A scan chain group structure in which a group of scan chains formed for each clock tree system in an LSI is subjected to a reconnection process so that the scan chain group is not present across a plurality of clock distribution regions obtained by dividing the clock-supplied region of the clock tree of one system and that the connection distance thereof in the distribution region becomes short, a test clock input mechanism in which test clocks to be input to the distribution regions are independent sub-clock phases, and an on / off mechanism of the clocks to be input to the distribution regions are realized. Further, the scan-in / out and scan test performed at the same time are limited in one region or between single regions, and tests in all regions and between all regions are carried out by a plurality of times of test steps.

The invention relates to a device for lubricating the cylinders of a roll stand, in particular for roll nip lubrication in a roll stand for strip-shaped rolling stock. A mixture made out of water and oil is produced by means of a mixing and spraying device (1). Said mixture is sprayed onto at least one of the cylinders (2) of the roll stand and / or to the surface of the rolling stock (3). The mixer and the spraying device (1) consists of an arrangement consisting of several nozzle mixer units (4), water being guided thereto by means of a first supply line (5) and oil being guided thereto by means of a second supply line (6).

The purpose of the present invention is to provide an engine device in which an engine (3) and an exhaust gas purification device (47) can be placed in a compact manner inside a machine housing (2) of a stationary power-generating work machine (70), for example, while allowing the maintainability on the upper surface side of the engine (3) to be improved. This engine device comprises: a first case (48) that removes particulate matter in an exhaust gas of an engine (3); and a second case (49) that removes nitrogen oxides in the exhaust gas of the engine (3). The second case (49) is connected to the first case (48) via a urea mixing pipe (59). The engine device comprises a support mount (65) for firmly fixing the first case (48), the second case (49), and the urea mixing pipe (59) in a parallel manner. The first case (48), the second case (49), and the urea mixing pipe (59) are arranged integrally on the support mount (65), to form an exhaust gas purification device (47) having a single-component structure, and the exhaust gas purification device (47) is attached to a support leg (66) provided to the engine (3).

Provided are a television main board PCB and a TDMA noise inhibition method thereof. The television main board PCB comprises an operation amplifier IC and a filtering capacitor. The operation amplifier IC is arranged on the top layer of the television main board PCB and comprises power supply input ends and power supply ground ends. The filtering capacitor and the operation amplifier IC are arranged in a back-to-back manner. The filtering capacitor is arranged on the bottom layer of the television main board PCB. The power supply ground ends of the operation amplifier IC are firstly electrically connected with one pole of the filtering capacitor, and then electrically connected with the main board ground of the television main board PCB though one pole of the filtering capacitor. The power supply input ends of the operation amplifier IC are electrically connected with the other pole of the filtering capacitor. The peripheral areas of the wires electrically connected between the power supply ground ends of the operation amplifier IC and one pole of the filtering capacitor are not covered by copper layers. According to the invention, the connection distance between the operation amplifier IC and the filtering capacitor of the television main board PCB is the shortest, the power supply ground ends of the operation amplifier IC and one pole of the filtering capacitor are connected with the main board ground of the television main board PCB together, a single-point loop mode is formed since the wired areas between the power supply ground ends of the operation amplifier IC and one pole of the filtering capacitor are not covered by the copper layers, and audio and video signals containing TDMA noises are directly sent to the filtering capacitor to be effectively filtered.
