Title: Power control method and device for telecommunication system using satellite as its basis
Inventor: GARRISON ARTHUR L
IPC: H04B7/195
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an overall power controller that distributes an RF signal power resource of a satellite to lots of earth stations linked with the satellite. SOLUTION: A system operation center 20 distributes a power of a satellite to earth stations 28. Each earth station 28 uses a base band manager 150 to control of a transmission link from a satellite 31 from a BP1 of a beam processor 152 to a specific user terminal, e.g. a terminal 54 through a MODEM M2 and incoming/outgoing links of a channel 62. The MODEM M2 controls transmission power of the satellite through the transmission link 62 to the user terminal so as to allow a receiver of the user terminal 54 to keep a desired S/N. A dynamic power control loop to keep the desired signal quality is provided between the user terminals in the transmission and return links. In order to ensure proper power radiation by the satellite with respect to a feeder link from lots of the earth stations, an output power level of the satellite is automatically controlled.

Title: Electrophotographic device
Inventor: II SHOICHI
IPC: G03G15/08
Filed: 1988-06-15
Abstract: PURPOSE:To maintain an appropriate toner density and to form an excellent image free of fogging by estimating temperature in a device and not replenishing toner when the temperature is low and replenishing toner only when the device is in a temperature environment where the density can be detected correctly. CONSTITUTION:A microcomputer MPU 50 supervises inside the device, and when printing is possible, it sends a heater turning-on signal to a fixing temperature control circuit, and starts a timer until a fixing device 21 reaches a fixing enabled temperature. If the environmental temperature is low when the fixing temperature control circuit 25 outputs the signal indicating fixing feasibility, the MPU 50 neglects a signal outputted from a toner density sensor 36 in a standby state (during agitating a developing device), and controls the operation so that excessive toner is not replenished. On the other hand, if the environmental temperature is high, toner is controlled to be replenished even in the standby state, based on the output signal from the toner density sensor 36. Thus, the toner is maintained at an appropriate density, and a fogging-free excellent image is attained.

Title: Automatic image drawing
Inventor: NODA HIDEO
IPC: B43L13/00
Filed: 1991-05-23
Abstract: PURPOSE:To shorten an image drawing time as a whole by setting a command for rotary movement, considering the circumferential length of a sheet supporting surface so that the sheet supporting surface does not rotate longer than half the circumferential length, in a state where an image drawing device of an image drawing head is in non-contact. CONSTITUTION:The absolute value of movement data from a data processing device 2 is calculated using an absolute value circuit 18 and the obtained absolute value is entered to a comparator 24. Next, a value equivalent to half the circumferential length of a drum is entered to the comparator to determine the difference between the absolute value of the movement data and the value half as much as the circumferential length. On the other hand, the circumferential length is subtracted from the absolute value of the movement data, using a drum rotating direction calculation circuit 22, if the polarity of the movement data is positive, while the absolute value of the movement data is substracted from the circumferential length of the drum using the drum rotating direction calculation circuit 22, if the polarity is negative. The comparator 24 outputs '1', if the calculation result of the comparator 2 is (drum circumferential length/2) < absolute value and an image drawing device is in a non-image drawing state. In addition, an output from an NAND circuit 28 is set to '0' and that from a reversing amplifier 30 is set to '1'. A multiplexer 26 selects an output from the drum rotating direction calculation circuit 22, and a DDA calculation part 26 rotates the drum in an opposite direction to a direction where the movement data rotates.

Title: Evaluating method for metal carrier
Inventor: ISHIKAWA YASUSHI
IPC: G01N19/04
Filed: 1993-06-18
Abstract: PURPOSE:To accurately evaluate a connected state of a metal carrier in a short time by pressurizing the carrier placed on a conical stepped supporting base by a conical stepped punch and detecting a reaction force to be applied to the punch and its moving distance. CONSTITUTION:When a stepped part 7 of a metal carrier 1 for receiving only an outer cylinder 2 and the carrier 1 placed on a conical bearer 6 having a stepped part 8 in which a diameter is reduced by each twice of a wave height of a wavy foil of a honeycomb of the carrier 1 are pressurized from above by a conical punch 9, a shearing force is made to at between layers of the honeycomb. Since its peripheral length approaches an outer diameter, it is larger, and hence a shearing part is increased toward the center. Accordingly, if connected states of the layers of the honeycomb are the same, if it is pressurized by the punch 9, it is sequentially damaged from the center. Then, when a connected part of the pressurized and deformed carrier 1 is observed, propriety of the connected state of the honeycomb can be easily judged. Since a reaction force and a displacement at the time of processing are decided in response to the connected state, a connecting degree can be judged from data of a display recorder 13.

Filed: 1988-06-15
Abstract: PURPOSE:To process a large image and to eliminate the need for a polarizer and an analyzer by composing a target of a semiconductor layer in multiple quantum well structure and a reflecting layer such as Bragg reflecting layer and providing an electron tube which has the target and a partial reflecting mirror. CONSTITUTION:The target 4 is composed of the semiconductor layer 2 in multiple quantum well structure and the reflecting layer 13 such as the Bragg reflecting layer and the electron tube 6 which has the target and the partial reflecting mirror 7 are provided. Then an electron beam emitted by an electron beam 5 forms a charge image of information to be written on the reverse surface of the Bragg reflecting layer 13. Quantum stark effect is caused in the multiple quantum well semiconductor layer 12 by an electric field produced between the charges in the reverse surface of the reflecting layer 13 and a transparent conductive film 3 and this effect shifts the peak wavelength of a absorption by excitons. Thus, the target 4 is composed of the multiple quantum well semiconductor layer which easily have uniform characteristics over wide area and the reflection factor of the target 4 is varied by an external magnetic field. Consequently, the large image can be processed and the need for the polarizer and analyzer is eliminated.
