Title: Electric wave reflection reducing structure for aircraft
Inventor: YANAGIYA MASASHI
IPC: B64C1/00
Filed: 1990-11-26
Abstract: PURPOSE:To reduce scattering of electric waves largely, and let them less likely to be caught by a radar or the like by changing the conductivity along the axis close to the surface at rear edge part and/or groove front part of an aircraft to set the conductivity lower as it is closer to the rear end edge of the rear edge part and/or groove front part. CONSTITUTION:A main blade 5 has a rear edge part 2, a groove 4, and a groove front part 3, and the conductivity close to the surface is set smaller as it gets farther to the rear end edge along the axis of an aircraft. The groove front part is therefore formed of carbon fiber plastic or the like to set the conductivity smaller as it goes from (a) to (b). The conductivity is similarly reduced from (c) to (b) at the rear edge part 2. The conductivity may be changed by surface painting, or it may be performed by attaching a thin material to the surface. A surface current 6 sent to the aircraft by incidental electric waves from the front can thus be damped continuously as it goes toward the rear end, and by reducing scattering 7 of electromagnetic waves generated at each rear end, they become less likely to be caught by a radar or the like.

Title: Exhaust emission control device for diesel engine
Inventor: NIIZAWA MOTOHIRO
IPC: F01N3/08
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To inhibit the variable concentration of HC in the exhaust in a device wherein the after-injection is performed in the expansion or exhaust stroke after the main injection of the fuel, and the unburned HC is supplied to a NOx catalyst as a reducing agent, by determining an injection pattern so that the HC supplied to the NOx catalyst is equalized to flow. SOLUTION: In the control of the after-injection by an electronic control unit 41, an inlet temperature of a NOx catalyst is compared with a prescribed value which is the lowest value (about 250 deg.C) of a temperature for the reduction of NOx. As a result of the comparison, when the inlet temperature is higher than the prescribed value, the after-injection is performed under a condition that the temperature of the cooling water is over the prescribed value. For this after-injection, an after-injection amount ratio is retrieved by using a map corresponding to the engine speed and load.  Then the after-injection amount per one cylinder is calculated on the basis of the after-injection amount ratio and the main injection amount, the obtained value is corrected on the basis of the water temperature, then the after-injection pattern is determined on the basis of the after-injection amount, and a fuel injection valve 17 is controlled to perform the after-injection corresponding to the pattern.
