Abstract: A hydraulic control device for an auto transmission may include: an oil pump unit configured to supply oil; a line pressure control unit configured to form line pressure using the oil supplied from the oil pump unit; a lubricating pressure control unit configured to form lubricating pressure using the oil passing through the line pressure control unit; a reducing pressure control unit configured to form reducing pressure using the oil passing through the lubricating pressure control unit; a damper control pressure control unit configured to form damper control pressure using the oil supplied from the oil pump unit; a switch unit configured to supply the lubricating pressure or the reducing pressure to a torque converter; a collection unit configured to collect the lubricating pressure; and a retention unit connected to the switch unit, and configured to retain the lubricating pressure of the torque converter.

Abstract: Provided are a dope solution for preparing a polarizing plate protective film by a solution casting method using an acrylic polymer with high thermal resistance and high molecular weight, and a polarizing plate protective film using the same. The polarizing plate protective film using the dope solution according to the present invention has excellent optical properties, high tensile strength, low hygroscopic properties, and high thermal resistance, and thus, has the effects of excellent dimensional stability, and excellent adhesion with a polyvinyl alcohol film.

Abstract: Disclosed is a main unit and at least one expansion unit having a housing that contains a jack extending from the top of the housing and a plug extending from the bottom of the housing, the jack of one module mating with the jack of another module. Each module, including the main unit, each contain at least one circuit panel between the jack and the plug. A rigid, non-flexible connector electrically connects the jack and the plug of each unit to the circuit panel. In addition, the top side of each panel contains a flange around the periphery of the top side that mates with a recess that runs around the periphery of the bottom side of an adjoining module to attach the two modules together.

Abstract: A portable, lap-top constructed with a body that encases the computer and a keyboard, and a display housing that encases a variable visual display driven by the computer. A hinge assemble rotatably connects the body with the housing for the display. The hinge assembly includes a horizontal bracket, a hinge member formed on the horizontal bracket, a pivot-bracket assembly, including a pivot and a bracket, rotatably connected to one side of the hinge member, perforated by a plurality of holes that allow the assembly to be attached to the body housing the computer. The hinge assembly is electrically joined with a mother board of the computer by a bolt inserted through holes formed in a bottom case of the body and the mother board.

Abstract: A protecting device for an electronic peripheral device, the protecting device having a front cover, mounted on a front surface of the housing for the electronic peripheral device and a door which is opened or closed depending on whether the peripheral equipment needs to be used. The door is pivotally connected to both sides of the front cover such that it protects the peripheral equipment from being damaged. A controlling device is are provided for controlling the opening speed and opening degree of the door.

Abstract: A computer case including two pairs of apertures, a first pair accommodating the push buttons and a second pair accommodating and engaging a pair of locking hooks. The hooks are biased closed by a torsion spring. The hooks and the push buttons are formed integrally on a single monolithic fastening latch which pivots about a support shaft. A support bar is placed behind the push buttons to prevent the push buttons from being pushed in too far preventing the springs from being compressed too much.
