摘要:
In a fuel injection pump, fuel pressurized by a feed pump is supplied to an accommodation chamber via a communication path having an orifice. An end of the communication chamber on a side of the accommodation chamber is positioned to face an axial end of a minute space between sliding contact portions of a cam and a bush when the cam is at a given angular position. The fuel fed from the feed pump is injected from the end of the communication path axially deep into the minute space between the sliding contact portions so that oil film for lubrication is formed on the sliding contact portions, resulting in suppressing frictional seizure of the sliding contact portions.

A fluorescent display device including a cathode filament increased in mechanical strength and reduced in end cool. A 26% Re-W filament of 0.64 MG corresponding to 0.64 mg in weight per 20 cm in length exhibits an end cool as small as 4.2 mm on each of both sides thereof at a temperature of about 580.degree. C. The end cool in a conventional W filament of the same diameter is increased to about 8 mm. The 26% Re-W filament is increased in mechanical strength by 50% as compared with the conventional W filament.
