Abstract: A base conductive member is formed on a surface and in a hole section of a substrate, and a resist is formed on a part of the base conductive member in which a conductive layer is not to be formed. The conductive layer is formed on a part except for the part in which the resist has been formed, and a mask metal is formed on the conductive layer. Then, the resist is removed, and the base conductive member is etched using the mask metal as a mask to form the conductive layer into a predetermined shape.

Abstract: As shown in FIG. 7, a data receiver receives video data and audio data together with a frequency division parameter N that depends on the pixel clock of the video data and the sampling frequency of the audio data, and a count value CTS that is obtained by counting the period of the audio clock that has been subjected to frequency division by the frequency division parameter N, with the pixel clock, which are transmitted from a data transmitter, and subjects the pixel clock to frequency division by the count value CTS, phase-control the divided clock (s501) in accordance with a phase comparison clock (s505) that is obtained by dividing an audio clock (s403) oscillated from a VCO (504) by the frequency division parameter N, thereby generating an audio clock (s403). Accordingly, the data transmitter and the data receiver can satisfactorily implement multiplexing of audio data and video data, and transmission of the multiplexed data using an existing DVI cable, with a simple structure.

Abstract: When liquid materials are fed to inkjet heads, fluid pressures are equalized so that a gas does not remain in liquid feed pipe lines. Separate liquid feed pipe lines (3) for feeding the liquid material, each of which communicates with each of a plurality of inkjet heads (4), are each connected to a common liquid feed pipe line (2) which stores one kind of the liquid material and communicates with an ink tank (1). Separate gas flow pipe lines (19), each of which is capable of feeding a gas and communicates with a connection portion between the common liquid feed pipe line (2) and each of the separate liquid feed pipe lines (3), with each of the inkjet heads (4), or with both the connection portion and each of the inkjet heads (4), are each connected to a bypass pipe line (18a).
Abstract: The present invention relates to a method for production of a coated preparation, characterized by coating a core material with a coating solution, the core material comprising an active ingredient, the coating solution comprising a) a resin composition obtained by copolymerization of polyvinyl alcohol having an average polymerization degree of 1300 or less, and at least one polymerizable vinyl monomer in a weight ratio of 6:4 to 9:1, b) water, and c) an organic solvent. The method for production make it feasible to efficiently coat a preparation such as a tablet, a granule, and a fine granule, etc. (a pharmaceutical drug, an animal drug, an agricultural chemicals, a fertilizer, or a food product) with the coating solution comprising a) the composition comprising the polyvinyl alcohol copolymer as the main component, b) water, and c) the organic solvent.
Abstract: A flight control system according to the present invention includes a first sensor, a flight control computer, a link mechanism, a separation unit, and a second sensor detecting a force transmitted from the first control lever to the link mechanism. The first sensor detects a force applied from an outside to a first control lever. The flight control computer determines whether or not sticking arises in the first control lever on the basis of the force detected by the first sensor and the force detected by the second sensor, and outputs a separation command to the separation unit when determining that the sticking arises. The separation unit disconnects the link mechanism on the basis of the separation command to separate a connection between the first control lever and the second control lever.
Abstract: A complex type microscopic device includes a slider unit moving a stage, an optical microscope, a scanning electron microscope with an electron axis intersecting with an optical axis of the optical microscope, an optical measurement/observation unit having a magnification between those of the scanning electron microscope and the optical microscope and co-using an objective lens with the optical microscope, and a control unit controlling the entire device, and a display unit having a display screen. During display of a low-magnification optical microscopic image, the control unit controls the display unit to display, on the image, a representation to designate an area to be observed at a magnification of the optical measurement/observation unit, and to display, on the image, another representation to designate an area to be observed at a magnification of the scanning electron microscope during display of a high-magnification optical microscopic image.
