Title: Intermittent blowout type wind tunnel testing device
Inventor: YAMAMOTO TAKAYUKI
IPC: G01L5/16
Filed: 1987-11-19
Abstract: PURPOSE:To reduce a vibration load placed on a wind channel balance when a shock wave passes by projecting a lock pin in a sting when the wind channel is actuated, and fixing a model to be tested. CONSTITUTION:The model 1 to be tested which is placed at a measurement part has aerodynamic characteristics measured under specific conditions by the wind tunnel balance 2 inserted into the model 1 to be measured. When the wind channel 1 is actuated, the lock pin 5 is protruded from the sting 3 and the model 1 to be tested is fixed. When a stationary measurement is taken after the shock wave passes, an accurate measurement can not be taken if the model 1 to be tested is fixed, so the lock pin is pulled in the sting 3. Thus, the model to be tested is fixed with the lock pin when the shock wave passes at the time of the wind channel actuation to reduce the vibration load placed on the wind channel balance inserted into the model to be tested when the shock wave passes.

Title: Method for correcting defective pixel in liquid crystal display device
Inventor: INOUE MASAMI
IPC: G02F1/1333
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To surely correct only a defective pixel without exerting adverse effect to adjacent pixels. SOLUTION: The liquid crystal(LC) display device for displaying a picture by using plural pixels arrayed like a matrix is constituted of a pair of substrates 2, 3, an LC layer 4 arranged between the substrates 2, 3, display electrodes 5, 6 arranged in each of the pixels, and TFT elements arranged in each of the pixels on the LC layer side of the substrate 5a. The LC layer side electrodes 5 on the insulating substrate 3 are functioned also as reflection plates. The light reflection electrode 5 of a defective pixel is irradiated with a laser beam of which wavelength and energy quantity are adjusted, so that the surface of the defective pixel is roughened, blacked or removed and the reflection of incident light to an incident direction is suppressed to correct the defective pixel.  Since an optical reflection electrode 5 of each pixel is corrected, the display quality of adjacent pixels is not reduced and defective pixels in a device requiring no orientation film can be also corrected.
