Title: Liquid crystal display element and its manufacture
Inventor: MOCHIZUKI HIDEAKI
IPC: G02F1/13
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display element where a defect on a display part due to foreign matter is inconspicuous by forming a barrier rib at the periphery of a pixel electrode. SOLUTION: A barrier rib 20 is provided at the periphery of each pixel electrode of a liquid crystal display element 1. The height of the harrier rib is set to >=1/2 of the thickness of a liquid crystal layer or the material of the barrier rib is so selected that the alignment of liquid crystal molecules at the barrier rib is vertical. Consequently, even if there is foreign matter present in the liquid crystal 10 of each pixel, an abnormally aligned area at the periphery of the foreign matter can be confined to the pixel. Eventually, the ratio of visible pixel defects can be reduced even in the presence of the foreign matter.

Filed: 1993-03-10
Abstract: PURPOSE:To develop high filtering capacity in a filter medium for an air cleaner containing a nonwoven fabric formed by partially fixing fibers based on long thermoplastic synthetic resin fibers by heat treatment by reducing the increase in the air passing resistance of the nonwoven fabric by heat treatment. CONSTITUTION:A filter medium 10 is constituted of a laminate wherein an inlet side layer 12 composed of a nonwoven fabric formed from a long polyester fiber, an intermediate layer 14 being a mixed fiber layer consisting a of short polyester fiber and a short rayon fiber and an outlet side layer 16 are bonded by needle punching.

Abstract: PURPOSE:To obtain a flip-flop circuit operated at a low power consumption and suitable for circuit integration by providing a transistor (TR), a resistor and a current supply circuit to an output of cross coupling of two TRs. CONSTITUTION:When a switch S2 is turned off and a voltage of a battery 17 is applied to a power supply line 16, a charging current flows to a capacitor C2, a current flows to each base of TRs Q6, Q7 so as to drive TRs Q10, Q11 via a TRQ9. Further, the TRQ6 is turned on and the TRQ5 is turned off. Since the TRQ6 is saturated, a base potential of the TRQ7 is higher by e.g. 20mV at the unsaturating state and a collector current of 20(mV)/R2+R3) flows. In taking the R2+R3 as 40kOMEGA, the current of 0.5muA flows to the TRs Q9-Q11, then a current consumption of 1.5mum is formed as a whole, thereby allowing a low power consumption. When the switch S2 is turned on, the polarity is inverted, a current is applied from the TRs Q10, Q11 and a sufficient current flows to a load circuit 18.

Abstract: PURPOSE:To enable to obtain good light emitting characteristics and electrical characteristics by a method wherein P type Cu(AxGa1-x)(SySe1-y)2 and N type Zn (SxSe1-x) are successively epitaxially grown on a P type GaP single crystal substrate. CONSTITUTION:The P type Cu(AxGa1-xSySe1-y)2 12 is grown on said substrate 11; (0<=x<=1, 0<=y<=1), by vapor phase growing method. Next, the N type Zn(Sx Se1-x) epitaxial layer 13 is formed thereon; (0<=z<=1). Further, the epitaxial growth of N type GaP 14 thereon is also available. Ohmic electrodes 15 and 16 are formed on the layers 11 and 13 or 14 or an epitaxial wafer manufactured in such a manner, respectively. By this construction, light emission is caused by the recombination of carriers injected from the layer 13 to a layer 12, however, the emitted light can be well led out of the surface of the layer 13, since the layer 13 has a forbidden band width larger than that of the energy of said light. Besides, the formation of the layer 14 on the layer 13 leads to easy production of an ohmic contact.
