Title: Packet exchange network
Inventor: SUEMURA TAKEHIKO
IPC: H04L12/931
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a packet exchange network capable of minimizing the length of guard time and enhancing the transmission efficiency of a network without the need for strict adjustment of the length of a transmission line. SOLUTION: In an exchange timing detection in an initial state of a network of this packet exchange network, a reception node 2-0 alternately receives a bit synchronization pattern sent from a transmission node 1-0 and an idle pattern sent from a transmission node 2-1, detects an exchange timing of a packet exchange 3 through the detection of a change point of the patterns and stores the timing. Furthermore, in a delay adjustment operation of this system, the reception node 2-0 detects the packet synchronization pattern sent from the transmission node 1-0 to detect a packet head reception timing. A difference between the exchange timing and the head reception timing is obtained and fed back to a variable delay circuit of the transmission node 1-0 to allow the packet exchange is conducted just in the middle of the guard time.

Title: Control method for internal combustion engine
Inventor: INOUE TADAHIRO
IPC: F02D35/00
Filed: 1980-10-27
Abstract: PURPOSE:To fully exert engine capacity by detecting combustion pressure so as to seek engine torque and by controlling ignition timing, ejection volume, EGR, and transmission ratio so as to produce optimum torque. CONSTITUTION:The output of a pressure sensor 5 installed to each combustion chamber 4 is synchronized to the signal of a crank angle generator 8 through a signal generator and A/D converter 7 and enters a microcomputer 9. The microcomputer 9 obtains an area SA by a pressure increase due to explosion, computes engine torque T, compares T to torque T' of optimum torque map and controls ignition timing, fuel injection volume and EGR volume. The cmputer 9 compares this torque T to transmission point torque for an electronical automatic transmission unit and changes the speed of revolution at the optimum point. The volume of injection is feed-back controlled at T-T' by a two dimensional map when the engine is subject to cold temperature and by an air to fuel ratio sensor when the engine is warming up.

Abstract: PURPOSE:To obtain the optimum voltage for a cell independent from a sense amplifier by defining the maximum voltage of bit lines with the gate voltage of a transistor connecting a bit line and the sense amplifier. CONSTITUTION:The gate of MOS transistors Q1-Qn connecting the respective bit lines of a cell array 10 and the respective sense amplifiers of a sense amplifier group 11 is driven by another power source circuit 17 other than a power source circuit 15 of the sense amplifier group 11 and a power source circuit 16 of a peripheral circuit.

Title: Spectrometric device
Inventor: IIDA ATSUHIRO
IPC: G01J3/28
Filed: 1995-05-23
Abstract: PURPOSE: To enable spectrometry having the same resolution regardless of the placing direction of a sample by correcting spectral intensity data of a two-dimensional lattice-shaped area of the sample by using data of plural small areas in the vicinity of the small area. CONSTITUTION: Three-dimensional data in the X axis, Y axis and wave length direction of a sample is stored in a memory. Data in an optional single wave length is developed and arranged in the X and Y axis direction, and a data value of data Dx ,y is smoothed and corrected by using continuous two every data respectively adjacent in the X axis, Y axis and oblique direction to optional single data, for example, the data Dx ,y , that is, 25 data containing the data Dx ,y . In this case, a weighted factor precalculated on the basis of a difference in vertical dirtectional and horizontal directional resolution is respectively applied to the 25 data.  Therefore, since the vertical directional and horizontal directional resolution of the sample becomes equal to each other regardless of the size and a slit width of a light receiving element, the same spectrometry can be performed on the same small area regardless of the placing direction of the sample.
