Title: Image display device
Inventor: OGAWA EIJI
IPC: H04N5/66
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To allow an image display device to display an image with a uniform gradation over the entire screen. SOLUTION: A gradation correction LUT 32 has a gradation correction lookup table for each area by which the gradation for areas dividing a display image by a prescribed number is almost uniform over the entire screen by correcting the gradation of image information S3. An image input means 10 receives an image signal SO and gives an image signal S1 to an image processing means 20 and a position detection means 34. The position detection means 34 detects a display position of the image signal S1 displayed on an image display means 40 and inputs position information S4 to the gradation correction LUT 32. The gradation correction LUT 32 uses the image processing means 20 to apply gradation correction to the image signal S2 subject to image processing based on the gradation correction lookup table of an area corresponding to the position information S4.  The image display means 40 displays the image based on the image information S3 subjected to gradation correction.

Title: Flash device capable of high-speed synchronizing
Inventor: HOSOMIZU HIROSHI
IPC: G03B15/05
Filed: 1988-10-06
Abstract: PURPOSE:To freely set a shutter speed and an aperture value and to enable desired flash synchronized photography by allowing a light emission part emit light intermittently with a selected pulse signal and varying the duty ratio of the flash light emission. CONSTITUTION:When the shutter of a camera is released, a control circuit 7 is put in operation and a control circuit 4 sends a trigger signal to a light emission control circuit 5. Further, a pulse is outputted from a terminal HSS of the circuit 4 and a high-speed synchronization mode is selected with a switch SW2. Then while the trigger signal is sent out, a pulse with a selected duty ratio is outputted and a flash discharge tube Xe emits light intermittently with the selected duty ratio. Then the quantity of the light emission is varied by varying the duty ratio and the output timing is further varied. Consequently, desired flash synchronized photography is performed by setting the shutter speed and aperture value freely.

Title: Semiconductor storage and its manufacture
Inventor: ASHIDA MOTOI
IPC: H01L21/8244
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a leakage current component by forming a first kind of MOS transistor containing a first impurity in a source/drain, a second kind of MOS transistor containing a second impurity, and a data storage node containing the first and the second impurities on a semiconductor substrate. SOLUTION: In a semiconductor storage, an N<-> region of a data storage node ND is formed by using a plurality of layers with different impurity, thus forming N<-> /P junction and hence preventing a depletion layer being formed by the N<-> /P junction from reaching a substrate surface when a normal bias is applied. Therefore, the leakage component of the leakage current of the N<-> /P junction can be greatly suppressed. In (b) indicating the impurity profile of the data storage node ND and the forming state of the depletion layer, upper and lower Figures show the state where bias is not applied and that where, for example, a bias of 3 V is applied, respectively. In this manner, even when the bias is applied, the depletion layer does not reach the surface.

Abstract: PURPOSE:To prevent a reduction in engine speed, by generating an idle-up command when an engine temperature is greater than a predetermined value at starting of an engine, and a predetermined condition permitting a secondary intake air to be supplied to the downstream of a throttle valve is not satisfied. CONSTITUTION:During operation of an engine, when an operational condition of the engine satisfies a predetermined condition, a control circuit 20 controls a linear type solenoid valve 6 according to an output signal from an oxygen sensor 14 and supplies a secondary intake air into an intake pipe 4 downstream of a throttle valve 3.

Filed: 1993-09-16
Abstract: PURPOSE:To obtain a TFT excellent in the characteristics, reliability, and yield under conditions by which a substrate material is not affected by rendering the thickness of a silicon film by a specific amount by oxidizing the silicon film to form an insulating film comprising silicon oxide as a chief ingredient on the surface of an active layer as a gate insulating film. CONSTITUTION:An amorphous silicon film with the thickness of 1500Angstrom  or smaller is formed, annealed for crystallization in line nitrogen atmosphere and patterned to form an island-shaped silicon film 103 (active layer of a TFT). Thereafter, the silicon film is rendered to a reaction with oxygen and hydrogen, particularly a pirogenic reaction or heating to 500-750 deg.C in an atmosphere containing water vapor, whereby the surface of the silicon film is oxidized to reduce the thickness of the silicon film by 50Angstrom or more. Thus, oxidized silicon film 104 with thickness of about 1000Angstrom  for example is formed. Then, the substrate is annealed to form a polycrystalline silicon film which is in turn patterned to form a gate electrode 105. Thus, contamination on the outermost surface of tire silicon film is prevented from reaching a silicon-silicon oxide interface owing to the foregoing oxidization.
