Abstract: PURPOSE: To simplify the operability of a filter while in use by making up the filter with such a structure that substances are uniformly coated on the surfaces of fibrous materials and also fibers inside a container are sufficiently opened.  
     CONSTITUTION: After housing opened fibrous materials in a container, a water- soluble coating agent solution, having good affinity to the fibrous materials, is contacted with the fibrous materials, the container itself is treated by a centrifugal separator so as to move the coating agent to the outside of the container by means of centrifugal force in order to remove unnecessary coating agent from the surface of the fibrous materials, and then the fibrous materials with the coating agent are dried to obtain a filter. Thus, the formation of ideal coating layer which is free of the application of external mechanical force and also of delamination and cracking is made possible.

Title: Telephone exchange with incoming call selecting function
Inventor: TATSUMI KAZUHIRO
IPC: H04Q3/58
Filed: 1989-02-21
Abstract: PURPOSE:To allow a called party to select calls optionally and to restrict an incoming call by allowing the called party telephone set to set a caller telephone number whose incoming call is restricted and its time zone. CONSTITUTION:When a called party telephone set 33 applies hook-off, a central controller 6 controls a main switch 1 via a line control circuit 23 to connect the telephone set 33 and a register 5. When the telephone set 33 dials a caller telephone number and its time zone allowing the incoming call in succession to the special number, they are stored in a storage device 7 via the register 5. Thus, when a call comes to the telephone set 33, the controller 6 collates the telephone number and the time zone of a caller telephone set 31 with those stored in the storage device 7 and when they are coincident with each other, the incoming call is accepted. When they are noncoincident, a restriction tone or the like is sent to apply incoming call restriction. Thus, the called party selects calls optionally to regulate the incoming call.
