摘要： PROBLEM TO BE SOLVED: To provide a motor control device which suppresses a decrease in the maximum output power of a motor that is caused by the fluctuation of power voltage in a motor driving circuit or the effect of individual irregularities of motor performance. SOLUTION: The motor control device includes a power control unit 100 which sets a larger upper limit leading angle θa_lmt, which is the upper limit of a current leading angle, as an output voltage Vpin from a battery 60 lowers, and an upper limit output setting unit 40 which sets a smaller upper limit output power of the motor 70 as the output voltage Vpin from the battery 60 lowers and sets an upper limit torque Tr_lmt corresponding to the upper limit output power and the rotation speed MOT_rpm of the motor 70, and a controller 1 which generates control signals UH, UL, VH, VL, WH, and WL to a PDU 50 so that the current leading angle does not exceed the upper limit leading angle θa_lmt and an output torque of the motor 70 does not exceed the upper limit torque Tr_lmt.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive degassing plug for die casting; and a die casting method using the degassing plug so as to make the casting costs low. SOLUTION: The degassing plug 4 is formed by the compression molding of cutting chips from cutting work in a state of keeping gas permeability. The degassing plug 4 is interposed in a degassing passage 3 through which the gas in the cavity 2 of a die-casting mold 1 is discharged. Then molten metal (a) is poured into the cavity 2, with the degassing plug 4 interposed in the degassing passage 3. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a releasing agent reducing an oxide film which is formed on the surface of molten metal in casting.
SOLUTION: A reducing agent (calcium hydride: CaH
2 ) in a releasing agent 6 is decomposed into Ca and H
2 by the remaining heat of a mold and the heat of the molten metal. These Ca and H
2 are combined with oxygen in the cavity to become CaO and H
2 O respectively. Thus, oxygen in the cavity is consumed so that MgO and Al
2 O
3 are hard to be formed. Even if some amount of oxygen left in the cavity is reacted with Mg or Al existing in the molten metal to become an oxide film of MgO or Al
2 O
3 , these MgO and Al
2 O
3 are reduced, as shown in the following formulas, so that the film is eliminated and fluidity is secured. Namely, the formulas are MgO + Ca → Mg + CaO and Al
2 O
3 + 3Ca → 2Al + 3CaO.

摘要翻译：解决方案：提供一种还原在铸造中形成在熔融金属表面上的氧化膜的脱模剂。解决方案：脱模剂6中的还原剂（氢化钙：CaH 2 ）通过模具的剩余热分解为Ca和H 2 ，并且熔融金属的热量。这些Ca和H 2 与空腔中的氧气分别成为CaO和H 2 O。因此，空腔中的氧被消耗，使得难以形成MgO和Al 2 SB 3 O 3。即使留在空腔中的一定量的氧气与存在于熔融金属中的Mg或Al反应，成为MgO或Al O 3 的氧化膜，这些MgO 并且如下式所示，还原Al 2 O 3 SB 3，从而消除膜并确保流动性。即，式为MgO + Ca→Mg + CaO和Al 3 SB 3 + 3Ca→2Al + 3CaO。版权所有（C）2004，JPO

摘要： PROBLEM TO BE SOLVED: To greatly suppress generation of a casting defect due to gas by suppressing rapid increase of a pressure in a cavity when shifting to a positive pressure in the vacuum die casting device so as to maintain a gas quantity in a cavity to a minimum. SOLUTION: The vacuum die casting device 1 is arranged with a die 2 having a cavity 5 for casting forming, a suction passage 7 communicating to a cavity 2 and a vacuum mechanism 6 to keep the inside of the cavity 5 to a evacuated state below the atmospheric pressure, in addition, a relief valve 27 in the suction passage 7. The relief valve 26 is opened when the cavity 5 under evacuated pressure is shifted to a positive pressure resulting from high speed injection of a molten metal.
