A toy vehicle is provided. The toy vehicle having: a vehicle chassis defining a first interior region; a leg movably secured to the vehicle chassis for movement from a first position to a second position, wherein the leg and a wheel rotatably secured to the leg is extended away from the chassis when the leg is moved to the second position; a spring for providing a biasing force to retain the leg into the first position; and an actuation unit received within the first interior region of the chassis and operably coupled to the movable leg member and a body portion movably secured to the chassis, the actuation unit being configured to overcome the biasing force of the spring and move the leg to the second position when the body portion is moved with respect to the chassis.

A control system of resisting and assisting force for a rehabilitation apparatus includes a motor, a resistance adjustment control device and a motor output force control device. The motor drives the rotating wheels of the rehabilitation apparatus and controls the rotating wheels to produce resistance and power assisting force. The resistance is designed by imitating the frictional force of different road conditions. The motor output force control device gathers the resistance value preset by the resistance adjustment control device. and the force of a patient pushing or pedaling the rotating wheels and then controls the compensation and the output force of the motor to push the rotating wheels. When the resistance is adjusted to become increasingly larger and larger by the resistance adjustment device, the force of a patient's hands or legs will gradually increase and finally able to push or pedal the rotating wheels by himself.

A new method of forming gate conductor lines for a DRAM in the manufacture of an integrated circuit device has been achieved. A semiconductor substrate is provided. Active areas are defined. A gate conductor layer is deposited overlying the semiconductor substrate. The gate conductor layer is patterned to form gate conductor lines. The intersections of the gate conductor lines and the active areas form DRAM transistors. Adjacent gate conductor lines are spaced a first minimum distance in critical regions and are spaced a second minimum distance in non-critical regions. The critical regions are defined as the active areas between adjacent gate conductor lines where bit line contacts are planned. The non-critical regions are defined as areas located between the critical regions and the adjacent gate conductor lines. The second minimum distance is greater than the first minimum distance to thereby decrease the aspect ratio in the non-critical regions to less than the aspect ratio in the critical regions. An insulating layer is deposited overlying the gate conductor lines and the semiconductor substrate. The insulating layer completely fills the non-critical regions without creating voids to thereby eliminate bit line contact to bit line contact shorts without affecting transistor performance.

A wafer ID optical sorting system includes an auto-ID reader, a manual-ID reader and a conveying device, operation of which units is controlled by a monitoring system. The auto-ID reader, connected to the monitoring system, can automatically read and identify an ID and allows the ID to be displayed on the monitoring system. The manual-ID reader, connected to the monitoring system, can fetch the ID image and allows it to be displayed on the monitoring system. The conveying device, connected to the monitoring system, can move the auto-ID reader and the manual-ID reader.

A heating mechanism for zipper forming machines includes a mold base, a support seat, a seat cover, a screw sleeve and a heating element. The support seat has a clearance at a central portion and a heat insulation pad is fitted into the clearance for dividing the support seat into a heating area and a cooling area. The heating element is disposed in the heating area and a cooling element is disposed at the cooling area for enhancing heat energy efficiencies and reducing noise.

A directly driven power swing rod device without dead points includes a control rod provided with a coordinate rod base, two L-shaped frames respectively provided with a hole base having a bearing fixed therein, two motors respectively provided with a position detecting coder for receiving a coordinate message and transmitting it to a control device which is able to control the rotating angles of the motor shafts respectively connected with the two L-shaped frames, a first interacting member inserted through a guide hole of the coordinate rod base and secured with the first L-shaped frame, and a second interacting member having one end inserted in a positioning hole of said coordinate rod base and the other end connected with the second L-shaped frame. Then the control rod may be deflected by the motors for driving a high speed, sensitive response system.
摘要:
A method for forming a bit line of a DRAM memory array is disclosed. The method comprises the steps of: forming an interlayer dielectric over the DRAM memory array; etching the interlayer dielectric to form trenches in the interlayer dielectric, the trenches collectively forming a bit line pattern and having tapered side walls; and depositing a conductive material into the trenches to form the bit line.
