Abstract: PURPOSE:To transfer the section of the line fault and error contents to the center station or the monitor station, by transmitting the test code between stations and by collating this test code with the collation code, in the line monitor device of the carrier multiple communication device. CONSTITUTION:The test code of station A is modulated and is transmitted to station B as the signal of one channel which is not used for communication. In station B, the test code is reproduced and is collated with the code from collation coder 17. If the error is detected, error contents are stored and are read by control circuit 19; and after the station code is added, they are returned to station A and are displayed in station A. Next, the test code is transmitted from station B to station C in monitoring of the line from station B to station C; and if the error is detected in station C, the station code is added to error contents, and they are transmitted to station B. In station B, error information returned from station C is stored after code collation and is read by control circuit 19 and is transmitted to station A, and error information of station C is displayed in station A.

Title: Boring device for fluid tube
Inventor: NAGASE TADAO
IPC: B23B41/08
Filed: 1994-01-25
Abstract: PURPOSE:To improve safety during boring operation by making modification so that a drive shaft is not quickly pushed back even if impact force is applied on a boring tool at the time of completing boring. CONSTITUTION:When boring is started and a fluid tube is pierced through, a boring tool 13 held by the tip of a drive shaft 14 is pushed up by the pressure inside the fluid tube and forced to move upward together with a elevating sleeve 8, which movement is limited by air inside a partition room 39. Because the air inside the partition room 39 is gradually sent out to the open air by a throttle bolt 41, the moving speed of the elevating sleeve 8 and the drive shaft 14 becomes slow and avoids operational hazards.

Title: Device for irradiation test
Inventor: WADA TAKASHI
IPC: G21C17/06
Filed: 1993-02-12
Abstract: PURPOSE:To prevent fretting corrosion and bend distortion of a test fuel element with a device for test irradiation for assembling an uncertain fuel specimen in a reactor and irradiation-testing and safely continue the irradiation. CONSTITUTION:As a plurality of fuel element 1 for testing which is contained in a specimen container, is supported with support projections 11 of a grid spacer 3 and a spiral wire 12 wound on a tie-rod 2, support points in a cross section are shifted each other and all support points never exist in the same cross section. Therefore, in containing the fuel element 1 for testing in the container, no gap between the support points and the fuel element are necessary and so fretting corrosion caused on a fuel element due to the gap can be prevented. Also, owing to the dispersion of the support points, bend distortion of the fuel element and resultant damage of the fuel element can be prevented.

Title: Direct coupling mechanism in variable speed clutch
Inventor: NAGAMITSU HIDEO
IPC: F16D25/12
Filed: 1981-02-20
Abstract: PURPOSE:To aim at automatically making the direct coupling of a multiple- disc clutch of variable speed type upon hydraulic pressure failure by incorporating, in the clutch, a piston for directly coupling the clutch, which is normally biased to the clutch-off side by hydraulic pressure but is moved to the clutch-on side by the bias force of a spring upon hydraulic pressure failure. CONSTITUTION:Hydraulic pressure is normally fed to a hydraulic pressure chamber 20 through a fluid passages 26, 24 so that a direct coupling piston 16 is displaced to the right, overcoming the bias force of a Belleville spring 21, thereby a clutch is held in a clutch-off position. At this stage, hydraulic pressure from a fluid passage 23 does not apply to a pressure chamber 15, and, therefore, a piston 10 is pushed back by a spring 13 so that a pressing part 14 pushes a direct coupling pin 17. The control piston 10 is moved to th left for establishing a clutch-on state when hydraulic pressure is fed to th hydraulic pressure chamber 15 from the fluid passage 23. Since hydraulic pressure in the hydraulic failured, the direct coupling piston 16 is moved by the biasing force of the spring 21 so that the clutch is turned into a clutch-on state by means of the direct coupling pin 17 and the pressing part 14. Thereby, the clutch is automatically coupled, directly, upon hydraulic pressure failure.

Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To suppress bending of an overall fin in the case of forming a louver. SOLUTION: A dimple or wavy plastic deformation mark 300 is formed near bent parts 112a (both end sides of a louver 112c in a cut length wise direction) of the side with small machining amount in association with formation of the louvers through a slit S of both flat surfaces 112b and 212b. Thus, since overall machining amount of a condenser fin 112 becomes substantially equal to that of a radiator fin 212, the part 112a of condenser fin 112 becomes substantially equal to bending R of the bent part 212a of the fin 212 to suppress bending of the integrated fin entirety in a blow shape.
