Filed: 1988-10-04
Abstract: PURPOSE:To form a superior film quality at a low temperature by a method wherein a plurality of compounds having a specified composition are fed on a substrate and a Ge-containing thin film is formed. CONSTITUTION:Compounds, GeXFYHZ and SiuHvFw, are fed on a heated substrate 4 and are reduced to form a Ge-containing thin film. Here, the thin film has a value of X, Y, u, v>=1, Z, w>=0.

Title: Lubricating device for internal combustion engine
Inventor: YAMAGUCHI MASAFUMI
IPC: F16C3/14
Filed: 1998-09-04
Abstract: PROBLEM TO BE SOLVED: To heighten the hydraulic pressure and improve feeding performance of lubricating oil to a connecting rod bearing part by arranging an oil hole opening part in the outer circumferential face of a journal in the adjacent to a straight line connecting a crank pin center to a crank journal center adjoining to each other. SOLUTION: An oil clearance between the outer circumferential face of a crank journal 16, which is on a straight line C connecting a crank pin center A to a crank journal center B adjoining to each other or in the adjacent to the straight line C in a crankshaft directional view, and a main metal internal circumferential face become the smallest compared with other parts. This is because the crankshaft 15 is so formed that a centrifugal force largely acts on the crank pin 17 side at all times from its weight balance. When the opening part 19a of an oil hole 19 in the crank journal 16 side positioned on the straight line C is positioned in a smallest clearance part at all times except for a piston expansion stroke, the oil is hardly relieved from the upper metal internal circumferential face of the main metal to sides.  The high hydraulic pressure lubricating oil can be thus fed to the connecting rod bearing part.
