Title: Supervisory system for restoration from transmission-line-fault
Inventor: NAKAYASHIKI SUSUMU
IPC: H04L12/42
Filed: 1985-04-26
Abstract: PURPOSE:To simplify supervisory procedures of restoring from a fault by so forming the titled system that the detection of the restoring from the fault is able to be executed only by one station with ring-form transmission line that is adjacent to the location of the fault. CONSTITUTION:In case when a fault occurs in the location 9, the neighboring station 1-B returns a signal from a currently using transmission line 2 to a spare line 3 while a station 1-C does it in the opposite direction. Though the station 1-B is transmitting to the station 1-C the signal received through the line 2, this signal does not need to be the said signal, and the signal 1-B is allowed to transmit a supervisory data for restoration from fault. The station 1-C is returning the reception data through the line 2 as it is, to the station 1-B through a transmission line 3. And the station 1-B transmits from its supervisory-data transmission mechanism 7, which is received by a supervisory- data reception mechanism 8 in order to detect the restoration from the fault. The station 1-C also is provided with the same mechanisms as 7 and 8.

Title: Friction joining part of high strength bolt without using patching plate
Inventor: WATABE YOSHIYUKI
IPC: B21H7/14
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain the high slip factor and the high joining proof stress by forming sharp pyramid or conical type roll-forming pattern at the tip part around a bolt hole on either one side of faced friction joining surfaces at the friction joining part of the high strength bolt without using a patching plate. SOLUTION: Hardness at projecting parts with the roll-forming is risen by work hardening to obtain the higher slip factor than the machining method in the same projecting and recessing shape. At the time of roll-forming, a method by using a knurling tool is the simplest. In the case of applying to the joining part without using the patching plate between a gusset plate and a small beam or a brace as members constituting a steel structure, a method for roll-forming around the bolt hole on the flat plate-like joining part by fitting to a drilling machine regardless of a portable type or the one with NC device, is the most desirable. Further, the pyramid type roll-forming pattern is easily obtd. by using the knurling tool combining a nick pattern having some angle.

Abstract: PROBLEM TO BE SOLVED: To set the ID of an extension master without using an ID setting switch and to improve operability by calling a master set from the respective extension masters after an operation and automatically setting the ID numbers to the respective extension masters in the order of a call operation. SOLUTION: When four extension masters are connected to one master, data is transmitted to the respective extension masters ID1-ID4 from the master. When the handset 106 of the extension master 1 is raised and a master call key 109 is depressed, a CPU 110 writes an ID5 into an ID number storage in an EEPROM 115 and transmits master call data by the ID5. When an ID1 is set in an ID number setting memory, the master transmits data for changing the ID number to the ID1 to the extension master 1 of the ID5. Then, ID2-ID4 are sequentially given by executing the similar operation about the other extension master 1.
