Title: Coil connecting system of superconductibe electromagnets in superconductive magnetic floating type railways
Inventor: JIZOU YOSHIHIRO
IPC: H01L39/00
Filed: 1978-01-10
Abstract: PURPOSE:To obviate acting of excessive unstable forces to vehicles despite losing of magnetism of one magnet and prevent the occurrence of accidents by electrically serially connecting the on-vehicle superconductive magnets, which give equal effect to vehicle motion, to themselves. CONSTITUTION:In the constitution of on-vehicle superconductive magnets (SCM) 11 thru 1m, 1'1 thru 1'm, 21 thru 2m, 2'1 thru 2'm and track coils 3, 3'. 4, 4', the respective SCMs are fixed to the vehicle body and the respective track coils to the tracks. Here, the SCMs, which are disposed in positions symmetrical to the track center or vehicle centroid are electrically serially connected to themselves, like thrust guide SCMs 11 and 1'1, 12 and 1'2..., and floating ACMs 21 and 2m, 22 and 2'm-1... Then, even if the SCM 11, for instance, causes breakdown of superconduction and loses its magnetism during running, the SCM 1'1 in the position symmetrical thereto is also electrically serial and therefore it simultaneously loses its magnetism, thus acting of unstable forces on the vehicle does not occur. This causes the balance of the vehicle motion to be maintained and enables the serious accident of collision with track coils, etc, to be prevented.

Title: Focus adjusting method for color image receiving tube
Inventor: DOKE HIROAKI
IPC: H04N9/28
Filed: 1990-01-08
Abstract: PURPOSE:To offer an optimum balance of the form of electron beams, and thereby enhance resolution by making use of the difference in the strain sensitivity of the form of the beams between a static convergence correction device provided at the neck section of a color image receiving tube and a dynamic convergence correction device provided for a position close to a pole piece at the emission end of the electron beams. CONSTITUTION:The static convergence correction device 7 of a color image receiving tube is made up out of paired four pole magnets 71 which are magnetized to 4 poles in an annulus ring substrate, and of paired six pole magnets which are magnetized to 6 poles. In this constitution, each magnet 71 is equally intensive to both outside electron beams 10R and 10B, however in order to form magnetic field distribution in the opposite direction, both of the outside electron beams 10R and 10B are therefore moved to the opposite direction. Namely, it is thereby possible that the amount of correction is changed by the opening angle of each magnet 71, and the direction to be corrected is also changed with both of the beams rotated simultaneously. This thereby permits both of the beams 10R and 10B to coincide with each other.

Title: Magnetic recording and reproducing device
Inventor: YANOKURA KAZUHIRO
IPC: H04N5/44
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To automatically turn OFF a power supply in the case that television broadcast is finished at the time of receiving or recording the broadcast by confirming the video signals and the receiving condition, utilizing a synchronous signal and an ATF voltage that are used for selecting a television station and discriminating the presence or the absence of the television broadcast signals in a selected channel. SOLUTION: Since video signals 5 outputted from a tuner 2 are random noises when the broadcast of a selected channel is completed, the signals 5 are not synchronously separated in a synchronously separating circuit 3 and passed to a following stage. A microcomputer 4 discriminates the presence or the absence of synchronization signals 7 and discriminates that no synchronization signal exists. Then, the microcomputer 4 detects an ATF voltage 8, transmits a control signal 9 to the tuner 2, executes a fine adjustment operation against a center frequency and detects a change in the AFT voltage 8. When no television broadcast signal exists, the voltage 8 becomes approximately constant. Then, the microcomputer 4 automatically turns off the power supply after the above two operations are completed.

Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To reduce vibration at the start and stop of an engine by sharply enlarging the operating angle of an inlet cam out of the two units, especially delaying the timing of an inlet valve closing, and installing such a valve as capable of fully closing or opening an inlet port, in the inlet port where the enlarged cam exists. SOLUTION: Only one unit, out of the two inlet cam profiles, is made to correspond to an inlet port 24 as a profile having the closing timing of an inlet valve delayed, and an intake air control valve 25 capable of opening or closing is installed at a side of the inlet port 24. With an ignition turned to ON, the opening of this control valve 25 is checked, and if being closed, it is opened. Subsequently, engine speed is raised up by a motor or the like, starting the spray and ignition of fuel, and if the engine speed is in the specified one, it is so judged that self-operating rotation is started, and thus this intake air control valve 25 is closed. With the control valve 25 operating like that installed, this intake air control valve 25 is usually closed, and idling speed is made maintainable in consequence if the closing timing of one inlet cam profile is delayed.

Title: Integrated matrix switch
Inventor: NAGASHIMA KUNIO
IPC: H04Q3/52
Filed: 1986-01-09
Abstract: PURPOSE:To prevent the fluctuation of a duty ratio due to waveform distortion and a bit error due to cross talk by inserting plural buffers with level reproducing functions into at least one of input and output lines so as to divide the input and output lines into plural parts and permitting the inserted plural buffers to drive the wiring capacities of the divided input and output lines. CONSTITUTION:The ground wiring capacities 111 and 112 are the ones of the input line 400 and the output lines 415, both of which are divided into plural parts, are small compared with a ground wiring capacity in a conventional circuit, and driven by inverters 100 and 104, respectively. The newly added inverters accelerate propagation delay, however the fluctuation of the duty ratio can be prevented, thereby switching a quick signal. If a cross talk component entered to the input line 400 and the output line 415 by inter-wiring capacities 113 and 114 is less than the thresholds of the inverters 101 and 105, their level reproducing functions can remove said component. Thus the fluctuation of the duty ratio due to the ground wiring capacities and the bit errors due to the inter-wiring capacities can be reduced to realize a large matrix size.

Title: Electromagnetic suspension
Inventor: AIKYO HIDEYUKI
IPC: H02K41/025
Filed: 1993-01-11
Abstract: PURPOSE:To provide an electromagnetic suspension which can suppress high-frequency vibrations by providing a magnetic path member which covers the outer peripheral surface and lower end face of a cylindrical electric coil and has openings at its upper and lower ends in corresponding to the upper and lower openings of the suspension. CONSTITUTION:Six sets of electromagnets 11, 21,..., 16, 26 are press-fitted and fixed in the soft-iron cylinder 12 of the suspension 10 and a rod 3 is passed through the center holes of the electromagnets. When alternating currents are supplied to the electromagnets with phase differences, a magnetic field which moves in the length direction is impressed upon the rod 3 and an electric current which acts to stop the moving magnetic field is induced in the rod 3 and a thrust is applied to the rod 3 in the moving direction of the magnetic field due to the interaction between the induced current and moving magnetic field. When the moving direction of the magnetic field is set so that the magnetic field can move from the bottom to the top of the rod 3, the thrust becomes to correspond to a spring force which can support a spring load to a certain extend and the thrust can be adjusted by adjusting the level of the alternating currents. Therefore, a high high-frequency vibration suppressing effect can be obtained, because high-frequency vibrations are suppressed in a self-aligning way.
