The detector 2 and decision device 9 are used to automatically find a point D on a track where the straight line connecting the earth center and satellite and the sun direction intersecting orthogonally with each other. The output of the detector 1 at the point matches the attitude angle around the X axis, which is utilized to enable an inexpensive device to be used and also find the attitude angles by simple algorithm. Further, the automatic constant setter 30 converges a large initial estimation error to zero speedily by varying the constants of a constant associative integrator 11 and a constant multiplier 12 automatically and has excellent estimation accuracy which is hardly affected by the output noises of the angle detector after the convergence.

IPC: B60G17/015
Filed: 1988-12-15
Abstract: PURPOSE:To prevent a squat phenomenon by controlling the actuator control valves of the front wheels and the rear wheels depending on the signal of a car starting detecting device to make the car height at the rear wheel side higher than that at the front wheel side. CONSTITUTION:The differential value of the output value of a suspension stroke sensor 1 by a differential circuit 3 and the integral value of the difference between the output value and the object value by an integral circuit 4 are processed in an adder circuit 5 to output a control signal. In this case, depending on the acceleration in the advancing direction of the car detected by a G sensor 6, a main control device 2a detects the car starting, and a control pattern responding to the starting is selected. When the acceleration at the starting is in the medium or the high G area, the posture is controlled to make the object car height value at the front wheel side reduced lower than the standard car height, while the car height at the rear wheel side increased higher than the car height of the front wheel side. By such a constitution, a squat phenomenon can be suppressed.

Abstract: PURPOSE:To reduce the cost and to obtain the tape player capable of making a tape hardly accept damage even on its edge by providing a tape guide equipped with a flange part for regulating the widthwise position of the tape wound around a head drum to a sliding body to fix its positional relationship with the head drum. CONSTITUTION:The tape guides 72 equipped with the flange parts 72a and 72b positioned on both side parts of the head drum 23 for the purpose of regulating the widthwise position of the tape wound around it are provided to the sliding body 52 in order to fix its positional relationship with the head drum. Consequently, it is not necessary to provide the head drum 23 with a lead, and hence the cost of processing the head drum 23 is remarkably reduced, so that reduction of the cost for the tape player can be contrived. Then, because of no sliding of the tape on its side edge with a lead which is to be in existence over a long distance, there is an advantage of hardly receiving damage to the tape even on its edge. By this method, the tape player can be manufactured at low cost, and the tape player can be obtained to be afresh and capable of correctly regulating the position of the tape against the head drum.

Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of noises by adding a diversity power switch means which supplies the power to a diversity circuit only when the output images of a TV device are selected by a monitor mode control means. SOLUTION: A relay 86R is added to the supply line of a diversity power supply 86P, and the on/off of the relay 86R is controlled by a diversity power switch means 85 and interlocks to a changeover switch 89 of a radio shared antenna 88R. The relay 86R is turned on only when the switch 89 is switched toward a diversity circuit 86 and then turned off otherwise, i.e., when a TV device is turned off. As a result, the noises caused by the fast switching operations never flow into a room from a radio device 72R even when the device 72R is turned on since the power is cut to the circuit 86. Furthermore, the supply 86P is kept in an OFF state to the circuit 86 as long as the circuit 86 needs no power and accordingly the power consumption is reduced.
