Abstract: An image forming apparatus includes a print job addition notification reception controller that receives from outside a print job addition notification that indicates a print job is added to a server, a print job reception controller that acquires the print job from the server, a print controller that performs printing based on the print job acquired from the server, and a service state controller that sets a service state to be any one of a service enabled state, in which the print job addition notification is received and the print job is acquired from the server, and a service stopped state, in which the print job addition notification is not received and the print job is acquired from the server based on an operation of a user.

Abstract: Provided is an electrode (1) which has a double structure including Cu or a Cu alloy as an electrode body (2) and a core material (3) made of W, Mo, a W-based alloy, or a Mo-based alloy embedded in a surface of the electrode body (2) which is abutted against a material to be welded, the core material (3) being formed by using W, Mo, the W-based alloy, or the Mo-based alloy which is in the form of a fibrous structure extended by sintering, swaging, and annealing in an electrode axis direction, the fibrous structure having a horizontal cross-sectional average particle diameter of 50 ?m or more and an aspect ratio of 1.5 or more. The electrode (1) can be used as an inexpensive electrode obtained by suppressing particle dropping/attrition and defects in electrodes for spot welding, in which heat and pressure are applied repeatedly, stably enhancing durability.

Abstract: A voice mail device includes a packet storing section which stores a received audio packet including audio data in a first encoding format. Therefore, the received audio packet is stored as it is without undergoing any transcoding, so that it is possible to reduce a need for transcoding upon receipt of the audio packet, and as a result, reduce a need for an audio CODEC.

Abstract: The router unit is built in the main key telephone apparatus, the office line interface function and the independent power supplying function are deleted in the router unit, and the office line interface units and the power supply unit substitute for these functions.

Abstract: The present invention relates to a method for the treatment of sludges such as sewage sludges, night soils, water supply sludges, sludged deposition in bottoms of rivers, lakes, harbors and seas and industrial waste water sludges. According to this method, a fiber in an amount of 0.05 to 20% by weight based on solids in a sludge to be treated and an inorganic coagulant or polymeric coagulant are added to the sludge to coagulate the sludge, and water is removed from the coagulated sludge to obtain a filter cake having a low water content.

Abstract: When a bituminous emulsion is added to a water-containing sludge, the sludge is instantaneously separated into an aqueous layer and a solid layer. But, heavy metals other poisonous pollutants cannot be removed from the separated aqueous layer. In contrast, when a sulfur compound or colloidal sulfur is added to such sludge in combination with a bituminous emulsion, heavy metals and other poisonous pollutants are converted to water-insoluble or hardly soluble sulfur compounds and they are readily removed from the separated water layer. When an inorganic coagulant or organic polymeric coagulant is added in combination, the coagulating and solidifying effects can be further increased. Moreover, the heavy metals and other pollutants fixed in the solid layer are hardly dissolved out and therefore, the separated solid cakes can be used for reclaiming or as water shielding walls.
