Title: Trouble detecting device for wheel speed sensor signal system
Inventor: MATSUMURA SHIGEKI
IPC: B60T8/88
Filed: 1994-07-15
Abstract: PURPOSE:To detect the wire breakage and the grounding trouble by installing a logic sum means for generating the logic sum between the detection of the electric potential of the signal line lower than a standard electric potential by a voltage comparing means and the detection of the state where electric current does not flow in an element by an electric current detecting means. CONSTITUTION:When a wire breakage trouble is generated on a grounding wire 3c, the reversal input of a calculation amplifier 11a becomes high, and the base input of a transistor Tr2 becomes the zero electric potential. Accordingly, the output of the calculation amplifier 11a lowers, and the output of the transistor Tr2 becomes high. Accordingly, the output of an OR circuit 11b becomes high level Hi. When a ground fault is generated on the grounding wire 3, the base input of the transistor Tr2 becomes zero electric potential. Accordingly, the output of the transistor Tr2 becomes high, and the output of the OR circuit 11n becomes high level Hi independently of the state of the calculation amplifier 11a.

Filed: 1992-05-29
Abstract: PURPOSE:To make the shape of a beam spot, with which an optical disk is irradiated, into an almost true circle even when the deflection angle width of light beams is set large. CONSTITUTION:The long diameter direction of light emitted from a semiconductor laser 9 in the pattern of a long circle is directed toward the inclining direction (a direction B) of an emitting plane 2a of a light deflecting element 1. When the laser beam emitted from the semiconductor laser 9 passes through a 1/2 wavelength board 16, the polarizing direction of the laser beam is rotated at 90 deg., and this polarizing direction is made parallel to the direction B. Since an acoustic wave advancing direction H due to an acoustic wave exciting means 20 is made parallel to the polarizing direction at the light deflecting means 1, the laser beam is excited by the acoustic wave exciting means 20, and the laser beam emitted from the inclined emitting plane 2a is largely excited. The long diameter direction of the laser beam emitted from the semiconductor laser 9 is reduced by the inclined emitting plane 2a, made into the almost true circle and converged on an optical disk 11.
