Abstract:
An information processing system is provided, which allows an information processing device to use network devices across firewall devices without having the firewall devices configured for respective protocols which are to be used for communication with the network devices. By connecting a local machine and a remote machine with each other via a VPN and providing the remote machine with a VPN gateway function, the local machine is allowed to belong to a network on the remote machine side. As a result, in a case where the firewall devices exist between the local machine and the remote machine, merely by setting the firewall devices to connect the local machine and the remote machine with each other via the VPN, the local machine can communicate with the various network devices connected to the network on the remote machine side by means of various protocols.
Abstract:
A fluorescent display tube is disclosed. In the fluorescent display tube, linear members, such as, for example, wire grids and filament are sustained in a predetermined height, while both ends of each linear member are welded on a metal layer by ultrasonic. The fluorescent display tube includes a metal spacer for fixing the linear member and holding the linear members in an elevated position so that the dead space within the fluorescent display is reduced. The linear members are bonded on an aluminum thin films formed on the glass substrate 111 by way of the aluminum spacer. The aluminum spacer sustains the linear members in a predetermined height. Aluminum spacer acts as a member for fixing the linear member and as a height level holding member.
Abstract:
The present invention relates to a Cu—Sn—O alloy plating having an oxygen content of 0.3 to 50 at %, a copper content of 20 to 80 at %, and a tin content of 10 to 70 at % in the plating. The present invention provides a copper tin alloy plating that has excellent plating adhesion and disengaging force stability and particularly a Cu—Sn—O alloy plating that has a blackish color tone without containing any controlled substances.
Abstract:
The invention relates to a pyrophosphoric acid bath for use in cyanogen-free copper-tin alloy plating that contains an additive (A) composed an amine derivative, an epihalohydrin and a glycidyl ether compound with ratios of epihalohydrin to glycidyl ether compound being 0.5–2 to 0.1–5 on mol basis, per 1 mol of the amine derivative, has a pH of 3 to 9, and optionally contains an additive (B) composed of an organic sulfonic acid and/or an organic sulfonic acid salt, and to a copper-tin alloy coating obtainable by using the bath. The invention provides a pyrophosphoric acid bath for use in copper-tin alloy plating of the cyanogen-free type utilizable on an industrial scale, particularly, capable of performing uniform treatment to exhibit low defective product generation rates even with the current density being incessantly changing between a high state and a low state, as a barrel plating method, and a copper-tin alloy coating obtainable by using the bath.
Abstract:
A fluorescent luminous tube is provided that has a getter mirror film formed in an arbitrary shape by illuminating a laser beam onto a getter. In order to form the getter film 32, the rectangular ring-less getter 31 mounted on the anode substrate 11 is irradiated with the laser beam L from the outside of the front substrate 12 and thus is evaporated. In this process, when the illumination spot of the laser beam L is moved along the scanning line 33, the rectangular getter mirror film 32 is formed around the scanning line 33. The burnt region 34, which has the same shape and size as those of the scanning line 33, is formed using the laser beam L.

Abstract:
A low-cost vehicle air-conditioning apparatus for idle stopping vehicles is capable of performing both cooling and heating operations throughout the year. The air-conditioning apparatus includes an engine-driven compressor and engine-driven pump for a heating unit. The air-conditioning apparatus includes a motor-driven compressor and pump. A control unit drives the motor such that the motor-driven compressor is operated when there is a need for cooling and the motor-driven pump is operated when there is a need for heating when the engine is stopped. Battery power is conserved through various methods.
Abstract:
A selectively driven compressor for stopping the power generating operation of a motor when an internal combustion engine is operating to make it unnecessary to provide the motor that can withstand high voltage. The system reduces the load on the internal combustion engine. The system includes a pulley driven by a main drive source, an electric motor, which includes an armature and a field system, driven by a power source. The compressor is driven selectively by the pulley or the electric motor. The armature and the field system of the electric motor are independently supported. The pulley is mechanically connected to either of the armature and the field system, and the compressor is mechanically connected to the other.
Abstract:
A simple and slim double-faced vacuum fluorescent display device has no grid, thereby lowing the power consumption and fabrication cost thereof. Anode electrodes on one of the front plate and the back plate function as grids for anode electrodes on the other one of the front plate and the back plate. The light emitted from anode electrodes is not blocked by grids, thereby enhancing light emitting efficiency thereof.
Abstract:
A bottle-shaped can manufacturing method for forming a shoulder portion having a slope and a diametrically small cylindrical neck portion integrally by further working a bottom side of a bottomed cylindrical can which is formed thinner at its trunk wall than at its bottom wall by drawing a metallic sheet having a thickness of 0.1 to 0.4 mm and by executing at least one thinning working of a bending/extending working and an ironing working. This method comprises: a step of preforming a bottom corner portion of the can into a curved shoulder face having an arcuate longitudinal section; a first diametrically small cylindrical portion forming step of drawing the bottom of the can into a diametrically smaller bottomed cylindrical shape than the trunk portion, with the curved shoulder face of the bottom corner portion being unwrinkled; a second diametrically small cylindrical portion forming step of drawing the bottomed cylindrical portion drawn from the can bottom into a diametrically smaller bottomed cylindrical shape, with the bottom corner portion being unwrinkled by the surface of a tool; and a shoulder portion reforming step of pushing and extending the shoulder portion, which is formed by the first diametrically small cylindrical portion forming step and the second diametrically small cylindrical portion forming step into a smooth slope leading to the curved shoulder face on the trunk side, after the diameter of the bottomed cylindrical portion formed by executing the drawing working of the second diametrically small cylindrical portion forming step once or two or more times becomes substantially equal to a diameter of the neck portion.
