  • Publication number: 20060236825
    Abstract: A socket includes a body having a driving portion, a receiving portion engageable with a rotatable workpiece, a first gear portion capable of being operatively driven by rotation of the driving portion in a fastening direction and an opposite releasing direction, a second gear portion functionally cooperable to drive the receiving portion for rotating the workpiece, the second gear portion being constructed and arranged to engage with and be driven by the first gear portion. The driving engagement between the first gear portion and the second gear portion is released when a torque required to drive the second gear portion exceeds the threshold amount of torque. A biasing member applies a force of engagement between the first gear portion and the second gear portion, and an adjusting member functionally cooperable with the biasing member adjusts a magnitude of the force of engagement to adjust the threshold amount of torque.

  • Publication number: 20060028830
    Abstract: An automobile compound waterproof taillight includes a bottom base, a main light base, a side light base and a sealing cap. A main light set, a license plate light set, a side light set, and a car width indicating light set are all arranged in the bottom base and separated with caps from one another to clearly show which light is used. The interior of the bottom base is filled with waterproof glue to keep all components therein sealed to keep them from getting wet so as to prolong its service life.

  • Publication number: 20060023466
    Abstract: An automobile compound taillight includes a main base, a main light base, a side light base, and a bottom light base. The main light base, the side light base and the bottom light base are respectively positioned in the main base at a front opening, a side opening and a bottom opening and then those openings sealed with a main light cover, a side light cover and a bottom light cover. The main light base, the side light base and the bottom light base respectively have an electric circuit board and plural LED lamps. The electric circuit board of the main light base is connected with an electric system of a automobile, and the electric circuit boards of the side light base and the bottom light base are connected with that of the main light base. Thus, the automobile compound taillight can be used as a brake light, a direction one and a tail one separately.

  • Patent number: 6548348
    Abstract: A process for increasing the surface area of a DRAM capacitor structure via definition of a capacitor in a porous insulator layer, wherein the porous insulator layer is comprised with voids, has been developed. The process features the use of an anisotropic dry etch procedure to form a capacitor opening in a porous insulator layer, exposing a portion of the voids located on the sides of the capacitor opening extending into the porous insulator layer. An isotropic wet etch is then used to enlarge the surface area of the exposed voids, allowing the surface area for a subsequently formed, overlying storage node structure, to be increased.

  • Patent number: 6337551
    Abstract: A control method for dynamically correcting stabilized error of a spindle motor in an optic storage device. The control method comprises the steps of: (a) At first, under the condition that the spindle motor is stable, checking a rotary speed of the spindle motor so that an initial constant offset value is acquired according to said rotary speed, (b) Reading the stabilized error of the system and determining whether the constant offset value should be corrected, (c) Then, using a control mode of section dividing and staged value to modify the constant offset value, and (d) Suppressing the stabilized error to a minimum value.
