Abstract:
An on-screen display (OSD) vertical blanking signal selection circuit for a display apparatus comprises: a microcomputer for generating a reference oscillating signal in response to vertical and horizontal synchronous signals from a video card; an HV processor for generating a flyback transformer (FBT) drive signal and horizontal and vertical drive signals in response to the reference oscillating signal from the microcomputer and the horizontal and vertical synchronous signals from the video card; an FBT for generating a high voltage in response to the FBT drive signal from the HV processor and for supplying the generated high voltage to a cathode ray tube; a horizontal deflection circuit for controlling horizontal deflection of electron beams in a cathode ray tube in response to the horizontal drive signal from the HV processor; a vertical deflection circuit for controlling a vertical deflection of the electron beams in the cathode ray tube in response to the vertical drive signal from the HV processor; and an OSD vertical blanking signal selector for supplying the vertical synchronous signal from the video card or a vertical blanking signal from the vertical deflection circuit as an OSD vertical blanking signal to an OSD circuit in response to a control signal from the microcomputer.
Abstract:
The present invention provides a multi-wefts inserting weaving machine, comprising a block arraying device comprising an upper plate and a lower plate which face each other and are movable upward and downward; and a plural number of unit blocks attached to the internal facing sides of the upper plate and the lower plate of the block arraying device through combining grooves, wherein the unit blocks include two grooves. Accordingly, a lattice woven structure can be easily woven from heavy-duty materials by the present multi-wefts inserting weaving machine.
Abstract:
The present invention relates to a press-dewatering rubber tub for a continuous washing machine, which is mounted on a dewatering part positioned on the rear end side of the continuous washing machine configured by a plurality of washing compartments and is configured to be movable upward or downward by a driving cylinder so as to press a laundry in a dewatering tank, wherein a plurality of high-elastic honeycomb fillers as a filler for reinforcing durability have a hollow shaped therein and are stored in the dewatering rubber tub in a state that releasing of the honeycomb fillers is prevented by an outflow prevention cover. Therefore, the high-elastic fillers are used in the dewatering rubber tub, thereby reducing the weight of the dewatering rubber tub. Moreover, there is an effect that an amount of consumed power required for driving a driving cylinder can be reduced.
Abstract:
A fuel cell system includes a fuel cell stack generating electric power using an electrochemical reaction between hydrogen and oxygen, a fuel process unit supplying reformed gas to the fuel cell stack by reforming an electricity generation material into the reformed gas that is rich in hydrogen, and an air supply unit supplying air containing oxygen to the fuel cell stack. The air supply unit includes an intake passage that extends from an outside space to the fuel cell stack, a first air pump that is installed on the intake passage to allow the air to be introduced into the fuel cell stack, and a first pressure buffer container that is disposed between the first air pump and the fuel cell stack to reduce pressure of the air flowing along the intake passage to a level less than a predetermined pressure.
