Filed: 1995-02-01
Abstract: PURPOSE: To reduce time up to completion of alignment as well as making the permissible range of alignment constant, by changing sensitivity of alignment detecting system based on reflective light amount of a tested eye. CONSTITUTION: A ring-shaped mark P as well as an anterior part image of eye Ef are displayed on a monitor M by lighting plural LED 11-31. Rough alignment is performed by moving a device body so that the ring-shaped mark P comes to a position of pupil image Ea. Furthermore, the device body is moved so that a luminescent point image Q due to lighting of the LED 31 enters into the ring-shaped mark P. Then, received light amount of an alignment light sensor 55 of an alignment detecting optical system 50 is increased. Thereby, alignment is judged to be completed when the received amount of light is above a standard value. On this occasion, luminous amount of the LED sensor 31 is controlled based on the received amount of the anterior part of eye reflecting light sensor 29.  Thereby, the range of alignment completion is always made constant irrespective of high or low reflectance of cornea C of the tested eye E.

Filed: 1990-01-25
Abstract: PURPOSE:To detect voltage with high sensitivity by interposing a medium having a dielectric constant higher than that of air between a part to be measured and the detection part arranged close to said part. CONSTITUTION:When a detection part is composed of an optical probe 10, the size thereof is pref. almost same as that of the electrode 22 of an object 20 to be measured. A total reflection mirror 16 is formed on the bottom surface of the probe 10 and a high dielectric constant medium 34 is interposed between the probe 10 and the object 20 to be measured.

Abstract: PURPOSE:To enable more accurate determination of a static weight value of an object of weighing, by providing a subtracting element which determines a value obtained by subtracting the static weight value determined by a first weight computing element from the static weight value determined by a second weight computing element. CONSTITUTION:When a horse, which is an object of weighing, is weighed, for instance, first a man as a guiding body guides the horse, with reins in his hand, onto the entrance side of a weigher 2 and the man gets ahead on the weigher 2 from a pedestal 1 and stops thereon. Then a first weight computing element S1 determines a static weight value of the guiding body from weighed value data sent from the weigher 2 while the guiding body alone is on the weigher 2. Next, a second weight computing element S2 determines a static weight value being the sum of the values of the guiding body and the object of weighing, from the weighed value data sent from the weigher 2 while the guiding body and the object of weighing are on the weigher 2. Then, a subtracting element S3 subtracts the static weight value determined by the first weight computing element S1 from the static weight value determined by the second weight computing element S2 and determines the static weight value only of the object of weighing.

Filed: 1986-01-29
Abstract: PURPOSE:To eliminate the electric coupling deteriorating the characteristic of the titled filter by adopting the constitution shielding the coupling pattern of a dielectric resonator between stages eliminating the dielectric resonator of an input/output stage.
