Title: Electron beam generator
Inventor: SASAKI SHIGEO
IPC: H01J37/30
Filed: 1978-01-24
Abstract: PURPOSE: To prevent the self-breakdown of the electron beam generator at the breakage of the bias power source by connecting both the impulse power source and the bias power source in series to the Wehnelt electrode and giving the minus pole of the bias power source to secure the negative potential to the main cathode at all times.  
     CONSTITUTION: Bias power source 5 and impulse power source 7 are connected in series, and the pulse pole of power source 7 is connected to bar-type main cathode 1 with the minus pole of power source 5 connected to Wehnelt electrode 3 respectively. As a result, electrode 3 always features the negative potential to cathode 1 even though power source 5 is zero. Thus, even in case power source 5 has some breakdown at the generation time of the electron beam, the thermal breakdown can be prevented for anode 4 forming the locus wall of beam 12, the 1st and 2nd electrodes, lens 9 and 11 plus orifice 10.

Title: Digital controller
Inventor: ONO KOJI
IPC: G05B9/02
Filed: 1986-01-17
Abstract: PURPOSE:To suppress runaway of a control ysstem due to the abnormality of ambient environments and a controlled system by providing a selector which switches the output to the controlled system with an error signal outputted by an abnormality detector. CONSTITUTION:An abnormality detector 13 decides the control system to be normal or abnormal in accordance with a controlled system position ]n2 and a controlled variable In5 and outputs an error signal 14. thetan=f(in) is considered between the controlled system position thetan2 and the controlled variable In5, and a forecast output Sn19 of a model estimating circuit 18 is Sn=f(In) based on an obtained nonlinear model of the control system. A comparing circuit 20 compares this output with an allowable error range (e) dependent upon the system, and the control system is decided to be normal to output '0' as an error signal 21 if ¦Sn-]n¦ is smaller than (e), but otherwise, the control system is decided to be '1' as the error signal 21. A selector 5 selects an output 16 of a servo control circuit 12 12 if an error signal 14 is '0', but the selector switches a controlled variable 5 to zero to stop the controlled system if the signal 14 is '1'. Thus, runaway of the control system is suppressed.

Abstract: PURPOSE:To make minimum or avoide a reverse response of a gas turbine output by constructing a gas turbine and a steam turbine as a single shaft coupled construction and absorbing a delayed response operation of the gas turbine by making use of an increased moment of inertia of the coupled construction. CONSTITUTION:Combustion gas 30 of a pressurized fluidized bed boiler 3 is supplied to an expansion turbine 12 through a fuel gas piping 32 after passage of a dust removal device 31 and a precision dust removal device 31 to generate power. A gas turbine 4, a steam turbine 5 and an electric generator 6 are mechanically connected through a shaft, and the power of the expansion turbine 12 serves to drive an air compressor 11 and the electric generator 6. With an increase of moment of inertia caused by the one shaft arrangement of the gas turbine 4 and the steam turbine 5, there can be minimized and absorbed the follow-up of the gas turbine to the electric generator due to the promotion of an in-furnace combustion reaction caused by an increase of the capacity of a pressure vessel of the pressurized fluidized bed boiler upon a change in a load.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To monitor the state of a bank for improving accuracy in the foreseeing of the collapse of the bank by detecting moisture quantity and the moved state of soil through a moisture quantity detecting sensor and an elastic wave detecting sensor which are mutually adjacently buried in the soil. SOLUTION: A moisture quantity detecting sensor 2 and an elastic wave detecting sensor 3 are mutually adjacently buried in the soil of a bank 1. In the case where it rains and a river 4 rises, the moisture quantity inside the bank 1 increases, and the output of the sensor 2 therefore increases. In the case where the earth and sand in the bank 1 move, the output of the sensor 3 increases. The outputs of the sensors 2, 3 are amplified by amplifiers 6a, 6b, and a processing section 7 measures the output of the sensor 2, and a processing section 8 measures the output of the sensor 3, and thus moisture variation and elastic wave variation per unit time are respectively computed.  A processing section 9 combines the variation of moisture inside the bank, the variation of the generated quantity of an elastic wave signal and both the above information to foresee the state of the bank and its collapse, and the result of the above determination is displayed to a display section 10.

Title: Device for detecting displacement of suspension system for vehicle
Inventor: KAMIYA SHIGERU
IPC: B60G17/015
Filed: 1986-01-17
Abstract: PURPOSE:To simplify the constitution of the captioned device by disposing electromagnetic coils respectively on the car body and axle sides of a suspension system to supply cyclically variable exciting current to one coil while induced voltage generated in the other electromagnetic coil is detected. CONSTITUTION:Exciting current of sine wave is supplied from an exciting circuit to an electromagnetic coil 1A. Thus, the exciting coil 1A forms a alternating field to generate induced voltage V in an exciting coil 1B. This induced voltage V is determined by the mutual inductance M12 between change amount dI/dt in the exciting current and the exciting coils 1A, 1B, Since this mutual inductance M12 varies with the distance between the coils 1A, 1B, the distance between the coils 1A, 1B, i.e. the displacement of a suspension system can be detected by detecting the change in the induced voltage V accurately with a simple constitution.

Abstract: PURPOSE: To reduce the instructing time through the production of the program by selecting the operation points of the key positions in each axial direction of the industrial robot featuring the point-to-point (PTP) control system and then memorizing them in the memory.  
     CONSTITUTION: The action of the hands is controlled to the three directions: up- down Z, turning θ and expansion R each, for the PTP control system introducing reproduction type robot. The operation points occupying the key positions in the three axial directions are selected among all action points as the pick-up points. Then only the position data of these points are stored in data memory M 1  to be instructed to the robot. The information of the position data, the velocity, the service code and others of other action points are memorized in action pattern memory M 3  based on the order of the points. Using the data memorized in memory M 3 , the position data in memory M 1  are extracted selectively and then combined each other to be arranged to data memory M 2 . Thus the action program is produced. In such way, the number of the point to be instructed to the robot is decreased, thus reducing greatly the instructing time.

Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To enable a measuring system to be compact, and quickly and accurately measure a rotational speed of a rotary shaft and calculate an acceleration based on the rotational speed. SOLUTION: Through holes 25, 26 of two directions nearly orthogonal to each other are formed to a rotary shaft 22 coupled to a driving shaft. The through holes are orthogonal to an axis of the rotary shaft 22. A light-emitting part 23 and a light-detecting part 24 are arranged outside of parts of the rotary shaft 22 where the through holes are formed. The parts 23, 24 are faced to each other via the rotary shaft 22. A revolution sensor 20 is thus constituted. A light from the light-emitting part 23 passing through the through hole 25 or 26 to reach the light-detecting part 24 is detected during the rotation of the rotary shaft 22 with the use of the revolution sensor 20. A revolution speed of the rotary shaft is measured for every 1/4 rotation on the basis of the detection of the light. Moreover, an acceleration is calculated from measured data of at least two revolution speeds.
