Title: Two-way communication system using single stripe optical fiber
Inventor: KINUGASA NORIO
IPC: H04B10/00
Filed: 1989-04-04
Abstract: PURPOSE:To attain the detection of a fault of an optical fiber and to locate a fault point by providing a transmission means superimposing a monitor signal onto a transmission signal and sending the result, a time count means for an elapsed time after the transmission of the monitor signal till its reception and a discrimination means to each terminal station. CONSTITUTION:In the case of 2-way communication by using a single stripe optical fiber 50 between terminal stations A, B, monitor signal insertion circuits 11, 12 inserting and superimposing a monitor signal onto a transmission signal and sending the resulting signal, time comparison/storage circuits 31, 32 and monitor signal detection circuits 21, 22 are provided on the terminal stations A, B. When a fault occurs in the optical fiber 50, the transmission signal sent from, e.g. the station A is reflected in a faulty point and returns to the station A as a reflection signal. When the monitor signal in the reflection signal is detected by the circuit 21, the circuit 21 sends an insertion command thereby allowing the circuit 31 to stop time count and the result is stored as a 2nd elapsed time. Then the time is compared with a 1st elapsed time from the transmission of the transmission signal till its reception at normal state through the optical fiber 50, then the normal wave and the reflected wave are distinguished, then the fault of the fiber 50 is detected and the fault position is located.

IPC: B41J2/415
Filed: 1985-04-22
Abstract: PURPOSE:To prevent the track of an ion flow with which a recording medium is irradiated from being deflected by providing many opening parts on plural arrays perpendicular to the moving direction of the recording medium on specific condition. CONSTITUTION:Many opening parts 2 of an upper electrode 1 and a lower electrode 3 are provided on plural arrays perpendicular to the moving direction of the recording medium. In this case, those arrays are so provided that opening parts 2 in a next array are arranged successively where when the opening parts 2 are all placed in an ion flow passing state, the distribution of an electrostatic image charge which is already formed by opening parts 2 in the last and preceding arrays is divided into a right and a left part symmetrical about a printing line perpendicular to the moving direction of the recording medium. Consequently, the irradiated ion flow receives a Coulomb force of the same level between the right and left and travels straight to record data on the recording medium. Thus, the electrostatic image is formed uniformly and, specially, when a solid black part is recorded, an image having small irregularity in recording density is obtained.

Abstract: PURPOSE:To make complete corrections over the effective area of each surface by shifting the drive frequency of an optical deflecting element on the basis of results of comparison of output voltages of a reference surface and respective surfaces. CONSTITUTION:A surface M1 is regarded as a reference surface and reflected beam from a reflecting member 41 corresponding to respective surfaces M1-M6 are photodetected by a CCD5, whose output is stored in specific addresses of memories 73 and 74. Digital data corresponding to the surface M1 is read out of the memory 73 repeatedly with the indication of a memory controller 72 and digital data corresponding to the surfaces M1-M6 are read out of the memory 74 synchronously with said read. Then, a drive frequency control circuit 8 calculates difference values between digital data from the memories 73 and 74 and the subtraction results are used as addresses to read correction data which are stored previously in a ROM82. Then, the data is converted by a D/A converter 83 into an analog voltage, which is supplied to a voltage-controlled oscillator 84 to correct the surface tilt angle deviation of each surface, recording scanning lines on a photosensitive recording medium 44 at equal intervals.
