Title: Pipe for renewal for lining of existing pipe and execution method for lining existing pipe by using the same
Inventor: OKAMOTO KENSUKE
IPC: B29L23/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To make the outer diameter of a pipe for renewal sufficiently small and to facilitate insertion of the pipe for renewal by forming a part or the whole of the pipe for renewal for lining of an existing pipe by using a plastic foamed body. SOLUTION: A part or the whole of a pipe for renewal for lining of an existing pipe consists of a plastic foamed body and this foamed body has pref. closed-cell structure. In addition, the outer diameter of the pipe for renewal is 2-15% larger than the inner diameter of the existing pipe. In addition, the pipe for renewal is made to be brought into tight contact with the inner face of the existing pipe by contracting the diameter of the pipe for renewal by applying a tensile load in the pipe axial direction of the pipe for renewal and inserting it into the existing pipe and releasing the tensile load to expand the diameter.  Air bubbles are flatted in the longer direction and the pipe for renewal is extended and contracted by making the air bubbles exist in the plastic constituting the wall of the pipe for renewal and applying tensile load in the axial direction of the pipe for renewal. Therefore, even when it is largely extended or contracted, plastic deformation caused by drawing of the plastic itself can be prevented from occurring. It is possible thereby to widen the range for contracting the pipe for renewal without plastic deformation of the foamed plastic.

Title: Portable communication terminal machine and its communication re-connecting system
Inventor: UCHIYAMA TETSUOMI
IPC: H04W92/18
Filed: 1995-05-12
Abstract: PURPOSE: To continue a call again as if communication is not cut by executing a re-calling operation in short time even if communication is cut, automatically making a response again without executing a response operation and re- connecting communication. CONSTITUTION: When a discrimination means 19 discriminates that communication is cut by permitting the user of a portable communication terminal on either a calling-side or an incoming call-side to execute the cut operation of communication, the call is terminated as it is. When the discrimination means 19 discriminates that communication is cut without executing the cut operation, a call control means 20 controls a call means, and the portable communication terminal machine on the calling-side executes the re-calling operation to the portable communication terminal machine of the incoming call-side without accompanying incoming call sound. Thus, the portable communication terminal machine on the incoming call-side, which is re-called, automatically executes a re-response operation so as to re-connect communication even if the response operation by the user is not executed since a response means is controlled by a response control means 21.

Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To reduce the number of parts and lower the manhour in work by providing two ring-shaped magnet fixing members with press-fitting parts, circumferential pressers, and axial pressers. SOLUTION: Since a permanent magnet 2 is fixed inside the insertion hole 11 of a rotor core 1 by means of a circumferential presser 55 and an axial presser 55 by pushing one face of a magnet fixing member 5 against both end faces of a rotor core 1, and adding pressure to a magnetic flux leakage preventive hole 12 thereby inserting it, the permanent magnet 2 can be fixed without an adhesive. Therefore, the permanent magnet 2 can be fixed to the rotor core 2 merely by pressing a magnet fixing member 5 molded integrally to the rotor core 1, so such a problem as the instability of the quality accompanying the bonding work and the increase of the manhour in work can be dissolved. Moreover, heating facilities for using a thermosetting adhesive and an carrying in and takeout device become needless, so the automation of the manufacturing facilities becomes easy.

Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To keep performance of bridge from being monotonous by playing medley section of performance data of a preceding piece of music, and playing medley section of performance data of the next piece of music. SOLUTION: At the time of medley performance, for the first piece of music (preceding piece of music in the drawing), from the head of the piece of music to the last of the medley section (medley L section in the drawing) is read (performed), and for the next piece of music, first bridge data (bridge L data) is read out and subsequently the medley section (medley L section) is read out. In the case where the medley pieces of music further continue, on the end of reading out the medley section, it transits to reading for the next piece of music. In the case where no next piece of music exists and it is the last piece of music, performance is read out to the end (before the bridge data) to end medley performance. Thus, in performing medley of each music piece data, prior to performance of the medley section, a corresponding bridge is performed.
