摘要： A digital system for controlling coordination of the various portions of the camera to operate in selected modes including the automatic and bulb modes is provided with signal forming means comprising a count start switch and a bulb control switch connected in parallel to each other. Where the automatic mode is selected, in a predetermined time interval after the initiation of an actuation of release of the camera, as the both switches are open, the signal forming means produces an actuating signal which is then applied to discriminating means, causing the shutter to operate automatically. Where the bulb mode is selected, no actuating signal is produced even after the termination of duration of the predetermined time interval so that the discriminating means permits the opening of the shutter to continue until the termination of the release actuation.

摘要： A safety device for preventing non exposure of film in a camera having a count switch which is normally closed prior to shutter release operation, the switch being opened after the shutter release operation begins to enable a timing circuit to start operating. In a preferred embodiment, the device includes a NOR gate having an input connected to one side of the count switch, and its output connected to the set terminal of a flip-flop which enables the shutter release operation. Another input of the NOR gate is connected to a differentiation circuit which provides an output signal when the shutter release button on the camera is actuated. This circuit arrangement operates so that the flip-flop is not set if the count switch is accidently in an open state when the release button is actuated. The shutter release operation is thereby prevented until the count switch is restored to working order.

摘要： Embodiments of the present invention help to accomplish accurate and reliable clearance control. In one embodiment of the present invention, a disk drive device adjusts the clearance between a head element portion and a disk with a heater on a slider. The clearance control according to the present embodiment incorporates the variation in heater power efficiency in the clearance variation depending on the radial position. The clearance variation in a unit of heater power varies depending on the radial position. Taking account of the variation in the heater power efficiency in the thermal fly-height control (TFC) depending on the radial position in addition to the clearance variation between the head element portion and the disk caused by variation in fly-height or attitude, accomplishes more accurate TFC.

摘要： Embodiments of the invention reduce a possibility that a head will collide with a medium when the clearance between the head and the medium is adjusted by using a medium, and sufficiently reduce the clearance even at an initial stage of accessing a data area. In one embodiment, a hard disk drive (HDD) keeps a heater in an OFF state for a period of time from the start of seek operation until the specified timing after a following mode starts. This prevents a head element from colliding with a magnetic disk, and also prevents flying properties from changing due to the deformation of the ABS. In the above specified timing, the heater is switched from OFF to ON. Specifically, for example, on completion of seek operation, in the timing in which a head arrives at a target track, or in the timing in which an HDC/MPU enters the following mode, the heater is turned ON.

摘要： In a system for setting the aperture in a camera for flash photography, a minimum aperture is computed in response to parameters such as distance to an object, stroboscopic guide number and film sensitivity. In one embodiment, a predetermined aperture value is preestablished in the system and the computed minimum aperture is compared therewith. Where the computed minimum aperture is below such predetermined aperture value, such computed minimum aperture is used in flash photography. On the other hand, when the computed minimum aperture is above such predetermined aperture value, an aperture larger than the predetermined minimum aperture value is used in flash photography. Other embodiments for flash aperture setting are also set forth.
