Abstract: A water-in-oil emulsion explosive characterized by containing an ethylene vinyl acetate copolymer. It has excellent long-term stability. Even when stored under a load for as long as about one year, the explosive is less apt to suffer a decrease in explosive performance and coagulates only slightly in such a degree that it comes to have weakly coherent partial coagulates which can be easily disaggregated. Even after long-term storage, charging with the explosive can be easily conducted with a charger. Since the explosive has excellent water resistance, it is suitable also for blasting in a water hole.

Abstract: An industrial vehicle includes a transmission, which is coupled to an engine by a torque converter. When the vehicle is accelerating, the rotational acceleration of driving wheels is computed based on the rotational speed of the driving wheels. A traction control procedure is executed based on the rotational acceleration for eliminating spinning of the driving wheels. When the vehicle is decelerating, the rotational deceleration of the driving wheels is computed based on the rotational speed of the driving wheels. An anti-lock brake control procedure is executed based on the rotational deceleration for preventing the driving wheels from locking. As a result, skidding of the driving wheels is reliably prevented by a simple structure.

As a result, co-located mode of a mobile node (MN) is used, and VPN information according to a security level of a network that accommodates the mobile node is distributed in a location registration procedure of a mobile IP, so that a VPN that effectively uses a tunnel set-up process of the mobile IP is configured.

Abstract: The present invention relates to an IP network including mobile environment and, in particular, to a service control network and its control method for providing individual service every user or terminal of an IP network. In a service control network including a service control device for performing Layer-7 service control for mobile terminals, an authentication server device specifies a Layer-7 profile and an associated dependent Layer-3 profile of a mobile terminal at the success of the authentication of the mobile terminal. An edge device transfers packets, which have been received from the mobile terminal after the success of the authentication of the mobile terminal and match the dependent Layer-3 profile, to the service control device. The service control device controls the implementation of a Layer-7 service for packets which have been received from the edge device and match the Layer-7 profile.

Abstract: A billing system is disclosed which performs processing in order to provide service to user terminals, and which performs billing for the service provided to the user terminals. In this billing system, user billing profiles UBP are stored in a user billing profile registration unit, by service type and in user terminal units; a billing condition generation unit within a service provider server compares the user billing profile UBP corresponding to a specified service type and to a user terminal with a server billing profile SBP to generate billing conditions, and a billing condition setting unit of a foreign agent sets the billing conditions in a billing unit; and based on the billing conditions thus set, the billing unit executes billing processing for each user terminal.

Abstract: A photovoltaic element which directly converts an optical energy such as solar light into an electric energy. After many uneven sections are formed on the surface of an n-type crystalline silicon substrate (1), the surface of the substrate (1) is isotropically etched. Then the bottoms (b) of the recessed sections are rounded and a p-type amorphous silicon layer (3) is formed on the surface of the substrate (1) through an intrinsic amorphous silicon layer (2). The shape of the surface of the substrate (1) after isotropic etching is such that the bottoms of the recessed sections are slightly rounded and therefore the amorphous silicon layer can be deposited in a uniform thickness.

Abstract: An ampule separator which can efficiently cut off ampules from a strip of series-connected plastic ampules. A strip of series-connected plastic ampule is put in a stocker having an outlet at its bottom, with the individual ampules arranged horizontally. A pair of horizontally arranged rotors are provided under the outlet of the stocker. Each rotor is formed, in its outer peripheral surface, with a groove in which the body of a plastic ampule can be partially received. As the rotors are rotated, the lowermost one of the plastic ampules is received in the grooves. As the rotors are rotated further, the ampule in the grooves is pushed down and cut off along a cutoff line formed between this and the immediately upper ampules by the rear edges of the grooves, with the upper ampules supported on cylindrical outer surfaces of the rotors.

Abstract: An exhaust gas purifier includes a filter for collecting particulates, a heater for firing collected particulates, a blower for feeding air, and a controller for controlling power supplied to the heater and air flow rate of the blower. The air flow rate is varied in a regeneration period for improving the regeneration efficiency and for protecting the filter. In one embodiment, the air flow rate is initially reduced in the burning period and increased after burning in the radial direction at the downstream portion of the filter. The burning propagation speed, the heat generation and the increase of the temperature of the filter are limited by suppressing the air flow rate in the burning period. The particulates remaining in the downstream portion of the filter due to the suppressed air flow rate supplied in the burning period can be burned subsequently by supplying an increased air flow rate after the burning period.
