    摘要： A discharging circuit for a power source device with a rectifier circuit used in an power source for driving a motor in which when the alternating current power source is turned off and the load is electrically separated, the voltage of a time constant selection circuit (22, 23) falls rapidly, the voltage across a diode (25) rises, a Schmitt circuit (24) is activated, the circuit consisted of a transistor (27) and a resistor (26) is conducted, and a smoothing capacitor (28) is discharged, and hence the heat generation at the resistor is decreased and the concern over unsafety due to delayed discharge of the capacitor is eliminated.

The toothed belt 10 comprises a belt body 13 including a tooth rubber portion 11 and a backing rubber portion 12. A surface of the tooth rubber portion 11 is covered with a facing fabric 20. The facing fabric 20 is subjected to RFL treatment, and has an outer surface 21 covered with a hardened material of a first epoxy resin. The softening point of the hardened material of the first epoxy resin is, for example, 110° C. or higher. The epoxy equivalent of the first epoxy resin is, for example, 100 to 1500 g/eq. Alternatively, the facing fabric 20 is subjected to impregnation treatment with a treatment agent including a second epoxy resin, a hardener for hardening the second epoxy resin, and a rubber component.

    摘要： It has been required to economically produce a large amount of optically active γ-lactone derivatives (for example, pantolactone), which are useful as intermediates in synthesizing useful substances such as pharmaceutical drugs. To achieve this object, it is advantageous to employ an enzymatic technique of asymmetric hydrolysis with a hydrolyzing enzyme lactonase. However, it remains troublesome to prepare the enzyme or utilize a microorganism capable of producing the enzyme. Also, it is difficult to obtain a sufficient and stable enzymatic activity in the case of using recombination techniques. In producing lactonase, which asymmetrically hydrolyzes a γ-lactone derivative such as racemic pantolactone selectively, by a recombination technique, both mature lactonase DNA and signal peptide region DNA are transferred into a host. Thus, a stable lactonase activity comparable to naturally-occurring one can be achieved and a transformant sustaining a high enzyme activity in a stable manner can be acquired, thereby allowing the efficient and industrially advantageous asymmetric synthesis of γ-lactone derivatives.

    摘要翻译： 需要经济地生产大量的用作合成有用物质如药物的中间体的光学活性γ-内酯衍生物（例如泛酸内酯）。 为了达到这个目的，使用水解酶内酯酶的不对称水解酶技术是有利的。 然而，制备酶或利用能够产生酶的微生物仍然是麻烦的。 此外，在使用重组技术的情况下，难以获得足够稳定的酶活性。 在制备内含子选择性地水解γ-内酯衍生物如外消旋泛酸内酯的内切酶中，通过重组技术，将成熟内含酶DNA和信号肽区DNA两者转移到宿主中。 因此，可以获得与天然存在的活性相当的稳定的内含酶活性，并且可以获得以稳定的方式维持高酶活性的转化体，从而允许有效和工业上有利的γ-内酯衍生物的不对称合成。

    摘要： Windings of each phase in a three-phase AC motor are independent of one another. A motor control unit gives, to windings of each phase (U, V and W-phase), currents (IU, IV, IW) obtained by adding, to a fundamental sine wave current, a current having a frequency which is three times as high as that of the fundamental sine wave current. That is, IU=I·sin ωt+Ia·sin 3ωt: IV=I·sin (ωt+⅔π)+Ia·sin 3ωt: IW=I·sin (ωt+{fraction (4/3)}π)+Ia·sin 3ωt Also, amplitude Ia of a current having a frequency which is three times as high as that of the fundamental sine wave current is set to a predetermined value smaller than amplitude I of the fundamental sine wave current.
