Title: Nuclear magnetic resonance imaging apparatus
Inventor: TAKESHIMA HIROTAKA
IPC: G01R33/20
Filed: 1987-09-07
Abstract: PURPOSE:To obtain an inclined magnetic field always having a definite rising/falling time and flatness, by preliminarily storing the optimum current waveform at each intensity of an inclined magnetic field in a memory element and using the corresponding data on the memory element at the time of imaging. CONSTITUTION:A memory element 26 for storing a current waveform is arranged to the pre-stage of a DAC (D/A converter) 21 and the optimum current waveform corresponding to the intensity of each inclined magnetic field is preliminarily stored in said memory element. When a current is allowed to flow to an inclined magnetic field coil, the data of the current waveform corresponding to a necessary inclined magnetic field is drawn out by the order from a sequencer. The data of the memory element is converted to an analogue signal by the DAC while said analogue signal is sent to an amplifier as it is to be applied to the inclined magnetic field coil of load. By this circuit constitution, the optimum current waveform is already obtained in the stage of the memory element and, therefore, it is unnecessary to shape a signal waveform after the DAC. When all of the current waveforms corresponding to the intensity of the inclined magnetic fields necessary for actual measurement are stored in the memory element, an inclined magnetic field having a definite rising/falling time and flatness is obtained without relying on intensity.

Title: Ink jet recorder
Inventor: OKI TOSHIHIKO
IPC: B41J2/175
Filed: 1984-10-23
Abstract: PURPOSE:To locate bubbles at a part other than a nozzle, by a construction wherein the spacing between an ink nozzle plate for ejecting an ink and a base having a driving part for causing the ink to fly is set to be smaller at the periphery of an ink nozzle part than at other part so that the ink is collected at the ink nozzle part under surface tension. CONSTITUTION:With an electric current passed to a heating element 1, an ink 4 is rapidly evaporated on the surface of the element 1 to form a bubble 6, and the ink 4 at the part of a nozzle hole 3a is caused to fly in the form of an ink droplet 5. When the passage of current to the element 1 is cut off, the bubble 6 is externally cooled to disappear, thereby enabling to print again. At this time, an ink is supplied through a supplying passage 2a. When the bubble does not completely disappear after the ink droplet is caused to fly or when an ink containing a bubble is supplied, there is a possibility that a bubble stagnates at the element 1 or the part of the nozzle hole 3a. However, since the periphery of the nozzle hole 3a is narrower than other part, a meniscus 7 and a bubble 8 are formed under the surface tension of the ink at parts other than the element 1 and the nozzle hole 3. Therefore, the part where the bubble is formed by passing an electric current to the element 1 is soon filled with an ink, thereby enabling to print subsequently. The bubble formed is wider on the outside, so that is proceeds in the direction opposite to the flow of the ink and is discharged to the atmosphere.
