Title: Air filter medium and air filter unit
Inventor: KADOTA TOSHIAKI
IPC: B01D46/52
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To obtain an air filter medium producing no harmful effect on the environment and having fine appearance by laminating and integrating a substrate layer made of a colored polyolefin nonwoven fabric and a filter layer made of a polyolefin nonwoven fabric converted into electret. SOLUTION: A substrate layer made of a colored polyolefin nonwoven fabric and a filter layer made of a polyolefin nonwoven fabric converted into electret are laminated and integrated to obtain the objective air filter medium 2. The objective air filter unit is produced using this medium 2. The colored polyolefin nonwoven fabric is, e.g. a colored PP or PE nonwoven fabric. The reason why the colored polyolefin nonwoven fabric is used for the substrate layer is that it is not necessary to impart flame resistance because of self-extinguishability. The reason why the nonwoven fabric converted into electret is used for the filter layer is that fine dust can be captured by static electricity.

Title: Linear actuator
Inventor: KAWABATA FUMIAKI
IPC: F16K31/04
Filed: 1992-01-27
Abstract: PURPOSE:To obtain a linear actuator from which a strong driving force can be obtained without enlarging its size. CONSTITUTION:When electric currents are made to flow through coils 58 and 59, driving forces proportional to the magnitudes of the currents are respectively outputted. Bobbins 50 and 52 and a shaft 32 are moved by the resultant force of the driving forces. When two groove are formed for arranging the coils, the magnetic flux of a closed magnetic path becomes smaller, the saturation of the magnetic flux can be avoided, and the leakage of the magnetic flux can be reduced, because the magnetic reluctance is increased as compared with the case where only one groove is formed. Therefore, the density of the magnetic flux is reduced even when the number of the grooves is increased. On the other hand, by setting the number of the grooves at two, the lengths of the coils can be increased from the conventional example and a strong driving force can be obtained.
