Abstract: PURPOSE:To detect printing without causing malfunction by arranging a detection means detecting a specific pattern recorded by a recording means at the specific position on the recording medium after the recording of an image is completed so as to incline the same with respect to the surface of the recording medium. CONSTITUTION:A reflection type photosensor 14 detecting the density of the footer mark recorded on recording paper at the footer mark position thereof is arranged so as to be inclined at an angle theta with respect to the recording paper 16. Recording is applied to the recording paper 16 in a recording part 11 and a recording paper feed part 12 and, when a recording sensor 13 detects the rear end of the recording paper 16, the recording paper 16 is fed by the recording paper feed part 12 until the footer mark position reaches the recording position of the recording part 11. Next, the recording paper 16 is moved to the position of the reflection type photosensor 14 by the recording paper feed part 12. Since the reflection type photosensor 14 is arranged at the angle thetaof inclination so as to reduce the influence of external light on output, it can be automatically judged whether the recording of image data is normally performed without causing malfunction.

IPC: F02D43/00
Filed: 1990-02-15
Abstract: PURPOSE:To set ignition timing optimum in an advance timing side so as to always generate maximum torque by using an advance timing value, map- calculated from an engine speed and a throttle opening, to control ignition. CONSTITUTION:In this ignition system, air-fuel ratio of a mixture supplied to an internal combustion engine is controlled in a region leaner than theoretical air-fuel ratio by using a correction coefficient KAFTA map-calculated from a relation between an engine speed NE and a throttle opening TA. In this ignition system, ignition control is performed by using an advance timing value calculated from a relation between the engine speed NE and the throttle opening TA. Since the advance timing value of ignition timing is map-calculated with the throttle opening TA serving as a parameter in such a way as mentioned, maximum torque can be realized even in an accelerator high opening control region, where the air-fuel ratio is decreased in accordance with increase of the throttle opening TA, that is, in a relation where throttle opening TA > fixed value x deg..

IPC: G01R29/26
Filed: 1982-03-08
Abstract: PURPOSE:To simplify a device required for the calculation of an effective value of a forecasting error to set up the threshold value of noise detection, by calculating said effective value from an auto-correlation function and a forecasting factor found in a process to calculate a forecasting value. CONSTITUTION:An auto-correlation function rj of an input signal xi from an auto-correlation function calculating circuit 10 is sent to a forecasting calculation circuit 11 and a forecasting factor aj and the effective value DELTAxrms of a forecasting error are calculated. A forecasting value operating circuit 30 consisting of P units of registers 31-1-31-P, P units of adders 32-1-32-P and an adder 33 calculates forecasting values x'i=a1xi-1+...+apxi-p. A forecasting error detecting circuit 40 finds out a forecasting error DELTAxi. The error DELTAxi is delayed to DELTAxh by a delay circuit 80. A comparator 70 compares  DELTAxh  with the output Ls  of a threshold setting circuit 50 and discriminates a noise at  DELTAxh >=Ls. The threshold value setting circuit 50 multiplies xrms by a secsitivity factor S set  up by a sensitivity setter 51 and outputs Ls. When noise is detected in the  error xh, a signal compensating circuit 23 replasces the error xh with x'h to  remove the noise.
