Disclosed is a method and apparatus for picture compression using a variable block of an arbitrary size, the method comprising: a first step of calculating motion vectors of desired variable blocks; a second step of dividing a screen into a plurality of blocks of arbitrary sizes according to the calculated motion vectors of the variable blocks; and a third step of determining motion vectors with respect to each of the plurality of blocks of the arbitrary sizes constructing the divided screen. Also, the method comprises a first step of compensating motion with respect to blocks of arbitrary sizes from which the motion vectors are decided; and a second step of transmitting block information of an arbitrary size for which the motion is compensated, in order, from a block disposed on the upper left of the screen to a block disposed on the lower right of the screen.

The invention relates to a pyrophosphoric acid bath for use in cyanogen-free copper-tin alloy plating that contains an additive (A) composed an amine derivative, an epihalohydrin and a glycidyl ether compound with ratios of epihalohydrin to glycidyl ether compound being 0.5–2 to 0.1–5 on mol basis, per 1 mol of the amine derivative, has a pH of 3 to 9, and optionally contains an additive (B) composed of an organic sulfonic acid and / or an organic sulfonic acid salt, and to a copper-tin alloy coating obtainable by using the bath. The invention provides a pyrophosphoric acid bath for use in copper-tin alloy plating of the cyanogen-free type utilizable on an industrial scale, particularly, capable of performing uniform treatment to exhibit low defective product generation rates even with the current density being incessantly changing between a high state and a low state, as a barrel plating method, and a copper-tin alloy coating obtainable by using the bath.

The present invention relates to the multifunctional urgent shutoff safety valve for preventing accidents such as gas explosion, fire, etc. in advance. It is installed at the gas supply path. The spool assembly run by earthquake accelerations in case of an earthquake of stronger than a fixed level shuts off the gas circulation path to stop gas supply, or the spool assembly shuts off the gas circulation path to stop gas supply when an excessive amount of gas is flowed out in a short time due to blowing-out of the rear end pipe of the present valve. In the configuration of the multifunctional urgent shutoff safety valve of the present invention, a permanent magnet, which is mounted on the upper end of the spool assembly installed at the valve room in the main body in the vertical state to pen and close the outlet port, is suspended apart from the bottom surface of the pendulum (acceleration sensor) at a fixed interval, when the valve outlet port is open. If earthquake accelerations of stronger than a fixed level are delivered to the multifunctional urgent shutoff safety valve of the present invention, the pendulum (acceleration sensor) swings or tilts increasing the distance from the spool assembly suspended on the lower surface of the pendulum, the spool assembly is dropped down on the valve seat, and the outlet port is closed thus preventing the flow of gas.

A sealing cover (10) is provided for closing an opening of an equipment case that accommodates electric equipment of a car. The electric equipment includes a circuit with an operation control portion for switching a main circuit from an operating state to a shutdown state in accordance with signals inputted to an input terminal thereof. The sealing cover (10) has a cover body (11) mounted on the equipment case to close the open part. An interlocking connector (35) is provided on the cover body (11) and is connected to the input terminal when the cover body (11) is mounted on the equipment case and disconnected from the input terminal when the cover body (11) is removed from the equipment case to switch the main body circuit from the operating state to the shutdown state.

Provided are a semiconductor device including a fuse focus detector, a fabrication method thereof and a laser repair method. In a chip region, fuses may be formed at a first level. A fuse focus detector including first and second conductive layers may be formed in a scribe line region. The first conductive layer may be formed at the first level, while the second conductive layer may be formed at a different level. For a laser repair method, a target region may be divided into sub-regions. In one selected sub-region, the fuse focus detector may be laser scanned in a direction for a reflection light measurement providing information on a thickness of the fuse focus detector. Using the thickness information, a focus offset value of a fuse in the selected sub-region may be calculated. When the focus offset value is within an allowable range, fuse cutting may be performed.

A combination of chemical agents reduces reductive stress by limiting the accumulation of high-energy electrons potentially available to the electron transport chain. A method of metabolic uncoupling therapy comprises: analyzing a specific physiologic process involving reductive stress; identifying a plurality of MUT agents that modulate metabolic pathways by influencing electron flux; and formulating a combination of MUT agents that limits the accumulation of high-energy electrons potentially available to the electron transport chain.
