  • Patent number: 9505165
    Abstract: A nanoimprinting mold includes: a mold main body having a fine pattern of protrusions and recesses on a surface thereof; and a mold release layer formed on the surface of the mold main body. The mold release layer is formed within a mold release layer forming region, which is a region of the mold main body that includes a patterned region where the fine pattern of protrusions and recesses is formed and has an outer edge positioned outside the outer edge of the patterned region. An outer peripheral mold release layer has a thickness distribution in which the thickness of the outer peripheral mold release layer is locally maximal at positions outside the outer edge of the patterned region, substantially continuously along the entire periphery. Thereby, it becomes possible to restrict the region in which resist flows during nanoimprinting, without employing a mesa type substrate.

  • Publication number: 20140210140
    Abstract: A nanoimprinting method employs a resist composition including polymerizable compounds and a polymerization initiating agent, each having absorption spectrum properties with absorption regions within a range from 250 nm to 500 nm. The polymerization initiating agent has an absorption region with a longer wavelength end wavelength longer than the longer wavelength end wavelength of the absorption region of the polymerizable compounds. Further, exposure of the resist composition is executed by light having spectral intensity properties that satisfy a predetermined relational formula. The present invention enables contamination of molds by adhered matter to be suppressed, and enables formation of resist patterns having sufficient etching resistance by nanoimprinting.

  • Publication number: 20140001675
    Abstract: In a nanoimprinting method, an assembly, of which the entire surface is directly exposable to the environment, is supported by a pressure vessel by a support member such that fluid pressure from the environment operates on the entire surface of the assembly. Gas is introduced into the pressure vessel, and fluid pressure exerted by the gas presses a mold and a substrate against each other. Thereby, pressing with uniform pressure onto a curable resin coated surface can be realized in nanoimprinting that employs a mesa type mold and/or a mesa type substrate to be processed, and the occurrence of residual film fluctuations can be suppressed.

  • Patent number: 4872829
    Abstract: A fire-extinguishing device for an open-type oil burner is disclosed which is capable of effectively preventing the discharge of bad odor to a room due to unburned fuel oil gas at the fire-extinguishing of the oil burner. The fire-extinguishing device includes a damper for closing, at the fire-extinguishing, an opening of a combustion cylinder construction of the oil burner through which combustion gas is discharge to a room. The damper or combustion cylinder construction may be provided with an oxidation catalyst plate through which combustion gas is discharged to a room at the fire-extinguishing, so that unburned fuel oil gas may be removed by means of the catalyst plate.

  • Patent number: 4797088
    Abstract: A safety device for an oil burner is disclosed which is capable of detecting abnormal combustion which forms an excessively decreased flame, for example, sufficient to produce incomplete combustion gas to operate a fire-extinguishing device of the oil burner. The safety device includes an abnormal combustion sensing and actuation mechanism which is adapted to receive heat rays from the oil burner to detect the abnormal combustion and a starting member selectively actuated by the mechanism to operate the fire-extinguishing device when the mechanism detects the abnormal combustion.

  • Patent number: 4726762
    Abstract: A wick actuating device of the lever actuation type for an oil burner is disclosed which is capable of not only vertically moving a wick but variably setting the ignition position of the wick as desired. The wick actuating device includes an operation lever loosely fitted on a wick operating shaft, a shaft actuation lever fixedly fitted on the shaft and a connection mechanism for connecting both levers to each other. The connection mechanism includes a slit formed at the operation lever and a pin slidably mounted on the shaft actuation lever and movably fitted in the slit. The slit is formed to be oblique with respect to the sliding direction of the pin so that the operation lever is engaged with the shaft actuation lever through the slit and pin at an angle which is varied depending upon the position of the pin in the slit.
