Title: Ecl frequency dividing circuit
Inventor: ISHII HIDEKAZU
IPC: H03K3/286
Filed: 1990-03-27
Abstract: PURPOSE:To suppress self-oscillation specific to a frequency dividing circuit while the difference of an input DC offset current is minimized by selecting the size of the emitter of a transistor(TR) through which a current for a slave amplifier is supplied to the size of a multiple of (GO+1)/(GO-1) of the TR of a master amplifier or above. CONSTITUTION:The size of the emitter of a TR through which a current for a slave amplifier is supplied in a middle-stage input clock amplifier stage is set to the size of a TR of a master amplifier of middle-stage input clock amplifier stage as a multiple of (GO+1)/(GO-1) (GO is a DC gain of a data amplifier). Thus, the free-run operation of a frequency dividing circuit is suppressed without increasing number of components while the deterioration in the minimum input sensitivity and of the highest operating frequency characteristic is minimized.

Abstract: PROBLEM TO BE SOLVED: To detect a view point position, attitude of a simple camera outdoor by calculating a position attitude deciding parameter based on the corresponding relationship between marks in an image and a known mark of a world coordinate value. SOLUTION: For example, a coordinate detecting module 200 of a buried material simulator detects a coordinate position of the center of gravity in an image coordinate system of three manholes Q1, Q2 and Q3. A depth estimating module 100 detects a depth in a world coordinate system of the center of gravity of three manholes based on a position of the center of gravity of the respective manholes in an image coordinate system and a position of the center of gravity in a known world coordinate system. The depth of the each manhole is obtained based on a diameter of the manhole in the world coordinate system, number of pixels displaying a diameter of the manhole in the image coordinate system, a focal distance of the camera, and a length corresponding to the one pixel of the camera.  To exhibit a virtual image of a gas tube or the like buried in the ground for a used of an HMD device, it is necessary to accurately align its ground position with a view point position (camera parameter) of the camera. A parameter estimating module 300 estimates the camera parameter.

In connecting the terminals 51, 53, the current made flowing to the diodes D43, D44 is smaller than the current at the transmission state and the coupling between the terminals 1, 3 approaches more than the open state at the transmission. When the terminals 51, 54 are connected, no current flows to the diodes D43, D44 to maximum the coupling quantity between the terminals 1 and 3.
