Title: Method for producing denture mold and structure thereof
Inventor: SHIU HAN-JUNG
IPC: A61C13/34
Filed: 2003-07-17
Granted: 2004-12-11
Abstract: The present invention provides a method for producing a denture mold and a structure thereof. The invented method mainly comprises: obtaining a teeth mold from a gum portion of a patient where tooth/teeth are missing and the teeth on the two sides thereof; inserting a hollow tube with sealed ends into the gum mold, where tooth/teeth being missing, of the patient; cutting the gum mold to separate the gum mold from the teeth mold in order to split the hollow tube in the gum into two portions such that the base and the tooth/teeth missing portion of the gum mold are respectively formed with a slot hole for the insertion of a positioning post. The positioning post has a length identical to the inside diameter of the hollow tube. Thus, when the separated gum is put back to the original position, the height and corresponding location thereof are identical to the status before obtaining the mold. By separating the gum mold from the teeth mold, the teeth on the two sides of the tooth/teeth missing portion are exposed for the convenience of a technician in trimming and repairing the base of teeth and denture, as well as observing the tightness between the denture and the teeth mold. As a result, when a produced denture is mounted on the teeth of a patient, no error is produced by the separation of the teeth mold, thereby achieving the effect of an accurate production.

Title: Enhanced security catch assembly for retaining a handle on a spindle
Inventor: SENGER CHRISTOPHER G
IPC: E05B3/00
Filed: 2003-10-08
Granted: 2007-02-01
Abstract: A catch assembly that locks a handle onto the spindle of a lock mechanism has enhanced resistance to attempts to remove the handle by forcibly driving the catch assembly inwards. The catch assembly includes a base mounted on the spindle having a threaded opening that receives a corresponding threaded retaining pin. The pin is moved axially by rotating it. When the pin is rotated to an outward position it engages the handle and the threads act to prevent the pin from being forcibly driven inward by transferring axially applied forces to the base. In the preferred design, the head of the retaining pin is softened and specially shaped to limit the torque that can be applied.

The inspecting signal generated by each sensing plate is subtracted through the use of the subtractor 550; and the inspected value generated by one of the sensing plates is divided by the subtracted result through the use of a divider 560. In addition, the inspected value generated by one of the sensing plates is normalized. The ratio of the relative inspecting signal values generated by both sensing plates is then detected; and the inspected result corresponding to the distance between the sensing plate and the conductor 520 is used as X to obtain the conductor position.

Title: A method for detecting the burning of the gas burner
Inventor: YANG KUAN-RUNG
IPC: F24C3/12
Filed: 2004-05-18
Granted: 2005-03-21
Abstract: The present invention is to provide a kind of method for detecting the burning of the gas burner including setting up the inspection temperature in the CPU. When the current temperature is higher than the inspection temperature (14), the CPU will calculate the settling time (16) and the variation of the current temperature (22) until the variation of the current temperature corresponds with the setting variation range of temperature (22) and the settle time corresponds with the first setting time (24). The CPU can read the setting and set mode to be ""general cooking"" or ""water heating"". Under ""general cooking"" mode, the gas burner is set to extinguish when the current temperature is higher than the second burning temperature (30). Under ""water heating"" mode, the gas burner is set to turn the stove fire weaker (26') and extinguish (28') after the settling time is longer than the two specific time periods (26')(28'). The gas stove extinguishes immediately when the current temperature is higher than the first burning temperature (18) or the second burning temperature (30).

Title: Fastener driving tool having contact arm in contact with workpiece
Inventor: NAKANO YOSHIHIRO
IPC: B25C1/00
Filed: 2004-06-18
Granted: 2005-09-21
Abstract: A nail gun having a contact arm normally biased in a direction away from a workpiece by compression springs. A free end of the contact arm is brought into abutment with a workpiece and a trigger is pulled for driving a nail thereinto. In the trigger pulling operation, an inner end of the contact arm is engaged with a trigger arm which is biased by a plunger spring through a plunger. Because the contact arm is held on the workpiece, the plunger is moved to provide ON state against biasing force of the plunger spring. Immediately after the nail driving, a nail gun body is moved in a direction away from the workpiece relative to the contact arm. This causes disengagement of the trigger arm from the inner end, to relatively move the nail gun body toward the workpiece by the biasing force of the compression springs. This means relative movement of the contact arm in the direction away from the workpiece. If the trigger is released, the trigger arm is again brought into engagement with the inner end, because the trigger arm is normally urged toward the inner end by a trigger arm spring.
