IPC: G01B11/26
Filed: 1995-05-31
Abstract: PURPOSE: To provide a calibration method when a two-dimensional coordinate is measured in a noncontact dimension-measuring apparatus whereby a coordinate of an object to be measured is calibrated by measuring center coordinates and deviation angle of a lens of a CCD camera. CONSTITUTION: A calibration reference test piece 21 having two projections at one corner is arranged as an object to be measured. Sight angles of these two projections 22 are detected by a camera 3 (3A, 3B). Center coordinates and deviation angle of a lens of the camera 3 (3A, 3B) are obtained by operations using the angles of line of sight of the projections 22 and a coordinate of a known projections 22. A coordinate of the object to be measured is calibrated. Since the center coordinate and deviation angle of the lens 11 of the camera 3 (3A, 3B) can be detected correctly, a correct reference position and a correct posture of the camera 3 (3A, 3B) can be obtained. Accordingly, the coordinate of the object can be calibrated and a size of the object can be obtained correctly.

Filed: 1992-05-26
Abstract: PURPOSE:To prevent the clouding of a lens surface by forming a base from a heat conductive material, charging heat-conductive liquid, metal powder, and metal particle between the lens surface and the lens reverse surface. CONSTITUTION:A base 1B is formed of a plastic containing carbon or metal fiber, heat-conductive liquid silicon, metal powder, and metal particle 8 are charged in the space 1C between a lens 1A and the base 1B to adhere the lens 1A to the base 1B.

Title: Trouble detector for elevator
Inventor: INABA HIROMI
IPC: B66B5/00
Filed: 1977-11-09
Abstract: PURPOSE: To always make the detecting sensitivity sufficient and minimize the shut-up trouble due to the emergency stop, by adjusting the gain of a comparator through a sensitivity adjusting relay and automatically varying the detecting sensitivity depending on the operating condition.  
     CONSTITUTION: When a contact 60 of a deceleration preparing relay for producing a decelerating instruction signal is closed, the sensitivity adjusting relay 50 is turned on and a gain adjusting resistor 194 is partially short-circuited and the gain of the comparator 193 is reduced. As a result, the non-detection range of the trouble detector is widened. When one notch is not turned off during the deceleration or when a  slow-down unit operates, the trouble detector operates to turn on relay 20 to emergency-stop the elevator. Thereby, the passenger is prevented from being shut up in  the gondola.

Title: Motor controller
Inventor: YAMAUCHI AKIRA
IPC: H02H7/085
Filed: 1990-05-23
Abstract: PURPOSE:To find erroneous setting of a reference value for judging fault or erroneous application of motor easily and to prevent operation under erroneously set state by setting a rated current and a starting time in a memory circuit and automatically notifying a fact that the starting current does not match with a set value at the time of test operation. CONSTITUTION:A current detecting circuit 12 detects starting current of a motor 2 flowing into a main circuit 1 and a detection signal is fed to a comparing circuit 18. Since the starting current is approximately constant depending on the rated current of the motor 2, no signal is outputted from the comparing circuit 18 if the rated current and starting time set in a memory circuit 17 correspond to the rated values of the motor 2. When a fault judging reference value, a rated current and a starting time are set for a motor having higher rated values than an actual machine, the comparing circuit 18 provides an unmatching signal to a logic operation circuit 14 which then outputs a sound or an alarm to the outside through an outside output circuit 15 while furthermore provides a display on a display circuit 15.
