Title: Image reader
Inventor: USAMI AKIHIRO
IPC: H04N1/028
Filed: 1984-03-23
Abstract: PURPOSE:To prevent moire interference by providing a birefringent material which separates a linear polarized component, a rotary polarizing material which rotates a plane of polarization by 45 deg., and a birefringent material which separates a polarized component at right angles to the direction of said separation in the optical path of an optical system. CONSTITUTION:An original image is formed on a photoelectric element array 2 through the optical system and read. A filter 25 is provided in the optical path of said optical system and is formed by laminating a birefringent plate 26, rotary polarizing plate 27, and birefringent plate 28 in order. The optical axis 29a of the birefringent plate 26 slants at 45 deg. to the main scanning direction X of the array 2. The rotary polarizing plate 2 is thick enough to rotate a plane of polarization by 45 deg. and the optical axis 28a of the birefringent plate 28 slants at 45 deg. to the subscanning direction Y. Consequently, image light is separated into four points and spread through the filter 25. The separation width is 1/4-1/2 as large as the picture element combination unit of photodetecting elements. Consequently, moire interference is prevented and interference fringes of the image are eliminated.

Title: Controlling method for inverter
Inventor: HAYASHI HIDEKI
IPC: H02P27/06
Filed: 1980-04-30
Abstract: PURPOSE:To prevent the decrease in the current of an inverter by raising a voltage command input signal when the frequency command input signal of an inverter controlling circuit is raised. CONSTITUTION:When the signal of a frequency setting unit 5 is increased and the primary frequency of a motor is temporarily raised, its primary current tends to decrease, but a differentiator 15 detects the rise of the frequency command input signal and raises the voltage command input signal through an adder 16, thereby preventing the decrease of the primary current. The primary current will not almost vary by selecting suitably the gain of the differentiator 15. When the signal of a slip frequency setting unit 5 is decreased, the rise of the primary current can be prevented by the similar operation.
