Abstract: PURPOSE:To make the measurement of eccentricity of all spherical surfaces possible by providing an auxiliary lens between an objective lens and a measuring table, and making the spacing between this auxiliary lens and the measuring table variable. CONSTITUTION:An auxiliary lens 21a is provided between an objective lens 16 and a lens 18a to be measured. The surface to be measured of the lens 18 is a concave surface and the radius of curvature thereof is relatively small. In correspondence to this, the auxiliary lens 21a is a concave lens.

Thereupon, the focal position of the lens 18 is so adjusted as to align to the central position a2 of the apparent curvature of the lens 18a by moving the lens 21a in the optical axis direction. By this, the pattern of a chart 13 is passed through the lenses 15, 16, and the auxiliary lens 21a, is reflected by the spherical surface of the lens 18a, again passes through the lens 21a and is imaged on the center a2 of the apparent curvature of the lens 18a.

Title: Inspection apparatus of pattern defect
Inventor: INOUE HIROSHI
IPC: G06T7/00
Filed: 1991-03-28
Abstract: PURPOSE:To accurately detect only a pattern defect singly, to enhance the detection accuracy of the defect and to enhance the reliability of the title apparatus by a method wherein whether the defect exists or not is judged by using the difference between the differentiated value of picture-element data of an object to be inspected and the maximum value of the differentiated value of picture-element data existing around corresponding picture-element data inside a reference image data. CONSTITUTION:In this apparatus, a subtraction circuit 24 subtracts a maximum differentiated value which has been selected in a second selector from a differentiated value selected in a first selector 4a, and sends the difference to a negative-value cancellation circuit 25. Only when the difference is a negative value, the negative-value cancellation circuit 25 replaces it with 0 and sends it to a judgment circuit 26. When the difference exceeds a preset threshold value, the judgment circuit 26 judges that a picture element data corresponding to the difference is a pattern defect. Consequently, even when coordinates are displaced a little between the inspected picture-element data and a reference image data, only the pattern defect can be detected accurately and simply.

Title: Method for evalulating maturity of liquor
Inventor: HIOKA KATSUYA
IPC: G01R33/44
Filed: 1985-03-29
Abstract: PURPOSE:To make possible the quantitative evaluation of maturity of liquor by measuring the nuclear magnetic resonance spectrum of the hydrogen nucleus of the liquor and making use of the decrease in the spacing between the peak of OH of water and the peak of OH of ethanol in the spectrum on progression of maturing. CONSTITUTION:The nuclear magnetic resonace spectrum of the hydrogen nucleus of the liquor is measured by using a nuclear magnetic resonance spectrometer. The exchange speed of the hydrogen nucleus of the water and ethanol is low with the freshly brewn liquor and therefore the peaks of the OH of the water and the OH to the ethanol are spaced from each other but as the maturing progresses, the exchange speed of the hydrogen nucleus increases and the peaks of the OH of both the water and alcohol are made non-discrimiminatable until finally both peaks overlap on each other. The spacing between the peak Pw of the OH of the water and the peak Pe of the ethanol is measured and the quantitative and objective evaluation of the maturity of the liquor is made possible.

Title: Inertia travel device of automobile
Inventor: BAN ITSUKI
IPC: F16D15/00
Filed: 1993-02-17
Abstract: PURPOSE:To secure such a device as reducing the consumption of fuel and power for an automobile using liquid fuel or battery power sharply. CONSTITUTION:A first turning shaft 9 using an output shaft as an input is installed there, and when it is normally rotated, a second turning shaft 7 is driven in the same direction via a one-way conical roller bearing clutch, and thereby an automobile is traveled by the driving torque. A travel speed is controllable by means of an operating angle of an accelerator pedal. When this pedal is reset and rotational speed in a driving source goes down, a driving wheel alone is freely rotated by action of the one-way conical roller bearing clutch and thus inertia traveling takes place. When a brake pedal is operated, the clutch is converted into a two-wat clutch, and engine braking or regenerative braking is operated, and this travel mode is continued as it is. When the accelerator pedal is operated, the travel mode is automatically released, and it is thus converted into an inertia traveling mode.
