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 hologram screen is produced by using a transmission-type hologram film, permitting images to be seen from the side of the projector. The hologram screen has a transparent member and a hologram film stuck to the transparent member, and produces the image by projecting image-forming light from the projector. The hologram film is of the transmission-type. The hologram screen also has a reflector for reflecting the image-forming light arranged on the back surface side of the hologram film.

A wire for a wire saw apparatus for slicing a material includes an element wire, a binder coated on an outside circumferential surface of the element wire, and abrasive grains dispersed in the binder. The element wire is a high tensile strength metal wire, the binder is a material such as an organic or inorganic material other than a metal, and the abrasive grains are held on a surface of the element wire by the binder. The element wire is also made by either a natural quartz glass or a high purity synthesis quartz glass.

There are provided a solidifying material used for radioactive waste which comprises a latent hydraulic material, an ultra-fine powder substance and a dispersing agent, and a process for the solidification of radioactive wastes which comprises kneading the above solidifying material with a cure stimulating agent, radioactive waste and, as occasion demands, water, and then curing the mixture by aging. Since the solidifying material of the present invention has excellent properties such as large treating capacity, excellent water resistance and large compressive strength, not only temporary storage but also permanent storage of radioactive wastes can be made.

A flow control device comprising a spindle having a disk at its lower end and a handle at its upper end and spring-biased to bring the disk into pressing contact with a disk seat within a case, a closure having a top wall, and at least one rollable member resting on the upper surface of the closure top wall and mounted on the spindle at an upper end portion thereof projecting upward from the upper surface of the closure top wall. The closure is formed in the upper surface of its top wall with a lower recessed portion for the rollable member to partly fit in, an upper recessed portion for the rollable member to partly fit in and a slanting guide face between the two recessed portions. The rollable member is movable by the rotation of the handle to partly fit into the lower recessed portion to thereby hold the disk in pressing contact with the disk seat or to partly fit into the upper recessed portion to thereby hold the disk away from the disk seat.

A method of treating radioactive waste water generated during chemical decontamination at nuclear power facilities is disclosed. Decontaminating agents, with organic acids, and normally containing inhibitors and surface active agents, are decomposed by oxidation using hydrogen peroxide, at a temperature of 60.degree.-90.degree. C., in the presence of copper ions, or copper ions and iron ions, as catalysts.

A developing device includes a developer bearer, a developer regulator disposed opposite the developer bearer across a first gap, and an opposing member having an opposing face disposed opposing the developer bearer across a second gap wider than the first gap. The opposing face is disposed adjacent to and upstream from the developer regulator in a direction of rotation of the developer bearer. The opposing face is inclined relative to an orthogonal plane direction orthogonal to a side face of the developer regulator. The opposing face is inclined to progressively reduce a distance from the developer bearer to the opposing face in a direction of rotation of the developer bearer. A difference between the second gap and the first gap is not greater than 1.75 times as large as the first gap.

Gas flow rate measuring apparatus comprising resistive element disposed in a gas flow path, a gas flow rate detection circuit, and a gas temperature detection element or a substrate temperature detection element. The detection circuit detects a current flowing through the resistive element, or a voltage generated in response to the current to output a gas flow rate detection signal in accordance with a flow rate of gas flowing. The apparatus corrects characteristics of the gas flow rate detection signal on the basis of a temperature detection signal obtained from these elements and includes signal conversion means for correcting a characteristic bend displaced by more than a certain fixed amount from target characteristics.

[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.
