Title: Opening monitor for laboratory gas hood sash speed and indicator therefor
Inventor: JACOB STEVEN D
IPC: G01P1/10
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To inform an operator of the fact that a sash is opened at an extremely high speed by alarm by calculating the moving speed of a sash door and generating the alarm signal when the calculated speed exceeds preset speed. SOLUTION: A room controller receives a signal indicating the volume of air exhausted by a gas hood controller 20 and the same signal as that from an exhaust air flow sensor A1 indicating the volume of air exhausted apart from the gas hood exhausted air through a main exhausting system. The room controller calculates the difference between the total flow rate entering to the room and the total flow rate exhausted from the room by the signals. The differential pressure in the room is controlled to slightly lower than that of a reference space outside of the room, to 0.01-0.1inch in hydraulic pressure. When the opening speed of the sash reaches >=1.5feet/sec, audible signal, visible signal or both signals are generated. Based on the intermittent alarm sound generated by the alarm 44, the moving speed of opening sash door is made slow by the operator.

Title: System for measuring magnetostatic field distribution of nuclear magnetic resonance imaging
Inventor: SANO KOICHI
IPC: G01R33/565
Filed: 1985-06-07
Abstract: PURPOSE:To measure the magnetostatic field distribution with one photographing by using a nuclear magnetic resonance (NMR) signal to correct the change of phase due to factors other than the distortion of the magnetostatic field. CONSTITUTION:An NMR imaging device consists of a magnetic field driving part 204 which generates a magnetostatic field, an inclined magnetic field, and a high frequency magnetic field by a control signal from a magnetic field control part 203, a receiver 205 which detects the NMR signal from an object, and a processor 206 which performs the picture reconstituting operation of the detected signal. The interval of time between 90 deg. and 180 deg. pulses generated by the driving part 204 and the interval of between time origins of the 180 deg. pulse and a spin echo signal are made different from each other, and the generated spin echo signal is sampled. The processor performs the picture reconstituting operation including correction processings of the phase deviation due to the receiver 205 and the phase deviation due to the difference of time interval with respect to this sampling signal, and the magnetostatic field distribution is obtained in accordance with relations between the phase variable and the distortion.

Title: Position detecting device
Inventor: KAWAI YASUO
IPC: G01D5/34
Filed: 1979-09-26
Abstract: PURPOSE: To realize the simplification of structure as well as a low cost, by putting the emitted luminous flux into the prism via the part to be detected after distributing both the light emitting element and the photodetector at the same side and then leading the emitted light into the photodetector.  
     CONSTITUTION: The detection part is formed by the wiring substrate 5 provided with the light emitting element 1, photodetector 2 and element cover 4 respectively. The luminous flux emitted from the element 1 goes toward the arrow marking through the luminous flux inlet/outlet 4A. In this case, the luminous flux enters the prism 10 from the light inlet/outlet surface 10C to be reflected on the reflective surface 10A when the prism 10 sealed to the rotor 9 reaches the inlet/outlet 4A. Then the reflected luminous flux is bent toward the arrow marking to go toward the arrow mark through the surface 10C after reflected on the reflective surface 10B, and then enters the element 2 through the luminous flux inlet 4B of the element 2. The time during which the emitted luminous flux reaches the element 2 is equal to the velocity of light and so short that can be neglected. At the same time, the detection part can be packaged compactly onto the substrate 5 along with a reduction of the number of component parts. As a result, the structure can be simplified to realize a cost reduction.

IPC: H02J3/01
Filed: 1995-05-22
Abstract: PURPOSE: To prevent excessive voltage from occurring on the secondary side of a matching transformer by stopping the operation of the active filter with an overvoltage protective circuit and short-circuiting the winding of a matching transformer by switching on a short circuit switch, when the secondary voltage or primary voltage of the matching transformer becomes excessive. CONSTITUTION: If the secondary voltage of a matching transformer 5 becomes excessive by any reason during operation, and the voltage detected through PT21 gets over the specified voltage set in the interior of an overvoltage detecting circuit 22, this outputs an overvoltage signal. A short circuit switch control circuit 23 stops the operation of a controller 8, and also, turns on the thyristor short circuit switch 20 between the matching transformer 5 and an active filter 6 at high speed so as to put zero the secondary impedance of the matching transformer 5. Hereby, the overvoltage generated in an inverter 9 can be prevented.
