Abstract: 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.

Abstract: A self-timer operation informing device, particularly one having an auditory and a visual display device is disclosed. In the case of such information device, since both display devices are always driven in order to carry out the display operation, a problem exists in that the power consumption for the self-timer operation display is large. On the other hand, since it is difficult to confirm the display state by the visual display when the brightness is high, in such cases the auditory display is significant. In other words, the visual display does not have significance under high brightness conditions. A self-timer operation informing device, therefore, selects the driving of the visual or the auditory display device in accordance with the brightness information so as to prevent unnecessary display in order to save the power consumption.

Abstract: A digital display system connected to an exposure indicator in a camera to provide a digital display representative of the exposure value in shutter speed by an array of numerical indicators of the block number eight type. When the numerical value of shutter speed is equal to or larger than one second, the indicator which is directly to the right of the least significant digit is utilized to display an indicium representing a "second" unit as is usual in digital stop watch art by driving a pair of upper-positioned parallel segments in the "FIG. eight" pattern to be lit serially from the least significant digit.

Abstract: 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.

Abstract: An optical disc and an apparatus using it. Prepits are preformed on a surface of the disc at a pitch to facilitate tracking thereof. The prepits are used for both tracking and clock generation. A processed tracking signal and a processed clocking signal are generated from signals generated solely from the preformed prepits.

Abstract: Tracks on a recording medium are divided into blocks each consisting of a block header area and a data area, and a block-synchronous code is added to the block header area while a frame-synchronous code is added to each frame at the data area.

Abstract: Travelling oscillation waves are generated in a lens assembly at an oscillation element by impressing a voltage to an electro-restriction element or elements, whereupon a lens driving operation is performed by frictionally driving a moving element which is pressed in contact with the oscillation element. In the case of manual operation, an oscillation ring operating as the oscillation element is separated from a rotation ring which constitutes the moving element by a clutch device and then the rotation ring is manually rotated for effecting the lens driving operation.

Abstract: A surface wave motor for driving a rotor by a traveling surface wave has at least three pins radially extending from a ring-shaped vibration member to support the vibration member.

Abstract: 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.

Abstract: In a drive system for a vibration wave motor for generating a travelling vibration wave by friction-contacting a vibration member to a movable member and by electro-mechanical energy conversion means contained in one of the vibration member and the movable member to friction-drive the movable member, a standing vibration wave is generated by the electro-mechanical energy conversion means prior to the start.

Abstract: 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.
