Title: Misfire judger for internal combustion engine
Inventor: NAKABAYASHI KATSUHIKO
IPC: F02P5/15
Filed: 1990-02-27
Abstract: PURPOSE:To obviate a misjudgment by detecting a single misfire at one expansion process from a deviation in crankshaft speed, comparing the frequency of this single misfire with a threshold value interlocking with variations in water temperature and engine load, and discriminated a misfire state. CONSTITUTION:In this device, there are provided with a single misfire frequency calculating means, calculating the frequency of a single misfire, and a threshold value setting means setting a threshold value according to variations in water temperature and engine load. Then, the frequency of the single misfire is com pared with the threshold value, thereby discriminating the occurrence of a misfire state with a misfire state discriminating means. With this constitution, a variation in an amount of hydrocarbon occurrence at time of misfire state judging is checked, and such a situation that an amount of hydrocarbon genera tion is suddenly increased, whereas it is not yet judged as the misfire state is prevented from occurring.

Title: Wafer-dicing device
Inventor: MIMATA TSUTOMU
IPC: H01L21/301
Filed: 1985-03-11
Abstract: PURPOSE:To facilitate the release of wafers after dicing by a method wherein the liquid on the upper surface of a wafer is removed by spraying a gas to the upper surface before isolation of the wafer from an attraction table after dicing. CONSTITUTION:Since the wafer 1 is diced in the state of being cooled with a liquid such as water, it is very difficult to remove the wafer 1 adhered to a dicing table (attraction table) 21 with water, etc. from this table 21. Therefore, the liquid in the periphery of the wafer 1 should be eliminated by partly spraying air 25 through a tube 24 to the wafer 1 from obliquely above it. This manner can facilitate later processes such as release and enables the prevention of mechanicl damage to the wafer 1.
