IPC: H01F41/02
Filed: 1990-02-15
Abstract: PURPOSE:To enable the manufacture of uniform laminated inductors, and to prepare the inductors capable of having a large inductance value by small volume by hot-pressing the inductors when the laminated type inductors are baked. CONSTITUTION:Hot-pressing-molding is conducted at pressure of 5-5000kg/cm<2> within a temperature range of 400-900 deg.C, thus obtaining a desired baked body. The difference of shrinkage factors in the baking in a magnetic layer and a conductor section is extremely reduced particularly, thus allowing the manufacture of inductors having complicate patterns which have not been able to be acquired and ultrathin plate type inductors. A sintered body having sufficient baking density can be formed, and the inductors also having excellent mechanical strength in laminates are obtained.

Abstract: PURPOSE:To give the ambience to listeners, by fixing the sound images formed by headphones at a virtual space position which is once decided and controlling the signals fed to both ears in accordance with turns of a body to express a correct virtual space at all times. CONSTITUTION:A base 1 is fixed to a headphone, and a direction mask 5 unified with an azimuth magnet 6 and having a slit 7 at a part is supported rotatably on the base 1. A knob 11 is turned to turn direction correcting stages 2 and 2' after putting headphones on a head and deciding the direction. Thus two photodetecting elements 10 and 10' are set with a good balance at both sides of the slit 7. Under such conditions, the photodetecting quantity and the resistance value are equal to each other between the elements 10 and 10' at the R and L side respectively. Then the head is turned to turn the elements 10 and 10'. However both the magnet 6 and the mask 5 point the south-north direction and have no turn. Therefore the receiving quantity of the photodetecting element has a change, and the resistance value of the element has a change to vary the sound outputs of the R and L sides respectively.

Title: Mixing chamber for low nox
Inventor: MARUYAMA NOBORU
IPC: F23C99/00
Filed: 1989-02-14
Abstract: PURPOSE:To form a favorable mixture of exhaust gas and air drawn in so as to efficiently suppress the formation of NOX by placing an exhaust gas-entry tube inside an air-entry tube connected to an air-entry port and by displacing the exhaust gas-entry port outward from the air-entry port relative to the body of the mixing chamber. CONSTITUTION:A gas-entry port 5 is displaced outward from an air-entry port 2 relative to the chamber body 1 in such a manner that a major-caliber section 6 having the air-entry port 2 as a major diameter is formed at the outer periphery of the gas- entry port 5. Through an exhaust gas-entry tube 4 to a mixing chamber the exhaust gas in an exhaust gas passageway from a heating device 12 is sucked into the chamber body 1 under suction from a combustion device 13 and through air-entry ports 2, 9 outside air is sent in. Since the exhaust gas undergoes a large enlargement loss as it flows from the gas-entry port 5 to the major-caliber section 6, a vertical flow is formed so that the exhaust gas and the air are mixed effectively. The exhaust gas is cooled, as it flows through the exhaust gas-entry 4, by cooling water in a cooling water jacket 8, cooled by air that flows through an air-entry tube 3, and furthermore mixed with air drawn in through the air-entry port 9. As a result, the exhaust gas is cooled to temperatures effective for eliminating NOX.

IPC: H02M7/5387
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide an abnormal load detecting circuit for inverters which detects an abnormal load quickly, and prevents switching elements being important constituents of an inverter from breaking down. SOLUTION: On the occasion of detecting a load while an inverter having self-arc-extinguishing elements whose output frequency is controlled by a phase synchronizing loop is being operated, the phase difference between a voltage V1 and a current I1 to be given to a load is detected by a data flip-flop 53, and an abnormal load signal is sent out on the basis of this phase difference. The variation of its resonance frequency by the abnormal load becomes detectable approximately at the same time with its occurrence by the phase difference of the current I1 and the voltage V1, and breakage of self-arc-extinguishing elements caused by the abnormal load is prevented, before a PLL circuit completes its operation of following the resonance frequency of the load.

Abstract: PURPOSE: To prevent burning of an induction motor at the time of regenerative braking by stopping an inverter when the frequency of the inverter is decreased below the predetermined value.  
     CONSTITUTION: The pulses generated by a pulse generator 17, which is directly coupled to the output shaft of an electric-car-driving induction motor 16 to which power is supplied from an inverter 15, are converted into a voltage signal by an frequency-voltage converter 18. The command signal of a slip-frequency pattern 22 is subtracted from said voltage signal, and a reference oscillator 20 is oscillated. Depending on the oscillated output from the reference oscillator 20, a gate circuit 21 turns the thyristors in the inverter 15 ON and OFF. A stop-frequency pattern 23 and the input to the reference oscillator 20 are compared in a comparator 14. When the fact that the output frequency from the reference oscillator 20 has decreased below the specified value is detected, the output signal generated in the comparator 14 stops the inverter 15, opens a circuit breaker 3, and stops the regenerative braking, thereby the burning  and the like of the induction motor 16 can be previously  prevented.

Title: Line constituting method
Inventor: KURIBAYASHI HITOSHI
IPC: H04B3/00
Filed: 1987-02-18
Abstract: PURPOSE:To attain stable signal transmission and power transmission with low loss to a terminal installation at a remote location by connecting a couple of insulation core wires at both ends of a communication cable respectively so as to suppress the attenuation of a transmission signal and the increase in the DC resistance. CONSTITUTION:A couple of core wires L1, L2 are connected respectively at both ends of a communication cable to form parallel core wires comprising a couple of the core wires L1, L2 in a quad. The core wire is formed in each of the two quads N1 and N51, and the parallel cores P1, P51 are used as forward/return conductors. Through the constitution above, the DC resistance of the conductor is halved and the equivalent distance between the parallel core wires P1, P51 is far larger than the distance between the core wires. Furthermore, the equivalent diameter of the core wires is larger than the diameter of the single core wire because the two core wires are connected in parallel. Thus, the equivalent high frequency resistance and the line capacitance are decreased more than those in using the cores in a single quad, the external inductance is increased and the attenuation constant of the signal gets smaller.
