Publication number: 20010007409Abstract: A cathode-ray tube according to the present invention is able to automatically correct a color shading caused due to a repulsion effect and the like, which occurs between electron beams. An electron gun for use with the cathode-ray tube according to the present invention includes beam apertures bored through a first electrode opposing a cathode disposed in an inline fashion. Further, beam apertures through which so-called side beams pass are bored with a predetermined inclination relative to the opposing cathodes. Consequently, an electron lens formed between the cathode and the first electrode becomes an axial asymmetric electron lens. A curvature of this electron lens is changed in response to a drive voltage of the cathode. When this curvature is changed, trajectories of electron beams are changed to cancel an influence caused by a repulsion effect. Thus, a color shading can be corrected automatically.Type: ApplicationFiled: January 10, 2001Publication date: July 12, 2001Applicant: Sony CorporationInventors: Yuuichi Suzuki, Hirotsugu Ishihara, Makoto Baba

Publication number: 20010007416Abstract: The expected power to be output from a synchronous motor is obtained based on a torque command value and revolution speed of the motor. Meanwhile electric power consumption is detected based on voltage and current actually applied to the motor.

Publication number: 20010007447Abstract: For example, a display element (1) formed by an organic EL element and a control element formed by a MOS transistor (2) are connected in series between a driving line (6) to be driven with a voltage or a current and a ground. A gate of the MOS transistor (2) is connected to a control line (7) through a nonvolatile data holding section such as a ferroelectric capacitor (3), and control data of the MOS transistor (2) can be held in a floating state. As a result, the ON/OFF data of each pixel are held in the floating state, and display data are rewritten to only a pixel to be changed in a display state of ON/OFF or the like and held data are displayed on a pixel which is not changed in the display data. Consequently, it is possible to obtain a nonvolatile display device capable of reducing power consumption and operating with a small battery.Type: ApplicationFiled: January 11, 2001Publication date: July 12, 2001Applicant: ROHM CO., LTD.Inventors: Haruo Tanaka, Takashi Nakamura

Publication number: 20010007448Abstract: A display apparatus includes a display section having pixel rows, and shift registers which drive the pixel rows. The pixel rows are classified into an upper blanking region, a vide display region and a lower blanking region, and a scanning period is classified into a vide display period and a blanking period. The shift registers are grouped into first to third groups such that the first to third groups are independently controlled. The first and third groups are subjected to shifting operations for the upper and lower regions during the blanking period, respectively. The first and third groups drives the display section such that blanking data is written into the upper and lower blanking regions during the blanking period, and the second group drives the display section such that video data is written into the video display region during the vide display period.Type: ApplicationFiled: January 8, 2001Publication date: July 12, 2001Inventors: Reiichi Kobayashi, Toshiyuki Noguchi
