A fluid-filled vibration damping device including, an elastic body and a flexible diaphragm is divided by a partition member in to pressure-receiving and an equilibrium chambers communicating with each other through a first and second orifice passages. The second orifice passage includes a pair of split passages formed at respective circumferential positions of the partition member and is open at its first open end in the pressure-receiving chamber and at is its second open end located in the central portion of the partition member in the equilibrium chamber. A pair of movable members disposed in diametrically-opposite portions radially inward of the split passages. Each movable member is displaceable based on a pressure difference between a fluid pressure in the pressure-receiving chamber, and a fluid pressure in the equilibrium chamber applied to the other surface of the movable member. An actuator disposed below the flexible diaphragm remote from the equilibrium chamber and is operable to displace the flexible diaphragm, for inhibiting and permitting said fluid communication through the second orifice passage.

In a camera body section of a camera according to the present invention, a cartridge chamber unit and a spool chamber unit are located on a lower connecting member with a lens barrel unit as a central unit. Furthermore, a driving-force transfer mechanism is located under the lower connecting member. An output of a driving motor located inside the spool chamber is transferred to the lens barrel unit, cartridge chamber unit, and spool chamber unit through a driving-force transfer mechanism by changing the unit receiving the output. In particular, the driven sections of the lens barrel unit and cartridge chamber unit are driven through a worm gear. According to this camera, it requires a minimum change of each unit section to accommodate a specification change and/or a model change. In addition, it is easy to perform partial assembly of every unit.

A camera comprises a fixed lens barrel including a moving lens barrel moveable to a collapsed position for non-photography and to a thrust position for photography, and a lens cover capable of pivoting with support shafts, which lie parallel to a plane substantially perpendicular to the optical axis of a photography lens, as a center so as to move to a closed position at which at least part of the face of the photography lens is shielded and to an open position at which the face of the photography lens is exposed. When the lens cover is open, if an external force is applied in a direction in which the lens cover is further opened, the lens cover separates from the support shafts. The support shafts are formed with two shaft members whose distal portions are formed with tapered surfaces and which are constrained to move in directions in which they are separated from each other.

A method for manufacturing a semiconductor device is disclosed herein by which the contamination of an epitaxial film-Si substrate interface with carbon can be solved without allowing boron to remain in the epitaxial film-Si substrate interface. The method for manufacturing a semiconductor device according to the present invention comprises a step of ion-implanting, into an Si substrate, an element or a compound which easily reacts with carbon, a step of removing a natural oxide film on the Si substrate, a step of annealing, at a temperature of 800.degree. C. or less in a CVD device, the Si substrate which has been subjected to the ion-implantation and the removal of the natural oxide film by the above two steps, and a step of carrying out an Si epitaxial growth or an Si.sub.1-x Ge.sub.x epitaxial growth on the annealed substrate by the CVD device.
摘要:
A camera in which a photographing lens tube is movable between a collapsed position assumed in a non-photographing condition and an extension position assumed in a photographing condition. The camera is provided with a barrier swingingly rotatable through a hinge between a fully closed position at which the barrier covers a front surface section of a photographing lens and further to take a fully open position at which the barrier retreats from the photographing lens. The barrier is biased in a closing direction when it is in a fully closed position side relative to a substantially middle position between the fully closed position and the fully open position, while being biased in an open direction when being in a fully opening position side with respect to the substantial middle position. With a power switch being switched from its OFF state to its ON state, the barrier is shifted from the fully closed position to the fully open position in conjunction with the movement of the photographing lens tube from the collapsed position to the extension position.
