  • Patent number: 10840449
    Abstract: A method for producing a resin film by using a resin material and accurately forming a fine pattern as a vapor deposition mask or an optical element, a method for producing an organic EL display device, a base film for forming a fine pattern and a resin film with a supporting member are provided. A liquid resin material is applied onto a supporting member to form a resin coating film (S1), and a temperature of the resin coating film is increased to a temperature at which the resin material cures, to form a baked resin film (S2). Thereafter, a base film formed by the baked resin film attached to the supporting member is processed by irradiating with lasers, to form a resin film (1b) having a desired fine pattern and the supporting member (S3). Thereafter, the baked resin film on which the fine pattern is formed is peeled from the supporting member, and the resin film having the fine pattern is obtained (S5).

With the rotation of a rotating drum (4), workpiece (w) is transported in the direction of the line of the central axis along the inner circumferential surface part on the lower side inside the rotating drum by spiral workpiece transport fins (8) formed along the inner circumferential surface inside the rotating drum. During transport with the rotation of the rotating drum (4), the washing configuration for the workpiece is switched from immersion washing to flowing water washing and shower washing in that order.

  • Publication number: 20100310828
    Abstract: [Object]To provide a substrate processing method capable of forming a concavo-convex structure on a substrate surface while reducing the number of processes. [Solving Means] In a substrate processing method according to the present invention, particles are dispersed on a surface of a substrate, and a concavo-convex structure is formed on the surface of the substrate by etching the surface of the substrate with the particles as a mask and the mask is simultaneously removed by the etching. According to this method, a process of removing the mask from the substrate surface after the concavo-convex structure is formed becomes unnecessary. Accordingly, since the number of processes necessary to form the concavo-convex structure on the substrate surface is largely reduced, it becomes possible to greatly improve productivity.

  • Publication number: 20090066976
    Abstract: A printing apparatus free from contamination of dust into a coated layer is provided. A printing apparatus of this application includes a first ejecting head and a printing head. The first ejecting head is located on a leading side in a moving direction D of the printing head. Since electric charge is removed from an object to be printed and dust is removed therefrom, by blowing an electric charge-removing gas through the first ejecting head before an ink lands on the object to be printed, dust does not contaminate a coated layer. In addition, since a suction hole is arranged between an ejecting hole and a nozzle zone, a stream of the electric charge-removing gas is not formed in the nozzle zone, and thus a meniscus of nozzles is not disturbed.

  • Publication number: 20080210546
    Abstract: A transparent electroconductive film having a small resistance value and a high transmittance and causing no damage upon an underlying organic EL film is formed. First and second targets are spaced and arranged in parallel, and a shielding plate is provided between the space and a transporting path for an object to be film-formed. Sputtered particles are allowed to reach the object through a release hole formed at the shielding plate. The sputtering particles obliquely irradiated are shielded by the shielding plate so that the transparent electroconductive film having a low resistivity and high transmittance can be formed.

  • Patent number: 6734752
    Abstract: A concentrated constant type isolator includes an upper member, a lower member, a resin case, a center electrode assembly, a permanent magnet, a resistor element, matching capacitor elements, and a resin member. By setting the electrostatic capacitance value of the matching capacitor element on the input terminal side and that on the output terminal side to appropriate values, the reflection loss characteristic of the concentrated constant type isolator is set such that the center frequency in a pass band is located between the frequency at which the input-side reflection loss becomes a maximum value and the frequency at which the output-side reflection loss becomes a maximum value, and such that the frequency at which insertion loss becomes the minimum value is close to the center frequency, whereby the standard of the insertion loss is satisfied.

  • Patent number: 6542759
    Abstract: A radio communication apparatus has a switch for indicating occurrence of emergency, a speaker, a speaker driver for emitting an alarm sound by driving said speaker in response to the operation of the switch, and a transmitter for transmitting a predetermined alarm signal by radio. When an emergency condition occurs to an owner of the radio communication apparatus, the radio communication apparatus emits an alarm sound from the speaker and emits an alarm signal by radio in response to a switching operation. Therefore, a person a short-distance away will be informed of an emergency by sound, and a person a long-distance away will be received by using a radio.
