Title: Method for measuring optical loss
Inventor: KITAYAMA KENICHI
IPC: G01M11/00
Filed: 1982-05-04
Abstract: PURPOSE:To measure the optical loss of only the first higher mode in the wavelength region where waves of the fundamental mode and the first higher mode of an optical fiber are guided, by measuring the output of the optical fiber to be measured in the straight state and bending the input end and the output end of the optical fiber to measure the output of the optical fiber. CONSTITUTION:In the region where waves of a fundamental mode LP01 and the first higher mode LP11 of the optical fiber are guided, a bend 5 is given to a fiber 3 to be measured in the end of the incidence of the light from a light source 1, and a ratio of a measured quantity of light in an exit end 7 of the fiber 3 in the state of complete attenuation of the mode LP11 to a measured quantity of light from a cut point just after the bend 5 is operated to measure the optical loss of the mode LP01. First, the bend 5 is not given to the fiber 3 to measure the output power of the exit end 7 in the state where waves of modes LP01 and LP11 are guided, and next, the fiber 3 is cut near the incidence end to measure the output power from the cut point. On a basis of these five measured values, the optical loss of the mode LP11 is obtained by operations.

IPC: F23L17/16
Filed: 1980-06-03
Abstract: PURPOSE: To reduce the temperature of the apparatus and to improve the security of the apparatus by a method wherein a blower which is capable of generating an air stream to produce a downward hot wind and then a combustion air stream due to a negative pressure resulting from the former is provided above a burner.  
     CONSTITUTION: The air stream generated by the fan 2 of the blower arranged above the apparatus produces an air stream A which runs through a gap between an outer cylinder 3 and a wind regulating plate 4 and by an ejector effect due to the velocity of the air stream A, another air stream B is produced with the result that the pressure in a secondary combustion space 11 becomes negative and still another air streams D and E are produced through small holes 10' and 9' which are provided in an inner flame cylinder 10 and an outer flame cylinder 9, respectively. In this case, hot temperature air flows through the center of the apparatus while low temperature air flows outside thereof so that the temperature of the outer cylinder 3 becomes extremely low and the temperature of the wind regulating plate 4 which is subject to a high temperature exhaust gas does not become high as the upper surface thereof is cooled.

Title: Adaptive antenna
Inventor: NAITO TOSHIKATSU
IPC: H01Q3/26
Filed: 1987-03-27
Abstract: PURPOSE:To always improve the D/U ratio independently of the quantity of the level between a desired wave and a disturbance wave by introducing a sum signal and a difference signal of each output of array antenna and outputting either desired signal of them depending on the quantity of the level of the desired wave and the disturbance wave level. CONSTITUTION:When a desired wave D and a disturbance wave U with a lower level than it comes from different directions, the desired wave signal received by antenna elements 1, 1' is controlled so as to be in equal amplitude and opposite phase by weighing circuits 2, 2' and the signals are added by an adder 4. In this case, the level of the difference signal obtained by a subtractor 5 is increased because the desired wave component is added in phase. Two signals of the sum signal and the difference signal are formed as above, and when the desired wave D is smaller than the disturbance wave D, the sum signal is outputted by a changeover switch 6 and on the contrary when the desired wave B is larger than the disturbance wave U, the difference signal is selected and outputted.

IPC: H04L12/42
Filed: 1992-02-26
Abstract: PURPOSE:To provide a clock switching system which can specify a master station that requires no station chaining information with simple constitution when a transmission line has a fault. CONSTITUTION:The slave stations 2 and 4-8 have the information showing the extracting direction of an extracted reference clock (g).

Abstract: PURPOSE:To enhance the manipulatability and the workability for loading and unloading by providing an urging means for changing over a movable frame from a direction in which it is moved to am almost horizontal position into a direction in which loading and unloading is carried out so as to urge the movable frame in order to prevent the movable frame from bouncing up toward the substantially horizontal position at the loading and unloading position. CONSTITUTION:The urging direction line of a dumper stay 50 passes above the rotational center of a hinge member 31, and accordingly, a movable frame 40 is urged counterclockwise. The weights of skis and the movable frame 40 overcome the urging force of the dumper stay 50 so that the movable frame 40 is moved to its substantially horizontal position to a loading and unloading position where it is inclined downward. When the movable frame 40 is moved to the loading and unloading position so as to pass through a position just before the loading and unloading position, the urging direction line of the dumper stay 50 passes from the right to left side of the rotational center of the hinge member 31, and accordingly, the movable frame is urged counterclockwise.

Abstract: PURPOSE:To make it possible to output a surface state information easily while measuring a distance to an object to be measured, by processing a signal representing the signal level of an electric signal from an arithmetic circuit and a control signal so as to deliver a surface state output representing the state of the surface of the object. CONSTITUTION:A control signal 21 from an arithmetic circuit 20 to a light source driving circuit 11A is supplied, together with a signal 22 delivered from the circuit 20 and representing the signal level of an electric signal, to a division circuit in a signal processing circuit 33. Then the division of signal 22/signal 21 is conducted, and further the output of the circuit is differentiated to obtain a surface state output representing a varying point of a surface state. Moreover, the output delayed by a delay circuit and the output left not to be delayed are compared with each other and thereby a further surface state output can be obtained. The output thus obtained is integrated and thereby a surface state output 34 is obtained. By processing the signal 22 delivered from the circuit 20 and representing the signal level of an electric signal and the control signal 22 from the circuit 20 in this way, various parameters representing the distinctive features of variation in the surface state of an object 3 to be measured can be extracted.
