摘要:
The present invention comprises a sealed type container body (50) capable of storing molten metal; a flow passage (57) capable of flowing the molten metal, the passage is formed extended to an outside of the container, and the passage is formed towards an upper portion (57b) from an opening (57a) provided at a position on an inner and near a bottom portion (50a) of the container body (50); and means (101, 0313) for controlling the pressure in the container body. This makes it possible to provide a container or the like requiring no replacement of parts such as a stoke and the like.

A molten metal supplying container, comprising a container capable of storing a molten metal and loading the molten metal to the inside thereof or supplying the molten metal to the outside thereof by controlling a difference in pressure between inside and outside of the container, a passage allowing the inside and outside of the container to communicate with each other to have the molten metal flow therethrough, a lid disposed to cover the first opening having a second opening with a diameter smaller than the first opening and a hatch provided at the second opening capable of being opened and closed, having a passage communicating inside and outside the container. The passage is used, for example, to control inner pressure of the container and to insert the electrode for detecting the surface level of the molten metal.

When emergency shutdown operation becomes necessary while a gas used for applying pressure to the in of the container is being supplied from the receiver tank to the container, the lever is turned and the three-way valve is switched to the second mode. Then the first valve opening in the three-way valve is blocked and the supply of the gas used for applying pressure to an inside of the container from the receiver tank to the container is stopped. In addition, since the gas can flow between the second valve opening on the container side and the third valve opening opened to an atmosphere in the container is released to an atmosphere. In other words, in the present invention, the supply of the gas used for applying pressure to the in the container can be stopped and, in the same time, in the container is released to the atmosphere with a single action, namely, manually turning the lever provided close to the driving seat. Therefore, the safety level of the system is very high.

A pressure controlling apparatus controls a pressure in a container capable of storing a molten metal and supplying the molten metal to an outside using a pressure difference and includes: a supplying portion for supplying a compressed gas to be supplied to the container; a flow passage for supplying the compressed gas from the supplying portion to the container; a first switching valve, being inserted into the passage, capable of manually switching a first mode that enables the passage of the gas between the supplying portion side and the container side and a second mode that enables the passage of the gas between the container side and the outside; an exhausting portion for exhausting a gas from the container; and a second switching valve for switching a pressure applying mode for applying a pressure to the container and an exhausting mode for exhausting the gas from the container.

[OBJECT] To efficiently and assuredly making an object to be treated containing an agricultural chemical innoxious.[MEANS FOR SOLVING] The first pipe which alkali can be filled thereto is disposed to be capable of being inserted and pulled out to a first passage of the first processing chamber where agricultural chemicals are thermally decomposed. Accordingly, since a distance between the processing chamber and the alkali can be minimized, a zone where the thermally decomposed components of the agricultural chemicals are recomposed into agricultural chemicals or dioxins is almost eliminated. As a result, the contamination owing to the re-composition thereof can be prevented. In addition, since the first pipe can be readily exchanged, the throughput can be improved. Furthermore, since when the first pipe is pulled out of the first passage of the processing chamber a first shielding member can shield the first passage, the vacuum in the processing chamber can be maintained and also in this point the throughput can be prevented from deteriorating.

A 1.55 μm band dispersion shifted optical fiber is provided which has a low loss and low dispersion slope. A core region “a” is heavily doped with GeO2 . A core region “b” is composed of pure SiO2 glass. A cladding section is arranged around the core region. The cladding section has a lot of holes extending in the longitudinal direction of the optical fiber. The holes of the cladding section are not located at random, but have a honeycomb structure composed of regular hexagons which have a side length of Λ, and serve as a primitive lattice. The center of the core section has a region having a refractive index higher than that of the periphery of the core section. The core section has the refractive index distribution in which the group velocity dispersion at the operation wavelength of the region becomes the normal dispersion.

The present invention provides an active control type noise reducing device that is disposed at a sound barrier and with which can be obtained an excellent noise reduction effect with respect to moving sound sources. Linear array of flat loudspeakers are arranged in ascending order from an incoming side of automobiles towards an outgoing side. Delay times of 0, τ, 2τ, . . . , 8τ are respectively given in the arrangement order to the linear array of flat loudspeakers. By delaying signals in correspondence to the arrangement order, the wavefront of a control sound can be slanted in a diagonal direction. Namely, “line sound sources”, where sound sources are linearly arranged, arc pseudo-realized.

A DPF and a SCR catalyst are provided in an exhaust pipe, and a urea solution addition valve is provided between the DPF and the SCR catalyst for performing addition supply of urea solution into the exhaust pipe. In a urea solution supply system, the urea solution of prescribed concentration is stored in a urea solution tank, and a urea solution pump is provided in the tank. A urea solution supply pipe is connected to the urea solution pump. A part of the urea solution supply pipe is structured as a compound pipe structure defining two passages. One of the two passages serves as a urea solution passage, and the other one serves as an engine coolant passage.
