摘要： A liquid crystal display device for a camera includes a display member having liquid crystal material for providing a display of photographic information, and a focusing glass for forming an image of an object which is to be photographed. A mask is arranged to face the display member and the focusing glass, the mask including a first transparent part which faces a display part of the display member, and a second transparent part which faces the object image formed on the focusing glass. A light shading part is provided between the first and second transparent parts of the mask to shade an end part of the display member from light. The mask enables view finder optics provided in the camera to display a rectangular view field having straight sides to the camera user. This is accomplished by forming boundary lines between the first and second transparent parts and the light shading part of the mask, wherein each boundary line substantially forms an arc having a center located on a straight line which is perpendicular to one of a long and short side of the view field, and which line passes through the center of the view field. The arcuate boundary lines overcome distortion produced by the view finder optics so that they are visually recognized as being straight.

摘要： An automatic exposure control device for a camera capable of permitting flash photography includes an exposure computing portion for natural light photography wherein the computing portion generates an exposure signal corresponding to the brightness of an object and an exposure computing portion for flash photography wherein the computing portion is arranged to generate an exposure signal suitable for a flash photographing operation. An exposure control portion is responsive to one of the exposure signals generated by the natural light photographing exposure computing portion and the flash photographing exposure computing portion. A change-over device applies one of the exposure signals to the exposure control portion. An electromagnetic release device actuates the internal mechanism of the camera wherein the release device produces an electrical signal when it operates. A signal generating device generates a selection signal until the electrical signal is applied from the electromagnetic release device and generates an inhibition signal after application of the electrical signal. A discharge tube emits a flash therefrom an an accumulating portion accumulates light emitting energy for the discharge tube. A detecting device detects the accumulation of the light emitting energy and is arranged to produce a detection signal when the accumulated amount of energy reaches a predetermined value. A triggering device enables the discharge tube to emit a flash in response to the detection signal. The automatic exposure control device performs other functions relative to exposure control.

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.
