  • Patent number: 8089442
    Abstract: An image projection apparatus is disclosed which projects an image having a good color by reducing the influence of a lateral electric field in a liquid crystal display element (LCD). The apparatus includes three LCDs, each including two opposite electrodes. As the voltage applied to a liquid crystal layer is increased, retardation provided for light in each color band is increased. A controller controls an electrode application voltage in the first LCD such that, in a white display state, a liquid crystal application voltage (LCAV) in the first LCD is lower than the LCAVs in the second and third LCDs, and such that, in a black display state, the LCAV in the first LCD is higher than the LCAVs in the second and third LCDs and has a value from 1% to 30% of the LCAV in the first LCD in the white display state.

  • Patent number: 8037739
    Abstract: A method for analyzing a sample in a liquid is provided, which is suitable for easily and reliably preventing a liquid for analysis from being evaporated. When the sample in the liquid is observed by using a scanning probe microscope (SPM), a sealing liquid (17) immiscible with a liquid for analysis (16) is filled around the liquid for analysis (16), in which a sample (13) and a probe (15) are immersed, so as to form a sealing state, in which the liquid for analysis (16) is isolated from an external gas. The SPM enables the probe (15) disposed on a front end of a cantilever (14) to approach a surface of the sample (13) immersed in the liquid, scans the surface of the sample, and detects an interaction between the sample (13) and the probe (15), thereby generating an image.

  • Publication number: 20110174418
    Abstract: The present invention solves the problem of melting of Al in heating before hot-stamping, which had been a problem in the past in applying hot-stamping to Al-plated steel sheet, and provides Al-plated steel sheet for hot-stamping and a method of hot-stamping using that Al-plated steel sheet to solve the problem of delayed fracture due to residual hydrogen, and, furthermore, a method of a rapid heating hot-stamping using that Al-plated steel sheet. The Al-plated steel sheet of the present invention is produced by annealing the Al-plated steel sheet as coiled in a box-anneal furnace for the time and at the temperature indicated in FIG. 5, and alloying of a plated Al and a steel sheet. Further, a method of rapid heating hot-stamping in the present invention is characterized by cutting out a stamping blank of an Al-plated steel sheet, and heating that blank in heating before hot-stamping by an average temperature with a rising rate of 40° C./sec or more and a time of exposure to an environment of 700° C.

  • Patent number: 7975316
    Abstract: A frequency shift ?f obtained by an FM-AFM can be expressed by a simple linear coupling of a ?fLR derived from a long-range interaction force and a ?fSR derived from a short-range interaction force. Given this factor, a ?f curve on an atomic defect and a ?f curve on a target atom on the sample surface are each measured for only a relatively short range scale (S1 and S2), and a difference ?f curve of those two curves is obtained (S3). Since the difference ?f curve is derived only from a short-range interaction force, a known conversion operation is applied to this curve obtain an F curve which illustrates the relationship between the force and the distance Z, and then the short-range interaction force on the target atom is obtained from the F curve (S4). Since the range scale in measuring the ?f curve can be narrowed, the measurement time can be shortened, and since the conversion from the ?f curve into F curve is required only once, the computational time can also be shortened.

  • Patent number: 7842142
    Abstract: High-strength parts and a method for producing them can be provided, where such parts exhibit hydrogen embrittlement resistance and strength after high-temperature forming. For example, the atmosphere in a heating furnace can contain less than about 10% hydrogen and/or have a dew point of about 30° C. or less. The amount of hydrogen penetrating a steel sheet during heating can thereby be reduced. After forming, quench hardening in a die assembly and post-working can be performed. Post-working can include shearing followed by re-shearing or compression forming; punching with a cutting blade having a continuously reduced base width; punching with a tool having a curved blade and a protrusion at the tip of the cutting blade, where the curved blade may include a shoulder portion of given radius and/or angle; fusion cutting; etc. Tensile residual stresses after punching can be reduced and resistance to hydrogen embrittlement can be improved.
