摘要:
An optical receiving circuit comprises a photodetector, a differential transimpedance amplifier, a peak detector, a resistor network circuit and a discriminator. The transimpedance amplifier receives a current pulse converted by the photo-detector and outputs a non-inverting voltage signal and an inverting voltage signal of the same level. A peak detector for detecting a peak value of the non-inverting voltage signal. A resistor network circuit make an additional operations between an output signal from the peak detector and the inverted voltage signal, and between the non-inverting voltage signal and the non-inverting voltage signal, thereby generating two complemental voltage signals, which have the same amplitude and cross each other at a middle point of the amplitude. The discriminator discriminates a crossing potential at which the two complemental voltage signals generated by the resistor network circuit and generates a pulse-shaped signal with a logical level whose state is changed to another logical state at the crossing potential.

摘要:
For a liquid crystal display apparatus, an orientating film of an electrode substrate including more signal electrodes than scanning electrodes in a predetermined range receives a uniaxial orientation treatment parallelly or almost parallelly to a lengthwise direction of the signal electrodes. Besides, an orientating film of an electrode substrate including the scanning electrodes receives a uniaxial orientation treatment perpendicularly or almost perpendicularly to a lengthwise direction of the scanning electrodes. The electrode substrates are combined so that the directions of the uniaxial orientation treatment of the orientation films become parallel to each other. This enables growth of a smectic layer to be less frequently hindered by differences in level caused by the electrodes. Thus a uniform C2U orientation can be obtained easily. Consequently, the liquid crystal display apparatus realizes a uniform orientational state with no defects and uniform and high-contrast display properties.

A semiconductor package is described which is constructed from a rectangular tape film, a wiring pattern formed on the tape film constituted by wiring composed of a conductive material, a semiconductor chip electrically connected to one end of the wiring pattern, and holes formed on the other end of the wiring pattern for connection by insertion of lead-pins. A method is then described for stacking and mounting a plurality of semiconductor packages on a wiring substrate by first vertically positioning lead-pins on a wiring substrate and then passing these lead-pins through the holes in the semiconductor packages.

摘要:
A ferroelectric liquid crystal device (81) has transparent plates (83a, 83b), on which transparent electrodes (85a, 85b) are formed, arranged opposed to each other to form a space therebetween, with ferroelectric liquid crystals (95) sealed in the space. Black masks (89b) are arranged between the transparent electrodes (85b). Portions of the black masks (89b) extend over the transparent electrodes (85b). Black masks (89a) are arranged between the transparent electrodes (85a), with portions of the black masks (89a) extending over the transparent electrodes (85a). Since black masks (89a, 89b) are provided between the transparent electrodes (85a, 85b), respectively, state of display can be made uniform in non-pixel portions. Since the black masks (89a, 89b) on the transparent electrodes (85a, 85b) prevents undesired inversion of spontaneous polarization of the liquid crystal molecules in the pixel portions, the state of display of the pixel portions can be made stable.
