Title: Developing device
Inventor: UCHIDA TOSHIO
IPC: G03G15/08
Filed: 1992-07-27
Abstract: PURPOSE:To prevent the soiling of an electrode roll caused by the sticking of toner, to form a uniform toner layer and to obtain a stable image by providing a cleaning member on the electrode roll provided opposite to a developer carrier. CONSTITUTION:The electrode roll 5 is arranged so as to be opposite to a position where two N-poles of the magnet roll 4 of the developer carrier 13 are adjacent each other. The toner having a small electrostatic charging amount in a magnetic brush on the developer carrier 13 and that electrostatically charged to the reverse polarity are stuck onto the electrode roll 5. However, the stuck toner is carried by the rotation of the electrode roll 5 and peeled by an electrode roll cleaning member 6, to be recovered into a developer housing part 12. Therefore in the position where the developer carrier 13 is placed opposite to the electrode roll 5, the surface of the electrode roll 5 is maintained in a state where it is not soiled with the toner and the uniform toner layer can be formed on the developer carrier 13.

Title: Line abnormality detection device
Inventor: NAKAMURA TAKEFUMI
IPC: H04B17/00
Filed: 1991-08-05
Abstract: PURPOSE:To detect a line abnormality on a transmitter by providing a comparator on the transmitter and monitoring the level of a transmission signal using this comparator. CONSTITUTION:A comparator 1 is provided on a transmitter 10. The comparator 1 compares the levels between an input signal to an amplifier 3 and an output signal from the amplifier 3. When a communication line 7 is disconnected, signal power to be consumed to a reception load 5 on a receiver 29 through a transmission load 4 is eliminated. The level of the output signal from the amplifier 3 rises to be almost equal to the level of the output signal from a signal source 2. In the case a straight circuit 7 is shortcircuited, the level of the output signal from the amplifier 3 deteriorates. Therefore, a line abnormality can be detected on the transmitter 10 by using the output of the comparator 1 as an abnormality notification signal 6. By providing a U link on the output signal of the transmitter 10, the abnormality in the transmitter 10 and in the straight circuit can be discriminated.

Abstract: PURPOSE:To easily read a vertically written sentence, to lengthen a recording medium and to display a large volume of sentences, etc., by selectively applying a voltage to a recording electrode while the recording medium is moved horizontally, and forming an image pattern on the recording medium. CONSTITUTION:A developer carrying belt 14 moves to carry developer in a developer vessel 10 upward, and the developer is attracted to the upper-most nonmagnetic cylinder 3 by the magnetic force of a rotary magnet 2. By the developer carrying belt 14 and the rotation of the rotary magnet 2, the developer forms a uniform layer around the recording electrode 4, and slightly comes into contact with the recording medium 5.

On the other hand, when a prescribed voltage is applied to the recording medium 5, electromagnetic force arises to fix the developer on the recording medium 5. Thus, a vertically written sentence can be read more readily, the recording medium is lengthened, whereby a large volume of sentences, etc., can be displayed.

Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a laser-beam direct writing device and to reduce the running cost, size, and manufacturing cost of the device, by constituting a laser light outputting section which outputs laser light by using a solid- state laser. SOLUTION: In an SHG laser 3, an optical crystal 42 absorbs infrared rays R2 outputted from an infrared semiconductor laser 41 and, at the same time, outputs infrared rays R3 having a different wavelength to a second harmonic generating element 42. On the other hand, the element 43 outputs the infrared rays R3 and blue laser light R1 which is the second harmonic of the infrared rays R3 to an output mirror 44. When the mirror 44 totally reflects the infrared rays R3, the rays R3 are amplified by means of an optical resonator composed of the end face of the crystal 42 on the laser 41 side and the concave surface of the mirror 44. When the infrared rays R3 are amplified, the level of the blue laser light R1 gradually becomes higher and, when the level exceeds a prescribed threshold, the laser light R1 is radiated from the mirror 44.

Filed: 1989-08-29
Abstract: PURPOSE:To obtain the subject solution having high stability to enable the coating operation in air and form an easily sinterable coating film by using a specific alkoxy alcohol in a process for producing the oxide from metal alkoxide. CONSTITUTION:Metallic Ba or Sr is reacted with and dissolved in a compound expressed by general formula RO(CH2)2OH (R is methyl, ethyl, propyl, butyl or phenyl). The objective solution having the above properties is produced by mixing a Ti and/or Zr alkoxide to the solution and heating the mixture. A solution giving a transparent coating film is difficult to obtain when the molar ratio of Ti and/or Zr to Ba and/or Sr is >=2 and, accordingly, 0.5-2mol of water (based on 1mol of Ti and/or Zr) is added to the mixed solution after heating. A solution for producing a compound oxide thin film stable to water and having high concentration can be produced by using the alkoxy alcohol.
