  • Patent number: 10122880
    Abstract: An image forming apparatus includes a fixing portion, a temperature detection portion, a power supply portion, a control portion, a photovoltaic module and a power storage/supply portion which stores power from the photovoltaic module and which performs power supply to the temperature detection portion when power supply from the power supply portion to the temperature detection portion is stopped. The control portion detects, when a return condition is satisfied, the temperature of the fixing portion based on the output of the temperature detection portion, and as a temperature on return is higher, the control portion starts fixing return processing at later timing whereas as the temperature on return is lower, the control portion starts the fixing return processing at earlier timing.

  • Patent number: 8723906
    Abstract: This image-forming apparatus includes a plurality of photosensitive drums, a plurality of laser scanning units, and a motor control unit. A motor control unit detects the time difference between a change point of the detection signal of a reference color and the change points of colors targeted for phase correction, and, when the absolute value of the time difference is greater than a threshold, carries out a rough adjustment process for reducing the time difference by a drive signal with which a base period has been changed by a first period change amount and thereafter carries out a fine adjustment process for reducing the time difference by a drive signal with which the base period has been changed by a second period change amount smaller than the first period change amount.

  • Patent number: 5818420
    Abstract: A 3D object graphics display device for storing information about 3D objects such as works of art or buildings, and for displaying them on a 2D display. The "3D shape data" and "texture data" of a 3D object is stored in a memory in advance. When an operator operates a manipulator, a 2D image is generated, which would be acquired when the 3D object is seen from a viewpoint indicated by the manipulator, by using the 3D shape data and the texture data in every 1/60 sec or less interval (that is, a minimum display interval of the display device). The 2D image is shown on the display, giving the operator a virtual-reality-like feeling as if he was actually holding the 3D object.

  • Patent number: 5703637
    Abstract: A retina direct display device provides an observer with the display of a plane image or a stereoscopic image. The retina direct display device is, for example, incorporated with an acoustic device to constitute a television receiver. The retina direct display device comprises a visible light conversion means, a retina projection means and an eye movement tracking means. The visible light conversion means converts an input video signal to a beam of visible light. The retina projection means deflects the beam horizontally and vertically so that retinas are raster scanned through pupils of both eyes by the deflected beam. The eye movement tracking means detects the movement direction of the pupils and permits the direction of the beam emitted from the retina projection means to track the movement of the pupils based on the result of the detection.

  • Patent number: 5471323
    Abstract: By applying the offset sampling using four-plane prism provided with four solid state imaging devices at four light output planes, chromatic aberration of lenses is eliminated even to the peripheral part of the imaging plane, and moire suppression effect is much enhanced. Furthermore, by using a plural number of matrix circuits, and by producing the luminance signal by changing the matrix ratios in low frequency range and in high frequency range, moire suppression effect is further enhanced, and luminance error is also eliminated.

  • Patent number: 5363384
    Abstract: A digital audio signal demodulation circuit comprises a synchronous detection circuit (18) and a muting circuit (17) for muting the output from an interpolation circuit (16) using a synchronization lock signal generated from the synchronous detection circuit (18) when synchronization has been lost. The differential signal output from the interpolation circuit (16) is muted by the muting circuit (17) and thereafter integrated by an integration circuit (19). Thus, an audio signal with high sound quality can be demodulated without producing interruption noise even when synchronization has been lost or forcible muting is done.

  • Patent number: 5163053
    Abstract: An audio signal demodulating circuit comprises a counter circuit (11) for detecting the number of samples for which interpolation is to be successively made by counting the output from an error correction circuit (2) and an AND circuit 10 for taking the logical product of the output from the counter circuit and the mute signal generated when synchronization has been lost. If interpolation is to be successively made for m (integer) or more, an audio differential signal is muted using a mute signal so as to remove the signal with greatly deteriorated audio quality. This can remove large audio distortion generated if interpolation is only successively made for error correction when errors successively occur for samples.

  • Patent number: 5153724
    Abstract: The present invention provides an apparatus which receives and displays a high definition television signal and which is constructed so that noise and/or a deformed picture may not be displayed even when an input signal instead of a high definition television signal is applied or when transmission of such a high definition television signal is interrupted. In the apparatus, on the basis of whether or not a frame signal in an input high definition television signal can be detected, a first signal indicating synchronization lock or a second signal indicating synchronization unlock is generated so that, when the first signal is detected, the output of a signal processing circuit (110) is selected to display the high definition television signal, while when the second signal is detected, the output of a pattern generation circuit (114) is selected to prevent display of noise etc.
