Title: Controlling commutation lead angle of commutatorless motor
Inventor: SUZUKI SEIJI
IPC: H02P6/08
Filed: 1978-03-02
Abstract: PURPOSE: To minimize the necessary commutation lead angle of a motor depending of its speed, by making driving signals for a power inverter from sine wave signals which are produced by the transformation of phase voltage signals so that the amplitude of the driving signals is small when the speed of the motor is low.  
     CONSTITUTION: The phase voltage signals of Vu∼Vw of the motor 14 are removed of sharp- pointed pulses by a filter 5 so that basic phase voltage wave signals Eu∼Ew are generated. These basic phase voltage wave signals are multiplied by the output voltage Vf of a tachometer generator 15 through a multiplier of a position detection signal compensation circuit 9, thereby producing the driving signals Ex∼Ez, whose amplitude is small when the speed of the motor is low (Vf1) but large when the speed is high (Vf2). These driving signals are applied to a logical signal conversion circuit 6 so that they are added at the inverse polarity to the basic phase voltage wave signals Eu∼Ew. Polarity-detected position signals PS1∼PS3 are supplied from the conversion circuit 6 to drive the power inverter 3 through a logical gate circuit 7 and a gate pulse generation circuit 8. As a result, the necessary commutation lead angle β of the motor is minimized depending on its speed, the power-factor and efficiency of the motor in its slow run are inproved and the torque ripple is decreased reduced.

Filed: 1988-02-03
Abstract: PURPOSE:To inexpensively suppress an increase in panel thickness by providing an org. film for optical compensation between the outside surface of the panel on a light exist side or light incident side and a polarizing plate. CONSTITUTION:The cholesteric liquid crystal polymer film for optical compensation which is a solid consisting of a liquid crystal polymer having a cholesteric liquid crystal structure is installed to the light exit side of the TN (twisted nematic) or STN (super twisted nematic) liquid crystal panel.

Title: Binary transversal filter
Inventor: OGAWA KAZUO
IPC: H03H15/02
Filed: 1979-03-02
Abstract: PURPOSE: To reduce the clock component by supplying the input NRZ signal to the shift register with no conversion into the RZ signal and then driving the shift register by the clock of several times as much as the NRZ signal.  
     CONSTITUTION: Input NRZ signal (in) is applied directly to shift register SHR of n-step, and register SHR is driven by the timing signal obtained by giving M-multiplication to clock clk through multiplying circuit MLT. At the same time, the output of each step is applied to weighting resistances R -n ∼R n , and the output of R -n ∼R n  are applied to operational amplifier OPA. And the composite output obtained through amplifier OPA is delivered to output signal (out) via low band pass filter LPF which eliminates the frequency component of over 2/T (T: repetitive cycle of input NRZ signal). Then the transmission characteristics is turned into zero via the clock frequency of 1/T when multiplication number M is doubled. Thus the clock component can be reduced.

Title: Fine pattern inspection device
Inventor: IWATA SATOSHI
IPC: G01B11/24
Filed: 1988-02-05
Abstract: PURPOSE:To inspect a three-dimensional shape by guiding out and detecting the reflected linear beam light of slit passing light from a projection side and its opposite side through the same objective. CONSTITUTION:Incident light is passes through the slit part (a) of a liquid- crystal device LCD 32 to become (x)-directional thin linear illumination light, which has its polarization direction in a (y)-direction and passes through a polarizing plate 33. The light passes through the other part is cut off by the plate 33. A 1/4-wavelength plate 35 converts the output light of the LCD 34 into circular polarized light, which is converged by the objective 26 to form a linear beam 37 on an object. The reflected light of the beam 37 is polarized circularly through a lens 36 and converted by the plate 35 into linear polarized light; and parts 1 and 2 pass through an LCD 34 as they are and the remainder is polarized in the (y)-direction. The (y)-directional output light of the LCD 34 passes through the part other than the slit part (a) of the LCD 32 as it is to generate output light. A polarizing prism 31 is deflected at right angles to the light in the (y) direction to generate detection light 38. Consequently, the three-dimensional shape can be detected and the detection accuracy of the fine pattern is improved.
