IPC: F02F3/00
Filed: 1985-09-11
Abstract: PURPOSE:To improve the thermal efficiency of an engine by installing a heat shielding layer around the first ring groove cut in a ring receiving part, thus reducing the width of a top rand part and reducing the dead volume which can not be utilized for combustion. CONSTITUTION:A heat shielding space 23 for shielding the calorific heat supplied to a ring groove 22 is installed into a ring receiving part 21 cut in the first ring groove 22. Then, the calorific heat which inflows into the ring groove 22 from the piston upper surface 12 and a cavity part 11 reduces markedly. Therefore, even if the width of the top and part is reduced to the half of the conventional by setting the ring groove 22 close to the piston upper surface 22, the temperature of the ring groove 22 is kept at 200 deg.C or less where the seizure of the piston ring is not generated, and the sufficient lubricating action is maintained. Therefore, the dead volume which can be not utilized for combustion can be reduced, and the combustion performance is improved, and the thermal efficiency of the engine can be improved.

Filed: 1987-08-13
Abstract: PURPOSE:To eliminate steps of an electrode part without increasing the number process and to prevent disconnection of wirings, by using a BPSG film for forming the sidewall of a gate electrode. CONSTITUTION:A gate oxide film 12 and a gate electrode 13 are formed on one main surface of a silicon substrate 11 by a well known means. Thereafter, a BPSG film 14 is deposited on the gate electrode 13 and the gate oxide film 12. Then, a sidewall 15 of the BPSG film is formed on the side of the gate electrode by anisotropic dry etching. Ions are implanted for forming a source and a drain. Thereafter heat treatment at 800-900 deg.C is performed in order to activate the ion implanted layer and to make the diffusion depths of the source and the drain shallow. The flowing of the sidewall of the BPSG film is performed at the same time in this heat treatment. Thus, the shallow source and drain diffusion layers 16 are formed. Thus, the steep step at the part of the sidewall 15 of the gate electrode 13 is eliminated and flattened without increasing the number of processes. Disconnection of wirings can be also prevented.
