摘要： An electromagnetic exciter includes a first suspension having a cylindrical side wall portion coaxial with respect to a cylindrical wall of a yoke of a magnetic circuit assembly, and a spring portion integrally formed at the lower end of the cylindrical side wall portion to support the lower end of the magnetic circuit assembly so that the magnetic circuit assembly is vibratable. An annular support member is secured to the inner peripheral surface of the upper end opening of the cylindrical side wall portion of the first suspension. A printed wiring board that supports a voice coil is supported on the annular support member. A protector has a cylindrical portion installed to cover the outer peripheral surface of the cylindrical side wall portion of the first suspension, and a caulking portion that is bent radially inward over the upper end edge of the cylindrical side wall portion of the first suspension to clamp the printed wiring board between itself and the annular support member.

摘要： Unsaturated dimers which contain 2,4-diphenyl-4-methyl-1-pentene as their main component (i.e., in an amount of greater than 95%) are produced by reacting an .alpha.-methylstyrene at a temperature of from 20.degree. to 100.degree.C. in the presence of a sulfonic acid type cation-exchange resin catalyst and in the further presence of a primary or secondary monohydric alcohol containing from 2 to 5 carbon atoms. By this reaction, side products including a saturated dimer of 1,1,3-trimethyl-3-phenylindane, trimers and higher polymers are produced only in an extremely small amount. The unsaturated dimers are very useful as a molecular weight modifier when employed, instead of dodecylmercaptans, for the production of polymers such as an ABS resin, an AS resin, and the like.
摘要翻译： 含有2,4-二苯基-4-甲基-1-戊烯作为其主要成分的不饱和二聚体（即，大于95％的量）通过α-甲基苯乙烯在20℃至100℃的温度下反应 在磺酸型阳离子交换树脂催化剂的存在下进一步存在，并且在另外存在含有2至5个碳原子的伯或仲一元醇的情况下。 通过该反应，仅产生极少量的包含1,1,3-三甲基-3-苯基二氢茚的饱和二聚体，三聚体和更高级聚合物的副产物。 作为分子量调节剂，当使用不饱和二聚体代替十二烷基硫醇，用于生产聚合物如ABS树脂，AS树脂等时是非常有用的。

摘要： A magnetic direction detecting apparatus has a magnetic sensor head composed of a magnetic core, an exciting coil wound around the core and a pair of detection coils diametrically wound around the core perpendicularly to each other; an oscillator for supplying a rectangular current wave of a single polarity to the exciting coil; and a switching gate openable synchronously with the rectangular wave for permitting only peaks of the same polarity to pass therethrough. The detection of a magnetic direction by using this apparatus does not suffer from restrictions in switching gate-opening timing.

摘要： An electroacoustic transducer includes a magnetic circuit unit having a yoke, a magnet secured to the top of the bottom wall portion of the yoke, and a top plate secured to the top of the magnet. An annular magnetic gap is defined between the peripheral wall portion of the yoke and the top plate. A voice coil is disposed in the magnetic gap of the magnetic circuit unit. A diaphragm is secured to the voice coil, and a space is formed between the diaphragm and the top plate. The outside of the transducer and the space are communicated with each other through mutually communicated through-holes formed in the bottom wall portion of the yoke, the magnet and the top plate, respectively. The through-hole of the yoke has an inner diameter larger than the inner diameter of the through-hole of the magnet. A filter is disposed in the through-hole of the yoke and bonded to the magnet, thereby preventing entry of contamination into the space from the outside of the electroacoustic transducer.
