Title: Attitude controller of antenna on moving object
Inventor: HAYASHI TAKESHI
IPC: G01S3/04
Filed: 1990-11-06
Abstract: PURPOSE:To reduce the number of sensors, reduce an attitude controller mounting space and simplify the attitude correcting calculation by providing attitude change detecting means for detecting a change in the attitude of a moving body in a yaw angle direction, a receiver connected to an antenna and search instruction means. CONSTITUTION:When search is instructed by search instruction means 1 and an antenna Ant is set to take an attitude which is directed toward a radio source, for instance, a geostationary satellite, an attitude correction which interlocks with a change in the direction of movement of a moving body is effected. Thereafter, when the levels of received signals do not reach a proper value level, the antenna Ant is driven within a predetermined range of movement and, when a position where the signals of proper levels are received is found, driving the antenna Ant is stopped in the position. A moving object behavior detecting sensor for such attitude correction as described above is only attitude change detecting means 30 for detecting the change in attitude. Thus, the number of sensors is reduced, attitude correcting calculation and therefore an attitude controller are simplified and the cost can be reduced.

Title: Blood filter
Inventor: MIZOGUCHI KENSAKU
IPC: A61M1/34
Filed: 1999-10-22
Abstract: PROBLEM TO BE SOLVED: To improve the white blood corpuscule-removing performance in a blood filter made of a nonwoven fabric. SOLUTION: A crystalline polymeric fiber the average diameter of which is 1 to 25 μm made of a polyester, polyamide or polyurethane, wherein a groove is provided approx. perpendicularly to the fiber axis by an excimer laser, is formed into a nonwoven fabric. In this case, the depth of the groove is 0.05 to 2 μm, and the width of the groove is 0.2 to 2 μm. Then the nonwoven fabric is laminated to form a blood filter. Compared with a nonwoven fabric without grooves, the fabric with grooves is more excellent in a white blood corpuscule- removing performance.

Title: Shuttle drive device
Inventor: TERADA HIROTOMO
IPC: B41J2/515
Filed: 1986-12-17
Abstract: PURPOSE:To shorten the printing time, by providing a means for determining the inverting position of a shuttle such that the inverting time of shuttle is maintained at a constant level at all times and a means for making inversion control of a drive means based on the result of said inverting position determining means. CONSTITUTION:A shuttle drive comprises a drive means 2 for reciprocating a shuttle 1 in a printing section and a control means 3 for moving the shuttle with a constant speed in a printing section and inverting the shuttle in inverting sections at the opposite ends of the writing section while driving the shuttle with a speed higher than normal drive speed corresponding to the type of character to be printed when printing is carried out. The controller 3 is provided with an inverting position determining means 5 and an inversion control means 6. If the speed of the shuttle is high, the inverting position determining means 5 decelerates the shuttle from in front of the inverting section and determines the inverting section such that the inverting time of shuttle is maintained at a constant level at all times. Since the inversion control means 6 makes inversion control based on said determination, useless time is eliminated from inversion, resulting in the improvement of printing speed.
