  • Publication number: 20110089025
    Abstract: The present invention relates to a method for manufacturing a chip resistor having a low resistance. The method includes the following steps: (a) providing a substrate having a top surface; (b) sputtering a conducting layer directly on the top surface of the substrate, so that the conducting layer and the substrate contact each other, wherein the material of the conducting layer comprises nickel or copper; and (c) plating at least one metal layer directly on the conducting layer, so that the metal layer and the conducting layer contact each other, wherein the material of the metal layer comprises nickel or copper, and the conducting layer and the metal layer provide a resistive layer. As a result, the resistive layer has a precise pattern, and the duration of sputtering is reduced, so the yield rate and the efficiency are improved and the manufacturing cost is cut down.

  • Publication number: 20100201477
    Abstract: The present invention relates to a chip resistor and method for making the same. The chip resistor includes a substrate, a pair of bottom electrodes, a resistive film, a pair of main upper electrodes, a first protective coat, a pair of barrier layers, a second protective coat, a pair of side electrodes and at least one plated layer. The first protective coat is disposed over the resistive film, and covers part of the main upper electrodes. The barrier layers are disposed on the main upper electrodes, and cover part of the first protective coat. The second protective coat is disposed on the first protective coat, and covers part of the barrier layers. The plated layers cover the barrier layers, the bottom electrodes and the side electrodes. As a result, the chip resistor features high corrosion resistance.

  • Publication number: 20070262273
    Abstract: A drug counter comprises a body having an upper utensil and a lower utensil; a surface of the upper utensil having a plurality of drug holes; one side of the lower utensil having an opening for receiving the sliding plate; a sliding plate being insertable into the lower utensil from the opening at one side of the body; the sliding plate resisting against a lower side of the drug holes of the upper utensil. In use, the drugs are placed upon a surface of the upper utensil. The surplus drugs are driven to the upper utensil. The sliding plate can be driven to move according to the amount of the drugs so that the drugs in the drug holes fall into the lower utensil. The drugs falling into the lower utensil further fall into the drug bag so as to count the number of the drugs.

  • Patent number: 6376073
    Abstract: A high frequency-resistant thermosetting coating is provided for the manufacture of high frequency-resistant enamelled wires. A high frequency-resistant enamelled wire produced from the high frequency-resistant thermosetting coating is also provided. The adhesion, crosslinking density, abrasion resistance, and softening resistance of the coating are excellent. With the same nominal diameter and a coating thickness more than 85 &mgr;m, the high frequency resistant lifetime of the enamelled wire produced from the high frequency-resistant thermosetting coating is 3 to 4 times as that of conventional thermoplastic enamelled wires.
