Abstract: The present invention relates to a thin film transistor device formed on an insulating substrate of a liquid crystal display device and others, a method of manufacturing the same, and a liquid crystal display device. In structure, there are provided the steps of forming a negative photoresist film on a first insulating film for covering a first island-like semiconductor film, forming a resist mask that has an opening portion in an inner region with respect to a periphery of the first island-like semiconductor film by exposing/developing the negative photoresist film from a back surface side of a transparent substrate, etching the first insulating film in the opening portion of the resist mask, forming a second insulating film for covering the first insulating film and a conductive film thereon, and forming a first gate electrode and a second gate electrode by patterning the conductive film.

Abstract: A respiration monitoring system monitors the state of disorder of the respiratory system of a sleeping patient based on the detection of respiratory body movement without the need of putting sensors directly on the patient's body. The system includes weight sensors that produce weight signals attributable to the patient's respiratory body movement. From weight signals having a frequency band of respiration, a respiratory body movement signal is produced, and the fall of blood oxygen saturation which occurs at obstructive apnea of the sleeping patient is determined based on the variation pattern of the amplitude of respiratory body movement signal. The occurrence and frequency of the fall of blood oxygen saturation are displayed on a display unit.

Abstract: In the fabrication of a CMOS-TFT, non-selectively doping (for both of p- and n-type TFTS) and selectively doping (only for the n-type TFT) with p-type impurities (B: boron) are successively performed at very low concentrations to control the threshold voltages (Vthp and Vthn). More specifically, the Id-Vg characteristics of the p- and n-type TFTs are initially negatively shifted. In this state, non-selectively doping is performed positively to shift the p- and n-type TFTs first to adjust the Vthp to a specified value. Selectively doping is then performed positively to shift only the n-type TFT to adjust the Vthn to a specified value. The threshold voltages of the p- and n-type TFTs constructing the CMOS-TFT can be independently and efficiently (with minimum photolithography) controlled with high accuracy.

Abstract: An infant condition monitoring system has a sensor sheet including uniformly arranged plural pressure sensitive load cells. An ECU in an electronic unit connected to the sensor sheet calculates an infant's breathing signal, sleeping posture and weight data. Those signal and data are converted into data signals to modulate a carrier signal thereby. A transmitter in the electronic unit transmits a radio signal resulting from the modulation. A monitoring unit is constructed to be carried by a care provider. A receiver in the monitoring unit demodulates the received radio signal. An ECU reproduces the data signals including the breathing signal, sleeping posture and weight data, and determines a respiration rate, sleeping posture and weight. A display displays the respiration rate, sleeping posture and weight, and a speaker produces an output sound in correspondence with the breathing signal.

Abstract: In an active matrix-type display device where scan bus lines (S.sub.i) and data bus lines (D.sub.j) are formed on different substrates, two kinds of scan bus lines (SP.sub.i, SN.sub.i) are provided. A first switching element (TFTN.sub.ij) is connected between a reference voltage supply line (V.sub.R) and a display electrode (E.sub.ij), and is controlled by a first scan bus line (SN.sub.i), and a second switching element (TFTP.sub.ij) is connected between the reference voltage supply bus line (V.sub.R) and the display electrode, and is controlled by a second scan bus line (SP.sub.i). The first switching element (TFTN.sub.ij) is turned ON by a positive or negative potential at the first scan bus line.

Abstract: An active matrix liquid crystal display apparatus comprises first and second substrates facing each other through a liquid crystal layer. The first substrate has a plurality of scan bus lines, thin film transistors, display electrodes, and reference potential supplying bus lines, and the second substrate has a plurality of stripe-like data bus lines that face the display electrodes. The display electrode has a compensation capacitor for compensating a potential fluctuation occurring in the display electrode after a gate electrode of the thin film transistor is selected. The capacitance of the compensation capacitor is larger during a compensation period than during a storage period in which the gate electrode of the corresponding thin film transistor is not selected.
