Abstract: In a developer depositing unit for an image forming apparatus, a developer is supplied to a developer carrying roller by a supply roller. The developer is charged by the frictional charge produced by contact between the supply roller and the developer carrying roller. The charged developer is displaced from the developer carrying roller to an ordinary sheet of paper, as the sheet of paper is passed around an electrode roller, to be thus electrostatically deposited on a sheet. A ground conductive brush is positioned to contact both the supply roller and the developer carrying roller to remove any excessive built-up charge on the supply roller and the developer carrying roller. The brush also prevents a build-up of developer on both rollers that could result in their becoming clogged.

Abstract: A method for determining exposure amount by making use of the fact that values in which the photometric data on a lowest-density portion of a color film is subtracted from tricolor photometric data are approximately the same irrespective of the type of film. The lowest-density data is subtracted from the tricolor photometric data to determine tricolor corrected data. This tricolor corrected data is normalized, and the tricolor normalized data is compared with a reference value so as to be classified into tricolor normalized data. The tricolor photometric data is selected in correspondence with this classification, and the exposure amount is determined on the basis of an average value of the tricolor photometric data selected. As a result, it is possible to print various types of film under the conditions of print exposure of a reference film type without requiring information indicating the film type.

Abstract: A dampening bar assembly comprised of a pair of support blocks held in parallel spaced-apart relationship by a pair of transverse frame members attached between the support blocks at each end of the support blocks forming a rigid rectangular frame. A number of dampening bars including string vibration dampening pads mounted to the bottom side of each dampening bar are slideably mounted parallel to each other transversely between the support blocks in vertical slots formed in the opposing support block sides. Compression springs mounted in cavities formed in the bottom of each slot provide an upwardly urging force on each end of the dampening bars. Each support block includes a lengthwise aperture therethrough for receiving a square hardwood rod to retain the compression springs in a compressed configuration to provide for assembly and disassembly of the dampening bar assembly. The dampening bar assembly is designed to be used with a stringed instrument such as an auto harp.

Abstract: An image recording apparatus for recording an output color image on an image recording medium, provides a cyanogen filter (or a red filter), a magenta filter (or a green filter) and a yellow filter (or a blue filter), each of them relating to a complementary (or same) color of the basic three primary colors (that is red, green and blue). Each filter is insertable into an optical path. The apparatus also provides a plurality of color designation switch buttons designating several kinds of hue colors (excepting the basic primary colors) on an operation panel of the apparatus body. The amount of the insertion of each kind of the filters into the optical path is adjustable by computer control according to the color designation switch buttons.

Abstract: French horns with four finger valves and one change horn valve, instead of the standard three finger valves and one change horn valve enable play in twelve keys, as well as twelve tones. Point and dimple connections between key levers and rotary valve string bars provide smooth translation of the string bars and smooth rotation of the rotary valve hubs. Screw-on mouthpieces and mouthpipes have smooth identical inner diameters to avoid the airstream disrupting steps of conventional push-in mouthpieces. Cork block mountings between the tubes, valves and slides instead of the standard soldered metal mountings avoid transmission of vibrations between the tubes. Hand straps steady the French horns instead of the usual finger hooks.

Abstract: Paper handling mechanisms for printers, copiers and the like typically have a separate paper feeding mechanism associated with each paper tray. The separate paper feeding mechanisms can only remove paper from the associated tray. Therefore, the paper handling mechanisms are redundant, space consuming, and inefficient to use. Disclosed herein is a paper handling mechanism that uses a single paper-feeding mechanism to remove paper from a plurality of trays. Since a separate paper-feeding mechanism is not required for each tray, more trays may be disposed in the same vertical space of prior printers or copiers. Advantageously, the single paper-feeding mechanism moves generally vertically, and the trays selectively move generally horizontally to intersect the paper-feeding mechanism. Preferably, a plurality of gears are disposed adjacent each horizontally moveable tray. The plurality of gears are adapted to engage a corresponding gear member on each of the respective trays.

Abstract: An image recording apparatus has an exposing device in which the light from a light source is irradiated to an original text and a photosensitive, pressure-sensitive paper is exposed to the light from the text in correspondence to the image of the text. The image recording apparatus is designed so that the light source and the photosensitive, pressure-sensitive paper have a relative movement by means of a movement device, with the moving speed being varied by means of a moving speed control device. The duration of exposure of the photosensitive, pressure-sensitive paper by the exposing device is varied in response to the moving speed, whereby the level of exposure can be varied. Accordingly, this image recording apparatus, which is simple in structure, accomplishes a variable exposure level for the photosensitive, pressure-sensitive paper without the need of varying the light output of the light source and regardless of the type of the light source.

Abstract: An apparatus and method for packaging citrus fruit or discrete articles in a tightly packed pattern or arrangement closely resembling that of a hand packed box. A two-part telescoped box is conveyed in inverted position to a box filling and counting station, the box including an box inner part in which the side and end flaps are in open relation at the box filling station. At the counting station, fruit is being oscillated transversely of their path of travel so as to singulate the fruit into a plurality of counting stations arranged in a row and in a valley. When the row count has been satisfied, all of the fruit in the row are lifted upwardly for discharge into the open box. When the full count is satisfied, the filled box with fruit extending above the top of the outer box is moved to a box handling station in which the inner box is lifted to a height where the side and end flaps of the inner box may be folded over the top fruit.

Abstract: A device is provided for remotely controlling an electrically activated unit, such as a camera or appliance receptacle, by utilizing a conventional infrared transmitter. The device includes an infrared detector for detecting an infrared signal pulse from the conventional transmitter and which produces an electrical output pulse signal for each detected infrared pulse. A counter counts the output signal pulses from the infrared detector while a timer periodically resets the counter to zero. Whenever the count in the counter exceeds a predetermined number before being reset by the timer, an output signal is generated which activates the remote unit. The counter and the timer thus prevent unintended activation of the remote unit by ambient infrared radiation.

Abstract: In an autofocus apparatus for an imaging means such as a TV camera, an object image signal is produced by an imaging means and a focusing operation is conducted automatically by moving a focusing lens so as to maximize a high frequency component of the image signal. Automatic focusing operation is commenced only when the level of the image signal has remained smaller than the threshold value for longer than a prescribed period of time, whereby no unnecessary automatic focusing operation is conducted when the level of the high frequency component decreases because of movement of the camera or the object it is imaging.
