Abstract: PROBLEM TO BE SOLVED: To easily control the temperature in the case of heating and also to shorten the latent image forming time by heating a latent image recording part to a temperature equal to or higher than Curie temperature and impressing an electric field so as to form a latent image on a latent image recording medium including a ferroelectric material. SOLUTION: An electrophotographic printer is constituted of a recording means 1, an initializing means 2, a latent image forming means 3, and a charging means 4, etc. The means 2 is controlled so that a corona charger can impress the electric field capable of nearly perfectly orienting the inside polarization of the ferroelectric latent image recording medium of a recording body 1 in one direction. The means 3 simultaneously copes with printing information in a state that a voltage controlled by a grid voltage is impressed on the latent image recording medium of the recording body 1, is irradiated with a semiconductor laser beam 302 modulated by on/off state, and is partially heated to a temp. equal to or higher than the Curie temperature, so that polarization at the part is inversed, and a polarization inversed latent image is formed. Consequently, switching time for polarization inversion can be extremely shortened.

Abstract: PURPOSE: To provide a recording method and a recorder useful in the case of repetitively obtaining many high-quality printing matters by forming a latent image once even though the latent image is not formed at every time of repeating development, transfer and fixation in an electrophotographic process using a recording body having a ferroelectric latent image recording medium. CONSTITUTION: The recording method and the recorder include a latent image forming stage to form the latent image based on printing information on the ferroelectric latent image recording medium 1, an electrifying stage to uniformly electrify the medium 1, a developing stage to develop the latent image so as to obtain a visible image, and a transferring stage to transfer the visible image on the medium 1. In the image forming stage, the medium 1 is quickly cooled after it is heated so that the absolute value of surface potential at the latent image forming part of the medium 1 may be lower than that of the other part.

Abstract: PURPOSE: To repeatedly obtain a large number of high image quality prints by a single time of latent image formation even if a latent image is not formed every time the development and transfer are repeated by electrifying a ferroelectric latent image recording medium before the development. CONSTITUTION: This recording device is constituted to include a latent image forming means 2 for forming the latent image based on printing information on the ferroelectric latent image recording medium, a developing means 4 developing the latent image, to obtain a visible image and a transfer means 5 transferring the visible image onto a recording medium and provide an electrifying means 3 before the developing means 4. Preferably, a charge is uniformly imparted to the latent image recording medium by the electrifying means 3 and preferably, a destaticization means 8 is provided after the transfer means 5 and just before the electrifying means 3. Further, it is preferable that the charge having a polarity opposite to that of the electrifying means 3 is uniformly imparted to the latent image recording medium by the destaticization means 8. In this way, when the charge is uniformly applied to the full surface of the ferroelectric latent image recording medium on which the latent image is formed, the development so as to amplify the surface potential difference between an image part and a background part is attained.

Abstract: PURPOSE:To facilitate the operation of loading and unloading an elastic tube by releasing a position regulating means and separating the first casing automatically from the second casing with the action of am energization means to make a gap wider between a roller and an circular arc inner circumferential surface. CONSTITUTION:A rotor part 34 is turned in such a manner that an elastic tube arranged on a casing body 1 having a circular-arc inner circumferential surface 2 is pressed onto the circular-arc inner circumferential surface with rollers 36a and 36b to feed a liquid in the elastic tube. The casing body 1 is divided into a mobile casing 11 and a fixed casing 12 and the mobile casing 11 is held slidable on the fixed casing 12 while tension springs 9a and 9b are arranged to energize the mobile casing 11 away from the fixed casing 12. A solenoid coil 15 is provided to regulate the mobile casing 11 to a position being coupled to the fixed casing 12. The positional regulation with the solenoid coil 15 is released to allow the mobile casing 11 to be separated from the fixed casing 12 automatically.

Abstract: PURPOSE:To easily mount and disengage an elastic tube by forming a notched part of a specified length along a circumferential direction in the outer peripheral part of a rotor and the rotation/stop of this rotor by detecting the arrival of this notched part at a prescribed Position. CONSTITUTION:The rotor 34 is slowly rotated clockwise by driving of a motor at the time of mounting the elastic tube 3. This rotor 34 is stopped when the magnet 48 of the rotor 34 faces a magnetism detecting sensor 47 and this magnetism detecting sensor 47 emits an output signal. Since the notched part 49 of the rotor 34 comes to the position where the notched part faces the suction side groove 51a of a casing 1 and, therefore, tube retaining arms 52a, 2b are pulled toward the operator and are erected; thereafter, the suction side end 3a of the elastic tube is mounted to the suction side groove 51a and the discharge side end 3b is drawn out of the notched part 49. After the retaining arm 53a is returned to its home position, the rotor 34 is rotated clockwise and the elastic tube 3 is moved and guided along an inner peripheral surface 2a of the casing, by which the elastic tube is mounted into the elastic tube mounting space.

Abstract: PURPOSE:To analyze the silicic acid ions in water with high sensitivity by separating the silicic acid ions from other ions by using a sepn. column, then determining the ions. CONSTITUTION:The color forming reagent supplied from a color developing reagent supplying line 13 into a color developing reagent tank 29 is preheated to a reaction temp. by a color development reactor 16 while the color developing agent is deaerated by a deaerator 18 and is applied with the pressure loss by a pressurizing coil 17. The reagent is then introduced by a pump 12 to a mixing point 11. The reagent is mixed with an electrolytic eluant from the sepn. column 8 at a mixing point 11 and the mixture is introduced to a vessel 16. The mixture is further cooled near to the temp. of an absorption photometer 15 by a cooling coil 22 and is then introduced to the photometer 15. The analysis of a so-called blank state is executed by the photometer 15 with the liquid mixture in which the silicic acid ions are not included. The liquid mixture is discharged to the outside of the system via a drain line 26 while a back pressure is applied thereon by a back pressure coil 23 after the analysis.

Abstract: PURPOSE:To manufacture an optical fixed attenuator capable of easily obtaining a target optical attenuation quantity with high precision and reducing the production of defectives as much as possible at low cost. CONSTITUTION:The end surface of one ferrule 3 between a couple of ferrules 3 and 5 is formed into a slanting plane having a 1st tilt angle theta1 to a plane F crossing the optical axis P of an optical fiber 2, and the end surface of the other ferrule 5 is formed into a slanting plane having a 2nd tilt angle theta2 a little larger than the 1st tilt angle. Then the slanting plane of the ferrule 5 is coated with an optical attenuation film 19 to specific thickness, and the slanting planes 3a and 5a of the couple of ferrules are arranged opposite each other while having the optical axes P of optical fibers 2 aligned with each other, thereby constituting the optical fixed attenuator 1. Then the ferrule 3 is rotated in its circumferential direction by a specific angle on the ferrule 5 to adjust the attenuation value to a target value.
