Title: High-frequency field effect transistor
Inventor: MIZUHARA NORIAKI
IPC: H01L21/338
Filed: 2000-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce the parasitic capacitance between the drain and the source of a high-frequency field effect transistor, having mutually meshed comb-like drain and source electrodes. SOLUTION: Compared with drain ohmic electrodes 9 located at active regions, top ends 33c of drain fingers 33a which extend to inactive regions 5 are made to retreat. Compared with source ohmic electrodes 10 located at active regions, the top ends 34c of source fingers 34a extending to inactive regions 5 are retreated similarly. This reduces the opposite faces between the source and the drain in the inactive region, to thereby reduce the parasitic capacitance without ensuring a low on-resistance, relative to gate fingers 8a in the active region.

Title: Image forming device
Inventor: KATO HIRONORI
IPC: G03G21/14
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which does not force a user to perform special operation such as paper removing operation or the like even when temperature rise at the paper non-passing part of a fixing device gets abnormally high and the device is urgently stopped, and where faulty fixing is hardly caused as an image forming device equipped with a fixing device where paper is introduced to a fixing nip part and held and carried so as to heat and fix an unfixed image on the paper. SOLUTION: The temperature of the paper non-passing part of the fixing device is monitored by a sub thermistor (2nd temperature detection means). Even when the sub thermistor detects the abnormally high temperature (equal to or above temperature T2) at the paper non-passing part, the paper carrying is stopped after the ejection of the paper is completed without stopping carrying the paper. At such a time, the target temperature of a heater is lowered. Paper carrying speed is decreased or temperature control is performed based on the temperature detected by the sub thermistor.
