Filed: 1990-01-29
Abstract: PURPOSE:To improve the image quality by coupling a detecting lens for forming an image in a position on the extension line of a recorded face by a scanning beam passing through the outside of view angle of an image forming lens in the outside of image range of a scanning start side, and a synchronization detecting element positioned on its optical axis. CONSTITUTION:With respect to a synchronization detecting element 9 provided on the scanning line by a rotary polygon mirror 3 and in a synchronous position of the outside of an image range on the extension line of the recorded face 4, a detecting image forming lens 12 provided separately is combined instead of an ftheta lens 5. The lens 12 allows a scanning beam passing through the outside of a view angle of the ftheta lens 5 to form an image as a minute spot in the synchronization detecting element 9, and the synchronization detecting element 9 is placed so as to be positioned on the optical axis of the detecting image forming lens 12. According to this synchronizing system, a scanning beam for synchronization which is made incident on the synchronization detecting element 9 passes through the optical axis of the detecting image forming element 12, therefore, even if a fluctuation is generated in the oscillation wavelength of a semiconductor laser 1, no shift is generated in the scanning position on the synchronization detecting element 9. Accordingly, the synchronization detection is always executed in the position of a deflection angle theta0 even if a wavelength fluctuation is generated.

Title: Detector for sudden crawler slip or bulldozer
Inventor: TAKASUGI SHINJI
IPC: B60W10/11
Filed: 1988-01-29
Abstract: PURPOSE:To automatically control the output and the speed by subtracting the crawler acceleration calculated by a crawler speed measured value from the measured acceleration in the longitudinal direction of a bulldozer to obtain a slip acceleration and outputting a slip signal. CONSTITUTION:A vehicle body acceleration alpha1 of a bulldozer 20 is obtained by a longitudinal-direction acceleration sensor 13. A change gear speed stage (m) and a torque converter output rotational frequency N are detected by a detector 15 and a detecting sensor 16, and a crawler speed V and a crawler acceleration alphaR are calculated by a differentiation circuit 11. A slip acceleration alphaS is obtained by a subtracting circuit 12 in accordance with alphaS=alpha1-alphaR. The acceleration alphaS is compared with a reference value alphaSTD by a slip decision circuit, and a slip signal S is outputted in case of alphaS<0.1G. Thus, the engine output and the change gear speed are controlled. Accelerations alphaR and alphaS are allowed to pass an LPF and an HPF, and thereby, influences of noise upon them are eliminated.
