Title: Magnetic ink recorder
Inventor: MARUNO SUSUMU
IPC: B41J2/06
Filed: 1983-05-18
Abstract: PURPOSE:To enable to stably obtain high-quality images high in recorded density, by a method wherein a heat-fusible magnetic ink is melted by heating by a heating means, and a sufficient quantity of the ink is supplied to a wire by a magnetic force of a supplying magnet. CONSTITUTION:When a voltage V is impressed on a heater 8 proximate to the supplying magnet 3c, the heat-fusible magnetic ink 4 contained in a tank 2 is melted by the heat generated by the heater 8, and the ink thus melted is automatically supplied to faced parts B of a core 3B by magnetic forces to form an ink film 10 in a sufficient amount. Then, a driving means 5 drives an arbitrary one of wires 1 in accordance with a recording signal, whereby the wire 1 is reciprocated through the ink film 10 with a sufficient amount of the ink adhered to the tip thereof, resulting in predetermined recording on a recording paper 7. Accordingly, high-quality images high in recorded density and free from blur can be stably obtained. In addition, when heating is stopped after completing a recording operation, the ink is again solidified, so that it does not make dirt the hands of the user or the recorder.

Title: Method for preventing generation of hydrogen in coated optical fiber
Inventor: NISHIMOTO MASAYUKI
IPC: C03C25/10
Filed: 1986-04-18
Abstract: PURPOSE:To effectively prevent the generation of hydrogen from a resin hardened by ultraviolet rays, by humidifying the resin hardened by ultraviolet rays of an optical fiber core or an optical fiber unit. CONSTITUTION:Resins hardened by ultraviolet rays of an optical fiber core 20 or an optical fiber unit 26 are humidified. The optical fiber core 20 or the optical fiber unit 26 is exposed in an atmosphere of >=80% relative humidity or is immersed in water to humidify them, and in this case, the humidifying effect is enhanced according as the temperature of the atmosphere or water in this humidifying treatment is higher, and especially, the effect is considerably enhanced if this temperature is >=40 deg.C. Water remaining after the humidifying treatment is removed by drying after the treatment because constituting materials of the coated optical fiber are degraded for a long time. Thus, the generation of hydrogen from the resin hardened by ultraviolet rays is effectively prevented.

Title: Multicolor image forming device
Inventor: SHOJI HISAFUMI
IPC: B41J2/525
Filed: 1987-04-09
Abstract: PURPOSE:To enable a correspondence with parallel and serial input methods by generating a control signal so as to modify the sequence for transferring image data in accordance with the input system thereof. CONSTITUTION:As the image data input systems, there are an external device 1 inputting parallel data, and an external device 2 inputting serial data. For the former, an image reader and the like are used, while for the latter an image storage device and a communication equipment are used. Image data is inputted from these devices into an image data input part. Information indicating whether the inputted image data is parallel or serial (surface-sequential) is inputted to a control part, and the sequence for an entire multicolor image forming device is determined. The inputted image data is image processed in an image processing part, and transferred into a latent image forming means. It has a delay means which controls the timing of forming a latent image according to the sequence and forms a latent image on an image carrier in an electrophotographic part. Thus the operation can be corresponded with the parallel and serial (surface-sequential) input methods of image data, and a multicolor image can be formed quickly.
