Title: Exposure device of motion-picture camera
Inventor: SEKINE JIROU
IPC: G03B17/42
Filed: 1979-11-14
Abstract: PURPOSE: To miniaturize an exposure device by controlling the opening of an optical path by an plate-shaped shutter blind by adjusting the stroke length according to the brightness of an object.  
     CONSTITUTION: When the brightness of an object is high, angle (α) between lengthwise axes of lever 16 and shutter blade 3 is set relatively small through lever 21 with the exposure meter coupled and when cam 122 coupling with the film claw rotates by 180°, blade 3 oscillates with small strokes through pin 10 forming the cam follower. Consequently, the function of the optical path of optical system 1 by blane 3 is small in area. Similar shutter blane 4 also operates symmetrically to blane 3. When the brightness is low, on the other hand, initial positions of blanes 3 and 4 by lever 16 are shifted and the opening area increases through long-stroke oscillation. This constitution permits blades 3 and 4 to function as aperture 7 and the shutter at the same time, so that the need for a large discoid shutter will be eliminated.

Title: Method of detecting leak from liquid conveyance pipeline
Inventor: KOSUGI SANAI
IPC: F17D5/02
Filed: 1983-08-11
Abstract: PURPOSE:To eliminate an error which would result from the difference between the measured length of each pipeline section and its hydraulic length, and to prevent a detection performance fall which would result from the comparison of adjacent sections, by calculating the ratio between the pressure differences of two unadjacent sections, and comparing the ratio with that between the same sections which is previously measured when there is no leak. CONSTITUTION:A liquid conveyance pipeline 1 is divided into optional sections (i), whose pressure differences DELTApi are measured. The ratio (r) between the pressure differences of two unadjacent sections is calculated. The ratio (r) is compared with that (r0) between the same sections, which is previously measured when there is no leak. When a relation r-r0>epsilonr0, where epsilon denotes a differential coefficient for allowing a measurement error, is found out, it is judged that there is a leak between the two sections. According to this constitution, an error which would result from the difference between the measured length of the sections and their hydraulic length is eliminated, and a detection performance fall which would result from the comparison of adjacent sections is prevented.

Abstract: PURPOSE:To adjust a die temperature to an optimal level instantaneously by detecting a transfer displacement in a movable die and controlling a die temperature with a heating and cooling controller after comparing gelation timing and curing timing with a standard value with an arithmetic apparatus. CONSTITUTION:Displacement of movable die 5 is sensed by a detector 9a and then is processed by a displacement meter 9b. After this process, gelation timing GT and curing timing CT obtained by twice differenting the processed data with an arithmetic apparatus are compared with standard gelation time and curing time. If GT and CT are less than the standard time, a signal e to reduce temperature in the die 3, 5 is output to a heating and cooling controller 14. If GT and CT are greater than the standard time, a signal f, to raise the temperature in the die 3, 5 is output to the heating and cooling controller 14. Thus the temperature of the die 3, 5 is adjusted to an optimal heating level.

Abstract: PURPOSE:To reduce the thickness of the display device itself which enlarges and projects an image of a liquid crystal display panel on a screen and to eliminate the out of focus. CONSTITUTION:The image of the liquid crystal display panel 11 is divided into plural parts through corresponding convex lenses 23a, 23b, and 23c. In this case, the image is only divided in plural, so the convex lenses 23a, 23b, and 23c can greatly be shortened in focal length. The respective images divided by the convex lenses 23a, 23b, and 23c are diverged by one concave lens 24, and enlarged and projected on the screen 25. The distance from the convex lenses 23a, 23b, and 23c to the screen 25 is therefore shortened very much to make the device thin. Further, optical path differences are adjusted with differences in focal length among the convex lenses 23a, 23b, and 23c through an optical path difference adjusting plate 26 which is provided on the left surface of the screen 25, and consequently the out of focus is eliminated.
