Title: Threaded joint for piping made of synthetic resin and the like
Inventor: SUGATA HIROBUMI
IPC: F16B33/02
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To make favorable adhesion between a resin and metal to prevent water leak and the like from generating by fitting a high strength external thread reinforcing member of cylindrical body to the extreme end part of a external threaded joint made of a synthetic resin to integrate them. SOLUTION: A high strength external threaded reinforcing member 5 of which the outer part consists of external screw thread part 3 of about 1/3 length from the extreme end of a full screw thread part 2, the inner part is nearly equivalent to the length of the full screw thread part, and the inner diameter of the cylidrical body 4 is equal to the inner diameter of an external threaded joint made of a synthetic resin, is fitted to the part formed with the same cutout as the reinforcing member 5 on the extreme end part of the external threaded joint made of the synthetic resin, and they are integrated to form the external threaded joint 1 of the threaded joint made of the synthetic resin. The external thread reinforcing member 5 is previously formed with undercut 6 so as to favorably join with the resin.  The external threaded joint made of the synthetic resin is formed in this way, and because the about 1/3 part of the center part of the full screw thread part is the synthetic resin threaded part in the external and internal thread, this resin screw thread part is perfectly sealed, and there is no leakage.

Title: Diagnostic method for transmission loop
Inventor: KAJIURA KOICHI
IPC: G08C25/00
Filed: 1990-04-16
Abstract: PURPOSE:To shorten the time required for fault diagnosis by connecting a module part to a transmission loop between a transmitter and a receiving instrument and separating the transmission loop on the side of the transmitter and the transmission loop in the side of the receiving instrument from each other. CONSTITUTION:When the transmission loop between the transmitter 1 and receiving instrument 3 is diagnosed, the module part (slave module part 5 and master module part 6) is connected between them, and the transmission loop on the side of the transmitter 1 and the transmission loop on the side of the receiving instrument 3 are separated and diagnosed respectively. Therefore, if one transmission loop becomes abnormal, a transmission loop wire breaking state and the power-off state of the loop can be discriminated automatically. Consequently, the time required for the diagnosis is shortened.

Abstract: PURPOSE:To constitute an efficient transmission system by constituting so that a transmission line can be divided and connected between specified transmitting divices and between other transmitting devices, when a transmitting device of a transmission system for connecting plural transmitting devices detects that a data transfer quantity between the specified transmitting devices is a large quantity. CONSTITUTION:For instance, a large quantity of information is transmitted between transmitting devices 13, 14. When it is that the transfer is a large quantity, a CPU28 of the transmitting device 13 reports to all transmitting devices that a transmission line 2 is divided. Subsequently, it is stored in a memory 29, and the division of the transmission line 2 is instructed to a controlling circuit part 30.

As a result, the information can be transferred independently, and as for other transmitting devices 6-12, a transmission can be executed between each device. When the transfer between the devices 13, 14 is ended, a connection of the transmission line is instructed to the controlling circuit part 30 by a division information of the memory 29, and the circuit part 30 resets the transmission line 2 to one transmission line.
