Title: Method for detecting position of vehicle body
Inventor: YAMAMOTO SHIGEHIRO
IPC: G05D1/02
Filed: 1988-10-20
Abstract: PURPOSE:To reduce error amount included in a vehicle body position operation value by comparing the large-small relations of the mutual differences of an operation value by the rolling distance detection value of a right and left measuring wheels, an operation value by the directional detection value by a caster wheel and an operation value by the steering angle of a steering wheel, concerning the operation value of the directional change amount of a vehicle body. CONSTITUTION:Concerning the successive value operation of the directional change amount of the vehicle body 1, the large-small relations of the mutual differences of a value DELTAtheta1<i> operated by the rolling distance detection value of two right and left measuring wheels 4 fitted on an axis 3 on which the turning center of the vehicle body 1 is, a value DELTAtheta2<i> operated by the directional detection value of a caster wheel 5 fitted in the arbitrary position of the vehicle body 1, and a value DELTAtheta3<i> operated by the steering angle detection value of a steering wheel 7 fitted in the arbitrary position of the vehicle body 1 are compared. One of two combinations whose differences are minimum is selected as the surest value and a vehicle body position operation is performed by using the value. Thus, the error amount included in the operation value can be reduced.

Abstract: PURPOSE:To relax the accuracy of capacitance ratio and to reduce number of capacitors and total capacitance by providing a capacitor for storing a sample value to a feedback loop of an operational amplifier and comparing the sample value and the reference value while the subtraction of a prescribed charge from the charge in the capacitor is being repeated. CONSTITUTION:A sample value holding capacitor C6 is provided to a feedback loop of an operational amplifier A1 and a prescribed charge is subtracted by transferring it from the charge of the capacitor C6 into the capacitor C4 having a reference capacitor. The operation is repeated for several times till the output voltage of the operational amplifier A1 reaches a reference voltage Vr to decide the bit sign of the high-order neveral bits. When the output voltage V4 of the operational amplifier A1 reaches the reference voltage Vr or below, the charge transfer of the capacitor C6 for holding sample value is stopped tentatively, the charge in the capacitor C6 is doubled to apply charge transfer thereby deciding the bit sign of the next several bits. The operation above is repeated for a required cycle to convert the sample value into a digital signal. Thus, the total capacitance, number of capacitors are decreased and the capacitance ratio accuracy is relaxed.

IPC: H04B10/00
Filed: 1989-10-12
Abstract: PURPOSE:To improve the resolution by arranging plural non-rectangular apertures each having orthogonal symmetrical axes on a line. CONSTITUTION:The shape of a photodetector, i.e., the aperture is non- rectangular with orthogonal symmetrical axes and plural elements are arranged on a line. The non-rectangle with orthogonal symmetrical axes is referred to as rhombus, hexagon, octagon, petal surrounded by sinusoidal waves symmetrically or equivalent. Thus, the pitch of a columnar symmetrical axis of each aperture is 2b and the axes are in parallel with each other, the pitch of the symmetrical axis in the axial direction is 2a, and the axial symmetrical axis of other row exists between the axes of one row and no space exists among adjacent apertures. Thus, the output is subject to high resolution by having only to vary the shape of the aperture and the arrangement without increasing the arrangement density of the photodetectors and the element arrangement number, noise due to pseudo resolution is reduced and a sharp picture is obtained.

Abstract: PURPOSE:To make it possible to measure the thickness of a thin walled material or the flaw detection of said material, by discharging a first capacitor in such a state that a switching element was brought to a continuity state after the first capacitor was charged and outputting a high frequency pulse current to the secondary side of a saturable transformer by the series resonance due to a second capacitor and a transmitting-receiving coil. CONSTITUTION:The output current of a high voltage generation circuit 601 flows to the primary side of a saturable transformer 600 through a resistor 602, a coil 604 and a capacitor 605 to charge the capacitor 605. Thereafter, when a thyristor 603 is turned ON in certain timing, the charge, which was charged to the capacitor 605, is discharged as a current I1 and this current I1 comes to zero after several musec because of the discharge through the coil 604. At this time, the transformer 606 generates an output current I2 in the secondary side of the transformer 606 and a capacitor 607 is charged and, when the transformer 606 is saturated after the elapse of about 1musec, the inductance of secondary side winding comes to almost zero and a high frequency pulse current I2 is outputted to the secondary side of the transformer 606 by the series resonance due to the capacitor 607 and the transmitting-receiving coil 4.
