IPC: H02P29/00
Filed: 2015-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a motor control device that is able to appropriately estimate the temperature of an evaluation part at the time of restart after stop, without being affected by a change in an ambient temperature.SOLUTION: The temperatures of two parts selected from a heat sink, control circuit IC, drive circuit IC, switching element and electric motor are detected. During stop of an electric current control part, a temperature estimation part stores the estimated temperature (Txo), first detection temperature (Ts1o) and second detection temperature (Ts2o) of an evaluation part. During restart of an electric current control part, the ratio of a temperature difference (ΔTso) between the first detection temperature and the second detection temperature during stop to a temperature difference (ΔTs) between the first detection temperature and the second detection temperature during restart is calculated as an estimation gain. Then, the temperature of the evaluation part during restart is estimated on the basis of a temperature difference (ΔTx) obtained by multiplying a temperature difference (ΔTxo) between the first detection temperature and the estimated temperature of the evaluation part during stop, by the estimation gain, and on the basis of an increased temperature (ΔTi) calculated from the integrated value of electric currents.SELECTED DRAWING: Figure 7

Filed: 2015-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a heat treatment apparatus capable of preventing the degradation of an O ring due to irradiation with flash light, and a method for manufacturing the heat treatment apparatus.SOLUTION: A sealing structure is achieved by sandwiching an O ring 21 between an upper chamber window 63 and a chamber side portion 61 and pressing a clamping ring 67 against a top of a peripheral portion of the upper chamber window 63. Grooving is performed on a lower surface and an upper surface of the peripheral portion of the upper chamber window 63, to thereby form a plurality of grooves 22 thereon. Flash light traveling into the peripheral portion of the upper chamber window 63 during irradiation with flash light is reflected by the plurality of grooves 22 and is prevented from traveling toward the O ring 21. This significantly reduces an amount of flash light reaching the O ring 21, and thus degradation of the O ring 21 due to irradiation with flash light can be prevented.SELECTED DRAWING: Figure 8
