A communications terminal selection unit acquires, upon receipt of a call origination request, presence information including terminal information on terminals available to a call terminator from a presence management unit, and selects a specific terminal, if there are a plurality of terminals available to the call terminator based on the presence information, based on terminal selection information in which at least whether communication quality or charge takes priority is defined beforehand by the call terminator, notifying a call transfer unit of the selected terminal as a transfer destination terminal for call transfer.

A solvent for cleaning that offers particularly superior results for cleaning pigment-dispersed photosensitive resin compositions used for forming color filters and black matrix patterns. The solvent for cleaning has a hydrogen bonding parameter (&#x3b4;) among the Hansen solubility parameters that falls within a range from 5 to 10.

A plasma display panel (&ldquo;PDP&rdquo;) is provided with a protrusion lower than barrier ribs on an inner surface of a back plate substrate, and a phosphor layer formed on a rib surface within a unitary emission unit including a surface of the protrusion, thereby realizing the PDP of high brightness, high luminous efficiency and long operating life. Also, the PDP has a structure, in which a portion of the inner surface of the substrate is opened to a discharge space directly or through a protective layer, so as to improve power consumption remarkably. Further, the invention provides a production of the PDP with superior whiteness by way of controlling a balance of each color with shape of the respective protrusions. Moreover, an electrode can be formed easily and precisely on an upper part of the protrusion by providing a sloped surface for at least one end in a longitudinal direction of the protrusion. As a result, the invention provides the PDP that is of low power consumption, high brightness, high luminous efficiency, and is capable of performing a speedy and stable electric-discharge and displaying white color of high color temperature.

The PDP of the present invention has first, second and third electrodes. Intervals between the first and second electrode is 0.2 mm or more. A plurality of third electrodes are formed. Protrusions which are shorter than ribs are formed between the plurality of third electrodes. The plurality of third electrodes are connected, in part, to one another or at least connected in part, such that they form a network. In the driving method of the PDP of the present invention, a self-erasing discharge is generated, and subsequently when a potential difference between the electrodes is increased, using the self-erasing discharge as a trigger, discharge is generated and light is emitted.

The invention relates to a method of disassembling a plasma display panel (&ldquo;PDP&rdquo;) for reutilization. A first method uses a component, which is thermally not contractible at a softening temperature of bonding material used for hermetically bonding a front and back plates, and positioned between the plates. The above component maintains or widens a space provided between the two plates when the PDP is heated, thereby facilitating disassembly of the PDP. The invention also provides a groove on a surface of either or both plates for communicating the bonding material to an exterior of the PDP. Softened bonding material can be drawn out or absorbed through the groove. Heating and cooling of the PDP may be made through a laminated graphite sheet placed on a surface of the PDP for uniformalizing thermal distribution. A second method separates a PDP into two plates by immersing the PDP in etching solution capable of selectively dissolving only lead glass, and melting the bonding material. A groove is provided between the perimeter of an image display screen and a bonded portion in order to prevent etching solution from permeating into the screen area. The groove is formed on the substrates in parallel with a longitudinal direction of electrodes. The separated plates are refurbished by restoring a deteriorated or defective portion into the original condition for use in manufacturing a new PDP.

Improved positive photosensitive composition for application of the lift-off technique comprises (A) an alkali-soluble resin and (B) a mixture of two photosensitive agents in admixture with the alkali-soluble resin, one being (i) a photosensitive agent which shows the tendency to form a resist pattern of a feature profile having a micro-groove upon exposure and the other being (ii) a photosensitive agent which does not show the stated tendency but shows the tendency to form a resist pattern having a rectangular or tapered cross-sectional feature profile upon exposure and using the composition, one can form half-a-micron meter and even finer conducting patterns, electrodes or insulation patterns in a highly reproducible manner.

An electrostatic image forming apparatus 1 comprises a sensitized drum 2 covered with a single, organic, photosensitive layer (OPC). This sensitized drum 2 is rotatable at a predetermined speed. A charging device 5 is disposed around the drum 2 for uniformly charging a surface of the OPC. A latent image forming device 6 is disposed downstream of the charging device 5 around the drum 2 for forming a latent image on the OPC. A developed image forming device 7 is disposed downstream of the latent image forming device 6 around the drum 2 for forming a developed image from the latent image. A distance from the charging device 5 to the latent image forming device 6 is defined with respect to a distance from the charging device 5 to the developed image forming device 7 by the following expression;

Proposed is an alkali-soluble, positive-working photo-sensitive resin composition which can be used as a material for forming a finely patterned resist layer on the surface of a metallic substrate such as tantalum to exhibit excellent adhesion of the patterned resist layer to the substrate surface. The composition comprises, in addition to a novolac resin as a film-forming agent and a naphthoquinone diazide group-containing compound as a photosensitizer, an aromatic compound having two benzene rings and at least five phenolic hydroxy groups in a molecule such as pentahydroxy and hexahydroxy benzophenone compounds as an adhesion improver.

A positive-working photoresist composition comprising a cresol novolac resin as the film-forming agent and a quinonediazido group-containing compound as the photosensitizing agent is admixed with a limited amount of a hydroxyalkyl-substituted pyridine compound so that great improvements can be obtained in the adhesive bonding of the resist layer to the substrate surface and in the stability of the composition by storage still without the problem due to the sublimed material from the resist layer during the patterning process.
