Title: Liquid crystal projector
Inventor: OTA MASA
IPC: G02B5/30
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain high-quality color images which are not unsightly and are smooth by selectively separating the extraordinary rays of incident light by as much as the pitch-components of the pixels of a liquid crystal display element from the ordinary rays by double refraction and emitting these rays. SOLUTION: The luminous fluxes emitted from a light source 1 are separated through a green transmission dichroic filter 2 to the transmitted green luminous fluxes and the reflected magenta luminous fluxes. The reflected magenta luminous fluxes are made incident on optical systems 4 to 8 through a total reflection mirror 3. The emitted linearly polarized light is converted by a quarter- wave plate 7 to elliptically polarized light which is made incident on a double refractive element 8. The double refractive element 8 is so adjusted in its optical axis that the ordinary rays advance rectilinearly and that the extraordinary rays are emitted to the adjacent pixels. R, B longitudinal stripe filters are arranged on the surfaces of the liquid crystals 5 and, therefore, the components of R+B are added in correspondence to the respective pixels and are outputted.  On the other hand, the transmitted green luminous fluxes are added with the magenta luminous fluxes by a green reflection dichroic mirror 13, by which the color images are projected.

Title: Boosting circuit
Inventor: INOUE YOSHINAGA
IPC: H03K5/02
Filed: 1988-12-28
Abstract: PURPOSE:To eliminate the need for a circuit generating a timing signal and to reduce the chip area by using a charge means so as to always charge a prescribed node, preventing the decrease in the level, retarding an output signal with a delay means and using the resulting signal as a signal for boosting the prescribed node. CONSTITUTION:Suppose that an input signal phiX' is at an H level in the initial state and an output signal phiX is at an L level, then with the input signal phiX' reaching the L level, a P-channel MOSFET 3 is turned on and an N-channel MOSFET 4 is turned off. As a result, a wire capacitance 8 of an output signal 6 is charged and the level of a node A is recovered to a level of (Vcc-Vth). Then a delay signal resulting from the output signal phiX is supplied to a boost capacitor 10 by a delay circuit 90 comprising an even number of inverters 9a-9d. It results in raising the level of the node A to (Vcc-Vth+alpha) through the capacitive coupling by a boosting capacitor 10. Thus, the level of the output signal phiX reaches the level of (Vcc-vth+alpha).

Abstract: PURPOSE:To prevent the effect to be given on the characteristic of normal operation and to constitute a flip-flop circuit as a shift register by providing a terminal provided with a delay circuit and a terminal not provided to a shift-in input or an output of the flip-flop circuit possible for scan path constitution.

Title: Distance measuring method using optical wave distance meter
Inventor: ICHIKAWA YUKIHISA
IPC: G01S17/36
Filed: 1991-12-17
Abstract: PURPOSE:To eliminate time delay wasteful and shorten the measuring time by starting counting of wave number immediately when changing-over takes place between a distance measuring signal and reference signal at the time of changing over the modulation signal, and repeating the counting. CONSTITUTION:A frequency f1 select signal input 1 is selected 21 on the basis of a shutter changeover signal of a CPU 4, and the distance measuring light amplitude modulated with the frequency f1 is fed to a light receiving element by selecting 22 of an input 4. The CPU 4 changes over a shutter so that the input 5 is selected 22 and the reference light enters the light receiving element. This changing-over is equipped with a delay of approx. 10msec, and a count start signal is sent to a counter 3, and the reference signal pulses corresponding to the phase difference between the distance measuring signal and reference signal are counted to obtain the count value. When this counting is repeated three times, judgement takes place whether each count value lies within the specified error scope, and if within it, the count value is taken in a necessary times to calculate the distance from a reflex mirror. Adding the judging time for three times to 10msec results in approx. 100msec, as a shortening of the delay time to half the conventional which has been 200msec.
