IPC: G09G3/20
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To easily perform smooth scrolling. SOLUTION: The output value of a second clock counter circuit 7 for counting a clock of a frequency-divided timer clock is compared, by means of a comparator 10, with that of a third clock counter circuit 9 for counting a shift clock; then, until both output values coincide with each other, display data per common lines is shifted by the shift clock. The execution/stop of the shifting operation is performed through the input/cut-off of the timer clock and the shift clock.

Title: Method for correcting position information
Inventor: YURA AKIHIKO
IPC: G06F19/00
Filed: 1987-11-18
Abstract: PURPOSE:To correlate accurate object data by a method wherein an average of errors which vary according to a certain time rule is obtained at every frequency and this position error is fed back to correct a position data of data to be observed. CONSTITUTION:An object data correlating unit 1E consists of an updated data interpretation unit 4E, a correlation interpretation unit 5E and a position correcting register 6E which stores position correction values. This identifies whether observation data from two observation systems have the same object or different objects. Based on the identification results, the observed data from the two observation systems are correlated and input information is stored in an object data file 3E. A position error calculation unit 2E retrieves an observed data having the same object in the object data file 3E at a specific frequency, and calculates an error which varies according to a certain time rule from the position data. Then the position data of the object data correlating unit 1E is corrected by using the calculated position error.

Abstract: PURPOSE:To eliminate the need for a transmission system and to reduce the size and weight of the title device by installing wave plates to the inner side of rotors of ultrasonic motors having the annular rotors. CONSTITUTION:The 1st-3rd ultrasonic motors 101a-101c are formed to the annular shape and the 1st quarter-wave plate 104a, the halfwave plate 105, and the 2nd quarter-wave plate 104b are fixed respectively sequentially to the inner side of the 1st-3rd rotors 102a-102c. Incident light 107 of an arbitrary polarization state incident perpendicularly on the 1st quarter-wave plate 104a is, therefore, converted to exit light 108 of an arbitrary polarization state. Namely, the incident light 107 is converted to linearly polarized light by setting the 1st quarter-wave plate 104a at a suitable rotating position; in succession, the polarization of this linearly polarized light is converted to an arbitrary direction by setting the halfwave plate 105 at a suitable rotating position. Finally, the polarized light is converted to arbitrary polarized light by setting the 2nd quarter-wave plate 104b at a suitable rotating position. The size and weight of the device are thereby reduced.

Title: Disk array device
Inventor: YONEYAMA TADASHI
IPC: G06F3/06
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent system down due to a media error after power interruption is restored when the power interruption occurs while writing work is performed for a hard disk. SOLUTION: Even though transfer data from a host computer 5 are temporarily stored in a data buffer memory 9, a write/read controlling part 8 extracts the transfer data from it and outputs it to a hard disk drive 1 through an HDD inputting and outputting part 10. If power supply from a power supply unit 4 is stopped and power interruption occurs while the hard disk drive 1 performs writing, the writing is going to be stopped in the middle of a sector. However, a voltage detecting part 11 immediately detects that the power interruption occurs based on the detection of voltage drop and outputs a reset signal Rs to the hard disk drive 1. Then, the hard disk drive 1 performs a reset operation after finishing writing for one sector by a 'sector security function' being its general function.

Filed: 1992-10-05
Abstract: PURPOSE:To prevent the deterioration of the measuring accuracy even when the width of an object to-be-measured is changed by using a calibrating apparatus which has measuring elements for calibration of the width provided in pairs at the equal distance right and left from the center and, a shutting means for shutting the light between each pair. CONSTITUTION:Two detectors each having a built-in linear sensor are set via a gap. The calibrating apparatus has pairs of measuring elements E1-E5 for calibration of the width at the equal distance right and left from the center of a base plate 10. The distance or width of each pair E2-E5 is realized by covering the pair and shutting the light by the respective step F2-F5 provided in a cover plate 12. The center of each pair is agreed with the center of the two detectors, and the right-and-left direction is made coincident with the distance direction of the detectors. A calibrating coefficient for the distance of each pair is obtained from the difference between a true value of the distance and the measuring data of the distance by the detectors. The width of the object is corrected by selecting a correcting coefficient based on the range of the unprocessed data of the detectors, and accordingly the measuring accuracy is improved.
