Filed: 2017-05-18
Abstract: To provide a sheet conveying device and an image forming apparatus capable of achieving a high productivity at a low cost.SOLUTION: A first conveying part 110 conveys a preceding sheet P1 along a conveying guide 210 and pushes down an actuator 200, whereby a tip of the preceding sheet P1 is detected (FIG. 4 (a)). When conveying the tip of the preceding sheet P1 to a second conveying part 120 (FIG. 4 (b)), the preceding sheet P1 is pulled because of a faster conveying speed of the second conveying part 120 than that of the first conveying part 110 and retreated from a rocking range of the actuator 200 (FIG. 4 (c)). This causes the actuator 200 to be returned to a non-detection state and makes it possible to detect a tip of a subsequent sheet. Then, the first conveying part 110 conveys a subsequent sheet P2 and pushes down the actuator 200, whereby a tip of the subsequent sheet P2 is detected (FIG. 4 (d)).SELECTED DRAWING: Figure 4

Title: Combustion system
Inventor: SUZUKI KAYO
IPC: F23N5/24
Filed: 2017-07-14
Abstract: To identify and detect at early stage a failure of a combustion device and a cause therefor.SOLUTION: A time T1, from the point where a driving instruction in an opening direction is sent to a control motor until the point where an opening of a damper is at a predefined large-opening position, is measured. This measurement of the time T1 is repeated to derive the time range of no failure as a normal time range. For example, an average value of the measured time T1 is set as a reference time T1B, and the time range of ±10% based on this reference time T1B is set as a normal time range. When the measured time T1 is within the normal range (T1<T1E) but out of the normal time range (T1L≤T1≤T1H), it is judged that a fuel supply system has a failure. Also, when a driving instruction in a closing direction is sent to the control motor, the normal time range is derived in the same manner to judge whether the fuel supply system has a failure.SELECTED DRAWING: Figure 2
