Title: Manufacture of hot rolled steel or thick plate
Inventor: HANSU PIASHIYAA
IPC: C22F1/10
Filed: 1989-07-28
Abstract: The invention relates to a process for the production of hot rolled strip or heavy plates from stainless and refractory steels or from forgeable alloys on a nickel basis with a final thickness in the range of 5 to 60 mm by the production of a slab from monobloc casting or by continuous casting and heating the slab at a temperature above 1100 DEG  C. followed by the hot rolling of the slab and accelerated cooling of the product rolled to the end thickness. The characterizing feature of the invention is that the heated slab is rolled without interruptions first to a maximum of 1/6 of its initial thickness, mainly by deformation passes in which the degree of deformation pass in the thickness direction is greater than the degrees of deformation shown by curve A in FIG. 1, in dependence on the surface temperature of the product. Then finish rolling is performed to the end thickness, mainly by deformation passes in which the degree of deformation per pass in the thickness direction is greater than the degrees of deformation shown by curve B1 or curve B2 in FIG. 1, in dependence on the surface temperature of the product and the pause between two adjacent passes as parameters. The surface temperature of the finish rolled product must be not less than 1030 DEG  C., if the product contains up to 1.0% molybdenum and not less than 1050 DEG  C., if the product contains more than 1.0% molybdenum. At the latest 100 seconds following finish rolling, the product is cooled at an accelerated rate with a speed in the core of more than 3 K/sec, more particularly more than 5 K/sec, to a temperature which is equal to or lower than 650 DEG  C.

Filed: 1992-06-29
Abstract: PURPOSE:To speedily recognize call incoming even when a user does not stay near a communication equipment by converting a mail address into an extension number by a conversion table provided at a mail server and ringing a relevant pager. CONSTITUTION:A PBX 7 receiving a mail incoming information instruction controls a pager controller 8 and rings the pager corresponding to the extension number set to the instruction.

Title: Automatic linearity adjusting circuit for digital/analog converter
Inventor: MATSUMOTO YOSHIAKI
IPC: H03M1/10
Filed: 1988-08-08
Abstract: PURPOSE:To automatically improve differential non-linearity on the center of an output voltage range of a D/A converter by checking the output voltage of the D/A converter, feeding back the checked result to an adding circuit and controlling the feedback by the most significant bit(MSB) of a digital input signal. CONSTITUTION:The outputs of integrating circuits 6 to 8 are inputted to a voltage generating circuit 9. A DC voltage generated in the circuit 9 is inputted to a 2nd input of the adding circuit 2 through a switch circuit 10 under proper control to bias the output of a D/A converter 1. Since the ON/OFF of the switch circuit 10 is controlled by the MSB of a digital input signal, the DC voltage is impressed to the adding circuit 2 only when the MSB of the digital input signal is '1'. Even when differential non-linearity is generated in the D/A converter 1 when the center of an output voltage range, i.e., an input digital code, is changed from 011...1 to 100...0, the differential non-linearity can be improved by an automatic linearity adjusting circuit.

Title: Channel continuity test method in inter-station common line signal system
Inventor: KOBAYASHI YASUO
IPC: H04M3/26
Filed: 1985-09-04
Abstract: PURPOSE:To decrease connection delay by providing a talking trunk whose channel is formed as a loopback at the idle state to an incoming station to conduct the continuity test without the use of a loopback exclusive trunk thereby reducing the continuity test time. CONSTITUTION:An outgoing exchange control section 1 selects and acquires an idle talking trunk 2 and sends an address signal from a common line signal device 3 to an opposed station and a continuity test trunk 10 is connected to the talking trunk 2 by a switch 8. The continuity test trunk 10 uses the loopback of the talking trunk 7 whose channel is in loopback when the incoming is idle to start the continuity test immediately and when the result is good, the end of the continuity test is informed to the control section 1. The control section 1 uses the switch 8 to open the continuity test trunk 10 to connect a talking path and a good continuity signal COT is sent to an opposite station from the common line signal device 3. In receiving the COT signal at the incoming side, the control section 5 gives a loopback release command to the talking trunk 7 to connect the talking path to the switch 9.
