  • Patent number: 8293936
    Abstract: Provided is a method for producing n-propyl acetate capable of suppressing the deterioration of a hydrogenation catalyst to such an extent that the catalyst can be industrially used, for example, in the case where n-propyl acetate is produced by performing a hydrogenation reaction in the presence of the hydrogenation catalyst using, as a raw material liquid, a liquid containing allyl acetate or the like which has been produced from propylene, oxygen and acetic acid and obtained using a purification process such as distillation. In such a method for producing n-propyl acetate, the concentration of a formyl group-containing compound (such as acrolein, propionaldehyde or 2-methylcrotonaldehyde) and the concentration of an acryloyloxy group-containing compound (such as acrylic acid or allyl acrylate) in the raw material liquid are respectively set to 100 ppm by mass or less. As a result, the deterioration of the hydrogenation catalyst can be suppressed to such an extent that the catalyst can be industrially used.

  • Patent number: 7498088
    Abstract: There are provided a magnetic thin film utilizing a granular film and having excellent high frequency characteristics and a method of manufacturing the same, and a multilayered magnetic film and magnetic components and electronic equipment utilizing the same. A nonreactive sputtering is performed so that there is no oxidation of a magnetic metal, and a saturation magnetization is increased to increase a resonant frequency of permeability. Also, a multi-target simultaneous sputtering is combined with the nonreactive sputtering so that in a granular structure including magnetic grains and an insulating layer a size of the magnetic grains and a thickness of the insulating layer are optimized thereby ensuring a proper magnitude for a crystalline magnetic anisotropy within the grains and excellent soft magnetic properties.

  • Publication number: 20060232654
    Abstract: In a laser beam printer, an optimized output power of a laser beam can be obtained without using an expensive laser driving IC. A first comparator device 35 compares an output voltage of a photodiode 32 with a first reference voltage and a second comparator device 36 compares the output voltage of the photodiode 32 with a second reference voltage. A control unit 12 adjusts a duty ratio of a PWM signal outputted to a laser driving circuit 33 based on the output signals from the first comparator device 35 and the second comparator device 36, so that the output power of the laser beam emitted from the laser chip 31 can be optimized. Thereby, the expensive laser driving IC can be omitted, thereby enabling the reduction of cost of the image forming apparatus.
