Title: Suntracking mechanism for solar energy-powered device
Inventor: MOTODA KENROU
IPC: F24S50/20
Filed: 1980-05-19
Abstract: PURPOSE: To perform the suntracking operation of a solar energy-powered device at lower cost without the needs for a separate energy by providing a heat sensor filled with a fluid which expands or evaporates by the irradiation of solar radiation beam and turning a heat collector by the expanding or vapor pressure of the fluid.  
     CONSTITUTION: When setting up a heat collector 5 by turning it toward the sun, the sunlight is reflected and focused by a reflection plate 6 and the focused solar radiation beam is irradiated on a collector 7, thereby heating a heat medium inside the collector 7. At this time, no solar radiation beam is irradiated on a heat sensor 10, so that the expansion of the fluid 11 inside the sensor 10 is slight. Then, when the solar radiation beam is gradually displaced out of the collector 7 as the sun moves and then irradiates on the heat sensor 10, the fluid 11 present in the sensor 10 is expanded to extend a pressure conversion means 12, whereupon oppositely directed turning torque acts on the heat collector 5 and the heat sensor 10 but the heat sensor 10 alone is turned and its attitude is controlled because the reverse turning of the heat sensor 10 is hindered by the reverse-turning preventing mechanism 18b of a supporter 15b for the heat sensor 10.

Filed: 1988-03-18
Abstract: PURPOSE: To draw a completely closed quadratic curve with a continuous shifting single cursor by plotting a circle by a mode advancing continuously from an octant to a next octant and returning to the original place again. CONSTITUTION: The arc of a curve is drawn by repeating point-to-point correspondence plotting in a first octant by using the reference of a relative coordinate. Further, as the origin of the curve drawn in a second octant, the last point drawn in the first octant is adopted. The new U and V references of relative coordinate of the second octant as the function of the tangent drawn on the curve at this new origin and the direction of the displacement on the curve. By including the value of the last point drawn in the first octant in a register, the initial value related to this new U and Y reference for the picture in this second octant is calculated. The arc of the curve in the second octant is drawn by repeating point-to-point correspondence plotting by using the new reference of the relative coordinate.  The work determining the reference of the relative coordinate and drawing in all the octants covered by the arc of the curve is restarted.

Title: Method for measuring electric angle offset of motor
Inventor: URANO HIROAKI
IPC: H02P21/06
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To accurately measure an offset of an AC motor by measuring an electric angle deviation based on behavior of the motor. SOLUTION: A torque detector 14 detects a torque of an output shaft 12, and an offset deciding unit 20 judges whether a set value of present offset value is suitable or not based on the torque detected value. If the set offset value is suitable, torque expected from a control command is output. If it is not suitable, the torque expected is not output. When the unit 20 decides suitable present offset value, this set value is output as offset value of the motor 10 under test. When the unit 20 decides not suitable value, a change command of the set value of the offset is output to a testing motor command unit 18. The unit 18 changes the set value based on the change command, and again controls the motor 10 according to the change value. And, the change of the set value is repeated until the set value of the offset is judged suitable.

Title: Installation method of outlet works buried inside dam bank and device thereof
Inventor: MIYAKE TAKANORI
IPC: E02B7/00
Filed: 1994-03-08
Abstract: PURPOSE:To rationalize the installation work of outlet works to be buried in a bank of a dam. CONSTITUTION:A working rack 1 is temporarily constructed in an adjacent vacant lot outside a bank in an elevation substantially equivalent to the position of outlet works 3. The outlet works 3 are assembled on the rack by way of a movable device 2. Concrete is placed on the bank at the same time. When the concrete placement reaches an installation surface P, the assembled outlet works 3 are arranged to slide transversely so that they may move on the concrete placement surface, thereby burying the outlet works 3 by the resumed concrete placement. Then, the working rack 1 is removed. When the bank is constructed based on a whole surface layer placement method or especially an RCD method, the outlet works 3 are installed on the way, which makes it possible to limit dramatically an obstruction period which interrupts the concrete placement work and hence reduce the whole construction period. This construction makes it possible to contribute to on-site work safety.
