摘要： The present invention relates to a battery check device particularly for displaying the state of the power source voltage with color. Until now, the battery checker for displaying the state of the power source voltage with color is provided with a plural number of color light emitting elements so as to display the state of the power source voltage with color by selectively driving the determined display element in accordance with the state of the power source voltage. However, by means of this conventional method, the state of the power source voltage can not be displayed continuously, which is inconvenient. In order to eliminate the above shortcoming, the present invention provides a battery checker for continuously displaying the change of the level of the power source voltage with color by continuously changing the color of the display means in accordance with the signal level corresponding to the state of the power source voltage.

摘要： An apparatus for providing a digital display representative of photographic information which is visible in the viewfinder of a camera. Since the photographic information is comprised of a number of factors, a number of symbols or signs are displayed in association with the digital display so that the photographer can identify multidigit numbers displayed. The structure of the digital display is simplified by using an arrangement of connections between display and display driver which allows for further reduction in size of the camera.

摘要： The present invention relates to an exposure control system for a camera with both priority modes in which the photographic information of either the shutter time or the aperture value and the photographic information including the measured value of the brightness of the object to be photographed are processed so as to obtain a proper exposure value. The system is characterized in that either an optional shutter time or an optional aperture value is set by a common set means, for example, a dial in such a manner that the output of the set means is put in the operation means so as to control the exposure amount. Further, the condition showing whether the value set by the common set means is the aperture value or the shutter value is clearly indicated.

摘要： At the side of the camera body, switches for treating the totally opened F value information of the photographic lens as coded digital information of a certain determined number of bits are connected to the digital exposure operation circuit. At the side of each of the photographic lens which is made interchangeable for the camera body, a signal pin is arranged for indicating the totally opened F value proper to the photographic lens as coded digital information of the above mentioned determined number of bits in such a manner that at the time of mounting the photographic lens on the camera body, the switches at the side of the camera body are closed in selected combination in accordance with the totally opened F value of the lens. Accordingly the totally opened F value of the photographic lens is put into the digital exposure operation circuit.

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) switches a heater from OFF to ON in the specified timing after a seek mode is switched to a following mode. Specifically, for example, on the 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, and this state is kept unchanged until access to the target sector is made.
