Title: Thin-film transistor, its manufacture, and liquid crystal display device
Inventor: KAWAMURA SHINICHI
IPC: H01L21/336
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a thin-film transistor whose drive characteristic is improved. SOLUTION: An area near an end part of a semiconductor active layer 25 is made thicker than a central part and a peripheral part of a gate electrode 39. Since a resistance of an end part of the semiconductor active layer 25 is high as compared to that of a central part, so that a gate voltage of a large generated amount of hot carriers relaxes an electric field near an ohmic contact region 27 at a drain side near a threshold voltage, electric field distribution expands to an end part of the semiconductor active layer 25. Electric field applied concentratedly to a drain junction part, which is a junction part of the semiconductor active layer 25 and the ohmic content region 27, is relaxed and characteristic shift and breakdown are restrained.  Since there is not need for forming an LDD region, the number of processes is not increased, and a resistance valve which is not high as compared to gate offset through a resistance of an end part of the semiconductor active layer 25 below an end part of the gate electrode 39 is high, when compared to that of a central part. A resistance value of an end part lowers as a voltage applied to the gate electrode 39 increases, thus restraining lowering of the drive capability of the thin-film transistor 44.

Title: Ultraviolet emission electroluminescent element and its manufacture
Inventor: MITAMURA SATOSHI
IPC: H05B33/14
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To stably radiate electromagnetic waves having a wavelength of 400 nm or shorter with stable luminance for a long time. SOLUTION: This element is provided with an ultraviolet emission film 4 formed from a nitride of a group 3B element, and a pair of conductive films 3, 5 formed on both the surface of the ultraviolet emission film 4 in a form interposing it. The ultraviolet emission film 4 radiates an electromagnetic wave having a wavelength 400 nm or shorter by applying electric field to the pair of conductive films 3, 5. Since the nitride of a group 3B element used for the ultraviolet emission film as a base material is a chemically stable compound, the element is not deteriorated by the moisture or carbon dioxide in the atmosphere, even under a strong electric field or exposure to an ultraviolet-ray and can hence maintain stable luminance over a long time.

Title: Encoder with monitoring function
Inventor: YAMASHITA MAMORU
IPC: H03M1/24
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To obtain an encoder in which the accuracy between respective waveforms can be measured automatically by a method wherein a measuring signal at a frequency higher than the cycle of an output signal is generated and the positional relationship between an output signal, on one side, to be used as a reference for a measurement and an output signal, on the other side, to be measured is measured by the signal. SOLUTION: A measuring-signal generation means 5 supplies, from a code plate 1, pulse signals CKL, CKR, CKC at a sufficiently high frequency to respective signal waveforms in such a way that their phases are deviated slightly (e.g. by 1/3 cycle). A measuring means 4 measures the interval between waveforms of respective output signals from the code plate 1 by using the signals from the means 5. For example, the interval between a phase difference signal D1a (a signal on the other side) and a phase difference signal D1b (a signal one one side) which are generated by the code plate 1 and a waveform shaping means 2 is confirmed by a counting operation by using a counter 42 for the pulse signal CKC. In the same manner, regarding respective signals from an encoder, a phase difference or the is measured while they are used as signals on one side and as those on the other side.  In this way, the accuracy between respective waveforms can be measured automatically without relying on a visual inspection, and the operating efficiency of an encoder can be enhanced.
