Title: High variable power zoom lens including wide angle
Inventor: OGAWA RIYOUTA
IPC: G02B13/04
Filed: 1979-05-16
Abstract: PURPOSE: To obtain the compact high variable power zoom despite the use of a region where the movement of groups is large by moving the 1st group to the subject side and coupling the 2nd group and the 3rd group under simultaneous magnification thereby decreasing the fluctuations of aberrations.  
     CONSTITUTION: The lens consists of the 1st group G 1 , the 2nd group G 2  and the 3rd group G 3  of positive refractive powers disposed subsequently from the subject side. For Wide→Tele, the 1st group G 1  and the 3rd group G 3  move integrally to the subject side. The 2nd group moves separately from these. In order to decrease aberration fluctuations by using a region of larger movement of the groups, the 2nd group G 2  uses the AB region which becomes an equal magnification at the Tele end, and the 3rd group G 3  uses the BC region which becomes equal magnification at the Wide end. The 1st group G 1  is moved to the subject side, for Wide→Tele, so that the 2nd group G 2  and the 3rd group G 3  may be coupled under the simultaneous magnification. Since the aberration fluctuations are reduced in this way, the compact high variable power zoom system is obtained even if the region of large movement of te group is used.

Title: Phase locked oscillator
Inventor: SUZUKI SHINJI
IPC: H03L7/06
Filed: 1990-03-14
Abstract: PURPOSE:To offer an output frequency with high accuracy and the clock of a phase by varying the transmission characteristic of a phase locked oscillator when the interruption of an input signal is recovered, and shortening synchronous time. CONSTITUTION:When the input signal 100 is interrupted, a control circuit 9 stops a control signal 600 by an input interruption signal 300. The value of a VCO control voltage 500 is held at a value just before the interruption of input. When the interruption of the input signal 100 is recovered, or when the input signal 100 is inputted, a multiplier 10 converts the output of a low-pass filter converted to digital data to data multiplied by multiplication factor KA(KA>1) times until the phase of the input signal 100 is synchronized with that of a phase comparison signal 200 to set a loop gain at a high level at the time of acquisition of synchronism. Since the VCO control voltage 500 can be approximated to a voltage in which the change quantity of the output of the low-pass filter is multiplied by KA times, it is possible to shorten a time required for the synchronization of the phase locked oscillator.
