Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

Abstract: A water control valve with offset valve core has a main body with a flowing slot, the circumferential wall of which is formed with a water inlet and outlet. An offset rotary valve core is configured offset inside the flowing slot and has a rotary shaft and a water stopping seat. The face of the water stopping seat faces the circumferential wall and has a sealing ring. When the water stopping seat rotates along with the offset rotary valve core and is aligned with the inlet, the sealing ring is pressed against the circumferential wall to close the inlet, thus forming the water stop mode. The rotary shaft and the circumferential wall of the flowing slot define a flowing space. The flow from the inlet must pass through the flowing space and exit through the outlet. A dialing component is used to connect and drive offset rotary valve core.

Abstract: A swing type wheel locking device includes a wheel axle and a pivoting part. A wheel body has an outer wheel face and an axle hole fitted on the periphery of the wheel axle at a position close to the axle end part. A plurality of positioning concave parts are arrayed in a circle on the outer wheel surface. A swing type wheel locking component is pivoted on the wheel axle and has a pivoting end and a swing section. The pivoting end is pivoted on the pivoting part, so that the swing section can be forced to swing, and by choosing different swing angles, it can be shifted between a locked position and released position. When a clamping convex part of the swing section is at a locked position, it is locked right inside the corresponding positioning concave part. Thus, the wheel body is locked against rotation.

Abstract: A mode-locked solid state laser apparatus including an optical film, a gain medium crystal, a Fabry-Perot element, a first mirror, a second mirror, a third mirror and an output coupler is disclosed. The optical film is configured to receive a pumping light having a first wavelength incident in a first direction. The gain medium crystal receives the pumping light passing the optical film, and generates an initial laser beam having a second wavelength, wherein the initial laser beam forms a first optical path starting at one end thereof from the gain medium crystal. The Fabry-Perot element is disposed on the other end of the first optical path opposite to the one end, and reflects the initial laser beam along a second optical path having one end thereof starting from the Fabry-Perot element.

Abstract: An impingement sprinkler includes a main frame, a sprinkling device laterally pivotally mounted onto the main frame, an impinging device rotatably mounted on the sprinkling device, a reversing device disposed on the sprinkling device and a limit device is mounted to a lower portion of the main frame, wherein the limit device is operated with reversing device to limit the horizontally rotary angle and accurately control the irrigating area of the impingement sprinkler

Abstract: An expandable house includes multiple flexible hoses and a connector provided to connect every two flexible hoses that longitudinally correspond to each other for forming a tubular structure. The tubular structure has two opposite ends each having a coupler longitudinally mounted thereon. The two couplers are respectively connected to a faucet and a water sprayer. Each flexible hose includes an inner tube and an outer tube sleeved on the inner tube, wherein the inner tube and the outer tube are synchronously longitudinally expanded to enhance the total length of the tubular structure due to a water pressure acted on an inner periphery of the inner tube. The tubular structure longitudinally shrinks to its original length for an easy storage when the water source is closed and the water pressure acted on the inner periphery of the inner tube is disappeared.

Said retaining plate has a sleeving portion, arranged at a preset location of the retaining plate. With the sleeving portion, said retaining plate could be set on the water manifold to rotate by taking the water manifold as its axle center. Multiple abutting portions are formed onto periphery of the retaining plate. When the foot stands of the sprinkler tripod are in expanded state, the retaining plate is rotated such that the abutting portions are mated with the foot stands, and the foot stands can be abutted onto the abutting portions for secure support. Multiple openings are set at one side of the abutting portions of the retaining plate.

The tightness of a resilient unit can be adjusted by the user through the action unit, and a secured positioning is formed by the engagement of restricting protruding ribs of the inner plate and positioning protruding ribs of the receiving space to prevent the resilient unit from rewinding after adjustment to effectively adjust the tightness of the resilient unit and swing unit, and increase variability, as well as practicability and convenience of the sprinkler.

Abstract: An impingement sprinkler is provided wherein the first and second limiting pieces of the rotation limiting mechanism are configured with first and second stopping portions extending along the swinging path. As such, when the main body slants upward or downward, the poking rod portion can always contact the first and second stopping portions. Therefore, the first or second limiting pieces can interfere with the poking rod portion and maintain the function of the main body to shift turning directions. In this way, no matter whether the main body slants upward or downward, it can substantially execute the turning action to sprinkle the surroundings. Hence, the practical utility and usage convenience of the product is greatly enhanced.

The tilting regulator is arranged between the support of main body and the tubing portion on the lower end of the main body, so that the main body can be tilted to change the outflow angle of sprinkler head. The guiding member is located on the support of main body, driving the steering of the main body. The steering control member is installed on one side of the support of the main body to change the rotational direction of the main body. When the main body is tilted, the poke rod of steering control member could be maintained into the limiting ring frame, so that the first or the second limiting member could intervene the poke rod to make the main body retain the steering action.
