to or from rear wheel axles separately from a lever operating force of a transfer gear when a change-over between a two wheel drive and a four wheel drive is effected. CONSTITUTION:Change-over to a four wheel drive allows a drive gear to mesh with a ring gear 13 permitting a case 7 to rotate. This causes cases 7 and 9 and a cone plate 51 to rotate relatively permitting a friction 43 to be subjected to a frictional force from a cone surface 51a. The rotation of the friction plate 43 allows a cam late 41 to be subjected to a resisting force. This causes a traveling body 17 to be energized by a compression spring 27 and to move to the left following the movement of an operating arm. This resultantly, allows a gear 17a and a gear 17b to start meshing simultaneously with a connecting gear 33 and a connecting gear 35 respectively permitting both a right and left axles to be rotated as an integral unit.

IPC: G01M11/02
Filed: 1989-10-02
Abstract: PURPOSE:To analyze interference fringes without any lateral shift in the position of an image on a wave front to be measured by providing a means which slants the traveling direction of object luminous flux to an optical axis and a means which sets the position where the object luminous flux slants and an opening in conjugate relation. CONSTITUTION:On a surface 22b on the bisector 22c of a right angled prism 22, an image of the opening 5 is formed (intermediate image formation) through a reduction optical system 12R. When the prism 22 is rotated on an axis 22s by an extremely small angle, the image of the position of the opening 5 is obtained on the image pickup surface 26a of a TV camera 26 through the optical system 12R at an extremely fine angle to luminous flux (reference luminous flux) passed through an enlargement optical system 12E to obtain tilt fringes, which are analyzed to measure a spherical aberration with high accuracy. When the prism 22 is rotated at this time, the intermediate image formation surface 22b is at a fixed point, so the position relation between the position (wave front to be measured) in conjugate relation with the surface 22b and the surface 26a (interference surface) is not effected by the rotation of the prism 22 at all. Therefore, the image of the position of the prism 22 at all. Therefore, the image of the position of the opening 5 formed on the surface 26a does not shift laterally in position and measurement is accurately taken.
