Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

Abstract: A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

Abstract: The present invention relates to a variable tumble flow-generating device, which comprises: a bulkhead for dividing an intake port into a first passage and a second passage; an opening degree control valve for selectively changing an opening degree of the first and second passages; and driving means for operating the opening angle control valve. This variable tumble flow-generating device can generate tumble flow by making air flowing through different passages while minimizing a flow resistance of air supplied into the combustion chamber, and which has a simple structure so that a limitation in its installation space in relation with other parts can be avoid. Also, the variable tumble flow-generating device is manufactured by adding only a structure where the bulkhead is previously assembled with the intake port core of the prior art. For this reason, this is a simple structure and thus is manufactured at inexpensive costs.

The variable tumble flow-generating device can generate tumble flow by making air flowing through different passages while minimizing a flow resistance of air supplied into the combustion chamber, utilizing a simple structure limiting installation space in relation with other parts. The variable tumble flow-generating device is manufactured by adding only a structure where the bulkhead is previously assembled with the intake port core of the prior art. For this reason, this is a simple structure is manufactured inexpensively.

Abstract: An engine is provided having a cylinder head and a cylinder block. The cylinder head has a head water-jacket for circulating coolant, and the cylinder block has a block water-jacket for circulating the coolant. Coolant flow is blocked between the block and head water-jackets except through a primary pathway or an additional one or more secondary pathways. First and second thermostats are equipped to respectively control coolant flow from the head and block water-jackets, such that the coolant flow through the head and block water-jackets are respectively controlled based on respectively preset temperatures of the first and second thermostats.
