摘要： The forcal plane shutter for cameras is equipped with a first release lever capable of retaining a rear blade group at position to close an exposure aperture, and a second release lever capable of maintaining a front blade group and the rear blade group at the unfolded position thereof and the folded position thereof respectively until the front blade group and the rear blade group are attracted and retained at the unfolded position and the folded position respectively securely with an electromagnetic device. The focal plane shutter is of a double light interruption type which has excellent response to the release signal and capable of assuring stable operations. The focal plane shutter further comprises a control means capable of retaining the first release lever in the released state thereof and can be set in a successive photographing mode accordingly.

摘要： A method of refining carbon parts for the production of polycrystalline silicon, comprises the steps of, replacing an inside gas of a reactor, in which the carbon parts are placed, with an inert gas, drying the carbon parts by raising a temperature in the reactor to a drying temperature of the carbon parts while flowing an inert gas through the reactor, raising a temperature in the reactor to a purification temperature higher than the drying temperature while flowing chlorine gas through the reactor, reducing a pressure in the reactor, maintaining the inside of the reactor in a reduced pressure, pressurizing the inside of the reactor by introducing chlorine gas for bringing the inside of the reactor into a pressurized state, and cooling the inside of the reactor.

摘要： A camera focal plane shutter according to the invention comprises a shutter blade for opening and closing an exposure aperture to carry out an exposure operation; an electromagnetic actuator for directly driving the shutter blade, and a positioning means for positioning the shutter blade at an operation starting position. This positioning means is comprised of a swing arm supported in a manner enabling it to swing so as to comes into contact with and separate from a drive pin of a rotor, a torsion spring for applying a pushing force so as to push one end of the swing arm against the drive pin, and an eccentric pin which stops the swing arm at a position with a predetermined angle against the pushing force of the torsion spring. Therefore, an impulse force caused by the movement of the shutter blade is eased, and the shutter blade is easily positioned with high accuracy at the operation starting position.

摘要： A focal plane shutter for use in a photographic camera in which a shutter base plate is made of a synthetic resin material and a metallic supporting plate is mounted on a front surface of the shutter base plate. Shafts pivoting levers for driving a leading blade group and trailing blade group are fixed to a front surface of the metallic supporting plate, whereas shafts pivoting arms for driving the leading blade group and the trailing blade group are fixed to a rear surface of the supporting plate. The shafts pivoting the driving arms and supporting arms protrude from a rear surface of the shutter base plate.

摘要： A focal plane shutter includes a first blade group which is moved forward from an unfolding state to an overlapping state to start an exposure in response to the release of a first blade driving spring and a second blade group which is moved forward from an overlapping state to an unfolding state to terminate the exposure in response to the release of a second blade driving spring. The force of the driving springs for applying the impellent force to the blade groups is removed from the corresponding blade groups before each of the blade groups reaches an end of forward movement so that the blade groups are moved by the force of inertia. The driving spring for applying the impellent force to the blade groups is engaged with a first arm formed on one end of a swingably supported brake lever before the blade group reaches the end of forward movement so that a second arm formed on the other endd of the brake lever is rotated to prevent the movement of the blade group. Since the blade groups are moved to the end of forward movement while receiving the braking force by engagement with the second arms of the corresponding brake levers, shock or oscillation at the termination of forward movement is reduced.
摘要翻译：焦平面快门包括第一叶片组，其从展开状态向前移动到重叠状态，以响应于从重叠状态向前移动的第一叶片驱动弹簧和第二叶片组的释放而开始曝光响应于第二刀片驱动弹簧的释放而终止曝光的展开状态。在每个叶片组达到向前运动的结束之前，用于将叶片组施加推动力的驱动弹簧的力从相应的叶片组中移除，使得叶片组通过惯性力而移动。用于将推动力施加到叶片组的驱动弹簧与形成在可摆动支撑的制动杆的一端上的第一臂接合，在叶片组达到向前运动的结束之前，形成在第二臂的另一端上的第二臂制动杆旋转以防止叶片组的移动。由于叶片组通过与相应的制动杆的第二臂接合而接收制动力而移动到向前运动的结束，所以在向前运动终止时的冲击或振动减小。
