Title: Misfire detecting device for internal combustion engine
Inventor: IZUMI AKIRA
IPC: F02P17/12
Filed: 1993-07-16
Abstract: PURPOSE:To perform constantly stable detection of the misfire of an internal combustion engine in spite of production of the change of an operation state and the generation of noise by means of an integrated value of a value related to a combustion chamber internal pressure measured in synchronism with a crank angle on and after the given crank angle of the internal combustion engine and the running state of the internal combustion engine. CONSTITUTION:In an internal combustion engine A, the crank angle of a crank shaft, a pressure in a combustion chamber, the number of revolutions, and a load are detected by means of detecting means, B, C, E, and D, respectively, for an exclusive use. In which case, based on a detected load and the detected number of revolutions, the running operation of the internal combustion engine A is detected by a detecting means F. A value related to a detected pressure in a combustion chamber is integrated in synchronism with a crank angle in a detected given crank angle range, and the misfire of the internal combustion engine A is detected by a detecting means G according to the integrated value and the running state of the internal combustion engine A. Even in a case of a fluctuation in a pressure owing to the change of a combustion state and even when noise is overlapped with a pressure signal, this constitution enables constantly stable detection of a misfire.

Title: Image forming device and image forming method
Inventor: TSUKADA MASAHARU
IPC: B41J29/46
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device and an image forming method capable of removing a problem caused by the generation of electrical noises in particular among the problems caused when a regenerative cartridge such as a refill cartridge is used. SOLUTION: When there are contact defects at high-voltage feed sections in the highvoltage sequence during a printing action, noises are generated. The number of noises is counted by a noise counter 2. The count value Kn of the noise counter 2 is read out, and whether the count value Kn is larger than the prescribed number (k) or not is judged. If the count value Kn of noises is larger than the prescribed number (k), it is judged that the highvoltage contact point of a cartridge has an abnormality, the subsequent printing action is prohibited, and the abnormality of the cartridge is reported to a controller. Since the noises of the high-voltage contact point section may be generated very rarely, the prescribed number (k) is set in consideration of this number.

Filed: 1988-08-10
Abstract: PURPOSE: To obtain an alteration certifying structure by adopting the constitution in which the color development of a desired region is faded to the infeasibility of restoration and re-color development is impossible by peeling two sheets of adjacent layers at contact surfaces. CONSTITUTION: This alteration certifying structure is formed of a substrate 41 consisting of alumina foil, a Ta sputtered layer 40, a translucent Ta2 O5 thin film 42 formed on an anode and a strip 44 for overlay of transparent plastic. One end of the strip 44 is easily peeled by picking up the tab of an underlying non-adhesive strip 45 with the fingertips. When the strip 44 is pulled, the thin film 42 peels from a color developing metallic layer 40. The thin film 42 is colorless and the layer 40 is metallic gray in the part (b). The darkly generated color is admitted through the strip 44 in the tight contact part (a). The colors of the layer 40 and the film 42 are invariably annihilated when both are once peeled and the intrinsic colors are not reproduced even if both are pressed again. Then, the alternation is surely certified.
