Title: Semiconductor nonvolatile memory device
Inventor: MASAKI TORU
IPC: G11C16/02
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To enable effective writing even if the write characteristic is changed to reduce the write time by determining whether the threshold value of an electrical programmable nonvolatile memory cell is identical to the reference potential or not and then controlling the write voltage depending on the result of determination. SOLUTION: A high voltage VPP is input to a voltage boosting circuit 104. Depending on the data DL which has been initialized in a determination circuit 2 and read to a selecting circuit 6, the lowest write voltage WV5 is selected from the write voltages WV 1 to 5 and it is then impressed to a control gate of memory cell 3 for the purpose of data writing. A determination reference voltage VV is applied to the control gate of the memory cell 3 and a current across the drain and source is converted to the data DL via the current - voltage converting circuit 9 and A/D converter 8. When the data DL is read and the threshold value of memory cell 3 has not reached the write determination reference voltage VV, the higher write voltage WV 1 to 4 is selected and this selection is repeated.

Filed: 1989-10-25
Abstract: PURPOSE:To perform exact detection at all times by providing a state quantity correcting means which corrects a state quantity detected from the previously stored relation between a vehicle state quantity and curvature and correcting an error due to a travel road shape. CONSTITUTION:Two guide lines 12 and 14 are extracted from an image obtained by a camera A and tangents at two points of the two guide lines 12 and 13 at different distances from a vehicle 10, i.e. four tangents are detected by a tangent detecting means C. Then the lateral displacement or yaw angle of the vehicle is detected from the two tangents of the guide lines 12 and 13, obtained by the tangent detecting means C, at the same distance from the vehicle 10 and the curvature of the same guide line is calculated E from the inclination distance between the tangents differing in the distance from the vehicle. Here, the lateral displacement or yaw angle of the vehicle and the curvature of the travel path are in constant relation, which is stored previously in a storage means F to correct the detected state quantity according to the previously stored relation. Consequently, the vehicle state quantity can be corrected with the curvature of the travel path and invariably exact detection becomes possible.

Title: Optical device
Inventor: WADA FUMIO
IPC: G02B27/28
Filed: 1985-12-11
Abstract: PURPOSE:To eliminate polarization dependency by arranging a birefringence plate in an optical path and also arranging a 1/4-wavelength plate right behind it. CONSTITUTION:A light wave 3 entering an optical device is incident on the incidence surface of the birefringence plate 1 at a 0 deg. angle of incidence, and the polarized component S wave perpendicular to the incidence surface ravels straight (3A) and is transmitted through the 1/4-wavelength plate 2 to travel while coinciding with the axis of the light wave 3. The polarized component P wave of the light wave 3 which is parallel to the incidence surface is refracted abnormally (3B) and passes through the birefringence plate 1, and the light is refracted by a projection surface in parallel to the axis of the light wave 3 and passed through the 1/4-wavelength plate 2 to travel in parallel to the axis of the light wave 3. The P and S waves shift in phase by a quarter as much as the wavelength when passing through the 1/4-wavelength plate 2, so the light projected from the 1/4-wavelength plate 2 is circularly polarized light. This is therefore equivalent to random polarized light apparatently and characteristic variation (polarization dependency) of the degree of optical coupling, transmission loss, and transmission waveform, etc., is eliminated, thereby facilitating the design of an optical device.

IPC: G01N27/28
Filed: 1992-10-16
Abstract: PURPOSE:To measure even a sample in a very small amount with good accuracy and to reduce an error by a disturbing substance such as a protein or the like by a method wherein a filtrate layer and/or a liquid-holding layer are formed on a measuring electrode or on an electrode system including the measuring electrode. CONSTITUTION:A copper-clad glass substrate 1 is etched, and a measuring electrode 3 and a counter electrode 2 are formed. The measuring pole 3 or the measuring pole 3 and the counter electrode 2 are covered with a filtrate layer and/or a liquid-holding layer. When the liquid-holding layer is formed, an influence by a flow rate is reduced and even a sample in an extremely small amount can be measured. In addition, when the filtrate layer is formed, it is possible to reduce an error by a disturbing substance in a living-body sample. In addition, since blood whose viscosity is high is made to reach an enzyme-fixing film and it is measured quickly, an anti-blood coagulant is carried and held in at least one layer out of the filtrate layer and the liquid-holding layer. In addition, a compensation electrode to which an enzyme is not fixed is formed, an influence by the adsorption of a protein or the like in a sample or by a subreaction is removed and a higheraccuracy measurement can be performed.

Abstract: PURPOSE:To control the diffusion of oxidizing agent into a part beneath a nitride film and to reduce the region of an oxide film by depositing the nitride film through which the oxidizing agent hardly passes on the side wall of a hole part that forms a silicon oxide film, using the film as a mask, and applying a selective oxidizing method, at an opening part for forming a silicon oxide film. CONSTITUTION:A hole part 16 is selectively formed in an oxide film 12 and a first nitride film 13 which are deposited on a semiconductor substrate 11. A second nitride film 14 is deposited on the entire surface including the hole part 16. Then, anisotropic etching is performed for the second nitride film 14, and the upper surfaces of the semiconductor substrate 11 and the first nitride film 13 are exposed. A silicon nitride film (LOCOS) 17 is grown in the hole part 16 by high pressure oxidation. The film 17 is removed by wet etching having selectivity. Then, a recess part 18 is formed in the semiconductor substrate 11 directly beneath the hole part 16. Then, the high- pressure oxidation is performed again, and regenerated LOCOS 20 is grown in the recess part 18 in the semiconductor substrate 11. Thus, the lateral oxidation (bird's beak) 19 of the oxide film 12 on the semiconductor substrate 11 is suppressed with the second nitride film 14.
