摘要： PURPOSE:To shorten the time required to calculate the position and attitude of a commander plane by performing specific extrapolation processing for a program for calculating the position and attitude of the commander plane. CONSTITUTION:A block 141 solve the fine turbulent motion equation of a stable coordinate system to obtain xa and omega as results. Then a block 142 integrates them to obtain xa and omega as results. A trailing block 143 performs conversion to an inertia coordinate system for the xa according to an attitude matrix to obtain xe as its result. Then a following block 144 calculates the position and attitude according to the xe and omega to obtain xe and L as results, which are applied to the simulation visual field display device of a block 145. Consequently, the time required for the calculation is shortened.

摘要： PURPOSE:To obtain a device with excellent environment resisting performance by using a vertically symmetrical fiber bobbin pertaining to a mounting section with a gyrobase so that two points of an optical fiber are positioned in a vertical symmetry on the same layer at an equal distance from a midpoint. CONSTITUTION:A fiber bobbin 1 is formed in a vertical symmetry pertaining to a mounting section 2 with a gyrobase. Therefore, an optical fiber can be wound to ensure that two points thereof are positioned in a vertical symmetry on the same radius at an equal distance from the midpoint 3c thereof or that they are in the same direction in a fiber loop as a whole. With such an arrangement, for example, heat flowing in from outside a gyroscope is transmitted in a vertical symmetry to the fiber loop through a heat bridge 2. Thus, a rate of change in temperature at two points at an equal distance from the midpoint 3c of the optical fiber always gives an equal value, thereby reducing a phase difference to zero by canceling.

摘要： PURPOSE:To hold a saturated voltage at a fixed value by providing a limiter circuit with three operational amplifiers, connecting power sources for regulating upper limit and lower limit saturated voltages to the positive input sides of respective operational amplifiers, connecting the output voltages to diodes and connecting the output terminal of an arithmetic circuit to the negative output sides of respective operational amplifiers. CONSTITUTION:The limiter circuit is provided with an operational amplifiler A2 for obtaining an upper limit saturated voltage and an operational amplifier A3 for obtaining a lower limit saturated voltage in addition to an operational amplifier A1. An upper limit voltage V1 is connected to the positive input side of the amplifier A2, the output of the amplifier A2 is connected to the cathode of a diode D1, a lower limit voltage -2V is connected to the positive input side of the amplifier A3, and the output of the amplifier A3 is connected to the anode of a diode D2. In addition, the negative inputs of the amplifiers A2, A3 are connected to the output terminal of the arithmetic circuit. Since the power sources V1, -V2 are connected to the positive input sides of the operational amplifiers, current does not almost flow, and even when the internal impedance of the power supplies is high, a saturated output voltage E0 can be held at a value almost equal to the V1 or -V2.

摘要： PURPOSE: To conduct training safely by controlling the motion of a reduced model corresponding to crane manipulating operation so that a visual object is seen moving at its actual speed. CONSTITUTION: This simulator is provided with a simulation operation room 10 installed below the substrate 51 of a chassis 50 and the reduced model 20 for the container suspension mechanism of a container crane suspended from the substrate 51. All models 20, 32, 34, and 35 are equal or nearly equal in reduction ratio, and also arranged so that the distance to the eye of a crane operator in the operation room is a reduction ratio multiple of the actual distance; and the movements of the respective models 20, 32, 34, and 35 are brought under servocontrol so that the speeds of the relative movements between the operation room and respective models corresponding to the crane manipulating operation of the operator are reduction ratio multiples of the actual speed. Therefore, the same visual information with the actual crane operation can be given to the operator. Consequently, this simulator is usable for the training of all operations from the suspension to the unloading of a load in the same presence with actual crane operation.

摘要： PURPOSE:To make the calculation and the control of every kind concerning to a segment every poligon unnecessary by giving an object number deciding the priority order of disappearance relation in the mutual objective substances and obtaining the needed edge data of the polygon complying with the substance. CONSTITUTION:The object number expressing the priority order of the disappearance relation in the mutual substances of the plural objects is decided, the edge data on the display screen of the substance is obtained and the parameter of every kind concerning to the intersection point of the edge and a scanning line on the display screen is calculated based on the edge data. Then the intersection points are rearranged along the scanning line and the rate of change of lightness and depth are obtained in the prescribed direction of the polygon constituting the substance. After deciding the visible part of the objective substance, the misty state in the visible part is adjusted. Thus the visible part of the objective segment can be easily decided without calculating and comparing the depth of the segment or dividing the scanning line.

摘要： PURPOSE:To obtain a mechanism which adjusts mistuning torque and gimbals unbalance torque by providing four adjusting screws on a gimbals and moving and adjusting them to the gimbals. CONSTITUTION:This gyro has a flexture higher hinge mechanism 12 and a gyro rotor 10 supported at its periphery. Then the mechanism 12 is so constituted that an inner flexture hinger hinge 30 and an outer flexture hinger hinge 32 are coupled through the gimbals 34. Screw holes 40 are formed in this gimbals 34 at constant intervals and four adjusting screws 42 are engaged threadably with those holes. Then two or four screws 42 are lifted up or down in the same direction by the same quantity to adjust the gimbals unbalance torque. Then a couple of opposite screws 42 are lifted in the same direction by the same quantity and the the other two screws are moved in the opposite directions by the same quantity to adjust the mistuning torque.

摘要： PURPOSE: To reduce the weight by provide a concave mirror consisting of a laminated structural body which is formed by using a fiber reinforced plastic material as a reinforcing material and has a reflection surface on a concave surface. CONSTITUTION: The concave mirror 3 is constituted by laminating a glass sheet 5 on the concave surface of the sheet 4 of the carbon fiber reinforced plastic material formed to a spherical shape and depositing aluminum and silicon oxide protective coating by evaporation on the surface of the glass sheet 5 to form the reflection surface. This concave mirror 3 is used by installing the mirror on the front surface of an image generating means in combination with a beam splitter. While the concave mirror 3 having the laminated structure is provided with high rigidity in such a manner, the thickness thereof is reduced to reduce its weight. As a result, the weight of the image display device is reduced.
