摘要:
An apparatus for delivering an article, in which the delivery passage per se must be moved, comprises a pair of delivery belts substantially parallel to each other and supporting members for supporting the delivery belts, a mechanism for turning the paired delivery belts with the ends of the supporting members acting as the centers of turning so that the paired delivery belts are separated from each other from the substantially parallel position.

A magnetic levitating transportation apparatus comprising a rail and a vehicle capable of travelling along the rails by a linear motor and caused to magnetically levitate by magnet units including permanent magnets and electro-magnets. The gap between the rail and each of the magnetic units is controlled by controlling the current supplied to the magnet units so that the current is substantially zero when the vehicle is in the levitated condition. One of the magnet units is movably mounted to the vehicle and moved by the piezoelectric actuator so that the gap between this magnet unit and the rail can be adjusted. The controller controls the piezoelectric actuator based on the current supplied to the magnet units.
摘要:
A magnetic levitating transportation apparatus including rails and a vehicle capable of travelling along the rails by a linear motor and caused to magnetically levitate by magnet units with electro-magnets. The gap is controlled by controlling the current supplied to the magnet units in response to gap sensors. The rails include rail gaps where the ends of two rail elements abut, and rail gap sensors are arranged to detect the rail gap. Thus, current supplied to one of the magnet units is disabled when the rail gap is detected, and the current to be supplied to the associated magnet unit is stopped. The current to be supplied to the associated magnet unit is determined from the outputs of the remaining gap sensors.

A multilayer printed circuit board which can surely establish interlayer connection with low resistance. The multilayer printed circuit board comprises: a first substrate having a conductive pattern on one face and a non-penetration connection hole on the other face, for exposing the conductive pattern to outside; a second substrate having a conductive pattern formed on a face opposed to the other face of first substrate and a conductive bump on the conductive pattern integrally. The first substrate and the second substrate are integrated by engaging the bump of the second substrate with the connection hole of the first substrate and by intervening a conductive cement between the bumps and the conductive pattern exposed to outside from the connection holes.

A plasma display panel (“PDP”) 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.

摘要:
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 (“PDP”) 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.
