Abstract: A mattress system devised to achieve a function of automatic detection, mainly including a mattress having a simple structure; a control unit equipped with a unique user interface for caregivers to simultaneously adjust three major functions, namely, therapy mode, therapy intensity and comfort level; and a connection pipe for supplying air and power. The system is further provided with a built-in auto-setting function to sense the body characteristics of the patient lying on the mattress and determine an effective supporting pressure range for the patient. By detecting a pressure difference representing the body characteristics of the patient lying on the mattress and comparing with the data stored in a built-in database, the system can always provide the patient with not only a well-proved therapeutic effect through the auto-setting function, but also an adjustable comfort level on the patient's request through the user interface.

Abstract: The present invention relates to an injection unit of a two-stage injection molding machine having an injection device and a meter device for providing plastic to the injection device. The injection motor of the injection device is secured to the base and does not move along with the injection linkage member so as to decrease the movement momentum and improve the injection response and acceleration capability. Additionally, the injection device can adopt a plurality of injection motors for meeting the injection capability requirement without employing high power injection motors. The length of the injection molding machines is relatively shortened, thus the problem of the prior arts is solved.

Abstract: A parallelism adjustment device applicable to nano-imprint lithography has an imprint unit, a carrier unit, a parallelism adjustment mechanism, and a driving source. The imprint unit has a first molding plate and an imprinting mold mounted on the first molding plate. The carrier unit has a second molding plate and a substrate mounted on the second molding plate. The parallelism adjustment mechanism has an enclosed resilient film and a fluid filled therein, and is coupled to at least one of the first and second molding plates. The driving source drives at least one of the imprint unit and the carrier unit to form contact between the mold and the moldable layer. The parallelism adjustment device is pressed via the contact to adjust parallelism for the imprint mold and the substrate and uniformly distributes the pressure between the mold and the substrate, making the molding quality of nano-imprint lithography significantly improved.

Abstract: A two-stage injection molding machine having a pressure sensor device is proposed. The two-stage injection molding machine includes an injection part having an injection cylinder, a driving unit, and an injection rod installed in the injection cylinder; a metering part for feeding plastic material to the injection cylinder of the injection part; and a loadcell installed between the injection rod and the driving unit, wherein pressures in the injection cylinder during the feed metering, injection, and packing processes are detected via the loadcell and the pressure sensor rod. As a result, an accurate pressure feedback control is implemented to achieve high precision injection molding quality. And with the two-stage injection molding machine having such a simple structural design, occurrence of signal distortion and delayed response is prevented.

Abstract: An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw. Stationary parts of the motors are fastened on a frame and forward-backward moving unit, not moving during injection and metering. Due to the arrangement of the moving parts and the injection screw on a single axis, moving parts are lessened, and transmission losses are minimized. Since the number of structural parts is low, only the moving parts of the motors move during injection while the stationary parts thereof remain at rest, thus greatly reducing inertia.
