The invention relates to a heat radiation die set and a radiation system applying a phase change metal thermal interface material. The heat radiation die set and the heat radiation system can ensure that heat generated by the operation of an electronic element can be rapidly transmitted to outside environments. The heat radiation die set comprises a radiator and a phase change metal thermal interface material (TIM), wherein the radiator is arranged above the electronic element, and the bottom surface of the radiator is at least provided with a slot. The phase change metal thermal interface material is arranged between the electronic element and the bottom surface of the radiator, and is used as a thermal interface material between the electronic element and the radiator. When the phase change metal thermal interface material is melted by heating, part of hot melting liquid can flow into the slot so as to prevent the superfluous hot melting liquid from leaking out of a thermal interface.

The invention discloses an extrusion forming method for magnesium alloy housing type component ring ribs. The extrusion forming method comprises the following steps of: (1), placing a processed hollow blank in a barrel-shaped hollowing block; (2), symmetrically arranging at least two split terrace dies in an inner tube of the hollow blank, moving the split terrace dies in the radial direction, respectively extruding the inner tube wall surface of the hollow blank by extrusion bulges of the split terrace dies, forming a certain vacancy between the extrusion bulges of the two split terrace dies, enabling un-extruded part of the inner wall of the hollow blank to plastically flow towards the vacancy between the extrusion bugles to form radial bulges, and automatically returning the split terrace dies; and (3), rotating the split terrace dies by a certain angle to reach positions at which the extrusion bulges of the split terrace dies correspond to the radial bulges, circulating the extrusion operation in the step (2), retracting the extruded split terrace dies, extruding the ring ribs at the periphery, repeating the operations when the split terrace dies reach the position of the next ring rib, and finally forming the qualified housing component with the ring ribs.

A detachable connector is provided in which a male connector unit mounted to a movable panel is attachable to and detachable from a female connector unit mounted to a main body. In a pair of first and second female terminals, the first female terminal which has a longer distance to an axis of rotation of the movable panel includes a sloped portion for being elastically in contact with a leading-end corner of a convex contact of the male connector unit from obliquely above, and the second female terminal includes a contact portion for being elastically in contact with the side surface of the convex contact from below. When the male connector unit is attached to the female connector unit, the sloped portion is in contact with the convex contact at a position that is more distant from the movable panel than the contact portion.

The present invention is the technological scheme of mold and method for producing open-mouthed concrete box and solves the technological problems the smooth demolding of the inner formwork inside the open-mouthed concrete box and producing concrete boxes of different heights with the same mold. The mold features that the inner mold comprises four shutterings and four rack spliced together and has intervals between shutterings filled with rack and inserted sheets. The outer mold is also spliced with four formworks and has adjustable inserted strips to control the thickness of concrete box. During demolding, the inserted sheets are first withdrawn, the racks are then withdrawn, and the shutterings may be taken out easily.

A rotary electric shaver including a disc-shaped outer cutter 10, which is mounted in the upper part of a shaver main body housing therein a motor and has ring-shaped tracks 18 on the under (inner) surface thereof, and an inner cutter 12A, which has cutter blades 120 that elastically contact the ring-shaped tracks 18 of the outer cutter 10 from below and is rotated by the motor; and in this shaver, the inner cutter 12A has vibration elements 132 that travel in the ring-shaped tracks 18 and have a smaller spring constant, compared to the cutter blade 120, in the direction same as and opposite from the direction in which the cutter blades travel, and the vibration elements 132 vibrate and produce sound when, during shaving, they strike stoppers 134 provided near the vibration elements 132.

In a variable stroke-characteristic engine for a vehicle, a control shaft and a control link are disposed on a front side of a vehicle body with respect to a crankshaft. An actuator for driving the control shaft is disposed on an outer surface of an engine block on the front side of the vehicle body. Thus, the actuator projects as much as possible from a position of the engine block toward the front side of the vehicle body so that traveling wind from ahead of the vehicle is effectively applied to the actuator to enhance the cooling effect. Hence, any temperature increase of the actuator is suppressed. Moreover, the actuator is disposed as far as possible from an exhaust manifold that is heated to a high temperature by the heat of an exhaust gas.

The present invention discloses a marine escape door. The marine escape door comprises a door frame installed on a cabin, notches being disposed at all four corners of the door frame; an escape door installed inside the door frame and equipped with a lock, a baffle plate being installed at a side face of the escape door, a ring of air sac being installed at one side of the baffle plate and being internally equipped with solid nitrogen particles, and electric detonators being installed at four corners inside the air sac; and a switch being installed in the center of an inner surface of the escape door and connected with the four electric detonators. Through the above method, the marine escape door provided by the present invention is used inside the cabin, a conventional escape door is hard for escape because the cabin door has the characteristics of being excellent in leakproofness, and with adoption of the air sac of the marine escape door, the door and the door frame can be separated, thereby ensuring smooth escape of people.

The invention discloses a graphite die for sintering a multichip. The graphite die comprises a graphite bottom plate (1) and a graphite assembling strip (2); a sintering groove (3) with an opening is formed on the side part of the graphite assembling strip (2); the sintering groove (3) comprises a sintering chamber (4), an upper sintering groove (5) and a lower sintering groove (6), wherein the upper sintering groove (5) and the lower sintering groove (6) are formed on the upper side and the lower side of the sintering chamber (4) and are communicated with the sintering chamber (4); the dimension of the sintering chamber (4) in the length direction and the width direction of the graphite assembling strip (2) is smaller than the dimensions of the upper sintering groove (5) and the lower sintering groove (6) along the length direction and the width direction of the graphite assembling strip (2). According to the graphite die for sintering the multichip, disclosed by the invention, the structure of each part of the upper sintering groove of the graphite assembling strip is designed according to the structure of a design product, so that the chip in each position can be matched with different positions on the sintering grooves, and the chips can be prevented from collapsing during being assembled and sintered; and the graphite die has the characteristics of being simple in structure and convenient to use, and is suitable for popularization and application.

The invention relates to a seat armrest support structure. The seat armrest support structure comprises a mounting bracket fixedly connected to a seat framework and an armrest connected to the mounting bracket in a rotating mode.
