Title: Package control system
IPC: H04L69/14
Filed: 1992-03-10
Abstract: PURPOSE:To shorten the time until a normal operation is obtained and to prevent an artificial failour by using the frame constitution consisting of control data for which package address information and package ID information are added at the time of controlling a slave package by a master package. CONSTITUTION:When the master package 5 controls a slave package 6, the frame consisting of control data for which package address information indicating the packaging position and package ID information indicating the package classification are added is sent from the communication control means 5a of the package 5. The communication control means 6b of the package 6 receives the frame and collates it with package address/ID information managed by a package information management means 6a. The package 6 processes the frame when the package 6 itself is designated, but the package 6 notifyes the package 5 when the package 6 itself is not designated. Consequently, package recognition is automatized, and the time required for restoration to the normal operation is shortened, and an artificial failour is reduced.

Title: Reporting system for registering release miss of incoming service
Inventor: OOSHIMA KENICHI
IPC: H04M3/42
Filed: 1978-04-28
Abstract: PURPOSE:To report the registering release miss of the incoming service by controlling the selector switch of an originating register by a controller on a basis of incoming service registering information in a memory. CONSTITUTION:When subscriber SUB receives the incoming service, controller CC registers subscriber SUB in memory DR on a basis of information obtained by means such as dialing. A prescribed incoming service is performed by CC if incoming is caused for subscriber SUB after that. In case that subscriber SUB issues a calling request under this state, CC detects immediately the state and connects SUB to OR and operates selector switch R to transmit a special tone to subscriber SUB. Therefore, subscriber SUB hears no normal dial tone but the special tone, so that it may be reported that incoming service registering is performed and release is forgotten. CC switches R again after transmitting the special tone for a fprescribed time, so that registering release can be performed.

IPC: F02P5/153
Filed: 1984-03-17
Abstract: PURPOSE:To improve response to knock control as well as operating performance of an engine by detecting the generation of knock and judging the type of the used gasoline and shifting and controlling the characteristics of reference of ignition timing in accordance with the results. CONSTITUTION:Whether knock exists or not is judged by a judging part 2 through an oscillation wave signal from a knock sensor 1. A lag angle controlling voltage generator 3, which is formed by an integrating circuit, integrates a pulse train and raises an output voltage when there is output from a comparator I23. When there is no output, the output voltage is gradually reduced and the ignition timing is subjected to lag angle control to suppress the generation of knock. An operating area judging device 45 obtains information on operating load from a pressure sensor 5 and information on engine speed from an ignition timing controller 7, to form an operating area map. A reference ignition timing shifting controller 4 sets the reference ignition timing to the mode of the type of used gasoline without generating excessive knock when using either of premium or regular gasoline. And, the ignition timing controller 7 automatically shifts to either the lead angle side or the lag angle side.

Abstract: PURPOSE:To securely reduce vibration generated during the operation of a robot at low cost by removing from a control signal a frequency component corresponding to the natural vibration frequency of a robot shaft outputted from a neural network. CONSTITUTION:During the robot operation, a neural network arithmetic part 5 inputs target positions of respective robot shafts J1-J6 outputted from an inverse transformation arithmetic part 2 and sequentially calculates and outputs natural vibration frequencies fn1-fn6 of the respective robot shafts J1-J6. Then a variable notch filter arithmetic part 4 removes a frequency component in a specific range having its center frequency at a notch frequency fN from an inputted signal of a manipulated variable (v) while denoting the natural vibration frequency fn of the controlled system (robot shaft) as the notch frequency fN, and applies the result to a robot shaft driving source in sequence. Consequently, even if the robot attitude changes abruptly, that can be followed up and the vibration that the robot generates is securely removed.

Abstract: PURPOSE:To eliminate the unnecessary spectral peaks resulting from a solvent or the like in the two-dimensional nuclear magnetic resonance measurement, by irradiating a sample with a 180 deg. pulse a given period of time before each irradiation of a pulse train of 90 deg. pulse-tau-180 deg. pulse. CONSTITUTION:When the two-dimensional nuclear magnetic resonance measurement by the Hahn echo method is performed on a system having such homocoupling as <1>H, a pulse train P1 of 90 deg. pulse-tau-180 deg. pulse is supplied to a probe 4 from a generator 1 through a gate 3 and applied to a sample. Then, tau after the irradiation, echo signals are started to be stored in a computer 7 through a processing circuit 5 and an A/D converter 6. Said measurement is repeated a plurality of times with tau varied to perform a two-dimensional Fourier transform. In this case, in advance of the pulse train P1, the sample is irradiated with a 180 deg. pulse P2, and the interval between the 180 deg. pulse P2 and the pulse train P1 is fixed to the relaxation time T1 of the solvent which is desired to eliminate. Thereby, when the 90 deg. pulse is applied, the magnetization of the solvent is not excited at all. Accordingly, the echo signals include no signals resulting from the solvent.
