Title: Combustion chamber of internal combustion engine
Inventor: HASHIZUME YOSHIMITSU
IPC: F02B23/08
Filed: 1991-01-25
Abstract: PURPOSE:To improve combustion efficiency by causing fuel in a combustion chamber to evaporate quickly and making fuel distribution in the combustion chamber uniform. CONSTITUTION:An irregular surface 7 is formed on the inner circumferential surface of a combustion chamber 5 of an internal combustion engine. This increases the heat transmission area in the combustion chamber 5. As a result, droplets attaching to the irregular surface 7 evaporate quickly.

Title: Manufacture of chip-type multilayer ceramic capacitor
Inventor: YONETAKE NAOTO
IPC: H01G4/248
Filed: 1995-01-20
Abstract: PURPOSE: To prevent the drop of insulation and short trouble caused by the crack occurrence by heat shock by fixing metallic caps onto to the four sides excluding the inner electrode taking-out faces of the outer electrodes on both sides of a chip capacitor. CONSTITUTION: Solder plating is applied by about 6-10μm thicker than the thickness of ordinary electronic components all over the surface excluding the inner bottom of an attached metallic cap 1, and this is fit between both outer electrodes 4 of a chip capacitor. Next, preheating is given enough, and it is annealed after being heated to soldering temperature, and only the four sides excluding the inner electrode taking-out faces of outer electrodes are fixed. In this condition, the stress generated from the difference of thermal expansion coefficient works on the cap 1 via the solder part. And, from the cap 1 to the capacitor, stress works on the periphery of the outer electrode 4, and it becomes force parallel with the connection face between a ceramic 4 and an electrode 4.  Since the bonding force between the electrode 4 and the ceramic 2 is strong to horizontal force, this can prevent the occurrence of cracks.
