Title: Linkage supporting structure of operational lever
Inventor: AIHARA MASAHIKO
IPC: B62M25/04
Filed: 1991-10-03
Abstract: PURPOSE:To provide a linkage supporting structure of an operational lever for reducing a frictional force worked on the operational lever, and for rotating the operational lever smoothly thereby. CONSTITUTION:The end part of a clutch lever (operational lever) 5 is linked and is supported by a bolt (axis) 6 crossing the rotational flat surface of the clutch lever 5 so that the clutch lever can be freely rotated. A needle bearing 7 is provided between the outer periphery of the bolt 6 and the clutch lever 5, and the upper and lower surfaces of the needle bearing 7 are sealed by an O-ring 9. Since the clutch lever 5 is linked through the needle bearing 7 provided on the outer periphery of the bolt 6, by which the lever is pivotally mounted so that the lever can be freely rotated, even when a force F perpendicular to the bolt 6 works on the clutch lever 5, the clutch lever 5 will be smoothly rotated without obstruction around the bolt 6 through the work of the needle bearing 7. Intrusion of foreign object such as dust into the needle bearing 7 is inhibited by the O-ring 9, while loosening of the clutch lever 5 is prevented.

IPC: G06K9/00
Filed: 1990-10-20
Abstract: PURPOSE:To convert both a character and a ruled mark to character codes by recognizing the character from an area from which the ruled mark is eliminated, and outputting image information by adding the coordinate of an extracted ruled mark. CONSTITUTION:Firstly, ruled mark extraction is performed by a ruled mark extraction means 1. The ruled mark extraction is performed by using a personal computer 11 in the range of an original image equivalent to the range designated on an image by an operator, and the coordinates of vertical and lateral ruled marks on the original image are stored. Thence, inclination in a row direction is calculated from the coordinates, and a read image is stored in image memory 10-4 to 10-6, and recognition processing is performed at a recognition processing part 10-3. A character recognition means 2 recognizes the character from the area from which the ruled mark is eliminated. The recognition of the character is performed by judging the area of each row in unit of row, and the area of the row is found corresponding to the inclination in the ruled mark extraction, and the character on the row is recognized. A recognition result output means 3 outputs the character code including a ruled mark code from the results of those extraction means 1 and recognition means 2.

Title: Cowling device for motorcycle
Inventor: YAMAMOTO ATSUO
IPC: B62J33/00
Filed: 1988-11-11
Abstract: PURPOSE:To enable the reduction in the thermal influence that the high-temperature engine cooling air affects the legs of an operator by directly introducing the cool running wind flowed in from the front through an intake port to the front of the operator's legs through an air-passing passage, during running. CONSTITUTION:Since forwardly opened outside-air intake ports 22 are opened in an under cowling 14 on the right and left both sides of an air introducing port 16, cool running wind from the front flows into the air-passing passages 24 inside the under cowling 14, during running. The discharge port 23 at the end of this air-passing passage 24 is opened directly before the leg part B independently of a cooling air passage 17 in such a condition as the communicating port 26 is closed; therefore, the cool running wind is directly introduced toward the operator's leg part B through the discharge port 23, and directly before the leg part B, the high-temperature cooling air from the cooling air passage 17 is mixed with the cool running wind. Thus, since the temperature of cooling air flowing toward the leg part B is lowered, the thermal influence of cooling air to the leg part B can be restrained to a lower degree, and even in the summer season when the outside air temperature is high, a comfortable drive can be continued.

Title: Vehicle collision preventing sensor
Inventor: MIZUNO HIROSHI
IPC: G01B11/00
Filed: 1992-10-22
Abstract: PURPOSE:To inform an operator in detail of a vehicle position when a vehicle is parked into a garage by arranging a sensor in a garage building to detect a distance between the sensor and the vehicle, and operating a warning device for collision prevention, etc., when the distance is too small. CONSTITUTION:A light beam emitted from a light emitting element 1 is reflected on a vehicle 3 through a lens, and made incident on a PSD5 through the lens. The position where the light beam enters the PSD5 varies depending on a distance between the vehicle 3 and a sensor. When the vehicle 3 is separated further from the sensor, the reflected light beam varies according to the distance, and the spot position of the light beam incident on the PSD5 also varies. As the spot position of the light beam made incident on the PSD5 varies, a balance between signal currents I1 and I2 taken out from both ends of the PSD5 varies. By detecting the balance of the signal currents I1 and I2 by a signal processing circuit 8, a distance between the vehicle and the sensor is detected and, when the distance is too small, an alarm signal is transmitted to an external warning device, external warning light, etc., for collision prevention.
