Title: Plane confronting brushless motor
Inventor: NAKAJIMA TOSHIHIKO
IPC: H02K29/00
Filed: 1981-12-21
Abstract: PURPOSE:To reduce variation of torque of the plane confronting brushless motor by a method wherein distribution of magnetic flux density to be inputted to a Hall element and distribution of magnetic flux density for generation of torque are made as to differ. CONSTITUTION:No non-magnetized part exists in the neighborhood of the outside circumference to generate magnetic flux to be inputted to the Hall element, and two poles of S, N are magnetized respectively at pi radian by pi radian between the interval of phase angle 2pi radian. Moreover, in the neighborhood of the circumference of the radius r3 constituting the boundary of magnetization between the inside circumferential part and the outside circumferential part, distribution of magnetic flux density varies continuously toward the outside circumference from the inside circumference. When magnetization as mentioned above is performed, the variation ratio of output in the neighborhood of the place at where the sign of output of the Hall element reverses is enlarged rapidly, the influence of an unbalanced voltage between output of the Hall element and input of an amplifier is reduced, and variation of torque can be also reduced.

Filed: 1986-09-03
Abstract: PURPOSE:To maintain parallelism strictly between a plate and a surface plate, by positioning the center of operation of the plate onto a polishing face through a parallelism maintaining mechanism comprising a spherical bearing between the plate and a shaft or supporting said plate. CONSTITUTION:A wafer W sucked to the underface of a plate 4 is pressed with a predetermined pressure P against a polishing cloth 2 sticked onto a surface plate 1 rotatable horizontally with a constant speed.

Abstract: PURPOSE:To keep a filter capacitor voltage in constant and to shorten a dead time by connecting an overvoltage protective circuit composed of a series circuit of a resistance and a thyristor having a power of self-extinction of arc in parallel with the filter capacitor. CONSTITUTION:If an electrically incomplete contact on a sliding face occurs at an S point of time, a voltage of filter capacitor FC abruptly decreases and a converter CONV stops at an A point of time.

At a C-point of time, an overvoltage detector VD is operated, a thyristor Th1 having a power of self-extinction of arc is ignited and a voltage of the filter capacitor FC is suppressed. Then, the thyristor Th1 is controlled by chopping to keep a voltage of the filter capacitor in constant. Then, the converter CONV returns to operation from a D-point of time.

Abstract: PURPOSE:To accurately measure the curve of a tubular rod type body without being affected by vibrations of a body to be measured by providing a supporting device which supports the body to be measured in a two-point supporting beam shape and is equipped with a rotary mechanism. CONSTITUTION:The supporting device is provided which supports the body to be measured in the two-point supporting beam state and is equipped with the rotary mechanism, and a distance detector is also provided which detects the separation distance between the outer peripheral surface of the body to be measured at plural lengthwise points of a beam part and a reference position. Then while the body to be measured is rotated, the separation distance is detected and the curve of the body to be measured is calculated from the difference between the maximum and minimum values of the separation distance within one turn at plural points of the body to be measured. In this case, points where bodies of various size to be measured are changed to adjust the current natural vibration frequency. Further, the rotating speed is varied properly to the external diameter of the body to be measured to adjust its frequency. Thus, a low-pass filter is used to remove natural frequency components which cause errors.

Title: Zoom lens with flare stop
Inventor: OIZUMI KOJI
IPC: G02B13/18
Filed: 1990-08-03
Abstract: PURPOSE:To effectively remove a flare and to easily obtain high optical performance over the entire power variation range by arranging the flare stop at a proper position for two lens groups which move according to power variation and have refracting power of focus, and moving them on the optical axis under specific condition. CONSTITUTION:When the power is varied from the wide angle end to the telephoto end, an aperture stop 3 and a 1st group 1 are moved in one body and the flare stop 4 and a 2nd group 2 are moved integrally toward the object side. At this time, the interval between the flare stop 4 and 1st group 1 is increased gradually as the power is varied from the wide-angle end to the telephoto end and made longest at the telephoto end. The flare stop 4 shuts off off-axis luminous flux 7 of off-axis luminous flux 6 on the telephoto side which becomes a lower flare, so aberrations need not be compensated as to the off-axis luminous flux 7 which does not reach an image plane. Consequently, the off-axis luminous flux 7 of the off-axis luminous flux 6 which becomes the flare can effectively be shut off and even when the number of lenses is decreased, the high optical performance is obtained over the entire power variation range.
