摘要:
The present invention relates to a VPP voltage generator that generates a stable VPP voltage. The VPP voltage generator of the present invention generates a stable VPP voltage. Therefore, power consumption can be saved, a precharge time of word line can be prevented from increasing and a tRCD characteristic can be improved. It is thus possible to improve the operational performance of semiconductor memory devices.

The present invention relates to a heat-meltable fluoropolymer composite composition having excellent thermal conductivity, gas and chemical liquid barrier properties and dynamic properties such as storage modulus which comprises a heat-meltable fluoropolymer fine powder and a layered-compound organized by treatment with tetraphenyl phosphonium ions. The present invention also relates to a heat-meltable fluoropolymer composite composition having similar properties to those mentioned above which is obtained by a process (I) in which a heat-meltable fluoropolymer composite composition is obtained by grinding and mixing a heat-meltable fluoropolymer fine powder and a layered-compound and a process (II) in which such heat-meltable fluoropolymer composite composition thus obtained is melted and mixed under shear stress by means of a melt-mixing extruder.

An infusion catheter having a distal shaft with an infusion tube extending from a proximal end to a distal end of the distal shaft, and a proximal cannula with an inner dimension and a distal end attached to a proximal end of the distal shaft to define an opening between the inner diameter of the infusion tube and the inner dimension of the proximal cannula. Also, a guidewire tube disposed within the inner dimension and the distal shaft and extending from the proximal end of the proximal cannula to the distal end of the distal shaft. The inner diameter of the infusion tube, the opening, the exterior dimension of the guidewire tube and the inner dimension cooperate and define sufficient cross sectional sizes to allow a treatment agent to be infused between the proximal end of the proximal cannula and the region of interest.

The object of the present invention is to provide an electrode device for high frequency thermotherapy, including a main casing, an electrode needle, a first engaging part, and a guide unit coupled to the engaging part to be longitudinally moved relative to the electrode needle. The guide unit has a guide tube to receive therein the electrode needle to expose a tip of the electrode needle to the outside of an end of the guide tube. Thus, the exposed length of the tip of the electrode needle is varied according to a position that the guide unit is coupled to the engaging part. The electrode device may further include a three-way valve -provided between the main casing and the guide unit to supply a liquid medicine or water t a desired part of a patient body.

Disclosed are a transflective liquid crystal display device and a method for manufacturing the same, capable of simply forming a reflection section and driving a liquid crystal display device with a transmission mode or a transflective mode by using the same array substrate. After preparing the upper substrate, the thin film transistor is formed in the switching region of the upper substrate. Color resin is coated on the thin film transistor, and is developed to form the color filter. The light-shielding layer is formed on the color filter to prevent current from being leaked from the thin film transistor. The lower substrate is formed in such a manner that the lower substrate is spaced by a predetermined distance from the upper substrate. The reflection plate is formed on the reflection section. The transparent electrode is formed on the reflection plate.

A bracket for use in installing a sensor in a vehicle includes a main body portion having one or more screw holes formed therein, and slot portions for receiving and holding end portions of a back plate of the sensor. The slot portions are connected to end portions of the main body portion, and one or more screw holes formed in the main body correspond to one or more screw holes formed in the back plate. When the back plate is fitted into the slot portions, the slot portions restrict movement of the back plate therein.
摘要:
A sweatband used for headwear that is woven of 100% polyester wrap-way and weft-way, made to single or two-ply without any polyurethane or additional stitched portion. The resulting sweatband, which preferably has a width between 25-70 mm and provides excellent sweat absorbing capability, exhibits good elasticity through the structure of the textile without imposing undue pressure on the wearer, with the result that the sweatband may be worn comfortably for long periods of time. The yarn used to produce the sweatband is processed by high temperature and piece dyeing methods and has twist per each certain length.
