Title: Detecting method for vehicle body
Inventor: YAMAMOTO SHIGEHIRO
IPC: G05D1/02
Filed: 1988-09-17
Abstract: PURPOSE:To avoid the increase of the position error of a vehicle body by correcting the constant related to the wheel diameter based on the difference and the ratio between the directional change value calculated from the rolling distance of the right and left wheels for measurement and the value calculated from the directional value of the vehicle body at a point of correction. CONSTITUTION:A camera 5 detects a mark 6 at the n-th point of correction and obtains the encoder pulse number integration amount detection values PL<n> and PR<n> of the left and right wheels for measurement with the vehicle body direction set at THETA<n>. In the same way, the detection values PL<n+1> and PR<n+1> are obtained at the (n+1)-th point of correction with the vehicle body direction set at THETA<n+1> respectively. In this case, the arithmetic value theta<n+1> is obtained and therefore an error thetad=THETA<n+1>-theta<n+1> is produced. The change value DELTAD is calculated as prescribed for the constant related to the diameters of both wheels that causes the error thetad and the constants DL and DR are corrected. Then a ratio thetar is calculated as prescribed between the arithmetic value thetaand the vehicle direction correction value THETA at the next point of correction. Then the constants DL and DR are corrected and the corrections with use of the error thetad and the ratio thetar are alternately repeated. Thus both constants DL and DR are automatically rationalized and the position error of the vehicle body is never increased up to the next point of correction.

Abstract: PURPOSE:To facilitate packaging of an automatic focusing mechanism and to reduce size and weight by disposing linear image sensors for automatic focusing on the same semiconductor chip as the semiconductor chip of an area image sensor for photographing, refracting the light from a subject past a photographing lens and guiding the same to the linear image sensors. CONSTITUTION:The light from the subject past the photographing lens 10 is refracted by an optical refracting means and is guided to the linear image sensors 16, 18 for automatic focusing on the same semiconductor chip 20 as for the area image sensor. An optical path is so selected that the two linear image sensors 16, 18 exist respectively before and behind the focal position in the case of automatic focusing by a contrast method.

Abstract: PURPOSE:To adjust the interval between a magnetized part and a rotation detecting pattern quickly with high accuracy and to facilitate fixing work of a rotary shaft based on the adjustment by making a through-hole through the rotation detecting pattern made oppositely to the magnetized part on the periph eral edge of a rotor. CONSTITUTION:When a rotary shaft 19 is moved in thrust direction, a rotor 13 also moves to cause movement of a magnetized part 21 thus permitting adjustment of a gap t with respect to a pattern 26. A gap measuring sensor is then inserted into a through-hole 30 and the rotary shaft 19 is inserted into a housing 23 with the gap t between the magnetized part 21 and a rotation detecting pattern 28 being measured. Insertion of the rotary shaft 19 is interrupted when the gap t reaches a preset value. Upper end 23a of the housing 23 is caulked under that state thus securing the rotary shaft 19. According to the system, the gap can be measured directly and adjusted accurately and easily. Furthermore, since the position is fixed after adjustment through caulking, the work is facilitated remarkably and the efficiency of adjusting work can be improved.
