Title: Ignition timing controller of internal combustion engine
Inventor: ARAKI AKIHIKO
IPC: F02P5/15
Filed: 1988-06-16
Abstract: PURPOSE:To avoid aggrevation of the drivability due to variation in ignition timing at the normal temperature and prevent knocking by variably setting the valve of limitter which limits variation in ignition timing. CONSTITUTION:A means A sets an ignition timing according to the operation state of an engine. And a means B detects the engine temperature. Additionally, a means C sets the value of a limitter which limits variation in ignition timing for every ignition within the specified range according to the engine temperature. When the difference between the newly set ignition timing and the precedent ignition timing exceeds the limitter value, a means D resets the newly set ignition timing to the variation from the precedent ignition timing as a limitter value. Meanwhile, a means E sends an ignition signal to an ignition device F at the specified ignition timing. As a result, the aggrevation of the drivability due to variation in ignition timing at normal temperature may be avoided and the knocking be prevented from occurring when the temperature of the engine is high.

Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To enable the speedy, steady supply of a highly precise image by attaching a liquid developer to a plate surface, emitting light to the plate surface after printing, and making a hydrophobic substance remaining on the plate surface hydrophilic. SOLUTION: Based on given control information, a liquid emission part 3 drops a hydrophobic substance containing a capsuled light-changeable substance onto a rotary drum 4 set opposite it, thereby forming a recess-and- projection plate. A liquid-developer attachment part 5 attaches liquid-developer ink or the like to the surface of the plate formed on the rotary drum 4. A transfer-body carrying part 6 carries a transfer body 7. The rotary drum 4 prints by transferring an image to the carried transfer body 7 from the surface of the plate with the liquid developer attached to it. After the printing, a light emission part 8 emits light having light-changeable wavelength, which is inherent in the substance, to the plate on the rotary drum 4, thereby making the residual hydrophobic substance hydrophilic.  Further, a water-containing body 9 wipes off the substance when its sticking force to the plate has become weak.
