  • Patent number: 5696633
    Abstract: A varifocal lens is disclosed that includes, in order front to rear, a first lens group having an overall negative focal length and a second lens group having an overall positive focal length. The first and second lens groups are axially separated by a space that changes as the focal length of the varifocal lens is changed. The first lens group comprises, in order from front to rear, a biconcave lens element and a positive lens element. The second lens group comprises, in order from front to rear, a front subgroup and a rear subgroup. The front subgroup comprises, in order from front to rear, a first positive lens element, a first cemented lens, a second cemented lens having positive refractive power, and a second positive lens element. The rear subgroup comprises, in order from front to rear, a negative lens element, a positive lens element, and a negative meniscus lens element having a convex face oriented rearwardly. The varifocal lens fulfills the conditions:0.8<.vertline.fb/fa.vertline.<1.70.5<.

  • Patent number: 4091357
    Abstract: In a telemeter system using a measuring probe for radiating a sound pulse signal the pulse spacing of which corresponds to information to be measured such as temperature or salinity of various depths in the ocean water, in order to prevent the echo noise signal there is provided an improved receiving system which comprises a one-bit delay circuit, a pair of integrating circuits, a pulse generator and a gate. One of the integrating circuits is controlled by the signal as received and the other is controlled by a one-bit delayed signal derived from the received signal. The pulse generator generates a pulse signal having a predetermined time duration at a predetermined level of the output from the integrating circuit, and that pulse drives the gate, so as to eliminate the echo unexpectedly received during the pulse spacing.
