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.

    摘要: An automatic focusing system for a video camera carries out automatic focusing on the basis of a focus signal extracted from a high-frequency component of a video signal. The automatic focusing system comprises at least one of picture-contents change detecting means for detecting a change, if any, between the contents of pictures of two consecutive picture periods on the basis of the output signal of a low-pass filter to which the video signal is applied, momentary change detecting means for detecting an abrupt change of the focus signal, and reduction-factor change detecting means for detecting a change between the contents of pictures of two consecutive picture periods on the basis of the output signal of a detector detecting the reduction factor of the lens system, so that the automatic focusing operation can be interrupted in response to the output signal of the change detecting means and can be restarted when the output signal is reduced to a level lower than a predetermined level.

    摘要: 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.

    摘要: 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.

In addition to Fe, C, Si, Mn, P, S, N, and Al, the steel sheet contains V or at least one element of Nb, Ti and Zr. The contents of the at least one element of Nb, Ti and Zr, if present, satisfy the expression of [% C]−[% Nb]/92.9×12−[% Ti]/47.9×12−[% Zr]/91.2×12>0.03. The steel sheet has an area ratio of tempered martensite of 50% or more with ferrite as the remainder. The number of precipitates having a circle-equivalent diameter of 1 to 10 nm is 20 particles or more per 1 μm2 of the tempered martensite. The number of precipitates containing V or the at least one element of Nb, Ti and Zr and having a circle-equivalent diameter of 20 nm or more is 10 particles or less per 1 μm2 of the tempered martensite.
