Title: Obstacle detector for unmanned vehicle
Inventor: OBARA MUTSUO
IPC: G05D1/02
Filed: 1993-06-14
Abstract: PURPOSE:To make it possible to operate an unmanned vehicle smoothly by sending wind toward a body to be detected, judging whether the body is swayed or not, and identifying whether the body existing around the unmanned vehicle obstructs the running or not. CONSTITUTION:A wind blowing part 7 generates the wind intermittently when a wind-blowing command is inputted from a main control part 11 and blows the wind (pulsating wind) toward a body from a nozzle. The wind blowing part 7 stops the generation of the wind when a wind-blow stopping command is inputted from the main control part 11. The atittude of a video camera part 8 is controlled together with the wind blowing part 7 by an attitude control part 9 through a universal head 12. The image of the body to be detected before and after the blowing of the wind from the wind blowing part 7 is photographed. Then, the original image data before and after the wind blowing are outputted into an image processing part 10. Whether the body is the obstacle for the running of an unmanned vehicle or not is detected on the basis of whether the body is swayed with the wind blowing or not. Therefore, the state outside of the unmanned vehicle can be accurately obtained.

Title: Displaying method of run distance
Inventor: YAGI SOUICHI
IPC: G01C22/00
Filed: 1983-09-13
Abstract: PURPOSE:To display run distance and trip data by sectionalizing EEPROM as a counting part and thus providing plural storage areas. CONSTITUTION:The EEPROM30 is provided with plural count data storage areas and trip data storage area. The data storage areas are so provided that the maximum number of count digits is divided and the areas are dispersed on one- count-digit unit basis for the least significant digit section, i.e. to many areas. Consequently, the final data is displayed as run distance on a display 61. Further, the point which deviates negatively from a zero point by the counting data of the least significant digit section is set as an origin in a trip start so as to display the trip data, and corresponding count data is added every time when a carry to a higher-order digit section is made. Consequently, the obtained trip data is displayed on a display 62. Thus, the run distance and trip data are displayed.

Filed: 1985-07-31
Abstract: PURPOSE:To prevent the damage of magnetic recording information by providing a notch part to which the outer ring of a bearing is fitted at a part of a guide rail and moving and locking the actuator to the fitting position when a magnetic disk device is not operated to automatically lock an actuator. CONSTITUTION:When the magnetic disk device is operated, an actuator 13 is movable freely in arrow head direction 12, and a magnetic head 2 is moved and positioned by a driving means 11 in the 12 direction. At a pre-load guide rail 9b, a notch 10 is provided and it is constituted that a pre-load bearing 7b is not arrived at the position of the notch 10 within the driving range of the actuator 13 in a normal operation. However, when the terminating signal of the magnetic disk device is issued and the control part of the driving means 11 detects it, the driving means 11 moves the actuator 13 to the position where the pre-load bearing 7b is fitted to the notch 10 and locks it. Therefore, a damage due to friction between the magnetic head 2 and the magnetic disk 1 generated by vibration in transportation can be prevented.

Title: Character recognition device
Inventor: MIYAMAE TORU
IPC: G06K9/46
Filed: 1993-07-07
Abstract: PURPOSE:To provide a character recognition device which can obtain the highly accurate and stable recognition performance even for a character pattern of low quality that has the local variation of line width. CONSTITUTION:Four types of subpatterns are extracted at every scanning direction based on the average line width of an original character pattern. Furthermore a blurred pattern is extracted. If it is decided that a restoration pattern must be generated for the remaining pattern obtained by excluding the infinitesimal segments form the blurred pattern, a blur restoration pattern is generated by a thickening processing. In the same way, the sub-pattern of the blur restoration pattern are extracted at every direction. Then an area included in a circumscribed frame of the original character pattern or a synthetic pattern of the original character pattern with the blur restoration pattern is divided into the lattice-shaped partial areas. Then the feature value is calculated in each divided in each divided area of either a subpattern or a synthetic subpattern of the subpattern with the blur restoration pattern. Thus a feature matrix is generated and collated with the feature matrix of a dictionary 137. Thus the characters are recognized.
