摘要： The present invention relates to a liquid crystal cell having a plural number of electrode pairs arranged on both sides of the liquid crystal matter so as to be opposed to each other, being characterized in that a pulse wave generating device for generating the first pulse wave with smaller amplitude than the threshold valve for lighting the liquid crystal and the second pulse wave with larger amplitude than the threshold value for lighting the liquid crystal in reversed phase to each other and a gate device for selectively applying the outputs of the pulse wave generating device to each electrode of the liquid crystal cell in accordance with the input signal are provided. Thus only the voltage between the selecting electrodes is highter than the threshold value. An input change over device is provided so as to change over the input signal group in a time dividing way in such a manner that a plural number of dots can be displayed visually at the same time, as a result, the wiring is simplified.

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： In the automatic exposure control camera disclosed, a memory has data stored therein on the basis of the object brightness and is periodically reset by a reset device to obtain new brightness data, while an exposure control controls exposure on the basis of the data. A signal device ordinarily produces a first signal but locks into a second signal after an external operation. A gate arrangement between the memory and the reset device passes reset signals to the memory, but responds to the second signal to inhibit the reset so as to latch the content of the memory.

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： A mechanism for compensating the servo data in a disk storage drive is provided. On each recording surface of a disk, a plurality of servo regions are diametrally formed in data regions along the diametral direction of the disk. In the servo region, a gray code (cyclic binary code) representing the address of a data track is recorded so as to correspond to the data track, and a burst pattern as a signal for positioning the head on the track are recorded. In the data track region, tracks are formed at a predetermined pitch P and in the tracks, a plurality of data is recorded. ID (Identification) is the identification information of the individual data. A servo compensation signal region is formed at a position sandwiched by the data region and the servo region known as the write recovery area. This is to compensate the servo signal in the servo region, thereby to enable error recovery when a read error or the like occurs in the servo region.
