Abstract: A steering wheel for a vehicle includes spokes made of a flexible casing alloy by a molding process so that they integrally connect a boss and a steering wheel rim. Accordingly, the production of the steering wheel is facilitated.

Abstract: An energy absorbing apparatus for a steering wheel includes an energy absorbing portion or member disposed between a steering shaft and a steering wheel rim. The energy absorbing member is constituted by an annular relatively thin plate which surrounds the axis of the steering shaft. A portion of the energy absorbing member is bent in the plane orthogonal to the axis of the steering shaft, whereby the bent portion is deformed when a collision occurs, and the kinetic energy is thereby absorbed. The deformable bent portion is provided with a plurality of slits extending radially of the steering shaft and has embossed portions each defined between a pair of adjacent slits, whereby it is possible to control the absorption of any impact load and adjust the amount of kinetic energy which it is intended should be absorbed.

Abstract: A lock plates inserting machine and a method of automatically and mechanically inserting a plurality of lock plates into corresponding openings defined in the key cylinder. The lock plates inserting machine includes a key holder having a plurality of grooves corresponding to respective serrations of a key to be inserted. At least one key serrations detecting member having a key serrations detecting convex portion is inserted into one of the grooves of the key holder. At least one slide member is slidable upon pivotal movement of the key serrations detecting member and upon concave portions equal in number to the different sizes of the key serrations. A plurality of first push members corresponding to respective concave portions of the slide member are positioned so that a proper one of the first push members is inserted into its corresponding concave portion of the slide member in accordance with the slide members's position.

Abstract: A full automatic die casting machine including a fixed die, a movable die, a melting furnace and an injection cylinder. At least either one of the fixed die and the movable die is provided with a first recess for forming an article and second recess for forming an engageable portion on the article. The die casting machine further includes an article supporting device, a coating device for coating die lubricant on the first recess and the second recess, a finishing device, a packing device and a recycling device.

Abstract: A casting apparatus for casting a spherical metal lumps which includes a plurality of casting molds provided around an intermittent rotary member so as to radially outwardly extend from the rotary member, a control member to successively close the casting molds at an upper position and a position before the upper position in the rotational path of the casting molds and to open the casting molds at a lower position of the rotational path, and a molten metal pouring funnel provided at the upper position for pouring molten metal into the casting molds.

Abstract: A pre-heating assembly to be used for pre-heating ingots being transported to a melting furnace, which includes an inner cylinder constituting a main passage for exhaust gas discharged from a flue of the melting furnace, an outer cylinder which is positioned around the inner cylinder to leave a subsidiary passage for the exhaust gas between the two cylinders, an ingot supplying passage spirally provided along the outermost circumference of the inner cylinder, in which the ingots, each having a spherical configuration like a ball, roll down the passage in succession so that each ingot is pre-heated prior to its introduction into the melting furnace, and a connector support member, on which both cylinders are mounted and the bottom portion of the connector support member is coupled to the outlet of the flue.

Abstract: In a case for a small-sized motor, there are provided projections and convex portions in the cylindrical portion of the case for holding permanent magnets in the case without using any binding agent, springs or screws.

Abstract: A heat exchanger includes wall members forming a fluid passage therebetween and an inner fin formed of a sheet metal and disposed therein. The inner fin is formed with a plurality of corrugated projections whose side portions are twisted at a certain angle in a plane parallel to the sheet metal with respect to a direction transverse to a fluid flow.
