Title: Detecting device for line of sight
Inventor: KONISHI KAZUKI
IPC: A61B3/14
Filed: 1988-09-16
Abstract: PURPOSE:To correctly detect the line of sight direction even if an eyepiece section and an eye under test are not matched correctly by calculating the rotating angle of the line of sight and the relative displacement quantity between this device and the eye under test and determining the line of sight direction of the eye under test based on the calculated results. CONSTITUTION:An eye under test 3 is biased by the displacement quantity S, and the line of sight is directed in the direction of the angle theta. If the coordinates of the iris contour at the rotating angle theta and the displacement quantity S are set to (X1, Y1), (X2, Y2) and the image formation positions on a sensor are set to (-f, K1), (-f, K2), -f:X1= K1:Y1, -f:X2:K2:Y2, thereby K1 and K2 are expressed as shown in the equation (1). Personal errors of these quantities can be practically referred as constants, (b), (c), (l), (gamma), and (a) are referred as constants, the equation (1) is simultaneous equations on and S, thus thetaand S can be determined by resolving the equation (1). The solutions are determined, the coordinates of the right end and the left end of the iris contour are determined by an image sensor, then the rotation quantity and the displacement quantity of an eyeball, i.e., the direction of the line of sight, can be correctly determined.

IPC: B29D11/00
Filed: 1984-11-07
Abstract: PURPOSE:To obtain highly accurate plastic optical parts by forming the cross section of a lense molding into a shape inversely proportional to the variation in thickness in the optical axis direction along the radial direction of a lense having a longitudinally sectional form. CONSTITUTION:The cross sectional shape of a gate 8 is set up such that inversely proportional relation for variation in thickness along the radial direction of cross sectional shape including the axes of cavities 4 and 5 is formed. A molten resin is cast through a sprue 6, a runner 7, and a gate 8 into cavities 4 and 5 where the difference in the flow rates of the molten resin is counterbalanced by faster flows of resin passing through the gate 8 on both sides than the central part. The molten resin can thus be uniformely cast into the cavities 4 and 5 to supperss the occurrence of strain and thereby of residual stress. Since the welding of resins of difference temperatures due to nonuniform flow of the resin in the cavities can be prevented, teh occurrence of optical defects such as double refraction, etc., can be avoided, and high-quality lens can be obtained.

IPC: H02P27/08
Filed: 1982-12-22
Abstract: PURPOSE:To enable speed detection by using the output of a resolver by processing each of the sine wave voltage output and cosine wave voltage output of the resolver via a differentiating circuit, multiplier, a difference circuit, and a low pass filter. CONSTITUTION:The sine wave voltage ea and cosine wave voltage eb outputted from a resolver are differentiated respectively in differentiating circuits 104a, 104b, to outputs eat, ebt.

The difference Er between the outputs Ea and EB is determined by an adder 104, and an output Er is obtd. When the difference output Er is passed through a low pass filter 104f, it is cut of the high frequency component sin<2>wt and a DC component is obtd.; therefore, an actual speed voltage TSA is outputted and is fed to an arithmetic circuit. The speed detection is thus made possible by using the output of the resolver.
