Abstract: An enveloping device (1), capable of repeatedly performing a process for producing an envelope and inserting a content into the envelope at high speed, comprises: a film feeder (2) for feeding a film (7) wound on a roll and supplied in the form of two overlapping folds that extend in a width direction (W); an envelope making device (3) for repeatedly forming an envelope by cutting and fusing, in a longitudinal direction of the film (7), the two overlapping folds while conveying the film; an envelope conveying conveyor (5) which conveys a plurality of envelopes (8) while arranging these envelopes in a line; and an inserting device (6) for inserting a content (9) into each envelope (8) conveyed by the envelope conveyor (5).

Abstract: An enveloping device (1) capable of successively performing a process for producing an envelope and inserting a content into the envelope at high speed comprises: film feeding means (2) for feeding a film (7) wound in the form of a roll in a shape overlapping in two folds in the middle of a width direction indicated by an arrow W; an envelope making device (3) for successively forming an envelope by fusing the middle of a longitudinal direction of the film (7) overlapping in two folds while conveying the film; envelope conveying means (5) which is a conveyor for conveying a plurality of envelopes (8) while arranging the envelopes in a line; and an inserting device (6) for inserting contents (9) into the envelopes (8) conveyed by the envelope conveying means (5).

Abstract: A light-emitting unit, including LEDs mounted on both sides of a substrate, simulates a spherical light source. The LED on each side of the substrate is enclosed by a lens made of a material containing light-dispersing particles. The substrate is provided with a wiring pattern connected to the LEDs. Each of the light-dispersing lenses has a circular periphery which is adjacent to an edge of the substrate.

Abstract: To assure that the space efficiency of a recording apparatus can be improved, the length of each of cables to be electrically connected to a mechanism section can be optimized, and the recording apparatus having excellent handling properties can be produced with small dimensions at a reduced cost, a controlling section for controlling a mechanism section substantially composed of an automatic feeding section, a conveying section, a discharging section and a recording section, each of which is associated with a recording operation to be performed by the recording apparatus, is arranged above the mechanism section.

Abstract: An ink-jet recording apparatus includes a positioning device for postioning a recording head on a carriage and an electrical connecting device for establishing electrical connection between the recording head and a main body portion. The positioning device and the electrical connecting device are provided on the carriage independently of each other. Therefore, the recording head and an ink tank can be certainly and simply installed on the recording apparatus. Also, an information processing system employs such recording apparatus to output input information, such as characters, image or so forth on a recording medium.

Abstract: A bone inducing material comprising a piezoelectric porous membrane having through-holes of an average pore size of about 0.1 to 5 .mu.m is disclosed. When the bone inducing material according to the present invention is used, bone is rapidly regenerated, and new formation of bone occurs. The bone inducing material is particularly useful in the dental field, for example, for treatment of periodontal diseases by GTR method.

Abstract: An image recording apparatus for performing image recording on a recording medium by using an ink sheet having a plurality of colors of ink includes a recording head acting on the ink sheet to perform image recording on the recording medium, a first feeding unit for feeding the ink sheet through a clutch, a second feeding unit for feeding the ink sheet without going through the clutch, and a unit for selectively switching between the first feeding unit and the second feeding unit.

Abstract: An ink jet recorder is provided with a recovery device for preventing unsatisfactory ink discharge of a recording head, the recovery device being provided with ink suction means having a cap covering an ink discharge port, a vent valve for opening and closing the interior of the cap with respect to the atmosphere and a suction pump for producing a negative pressure in the cap, and wiping means having a cleaning blade adapted to be advanced and retracted relative to the ink discharge port. The cleaning blade is protruded when a motor effecting the sequence operation of the ink suction means revolves in one direction, and is stopped at its retracted position when the motor revolves in the opposite drection.
