Title: Boundary element method analyzing device
Inventor: IIZUKA KUNIHIKO
IPC: G06F17/50
Filed: 1989-08-08
Abstract: PURPOSE:To improve the production efficiency of the input data by detecting automatically a salient point where the number of unknown nodal point value is excessive to the number of boundary integration equations and producing automatically the boundary integration equations to fill the satisfactory number of the above equations at the salient point and to obtain the numerical solution of a given partial differential equation. CONSTITUTION:An analyzing data production part 3 obtains the number of unknown nodal point value at the nodal points for each component element of a region to be analyzed based on the input data read by an input data reading part 2. Then a source point is set at a new point excluding the nodal points in accordance with the difference between the number of boundary integration equations obtained by a basic solution defining the relevant nodal point as a source point and the number of unknown nodal point value. Then the data on the set source point is produced. An equation production part 4 produces a boundary integration equation based on the basic solution defining the newly set point as a source point. A solution obtaining part 5 obtains a simultaneous equation of the boundary integration equation defining the new point as a source point and that defining a nodal point as a source point and obtains the numerical solution of a partial differential equation. Thus the input data can be easily produced with improvement of the production efficiency.

Title: Device and method for reducing emi
Inventor: ARNETT DAVID W
IPC: G06F1/10
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for reducing EMI discharged from a computer or any other electronic device. SOLUTION: For example, a clock or any other synchronizing signal is sent from a transmission source to a destination as a double side band suppress carrier wave (DSB-SC) signal. At the transmission source, the amplitude of the clock or other synchronizing signal is modulated by using a wide band low frequency envelope signal. The modulated signal is the DSB-SC signal and this is next sent to the destination beyond a PC board trace. At the destination, the DSB-SC signal is demodulated and the clock or other synchronizing signal is reproduced. At both the transmission source and the destination, the envelope signal can be individually generated from a common key as well.

Title: Solenoid valve
Inventor: BAN TOMOMITSU
IPC: F16K31/06
Filed: 1990-08-04
Abstract: PURPOSE:To increase or decrease the relief pressure to control the relief pressure at any value by screwing an control screw member forward or backward with respect to a member for forming an upstream side passage of a solenoid valve. CONSTITUTION:When a coil 6 is not electrified, a valve 2 is pushed to a cover 3 by the force of a back spring 5 to open the valve 2, and the fluid is flowed from a passage 11a of a control valve 11 to a passage 3b. When the coil 6 is electrified, attraction force to be caused by the electromagnetic force is generated between the valve 2 and a stator 9, and the valve 2 is pushed to a valve seat 14, against the force of the back spring 5, to be closed. A difference of the fluid pressure between an upstream side and a downstream side thereby becomes large, and when a difference of the pressure is larger than the described attraction force, the valve 2 is opened to relieve the fluid. The relief pressure is increased by screwing the control valve forward with respect to the stator 9, and the relief pressure is decreased by screwing the control valve 11 backward. The relief pressure can be thereby controlled at any value.

Title: Priority control system of data bus
Inventor: FUJITA MITSUAKI
IPC: G06F13/374
Filed: 1982-11-26
Abstract: PURPOSE:To make a priority line unnecessary and to determine easily the priority of use, by giving a peculiar priority level to each device and assigning a request line corresponding to the priority level to discriminate the data bus use right. CONSTITUTION:When the necessity of using a data bus 1 arises in a device 2C, the device 2C drives significantly a request line 4C corresponding to the given priority level. The device 2C checks whether request lines 4A and 4B corresponding to priority levels higher than its own priority level are driven significantly or not, and the device 2C uses the bus 1 if they are driven insignificantly, but the device 2C is held if any request line is driven significantly. Since request lines corresponding to priority levels higher than the priority level given to each device are checked to determine whether the bus 1 can be used or not by each device itself when the use right of the bus 1 is determined, the priority line is unnecessary, and the priority is determined easily.
