The shift control system for an automatic transmission in a vehicle includes a plurality of sensors and a transmission control unit. The plurality of sensors sense operating conditions of the vehicle. The transmission control unit controls shift control solenoids and a pressure control solenoid in a hydraulic control system for the automatic transmission based on the sensed vehicle operating conditions. The shift control solenoids control operation of friction elements in the automatic transmission, and the pressure control solenoid controls hydraulic pressure supplied to the friction elements. The transmission control unit detects a change in driving mode from a reverse mode to a drive mode based on the sensed vehicle operating conditions, and controls the shift control solenoids such that the automatic transmission shifts into only a first speed stage in the drive mode when the transmission control unit detects the change in the driving mode from the reverse mode to the drive mode.

A connecting structure of a lead wire is electrically connected to an electrode in which a polarized electrode layer is formed on a surface of a current collector plate. A region of the electrode, to which the lead wire is to be joined, is free from the polarized electrode layer. The lead wire is joined to the current collector plate by means of stitching and then compressed thereto. This connecting structure may keep a capacitance of a capacitor and improve contact reliability. An electric double layer capacitor having the structure and a method for manufacturing the capacitor are also provided.

A centrifuge includes a rotator comprising a receiving unit receiving materials and guiding the materials to move upward by centrifugal force to an upper portion of the receiving unit, and a rotator cover covering the upper portion of the receiving unit. The centrifuge also includes a container that is coupled to the rotator cover to be connected to the receiving unit and that receives the materials moved upward along the receiving unit. The centrifuge and a centrifuging method as disclosed herein are used for separating a fluid to which a large centrifugal force is applied and a fluid to which a smaller centrifugal force is applied by adjusting the rotation speed using the principle that centrifugal force during rotation varies according to specific components of a fluid. Thus, using the centrifuge and the centrifugal method, materials can be centrifuged and layers of the materials can be classified and collected accurately and easily.

Disclosed is a skin cooling device which utilizes the sensory ability of the skin as an integumentary sense organ so that it is applicable to medical treatments and surgical operations, while being configured to use the heat absorbing effect of a thermoelectric element while having a small size to be easily handled. The skin cooling device includes a case having a size allowing the user to grasp the case by the hand, and a thermoelectric element installed in the case. The thermoelectric element has a heat emitting portion and a heat absorbing portion. The skin cooling device also includes a heat sink unit provided at the heat emitting portion of the thermoelectric element, and cold heat transfer unit provided at the heat absorbing portion of the thermoelectric element, and adapted to locally transfer cold heat from the thermoelectric element to the skin. Thus, the cold heat can be locally applied to the skin.

A novel type of method for mandibular angle fracture operation requiring only incision of lateral of mandible and its devices are provided. Only 20 mm of the incision of mandible makes it possible for an operator to perform the operation and to save time and recover time without incision of patient's face because the operator uses the patient's mouth to broaden the operator's view. A mandibular retractor comprising a handle, a frame, an activated shaft having a tip and a controller lever is provided for cutting or holding the target area of the mandibular. A drill-driver comprising a handle, a neck, a power transferring member, a head including a tip hole and an operation axis and a power connection member provided for fix a metal plate on the bone. A tweezers comprising a body portion, a pair of leg portions which are twisted by 90 degree about the body portion and paralleled each other is provide for holding a bolt or nut.
