Title: Buffer memory control system for atm cell speed-converting device
Inventor: TAKAOKA HIDEFUMI
IPC: G06F5/14
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent continuous data error occurrence by detecting that whole FIFOs for constituting a buffer memory become full and resetting whole FIFOs. SOLUTION: A speed-converting part 10 is provided with a reset control part 10B which monitors data quantity inside the buffer memory 10A and erases cell data of the buffer memory 10A, when the data quantity becomes the prescribed one. When writing/reading of cell data is executed in the buffer memory 10A, the reset control part 10B monitors data quantity inside the buffer memory 10A and erases cell data of the buffer memory 10A, when the data quantity becomes the prescribed one. Thus, even when cell data in terms of a burst, which exceed the capacitance of the buffer memory 10A, are inputted, a data error is prevented from continuously occurring, so that efficient ATM (asynchronous transfer mode) coommunication is executed.

Title: Gyrotron tube
Inventor: KIKUNAGA TOSHIYUKI
IPC: H01J25/00
Filed: 1986-07-28
Abstract: PURPOSE:To eliminate the trouble of the electromagnetic wave reflection and to obtain an oscillation property of a designed value, by making one of two dielectrics comprising the window for a gyrotron tube transferrable. CONSTITUTION:A dielectric 1b is rotated along a groove 6 while being brought in tight-contact with the inner wall of an output waveguide 2b. Therefore, the distance between both dielectrics 1a and 1b can be converted by displacing minutely the output waveguide 2b in the axial direction. As a result, by converting the inpedance to an electromagnetic wave of a specific frequency and mode, when looking at the upper side from the lower side of the dielectric 1a, the reflection coefficient of the electromagnetic wave can be converted by the window for a gyrotron tube. Therefore, by regulating minutely the reflection coefficient to the electromagnetic wave of a specific frequency and mode excited in a cavity resonator of the gyotron tube, the Q value of the gyorotron tube can be regulated including the regulation of the reflection of the electromagnetic wave by the said window. As a result, as well as the trouble of the competition of modes can be solved, an optimum oscillation condition can be realized.

Title: Equalizing circuit for communication equipment
Inventor: SAITOU KAZUO
IPC: H04B3/14
Filed: 1981-11-05
Abstract: PURPOSE:To independently and continuously equalize amplitude and group delay distortions, by using a device equalizing the amplitude and a device equalizing the delay characteristics in cascade connection. CONSTITUTION:Signals inputted to a terminal 101 are outputted from a terminal 102 through an amplitude variable equazlizer VAE and variable delay equalizer VDE. The VAE can change the amplitude characteristics only without giving a delay amount. The VDE can change the group delay characteristics only without giving a distortion to the amplitude. Since the amplitude and delay can independently be adjusted in the VAE and VDE, the behavior of the equalization can simply be known. The change in the amplitude depends on the weight coefficient given to signal lines. A plurality of the VAEs and VDEs can be connected.
