Title: Incoming call control system
Inventor: KUWABARA TOSHIO
IPC: H04M3/50
Filed: 1988-09-30
Abstract: PURPOSE:To obtain a simple incoming call control system controlled by means of the will of a called party without any device on a subscriber side by providing a means to control an incoming call according to the request of a called party side in a telephone exchange. CONSTITUTION:When a sender 7 calls a called party 1, the call is connected through a telephone network 6 to a subscriber line exchange 2. When the call is connected, the subscriber line exchange 2 confirms the storage contents of a memory part for the called party 1 in order to know the presence/absence of the registration of the incoming call regulation and whether or not the incoming call is controlled at a present time by a central control unit 5. As a result, when it is judged that the present time is in a time zone to control the incoming call, the central control unit 5 connects the call not to the called party 1, but to an audio response unit 4, and notifies the under-controlling condition of the incoming call to the sender 7. Thus, the simple incoming call control system, which requires any equipment on the subscriber side and is controlled by the will of the called party 1, can be obtained.

Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To form an electrode device for a discharge tube with a glow discharge electrode and an arc discharge electrode, which has a small size and a long life without causing blackening and flickering. SOLUTION: A tubular glow discharge electrode 3 is provided with a slot to accept the end of a supporting conductor 2 and form an opening at the center. The tubular glow discharge electrode 3 has one end welded to the supporting conductor 2 and conductively supported thereby and the other end caulked to the supporting conductor 2 via an insulator 4. Inside the tubular glow discharge electrode 3, an arc discharge electrode is supported at the horizontal tip end of the supporting conductor 2 to carry electron emitted material.  As the tubular glow discharge electrode 3 encircles a filament electrode at a small gap, an electron emitted material evaporated and flied from the arc discharge electrode due to ion impact is immediately trapped and deposited on the inner face of the glow discharge electrode not to be emitted from the glow discharge electrode to the outside so that it can be recycled. In this way, the life of an electrode device is extended.

IPC: H01B7/28
Filed: 1988-09-30
Abstract: PURPOSE:To make it possible to keep humidity resistance of the title wire and cable in a highly radioactive area by applying and baking a water-shutting inorganic paint on the surface of a conductor of an electric wire having an insulator of mainly a glass cloth.
