A power ratchet wrench including a yoke that is in sliding contact with opposing faces of a distal end bifurcated portion of the wrench housing, guide bushings fitted and fixed in the distal end bifurcated portion and inserted in the hole of the yoke to support the yoke, a spindle inserted in the yoke, and a protruding member that prevents the spindle from being pulled out. The spindle that turns a workpiece is supported by the guide bushings. The motion converter of the wrench includes a swing lever rotatable in a back-and-forth fashion in the wrench housing; and the engagement portion at one end of the swing lever engages a ball on an eccentric shaft of a speed-reduction assembly, and a cylindrical portion at another end of the swing lever is slidably engaged with a U-shaped groove of the yoke.

A half bearing constituting a cylindrical plain bearing for supporting a shaft for rotation when two of the half bearings are combined together. The half bearing has two circumferential ends each of which has a plurality of circumferential grooves without formation of any crush relief surface. The grooves extend substantially over an overall circumferential dimension of the half bearing and include portions located at both circumferential ends of the half bearing respectively. Each portion has a larger axially sectional area than the grooves formed in a portion of the half bearing mainly subjected to load during rotation of the shaft.

Microspherical sintered bodies of hydroxyapatite are prepared according to a new specific process wherein a suspension having hydroxyapatite microparticles dispersed in water or an organic solvent or a mixture of water and an organic solvent compatible therewith is atomized into a heating zone maintained above 500.degree. C. whereby spherical agglomerates of hydroxyapatite microparticles formed by drying and solidification of microdroplets of the suspension are sintered while the agglomerates are suspended in the heating zone. Microspherical sintered bodies of hydroxyapatite thus obtained, which may be modified by an optical heat treatment to adjust the surface area of the sintered body and growth of crystals therein, are useful in various fields of industry, for example, as a sorption agent in chromatographic separation.

An improved pneumatic impact imparting tool includes a follower which is slidably accommodated in a recess formed on the inner end part of a rotor in a pneumatic motor. The follower is formed with a projection for moving a ball around a cam face as it is rotated together with the rotor. When the ball reaches the peak of the cam face, the follower is displaced in the axial direction and enters a recess formed on the inner end part of an anvil and collides therein against stoppers formed in the recess. Thus, rotational movement of the rotor is transmitted to the anvil in the form of intermittent turning movement of the latter.

An improved pneumatic impact imparting tool includes a follower which is slidably accommodated in a recess formed on the inner end part of a rotor in a pneumatic motor. The follower is formed with a projection for allowing a ball to come in contact with a cam face as it is rotated together with the rotor. When the ball reaches the top of the cam face, the follower is displaced in the axial direction and enters a recess formed on the inner end part of an anvil to collide against stoppers in the recess. Thus, rotational movement of the rotor is transmitted to the anvil in the form of intermittent turning movement of the latter.

The present invention relates to a process for preparing a calcium-phosphorus-apatite, essentially characterized by admixing a single solvent of water or an organic solvent compatible with water or a mixed solvent of water with an organic solvent compatible with water with calcium and phosphorus compounds soluble in said single or mixed solvent to prepare a raw material solution, and atomizing the raw material solution into a flame or a heating zone for effecting a thermal decomposition reaction thereof to form a calcium-phosphorus-apatite; a calcium-phosphorus-apatite obtained by the process and having novel characteristics; and the use of the calcium-phosphorus-apatite as a chromatographic packing material.

A tool head is provided that can easily correct the shape of a tooth surface. Slot holes are formed in a main head body, that tilt either distally or proximately to the central axis of rotation (CAR) of the main head body. Concave tooth surface blades for cutting concave tooth surfaces are installed in the slot holes that tilt distally, and convex tooth surface blades for cutting convex tooth surfaces are formed in the slot holes that tilt proximately. By changing the amount that the concave or convex tooth surface blades protrude, the cutting portions of the concave or convex tooth surface blades are moved in either distal or proximate directions. By changing the distance from the CAR to the cutting portions in this manner, it is possible to correct the shape of the concave or convex tooth surfaces of a bevel gear.

A packaging pouch for packaging an absorbent article has a front, back and side faces. The side faces are folded between the front and back faces. The packaging pouch is rectangular in use. A sealing portion expanding in a transverse direction around the upper end of the packaging pouch, a side face portion that forms the side face of the package, and a top portion that forms the top face of the package by positioning between the sealing portion and the side face portion are formed. Moreover, perforations are formed in the top portion along a reference line extending in the transverse direction from one side edge of the packaging pouch to the other side edge of the packaging pouch. Handle members extending in the transverse direction from around one to the other side edge and are attached to the front back faces in the top portion below the perforations.

Disclosed herein is a photoelectric conversion element module including a plurality of photoelectric conversion elements between two base materials. Each of the photoelectric conversion elements is anchored to one of the base materials via an anchoring layer. The anchoring layer covers at least part of a sealing portion of each of the photoelectric conversion elements.
