Abstract: An electronic package is provided, in which a first electronic module and a second electronic module are stacked via a plurality of first conductive structures and a plurality of second conductive structures, and the amount of solder of the first conductive structures is greater than the amount of solder of the second conductive structures, such that the electronic package can be configured with the first conductive structures and the second conductive structures according to the degree of warpage of the electronic package, so as to effectively disperse the stress to avoid the problem of warpage.

Abstract: An electrothermal module includes a first conductive layer, a second conductive layer, and a heat generating layer. The first conductive layer and the second conductive layer respectively include silver metal. The heat generating layer has a first portion, the first portion is disposed between the first conductive layer and the second conductive layer to form an electrothermal conversion portion of the electrothermal module, and the heat generating layer includes a conductive carbon material.

Abstract: An actuating and sensing module is disclosed and includes a bottom plate, a gas pressure sensor, a thin gas transportation device and a cover plate. The bottom plate includes a pressure relief orifice, a discharging orifice and a communication orifice. The gas pressure sensor is disposed on the bottom plate and seals the communication orifice. The thin gas transportation device is disposed on the bottom plate and seals the pressure relief orifice and the discharging orifice. The cover plate is disposed on the bottom plate and covers the gas pressure sensor and the thin gas-transportation device. The cover plate includes an intake orifice. The thin gas transportation device is driven to inhale gas through the intake orifice, the gas is then discharged through the discharging orifice by the thin gas transportation device, and a pressure change of the gas is sensed by the gas pressure sensor.

Abstract: A device combining magnetic resonance imaging and positron emission tomography for a breast examination is revealed herein to comprise an air pressure source, a servo flow control module, a pedestal disposed under a breast accommodating hole of a breast MRI bed and having a bearing platform for bearing a PET scanner ring thereon, a non-metallic and non-magnetic pneumatic actuator disposed on the pedestal and connected with the servo flow control module, and a movable pulley having a first nylon rope whose one end connects to the bearing platform and the other end connects to a counterweight unit, wherein the bearing platform connects to a displacement measurement unit by a second nylon rope for receipt of a location information thereof and transmission of the same to the servo flow control module for controlling the opening of the servo flow control valve to change gas flows entering into the pneumatic actuator.

Abstract: A non-metallic and non-magnetic pneumatic actuator is revealed herein to have a piston rod and an end cap both made of PTFE, a cylinder made of PTFE and graphite, a cushion, and at least one sealing piece. The non-metallic and non-magnetic pneumatic actuator can work in the strong magnetic fields, electromagnetic interference or metal prohibited environment.

Abstract: A simply structured bi-functional roller skate has a pair of shoe embodiments. Each shoe embodiment is provided with a front securing seat which is a tubular device with a forwardly extended board, and a rear securing seat which is a tubular device with a backwardly extended board. Both the front and rear securing seats are embedded at the front end and the rear end of each shoe embodiment respectively. Each tubular device of the front and rear securing seats is in alignment with an engagement hole so as to permit a first and a second wheel axle each having a proper length to be led therethrough at the front and rear end of a shoe embodiment. Each wheel axle has a knob-ended locking screw at one end and an internally threaded section at the other end so as to permit the knob ended locking screw to be secured to the end of each wheel axle after roller wheels are mounted to the wheel axles respectively.
