Abstract: A line processing module 3 performs processes such as protocol identification, label processing for an associated protocol and in-device address translation for each line. Packet data is stored in a packet memory 5 through high-speed interface macros 2a and 2b based on the in-device address information obtained in the line processing module 3. The in-device address information for all lines is indicated to a scheduler 4 and the scheduler 4 performs scheduling based on the indicated address information. Buffer management if performed for each link and the packet data is read from the packet memory 5 through the high-speed interface macros 2a and 2b. The read packet data is switched in a cross-point switch 6 according to directions from the scheduler 4 and sent back to the line processing module 3, then sent to an output line.

Abstract: In an analog multiplying-averaging circuit for detecting very small mean power in a wide band and a wattmeter using the circuit, a first voltage signal is inputted to a base and a second voltage signal is inputted to a collector of one transistor circuit of a first differential amplifier, to supply a power corresponding to the multiplying-averaging of the two input signals to the collector of the transistor circuit. A base and a collector of another transistor circuit of the first amplifier are grounded to extract a DC collector voltage corresponding to junction temperature differences produced between the two transistor circuits from the collector of the other transistor circuit. A second amplifier is provided, which also has two transistor circuits. A base of one transistor circuit of the second differential amplifier is grounded.

Abstract: In a high velocity gas laser oscillator of radio frequency or microwave exciting type, both end parts of the discharge tube are provided with gas flow rectifiers for making an inward flowing whirlwind at the discharge region of the discharge tube by blowing the discharge gas through plural slits located in a plane disposed at a predetermined angle with respect to a plane including axis of the discharge tube, wherein microwave power is applied to the discharge tube so as to define an annular discharge region in the discharge tube.

Abstract: A method for welding lead wires together by twisting into a strand a plurality of lead wires of electrical parts or the like, producing an arc between the strand and a carbon electrode, thereby melting and welding the strand by the heat from the arc to obtain a weld of high quality.

Abstract: An AC voltage regulator which detects the instantaneous supply voltage in a phase shifter and compares it with the reference voltage by a comparator circuit so that in response to the output signals from the comparator, the firing angle of the thyristors connected to a supply voltage circuit may be controlled in order to maintain constant the effective load current.
