Title: Method and apparatus for testing rectifier of brushless ac dynamotor
Inventor: DEBITSUDO ARAN FUOTSUKUSU
IPC: G01R31/26
Filed: 1988-09-02
Abstract: PURPOSE: To shorten the time required for testing a rectifier by comparing the even harmonics value of the current flowing through the field winding of an exciter with a prescribed value. CONSTITUTION: The output of the armature winding 22 of an exciter is connected to the bridge structure 24 of a rectifier which supplies a rectified current to a main field winding 28 and the field winding 30 of the exciter fitted to a stator is electrically connected to the winding 22. At the time conducting tests, the winding 30 is connected to an AC power source 32 and current signals are generated in lines 36 and 38 by detecting the current to the winding 30 with a resistor 34. When the rectifier 26 is normal, symmetric odd harmonics appear in the detected current, but, when a short circuit occurs in the rectifier 26, a distorted current appears as the even harmonics of the frequency of the applied voltage.  Therefore, the even harmonics component is separated through a BPF 40 and the component is compared with a prescribed reference signal from a line 46 by means of a comparator 44, and then, the operating state signal of the rectifier 26 is obtained from a line 48. Since the rectifier tests can be conducted by stopping a rotor against the generator stator in such a way, the testing time can be shortened.

Title: Method for measuring temperature distribution using nuclear magnetic resonance
Inventor: IMANARI TSUKASA
IPC: G01K7/32
Filed: 1985-10-04
Abstract: PURPOSE:To make it possible to detect the temp. distribution of the cross-section of a matter in a non-contact state, by placing a measuring object in a magnetic field to obtain the gathering data of a free induction decay signal and subsequently applying double Fourier transformation to said data and storing the value corresponding to a specific chemical shift value. CONSTITUTION:A measuring object is arranged in the static magnetic field by a magnet 1 and irradiated with a high frequency pulse having the resonance frequency of an observing nucleus from a surface coil 2. Further, gradient magnetic fields in two directions are applied to said object in a pulsated state from the direction crossing the static magnetic field almost at a right angle by coils 3X-4Y. At a predetermined time after irradiation with the pulse, a free induction decay signal is obtained and stored. This operation is repeated predetermined times while the intensity of each gradient magnetic field is changed to obtain gathering data which is, in turn, subjected to double Fourier transformation. Then, the value corresponding to the chemical shift value of the specific component in position/chemical shift/spectrum intensity data from said transformation is stored in a picture element memory. By this method, the cross-sectional temp. distribution of a living body can be detected in a non-contact state.

IPC: B63H1/28
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a pump jet for ship which takes in water which is not disturbed in an opening at an inlet. SOLUTION: A pump jet for ship has a rotor which is arranged on the upstream and ahead of a rotor drive mechanism. A lower unit 102 of a traction type pump jet has a rotor housing 106 which wraps and surrounds the rotor and a stator housing 108 arranged in the downstream of the rotor and the rotor housing. A drive shaft which is extended from a power head of an outboard motor enters a stator hub in which a pinion gear is engaged with a crown gear attached on a rotor shaft. A rotor drive mechanism is arranged in the downstream of the rotor, and as a result, the rotor becomes a first mechanical element with which water comes into contact first. An opening 114 at an inlet of a pump is larger than an opening at an outlet at an outlet of a stator housing.  Since the rotor is operated by water which is not disturbed, the traction type pump jet is more effective than ordinary pump jet in which the rotor is arranged at a stern of the drive mechanism.
