Abstract: PURPOSE:To cause quick response to the change in rotation and prevent the error of a ring laser unit, by straightly vibrating light detectors and Fresnel-effect-producing transparent members 15 the same phase as the displacement of an interference fringe. CONSTITUTION:A laser tube 4 is provided among reflectors 1, 2, 3 so that a ring laser unit is formed. Output beams 5, 6 are mixed with each other by a light mixer 7. An interference fringe is enlarged by a columnar lens 12. Light detectors 8, 9 and transparent members 13, 14 such as quartz, which act to produce a vibration bias by the Fresnel effect, are secured on a vibratory base 15. The direction and frequency of movement of the interference fringe are detected by the light detectors to generate a beat signal corresponding to the angular velocity and direction of rotation of the ring laser unit to straightly vibrate the base 15 at the same phase and amplitude as the movement of the interference fringe. This results in enabling quick response to the change in the rotation and the vibration of only a portion of small weight. Therefore, the error and fatigue of the ring laser unit can be provented.

Title: Helmet with device for detecting approach of obstacle
Inventor: TADANO HISASHI
IPC: B66F11/04
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To prevent such an accident that a worker collides against an obstacle in advance by judging that the obstacle approaches a predetermined scope by a proximity sensor after receiving a signal from the proximity sensor, outputting a judgement signal, and operating an alarm means based on the judgement signal. SOLUTION: When a worker wears a helmet and works at an elevated place, for example, ultrasonic waves generated by an ultrasonic sensor 11b are reflected by an obstacle to receive as reflected waves, and the ultrasonic sensor 11b generates AC voltages. A receiver 15b which receives the AC voltages confirms that they are reflected waves to send signals to a distance calculator 16b. The distance calculator 16b measures the time until the receiver 15b receives the waves to calculate a distance up to the obstacle as a voltage value. A comparator 17b judges whether the voltage value reaches a voltage value of the set distance or not by the comparison. In case of YES, a signal is output to an OR circuit 18, and, a judgement signal is output to a drive 19a by the OR circuit 18 to operate an alarm sound device 19b.

Title: Method and device for producing fiber from viscous substance
Inventor: IKEDA KAORU
IPC: D01D4/06
Filed: 1993-02-08
Abstract: PURPOSE:To produce fibers from a viscous substance by a spiral method reducing the content of shots. CONSTITUTION:The lowering flow 14 of a viscous substance simultaneously receives the actions of the plural flows of the first gas approaching a point P at a place near the point P at which the first gas flow 7 most nearly approaches the flow 14 of the substance, finely divided, uniformly distributed onto the periphery of a central axial line H0 along the respective travel directions of the first gas flows 7 gradually apart from the point P, further blown out toward the first gas flows 7, receiving the action of the second gas flow 12 whose cross section is gradually narrowed, and subsequently discharged in the form of the drawn fibers from the outlet of the cylindrical tube 8a of the second nozzle 8. When the throttle mechanism of the cylindrical tube part 8a is disposed and when the second gas flow 12 is progressed so as to wholly throttle into a conical shape toward the central axial line H0, shots in the fibers 16 are reduced, and the fibers are stably formed without thinning and shortening the fibers beyond necessary thickness and length.

Title: Method for processing inclined image
Inventor: TSUCHIYA KAZUHIRO
IPC: G06T7/00
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide an inclined image processing method capable of quickly processing an image read out in an inclined state. SOLUTION: In the case of acquiring an image while successively scanning paper moneys carried, a minor length corresponding to the arrangement of non-transmissible pixel values is obtained in each scanning line together with its distribution (S1) and the maximum frequency value of the minor lengths is obtained from the above distribution (S2). After checking where an inclination angle can be correctly detected or not (S3), the inclination angle is detected from the minor length start coordinates of scanning lines on upper and lower ends having the maximum frequency value (S5). Then, a paper money area is calculated (S6), an excess inclination angle is checked (S7), and after checking the dispersions of inclination angles (S8), an inlination is corrected based on the inclination angle thus obtained (S9).  Since the most frequent minor length is acquired by the search of minor lengths and an inclination angle is detected by coordinates having the most frequency length, the processing of an image can be executed simultaneously with its image pickup and a high speed processing can be attained.
