Title: Intake device for engine
Inventor: OGUSHI TOSHIAKI
IPC: F02M69/00
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of intake flowing velocity due to an injector hole in an intake device for an engine. SOLUTION: An injector hole 10 is formed on an inner wall of an upper portion of an intake port 2, while a fuel injector 9 is attached to a boss 11. A streamlining part 12 having a substantially triangular section which gradually rises toward the downstream side is formed on the inner wall of the upper portion of the intake port 2 on its upstream side of the injector hole 10. Intake flow inside the intake port 2 flows along the streamlining part 12, and smoothly peeled off at its front part 12a. Since spiral flow is not generated inside the injector hole 10, it is possible to prevent intake resistance from increasing and prevent generation of contracted flow.  It is therefore possible to increase flowing velocity of intake and generate intensive tumble flow inside a combustion chamber, for improving combustion efficiency, provide more lean air-fuel ratio and higher EGR, and improve fuel consumption performance.

Title: Heat radiating device of electric component
Inventor: ASAKAWA KYOICHI
IPC: H01L23/36
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent breakage of an electronic component by providing, between a heat sink and a substrate, a spacer for limiting a force acting on the electronic component so that no component is broken with a slight spacing provided to the heat sink. SOLUTION: A first spacer 16 is formed to be height d1 which is slightly shorter tan a distance from a backside of a heat sink 14 to the surface of a circuit substrate 10. This acts so that a distance from the backside of the heat sink 14 to the surface of the circuit substrate 10 does not fail below a specified distance in case of vibration or when the distance becomes shorter as a force is applied to the heat sink 14. A specified distance means such distance as no force acting on solder balls 11b, 11b... cause deformation or crack on them. Since a force acting on an electronic part is limited by the spacer 16, damage to the electronic component is prevented.
