Title: Redundant data communication system
Inventor: OGAWA TOSHIO
IPC: H04B1/74
Filed: 1983-09-21
Abstract: PURPOSE:To recover automatically redundant communication just after the repair of a faulty system is finished by performing test communication in all stations in order and obtaining successful/unsuccessful information of test when a redundant communication line represents failure information. CONSTITUTION:Stations STi (i=1-n) constituting the decentralized data communication system are connected to a redundant two-way common communication line HF with a couple of couplers Ci. A communication control unit FCA of the ST1 having leadership uses alternately the redundant communication line HF, checks the state of the communication line and each ST to obtain status information and outputs a message corresponding to the information. When the status information of the communication line HF shows fault of a communication line, the communication line at faulty side is used, the test communication is performed in to a normal ST in order to obtain successful/unsuccessful information based on the response of the ST thereto. When successful information is obtained with respect to all tested STs, the redundancy communication is recovered automatically.

Title: Shock tester
Inventor: NAKANO KOZO
IPC: G01M7/08
Filed: 1989-07-06
Abstract: PURPOSE:To generate a shock acceleration waveform which is close to an ideal waveform by providing plural grooves in the side wall of a cylinder and preventing the gas resistance in the cylinder from rising even if the internal capacity of the cylinder decreases. CONSTITUTION:The grooves 13 are formed in the side wall of the cylinder 13. Then when a shock is applied to a piston 14 through a shock head 5, the piston 14 is pressed down in the cylinder 13. Here, the piston 14 is moved down passing the grooves 13a in order since the grooves 13a are provided in the side wall 13a of the cylinder 13. Then as the piston 14 is moved down, gas staying in the groove 13a is discharged to the outside successively and the amount of gas charged in the cylinder 13 decreases. Therefore, even when the internal capacity of the cylinder 13 is reduced by the downward movement of the piston 14, the gas pressure in the cylinder 13 is held constant, a rise in shock acceleration generated in a shock table is suppressed, and the shock acceleration waveform which is closer to the ideal waveform can be obtained.

Filed: 1989-07-05
Abstract: PURPOSE:To eliminate the necessity to previously secure a necessary area in a permanent file by producing a simulated managing table and giving an access to this control table equivalently to a hierarchical structure file. CONSTITUTION:An external storage device 1 is divided into a permanent file area 11 and a temporary file area 12 for the production of the permanent and temporary files respectively.
