Title: Speed controller for motor
Inventor: FUTAGAWA YOSHIKIYO
IPC: H02P29/00
Filed: 1985-11-28
Abstract: PURPOSE:To control the speed of a motor in a wide range by providing a counter for detecting the length of a desired period of an encoder period. CONSTITUTION:Second and third counters 20, 21 are alternately reset to an initial value whenever an encoder signal is input. The counters 20, 21 outputs carriers when arriving at counted values corresponding to a desired rotating period of a motor to be stored in memory circuits 22, 23 erased by the encoder signal. The circuits 22, 23 detect longer and shorter signals than the desired period of an input period of the encoder signal. When the longer signal is generated, the input clock of a first counter 5 is switched to the clock of higher frequency than a reference clock to accelerate a carrier discharge phase of the counter 5 to increase a phase difference from the encoder signal, thereby increasing the energizing power of a motor. When the shorter signal is generated, the phase difference is reduced with the clock of lower frequency to properly set the motor energizing power.

Title: Display
Inventor: TODA TOSHITAKA
IPC: G02F1/1335
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To prevent the light transmitted through an aperture from being accompanied with a noise component at a periphery part, to avoide a crosstalk between picture elements and to make a display stoyby visible by making the display have a distribution of transmissivity or reflectance which is made lower as going to the periphery part from the center part of a cell. SOLUTION: By setting the transmissivity distribution or the reflectance distribution in the cell (aperture) being the picture element so that the transmissivity or the reflectance may be reduced from the center part to the periphery part at least in one direction, the intensity of emitted light in a main lobe is made uniform. The intensity distribution of the emitted light from the aperture is related to amplitude distribution being a square root. In the case of making the transmissivity distribution at the center part of the aperture definite and reducing the transmissivity from the position as being away from the center part toward the periphery part (waveform is made trapezoidal), the intensity distribution becomes a trapezoidal function.  When the amplitude transmissivity of the aperture is the trapezoidal function, the utilization efficiency of incident light is enhanced because the intensity of the emitted light is made high at the center part while keeping the reduction of the intensity at the periphery part in the intensity distribution of the emitted light.
