| <P>PROBLEM TO BE SOLVED: To provide a temperature control change gear circuit that can prevent switching noise caused by controlling a rotational speed in a fan motor and has a wider range, in which the rotational speed in the fan motor can be controlled, as compared with conventional control methods by pulse-width modulation. <P>SOLUTION: The temperature control change gear circuit 31 is connected to a drive circuit 32. The drive circuit 32 drives a fan motor 13 by a drive voltage, outputted by the temperature control change gear circuit and controls the rotational speed. The temperature control change gear circuit 31 includes a reference voltage output circuit 311 and a drive voltage control circuit 312. The reference voltage output circuit 311 outputs a corresponding reference voltage signal Vref, based on the change in the environmental temperature. The output end of the reference voltage signal Vref is connected to a first resistor R1 in series and is simultaneously connected to the second resistor R2 in parallel. The drive voltage control circuit 312 outputs a corresponding drive voltage VD, based on the reference voltage signal Vref. <P>COPYRIGHT: (C)2005,JPO&NCIPI | ||||||

| PROBLEM TO BE SOLVED: To provide a damping operation method which never changes the cut-off angle frequency of a control system that is obtained as a damping operation result in comparison with the anglar frequency that was obtained before connection of a damping transfer function. SOLUTION: The cut-off anglar frequency ωc are inputted together with the variation angle frequency Δωc , an anglar frequency step Δω and an allowable response error ε. The equidistant inverse functions T1 and T2 are calculated based on the frequency ωc and Δωc . Then an indicial response C is calculated based on both functions T1 and T2 , and it is judged whether the response C is equal to a prescribed response. When a prescribed response C is judged, the functions T1 and T2 are set at damping constants TD1 and TD2 respectively. | ||||||

| PURPOSE:To detect an oscillation angle by operation by calculating the travel distance of a rope laid across first and second guide pulleys, the horizontal distance between a third guide pulley and a set of the first and second guide pulleys, and the vertical distance between the third guide pulley and the rope laid across the first and second pulleys when a hoisting tool is oscillated. CONSTITUTION:When the horizontal travel distance of a hoisting tool 2 is set to S, an oscillation angle is theta, the horizontal distance between a third guide pulley 13 and a set of first and second guide pulleys 11, 12 prior to oscillation is set to (a), the length of each rope 17 is set to L, the lengths of the respective ropes 17 after contact are set to L1, L2, the change of length is set to (x), and the vertical length is set to (h), x=(L1-L2)/2=(L1<2>-L2<2>)/[2(L1+L2)]=4aS /[2(L2-L1)]=4aS/(2X2L)=aS/L..., and theta S/h concerning an oscillation angle thetaare established. Accordingly, theta Lx/(ha). h and L are values easily obtained from the deliver amount of a suspending wire. | ||||||

| PURPOSE: To secure high tracking accuracy without decreasing the zooming speed is obtained corresponding to a zoom position, and controlling the rotating speed of a zoom motor. CONSTITUTION: A 2nd group lens 22 is driven by a zoom motor 28to shift in position momentarily and when a zoom position detection part 30 judges that the 2nd group lens 22 reaches a point A where the inclination of a tracking curve increases abruptly from the information of a zoom encoder 27, a zoom speed determination part 34 determines a driving condition for decreasing the zoom speed; and the rotating speed of the zoom motor 28 is decreased to decrease the inclination of the tracking curve, i.e. ▵f/▵v. Further, the zooming speed is decreased stepwise toward the telephoto end to perform the zooming operation up to the telephoto end point E without increasing the inclination value of the tracking curve.
