Patent JP-H09189369-A (JP)
Title: Electrically controllable valve
Inventor: FURIIDORITSUHI MEEGERURE
IPC: B60T8/36
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To reduce the noise in feeding electricity of pulse type to an electromagnet by incorporating a valve opening spring and another spring as return springs directly acting on needle. SOLUTION: When no current is supplied on an exciting coil 13 of a valve 2, a ball valve closed element 8 holds the maximum distance from a valve seat 7 by a valve opening spring 10 and the end part 26 of a control rod 9 is in contact with a needle 16. The second spring 28 and the valve opening spring 10 are tightly contracted into the maximum and the minimum respectively so as to open the valve 2 at maximum. When an exciting current is supplied to an exciting coil 13, the needle 16 pressedly contacts with the control rod 9 and is beaten by the valve opening spring 10 and the spring 28 so that the valve closed element 8 pressedly contacts with the valve seat 7. The spring 28 which is tightly contracted by switching off the exciting coil 13 is made to slide the needle 16 inside of a needle guide pipe 17. Sliding possibility of the control rod 9 is obstructed because of its narrowness of the play in the radial direction between the control rod 9 and a hole 25 for storing it so that the valve closing element 8 is never separated from the valve seat 7 but slowly so as to reduce noise.

Title: Vibrating screen
Inventor: SATO FUMIO
IPC: B07B1/52
Filed: 1991-11-26
Abstract: PURPOSE:To treat a wet powder in the vibrating screen for food, etc., by vibrating a bottomed cylindrical vibrator in which a screening net is laid and providing a compressed air injection nozzle freely rotatably in the vibrator in opposition to the screening net. CONSTITUTION:A particulate matter to be classified is charged to the screening net 8 of a vibrator 3, and a motor 4 is driven to vibrate the vibrator 3. A motor 15 provided with reduction gears is simultaneously driven to rotate a rotating nozzle 22 at low speed. At this time, a diaphragm valve 36 is instantaneously opened at regular time intervals to inject compressed air toward the screen net 8 from the nozzle hole 23 of the rotating nozzle 22, and the particulate matter on the net 8 is shaken down. As a result, the particulate matter on a spring 2 is vibrated, discharged, passed through the mesh, dropped and shaken down. Meanwhile, the clogging of the net 8 is eliminated by the impact of compressed air, and the relative setting angle between the weights 6 and 7 is determined from the property of the particulate matter.

Title: Method and system for acquisition of preferential arterial and venous images for mr angiography
Inventor: FOO THOMAS KWOK-FAH
IPC: G01R33/56
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for preferentially producing separate venous and arterial blood blow images used for MRI angiography. SOLUTION: During a systolic portion of the cardiac cycle, a noise level 50 in the phase image, that is proportional to the velocity encoding value is set at a threshold level above the venous signal 52 but below the arterial signal 54 and a phase contrast MR image that effectively acquires the arterial signal and suppresses the venous signal is acquired. During a cardiac diastolic period of the same R-R interval, the velocity encoding value is then set to establish a noise threshold level 51 in the phase image lower to a value below the venous signal but above the arterial signal to acquire the venous signal and suppress the arterial signal. In this manner, either an arterial only image or a venous only image can be displayed and alternatively, these images can be combined to create higher SNR arterial and venous images.
