Title: Gyroscope apparatus
Inventor: MASUZAWA ISAO
IPC: G01C19/56
Filed: 1989-06-08
Abstract: PURPOSE:To achieve a low cost, low power consumption, low heat generation and a compact size by providing a modulator which uses the output of a phase shifter as a reference signal in a control circuit. CONSTITUTION:The magnitude of the rate of the differential value of the vibrating amplitude of the mass part of a tuning fork is detected with an AC   DC converter part 16. The value is compared with a reference preset value V1 which is set with a setting element from a reference voltage V in an adder AD1. The result of the comparison is inputted into a deviation amplifier 18. A DC voltage Ve which is required for keeping the tuning fork at a constant rate is obtained in the deviation amplifier 18. The DC output Ve is converted into an AC control signal Vc at the same phase as that of the differential value of the vibration amplitude of the mass part of the tuning fork in a modulator 19. The signal Vc is outputted into a driving device 48 for the mass part of the tuning fork. Therefore, the phase condition of the self-oscillating system of the tuning fork is satisfied. The condition of a gain control system is made to function effectively. The differential value of the the vibra tion amplitude of the mass part of the tuning fork is stabilized and kept constant. Thus, the cost of the apparatus is made low, and low power consumption, low heat generation and the compact size can be achieved.

In the case, the flexible substrate 40 is formed so as to make a deformation center 41 to close to the rotation center of the hinge 31. Consequently, the flexible substrate 40 is deformed by following the opening/closing operation of the cover 20 so that the bending angle amount, the difference between the expanding/retracting and the moving amount of it becomes small.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of partial concentration of stresses in a joint part and increase the pressure-resistant capacity, by shifting the connection part of mutual external steel pipes from the connection part of mutual internal steel pipes in the axial direction by a certain distance and joining these pipes in the metal-touch connection. SOLUTION: A steel pipe concrete member 1 used for intermediate columns or the like on which an axial compression acts, is formed by placing concrete in the space F between the external steel pipe 2 and the internal steel pipe 3 at a construction site. The distance between the connection part of mutual external steel pipes 2 and the connection part of mutual internal steel pipes 3 is separated from each other by about two times the outer diameter of the inside steel pipe 3. Mutual pipes are not welded but joined in the metal-touch connection to transmit the axial force N and the bending moment M and further, transmit the shearing force Q by the external steel pipe 2 and the concrete 4.  The connection part is formed such a position that a transmission stress does not gets excessive, and the transmission of stress can be reinforced by arranging studs or steel frame pieces on the external peripheral face of the internal steel pipe 3 of the connection part or other means. In this way, partial concentration of stresses can be prevented and the pressure-resistant capacity of the member 1 can be increased.
