摘要:
A mold surface of an upper mold with which a fluid resin comes into contact has an oxide therein. The oxide contains a metal cation and an ion. Field strength is calculated based on a valence of the metal cation and ionic radius of the ion. Based on predetermined relationship established between a value of the field strength and adhesion strength between a cured resin and the mold surface, releasability between the cured resin and the mold surface is evaluated. Thereby, a method of evaluating releasability between the cured resin and the mold surface is established. With this evaluation method, a material with high releasability can readily be provided. Further, if the material with high releasability is used for the mold surface of the upper mold, a mold for molding a resin having excellent releasability can be obtained.

A conductive porous material includes a matrix having a sintered compact of an oxide, a communicating opening formed in the matrix, having a small diameter and being permeable to gas and impermeable to substance other than gas, and a conductive layer provided on an internal wall of the communicating opening and receiving a current to generate heat. As conductive material is used, an organic substance adheres on the internal wall of communicating opening. To address this, conductive layer is caused to generate heat to decompose and thus remove the organic substance and thus prevent the communicating opening from clogging.

A low-adhesion material containing a rare-earth element is formed as a layer or a film on a mold surface of a mold for molding a resin. A main component of the low-adhesion material is a rare-earth compound, and Y2O3 is used as an example. A content of the rare-earth compound in the low-adhesion material is not less than 40 percent by volume. Thereby, a mold for molding a resin having excellent releasability can be obtained.

摘要:
The present invention relates to a composite material used for a resin mold for forming hardened resin by hardening fluid resin. The composite material comprises a first material having excellent wear resistance against the fluid resin and a second material having excellent unwettability against the fluid resin. The resin mold comprises a substrate of the first material, a large number of pores each provided to form an opening on a surface of the substrate opposite to the fluid resin and a film of the second material formed along the inner wall surface of each pore at least around the opening. Each of the large number of pores is a communicating hole connecting the surface opposite to the fluid resin and the remaining surface with each other. Therefore, releasability between a mold surface and the hardened resin and wear resistance of the composite material against the fluid resin can be improved.

A resin casting mold used for manufacturing a casting product including a cured resin produced by curing a fluid resin filling a cavity includes: a block providing the bottom surface of the cavity; and a driver mechanism for applying a force to the block to move the block in a direction that lies along the bottom surface. The driver mechanism moves the block when the cured resin has been formed to separate the cured resin from the bottom surface. This arrangement allows a thinner casting product with a larger major surface to be properly separated from the cavity surface without damaging the casting product and with high driving efficiencies and without equipment including a resin casting mold with a complicated structure or a large size.

A transmission source bridge collects packets sent from nodes connected to a serial bus in accordance the IEEE1394 Standards, into one packet in an order they are to be transmitted and then sends them onto an ATM network, so that a transmission destination bridge receives this packet and divides it into a plurality of smaller packets and transfers them, in the order they were sent, to nodes connected to the serial bus in accordance with the IEEE1394 Standards.

Provided are a curable resin and a curable resin composition which have alkali-solubility and curability that can freely be adjusted and a high sensitivity, a liquid crystal panel substrate which can maintain an even cell gap, and a liquid crystal panel using the liquid crystal panel substrate to exhibit a superior display quality. A curable resin composition comprising an imide-containing copolymer having a molecular structure wherein a constitutional unit at least the following units are connected: a constitutional unit having a cyclic imide group represented by the formula (1), a constitutional unit having an acid functional group such as a carboxyl group; and a constitutional unit having a photopolymerizing functional group. In a liquid crystal panel substrate (color filter 103), plural spacers (column-shaped spacers 12) are disposed in a non-display region on a substrate 5.
