摘要:
A reduction gearing device for automobile accessory motor comprises first and second worms coaxially formed on a worm shaft in different thread directions, a pair of first and second intermediate gears each composed of two gear members, with one gear of each pair being engaged with a respective worm, and a common output gear engaged with the other gear member of each of the intermediate gears. The engagement of one intermediate gear with the first worm is in phase with the engagement of the other intermediate gear with the second worm while the engagement of one intermediate gear with the common output gear is in phase with the engagement of the other intermediate gear with the common output gear.

A method of making a connecting rod for an internal combustion engine which includes shaping a bundle of unidirectional inorganic fibers, placing the bundle into a shaping container and heating it partially in order to fuse the fibers to each other. The partially fused bundle is positioned in a mold in such a manner to produce an extra gap for a predetermined machining allowance between the bundles and cavities. A molten light metal alloy is squeeze cast into the mold under high pressure, i.e., 500-2000 kg/cm.sup.3, forming a matrix annular layer around the bundle. The rod portion of the obtained connecting rod is machined to remove defects in casting, such as a fatigue crack, a blow-hole or mixing of oxidated substances and takes the shape of a circular or elliptical cross-section.

A temperature detecting device which comprises an electrical bridge circuit including four arms, a temperature responsive resistance contained in one of the arms, a resistance type potential divider having at least one intermediate terminal which represents an output terminal of the network, and switching means connected across two power source terminals thereof for inverting the connection of the potential divider in accordance with a temperature state, positive or negative, which is detected by said device, the respective divided portion divided by the intermediate terminal forming two arms of the network.
摘要:
A motorcycle or the like is provided with parallel telescoping tubes forming part of an inclined front fork assembly straddling the front wheel. The wheel is mounted for rotation on said assembly about an axis spaced rearward of the telescoping tubes to reduce friction forces between them. The lower ends of the upper tubes are tapered to promote the formation of oil wedges for maintaining an oil film between the telescoping parts. Also, the fork assembly is mounted on the frame for pivotal movement about an inclined axis diverging with respect to a plane containing the axes of the telescoping tubes.
