Title: Centrifugal impeller for centrifugal revolving fluid machine
Inventor: KANEMITSU YOICHI
IPC: F04D29/24
Filed: 1994-06-16
Abstract: PURPOSE:To prevent breakage due to fluidic exciting force by communicating a fluid guide hole installed on the suction side of the main plate of an impeller with a recess in the end face opposed to a side plate for the main plate to partially fix the radial inner edge of a disc covering the recess to the main plate. CONSTITUTION:A fluid guide hole 3 is open near a suction port 8a in a main plate 2 and communicated with an annular groove 5 in the end face opposed to a side plate 7 for the main plate 2 via a communication passage 4. The radial inner edge of a disc 9 covering the annular groove 5 is fixed to the main plate 2 at plural welding points 10. When an impeller A is revolved, pressure Pa in a room B partitioned with the annular groove 5 and the disc 9 is almost equal to pressure PA in the suction port 8a and pressure Pb outside the disc 9 is almost equal to pressure Pb in a discharge port 8b. As a result, the disc 9 is firmly pressed against the main plate 2 at a differential pressure DELTAP=Pb-Pa. In the case that the main plate 2 is vibrated with fluidic exciting force, vibration is excited to the disc 9 with the inner edge as a basic point because the outer edge is free. At this time, friction damping force reduces the vibration of the main plate 2 and prevents breakage.

Title: Camera shutter device
Inventor: KOBAYASHI KOICHI
IPC: G03B9/10
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To save power consumption during long exposure at a shutter device where the closing operation of an exposure aperture is executed by an electromagnetic release. SOLUTION: The exposure aperture is opened by descending a cam 2e by the pin 4b of a lever 4 when a member 2 travels leftward by the rotation of a motor pinion 1. Then, a magnet 8 is demagnetized and the lever 6 is rotated rightward, so that the exposure aperture is shielded. In the case of long time photographing, the magnet 8 is demagnetized after making the member 2 travel leftward until a cam edge 2i reaches the rightward rotation path of the pin 6b in the energizing state of the magnet 8, so that a device waits that desired long time passes. Then, when the member 2 travels rightward, the lever 6 is rotated rightward in descending the cam edge 2h by the pin 6b, so that the exposure aperture is shielded.  Thus, in the case of the long exposure, the device stands by for the most part of entire exposure time in the demagnetizing state of the magnet 8, so that the power consumption is saved.
