  • Publication number: 20140000517
    Abstract: Disclosed is a coating apparatus capable of enhancing the film thickness uniformity. The coating apparatus includes a nozzle and a moving mechanism. The nozzle includes a storage chamber that stores a coating liquid and a slit-like flow path that is in communication with the storage chamber, and discharges the coating liquid through a discharge port formed at a front end of the flow path. The moving mechanism moves the nozzle and the substrate relatively to each other along a surface of the substrate. Also, in the flow path provided in the nozzle, flow resistance at the central portion in the longitudinal direction is larger than that at both end portions in the longitudinal direction.

  • Publication number: 20050283440
    Abstract: A license evaluation apparatus and method is disclosed which can specify the substance and the position of an error only with a simple description without the necessity to analyze the error in an ex post fact fashion. A data storage section stores licenses, and a content selection section selects a content. A license extraction section extracts the license from within the data storage section. A conditional expression decision section reads a conditional expression in use condition information of the license and an error code annexed in advance to the conditional expression and deciding whether or not the conditional expression is satisfied. If the conditional expression is not satisfied, an error code retaining section retains the error code. An application to which the error code is returned can specify the error without analyzing the error in an ex post fact fashion.

  • Patent number: 6804875
    Abstract: An elastic wave generator includes an excitation coil, a magnetostriction oscillator around which the excitation coil is wound and an oscillator support. The excitation coil is wound around the oscillator, which is made of laminated magnetostriction sheets having a positive strain characteristic, in which length varies directionally upon magnetic excitation. The oscillator support has a first support surface bearing against a first end surface of the magnetostriction oscillator, intersecting the direction along which the length of the magnetostriction oscillator changes and a second support surface shrink-fit against a second end surface of the magnetostriction oscillator, intersecting the direction along which the length of the magnetostriction oscillator changes. Thus, the changes in the length of the magnetostriction oscillator due to the magnetic excitation of the excitation coil appearing at the first and second end surfaces is directly supported by the first and second support surfaces.

  • Patent number: 6709281
    Abstract: The write protect switch SW comprises a first piece of metal (50) formed from a stationary metal piece and a second piece of metal (40). The touching portion (46) of the second piece of metal (40) that comes in contact with one of the slide positions of the write protect button (3) in the recess (2) is situated generally at the center position between the contact portion (45) and the holding portion (42) of the second piece of metal (40) or on the holding portion (42) side of the center position. This arrangement ensures a reliable, stable separably connecting operation of the two pieces of metal (40, 50) and provides a necessary contact pressure between them so that the position of the write protect button (3) can be detected accurately and reliably.
