A fire alarm system which makes fire determination based on a novel idea which considers various changes of the physical phenomena in the surroundings caused in relation with the occurrence of a fire in terms of changes of vectors. These changes in the physical phenomena are detected by the detecting section in the form of analog data and processed by a data sampling section as sampled data and st...

An X-ray examination apparatus for examination of composite objects, such as, for example, peripheral examination of patients, comprises, in order to avoid over-radiation of the detection system by radiation passing along the object, a filter that can be adapted to the interstices. Such a filter consists, for example, of a body of radiation-absorbing material having in two directions a varying rad...

The invention concerns a centrifuge intended for use in mainpulating liquid batches on an analytical scale. The centrifuge consists of a body (2) rotatable about its axis (1) provided with input and output conduits (8,9,11) and presenting the essential feature that therein are contained two parallel, circular arc-shaped volumes (3,4) located at different distances from the axis (1) of the body (2)...

A reduction process and apparatus wherein the flow of the reducing fluid through the fixed bed of iron ore, oxidized pellet or the like to be reduced is reversed in direction so that the iron ore, oxidized pellet or the like, at any place in the bed, may be reduced uniformly.

PURPOSE:The tube for introducing the compound of an element of group V into the reaction tube is made to pass through inside the heating means which is set inside the reaction tube to promote the thermal decomposition of the hydride of the V-group element and improve the reaction efficiency in the vapor-phase growth of the III-V group compound semiconductor. CONSTITUTION:At first, valves 30, 40 ar...

The invention relates to instruments of the anti-resonant acoustic enclosure type making it possible to damp the sound pressure of the rear wave of the loudspeaker through better rigidity of the walls and promoting the sound aspect by its shape. It comprises a hub 1 receiving the tie bars 3, the latter being connected to pentagons 5 at their centre by way of silent blocks 4. External screws exert ...

PURPOSE:To enable the detection of deficiency due to short-circuiting in a lead storage battery by detecting current flowing to a separator owing to humidity and that flowing during the short-circuiting. CONSTITUTION:Connection terminals 4 and 5 of a short-circuiting inspector are brought into contact with a positive electrode 6 and a negative electrode 7 of a battery and a desired high voltage is...

A plurality of adsorption containers are provided which are separated into heater adsorber zones and condenser evaporator zones. The zones are successfully rotated through flow segments which form a passageway for heat carrier flows. The heater adsorption zones contain an adsorption substance from which an operating substance is extracted by adsorbing heat from a heat carrier flow and is again ads...

PURPOSE:To classify and to recover waste dry cells easily with high efficiency by performing the first classification by the shape and size, then performing the second classification by the specific gravity using heavy liquid or quasi-heavy liquid for waste dry cells classified by the first classification to the same shape. CONSTITUTION:Waste dry cells are classified in the first stage mechanicall...

PURPOSE:To obtain a neutron absorber made of amorphous alloy in which a neutron absorbing element does not transfer durig use and disperses uniformly by adding the neutron absorbing element to Fe and/or Ni. CONSTITUTION:Fe or Ni is used as a primary component, or Fe is mixed with Ni to prepare an amorphous alloy. The alloy is formed into a uniform ribbon shape having about 100mm. width and about 2...
