Title: Variable compression-ratio mechanism in internal- combustion engine
Inventor: NARUOKA TAKAO
IPC: F02D15/02
Filed: 1981-10-20
Abstract: PURPOSE:To make it possible to simplify a variable compression-ratio mechanism, by  providing a selector valve for switching the supply of oil between a main passage of  low compression-ratio and a main passage of high compression-ratio, in an oil supply  circuit. CONSTITUTION:An eccentric bearing 25 rotates under the inertia force of a piston 12  during cranking, and comes, to a stop when a rock pin 26 enters into a hole 26 upon  the piston being in the vicinity of its top dead center so that the high compression-ratio  is brought about. Then, the lock pin 26 is extracted when oil is stopped to flow into  an oil chamber 45 for fixing the lock pin 26 upon the piston 12 being in the vicinity of  its bottom dead center, so that the low compression-ratio is brought about, however,  upon starting, the high compression ratio is maintained since oil is filled in the oil chamber 45. Next, when negative intake pressure exceeds a predetermined value after  starting, a selector valve 36 operates by the actuation of a negative pressure switch 52  so that oil is fed to a main passage 37 of low compression ratio for supplying oil to the oil chamber 45 upon the pistron being in the vicinity of its top dead center, however,  the lock pin is extracted upon the piston beingin the vicinity of the bottom dead center  since oil is not supplied, thereby the low compression-ratio is maintained with the  intake stroke being long.

Title: Lamellar spring for vehicle
Inventor: SHIMOJIMA SHIGEAKI
IPC: F16F1/18
Filed: 1980-11-28
Abstract: PURPOSE:To avoid the ineffective use of material, by making openings in the part of each trunnion-type leaf spring, which is tightened by U-bolts through a pad, and by piling up the leaf springs. CONSTITUTION:Openings are provided in leaf springs L to make hollow the part 1c of a lameller spring 1, which is tightened by U-bolts 3 through a pad 4. Since peripheral portions 1d are left in the leaf springs L, they can enough resist the compressive force of the U-bolts 3. Because the part 1c remains completely pushed by the pad 4, the part does not function as leaf spring. For that reason, no adverse effect is produced by the presence of the openings. As for the trunnion-type lameller spring 1, the weight can be greatly reduced by providing the openings because the pad 4 is much longer than that of other-type lamellar springs.
