Title: Pll synthesizer receiver
Inventor: OOTANI KOUICHI
IPC: H03J5/02
Filed: 1983-06-14
Abstract: PURPOSE:To simplify a circuit constitution and to attain state and sure operation of a receiver by extracting a local oscillator signal component with high level from an output side of a mixer and using it as a comparison signal of a PLL. CONSTITUTION:A high frequency signal RF of a high frequency amplifier 3 and ab output LO of a local oscillator 5 are applied directly to the input side of the mixer 4, causing the level of the local oscillating signal component at the output side of the mixer 4 to be increased. Thus, the local oscillating signal component is supplied to a frequency divider 8 of the prestage via a high pass filter 15 from the output side of the mixer 4, thereby eliminating the need for a preamplifier, and it is not necessary to supply the local oscillating signal to the pre-amplifier separately from the local oscillator 5 to the output of the mixer 4. As a result, the possibility of generation of parasitic oscillation and discontinuous oscillation or the like is precluded, the adverse effect to be exerted on the variable oscillator of a phase locked loop PLL is prevented and the operation of the receiver is made stable and sure.

Title: Active matrix type liquid crystal display element
Inventor: KEYAKIDA MASAYA
IPC: G02F1/1368
Filed: 1990-04-24
Abstract: PURPOSE:To substantially completely eliminate defective modes by connecting TFTs of an n channel and TFTs of a p channel to the same and applying the voltages of gate electrodes respectively independently thereto. CONSTITUTION:If a gate pulse is impressed to the scanning electrode of a TFT element, the potential of the counter electrode is like 10, the voltage to be impressed to the gate electrode of the n channel TFT 6 through the 1st scanning electrode 1 is like 11 and the voltage to be impressed to the gate electrode of the p channel TFT 7 through the 2nd scanning electrode 2 is like 12. A charge is written to the liquid crystal of the same picture element through the p channel TFT 7 in the next field if this charge is assumed to be written in the liquid crystal of one picture element by using the n channel TFT 6. The gate potential shifts to a negative direction after the charge is written by using the n channel TFT 6 and, therefore, the picture element electrode potential is shifted to the negative direction as well by the influence of a parasitic capacity. The gate potential is shifted to a positive direction after the writing of the charge by using the p channel TFT 7 in the next frame. The asymmetry of the impressed voltage is, therefore, always negated regardless of the state of the liquid crystal.

Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To enhance adhesion strength between a spherical substance and an adhesive material by uniformly forming a plurality of fine recesses and projections on the surface of the spherical substance which is to be used as the core of an adhesive spacer. SOLUTION: A rugged pattern is formed by pixel electrodes or the like on one of substrates 2, 3 facing each other, especially on the lower substrate 2. An adhesive 6 is deposited around spherical substances 5, which are to be the cores of the adhesive spacers 4 sprayed between the substrates 2, 3 so as to form a gap between the substrates 2, 3. Then the gap is filled with a liquid crystal 8. In this method, a plurality of recesses 7 are formed on the surfaces of the spherical substances 5 as the cores. The adhesive 6 adheres tightly to and infiltrates into the recesses of the spherical substances 5, and further tightly adheres to the substrate 2 beneath. With such a constitution, since the contact area between the spherical substances 5 having recesses 7 and the adhesive 6 increases, the adhesion strength between both increases and the adhesive spacers 4 become harder to move.  Therefore, an irregular display of the liquid crystal display caused by the movement of the adhesive spacers 4 can be decreased, and a high-quality liquid crystal display device 1 can be obtd.
