SOLUTION: A light amplifier for outgoing line signal 100 is constituted of a first light amplifier 1 amplifying light and a light input level stabilization circuit 13 stabilizing the input level of the first light amplifier 1, for example. A light output control circuit controls a light output, so that a light output level is maintained to a constant level, which is previously decided is installed in the first light amplifier 1. The light output level of signal light, which is outputted from the first optical amplifier 1 and is light-amplifier is controlled to be constant by the light output control circuit. Thus, when the light input level is controlled to be the prescribed level, the interrupt state of signal light of a wavelength in inputted wavelength multiplex signal light can be maintained to an original light amplified state, even if it occurs.

Abstract: PROBLEM TO BE SOLVED: To make it possible for testing equipment to meet DUT different in a module structure by separating a test pattern part proper to a circuit(DUT) to be tested from a test pattern part dependent on a module and by combining them together. SOLUTION: A first pattern generator 50 stores a test pattern part proper to DUT and it generates a start signal 61 to start a second pattern generator 70 and comes to a state of temporary stop until it receives an end signal 62 from the pattern generator 70.

IPC: G06K9/32
Filed: 1985-06-06
Abstract: PURPOSE:To speed up the detecting process of a pattern position even when rough searching is executed by executing pattern recognition in a small area basing on a pattern recognizing position. CONSTITUTION:When the picture data of a field for one picture is stored in a memory 4 for the picture in a period K1, this is detected by an address designating section 7 and a taking-in completion signal b2 is sent out to a CPU 6. On receiving the taking-in signal b2, the CPU 6 opens a multiplexer 8 and sends out the picture data for one picture stored in a memory 4 to a pattern recognizing section 9. Thus, the recognizing section 9 executes the recognition of the pattern picture data from the picture data for one picture basing on the pattern recognizing position information obtained from the picture data of odd number field A, and detects the position. The pattern recognizing process is made in a period K2. Consequently, the pattern recognizing position information obtained by the final pattern recognition is transferred to the CPU 6.

Title: Toner concentration detecting method
Inventor: SUZUKI YOUJI
IPC: G01N11/00
Filed: 1979-09-27
Abstract: PURPOSE:To measure toner concentration by disposing a resistance member in the developer flow passage to generate flow resistance and detecting the displacement of the resistance member owing to the flow resistance with a strain gauge. CONSTITUTION:When the developer is flowed at a constant rate into a housing 1 through a feed port 2, the developer flows like the arrows, but a resistance member 5 is of a conical shape; therefore the developer is condensed near the outflow part 6. Because of this, the developer is rubbed by the resistance member 5, by which flow resistance is generated. The resistance member 5 is displaced downward by this flow resistance and a strain gauge affixing member 3 is displaced by way of a metal wire 4, hence a strain gauge 7 is displaced to generate an output. This flow resistance changes with the concentrations of the developer unless there are no changes in the moving speed of the developer and the shape of the resistance member 5. Hence, the output of the strain gauge 7 changes with the toner concentrations; therefore, the toner concentration may be detected by detecting the output thereof.

Abstract: PURPOSE:To make it possible to vary the distance betwen input and output terminals by reducing a transmission loss, by inserting the internal conductor or a coaxial line from a slit provided in the center or the H surface of a rectangular waveguide that has a resistive terminator connected to its one end. CONSTITUTION:An electromagnetic wave applied to input terminal 1 is transferred to coaxial line 4 via isolator 6 and internal conductor 4a of coaxial line 4 projecting  into rectangular waveguide 3 va in the center of the H surface of rectangular waveguide 3 transmits its energy into rectangular waveguide 3. The electromagnetic  wave transmitted into rectangular waveguide 3 progates in both axial directions of  rectangular waveguide 3; one reaches output terminal 2 by advancing toward output terminal 2, and the other toward resistive terminator 5, so that its energy will  be absorbed. Then, input terminal 1 is moved nearly as much as the length of slit  15 by moving table 7 to vary the distance between input and output terminals.

Title: Automatic charging type copying device
Inventor: HARUHARA IZURU
IPC: G03G21/02
Filed: 1980-09-08
Abstract: PURPOSE:To avoid troubles of money even when a copy is not ejected owing to a fault, by determining whether copying operation is further to be continued or not according to the number of fed sheets of paper, and also by reckoning the amount of thrown money by calculating the remaining amount of money on the basis of the number of ejected copies. CONSTITUTION:As money is entered, the amount of money is set in the register 21 of the 1st arithmetic means 2 and also set in the register 31 of the 2nd arithmetic means 3 as well. The value set in the register 31 is compared with the unit price of a copy by a comparator 33 and when the set value is greater than the unit price, a copy control means 4 makes a copying machine usable. If a fault such as a jam occurs during operation, a fault signal is outputted from the copying-machine control means 4. At this time, when a user requests a change, a change paying means 7 operates to return the amount of money corresponding to the amount in the register 21, i.e., the remainder calculated by subtracting the amount for the ejected number of copies from the amount of money thrown in.
