摘要： A camera and interchangeable lenses for such camera in which it is automatically detected whether or not the lens mounted on the camera has an automatic focusing capability. If it does, respective sets of electrical contacts provided on the lens and camera body are employed to transmit and receive a series of different data between the camera body and the lens. If it does not, the only a single datum is transmitted, for example, an open lens-stop value of the lens, is transmitted over the two sets of contacts. An automatic focusing actuation voltage applied from the camera body can be sensed to determine whether or not the lens has the automatic focusing capability.
摘要翻译：用于这种相机的照相机和可更换镜头，其中自动检测安装在相机上的镜头是否具有自动聚焦能力。如果是这样，则使用设置在透镜和照相机主体上的各组电触点在相机主体和透镜之间传送和接收一系列不同的数据。如果不是，仅传送单个数据，例如，透镜的透镜停止值的打开，通过两组触点传送。可以感测从相机机身施加的自动对焦致动电压，以确定透镜是否具有自动聚焦能力。

摘要： 2'-Deoxy-3',5'-di-O-alkylcarbonyl-5-fluorouridine derivatives possessing strong anti-tumor activity with weak toxicity and represented by the general formula: ##STR1## wherein R stands for an alkyl group, an alkoxy group or a halogen atom, m for zero or an integer of 1-3, and n for an integer of 1-14, with the proviso that when m is 2 or 3, R's may be the same or different and that when m is 2 and the adjacent two R's are alkoxy groups, the two alkyl moieties of the alkoxy groups may be combined to form together with the two adjacent oxa bridging members an alkylenedioxy group as a whole. These derivatives are prepared by acylating a 2'-deoxy-3',5'-di-O-alkylcarbonyl-5-fluorouridine with corresponding benzoyl halides and are useful as active ingredients for anti-tumor agents, especially for oral administration.

This ensures that the shutter will be closed even when the light emitted by the flash is insufficient to achieve the proper level of exposure.

摘要： An automatic exposure camera of the stop value control type is provided with lens stop braking to improve the accuracy of the lens stopping operation while at the same time maintaining a high operating speed. A brake magnet mechanism is provided for decelerating the lens stopping mechanism in response to a control circuit. In one form, the control circuit operates the brake magnet mechanism to effect deceleration slightly before the quantity of light reaches a suitable exposure value. Thereafter, when a stop value providing a suitable exposure value is obtained, stopping the lens stopping operation can be done with very high accuracy. In another form, the control circuit compares the variation in light due to the change in aperture with a variation rate to control the energization and de-energization of the brake magnet. In this way, the non-linear operation which is particularly evident at minimal aperture values is eliminated.

摘要： An SLR camera includes a light measuring and computing circuit 1-7 whose output is fed to a comparator 8 together with the analog output of a D/A converter 12 coupled to a bidirectional counter 13. The counter is servo-loop driven to achieve circuit balance through AND gates 10, 11 in response to the comparator outputs, and the decoded counter outputs energize an appropriate LED display element L1-L16. The AND gates are disabled by the closing of switch 17 in response to the raising of the reflex mirror, to thereby lock the counter and display and prevent fluctuations therein. A capacitive time delay may be provided after the reopening of the switch following the lowering of the mirror to allow circuit transients to settle out.

摘要： An electrical system to be used in a camera for controlling exposure time. The electrical system includes a pair of substantially identical constant voltage sources respectively having inputs connected together. A buffer circuit is coupled between an interconnection of these inputs and the collector of a compression transistor to which a photosensitive means is connected and whose base is coupled to one of the constant voltage sources. A timing circuit is coupled to an expansion transistor, whose base is coupled to the other of the constant voltage sources.

摘要： New methods for phase contrast imaging in transmission electron microscopy use the imaging electron beam itself to prepare a hole-free thin film for use as an effective phase plate, in some cases eliminating the need for ex-situ fabrication of a hole and reducing requirements for the precision of the ZPP hardware. The electron optical properties of the ZPP hardware are modified primarily in two ways: by boring a hole using the electron beam; and/or by modifying the electro-optical properties by charging induced by the primary beam. Furthermore a method where the sample is focused by a lens downstream from the ZPP hardware is disclosed. A method for transferring a back focal plane of the objective lens to a selected area aperture plane and any plane conjugated with the back focal plane of the objective lens is also provided.
