A reduction gear capable of satisfying, at high level, each of: realizing a high reduction ratio; preventing backlash by securing rotation smoothness; and carrying out compactification and weight saving of entire mechanism is provided. The reduction gear of the invention is a modified crown reduction gear, comprising: a pressing mechanism 16 operated to rotate; a fixed crown gear 2 fixed to an external member 15; a movable crown gear 1, wherein the difference in the number of teeth between the gears is one; and an output axis 3 flexibly attached to the gear 1. The gear 1 engages with the gear 2 at a slant by pressing-force provided from the mechanism 16. In this instance, contact locations of teeth of the gears 1 and 2 are dispersed at two places existing at both sides between which a gradient center line intervenes.

A vehicle body rear part structure improved against rear-side collisions is disclosed. The rear part of a vehicle body includes left and right rear side frames; a front cross member and a rear cross member, both extending between the left and right rear side frames; and a bar and a bracket. The rear cross member has arm support parts for supporting lower arms of left and right rear suspensions on a center part which is lower than lateral ends of the vehicle body. The bar is curved in a convex manner toward the bottom of the vehicle body, and the bar connects center parts of the front and rear cross members together. The bracket mounts a rear end of the bar to the rear cross member while enclosing the rear end from the bottom of the vehicle body.

A high-shear melt-kneader includes a high-shear unit (20) having an internal feedback-type screw (23) configured to apply high-shear stress to a melted resin, resin pressure sensors (33) for configured to detect a front portion resin pressure in the vicinity of an inlet of the internal feedback-type screw and a rear portion resin pressure in the vicinity of an outlet, and a control device configured to appropriately control a material supplying amount, a material temperature, a kneading time, and a screw rotation speed according to pressure values detected by the sensors. The control device controls the conditions such that waveforms with the lapse of time of the front and rear portion resin pressures are similar to each other and show variation to a steady state after formation of a predetermined peak value, and the front and rear portion resin pressures form a predetermined pressure difference with the lapse of time. According to the high-shear melt-kneader, it is possible to improve high-shear efficiency, increase precision of nano dispersion of a material, and stably and finely disperse/mix internal structures of immiscible polymer blend-based, polymer/filler-based and polymer blend/filler-based materials to a nano level.

A double-sided printing apparatus using a double sided printing with one plate cylinder and one pressing means system, that is capable of carrying out double-sided printing simply and at low cost, with little deviation in the position of the printed image and with satisfactory resist. Printed matter with little deviation of the image position with respect to the sheet position and with good resist can be obtained, by eliminating delay in feeding sheets due to slippage between roller and press roller by operating the transport belt on the upstream side, and so on, and by eliminating resistance during sheet transportation due to contact with the guide member provided along the circumferential surface of the press roller, when pressing sheets against the press roller with a roller or the like, and transporting the sheets along the guide member or the like provided along the peripheral surface of the press roller. After the resist roller has eliminated the contact between the sheet and the stopper, the transport belt starts to be driven. If the printing speed is low, this timing is taken as the timing that the resist roller contacts the press roller. For both low speeds and high speeds, this may be after passage of a predetermined period of time from the operation command signal for the resist roller.
摘要:
An object of the present invention is to provide a three-dimensional cam mechanism, which is capable of selecting a cam guide surface shape freely to drastically improve the degree of freedom for selecting a target locus on the follower side, transmitting not only a power between orthogonal axes but also a strong and reliable power, and performing a reversible operation. The present invention is configured such that a three-dimensional cam guide surface (2 (3)) is formed in a three-dimensional cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the three-dimensional cam (1) is translated into the swinging movement at the other end of the follower side link (4). As a result, the cam guide surface shape can be selected freely to drastically improve the degree of freedom for selecting the target locus on the follower side, and smooth operations of the three-dimensional cam can be obtained not only by the selection of the shape of a supporting member but also by the free design of the cam guide surface shape, without being neither limited to the power transmission between the orthogonal axes nor followed by the backlash.
