Abstract: PURPOSE:To provide the secondary imaging type finder optical system which enables an observer to observe a good object image free from eclipse over the entire variable magnification range by suppressing the change in the observer's pupil position due to a fluctuation in the position of the exit pupil according to variable magnification. CONSTITUTION:This secondary imaging type finder optical system is constituted to form the object image formed near a first imaging plane 2 by an objective lens system 1 having a variable magnification section on a second imaging plane 6 via a first field lens 3 and an erector lens 6 and to let the observer observe the object image on the second imaging plane 6 via an eyepiece lens 8. The fluctuation in the exit pupil position following the variable magnification of the objective lens system 1 is suppressed to a lower level by moving at least a part of the lenses of the erector lens 5 on the optical axis.

Title: Digital control camera
Inventor: HARADA TOSHIMITSU
IPC: G03B17/00
Filed: 1979-05-24
Abstract: PURPOSE: To achieve the simplification of mechanisn and the improvement of endurance by detecting and controlling the respective displacement positions of the plural moving members which displace at different timings time-serially respectively as digital signals by one digital signal generator.  
     CONSTITUTION: When a main switch S1 is turned ON, an A/D circuit AD outputs the specified digital information to an aperture information circuit FR and shutter second time information recording circuit TR, respectively. When a release switch S2 is turned ON in this state, a central control circuit CC lets the operation of a pulse counting circuit FC and the movement of an aperture driving member be started. A digital comparator DC compares the counter pulse information of the FC and the aperture value information of the FR and when they coincide, it stops the driving member, by which the aperture is determined. The central control circuit CC sends the start signal to the second time control circuit TC, whereby correct exposure is done. Thereafter, the resetting of the aperture driving member and shutter followed by winding of film are accomplished by a motor control circuit MC.

Abstract: PURPOSE:To improve the heat transfer performance as well as the performance of a liquid-liquid type heat exchanger and miniaturize the same by a method wherein the ratio of the pitch of fins in the axial direction of a tube to the inner diameter of the tube as well as the width of a spiral groove in the fins at a position corresponding to the 1/2 of the depth of the same are designed so as to be less than specified values. CONSTITUTION:The ratio P/Di of the pitch P of fins 4 in the axial direction of a tube to the inner diameter Di of the tube is designed so as to be less than 1 (one) while the width S of a spiral groove 6, opened to the inside of the tube, at a position corresponding to the 1/2 of the depth of the groove 6 is designed so as to be less than 1mm. When both of the ratio P/Di and the width S of the spiral groove are too small, there is a possibility that the heat transfer performance is rather reduced than improved and, therefore, the ratio P/Di is preferably designed so as to be more than 0.5 while the width S of the groove is desirable to be designed so as to be more than 0.5mm.
