Title: Combustion chamber of direct injection type diesel engine
Inventor: SHIOZAKI CHUICHI
IPC: F02B3/06
Filed: 1992-01-31
Abstract: PURPOSE:To reduce exhaustion of unburned fuel as a white fume in exhaust gas by providing diameters of an entrance part and an inner circumferential wall of a combustion chamber relatively longer and removing the upper part of a conical bulged part in the center part of the bottom. CONSTITUTION:The diameter of an entrance part 4 is provided relatively longer for the shape of a combustion chamber 3 opened to a top surface 2 of a piston of a direct injection type diesel engine. The fuel mist 9 blown out of a nozzle 8 of an injection nozzle 7 is thus prevented from being flown to the outside of the combustion chamber 3. The diameter of the inner circumferential wall 5 is provided relatively longer. The amount of the fuel mist 9 colliding with a direct inner circumferential wall 5 is reduced. An upper part 6 of a conical bulged part in the center of the bottom part is removed. The speed of air current at the removed part is delayed thereby and diffusion of the fuel is prevented, to activate the combustion. Exhaustion of unburned fuel as fume in the exhaust gas is thus reduced.

Title: Hybrid type magnetic bubble memory element
Inventor: MIYASHITA TSUTOMU
IPC: G11C11/14
Filed: 1986-02-28
Abstract: PURPOSE:To improve transfer margin at a junction part by shortening a plasma processing time applied in the direction from an ion injection area toward the ion injection bundary, at the junction part of an ion injection transfer path and a 'permalloy(R)' transfer path. CONSTITUTION:The rare gas plasma processing which is executed to increase the inductive anisotropic magnetic field change of an ion injection layer 21, is made gradually less applied as it goes from the layer 21 to the ion injection boundary 23. Consequently, a resist pattern 24 that is tapered in the direction from the boundary 23 to the layer 21, is formed. As a result, the amount of plasma reaching the layer 21 increases as the plasma gradually etches the tapered part. Therefore, the drastic change of the inductive anisotropic magnetic field change of lattice distortion in the vicinity of the boundary 23 is metigated. In such a way, the transfer margin at the junction part of the path 21 and that 22 can be improved with a simple constitution of the element.
