摘要:
A laminated glass has a laminated resin film and two glass plates laminated on both sides of the laminated resin film. The laminated resin film is composed of at least one polyvinyl butyral film and at least one fluorine resin film which are laminated. A laminated glass is composed of at least two non-tempered glass plates and at least one resin interlayer film which are bonded. At least one of the glass plates is a non-tempered borosilicate glass plate.

An image information filing apparatus includes a data compressing circuit for compressing line image information corresponding to each scanning line to decrease the redundancy of the image information and a circuit section for adding line sync code and EOL and CRC codes to the head and end of the line image information, respectively. When the line sync code is MFM-modulated together with the line image information, one pulse is removed from the modulated pulses corresponding to the line sync code. The line image information are separated from each other by the detection of the line sync code with the missing pulse.

In the disclosed viewfinder, a focusing plate receives light from an objective via a reflex mirror, and after focusing, passes light to an eyepiece via a penta prism. A by-pass optical system receives light from outside the view field of the viewfinder and directs the light through an information carrier outside the optical path of the photographic light and into the penta prism so that the information can be displayed close to the view field of the viewfinder.

A camera includes a viewfinder with an indicator having two opposing substrates sandwiching a liquid crystal between them. One substrate includes a common electrode arrangement with a plurality of electrodes. The other substrate includes a segmented electrode arrangement with a number of electrodes facing the respective electrodes of the common electrode arrrangement. Short-circuit connectors connect predetermined electrodes in the segmented electrode arrangement. A first contactor has a number of conductors connected to the respective electrodes of the segmented electrode arrangement to deliver predetermined drive signals thereto. At least one of the short-circuiting connectors is arranged at the input portion of the first contactor. A second contactor with a number of conductors is connected to respective electrodes of the common electrode arrangement so as to deliver predetermined drive signals thereto.

In the disclosed camera, an exposure value determining arrangement produces an electrical signal in response to a light measuring facility and a film sensitivity setting device. An exposure factor unit determines a combination of shutter speed and aperture value for a proper exposure in response to the exposure value determining arrangement. A control connected to the exposure factor unit varies the combination of exposure factors in the exposure factor unit in response to the set position of a program constant setting arrangement which is set for a particular program constant.

A conversion system for a camera of a type controlled through computation of digital information. The system converts a coded digital value into a digital value of another coding. The code which comprises a gray code representing an integer part of the value and a code pattern representing a decimal part of the value is converted in such a manner that: The integer part is converted into a binary code while the decimal part is converted into a code to which a weight of 1/2, 1/4 or 1/8 is applied. With such a method of conversion employed, values set at 1/3 increment or decrement steps such as ASA film sensitivity values are readily converted into binary codes to facilitate the computing operation of the camera.

An optical disk recording and reproducing apparatus includes an optical disk memory and an optical head for writing and reading out data on and from the optical disk memory by accessing onto a track of this optical disk memory and irradiating a laser beam onto a desired track. The tracks of this optical disk memory are divided into a user inaccessible area, and non-recording area, and user accessible area which are respectively provided inside and outside of the user inaccessible area. A plurality of blocks is allocated to each track in these user inaccessible area and user accessible area. Block head data representative of a block position is recorded in each block. When the optical head inadvertently enters the user inaccessible area an operation is performed to reposition the head at the user accessible area.
摘要:
In the camera disclosed, a display device adapted for displaying photographic information and a pattern, etc., with a liquid crystal within the camera view finder, a polarizing arrangement which creates a contrast between a portion of the display and another is combined with the liquid crystal. This produces a display with a high contrast portion and a low contrast portion.

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.
