The invention relates to a rainproof structure capable of reducing the equipment manufacturing cost and saving the use space used in a silencer and an exhaust silencer adopting the structure. The rainproof structure is characterized in that a water discharge mechanism is arranged on the top inside a machine case of the silencer and consists of a hollow case, a rectifying net, a rain blocking plate and a water discharge pipe, wherein the water discharge pipe is used for guiding out accumulated water on the rain blocking plate, and the upper end of the rectifying net is also fixedly connected with a rain guide component. The rainproof and rain discharge structure is arranged inside the machine case of the silencer, the function of the silencer for reducing the noise is not influenced, the external use space is also saved, and in an integral aspect, the cost is not greatly increased under the condition of adding new functions, so the equipment manufacturing cost is effectively reduced. The rainproof structure and the silencer have the advantages that the structure is simple, the layout is reasonable, the installation is convenient, the multifunction of a diesel engine for a boat is realized, the boat manufacturing cost is also reduced, and the space utilization rate of boat equipment is also reduced.

The hand-held tool in improved structure has one main body, which has knurled part formed in at least one edge for both antiskid and distinction. The present invention has industrial application value.

This is provided a method for preventing leaking of molten metal from a nozzle in an injection apparatus provided with a plunger within a cylinder body, a supply opening formed in an upper portion of the cylinder body, and a furnace for melting and holding the metal material provided on a top portion of the injection cylinder and having an outlet at the bottom end of the furnace communicated with the supply opening. The method comprises the following steps: metering the molten metal by travel of the plunger head backward from the most forward position to the backward position at the rear of the supply opening while maintaining nozzle touching after completion of an injection step and supplying the molten metal from the furnace into the cylinder body through the supply opening, after completion of the metering, closing the supply opening by travel of the plunger head forward at low speed from the backward position to a stand-by position ahead of the supply opening for cutting off the communication between the molten metal in the cylinder body and the molten metal in the furnace.

An inkjet recording apparatus includes color inkjet heads 11, 12, 13, 14, 15 and 16 and a white inkjet head 17 arranged in different positions with respect to a secondary scanning direction. When recording an image in a pre-white process, a recording medium S is moved in a direction of arrow A. When recording an image in a post-white process, the recording medium S is moved in a direction of arrow B. Thus, the inkjet recording apparatus is simple in construction entailing no increase in the cost of the apparatus, and yet is capable of selectively performing both the pre-white process for printing in white ink first, and then printing in color inks, and the post-white process for printing in color inks first, and then printing in white ink.

The present invention relates to a medicine extraction and purification technology, in particular, it provides a technical method for efficiently separating tetrandrine and B at the same time; that is, using methacrylic acid, ethylene glycol dimethacrylate and azobis Isobutylcyanide and other target molecular powders tetrandrine and B are synthesized, and then the target molecule is eluted to obtain a double-template molecularly imprinted polymer. The column and preparative chromatograph further separate the tetrandrine and B, and the purity of the obtained tetrandrine and B reaches more than 99%.

The method comprises: setting up and electrically-connecting at least on semiconductor chip; through an electrical connection structure composed of an upper layer circuit board and lower layer circuit board, the semiconductor chip is connected to the baseboard; said semiconductor chip is held by a holding space in the electrical connection structure; forming a sealing gel used for covering the semiconductor chip and the electrically connection structure; after completing the forming of sealing gel, multi weld pads are exposed from the sealing gel in order to make at least one semiconductor component electrically connected to the upper layer circuit board so as to form a stack structure.

The invention relates to use identification and timing for use of a breaking hammer in an engineering machine, aims at solving the problem of inaccurate timing for use of a breaking hammer in an engineering machine, and provides an identification and timing system, and an identification and timing method for a working condition using a breaking hammer in an engineering machine. The identification and timing system comprises a vibration sensor for measuring vibration, a main pump pressure sensor, an installation boom movement induction device and a control unit, wherein the control unit receives measurement values of the vibration sensor, the pressure sensor and the induction device, and judges a working state of the engineering machine; and a timer carries out accumulative timing when the engineering machine is under an impact working condition using the breaking hammer. The system disclosed by the invention is simple and reliable, and capable of accurately accumulating a working time of the working condition using the breaking hammer. In addition, only the vibration sensor is added relative to the original machine, thus the cost is basically not increased.

The invention discloses a making method of heatproof hard polyurethane foam, which is characterized by the following: adopting composite technique of multiple polyethers / polyester polyol with high functional degree (fn:5-6) or heterocyclic structure in the molecular chain segment; making the aromatic ring structure material of polyester polyol as reacting monomer; allocating polyether polyol and polyester polyol according to certain proportion; reacting under catalyst, foamer, uniform foaming agent and PAPI with the index of isocyanate at 1. 05-1. 10; synthesizing PUF foam.

The invention relates to an excavator, and provides a bogged-down condition detection system for the excavator to safely detect whether a bogged-down condition risk exists in a construction position of the excavator. When the excavator detects whether the bogged-down condition risk exists in the construction position, a bucket baseplate is flatly placed in the construction position to be detected,a boom cylinder is retracted to sink a bucket into the ground till the boom cylinder cannot be further retracted, a controller calculates an acting force onto the plane of the bucket baseplate from the ground and the sinking depth of the bucket according to a detected parameter value, the maximum ground pressure which can be borne by the construction position and the permitted sinking depth of the whole machine are compared in combination with area calculation of the plane of the bucket baseplate to judge whether the construction position can lead to a bogged-down condition of the whole machine, and a judgement result is displayed on a display. The bogged-down condition detection system can accurately judge whether the bogged-down condition of the whole machine can occur in the construction position or not under the condition of guaranteeing that the whole machine is away from a dangerous position, and a driver is reminded, so that the probability of an accident is effectively reduced.
