Title: Rotation information detector
Inventor: NAGASAWA MASAHITO
IPC: G11B19/28
Filed: 1985-04-29
Abstract: PURPOSE:To obtain an apparatus which permits a smaller size and a lighter weight along with a reduced height of a rotary mechanism section and a thinner deck, by securing both of a speed information signal and a phase information signal with the same mechanism. CONSTITUTION:In a rotation system 1A, an attraction magnet 13 is provided and a disc is attracted securely and turned while a leakage magnetic flux is generated on the same circumference of the disc with a magnet 13 through a higher permeability member 3 provided on the disc with the rotation thereof. Detection means 27 are provided in the form of discs on the opposed surface side of the disc and made up of a plurality of magnetoelectric transducers 28 and 34 which are arranged at an equal space and radially along the circumfer ence thereof to detect the leakage magnetic flux and rotation phase information is obtained at a terminal 37 and rotation speed information at a terminal 38 based on the detection of the leakage magnetic flux varying with the angle of rotation of the disc. Thus, rotation and phase information can be obtained at the same part and by the same detection means in the rotation system 1A thereby simplifying the detection mechanism along with a reduced height of the rotation mechanism section and a thinner deck.

Title: Fuel feed device for internal combustion engine
Inventor: TAKAMARU TAKESHI
IPC: F02M13/08
Filed: 1980-07-09
Abstract: PURPOSE: To obtain the air-fuel mixture of a fixed ratio constantly in a fuel feed device adapted for the alternate use between liquid and gas fuel by delaying the feed of gas fuel for a fixed time when the fuel is changed over from liquid into gas.  
     CONSTITUTION: When natural gas is used for fuel, the fuel evaporized and measured by an vaporizer is introduced from a pipe 2 into a suction passage 4 through a Venturi part 3. On the other hand, when gasoline is used, for example, in a small suction flow, the gasoline measured by a main jet 8 and a low-speed jet 9 is mixed with the air sucked from a low-speed air bleed 11 to be jetted out from a low-speed port 13. At this stage, the needle of a solenoid 15 is faced to the entrane of a low- speed air-fuel mixture passage 12, which is opened for feeding the gasoline. When the fuel feeding is changed over from gasoline into gas, a delay is given for a fixed time by a delay circuit, before the gas fuel is fed into the pipe 2.

Title: Lossless snubber circuit and driving method thereof under the parallel connection of dc chopper
Inventor: NAGAO MICHIHIKO
IPC: H02M3/155
Filed: 1994-03-23
Abstract: PURPOSE:To control a surge voltage and switching loss generated in a DC chopper when the DC chopper is used under the parallel connection by connecting a capacitor between the DC choppers connected in series and alternately driving main switches forming the DC choppers. CONSTITUTION:Diodes D1, D2 are respectively connected in series with main switches Q1, Q2, a capacitor C1 for snubber circuit is connected between the anodes of diodes D1, D2, and two main switch elements Q1, Q2, are alternately turned ON and OFF. Thereby, when the main switch element Q1 (or Q2) is turned OFF from the ON condition, a current flowing in the ON period flows through the capacitor C1 for the snubber circuit after a voltage between the drain and source of the main switch element Q2 (or Q1) which turns ON from the OFF condition becomes zero. Since the current of capacitor C1 for the snubber circuit gradually rises due to the operation of the inductance L1 (or L2), generation of switching loss can be controlled.

IPC: G08G1/015
Filed: 1994-05-02
Abstract: PURPOSE:To provide a vehicle detector using an electrostatic capacity type object detector and capable of improving the accuracy of detection and surely discriminating a vehicle from other objects. CONSTITUTION:When a signal DELTAE is inputted from the electrostatic capacity type object detector 4 to an A/D conversion circuit 11, an analytical processing part 7 executes A/D conversion based upon a clock pulse 18 outputted from a CPU 17. A threshold judging circuit 12 judges whether an output signal from the circuit 11 is more than a previously set threshold or not, and only when the output signal is more than the threshold, stores the data in a memory 13, and when a peak value 15 not generated within a fixed time, judges the state as the influence of rain or humidity and clears the contents of the memory 13. A peak detection circuit 14 detects a peak value out of the data stored in the memory 13 and a time compression circuit 15 normalizes the data. A pattern identifying circuit 16 identifies whether the waveform of the normalized data is a fixed function and the same as a previously recognized vehicle pattern or not.

Title: Preventing method for gas leakage from circumference of tap hole of blast furnace
Inventor: KAWAI TAKANARI
IPC: C21B7/14
Filed: 1979-07-23
Abstract: PURPOSE: To prevent gas leakage from the circumference of the tap hole of a blast furnace, by inserting a lance having a nozzle at its top end into the furnace through the tuyere made just above the tap hole, and by blowing heavy oil compulsively through the lance to the furnace wall corresponding to the tap hole.  
     CONSTITUTION: A lence 10 connected to the top end of a hose 10a for heavy oil is inserted to a tuyere 11. The lance 10 is equipped with a nozzle 12 which faces to the crack 6 made in the circumference of a tap hole 5. The portion through which the lance is inserted is blockaded with blocking material 13. Heavy oil is sprayed at about 10kg/cm 2  pressure in the same manner as in the operation through a nozzle 12. The heavy oil sticks to the inner surface of the refractory material 2 so as to coat it because of its viscosity thereby clogging the cracks 7. The heavy oil burns to form carbide because the inner wall surface of the refractory material 2 is at considerably high temp., and remains at the cracks as it is, so that the leakage of furnace gas is completely prevented.

Title: Optical disk reproduction system
Inventor: NABESHIMA TOMOKI
IPC: G11B7/09
Filed: 1980-07-09
Abstract: PURPOSE: To reproduce information signals stably and securely by exercising tracking servocontrol by wobbling.  
     CONSTITUTION: A reproduced signal obtained through an HPF9 is supplied to a data processing circuit 10 and also to an edge detecting circuit 21 and a latch circuit 22. The edge detecting circuit 21 reproduces and outputs a stable clock signal, synchronizing with the said reproduced signal, through a PLL circuit 23. With this clock signal, the reproduced signal is inputted via a latch circuit 22 and a variable gain amplifier 24 to a substracting circuit 25, which subtracts it from the reproduction output of a photodiode PD8. Consequently, a wobbling component is obtained and inputted to a synchronous detecting circuit 12. An amplifier 24 is brought under feedback control based upon its output and reproduction output. This constitution extracts only the wobbling component securely, so stable tracking control is exercised to reproduce an information signal securely.

Title: Method for diagnosing deterioration of cable
IPC: G01R31/12
Filed: 1992-03-19
Abstract: PURPOSE:To clearly diagnose the degree of deterioration in electric characteristic of the insulator of a high voltage cable with no breakdown by comparing the level of the third harmonic component with the level of a normal cable. CONSTITUTION:A sample cable to be diagnosed is shown as a capacitor Cx, and a standard capacitor for comparision as Cs. A testing high voltage is applied to them from a power source 5 through a protective resistance (r). Then, charge currents flow to them, and the charge currents are inputted to a loss current detecting part 12 through a shelling bridge 11. The detecting part 12 conducts an operation to provide a current component Ir as canceling the current running in the resistance showing the sample cable, and outputs the current Ir to a frequency canalizing part 13 as a loss current. The analyzing part 13 conducts the frequency analyzing processing of the loss current and displays a graph showing the analysis result. Since the level of a third harmonic component C3 of the graph satisfactorily follows the degree of deterioration of a cable insulator, the degree of deterioration can be judged.
