Title: Knocking control device for internal combustion engine
Inventor: NAKAI KAZUHIRO
IPC: F02D43/00
Filed: 1994-11-08
Abstract: PURPOSE: To simplify the computing processing of fuel increase quantity at the time of lag, and while to improve the fuel consumption at the same time. CONSTITUTION: Lag quantity per each air cylinder AKNK1 of all air cylinders are summed up so as to obtain the total lag quantity AKALL (step 41). This total lag quantity AKALL is compared with the lag increase quantity execution judgment value FRET (step 142), and in the case where AKALL>KFRET, Fknk is computed on the basis of a map of the engine speed Ne and the lag increase quantity Fknk (step 143). In the map to be used at this stage, lag increase quantity Fknk is set at 0 in the low engine speed side (for example, at 2000rpm or less), because the low engine speed side has a room of exhaust temperature in relation to the high engine speed side and the increase of lag is therefore unnecessary, and furthermore, it improves the emission. On the other hand, in the case of AKALL<=KFRET, the lag increase quantity Fknk is set at 0.

Abstract: PURPOSE:To add a low-cost waveform digitizing function to an oscilloscope by a photodetecting element provided in the center of a flank part of a CRT, D/A converters for vertical axis and horizontal axis position variation, and a microcomputer which controls them. CONSTITUTION:A bright line extends to the flank of the CRT 5 and the photodetecting element 4 is fitted at its center part. The D/A converters 13 and 14 for vertical axis and horizontal axis position variation receive vertical axis and horizontal axis position variation data 15 and 16 from a microcomputer 18 and move the position of a waveform on the tube surface up and down, and right and left. When the microcomputer 18 recevies a start instruction for digitization, the data 15 and 16 are set to 0 to make an upward shift in waveform position. The data 15 of the converter 13 is counted up to move the waveform upward and the data 15 when the element 4 is aligned with the bright line position on the flank of the CRT 5 is stored. Then, the data 16 is counted down to obtain position information on the bright line position as well, and bright line position information on the vertical axia based upon the data 16 as an address is stored, thus digitizing the waveform information on the tube surface.

Title: Image processor
Inventor: NISHITANI TAKUJI
IPC: G06T7/00
Filed: 1986-11-19
Abstract: PURPOSE:To divide an area of an image at a high speed by deriving the maximum brightness and the minimum brightness from a picture element in a small area centering around the picture element, and repeating plural times a processing for replacing a value of the picture element being near the brightness of each picture element with the brightness of each picture element, with respect to all the picture element in the image. CONSTITUTION:Brightness of each picture element for constituting an image, and brightness of the picture element being in the vicinity of the picture element are compared, and in case they are the brightest and the darkest, they are left as they are, and in other case, an arithmetic operation for replacing them with a value of the near brightness is repeated with respect to all the picture elements, and thereafter, brightness of each picture element and brightness of an adjacent picture element are compared, and if there is a difference exceeding some suitable value, it is decided that a boundary of the area exists between the picture elements. The brightness of the brightest picture element and the darkest picture element is not varied in a local range, therefore, it becomes the center of the area. Other picture element becomes the same brightness as that of the picture element having near brightness in the vicinity, therefore, the area is enlarged gradually. When the arithmetic processing is repeated by a suitable number of times, the picture elements in one area all come to have the same brightness, therefore, the boundary of the area can be determined easily.
