Title: Image forming device
Inventor: NANBA KUNIHARU
IPC: G03G15/20
Filed: 2001-01-22
Abstract: PROBLEM TO BE SOLVED: To detect easily the abnormality of a cutoff relay of a fixing heater circuit in an image forming device of an electro-photographic method. SOLUTION: This device is constituted such that frequency detection cannot be performed in a state wherein a cutoff relay 4 is cut off by providing the frequency detecting circuit 6 of an AC power source 5 at a stage succeeding cutoff relay 4. By this constitution, when contacts of the relay 4 are normal (non-welded) at the time the contacts of the relay 4 are turned OFF, a zero cross signal is not outputted from the frequency detecting circuit 6. But at the time the contacts of the relay 4 are turned ON by a control signal from a control part 8, the zero cross signal is outputted from the circuit 6 for the first time. Moreover, when the contacts of the relay 4 are abnormal (welded), the zero cross signal is outputted even when the control part 8 does not turn the relay 4 ON, and thus the control part 8 can detect the abnormality of the relay 4 at that time.

Title: Tire air pressure detector
Inventor: TOMINAGA MOTONORI
IPC: B60C23/06
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To improve the detection accuracy of tire air pressure by accurately correcting an influence of a tread lift. SOLUTION: Tread lift correction is not executed until a differential pressure decision value ΔD'AVE exceeds a given threshold value Cth, and is executed upon such an excess. Specifically, the differential pressure decision value is corrected only if a tread lift has a truly great influence and correction is necessary, which can prevent dispersion in the differential pressure decision value caused by correction despite a minor tread lift influence. The differential pressure decision value is, however, corrected accurately under a great tread lift influence, so that an accurate differential pressure decision value can be computed and that degradation in detection accuracy of tire air pressure can be prevented.
