摘要:
In a printed circuit board manufacturing equipment, a pressing die includes a first pressing part, a second pressing part, and a frame part. A buffer member is disposed between a first surface of a laminated body and the first pressing part. The second pressing part has a portion facing a second surface of the laminated body and a portion facing the buffer member. The frame part surrounds a whole area of a side surface of the buffer member. Before pressing and heating, the laminated body, the second pressing part, and the buffer member define an escape space therebetween for escaping the buffer member deformed due to the pressing. A lip protrudes from the frame part toward the laminated body. The lip is deformed following the deformation of the buffer member and comes in contact with a surface of the second pressing part facing the buffer member.

An image forming material comprises an image forming layer disposed on a support and comprising (a) aqueous composition comprising a hydrophilic binder layer containing metal developing nuclei or their precursor compound, and water and (b) an organic composition comprising an oil-soluble development inhibitor which is a compound having a diazo group or azide group and a water-miscible organic solvent. An image is formed by exposing the image forming layer to patternized light and then contacting it with a developer containing reducible metal ions and a reducing agent thereby to form an image constituted by metal particles grown at the light-exposed parts.

An electro-optic device comprises a plurality of first electrodes provided on a top substrate and a second electrode provided on a bottom substrate, the first electrodes confronting the second electrode through electro-optical matter which will show electro-optical phenomena by the application of electric field, the first and second electrodes being connected through electrical elements such as resistors or capacitors to a variable voltage source. In this electro-optic device, the electric field applied between the first and second electrodes are partially changed by various means, for instance, by making the areas of the first electrodes different, or by varying the values of the electrical elements such as resistors or capacitors, as a result of which the electro-optical matter shows various electro-optical phenomena.
摘要:
A multilayer substrate includes an insulating base member having a plurality of resin films, an electric element embedded in the insulating base member, and a spacer. The resin films are made of a thermoplastic resin and stacked and attached to each other. At least one resin film has a through hole for inserting the electric element. The one resin film further has a plurality of protruding members. One protruding member opposes to another one protruding member so that the one and the another one contact and sandwich the electric element. The spacer is arranged between the one resin film and an adjacent resin film and is disposed at a base portion of one of the protruding members.
