Abstract: PURPOSE:To make the line setting of a satellite communication system optimum in a simple method to improve the availability of each line by controlling the transmission power of each station so that the line quality between stations may always agree with a given reference value. CONSTITUTION:In case that three communications between earth stations A and B, C and D, and E and F are amplified commonly by satellite relay 1, the line quality of A B is improved and the line quality of B A, C D, C D, E F, and E F is deteriorated slightly when the transmission power of station A is increased. Meanwhile, the transmission power of only station B is increased, the line qulity of B A is improved and the line quality of other lines is deteriorated slightly. Consequently, an optimum line setting is obtained when line qualities of A B and B  are equal to each other, and a reference value for line quality is so given that they may be equal to each other. Then, the local transmission power is controlled on a basis of line qualities in both ways measured in station A or B, and line qualities in both ways measured in station A or B, and line qualities in both ways are made agree with the reference value.

Title: Suction cleaner and operating method thereof
Inventor: OHARAGI HARUO
IPC: A47L9/19
Filed: 1991-01-29
Abstract: PURPOSE:To accurately determine the lock of a rotary brush and to protect a nozzle motor, by a method wherein when output from a current-detecting circuit is beyond a first preset value, voltage applied to the nozzle motor is lowered by regulating a phase-control angle therefor, and when the output is beyond a second preset value, it is determined that the rotary brush is locked and the operation of the nozzle motor is stopped. CONSTITUTION:When a rotary brush 10 is locked, a mean value of detected voltage is suddenly increased by the work of a peak-holding circuit. At this time, if the mean value at a first preset value or above is continuously detected for a first preset time or above, it is decided that the rotary brush 10 is being in the state of locking. When it is determined that the rotary brush 10 is being in the state of locking, a phase-control angle is made large and voltage applied to a nozzle motor 26 is lowered. After that, the mean value at a second preset value or above is continuously detected for a second preset time or above, it is determined that the rotary brush 10 is locked and the operation of the nozzle motor 26 is stopped.

IPC: A47L9/28
Filed: 1994-01-31
Abstract: PURPOSE:To provide economical and effective operation by regulating an ignition phase angle to keep a signal level of a current detection means constant for controlling an input to a motor-driven blower to be kept constant. CONSTITUTION:When a vacuum cleaner is operated, a phase angle for ignition of a TRIAC 35 is determined based on a signal from a hand operation part 15 for controlling an input to a motor-driven blower 2. A reference value (a current command value) is determined to control a signal level of a current detection means 31 to be kept constant based on a signal from the hand operation part 15. Next, the motor-driven blower 2 is controlled in such a way that the signal level of the current detection means 31 is kept constant by a phase control means 33 based on the determined current command value. Quantity of dust in a dust collecting chamber 11 is thus increased, for example, to decrease load on the motor-driven blower 2, and when the current value is lowered, the output signal level of the current detection means 31 is lowered, in which case the phase firing angle is increased to return the current value of the motor-driven blower 2 to the previous level.

Title: Photodetector
Inventor: NAKAMURA KENJI
IPC: G01J1/02
Filed: 1989-01-18
Abstract: PURPOSE:To respond to an incident light at an ultrahigh speed by scattering carrier to be ballistically conducted in intrinsic semiconductor by optically pumped carrier to cause current change. CONSTITUTION:A voltage of an appropriate amplitude is applied between N-type AlGaAs layers 3, 5 through electrodes 6, 7 by an external circuit, electrons fed via the electrode 7 are passed through the N-type AlGaAs layer 5, accelerated by the voltage in an I-type GaAs layer 4, and ballistically conducted in the I-type GaAs layer 4. Optically pumped carrier is generated in the I-type GaAs layer 4 as charge having zero average initial speed. Accordingly, electrons 14 to be ballistically conducted are scattered by coulomb force. Since the scattering occurs on the way in the I-type GaAs layer, this current change is transmitted to the N-type AlGaAs layer 3 for a shorter period of time than the time in which the electrons to be ballistically conducted are passed through the whole I-type GaAs layer, and transmitted to an external circuit. Thus, a photodetector having a high speed rising time is obtained.
