Patent JP-S6286201-A (JP)
Title: Method and apparatus for repairing and laying track of railroad
Inventor: FURITSUTSU BIYUURAA
IPC: E01B35/06
Filed: 1986-07-02
Abstract: A levelling and shifting machine and a transmitter system (1) are used, the latter being installed on a carriage parked on the track and transmitting a spreading beam in the horizontal plane for levelling and a spreading beam in the vertical plane (Fr) for shifting, these beams defining an absolute measuring base. The receivers for levelling and shifting, which are installed on a measuring carriage of the machine, are designed for self-centering relative to the line of incidence of one of the said beams or the other during each measurement. In a curve of the track (3), the vertical beam (Fr) defines a cord of this curve, and the set position of the receiver defines the current value of the pitch of the curve (fm0, fm1 etc). A computer calculates the desired value of the pitch (f0, f1 etc.) and the variation (y0, Y1 etc.) between the two values, the latter variation determining the shifting correction. The measuring interval (G') covered by the machine without a change in the position of the transmitter (1) is selected greater than the length (G) of the cord, and the initial measuring point (A0) is selected on the secant passing through the cord beyond the point of intersection of the beam (Fr) and the track (3), so that the sum of the maximum pitches towards one side and the other is compatible with the travel of the receiver on its measuring carriage.

Title: Speed controlling circuit for dc motor
Inventor: KOMINAMI YASUO
IPC: H02P7/288
Filed: 1979-11-30
Abstract: PURPOSE:To heighten a starting torque, by providing a transistor detecting overload condition of a DC motor. CONSTITUTION:A reference voltage generating circuit 11, a voltage comparison circuit 12, an output circuit 13 and a constant current circuit 14 are formed in a monolithic IC to constitute a speed control circuit of a DC motor. As an output of the reference voltage generating circuit 11 generates in input on one side of the voltage comparison current 12 and an output of the output circuit 13 (current mirror circuit) is fed back to an input on the other side of the circuit 12, a DC motor is so controlled that a reverse electromotive force Ea becomes a constant voltage and driven at a constant rotating speed. In the condition that the DC motor is locked like starting time, a voltage between IC terminals (1) and (2) becomes almost zero volt and a transistor Q4 becomes OFF, and therefore, transistors Q2 and Q3 become OFF and ON, respectively, and a starting torque becomes heightened.

Patent JP-H01321815-A (JP)
Title: Inverter protector
Inventor: IMAYANADA AKIO
IPC: H02H7/122
Filed: 1988-06-24
Abstract: PURPOSE:To prevent thermal breakdown of an inverter protector even upon unintended instantaneous overcurrent limit operation by making the operating time limit of an electronic thermal unit shorter than a predetermined value. CONSTITUTION:When an inverter 2 is stopped through function of an instantaneous overcurrent detector 8, output current decreases gradually and when the magnitude thereof deviates from the operating level of the instantaneous overcurrent detector 8, output signal 14 therefrom varies to release temporally interrupted state of a control circuit 5. If the load of an AC motor 4 has not decreased at this time, the current increase again to bring the inverter 2 into interrupted state again. When such state is repeated, output signal 108 from an integrator 103 increases in short time and the sum of the output signal 103 from the integrator 103 and an output signal 107 from an integrator 101 is fed to a comparator 104. When the input reaches to a level set in an overload level setter 106, the comparator 104 makes judgement of overload state and provides an output signal 16 to the control circuit 5 thus stopping operation of the inverter 2.

Title: Video display device
Inventor: JINBA TOMONARI
IPC: H04N19/423
Filed: 1994-07-06
Abstract: PURPOSE:To display the state of a distant place as a picture even when a communication path, which information transmitting amount is limited, is used. CONSTITUTION:A state signal sent from the transmission side is detected by a state signal detecting means 2 and converted into a control signal and based on that control signal, a frame to be displayed is calculated by a display frame calculating means 3. Based on the result, the picture stored in a video storage means 4 is read out and displayed on a video display means 6. Since it is enough to transmit only the state signal to the communication path when the state signal transmitted from the transmission side is made correspondent to the stored contents of the video storage means 4, the desired picture can be displayed even when the information transmitting amount is a little.

IPC: G01B11/02
Filed: 1992-06-15
Abstract: PURPOSE:To provide the non-contact measuring device capable of enhancing the measuring accuracy of a work by correcting the difference of reflectivity between the respective mirrors of a polygon mirror. CONSTITUTION:The offset voltage corresponding to the reflectivities of the respective mirrors of a polygon mirror 18 outputted by an offset voltage forming means constituted of a peak hold circuit 34 are subtracted (offset) from the voltage signal outputted from the measuring part 10 of a work 28 by an operational amplifier 38. This offset voltage signal is converted to a binary signal through zero cross comparison by a comparator 40. By this constitution, the voltage signals different in level outputted from the measuring part 10 can be converted to binary signals of the same level and, therefore, the difference of reflectivity between the respective mirrors of the polygon mirror can be corrected.
