Filed: 1998-10-21
Abstract: PROBLEM TO BE SOLVED: To obtain a streamline plotting method by which a streamline with excellent precision is plotted in an analysis area with a comparatively short time. SOLUTION: In the analysis area (a silicon oxide area 2) of an electric field vector E where a condition that a divergence and rotation are zero is satisfied, a vector E to be vertical in relation is set in the electric field vector E, the vector E is expressed by usage in a stream function Ψ and the Laplace equation of the stream function Ψ is derived. Then the Laplace equation of the stream function Ψ is dissolved under a proper boundary condition, the value of the stream function Ψ at every grid point in the analysis area is obtained through the use of a finite difference method and an finite element method or the like and, then, the isopleth of the value of the stream function Ψ is plotted.

Title: Shuttle device for sewing machine
Inventor: ASANO TAKESHI
IPC: D05B57/14
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a shuttle device for a sewing machine capable of absorbing an impact force generated by a collision between the shuttle stopping part of an inner shuttle and stoppers and reducing a noise attributed to a collision noise generated per rotation of the inner shuttle in a specified range of rotation. SOLUTION: An inner shuttle 1 is stored inside a rotatable outer shuttle 2. The inner shuttle 1 is controlled to a specified narrow range of rotation by a shuttle stopping part 3 and stoppers 9a, 9b on a throat plate 8. A through hole 16 is provided inside the shuttle stopping part 3. Consequently, when the shuttle stopping part 3 comes into contact with the stopper 9b on the throat plate 8, the shuttle stopping part 3 becomes very slightly deformed or bent, and thereby a blowing force generated at the time of a collision between the shuttle stopping part of the inner shuttle and the stoppers, is eased. Thus a radiated noise generated by the impact is lowered.

Title: Detection of signal propagation delay, frame synchronizing method, and moving body communication system
Inventor: NAKAYAMA SATORU
IPC: H04W92/20
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To easily obtain the propagation delay of a signal with a high precision without requiring data collection or the like. SOLUTION: A reception circuit 24 of a slave base station 2 receives the frame signal transmitted from a transmission circuit 13 of a master base station 1 to obtain a reproduced frame signal. A transmission circuit 23 transmits the frame signal of the slave base station 2, which is synchronized with the reproduced frame signal by a synchronizing circuit 25, to the master base station 1. A detection circuit 15 of the master base station 1 compares the reproduced frame signal of the slave base station 2 received by a reception circuit 14 and the frame signal of its own station generated from a timing circuit 17 with each other to detect the deviation between both signals. A CPU 16 obtains the extent of propagation delay in accordance with this deviation and transmits it from the transmission circuit 13 to a CPU 26 through the reception circuit 24 of the slave base station 2.  The CPU 26 sets the received extent of signal propagation delay to the synchronizing signal 25 and synchronizes transmission of the frame signal of the slave base station based on this extent of propagation delay.
