    • It is an object of the present invention to provide a non-conjugated cyclic diene and a non-conjugated cyclic diene composition which enable the production of a polymer based on non-conjugated cyclic diene which makes it possible to produce a (co)polymer at a high degree of polymerization activity, and a method of producing a polymer based on non-conjugated cyclic diene which makes it possible to produce a (co)polymer at a high degree of polymerization activity. A non-conjugated cyclic diene is used which meets at least one of the following requirements: (1) it contains a compound having a seven-membered cyclic triene hydrocarbon structure in a specific amount or less and (2) it contains a conjugated polyene compound having an eight-membered bicyclic hydrocarbon structure in a specific amount. Also, in a method of producing a non-conjugated cyclic diene polymer, the aforementioned non-conjugated cyclic diene is supplied to the polymerization or copolymerization using an olefin polymerization catalyst containing an organic aluminum oxy compound and/or an ionizing ionic compound. Also, in another method of producing a non-conjugated cyclic diene polymer, a non-conjugated cyclic diene which is obtained by bringing a crude non-conjugated cyclic diene into contact with an alkali and then removing at least a part of a low-boiling point fraction and at least a part of a high-boiling point fraction is used for the polymerization.

    • A cable clamp of the present invention comprises a base having a fixing portion on the lower surface, a flat clamp rockingly connected to the base, and a means for locking a distal end of the flat clamp to the base engageably or disengageably. The cable clamp retains electric wires between the base and the flat clamp. The locking member comprises a plate-shaped protrusion provided on the flat clamp or the base and a retaining protrusion formed with the outer surface thereof. A resilient retaining member is protrudingly provided on the flat clamp opposite the plate-shaped protrusion or the base and has a hole for engaging with the retaining protrusion. An engaging member is protrudingly provided on the same surface with the resilient retaining member in parallel and engaging with an inner surface of the plate-shaped protrusion. Further, a notched portion formed with a distal end of the resilient retaining member faces the engaging member. Therefore, the cable clamp can easily carry out unlocking without any unlock levers and offers not only a simple but a secure locking mechanism.

    • A video synchronous detector apparatus for discriminating a video intermediate frequency signal, in which the video intermediate frequency signal is divided into two parts, one of which is applied to one terminal of a multiplier circuit, and the other of which is applied to the other terminal of the multiplier circuit through a picture-carrier intermediate frequency extraction circuit having a frequency selection circuit and a limiter circuit. The frequency selection circuit is provided with a trap circuit. The trap circuit has a center resonance frequency equal to a differential frequency between a picture-carrier intermediate frequency (f.sub.p) and a differential frequency between a color subcarrier intermediate frequency (f.sub.c) and a sound-carrier intermediate frequency (f.sub.s) so that a so-called sound-cross-color disturbance caused by a beat between the intermediate frequency sound signal and the intermediate frequency picture signal may be reduced.
