Title: Bias error estimating device for sensor
Inventor: KIMOTO EIJI
IPC: G01B21/00
Filed: 1993-11-29
Abstract: PURPOSE:To calculate a bias error with high reliability by using suck a mathematical method as taking a bias error of a reference sensor as a state variable after obtaining an observation matrix of an observing device, and obtaining a covariance matrix of a bias error estimated value. CONSTITUTION:A reference sensor 1 and sensors 2-3 observe a target position, target positions are output from a reference observing device 4 and observing devices 5, 6, and the target observing positions of sensors 2-3 are calculated by adders 9-10. An observation matrix generator 12 obtains an observation matrix from the target observation positions and a bias error initial value from an initial bias setting device 11, and an estimated value evaluating device 13 obtains a covariance of an estimated value from the matrix. An estimated value calculating device 14 obtains a virtual vaue of a bias error estimated value from both matrixes, and a difference between the initial value and the virtual value is obtained by a subtracter 15 to output a bias error estimated value 16 of the sensor 1. Further, an alignment error from an alignment error setting device 7 is added by an adder 17 to calculate bias errors of the sensors 2-3.

Abstract: PURPOSE:To prevent the over-etching of a first electrode layer by coating the upper surface of the first electrode layer with a protective film smaller in the etching rate than an interlayer insulating film. CONSTITUTION:A first eiectrode layer 6 coated with a protective film 4 with a desired pattern is formed.

Title: Driving method for thin-film el display device
Inventor: SAKAMOTO ATSUSHI
IPC: H05B44/00
Filed: 1989-11-15
Abstract: PURPOSE:To immediately erase the charge remaining in an EL element and to obtain stable light emission luminance by using the pulse voltages of the waveform higher in the crest value of the front part than the rear part of pulses as the voltages to be impressed to picture elements. CONSTITUTION:The EL element of a 3-layered structure is interposed between scanning side electrodes S 1 to S 4 and data side electrodes D 1 to D 8 of crossed arrangement. The modulating voltages changed in pulse width or amplitude are impressed according to display data on the electrodes D and the writing voltages are successively impressed to the electrodes S to make gradation display. The ramp voltages of the waveforms decreasing in the crest value from the front part to the rear part of the pulses are used as the writing voltages VW1 to VW2 to be applied to the scanning side electrodes S 1 to S 4 at this time. The high voltages exceeding the light emission threshold are, therefore, applied on the picture elements in the initial stage of the effective voltage impression and the accumulation of charges in the light emitting layer of the thin-film EL element is eliminated in a non-lighting state B0. The excessive brightening is obviated even when the element is next switched to the light emission state. The stable gradation display is thus executed.

Title: Method and device for detecting zero position of hand in analog display quartz clock and clock provided with said device
Inventor: RENE BETSUSON
IPC: G04C9/00
Filed: 1990-11-02
Abstract: PURPOSE: To minimize the usual supply power for reducing power by calculating a position to maximize the output signal of a detecting element and cause the position to correspond to the zero point position of a clock hand in assembling the clock. CONSTITUTION: A second motor may miss the step when a large impulse is applied. Then, a signal 54a stops at 0. Thus, control systems 25-26 advance the motor by 1 step and a threshold value is compared with a current ratio with respect to at least three arrangements so that it is repeated until current in greater than threshold value is obtained in all arrangements. At this time a second hand reaches 0 position, while this operation is very quickly carried out, i.e., only 9 milliseconds is taken for the advance of 1 step and 1 millisecond or less is taken for the test of position. Thus, 60 continuous positions of the second hand can be tested in 0.5 seconds. Larger power than the usual one is required for the motor only in such a operation to elongate the control pulse and ensure the correction, thereby minimizing the usual supply power and reducing the power.
