Title: Detecting method of abnormal fusion
Inventor: MIZUKAWA KENJI
IPC: G01N27/04
Filed: 1991-05-10
Abstract: PURPOSE:To make it possible to detect abnormal fusion due to output undervoltage and overvoltage by a method wherein the minimum output current value is not memorized over the predetermined period of time before and after the deviation of output voltage from the predetermined range in comparison with reference voltage. CONSTITUTION:A microcomputer 13 memorizes the minimum output current value at fusion operation and judges as abnormal fusion when the output current value becomes larger than the minimum output current value by the predetermined percent over the predetermined period of time. Further, when the output voltage deviates from the predetermined range in comparison with reference voltage, the microcomputer does not memorize the minimum output current value over the predetermined period of time before and after the deviation and does not compare the output current value with the minimum current value for the predetermined period of time since the deviation.

Title: Measuring device of image by pattern matching
Inventor: NOGAMI MASARU
IPC: G01B11/00
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent detection errors even when the contrast of the reference image used in the pattern matching and that of a pattern to be actually measured do not agree with each other by registering and using a plurality of reference images for pattern matching in the automatic positioning. SOLUTION: An image (a) of an object is picked up by a camera, a reference image 3 is registered, then an image (b) is picked up by the camera, and a reference image 6 is registered. The part same as the reference image is detected from the camera image by the pattern matching on the basis of the reference image 3. On this occasion, when the camera image is a photographed image 4, it does not have the part same as the reference image 3. When the detection error is generated on the image of the reference image 3, the pattern matching is continuously performed by using an image of the reference image 6 to detect a part of the registration position. The set number of the reference images is, for example, four in maximum. The order of the reference images to be used is determined by an operator, or can be automatically changed.

Title: Chinese character input device
Inventor: AIKAWA TAKESHI
IPC: G06F17/22
Filed: 1979-08-24
Abstract: PURPOSE: To decrease the number of candidates to be selected, by allotting the specific reading to the Chinese character in the form of the key and then supplying the reading along with other readings simultaneously in the form of the key when the Chinese character is suppied again.  
     CONSTITUTION: The reading corresponding the "Japanese language" is supplied through the kana (Japanese syllabary) keyboard 7 and then stored in the memory device 10. The reading is then cut out with every reading corresponding to one Chinese character by the reading cut-out device 4 after being sent to the floppy disk control device 2. Device 2 gives an access to the floppy disk device 1 with the reading used as the key and then reads out the Chinese character condidate corresponding to the reading to then store it in the buffer memory 3. The local memory 11 stores the Chinese characrers which were used in the past. And the device 2 reads out the Chinese character candidate out of the memory 11 in case the specific reading is designated. Then the candidate selector 5 reads out the candidate from the memory 3 and then displays it on the display 6. As the two readings are supplied to one Chinese character, the selector 5 secures the AND of the candidate group. As a result, the number of candidates can be decreased.

IPC: B66B1/30
Filed: 1995-05-01
Abstract: PURPOSE: To provide an elevator control device and a control method suppressing the vertical vibration of a car to improve a speed follow-up characteristic so as to shorten landing time, to heighten landing accuracy and to ensure a riding comfort. CONSTITUTION: A grade of disturbance acting upon an elevator is estimated by a disturbance estimator 8 from the target speed of a car and the actual speed of the car. An arithmetic element 15 subtracts driving force, detected by a driving force detecting device, from the output of a converter 7 for converting the output of a target car speed generator 5 into target driving force, so as to compute the fluctuating component of driving force. The arithmetic element 15 further subtracts the estimated disturbance from the fluctuating component of driving force, and the output is returned to the command of a controller 13 for a motor 3 through a gain device 12. Disturbance and vibration of the car in a high frequency area is thereby compensated by the return of the fluctuating component of driving force, and disturbance and the vibration of the car in a low frequency area is compensated by disturbance compensation by the disturbance estimator 8 so as to suppress the vertical vibration of the elevator.
