Abstract: Provided are a semiconductor device and a method for manufacturing the same, and a semiconductor package. The semiconductor device includes a die stack and a cap substrate. The die stack includes a first die, second dies stacked on the first die, and a third die stacked on the second dies. The first die includes first through semiconductor vias. Each of the second dies include second through semiconductor vias. The third die includes third through semiconductor vias. The cap substrate is disposed on the third die of the die stack. A sum of a thickness of the third die and a thickness of the cap substrate ranges from about 50 ?m to about 80 ?m.

Abstract: An immersion cooling system includes a pressure seal tank, an electronic apparatus, a pressure balance pipe and a relief valve. The pressure seal tank is configured to store coolant. A vapor space is formed in the pressure seal tank above the liquid level of the coolant. The electronic apparatus is completely immersed in the coolant. The pressure balance pipe has a gas collection length. The first port of the pressure balance pipe is disposed on the top surface of the pressure seal tank. The relief valve is disposed on the second port of the pressure balance pipe. The second port is farther away from the top surface of the pressure seal tank than the first port. The gas collection length of the pressure equalization tube allows the concentration of vaporized coolant at the first port to be greater than the concentration of vaporized coolant at the second port.

Abstract: A covering lock for an automobile steering wheel includes a cover and an anti-theft rod. The cover has a circumferential U-shaped hook to hook around the steering wheel of a car and the anti-theft rod able to be locked with the cover and extending rearward to prevent the steering wheel from rotated. Then the covering lock not only locks the steering wheel but also prevents a safety air bag fixed on the steering wheel from stolen.

Abstract: A lock housing for an automobile steering lock device has a heat-treated, very hard protective cylinder between a cylindrical wall of the housing and the lock. The lock has a rod-shaped dead bolt extending in a same-shaped hollow space in the housing to extend into one of the grooves in an elongate rod member to immovably lock the rod member in an elongate tubular member in any one of a plurality of positions.

Abstract: A card lock and a punchable key card having a key card having through holes in the coordinating locatins to and the same number as long pin tumblers provided in a card lock for unlocking the lock without electric power, and a card lock having a plurality of pin tumblers--some long and some short mixed regularly or irregularly--and a dead bolt mover having through holes for the pin tumblers to fit and move is disclosed. The key card functions to push up the short pin tumblers to make the upper ends of all the pin tumblers become positioned in the same level as the upper surface of the dead bolt mover so that the dead bolt mover can be pushed further inward from the locked position to the unlocked position by the key card to retract the dead bolt to unlock the card lock.

Abstract: An anti-theft device for attachment to a steering wheel of an automobile comprising a U-shaped solid pressing rod, two vertical elongated pinching plates welded in parallel with two ends of the U-shaped rod, a socket having a passageway for an insertable lock to insert therein and a insertable lock having one or more elastically retractable projections and an extensible rod. The two vertical pinching plates are placed to pinch a portion of a steering wheel of an automobile and the lock is to be inserted in the passageway in the socket, with the projection(s) engaging the notch(es) in the end surface of the socket and the end of the extensible rod engaging the through hole in the rear pinching plate to lock this device by turning a key inserted in the lock.

Abstract: A car lock to be mounted on the steering wheel comprising a handle with a front grooved section, a tubular lock base comprising a hollow passage linked with a tube linked with a screwed rod, and a lock fixed on the lock base. A hook is fixed on the handle to be hooked on the steering wheel to keep it from turning around with help of the screwed rod. The handle has its front grooved section mounted for movement in the hollow passage and the tube of the lock base, and can be pulled down in relation to the lock base to position the hook on the steering wheel and then lock the lock, whose dead bolt then sticks in one of the grooves in the grooved section of the handle making the steering wheel impossible to turn.

Abstract: An extensible car lock comprising a lock handle and an extensible rod assembled with the lock handle and inserted extensible in the interior of the lock handle such that the whole length of the car lock can be adjusted by pulling the extensible rod outward or inward to mount this car lock on the steering wheel with help of two hooks provided on the lock handle and the extensible rod, and then the dead bolt of the lock provided at the front end of the lock handle can be extended through a hole in the lock handle and one of the plurality of dead bolt holes in the extensible rod for locking the car lock on the steering wheel.
