Title: Manufacture of metallic product with hole
Inventor: OKIMOTO KUNIO
IPC: B23K20/00
Filed: 1980-02-14
Abstract: PURPOSE: To easily obtain a metallic product with holes, by arranging and compounding an infiltrating material made of a metal with low melting point in a hole parts on the metallic powder which has already been press mold after being devided so as to easily mold.  
     CONSTITUTION: A pattern for molding material which is difficult to simply mold is flatly divided is as to mold easily and compound. Then, metallic powder such as iron power is filled to said formed metallic patterns and press them to obtain preliminary molding parts 1. Thereafter, a metal with lower melting point than said metallic powder such as, for example, copper, lead, zinc etc. or alloy of them is arranged in a holes of said preliminary molding parts 1. Finally the molds are assembled firmly by holding not to be collapsed and is heated while being pressed in a vacuum. In this way, the molds are strengthened because the metal applied as the infiltrating material 3 around the circumferential surface of the holes is mixed with the mother molding material and at the same time the preliminary mold parts 1 are firmly fixed to each other.

Title: Damper
Inventor: CHIBA KOUICHI
IPC: F16F9/53
Filed: 1979-02-21
Abstract: PURPOSE:To obtain desired damping property with ease in a damper in which a damping action is given by the resistance produced when working fluid passes through an opening by using magnetic fluid as the working fluid and controlling its resistance by a magnetic field generating device. CONSTITUTION:The damping property of this damper fixed by a lower-part blocking board 15 is adjusted against an expected impact load in the following way. First a switch 30 is closed and a coil 21 is electrified to generate a magnetic field within and near a nozzle 19. By this the apparent viscosity of a magnetic fluid 20 found in this part is changed, which results in the change of the damping property. Accordingly, a variable resistance 32 is adjusted so as to obtain the desired damping property. When the impact load 35 acts on a receiving board 25 under the conditions, lower bellows 13 shrink, thereby a part of the magnetic fluid 20 passing through the nozzle 19 with the viscosity set as in the above, thus the desired damping action being produced.

Title: Display control system for attendant board incoming
Inventor: ISHII AKIHIRO
IPC: H04M3/60
Filed: 1983-02-07
Abstract: PURPOSE:To shorten the holding time of a bus and a main processor and to reduce a load by commanding plural attendant boards to perform incoming display simultaneously. CONSTITUTION:When there is an incoming call from a trunk line 7 to a central office trunk 6, a central controller 2 detects this through a bus B1 to analyze the tenant of the trunk 6, the kind of the call, etc., thereby analyzing whether this incoming call is handled by the attendant board 5 of not. When the attendant board 5 is determined, the controller 2 makes a multiple connection between the corresponding attendant board 5 and a data link controller 9 by a time-division multiplex switch 1 to constitute a data link 8. The controller 9 sends incoming display information to respective interfaces 4 through the link 8 on the basis of the command of the controller 2. Each interface 4 discriminates whether the receive information is voice information or control information, and commands incoming display when the information is the control information and addressed to the attendant board 5. Namely, simultaneous control up to the number of connections of the link 8 is performed, so the holding time of the bus and main processor is shortened to reduce the load.
