| PURPOSE:To obtain a rotation angle speed detector having less power consumption by using an electronic heating and cooling element as an element for speed regulation. CONSTITUTION:One part of thermal exchanging base plates of an electronic heating and cooling elements 5a, 5b is brought into contact with a gas 6 of the inside of a case 1 and the other part is brought into contact with fins 7a, 7b.

The elements 5a, 5b are available for both heating and cooling and by setting the temp. of the inside of the case 1 to the temp. nearly around the case 1, the temp. difference to be adjusted by the elements 5a, 5b becomes smaller and the loss of the necessary thermal energy for keeping the temp. is reduced. The reduction in power consumption and the shortening of starting time are therefore enabled. | ||||||

| PURPOSE:To facilitate the regulation of the amplification factor by a method wherein a rate sensor is rotated by a specified angle and the amplification factor of an amplifier is automatically regulated according to the deviation calculated between the angle of rotation of the rate sensor and the actual angle of rotation with the integration of an amplified angular velocity signal. CONSTITUTION:An angular velocity detection signal 100 of a rate sensor 10 is fed to an amplifier 12 made up centering around an operational amplifier and amplified with the amplification factor adjustable. The amplified angular velocity detection signal 102 of the amplifier 12 is fed to a computing circuit 16 through an A/D converter 14. The computing circuit 16 integrates the amplified angular velocity detection signal 102 and vehicle speed to calculate the relative bearing and running range of a vehicle. Based on the results, the present bearing and position of the vehicle are determined from moment to moment and the running path of the vehicle, the distance to the destination, direction and the like are shown on a CRT unit 20. The computing circuit 16 also feeds a amplification factor control signal 108 to the amplifier 12 to automatically adjust and set the amplification automatically. | ||||||

| PURPOSE:To measure angular velocity correctly employing an A/D converter with a relatively small conversion range by a method wherein a difference is obtained between the output of an auxiliary D/A converter and the output of an angular speed sensor and the difference output is converted into a digital signal with an A/D converter to be fed to an arithmetic processing section. CONSTITUTION:The output of an angular velocity sensor 11 is converted into a digital signal with an A/D converter 12 and fed to an arithmetic processing section 13. On the other hand, a vehicle speed sensor 14 detects the vehicle stopping and the detection output thereof is fed to the arithmetic processing section 13. In addition, an analog signal converted with an auxiliary D/A converter 15 is applied to an analog difference circuit 16 to obtain a difference from the output of the angular velocity sensor 11. Thus, the output of the angular velocity sensor is fed to the A/D converter after a value corresponding to the output at the zero point is subtracted with the auxiliary D/A converter thereby enabling the use of an inexpensive angular speed sensor with a large output at the zero point. | ||||||

| PURPOSE:To obtain a rate sensor with an excellent durability at a low cost by mounting a rotor on a casing as having an amply large inertial moment with respect to the friction torque of shaft support to detect relative angular velocity of rotation between the casing and a rotor. CONSTITUTION:As a stator 25 rotates or oscillates, a casing 12 moves. With relative rotation or oscillation of the casing 12 and the rotor 14, lights from light sources 18 and 19 are incident intermittently to light receiving sections 20 and 21 through a slit plate 17 and a pulse output is emitted to a detection circuit 22 at an interval according to the relative angular velocity. The detection circuit 22 computes the angular velocity based on the pulse interval. The rotation or oscillation direction of the stater 25 is judged depending on the output state of the light receiving section 21 at the rising of an output pulse of the light receiving section 20. As the rotor does not rotate at such a high speed as a gyroscope, wear of the bearing section can be reduced. | ||||||

| PURPOSE:To stabilize the oscillation frequency of a crystal oscillating element over a wide frequency range at low cost, by installing the crystal oscillating element for the resonance circuit of an oscillator in the constant temperature part of a thermostatic chamber for a gas rate sensor. CONSTITUTION:Gas is blown from a nozzle 7 at a peak part to two probes 6. The temperature difference between two probes 6 corresponding to the deflection angle of the gas flow due to the inertia of the gas is detected in the form of a difference in resistance value, so that temperature in the container 4 is an element which determines an azimuth angle detection error. Then, a gas rate sensor 5 is installed in the thermostatic chamber to constitute the gas rate gyro so that the container 4 is held at constant temperature, and then the container 4 is held at constant temperature during the operation of the gas rate gyro; the crystal oscillating element 1 is attached to the peak part, a one-side electrode is connected to the container 4 and grounded in common, and a lead wire 2 is connected to the crystal oscillator while piercing the seal 3, thus stabilizing the oscillation frequency of the crystal oscillating element 1. | ||||||

| PURPOSE:To eliminate drift of an offset voltage by forcibly turning the output voltage of an amplifier to a reference voltage in a cyclic manner. CONSTITUTION:When a positive voltage is outputted to an output terminal 12 of an amplifier 11 by a voltage at a terminal 7 of a bridge circuit, a voltage almost equal to that at the output terminal 12 is outputted to a terminal 17 with an emitter follower circuit 13 of a transistor. As a time, electronic switch 14 at Ta is ON, the voltage at the terminal 7 is raised while the voltage at an output terminal 10 of an amplifier 9 lowered so that the voltage at the output terminal 10 is maintained zero constantly. Then, the time, electronic switch 14 at Tb is turned OFF. As contacting a heat wires 1a and 1b unevenly due to an angular velocity, an inert gas cools heat wires 1a and 1b and a voltage nullifying the offset voltage is outputted to the terminal 10 in proportion to actual angular velocity. | ||||||

| PURPOSE:To enable the detection of an angular velocity generated in each of a plurality of planes by arranging at least two couples of thermosensitive elements in one sensor. CONSTITUTION:A sensor 8 for sensing a gas flow is provided at the position facing a nozzle hole 5a in a holder 7. The sensor 8 is made up of two couples of thermosensitive elements arrayed at a specified positions and intervals. In the normal case, the gas flow is injected from the nozzle 5a and passes through the center position corresponding to the axis part of an internal passage 15 leading to a through hole 7a. In an abnormal case where an angular velocity is applied to a gas rate sensor from outside, the gas flow in the internal passage 15 is diviated from the center position. This produces a fine difference in the output between the two couples of thermosensitive elements, which enables the detection of an angular velocity generated in the gas rate sensor. | ||||||

| PURPOSE:To improve the detection accuracy eliminating effect of disturbance due to vibration of a sensor body by inserting the body into a casing through a vibration proof material so that external vibration will be absorbed to prevent the vibration of the sensor body. CONSTITUTION:One side end plate 20 of a gas rate sensor 10 is inserted into a casing 91 through three sensor bushes 38, 48 and 58 while the other end 12 thereof is done so through a sensor bush 71 having threads 72 and 73. These sensor bushes 38, 48, 58 and 71 are each made of an elastic material such as rubber. Therefore, vibration transmitted to an internal casing 90 through an external casing is absorbed and damped by these sensor bushes 38, 48, 58 and 71 and hence fails to be tansmitted to the gas rate sensor 10. This eliminates effect of disturbance due to vibration to improve the detection accuracy. | ||||||
