System, device and method for providing screened protection to gutters from clogging debris. Protection is provided by using a panel that includes rain siphoning louvered technology. The louvers may be covered by a filter or screen. If the openings of the louvers are closed to a certain degree, a screen may be dispensed with. The panel is sloped such that debris rolls off a surface of the panel. Additionally, the louvered portion may be domed. The panel ends on one side in a locking mechanism that locks to an outer lip of the gutter and on the other side in a corrugated edge that fits under the overhang of the roof such that it need not be inserted under the shingles.

System, device and method for providing screened protection to gutters from clogging debris. Protection is provided by using a panel that includes rain siphoning louvered technology covered by a filter or screen. The rows of louvers are offset to direct water into the vertical openings. The louvered portion is dome shaped to permit the louvers to be vertical and to help debris roll off the sides. The filter is molded to the rows of louvers to conduct water to the vertical openings of the louvers. The filter or screen is secured to the panel by being laid in opposing hems on the two sides of the louvered portion of the panel and then by rolling beads or ribs onto the hemmed portions.

In a process in which a plurality of substrates are successively inspected, the tips of pins are cleaned without interrupting the flow of substrate inspection. A substrate-inspecting device (10, 70) comprises holders (40) for substrates to be inspected provided along the conveying path at predetermined intervals, and a moving means (22t) for moving the holders along the conveying path, an inspecting section (30) that is provided at a position along the conveying path and successively inspects the substrates to be inspected held by the holders of the conveying means, a cleaning means (50) provided between any adjacent holders from among the holders provided along the conveying path at the predetermined intervals. The inspecting section brings the pins into contact with inspection points in wiring on the substrates to be inspected and measures the electric characteristics of the wiring. The cleaning means is moved by the moving means of the conveying means, and cleans the pins when the cleaning means passes through the inspecting section.

The present invention, relating to a water-pollutant separation device, on which a water-pollutant separation and filtration device, an ornamental fish tank water-pollutant separation and filtration system, and a high density cultivation water-pollutant separation, filtration and oxygen aeration system are based on, comprises a tank, a water inlet pipe and a water outlet pipe respectively communicated with the top of the separation tank, and a pollutant discharge pipe disposed at the bottom of the tank; the inner cavity of the tank is provided with a separation structure which is in an inverted barrel shape, having an upper closing cover and slightly smaller external dimensions than that of the tank which provides a gap between the separation structure and the bottom of the tank; a spoiler is installed onto the water inlet pipe after the water inlet pipe passes through the upper closing cover of the separation structure in the tank; the spoiler is sealed at the lower end, and is provided with a plurality of openings or slots on the side wall to generate a subcritical flow to spoil the water flow, the openings or slots being biased in the same direction. In the technical solution, a water-pollutant separation device is preferably added prior to fish tank filtration, and the multiple slots provided on the spoiler are suitable for splitting the flow of relatively large water flow, so that most pollutants in the water can be separated and discharged, thus reducing the accumulation of the pollutants on filtration material, and improving water quality and stability.

An electro-optical module is provided in the form of a Ceramic Ball Grid Array (CBGA) optical package with a detachable fiber optic connector. The electro-optical module is surface mountable on a printed circuit boards (PCB) using standard electronics pick-and-place and reflow manufacturing technology. A module housing array of ultra-high-speed single mode fiber based optical transmit and / or receive devices provides for high density fiber interconnections and can be mounted directly on a PCB in close proximity to associated electronics. The resulting shorter electrical interconnects reduce losses and distortion of the high frequency electrical signals enabling lower power signals and lower error rates on the interfaces, for applications such as high-speed data center interconnects. Shorter electrical interconnects may also allow for simpler clock and data recovery circuits or, in some cases, complete elimination of some of these circuits.
