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 power source apparatus, according to an aspect of the present disclosure, includes: a circuit on a primary side constituted so that a first voltage with an input voltage stepped down is formed on the primary side of a transformer; and a circuit on a secondary side including first to N sub-circuits (N is a natural number of 2 or more), each sub-circuit operating to generate a power source voltage of a driver configured to drive a power element through a converter operating based on a second voltage formed on the secondary side of the transformer after the first voltage is transformed by the transformer, in which the power source voltage generated by the sub-circuit is determined dependently on an output voltage of the converter.

The neural network model deployment method may include providing a specification wizard to a user, searching for and training a neural network based on a user requirement specification that is input through the specification wizard, generating a neural network template code based on the user requirement specification and the trained neural network, converting the trained neural network into a deployment neural network that is usable in a target device based on the user requirement specification, and deploying the deployment neural network to the target device.

Abstract: Provided is a duct docking device for a ventilation seat of a vehicle. The duct docking device enables air to be easily blown to a seatback and a seat cushion with a passenger in a seat using only one blower by enabling a seatback duct mounted at the seatback and a seat cushion duct mounted at the seat cushion to be hermetically docked through a connector duct, etc. at an unfolded position of the seatback in which a passenger can sit, and by enabling the seatback duct mounted at the seatback and the seat cushion duct mounted at the seat cushion to be separated from each other at a folded position of the seatback in consideration of that there is no passenger in the seat.

Abstract: The present invention relates to a leaching method of rare-earth metals using a hydrochloric acid from a manganese nodule, and more particularly, to a leaching method of rare-earth metals using a hydrochloric acid from a manganese nodule, in which a manganese nodule is mixed with a hydrochloric acid, then stirred and heated to leach the rare-earth metal included in the manganese nodule.

Abstract: A slit coater with a standby unit for a nozzle and a coating method using the same prevents environmental pollution by solvent steam and simultaneously maintains the slit nozzle in an optimum state. When in standby and not performing a coating application, the slit nozzle is kept in a standby unit having a solvent atmosphere therein. The slit coater includes: a table on which an object to be processed is positioned; a slit nozzle for applying a coating solution onto a surface of the object; and a standby unit into which the slit nozzle is loaded when on standby, and having a shutter at the opening thereof to maintain an inner space in a substantially hermetically sealed solvent atmosphere. The atmosphere in the standby unit is configured to prevent hardening of the coating solution in the slit nozzle and thereby maintain the slit nozzle in the optimum state for providing coating applications.

Abstract: Disclosed herein is a shadow mask for cathode ray tubes. When the width of a smaller hole part of each of slots formed at the shadow mask is defined as Sw, the horizontal distance between the end of a taper-shaped larger hole part facing the panel side of each of the slots, which is adjacent to the edge part of the shadow mask, and the end of the smaller hole part, which is adjacent to the edge part of the shadow mask, is defined as Ta, and the incident angle at which the electron beam passes through each of the slots is defined as ?, the shadow mask has at least one slot through which the electron beam passes at an incident angle ? of above 47 degrees, and the at least one slot through which the electron beam passes at an incident angle ? of above 47 degrees is configured such that the following inequality is satisfied: 1<Ta/Sw<2.
