Title: Distance measuring apparatus
IPC: G01S7/487
Filed: 1989-02-10
Abstract: In a distance measuring apparatus for optically detecting a distance to an object (4) by using a triangulation method, two signals which are obtained from a position sensitive device (6) are added and it is detected that the result of the addition has exceeded a predetermined threshold level. On the other hand, it is assumed that a signal waveform to drive a light emitting device (1) is a signal whose level increases with an elapse of time. When the addition result exceeds the threshold level, the level of the drive signal is held constant. At this time, by dividing a signal obtained from the position sensitive device by the signal indicative of the addition result, a signal relating to the distance to the object is obtained.

Abstract: A disk substrate (29) is supported by a support 
base (27) formed on a center pin (11) which is 
vertically movable on a selective basis, a table (17) is 
set below the disk substrate, and a stamper (18) is 
positioned on the table by means of a guide ring or the 
like. A ring-shaped portion of resin (36) which is 
cured upon radiation of ultraviolet rays is set on the 
stamper. The center pin is then caused to descend, by 
means of a drive mechanism (25), to a first position, at 
which position the disk substrate is on the point of 
contact with the resin. Then, the disk substrate is 
caused to descend intermittently in units of very small 
amounts, to a second position, at which position the 
entire periphery of the ring-like resin is brought into 
contact with the disk substrate. From the second 
position, the disk substrate is made of descend by means 
of the load of a weight while, at the same time, the 
ring-shaped portion of resin is drawn by vacuum suction 
from its central position, thereby forming on the 
surface of the stamper a resin layer (41) on which a 
record, formed on the stamper, is imprinted.

Abstract: A method of and system for automatically determining 
length, attenuation, impedance and existence of 
bridge taps on installed communication cable having 
access to only one end of the cable. A waveform, 
which includes incident and reflected pulses, is 
analyzed to determines the presence of significant
