Abstract: A method of fabricating a photoplate and a photoplate fabricated by the method. A mask blank, having a glass substrate and an electrically conductive opaque film coating over an upper surface of the glass substrate, is coated with a resist to form a resist film over the opaque film to produce the photoplate. Before applying the resin to the opaque film (3), a zone of an upper surface of the opaque film (3) is deteriorated in wettability to the resist so that the resist does not adhere to the deteriorated wettability zone (3a), the deteriorated wettability zone (3a) being away from a pattern forming area (1a) of the opaque film (3). Then, the resist is applied over the upper surface of the opaque film (3) to form the resist film (4), whereby the wettability deteriorated zone (3a) of the opaque film (3) is exposed for earthing the opaque film (3), without being covered with the resist.

In one aspect the inventive oxides have composition Ba 1-x K x BiO 3-δ , with x ≥ 0.3, and transition temperature T onset   c  ≥ 22K. in another aspect the oxides have composition ABiO 3-δ , where A is X 1-x-y M x M y , where M is an appropriate dopant element, M is an appropriate stabilizer element, and X is a large divalent element such as Ba, Sr, or Ca. In a still further aspect the oxides have composition A n+1 Bi n O 3n+1-δ , where n is a positive integer greater than 0 and typically less than about 6. These embodiments have a layered structure, in contradistinction from other members of the relevant oxide class. The materials are advantageously produced by a process that comprises heating of the starting materials in a closed system such that an alkali partial pressure greater than 1 atm. (typically greater than 10 atm.) results. Potential uses for the novel materials entail all those for which prior art superconductors have been proposed, or in which they have been used.

Abstract: A central processor interrogates concentrators via line trunk groups for temporarily stored data successively in a cyclic sequence. In each of the concentrators, it is monitored whether the time interval between in each case being interrogated and next being interrogated exceeds a predetermined time limit value. When the time limit value is exceeded, the relevant concentrator continuously repeatedly reads the data out of its store and transfers them to the central processor. Concentrators are set up for interworking with the central processor and with line trunk groups of in each case a relatively old and relatively new type of construction. The extent of the data to be transmitted on the basis of being interrogated depends on this. The concentrator stores the type of construction feature. When the time interval is exceeded, the temporarily stored data are transmitted as determined by the type of construction feature stored in each case. <IMAGE>

The shaped gel then is employed in a first treatment step to form a treated sample that may be a separated sample. After extrusion of the gel from the tube, the portion of the thread extending from each end (26, 28) of the shaped gel is grasped and the shaped gel containing the treated sample is transferred to contact a slab gel (30) along the entire length of the shaped gel to effect an electrophoresis step in the second treatment step.
