Title: Method for detecting acceleration of vehicle
Inventor: TAKAHASHI YOSHIO
IPC: G01P15/18
Filed: 1985-07-30
Abstract: PURPOSE:To accurately detect the acceleratiopn of a vehicle irrespectively of the gravitational acceleration, by calculating the acceleration of the vehicle from the 1st acceleration information related to the front-rear direction of the vehicle and 2nd acceleration information related to the top-bottom direction of the vehicle. CONSTITUTION:The acceleration information VA2 detected by means of an accelerometer A is composed of a component VA1 depending upon the run of a vehicle and another component V'A1 produced when the acceleromater A is inclined. In the case of, for example, a plumb type acclerometer, the V'A1 becomes as follows: V'A1=komegasintheta, where, theta is the grade of a slope, k is a proportional constant, and omega is the weight of the plumb. Therefore, the vA2 becomes as follows: vA2=vA1+komegasintheta. Wheh another acceleromater B is taken into consideration, sintheta=vB2/vB1 is found by comparing the output vB1 at the time of running flatland and the output vB2 at the time of running a slope. Accordingly, the acceleration vA1 (vA1=vA2-lomegavB2/vB1) produced in relation with the run of the vehicle is found from the above-mentioned formulae.

Title: Disk driving device
Inventor: TANAKA SHINSAKU
IPC: G11B17/04
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To perform the centering of a disk whose dimension is out of specifications with high accuracy and to prevent the surface wobbling of the disk with thin and simple constitution by performing the centering of the disk while pressing the disk with elastic pressing parts and also while pressing the tapered surface of a clamper against the peripheral part of the center hole of the disk. SOLUTION: The protrusion 19 of a clamper 3 is pushed by the pressuring part 21 of an elevating and lowering mechanism 20 and the centering of a disk 1 is performed by making the lower surface of the disk 1 to be closely adhered to a disk mounting surface 7 with a tapered surface 15 while bending three elastic pressing parts 14. At this time, since axial lines of a turntable 2 and the clamper 3 are made to coincide by the engagement of cylindrical surfaces 16, 8 and axial lines of the disk 1 and the clamper 3 are made to coincide by pressing the peripheral part of the center hole of the disk 1 with the tapered surface 15, the turntable 2, the clamper 3 and the disk 1 can be highly accurately centered.  Thus, even when the disk 1 is rotated at high speed by rotatingly driving the turntable 2 with a motor 10, the surface wobbling of the disk is never generated because the disk 1 is pressed with elastice forces of the elastic pressing parts 14.
