In continuous printing operation which repeatedly sets a state in which when a preceding printing material passes through the nip area of a thermal fixing unit, a succeeding printing material has been supplied to an image forming unit and image forming operation has been started, a first temperature indicating an ambient temperature near the thermal fixing unit is measured at an early time point in the continuous printing operation. A second temperature indicating the temperature of the printing material which has passed through the press contact nip portion at a predetermined period of time during the continuous printing operation is measured. The amount of heat to be supplied to the succeeding printing material is controlled on the basis of the measured first and second temperatures.

The invention discloses a method for correcting an electronically programmable fuse wire device, which is suitable for an electronically programmable fuse wire device. The electronically programmable fuse wire device comprises two polysilicon electrodes and an electronically programmable fuse wire connected between the electrodes, wherein the electrodes and the electronically programmable fuse wire are positioned on a substrate; sub-resolution additional patterns are added at both sides of the electronically programmable fuse wire; and the sub-resolution additional patterns are used for changing the characteristic dimension of the electronically programmable fuse wire. The invention has the following beneficial effects: by adding the sub-resolution additional patterns, different characteristic dimensions can be formed in the polysilicon fuse wire, so that different current densities can be formed, and the electric migration phenomenon of the electronically programmable fuse wire can be enhanced, thereby enhancing the fusing performance of the electronically programmable fuse wire device.

This invention provides a temperature fuse with resistor substrate and a secondary protection circuit, film electrodes on two sides and a middle film electrode are disposed on surface of the substrate, aforementioned electrodes are widely disposed, and the fuse element, fuse element part (m) between film electrode (a) and the middle film electrode, fuse element part (m) between film electrode (b)and the middle film electrode are also disposed thereon, film resistors leading the fuse elements to blow out via conduction heat are disposed on other surface of the substrate, so that each fuse element can blow out in optimization reliably and partly relative to another fuse element. Thus, distance between fuse element (m) and the film resistor (r) is different from distance of film resistor (r) of the fuse element part (m).

The invention belongs to the technical field of steel wire rope processing, in particular to a fuse machine for production and processing of steel wire ropes, including a processing table and a fuse machine body, the top outer wall of the processing table is equidistantly connected with mounting plates, and each adjacent two The opposite outer wall of each mounting plate is fixedly connected with the same ring frame, the outer wall of the ring frame is fixedly connected with a cooling tube, and the outer wall of the cooling tube above is provided with a sliding groove. The present invention is provided with a preheating box, an electromagnetic heater, an arc-shaped limiting plate and a heat-conducting rod. At the position plate, the internal interference heat conduction frame inside the arc-shaped limit plate transfers heat to the steel wire rope, thereby pre-heating the steel wire rope to ensure that when the steel wire rope is cut inside the fuse machine, the steel wire rope is in an easy-to-cut state as a whole, and the safety of the fusing point is improved. Fuse effect.

The invention relates to a flux and a temperature fuse with the flux, wherein the flux is formed by mixing common rosin, stearic acid, liquid alcohol and minim small molecule acid in the following mixing ratio (weight percent): 50 percent to 70 percent rosin, 5 percent to 20 percent stearic acid, 10 percent to 40 percent liquid alcohol and 0.5 percent to 16 percent small molecule acid. The temperature fuse element comprises an electrode slice (1), an insulation bottom film (21) and insulation upper film (22), the flux (3) and a lower melting point alloy wire (4). Compared with the prior flux,the flux of the invention obviously improves the thermal-link performance and does not decompose during storage, and well maintain the activity of the flux. The thermal-link performance of the temperature fuse element used by lithium ion cell produced by the invention is obviously improved, thus forming better protection for lithium cell.

The invention relates to the field of welding technology, in particular to a welding process method for dissimilar metal parts. It is used for welding between stainless steel workpieces and aluminum alloy workpieces or between low carbon steel workpieces and aluminum alloy workpieces, including the following steps: use the first welding wire to overlay the transition layer in the base metal welding area of ​​the stainless steel base, and the arc is deflected to the welding wire during welding; The second welding wire is used to melt and weld between the surfacing transition layer and the aluminum alloy base material, and the arc is biased towards the aluminum alloy layer during welding; after welding, the weldment is placed in a heat preservation furnace for heat preservation, and is cooled with the furnace after heat preservation for a preset time. Using the welding process method for dissimilar metal parts provided in the present invention, because the transition layer is first welded in the base metal welding zone of the stainless steel base layer in the welding process, and then the transition layer is welded with the aluminum alloy base material, the transition layer and the aluminum alloy base material can be welded. The melting point of the aluminum alloy base material is kept within the same range to ensure uniform composition of the weld after welding and no serious deformation of the weld.
