Title: Magnetic resonance imaging device
Inventor: FURUI KEIJI
IPC: A61B5/055
Filed: 1990-03-22
Abstract: PURPOSE:To provide a magnetic resonance imaging device the image of which will never be lowered in quality by employing a switching means which interrupts the reference wave for detection during the time when the exciting high frequency pulse is applied by a transmitting circuit system, but yields an output during the time when the magnetic resonance signal is received. CONSTITUTION:A transmitting circuit 2 is made up of a first mixer 2a which applies the reference wave for wave detection to a receiving circuit 4 based on the high frequency wave from a synthesizer 10, and concurrently generates the high frequency pulse carrier wave under the control of a system controller 7, and of a second mixer 2b which generates ther high frequency pulse based on the aforesaid carrying wave fc and a sink function for modulation of an oscillation from the system controller 7. In this case, a switching element interrupts the reference wave for wave detection during the time when the high frequency pulse is applied based on gate signals applied by the system controller 7 by making use of signals which suspends the operation of a power amplifier 11 when no high frequency pulse is outputted, but yields an output during the time when the magnetic resonance signal is received. By this constitution, a magnetic resonance imaging device can be provided, which neither affects the magnetic resonance signal nor lowers its image in quality.

Title: Automatic modem selection system for digital electronic exchange with modem sharing function
Inventor: SHIRATORI AKIHIKO
IPC: H04M3/00
Filed: 1987-03-27
Abstract: PURPOSE:To eliminate the need for operation from a terminal for maintenance by detecting a data modulation speed from an analog audio band signal received from an external modem connected through a pay telephone line and selecting the common-use modem of a corresponding digital electronic exchange for acquisition. CONSTITUTION:When there is an incoming call from an external data terminal 9 to data equipment belonging to a digital electronic exchange, a CPU 5 controls the incoming to its own equipment to set a bus between a central office trunk and an audio band signal receiving circuit 3. Then the circuit 3 receives the analog audio signal of an external modem 8 through a public telephone network and the trunk 2 and a signal speed analyzing circuit 4 detects the data modulation speed as a signal speed according to the received signal. The CPU 5 generates a corresponding common-use modem selection signal according to the detection result and controls a digital channel switch 1 to select the common-use modem automatically, thus eliminating the need for the setting operation of the digital exchanges from the maintenance terminal.

Title: Galloping preventing type overhead transmission line
Inventor: KOYAMA TOSHIO
IPC: H01B7/18
Filed: 1992-02-26
Abstract: PURPOSE:To prevent the galloping vibration of an overhead transmission line by stranding a conductive wire rod with a wire rod having different torsional rigidity. CONSTITUTION:An overhead transmission line is formed of aluminum wires 2 and copper wires 1, having different torsional rigidity therefrom, being stranded therewith so that the copper wire 1 is stranded eccentrically in one part of the outmost layer of the line. As the result, the torsional rigidity changes in a lengthwise direction, so that a torsional natural vibration cycle becomes unstable when ice and snow coat the line, and becomes difficult to synchronize with a natural vibration cycle in an up and down direction. Thereby a galloping vibration can be suppressed by the line itself. Accordingly, it is not necessary to attach a damper having heavy weight to the line, so that the weight loaded on steel towers can be reduced.

CONSTITUTION:When the quantity of received and stored light of each CCD, namely, the quantity of signals of each frequency of jamming waves FJ (F1-F9) during every radar receiving period is as shown in the accompanying Fig. (d), referring to the temporally first radar receiving period T1, the quantity of the signals of each frequency of the jamming wave F1 shown in Fig. 2, (d) is relatively large corresponding to the frequencies F1-F9 (CCD positions A1-A9) and minimum corresponding to the frequency F2 (CCD position A2). That is, the frequency F2 is an LJF. When digital signals with regard to the frequency analysis content of the jamming waves FJ are obtained, by temporarily storing the digital signals at required and comparing the level contents thereof, the LJF for every radar receiving period can be detected.

Abstract: PURPOSE:To avoid an unstable closed operating condition and perturbation to a power system by decelerating a pump or the like after lowering of the opening degree of guide vanes, and by isolating a motor or the like from the power system before the guide vanes are fully closed. CONSTITUTION:A pump or the like 2 is coupled directly to the main shaft of a motor or the like 1, and the rotational speed of the motor or the like 1 is detected by a rotational speed detector 3 and is delivered to an operation control device 4 which therefore determines optimum energizing current value and rotational speed, and delivers control signals to a variable speed control device 5 and a guide vane opening device 6.

Abstract: PURPOSE:To enhance the finishing accuracy of the titled grooves and to easily machine these by projecting a laser beam on a corrosion resistant coating stuck fast to the outside of a work and corroding surface layers of places to be machined whose corrosion resistant coating is removed. CONSTITUTION:In the case of machining the grooves 20 and 22, a corrosion resistant liquid with respect to a corrosive is applied to the outside peripheral surface of the work 10 and dried and solidified and the corrosion resistant coating 12 is stuck fast to the work 10.

The coating of the places 12a and 12b to be machined on which the laser beam 14 is repeatedly projected till the work 10a with the coating is rotated one time is removed. Next, when the work 10 is immersed in the corrosive, the surface layers of the places 12a and 12b to be machined of the work 10 corrode and the grooves 20 and 22 for generating the dynamic pressure are formed. Afterward, the work 10a with the coating is immersed in a peeling agent and a residual part of a coating part is peeled and removed. Accordingly, burrs do not take place on the peripheries of the grooves and the groove bottoms do not become rough and the smooth grooves with the high finishing accuracy are formed.
