Title: Active noise and vibration controlling device
Inventor: KIMURA TAKESHI
IPC: G05B13/02
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To avoid the divergence of the vibration reduction control by the change in the transfer characteristic accompanying the change in the temperature environment. SOLUTION: When a vibration reduction control is executed under the temperature environment, that differs from an initial condition, in accordance with the updating equation of a filter coefficient Wi, which is set based on the vibration transfer characteristic in the initial condition, the value of a divergence preventing coefficient β, which is contained in the updating equation to stabilize the control, is beforehand set to correspond to the difference between temperature t* of a constant time vibration transfer system and actual temperature (t). Then, the coefficient β, which corresponds to the difference between temperature detection value (t) of the temperature sensor provided in an active type engine mount and beforehand stored temperature t*, is specified based on that correspondence.  Then, the vibration reduction control is conducted in accordance with the updating equation of the coefficient Wi based on the specified coefficient value. Thus, the possibility of divergence in the control is reduced even though the vibration transfer characteristic is changed by the change in the temperature environment and the vibration reduction control is conducted based on a low precision transfer characteristic.

Title: Method and apparatus for network information transfer
Inventor: JIYOERU MAAKU GUURUDO
IPC: G06F13/00
Filed: 1991-06-13
Abstract: PURPOSE: To transfer control information without reserving fixed band at the time of transferring a small amount of data by depriving the band width used for transferring the information from a data transferring mechanism in accordance with a request. CONSTITUTION: When a message is not able to be received normally upon arriving at a destination node 6, information requesting the retransmission of the message can be returned to the source node 1. When a failure occurs in the link used for the transfer of the message, aborting information can be returned without waiting for the end of the message. When the buffer used by the destination node 6 or intermediate nodes 2 or 5 for temporarily storing transmitted data become full of data, the node 6, 2, or 5 can return information for temporarily stopping the data transfer until the overflow of the buffer is solved to the transmission-side node. When the selection of the link used for the message is decided at the beginning of message transfer, information about the usable state of the link can be returned.

Title: Shift serve circuit for recording and/or reproducing head
Inventor: ISHIKAWA KAZUMASA
IPC: G11B21/10
Filed: 1987-07-07
Abstract: PURPOSE:To always obtain constant follow-up displacement quantity by making the gain of a whole servo system including a driving means in the eccentric frequency band of a disk state recording substance nearly uniform. CONSTITUTION:After the low frequency component of a tracking error signal which is impressed to a tracking actuator 1 fetched from an LPF 6 is amplified by an amplifier 11, it is supplied to a driver 7 through an HPF 15 having resistances 12 and 13 and a capacitor 14. Then a shift motor 8 is drived. By properly selecting the constant of each element constituting the LPF 6 and the HPF 15, gain characteristic shown by a figure can be easily obtained by only a circuit system. As this gain characteristic is designed for a compact disk and the rotation frequency of a spindle motor is varied from 3.43-8.65Hz and the eccentric frequency is also the same, the gain characteristic of the shift motor 8 becomes -6dB/oct when the gain characteristic of the circuit system in this zone is set nearly +6dB/oct. As the result of that, the gain characteristic of the whole shift servo system can be made nearly uniform in the eccentric frequency band by putting the gain characteristic of the motor 8 and the circuit system together.

Filed: 1989-06-30
Abstract: PURPOSE:To facilitate maintenance and management by previously storing information required for full printing in the storage memory of a character generation controller. CONSTITUTION:Information required for full printing is previously stored in the storage memory of the character generation controller 4. Based on signals generated from a film position detecting means 2 responding to the traveling of a roll film F, one-dimensional picture elements in an image RAM are outputted to an electric display device 6 via a driving device 5 as ON/OFF of a horizontally deflected signal and a video signal. After that, according to the synchronous signal of a film carrying speed detecting means 3, a one- dimensional picture element display signal synchronous with the roll film F is outputted, and the information is formed on the surface of the roll film F carrying the entire information composed of print characters and symbols. Before an operation stop command is inputted, the sequence is repeated to print it. Consequently, monitoring and confirmation are not needed by more to facilitate maintenance and management.

Title: Bar-code demodulating system
Inventor: KITAGAWA SHIYUNJI
IPC: G06K7/10
Filed: 1979-12-25
Abstract: PURPOSE: To demodulate a bar-code signal with a high precision, by measuring each bit information of a code pattern signal to be demodulated on a basis of the signal width of this code pattern itself.  
     CONSTITUTION: A binary bar-code pattern signal from data extracting part 1 is input to counter 2. Counter 2 counts the time from the rise of each data to the next rise, the time from the fall to the next fall, and the time from the fall to the fall after next and supplies count results to gate 3. Meanwhile, preceding signal width CL 1  is read from counter 2 and is supplied to measure reference signal generating circuits 4 and 5. Reference signals 0.9 times and 1.1 times as long as signal width CL 1  are issued from circuits 4 and 5 respectively and are input to comparing circuit 6 together with next signal width CL 2  from counter. Thus, if signal width CL 2  is within the range of 90W110% of the signal width, gate 3 is opened to store the output of counter 2 into memory 7. For demodulation, the output from memory 7 is demodulated on a basis of signal width CL 2 .
