摘要:
A system for detecting and controlling an engine knocking the determination of occurrence of knocking is based on a present data on the detected pressure vibration energy in a combustion chamber of the engine and a value associated with a previous data on the detected pressure vibration energy in the combustion chamber so that an accurate detection of engine knocking can always be achieved. Furthermore, the knocking can be discriminated from the background noise even when the engine revolution speed is high.

摘要:
A method of treating raw materials containing components of metals of the group IVb of the Periodic Table, which comprises heat-treating a raw material of a component of a metal of the group IVb of the Periodic Table containing coloring poisonous metal components such as Mn, V and Cr components in the presence of a flux composed mainly of an alkali metal nitrate or an alkali metal peroxide which is a thermal decomposition product of the alkali metal nitrate in an amount 2 to 5 times the amount of the raw material on the weight basis in a non-reducing atmosphere to thereby effect fluxing reaction, and subjecting the resulting fluxing reaction product to a leaching treatment of at least one stage in an aqueous medium to separate the fluxing reaction product into said coloring metal components and a concentrate of the component of the group IVb of the Periodic Table which is acid-soluble and substantially free of said coloring poisonous metal components. In practising this treating method, if a residue left after the above leaching step is incorporated into a mixture of the raw material and the flux, the composition is granulated and the granulated composition is heat-treated, the fluxing reaction of the raw material can be accomplished while keeping the granulated composition in the substantially non-sticky granular state throughout the fluxing heat treatment.
摘要:
A component mounting apparatus includes a component feeder that feeds a component with its bump electrodes facing down, a mounting head that mounts the component onto a substrate, a supporting base that secures the substrate, and a positioning device that aligns the component with the substrate. The mounting head includes an ultrasonic vibration generator, an ultrasonic vibration propagation member that conveys the ultrasonic vibration provided by the ultrasonic vibration generator to a working face holding the component as vibration parallel thereto, a pressure loader that applies a pressure load to the working face from a position immediately thereabove in the direction perpendicular thereto, and a heater that heats the vicinity of the working face. Thereby, ultrasonic bonding is carried out with high reliability even if the component has a number of bump electrodes on its face.

摘要:
Provided is a light source that has high reliability and hardly causes conductivity failure between a light emitting device and a conductive land. In an LED light source of the present invention, an LED bare chip is mounted to conductive lands of a substrate, using bumps (55a, 55b). The LED bare chip (D65) is provided with a p-electrode (Lp) and an n-electrode (Ln) on a rear surface. The p-electrode (Lp) is larger in area than the n-electrode (Ln). The p-electrode (Lp) is bonded to a corresponding conductive land via four bumps (55a), whereas the n-electrode (Ln) is bonded to a corresponding conductive land via one bump (55b). A bonded area (Sn) between the n-electrode (Ln) and the bump (55b) is larger than a bonded area (Sp) between the p-electrode (Lp) and one of the bumps (55a).
