Patent JP-H0533708-A (JP)
Title: Fuel injection device for engine
Inventor: MAMIYA KIYOTAKA
IPC: F02D41/02
Filed: 1991-07-31
Abstract: PURPOSE:To prevent the deposition of fuel onto the wall surface of the suction port and the occurrence of smoking at the ignition plug, by changing over the fuel injection timing in such a manner that, when the alcohol concentration in the fuel is high, the fuel may be injected in the suction stroke, and that, when the alcohol concentration is low, the fuel may be injected outside the suction stroke. CONSTITUTION:In cases where alcohol, or a mixed fuel having a high alcohol concentration, is used as the fuel, the fuel injection timing is set in the suction stroke at the time when the alcohol concentration is a high alcohol concentration exceeding a specified concentration. The injection timing is set in the exhaust stroke at the time of a low alcohol concentration. At the time of a high alcohol concentration, the injected fuel impinges upon a suction valve 5 to return therefrom, thus concentrating at a zone near an ignition plug 7 to cause layer- formation. At this time, since the injected fuel is directly led to a combustion chamber 2 together with the flow of the air sucked thereinto, deposition of the fuel onto a suction port wall surface and the like does not occur. Further, since the injection center line is directed toward the center of the combustion chamber 2, nor is deposition onto the combustion chamber wall surface likely to occur. Since, on the other hand, the fuel is injected in the exhaust stroke at the time of low alcohol concentration, the fuel is fully gasified within the suction port 3 by the time when the suction valve 5 is opened.

Title: X-ray fluoroscopic apparatus
Inventor: KADOWAKI TOSHIO
IPC: A61B6/00
Filed: 1988-07-30
Abstract: PURPOSE:To automatically rationalize the contrast of an output image by eliminating the load of manual operation by the automatic detection of a halation region and the automatic positioning of a compensation filter on the basis of said detection. CONSTITUTION:The video signal obtained from a TV camera apparatus 5 is digitalized by an A/D converter 6 to a divide a picture into matrice and image intensity is shown as an integer value at every divided small part (pixel). This image data is binarized on the basis of a threshold value distinguishing between an over-intensity part and other part in an image processing apparatus 7 and the angle or area of the over-intensity part where the level of the video signal brings about halation. On the basis of the processing result of the image processing apparatus 7, a compensation filter control apparatus 10 controls the drive mechanism mounted in a collimator apparatus 2 to perform the positioning of a filter plate 22. As a result, since only the excessive part of image intensity is covered with a compensation filter, halation is avoided and an image holding a contrast properly can be obtained.
