Title: Data reception system
Inventor: MAEHARA HIDEJIRO
IPC: H04N1/21
Filed: 1985-06-21
Abstract: PURPOSE:To evade the stoppage of a data reception due to a time-out at a host side by judging whether a space area is left or not in the data reception and performing the data reception, when a data is received beyond a regulated area and after that, by every prescribed bytes at a regulated time interval. CONSTITUTION:When the space area in the data is calculated and it is reduced below half, the interruption of the data reception caused by the sending of the data is prohibited and a timer (low speed reception timer) which generates the interruption with a regulated time interval is started. By the interruption of the timer with a regulated time interval, it is decided whether a request for the reception exists or not and when the reception request for the data exists, the data is received and is stored. By cutting the data reception time with a regulated time interval shorter than a time decided as a device time-out, the device time-out is prevented.

IPC: H03G3/30
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To flexibly handle signals from a continuous high-frequency signal to a short-pulse type high-frequency signal. SOLUTION: This signal level controller distributes a signal of a high frequency band into two by a high-frequency distributor 12 at a predetermined ratio, amplifies one of the distributed signals by an amplifier 13 by passing it through a variable attenuator 13a, distributes the signal into two signals by a coupler 14, and outputs one signal to the outside.  The other signal distributed by the high-frequency distributor 12 is shifted in phase by a phase shifter 16 to match the output phase of the coupler 14 and a balanced mixer 17 mixes the output of the phase shifter 16 and the output of the coupler 14 with each other to speedily judge whether or not the amplitude level of the input signal becomes larger than the amplitude level of the signal amplified by the amplifier 13, i.e., a known set value and when it is judged that the amplitude level is larger, the attenuation quantity of the variable attenuator 13a is so controlled that the amplitude level becomes smaller.

Title: Method for arc-cutting steel material in water
Inventor: SASAKI KOTARO
IPC: G21F9/30
Filed: 1992-05-28
Abstract: PURPOSE:To improve the cutting workability by supplying DC current between an electric power supplying electrode and a position to be cut to generate arc, overlapping AC current to this DC current and reducing the magnetization of the DC magnetized part with the AC magnetization. CONSTITUTION:By generating the arc between the electric power electrode 1 and the position to be cut of a steel material 4 in water, the position to be cut becomes heated molten state by the arc heat, and by dropping and diffusing the produced dross, the cutting range is enlarged. Then, in the case of overlapping the AC current to the DC current, the circumference of electric way of the DC current is DC-magnetized by the generated magnetic field. By conducting the AC current into the same electric way as magnetic way of the DC current, the alternating field is generated in the circumference of the electric way, and by this alternating field, the magnetizing direction is repeatedly changed over and the magnetization is reduced. In this way, cut waste and the dross become the reduced magnetizing condition and the cutting workability is improved because these are not attracted to the cutting position by the magnetization.
