Title: Traveling controller for beam-light-guided working vehicle
Inventor: YOSHIKAWA KOJI
IPC: A01B69/00
Filed: 1992-11-06
Abstract: PURPOSE:To exactly judge whether the cause of the non-light reception of an optical sensor for a steering control is due to the deviation of a body side control position, or due to the abnormality of a guidance beam light so as to execute an appropriate processing by stopping a steering control based on the received information of the optical sensor in the case of the abnormality based on the information of a working vehicle side communicating means. CONSTITUTION:When the light output of a guiding beam light projecting means B1 is not present, a ground side communicating means 27 transmits the abnormality information to a working vehicle V. And also, even when an object interrupting the optical path of a guiding beam light A1, that is, an optical path interrupting object is present, the ground side communicating means 27 transmits the abnormality information to the working vehicle V. The working vehicle V stops the steering control based on the received information of an optical sensor 17 for the steering control in the case of the abnormality, based on the information from a working vehicle side communicating means 19. Thus, when the guiding beam light A1 is not received by the optical sensor 17 for the steering control, it is possible to judge whether the cause is due to the deviation of the body of the working vehicle V, or due to the abnormal projection, and to erase the unnecessary steering control.

IPC: G06T7/60
Filed: 1990-11-05
Abstract: PURPOSE:To obtain a stable and highly accurate processing result from an optional input image by using a fractal dimension as a reference feature value and adaptively changing the size of a block in accordance with the variation of the fractal dimension. CONSTITUTION:This image processor is provided with a 4X4 block area extracting part 31, a 16X16 block area extracting part 33, a block area setting part 35, the 1st fractal dimension calculating part 41, and the 2nd fractal dimension calculating part 42. Adaptive algorithm for calculating a fractal dimension based upon a fixed block, allocating a block again based upon the change rate of the fractal dimension and calculating the fractal dimension again is adopted. Consequently, a block of a large size is allocated to an area in which the change rate of the fractal dimension is small, the generation of misrecognition due to fine variation can be reduced and its processing speed can be improved. On the other hand, a block of a small size is allocated to a small change rate area of the fractal dimension, so that the boundary between the two areas can be highly accurately discriminated.

Title: Drive power supply circuit of ink jet head
Inventor: HIWADA SHIYUUHEI
IPC: B41J2/05
Filed: 1994-12-02
Abstract: PURPOSE: To prevent the overvoltage output of the output voltage of a drive power supply circuit. CONSTITUTION: When a voltage setting circuit 2 is not normally connected and a resistor 1 is disconnected, output voltage Vout rises to reach the voltage turning a Zener diode 15 ON. When the Zener diode 15 is turned ON, the output voltage Vout does not become the voltage at the point of time when the Zener diode is turned ON or more. The output voltage at that time becomes Vout= Vref (reference power source voltage) + Vz (Zener voltage). That is, the output voltage of a drive power supply circuit reaches the highest voltage of the formula.  If the sum of the Zener voltage Vz and the reference power supply voltage Vref is matched with the max. rated voltage of a head driving circuit or the head or less, the drive power supply circuit does not output overvoltage exceeding the max. rated voltage of the head driving circuit or the head to prevent the destruction of the head driving circuit or the head.
