  • Patent number: 8289598
    Abstract: Recording an image of a holographic stereogram includes providing an optical deflecting device in proximity to a hologram recording medium that is exposed with a stripe-shaped elemental hologram. Either an object beam or a reference beam is deflected, in a long side direction thereof, through the optical deflecting device to expose the hologram recording medium. The hologram recording medium is multiply exposed, at least twice, with different deflection angles of the optical deflecting device to cause the stripe-shaped elemental hologram to have a plurality of parallaxes in a long side direction of the stripe-shaped elemental hologram.

  • Patent number: 8064785
    Abstract: A fixing device according to this invention includes a heating roller, a heater driver, a thermistor, and a CPU. The heating roller has a heater and heats a recording sheet. The heater driver drives the heater. The thermistor detects a surface temperature of the heating roller. The CPU stops an operation of the heater driver when the surface temperature of the heating roller becomes higher than a predetermined temperature and, thereafter, causes the thermistor to perform detection of the surface temperature of the heating roller for a predetermined time period and issues an alarm about occurrence of a first abnormality when the surface temperature of the heating roller fails to drop in the predetermined time period.

  • Patent number: 7764560
    Abstract: A refresh method for a semiconductor memory device features high noise resistance, lower power consumption, and lower cost. All word lines of one or more memory cell blocks that have not been selected in a self refresh mode are controlled to have a floating potential substantially at ground level. Even when a word line and a bit line are short-circuited, this control prevents destruction of memory cell information, which may be caused by noise, and also prevents generation of leakage current. A fuse, etc., for preventing generation of leakage current is unnecessary, so that lower cost is realized.

  • Patent number: 7596361
    Abstract: A low noise amplification circuit comprises a low noise amplifier and a filter coupled to the input terminal of the low noise amplifier. The low noise amplifier comprises an amplifying element and a matching input circuit coupled to the input terminal of the amplifying element. When gamma.sub.s shows a reflection factor in the case that signals flow from the input terminal of the amplifying element to the output terminal of the matching input circuit, impedance conversion for setting the gamma.sub.s at a desired value is made entirely or in part by means of setting the output impedance of the filter at the value different from that of characteristic impedance.
