Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To maintain an oscillation frequency to be fixed, even when voltage fluctuation due to the turning on/off of a power amplifier circuit is generated by supplying a stable voltage from a first regulator to a local oscillator part and supplying the stable voltage from a second regulator to the power amplifier circuit. SOLUTION: A stable voltage VC1 is supplied from a first regulator 11 to a local oscillation part 21, and a stable voltage VC2 is supplied from a second regulator 12 to a power amplifier circuit 222. Even if voltage fluctuations due to the turning on/off of the power amplifier circuit 222 is generated between a transmission slot and a reception slot, it is limited to the voltage fluctuations in the second regulator 12 for supplying the stable voltage VC2 to the power amplifier circuit 222, and the first regulator 11 for supplying the stable voltage VC1 to the local oscillation part 21 is affected only slightly. Thus, the oscillation frequencies fr and ft of the local oscillation part 21 are maintained fixed, transmission is performed through highly accurate modulation, and reception is performed by a low-bit error rate.

Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve real time response to the operation request of retrieval and program searching by providing an auxiliary data accumulation means storing a part of data by the length for maximum waiting time, which is generated in one client device at the time of occupying a data accumulation means. SOLUTION: During the time when the client devices 6-2 to 6-n occupy the data accumulation means 20, the client device 6-1 cannot gain access to the data accumulation means 20. When the operations of title retrieval and program search in the midst of a title are executed in this state through the data accumulation means 20 by the client device 6-1, waiting time is generated. In this case, waiting time is not generated in the client device 6-1 and real time response is improved by reading data for program search and retrieval of the title from the auxiliary data accumulation means 40. The auxiliary data accumulation means 40 previously stores maximum waiting time for one client device.

Title: Piercing roll for seamless steel tube
Inventor: YAMAZAKI MOTOHARU
IPC: B21B27/02
Filed: 1998-12-17
Abstract: PROBLEM TO BE SOLVED: To obtain a steel tube on the inside surface of which lap-ping marks are not generated even when the draft at the tip of a billet is reduced by forming the inlet face angle of a roll having a barrel-shaped body part in two steps and making the poststage face angle larger than the prestage face angle. SOLUTION: In the first half part 2 of the inlet body part of a piercing roll 1 for manufacturing the seamless steel tubes, its face angle α1 is taken as a face angle in such degree that the internal lapping marks are not generated on the inside surface and, in the second half part 3 of the inlet body-part, by making the face angle α2 larger than the face angle α1, the generation of biting failure is prevented. In this way, even when the draft at the tip is taken as larger to such a degree that the internal lapping marks is not generated, the biting failure is not generated. When the inlet face angle of the piercing roll 1 is larger, large rolling force is applied to the billet and the billet is easily bitten with the piercing rolls.  By the arrival of the tip of the billet at the tip of a piercing plug, the billet is greatly reduced and the lapping marks are generated on the inside surface of the tube. When the inlet face angle of the piercing roll 1 is smaller, the large rolling force is not applied to the billet and the biting failure is generated with the piercing rolls.
