IPC: H04L1/12
Filed: 1983-07-05
Abstract: PURPOSE:To present the system where a signal resulting from check of control information is returned with less delay after reception, by providing a slave station with a delay circuit, which delays a received signal by a prescribed quantity, and a transfer part which inserts the received signal check result to a prescribed position of the delayed signal.

In the slave station, information is checked in a code monitor part CK in accordance with a conventional method, and the result is obtained after a time corresponding to alpha-number of bits to determine an ACK/NACK signal. Signals corresponding to ACK and NACK are determined preliminarily as ''0'' and ''1'' and are inserted to said space part SP in the transfer part TRN. If the number of bits of the check signal from the master station is (m), (n) and alpha are so selected that n>=m+alpha is true.

Title: High frequency electrode and high frequency transmission line
Inventor: ISHIKAWA YOHEI
IPC: H01P3/00
Filed: 1994-06-03
Abstract: PURPOSE:To reduce the conductor loss and surface resistance of a high frequency electrode and to make application equipment using the electrode into miniaturization and light weight by forming the film thickness of a conductor within a prescribed range. CONSTITUTION:A part of an incident electromagnetic wave advances in the inside of the high frequency electrode, and the other is reflected on the surface of the high frequency electrode.

Title: Substrate surface processing
Inventor: MEGURO TAKESHI
IPC: H01L21/205
Filed: 1990-05-11
Abstract: PURPOSE:To enable the concentration of the uncontrollable impurities such as oxygen and carbon existing on the interface between a substrate surface and substrate layer to be notably reduced by a method wherein an impurity trap layer easier to couple with oxygen and carbon than the substrate is grown and after thermally etching away the trap layer, a layer structure is grown. CONSTITUTION:After the temperature of a GaAs substrate reaches the specific growth temperature, an AlAs layer is grown in thickness exceeding at least 1nm (2 atomic layers). At this time, since the AlAs layer is easier to couple with oxygen and carbon than the GaAs layer, the oxygen in the natural oxide film existing on the surface of the GaAs substrate and the carbon sucking at the GaAs substrate (a) are trapped in the AlAs layer by diffusion. When the GaAs substrate is left at said growing temperature as it is, the AlAs layer is thermally etched away. Thus, the substrate surface becomes excellent GaAs substrate surface containing no oxide film in low carbon concentration and later the objective structure is epitaxially grown. Through these procedures, the excellent epitaxial substrate containing the least impurities (oxide film and carbon) can be formed on the interface between the GaAs substrate and the epitaxial layer.

Abstract: PURPOSE: To improve the precision of tracking the frequency of a signal in a narrow band. CONSTITUTION: An acoustic sensor 1 receives input signals Sin including signals in a narrow band, converts the signals into acoustic signals s1, and transmits the signals s1 to an FFT apparatus 2. The FFT apparatus 2 carriers out frequency analysis at every sampling time T with a constant interval. The results s2 of the frequency analysis for a prescribed time are accumulated in a memory apparatus 3 and the signal intensity distribution s3 in coordinates of time and frequency is computed. Neutral networks (4-1)-(4-k) in K as a total and arranged in parallel one another compute the gradient of the signals in the narrow band in the signal intensity distribution s3 and send the results to an event detecting apparatus 15. The event detecting apparatus 15 compute the maximum point of an output of each neutral network and computes an estimated value dfe of gradient of the event.  At an initial searching, an inclination selecting apparatus 18 sends the estimated value dfe to a frequency estimating apparatus 17 since there is no gradient dfl of a track and the frequency estimating apparatus 17 computes the estimated frequency ϕ and sends it to a track controlling apparatus 16. The track controlling apparatus 16 carries out integration control based on the estimated frequency ϕ.
