A remote management system includes a managed device and a management device connected via a network, where events occurring in the managed device are managed via an event system scheme which can be adapted to a number of managed devices. A management module in the managed device detects an event occurring in the managed device and locates one or more enquiry destinations corresponding to the event, in an event enquiry destination table. An enquiry destination is assigned in cases where one or more enquiry destinations corresponding to the event identifier have not been defined in the event enquiry destination table. The management module makes an enquiry by sending an identifier for the event to the management device. Enquiries are made simultaneously or consecutively to the one or more enquiry destinations.

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.

In a method for manufacturing an electron tube including a front substrate and a back substrate, a wiring and an electrode are formed on the front substrate and/or the back substrate. A component is mounted on the front substrate and/or the back substrate. A ring-less getter is mounted on at least one of the front substrate, the back substrate and the component. A vessel is assembled and sealed so that the front substrate faces the back substrate. A light is irradiated on the ring-less getter from outside of the sealed vessel, thereby activating the ring-less getter.

A tab for fixing a paper web end portion of a paper roll includes a substantially parallelogram-shaped base sheet having two diagonally opposite acute angles. A plurality of linear, discontinuous cuts are formed on the base sheet in parallel with two opposite sides of the base sheet to thereby define a first portion in cooperation with one of the two opposite sides and a second portion in cooperation with the other side. The cuts extend to at least one of other two opposite sides of the base sheet. Adhesive is applied to the first and second portions on the same surface such that an appropriate nonadhesive portion is formed between adhesive applied onto the first portion and adhesive applied onto the second portion. A release sheet having a size greater than that of the tab is attached to an adhesive-applied side of the tab such that a portion thereof is projected beyond the profile of the tab. Alternatively, the release sheet assumes the form of tape. The tabs are arranged on the release sheet tape in the longitudinal direction of the tape. The release sheet tape is rolled up into a tab feed roll.
摘要:
A paper roll braking device for rotary presses, in which a web is paid off from a paper roll supported between frames, caused to travel, and printed in a printing unit, comprising rotors provided on supporting members for supporting the paper roll, braking sections provided at a plurality of locations along the rotors and having friction discs that can engage with, or disengage from, the rotors at their respective locations, engage/disengage changeover sections for controlling the engage/disengage operation of the friction discs with respect to the rotors, and a tension sensing mechanism for sensing changes in the running tension of the web; a contact pressure adjusting section for adjusting the contact pressure of the friction discs to the rotors via the engage/disengage changeover section in accordance with the changes in running tension detected by the tension sensing mechanism, an outside diameter detecting section for detecting the outside diameter of the paper roll, and an operation control section for switching the engage/disengage changeover section as the paper roll outside diameter detected by the outside diameter detecting section reaches a predetermined diameter are provided.

A wall is provided on one side of a web of paper or the like traveling along a predefined path, and an airstream is produced between the wall and the traveling web approximately in the direction of web travel. A transverse static pressure gradient is established across the airstream, causing the stream to flow close to the wall surface. This phenomenon is called as the Coanda effect. A partial vacuum created in the airstream causes the web to deflect from its normal path and to be drawn to the wall surface under sufficient pressure to be kept from fluttering. This method of web flutter control is applied to the splicing of webs, as from one roll to another in a web-fed rotary printing press. The web being unwound from the old roll has been susceptible to fluttering while being spliced to the new roll, such web fluttering being eliminable by providing a wall member along the web path and producing an airstream between the web and the wall member.

An inclined surface is formed in an upper inside wall of housing. The inclined surface inclines downwardly toward a lip seal. Lubricant oil supplied to the upper end of the inclined surface flows along the inclined surface without dropping downwardly due to surface tension, and flows to the lower end of the inclined surface then reaches the lip seal. Thus, the lubricant oil is supplied to the lip seal with certainty, thereby suppressing the wear of the lip seal and improving the durability of the compressor.

A performance of a compressor is enhanced and durability of scroll bodies is enhanced by optimizing relief to machining tolerance at a central end part of spiral members for forming the scroll bodies. In a scroll type compressor in which a reinforced portion (for example, a large radius of curvature R) reinforced more than in other root corner portions 5 is provided in a root corner portion 5 at a central end part in which a stress of the two spiral members 10 and 20 is increased, a first relief is formed in a region in which the two spiral members 10 and 20 come into contact with each other where the reinforced portion is applied only to one of the spiral members 10 and 20, and a second relief larger than the first relief is provided in a region in which the two spiral members come into contact with each other at a portion in which the radius of curvature R is provided in both of the two spiral members, thereby reasonably forming reliefs for avoiding interference at the point of contact of two spiral members.

A field emission type fluorescent display device capable of carrying out luminous display with increased reliability at an anode voltage 200V to 1000V and providing a desired luminous color by means of a filter. The fluorescent display device includes a luminous display section consisting of three display elements. The display elements include filters of red, green and blue colors on which light-permeable anode conductors are deposited, respectively. Then, the anode conductors have phosphors of the same colors as the filters deposited thereon, respectively. The blue phosphor is made of ZnO:Zn substantially containing a blue color component. Thus, a combination of the blue filter and phosphor provides light of a blue color with increased efficiency.
