Abstract: Light is irradiated onto a photographic film which is conveyed by a film carrier. A compressor generates cooling air for cooling the photographic film. A guide pipe guides the cooling air generated by the compressor to at least one of a region of the photographic film, onto which the light is irradiated, and a reverse surface of the region. In this way, since the cooling air generated by the compressor is guided to the photographic film, the photographic film can be cooled by the cooling air having large amount of flow, velocity of flow, or the like.

Abstract: After scan conditions are determined by the pre-scan, a temperature of a focus lens unit is measured. When the difference between the measured temperature and a set temperature data stored in a RAM is less than 4° C., a focus position is calculated based on set focus position data in the RAM and temperature correction data which is decided according to the temperature difference. When the temperature difference is 4° C. or more, a focus search operation is carried out to detect the focus position. Focus position data and temperature data, obtained by the focus search operation, are written in the RAM as set focus position data and set temperature data. It is possible to omit the focus search operation if temperature fluctuation is small.

Abstract: A system for monitoring the amount of light emitted from a surface emitting laser includes a beam splitter which is fixed to the surface emitting laser and splits a part of a laser beam emitted from the laser as a monitor light, and a photodetector which detects the monitor light.

Abstract: The transaction processing throughput of a system in which a plurality of servers cooperatively perform distributed processing of transactions is improved. The servers (1a, 1b, 1c, . . .) are connected to each other through a communication network (2), and a resources (16) and a log 18 are distributed over these servers. When one of the servers, e.g., the server (1a) receives a transaction, the server (1a) instructs the servers (1b, 1c, . . . ) over which the resource 16 relating to this transaction are distributed to update their resources, acquires the log data representing the updating contents and stores the log data in its log (18)The servers (1b, 1c, . . .) update the resources in accordance with the instruction. Even when a fault occurs in one of the servers (1b, 1c, . . .) during the transaction processing so that the updating of the resources has not been executed, the system assumes that all the resource has been updated and proceeds to processing the following transaction.

Abstract: The present invention is directed toward a wide-angle lens. Because of a small quantity (two) of lens elements, the wide-angle lens facilitates size and weight reduction and permits low-cost manufacture. The lens is made from plastic, which permits further cost reduction. The lens is particularly useful when employed in CCD cameras.

Abstract: In an image scanning system, a deflector is contained in a casing having a cover glass which transmits a scanning light beam deflected by the deflector. An air flow is formed in front of the cover glass to prevent dust adhesion.

Abstract: The improved image reading and reproducing apparatus comprising a scanner which reads an image on an original photoelectrically, an image processor which performs specified image processing on image data output from the scanner and a printer which writes the image data output from the image processor into a memory, reads the recording image data sequentially from the memory and records an image on an auxiliary scanned recording material in accordance with the recording image data, satisfies the following relation (1):Tr.gtoreq.(82.5/Vp)+.alpha. (1)where Tr is the time of reading one frame of the original image from the start of image reading with the scanner to the storage of obtained recording image data in the memory in the printer; Vp is the speed of auxiliary scanning of the recording material in the printer; and .alpha. is the overhead time which occurs unavoidably between the recordings of two successive frames of the image in the printer.

Abstract: In a light beam scanning recording device, a color image is recorded on a recording material by scanning the recording material in a main scanning direction and a sub-scanning direction with light beams of three different wavelengths modulated according to an image signal. A light source which emits a plurality of light beams which form a predetermined number of beam spots on the recording material arranged in the sub-scanning direction is used as the light source for emitting light beams of each wavelength, whereby recording is effected simultaneously along the predetermined number of main scanning lines.

Abstract: The present invention provides a wide-angle lens for film-combined type cameras, comprising a first lens element having a negative refractive power and a second lens element having a positive refractive power which have more than one aspherical surface.

Abstract: A pen-type bar code reader uses a reflector formed on a concave lens surface of a convex lens system with respect to a bar code detector, except a region for transmitting a light flux. The convex lens system is mounted so that its optical axis is angled with respect to the light flux from the detector, and a bar code illuminating light source is provided in a position between the detector and the convex lens system and opposite to the light flux from the detector with respect to the optical axis of the convex lens system.
