IPC: G02B7/28
Filed: 1991-01-08
Abstract: PURPOSE:To provide a visual axis detecting apparatus capable of detecting a visual axis with high accuracy by obtaining the positional coordinates of a first Purkinje image based on the reflected ray from one's eyeball and the pupil by the use of an image sensor to properly control the integrating time of the image sensor when the visual axis of one's eyeball is detected. CONSTITUTION:A light flux from a projector 7 is incident on one's eyeball, and the positional coordinate of a Purkinje image based on the reflected ray from the eyeball and that of the pupil are detected by a detecting means 4 having an image sensor 4a. When the visual axis of eyeball is obtained by the use of these positional coordinates detected by the detecting means 4, it is limited by utilizing data having the upper limit value of integrating time of the image sensor 4a stored previously in a memory means 2 and data of light measured by a photometric sensor for measuring the brightness near the front of eyeball.

Title: Frequency-voltage converter
Inventor: OOSONE TADASHI
IPC: H03K5/00
Filed: 1979-02-07
Abstract: PURPOSE: To increase both the responsiveness and the resolution of conversion by converting the intput frequency into the voltage after giving the n-multiplicatuon to the input frequency.  
     CONSTITUTION: Input signal f i  is turned into the n-fold frequency via frequency converter circuit 15, and this converted signal nf i  undergoes the D/A conversion with every period 1/f 0  to be delivered in the form of the voltage. Thus when thinking of output voltage ΔV to one unit of the pulse input, n-fold ΔV is obtained. Thus the D/A conversion can be accelerated by the amount equivalent to the shortened period TO of the input pulse. At the same time, output voltage ΔV can be truned to 1/n as long as the sampling period is constant, thus obtaining the higher output accuracy.

Filed: 1982-01-28
Abstract: PURPOSE:To prevent deterioration of precision in an enhanced density device by a method wherein conductor regions to be subjected to non-contact potential measurement by means of electron beam radiation is kept a prescribed distance from conductors with different potentials. CONSTITUTION:To measure the potential between leads 8 and 9, gaps d1-d8 should be not less than 4mum, in the vicinity of regions 10, 11 to be exposed to electron beam radiation. The region 10 is to be located at a spot separated not less than 4mum from other conductors in a conductive pattern designed in a conventional manner without considering the use of an electron beam to measure potential. The region 11, wherefore no such locations are available in a conventional designed as referred to above, and therefore to be positioned as indicated by broken lines, has a part of the conductor pattern extended for measurement with other conductors routed around. A semiconductor device of this design is less affected by nearby conductors in a non-contact potential measurement by means of electron beam radiation and never experiences an error serious enough to incapacitate a logic level decision or the like.
