The drain of a power transistor M1 is connected to the non-inverting input terminal of an operational amplifier A and the drain of a transistor M2 is connected to the inverting input terminal of the operational amplifier A to make substantially equal the drain voltages of the power transistor M1 and the transistor M2, of which the gates are connected together and of which the sources are connected together. The drain current of the transistor M2 is outputted via a detection terminal 13 as a current signal proportional to the drain current of the power transistor M1.

Connected to a power element having a first electrode, a second electrode, and a control electrode, a power element protection circuit detects a voltage between the first and second electrodes of the power element and the current flowing through the power element, then logarithmically converts a current proportional to the detected voltage and a current proportional to the detected current individually, then adds the results together, then subtracts a predetermined value from the sum, then antilogarithmically converts the result with an antilogarithmic converter, and then limits the driving of the power element based on the output of the antilogarithmic converter.

The present invention relates to a method of preparing 2,6-dimethylnaphthalene from a feed stream that contains hydrocarbons which contain dimethylnaphthalene isomers. The method includes the following steps:I. distillation and concentration of the dimethylnaphthalene isomers from the feed stream, to form a dimethylnaphthalene fraction,II. isomerization of the dimethylnaphthalene fraction to enrich the dimethylnaphthalene fraction in 2,6-dimethylnaphthalene, to form a 2,6-enriched dimethylnaphthalene fraction,III. purification of 2,6-dimethylnaphthalene from the 2,6-enriched dimethylnaphthalene fraction,wherein step II is conducted in the presence of a catalyst composition containing a synthetic zeolite characterized by an X-ray diffraction pattern including interplanar d-spacing (.ANG.)12.36.+-.10.411.03.+-.0.28.83.+-.10.146.18.+-.0.126.00.+-.0.104.06.+-.0.073.91.+-.0.013.42.+-.0.06,wherein the purification includes crystallization under pressure.
摘要:
In an optical disc player, as signals are read from and written to an optical disc, the optical disc is rotated by a spindle motor and an optical pickup is moved by a sled motor. These motors are both direct-current motors. The motor control circuit of the invention uses a drive circuit based on the BTL method, and additionally uses a resistor that is connected in series with the direct-current motor between the output terminals of the drive circuit. The voltage drop across the resistor is fed back, as positive feedback, to the drive circuit through a feedback amplifier. Since, when the motor is started up, a high current flows through the motor and thus a large voltage drop occurs across the resistor, a high feedback voltage is obtained and thus a high drive voltage is applied to the motor.
