Title: Auto-focus device for video camera
Inventor: HANMA KENTARO
IPC: H04N5/232
Filed: 1988-10-07
Abstract: PURPOSE:To realize the automatic focusing of both a usual distance range and a macro-area by changing the moving range of a master lens position. CONSTITUTION:An object image made incident on a zoom lens 1 is turned into an image picked-up video signal by a camera circuit 2, and is inputted to a focal quantity detection circuit 3, and the high band frequency component quantity corresponding to the sharpness of a picture contour is inputted to a difference detection circuit 4 at the period of one picture frame. Accordingly, a motor drive circuit 5 moves the focusing structure of the lens 1 by a motor 6. As for the output of the circuit 4, in the case of a state that the rotating direction of the motor 6 is to bring into focus, positive voltage output is obtained, and in the case of a contrary state, negative output is obtained, and by changing the rotating direction of the motor 6 forward and backward, auto- focusing operation is performed. In the case of infinity  distance, the position of the lens 1 is fixed, and in the case of other distance, the position of the lens 1 is changed accompanied with the change of magnification. In the case of the macro-area too, macro-operation is possible whatever the value of focal length is. Thus, the automatic focusing of both the usual distance range and the macro-area becomes possible.

Title: Distance measuring apparatus for vehicle
Inventor: MIMURO TETSUSHI
IPC: G01C3/06
Filed: 1994-10-18
Abstract: PURPOSE: To prevent the delay of reaction of a distance measuring sensor even when the surrounding part of a vehicle is dark and to improve the measuring accuracy by projecting the auxiliary light having a lateral fringe pattern when the surrounding part of the vehicle is judged to be dark. CONSTITUTION: Sensors S1 and S2 are constituted of a pair of lenses 5 and 6 and two sets of photosensor arrays 3 and 4. The lenses 5 and 6 condense the reflected light from an object (other vehicle) 2, project the object images on the arrays 3 and 4 and output the sensor signals on the basis of the object images on a sensor-output control circuit 7. The circuit 7 measures the distance to the object 2 and outputs the distance to a distanced determining circuit 8. The circuit 8 extracts and determines, e.g. the shortest-distance information among a plurality of the distance information, which is inputted on the basis of the specified algorithm, and outputs the information to a running-vehicle control circuit 9. The circuit 9 lights an auxiliary light unit 13 when it is judged that the surrounding part of the vehicle is dark.  Since the auxiliary light has the lateral fringe pattern, the fringes in the lateral direction, which are originally present in the object 2, become easy to observe, and the distance accuracy is improved.

IPC: F26B25/22
Filed: 1988-10-06
Abstract: PURPOSE:To prevent the generation of cracking of shell as well as the deterioration in the quality and taste of the same by a method wherein the temperature of hot air drying is controlled so as to be switched to a lower temperature based on the drying conditions of the amount of drying grain, an atmospheric temperature and the like. CONSTITUTION:Grain, flowing down through a drying chamber, is exposed to hot air heated by a burner 1 and is dried. When the temperature of the grain under drying is increased to a temperature higher than a predetermined value, a hot air drying is controlled so as to be stopped and is switched to ventilation drying to be effected by ventilating atmosphere. When the temperature of the grain is lowered by the ventilation drying to a predetermined temperature, the ventilation drying is switched again to the hot air drying mode while the hot air drying and the ventilation drying are repeated alternately whereby the grain is dried. Under a condition that the amount of grain to be dried is small or the temperature of atmosphere is high upon effecting the repeated drying by hot air heated by the burner 1, the temperature of hot air is switched into a low temperature and the grain is dried again by the hot air from the burner 1, which is provided with a temperature lower than a temperature before effecting the repeated hot air drying.
