摘要： An electromagnetic clutch includes a rotating member; an electromagnetic coil that is arranged on a rotational axis of the rotating member and generates electro-magnetic force; an output mechanism that has an armature to which return force in a direction away from the electromagnetic coil is applied by a return spring; a cam mechanism that is juxtaposed along the rotational axis to the output mechanism, and has a control cam that is unable to rotate relative to the rotating member, and a cam follower that is able to roll between the control cam and the armature; and a relative rotation restricting device that is arranged on an axis of the cam mechanism, and that is configured to restrict relative rotation between the armature and the control cam when the electromagnetic coil is in a de-energized state.

C. is used for compressive working. When the billet is hollow, it is entirely or locally compressed along the axis of the hollow billet. On the other hand, when the billet is solid, an outer circumferential portion of the billet is compressed. By the compression, the anisotropic structure of the portion where compressed is changed into an anisotropic structure having a direction of easy magnetization in radial directions. The magnet obtained by the method is also disclosed. The magnet has a radially anisotropic structure or novel structures having two different types of anisotropies therein.

摘要： Anisotropic Mn-Al-C alloy magnets exhibiting excellent magnetic characteristics in multipolar magnetization are described. The magnets are obtained by subjecting a polycrystalline Mn-Al-C alloy magnet, which is rendered anisotropic, to compressive working or extrusion at a temperature of from 530.degree. to 830.degree. C. while keeping restrained at least part of the hollow billet along its length so that the at least part is prevented from suffering compressive deformation until fed into a compressive working region. Permanent magnets obtained by the method are also described.

摘要： A channel selection apparatus of the scanning tuning type in which a tuning frequency is swept by a sweeping voltage to select a given tuning frequency. The sweep of the frequency is controlled for each channel by a control signal stored for each channel in the form of a number of pulses to attain exact instant tuning to a specified channel. An operating unit which compensates for temperature drift of the elements comprising the apparatus is provided to correctly compensate for temperature drift of these elements thereby attaining exact tuning.

摘要： A television synchronous receiver is arranged to maintain a 90.degree. phase difference in the broad frequency band of a TV broadcast between a local oscillator signal and another local oscillator signal. This allows a pair of synchronous detectors to detect the in phase components and quadrature components of a received television broadcast signal. A Costas loop is utilized in the generation of the 90.degree. phase difference.
