Abstract: A process is described for preservation microfilming in which variations in the "fade" or background coloration of materials to be recorded is accommodated for. In particular, the process initially develops a characteristic of the camera based workstation itself which relates an exposure meter output with a select sequence of variations of the light source used with the workstation. A pseudo background target of constant hue such as a beige color is used for this purpose. A sample card also is utilized which carries a sequence of color samples each generally within a pertinent range of the spectra associated with the general coloration of the work to be recorded. Reflectance densitometer readings are taken for each of the samples on this card and the card, itself, is recorded on microfilm. The images of the samples on that test microfilm then are evaluated utilizing a transmittance densitometer.

Abstract: A thermal fixing device mounted in an image recording apparatus, includes a presser-roller automatically moved away from a heat roller when a predetermined period of time or more elapses after completion of the thermal fixing of a recording medium, on or before a subsequent recording medium is fed, thus avoiding the continuity of a state in which a thermal fixing belt for feeding the recording medium is interposed and pressed between the heat roller and the presser-roller over a long period of time. Accordingly, this thermal fixing device enables the prevention of deformation in the thermal fixing belt by heat and pressure and achieves stable use of the thermal fixing belt.

Abstract: The present invention relates to a loudspeaker diaphragm which is provided with a rear load and the vibration characteristic of which is improved in that the work to be performed for compressing the air behind the loudspeaker diaphragm is reduced. For this purpose, the loudspeaker diaphragm is provided with openings so that the air located behind the loudspeaker diaphragm can escape. At the same time, the introduction of the openings causes a decoupling of the vibrating diaphragm parts with respect to the frequency response when the loudspeaker diaphragm and the openings are suitably dimensioned, so that it is predominantly the inner part of the loudspeaker diaphragm which vibrates in the case of high notes, while the entire loudspeaker diaphragm vibrates in the case of low notes.

Abstract: Sheet loading in an image recording apparatus is automatically performed by drawing the leading edge of an elongated, web-like image photosensitive recording medium out of a sheet cartridge, passing it through a predetermined sheet feed path provided between the sheet cartridge and a take-up shaft, and attaching the leader portion of the recording medium to the take-up shaft. A plurality of sensors are disposed alongside the sheet feed path for sensing that the sheet loading is being appropriately performed. The recording medium is successively moved to each of the sensors, and if the recording medium is not sensed thereby, it is rewound around the cartridge shaft.

Abstract: A camera using a film of cartridge type. A strip of film is accommodated in a shell in the form of a roll filmstrip which is wound on a film spool. The film is automatically loaded into the camera when the film cartridge is accommodated in a cartridge chamber of the camera. When the film spool is rotated in the roll filmstrip loosening direction, the filmstrip is fed forward from the shell through the film exit of the film cartridge. When the film spool is rotated in the opposite direction, the film is rewound and drawn back into the shell. The camera is provided with a receiving member between the cartridge chamber and a film exposing opening. The receiving member engages the film exit of the film cartridge accommodated in the cartridge chamber. Consequently, the space in the shell of the film cartridge and the space in the film exposing opening are connected with each other in light-intercepted condition. The film cartridge and the receiving member are pressed against each other.
