Abstract: PURPOSE: To produce a steel plate reduced in the anisotropy of mechanical properties and having high toughness and high tensile strength by applying hot finish rolling to a steel slab of specific composition, excellent in hardenability, under specific temp. conditions and subjecting the resultant rolled steel plate to heating, hardening, and tempering. CONSTITUTION: A slab of a steel, which has a composition containing, by weight, 0.07-0.15% C, 0.02-0.5% Si, 0.4-1.5% Mn, 0.2-0.8% Cu, 0.8-3.5% Ni, 0.2-1.0% Cr, 0.1-1.0% Mo, 0.01-0.1% V, 0.02-0.1% Al, 0.0003-0.002% B, and <0.005% N or further containing specific trace amounts of Ti, Nb, and Ca, is used. This steel slab is heated to 1050-1200 deg.C and rolling is finished at a temp. in the recrystallization region, at >=930 deg.C temp. at one pass prior to the last hot rolling finishing pass, by which a rolled lamellar worked structure can be perfectly recrystallized and the nucleation of a precipitate BN in the worked structure can be inhibited. The resulting rolled steel plate is water- cooled immediately after rolling or is heated to >=Ac3 after cooling and then hardened, followed by tempering at >=Ac1 .  By this method, the steel plate with high tensile strength and high toughness, having a >=780N/mm<2> class tensile strength, can be produced.

Title: Multi-medium communication equipment
Inventor: OTANI MASATOSHI
IPC: H04L5/22
Filed: 1990-04-03
Abstract: PURPOSE:To attain efficient information transfer by detecting relative delay between plural connections at the establishment of plural connections and sending a data with a least delay based on the combination of the delays. CONSTITUTION:A table 102a is referenced and in the case of moving picture information in 62.4k bytes and audio information in 48k bytes, a delay compensation t31 between both media and a connection delay T0 are compared to decide a final medium delay between both the media. In this case, since a same medium is not listed between plural connection delays, the inter-connection delay is not compensated. In the case of t31>T0 based on the final inter-medium delay compensation value, while the audio information is delayed by t31-T0, the information frame is sent, and in the case of t31<T0, while the moving picture information is delayed by T0-t31, the information frame is sent.

Title: Automatic return type fuel-cut system during occurrence of collision
Inventor: SAKAI MAKOTO
IPC: B60K28/14
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To facilitate re-drive of a fuel pump when leakage of fuel does not occur after collision and not to allow re-drive of a fuel pump when fuel leaks. SOLUTION: When, during the occurrence of collision, a collision detecting signal is outputted from a collision detecting sensor 2, an ECU 5 brings a relay 8 into an OFF-state, a fuel pump 12 is brought into a stop, and the feed of fuel from a fuel tank 11 to a fuel pipe 10 is cut off. After a lapse of a given time starting from disconnection of the relay 8, it is decided based on an output from a pressure sensor P whether fuel leaks from the pipe 10. When no fuel leaks, by switching an IG switch to STAR, re-drive of the pump 12 is practicable. When leakage of fuel occurs, re-drive of the pump 12 is blocked through operation of the switch 7. When movement of a vehicle is needed during leakage of fuel, by changing over the switch 7 to START after a reset switch 3 is depressed, re-drive of the pump 12 is practicable. It is displayed at an information device 4 whether fuel leaks.

Title: Call processing using allocation of logic channel
Inventor: TERESA CHIEN IEN WAN
IPC: H04L12/56
Filed: 1993-03-24
Abstract: PURPOSE: To improve the identification method of a communication channel on a communication network using a satellite in an orbit as a network exchange node. CONSTITUTION: A moving device 600 executes communication with the network 116 through the satellite 700. An exchange station 800 is connected to a general telephone exchange network 108. The respective moving devices are managed by the nearby exchange and logic channel identification(LCID) values are allocated. The mobile device and the network identify the device in the network by using the LCID value. The network guarantees that the LCID values addressed to both persons of the call are inserted into all TDMA data packets transferred to both persons. The satellite and the exchange station use the LCID values as logic channel allocation which does not change in the period of the call even if the satellite moves.

Title: Computer system
Inventor: OHASHI TADAHIRO
IPC: G06F11/20
Filed: 1989-04-10
Abstract: PURPOSE:To improve the operation rate of a system by providing a monitor processor which monitors the operation state of a processor and skipping the software loading processing of a stand-by computer for a normally operated management processor. CONSTITUTION:For example, one central processing device 1 is used as the current device, and it is monitored by a monitor processor 5 whether terminal management processors 3 and communication management processors 4 are normal or not. When a stand-by central operation device 2 is raised because of down of the central operation device 1 used as the current device, the processing for management processors which are normal and do not require software loading out of management processors 3 and 4 is skipped. Thus, the time required for rise of the central operation device 2 is shortened by this skip.
