<<１級／機械工学>>問１[0003]

An endless conveyer belt linked in chainlike fashion is used to convey metal products orthe like being treated at high temperatures in a hot furnace.

The conveyer belt is formed of many

chains or spirals, linked by chain rods formed of heat-resistant steel wire material.

However, theflexural strength of this material under an atmosphere of 1,000 - 1,200˚C is a mere 3 kg per square
mm maximum, so the rods may become deformed in a short time.

This can cause unevenness inthe shearing force acting on the linkages of the rods with the chains or spirals, with great shearing
force being locally concentrated, which can result in the chains or spirals breaking, the belt snaking,and ultimately rendering the conveyer useless.
[0004]

While there is known a conveyer belt using carbon fiber-reinforced carbon of which thestrength at up to 2,500˚C tends to exceed that at room temperature, usage in an acidic atmospherewhich would react with carbon is disadvantageous.
[0005]

Circulating the conveyer belt through the furnace subjects the rods, assembled in thetransverse direction as to the travel direction of the belt, to particularly high tensile force, i.e.
shearing force approximately perpendicular to the rods, so shearing strength of the rods
approximately perpendicular to the longitudinal direction thereof must be particularly ensured.
問２[0039]

While the rotary valve according to the present invention will be described below by wayof an example in which the same is disposed in a lead air flow path of a stratified scavenging
two-cycle engine, this rotary valve is not restricted to this application, and may be used as a fluid
control valve disposed between fluid flow paths. Moreover, fluid which this rotary valve cancontrol is not restricted to air; rather, flow rate and the like of various fluids such as liquids andgasses can be controlled. Accordingly, the present invention is not restricted to the embodimentdescribed hereinafter, and various modifications can be made.
[0040]

With a stratified scavenging two-cycle engine 2, a piston 3 is slidably fit within a cylinder

2 mounted on a crankcase 6.

A crankshaft 8 rotatably attached to the crankcase 6 is linked to one

end of a crank 9 rotatably borne within a crank chamber 7, and is also linked to the piston 3 by aconnecting rod 4.

Upon an air-fuel mixture compressed in a cylinder chamber C being ignited at

top dead center of the piston 3 by a spark plug 5 attached above the cylinder 2, the air-fuel mixture
explodes, pushing the piston 3 downwards.
