Title: Flowing refuse obstruction prevention measure in flowing-in power plant
Inventor: ENDO KAZUO
IPC: E02B7/20
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To flow out refuse and the like along a refuse flow plate by arranging the refuse flow plate before a screen, attaching a closing type refuse flowing-in prevention flow to make a sand discharge gate two stages and flowing out refuse and the like in the opening of an upper stage gate. SOLUTION: An interval between a refuse flow plate 1 and a screen is opened to enable refuse removal of the screen, and refuse and the like are flowed in from the upper part between the refuse flow plate 1 and the screen to be adhered to the screen. In this case, a refuse inflow prevention cover 4 is mounted to prevent refuse and the like from flowing in. Drifting wood and refuse float around an intake only in mounting the refuse flow plate 1, and flow in from the lower part of the refuse flow plate 1 to be adhered to the screen. A sand discharge gate 2 is made two stages to open only an upper stage gate 3 and intake is performed while refuse and the like are flowed out. Thereby flowing refuse obstruction is eliminated to enable power generation, and further drifting wood and refuse can be flowed out while power generation output is secured.

Dehumidification is performed by the endothermic actuation. The temp. in the dehumidification tank of the easing 2 of the dehumidifier 1 is made higher than the temp. in an installation chamber provided with the dehumidifier by the exothermic actuation. As a result, the pressure in the dehumidification tank is made higher than the pressure of the outside thereof. The high-humidity air of the outside is made difficult to be introduced into the dehumidification tank. Thereby the humidity in the dehumidification tank is made difficult to be raised. The storage material stored in the dehumidification tank is protected from moisture.

Title: Resin-sealed semiconductor device
Inventor: SHIMOMURA KO
IPC: H01L23/29
Filed: 1990-12-20
Abstract: PURPOSE:To prevent a metal thin film from flowing, from being deformed or from being revealed to the surface of the title device and to prevent the trouble such as the deformation or the like of an island and a lead frame from being caused by a method wherein a sealing resin whose lowest melting viscosity at its molding operation inside a metal mold is specific is used. CONSTITUTION:The title device is molded by using a sealing resin whose lowest melting viscosity at its molding temperature is at 300 poise or lower. For example, a sealing resin in which an epoxy resin, a phenol resin and silica have been mixed is adjusted in such a way that its lowest melting viscosity at its molding operation using a metal mold is at 220 poise. As compared with conventional cases, the spherical ratio of silica as a filler is increased as measures to lower its viscosity, and measures to make its viscosity distribution wide are taken. For example, as compared with a case where the resin at 370 poise is used, the defect ratio of a resin-sealed semiconductor device due to a metal thin wire 3 revealed to its surface is remarkably small.
