Title: Method for observing image of object and observing apparatus using the same
Inventor: INE HIDEKI
IPC: G02B17/08
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce deviation values of a reflection member and a convex lens by a method a reflection member is arranged in a unit integrated with a convex lens and an object is observed to correct effect due to changes in the attitude of the reflection member. SOLUTION: A pattern on a reticle R forms an image on a wafer W at an exposure wavelength by a projection optical system PL and the reflected light RL thereof enters a convex lens CVL through the optical system PL. The lens CVL is integrated with a prism P having a total reflection surface of a mirror TRM surface and the image of the wafer W is formed at the position I' at a distance L from the reflection surface of the mirror TRM. When the integrated unit is inclined by an angle θ under the vibration, an incident light beam is inclined by an angle θ the same as the angle θof the inclination of the mirror TRM.  This gives a deviation value Δ1 =Ltanθ attributed to the mirror TRM and a deviation value Δ2 =-L1 tanθ attributed to the lens LVC (wherein L1 represents a distance to the surface I' from the lens, -α angle of light beam inclined by parallel eccentricity of surface top) and the effect of the both is opposite in direction. That is, the effect is corrected by integrating the both to reduce the deviation values.

Title: Watthour meter
Inventor: GOTO HIDEKAZU
IPC: G01R22/00
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To precise calculate watthours with a limited register capacity by dividing watthours with a set threshold, making a reset each time when the quotient is obtained repeatedly obtaining watthours while taking the remainder as an initial, and adding the quotients repeatedly obtained together so as to obtain. SOLUTION: A voltage (v) and a current (I) delivered from terminals 11, 12 are normalized by input circuits 21, 22 and are converted into digital values by A/D converters 31, 32, and a momentary power w(n)=v(n).i(n) (where n is a sampling number) is obtained by a computing means 40 which also calculates an effective power W(n)=(1/n) Σw(n) from thus obtained momentary powers, and further, calculates a watthour Wh(n)=(1/k)Σw(n) (where k is 3600/a period obtaining watthour). Since the Σw(n) increases with the time, the watthour Wh(n) is divided by a certain threshold value so as to add the quotient so as to obtain a power value. With this arrangement, it is possible to prevent a computing register in the means 40 from being excessively increased.
