A method for manufacturing a cylinder having scavenging passages for a two-cycle internal combustion engine is disclosed which comprises the steps of forming bulged portions protruded radially outwardly in a portion of a cylindrical liner, and surrounding the liner by casting through a high pressure diecast method, thereby form a main part of the cylinder.
摘要:
Disclosed is a two-cycle internal combustion engine including a protruding edge portion formed in a section of a lower side surface of an intake port which is adjacent to a pre-compression chamber of a cylinder. This protruding edge portion serves to deflect air-fuel mixture introduced into the pre-compression chamber through the intake port so as to direct it to a bearing portion provided between a piston and a connecting rod. Further, a cut-in groove is formed in the protruding edge section and is adapted to allow any liquid remaining in the intake port to flow into the pre-comparison chamber.

摘要:
The present invention provides an information transmission apparatus and method for an information transmission system where encrypted information comprised of a plurality of information units each hierarchically encrypted and multiplexed to each other is communicated between at least two parties, wherein the information is being encrypted for transmission. The information transmission system is constructed by a transmitting unit and a receiving unit.
摘要:
An exhaust muffler of this invention is constituted of a muffler main body having an opening, a muffler cover closing this opening of said muffler main body and being capable of attachment and removal, a partition separating said muffler main body and said muffler cover, and a long exhaust extension pass formed by combination of said partition and said muffler cover and extending by meandering in said muffler cover. On said partition, a communicating hole is provided to communicate between said muffler main body side and said muffler cover side. A catalyst is provided on the surface of said partition facing said muffler main body to purify exhaust gas. Thus, exhaust gas introduced into said muffler main body flows into the space formed by said muffler cover through said communicating hole after purified by said catalyst. This exhaust gas passes meandering through said exhaust extension pass during which exhaust gas is sufficiently cooled down and then discharged into atmosphere.

A muffler for internal combustion engines is formed of vertically separable body sections so that the sound absorbing and filter members may be accessed easily for replacement and/or cleaning.
摘要:
A chrominance signal reproducing circuit reproduces a chrominance signal with reduced crosstalk, as by using a comb filter, and a luminance signal reproducing circuit reproduces a luminance signal. The reproduced luminance signal is delayed by a horizontal line interval and a difference signal is produced representing a difference between the delayed and undelayed luminance signals. A summing circuit sums the difference signal with the delayed luminance signal to produce a crosstalk-eliminated delayed luminance output signal.
