Inventor: SHIGA MICHINORI
IPC: H04L12/40
Filed: 1989-06-22
Abstract: PURPOSE:To prevent the delay in a virtual line establishing time due to the concentration of load to a managing equipment by using the transmission/ reception of a packet between terminal equipment subscribers to establish the communication between an idle terminal connection port and a virtual line, thereby eliminating the need for an idle line managing equipment. CONSTITUTION:A command from a terminal equipment 12a is analyzed by a terminal subscriber equipment 11a and an inquiry broadcast datagram packet is generated and sent. A terminal subscriber equipment 11b analyzes the inquiry packet to generate and send the idle port notice datagram packet. In the case of receiving the notice packet, the terminal subscriber equipment 11a sends a virtual line establishment request packet to the designated address and port in the packet. The terminal subscriber equipment 11b receiving the packet returns a reply packet and a virtual line is established between both terminal subscriber equipments. Thus, no exclusive management equipment is required and the delay in the establishment of the virtual line due to the concentration of the processing to the managing equipment is prevented.

Title: Measuring method based on image recognition and recording medium
Inventor: YOMO HIROMI
IPC: G06T7/00
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method based on image recognition in which the equi-gray level line or the contour of a diffused reflection object having arbitrary shape is extracted stably at high speed and low cost through software processing. SOLUTION: At first, a selection is made between binarization and gray processing and the gray level is designated for an equi-gray level line to be extracted. A pixel value binarization or a cross-section of gray level distribution is found for an objective image at the designated gray level. Subsequently, a relatively large initial floating bubble (processing window frame in local region) is set on the equi-gray level cross-section, the bubble is moved while scanning in order to find an equi-gray level line and a start point is determined by determining an equi-gray level point. Thereafter, the bubble is reduced, a gray processed image/binary image is taken into the bubble, an equi-gray level point is found by judging an equi-gray level line and then an equi- gray level line is determined and the bubble is moved along the equi-gray level line.  The simultaneous processing of smoothing and extraction is repeated until returning back to the start point and the equi-gray level line or the contour is determined from the track of equi-gray level point thus obtained.

Title: Packet exchange control method for packet exchange system
Inventor: OSAKI YOSHIRO
IPC: H04L12/70
Filed: 1988-06-30
Abstract: PURPOSE:To execute a flow suppression control only of an outgoing line in which a congestion is generated without giving any restriction to a packet transmission to the outgoing line in which the congestion is not generated by causing a line housing module to have an exclusive-use communicating medium for the transmission and reception of a transmission packet to a communication line of which it is in charge itself, respectively. CONSTITUTION:To each line housing module unit, an exclusive-use bus is given, and the traffic of the packet in an exchange node is exchanged in a distributed form. When a line sending queuing buffer monitoring part 214 detects the fact that a sending queuing buffer 213 to a line in a line housing module 21a is about to fall into a congested condition, the buffer monitoring part 214 prepares the packet made to have a value for a suppression control as competition control information, and the packet is sent through a bus connection line 91a-1 onto an exclusive-use bus 5-1 of its own until the congestion is canceled. Thus, even when a terminal housing module to send the packet onto the bus exists, a packet transfer is suppressed until the congestion is canceled.

Title: Method and equipment for measuring radiation and monitoring nuclide continuously
Inventor: MAEKAWA TATSUYUKI
IPC: G01T1/36
Filed: 1993-06-30
Abstract: PURPOSE:To allow high sensitivity continuous determination of the concentration of nuclide, dose and variation thereof in the early stage without prolonging the measuring time by determining the radiation information within an arbitrary measuring time width continuously based on the spectral data for at least one section corresponding to the measuring time width. CONSTITUTION:Radiation energy is detected 4 continuously for a measuring time t0 (minimum unit time for detecting the variation) which can be split into a plurality of sections. It is then amplified 5 and subjected to A/D conversion 6 before being recorded in a data recording memory 7. When the radioactive spectral data for L adjacent measuring sections(time t0) is added for each channel to obtain one spectral data, the adjacent L sections are shifted by one data to the next measuring section thus shifting the time axis by the unit time t0. Consequently, the data (shown by black points) can be obtained every unit time t0 while handling data for t0xL time interval and since the concentration variation curve 3 connecting the data points is approximate to an actual concentration variation curve 1, high sensitivity measurement can be realized.

Title: Signal processing circuit
Inventor: OKUBO YUICHI
IPC: H03K23/64
Filed: 1986-07-11
Abstract: PURPOSE:To obtain plural output signals with different frequency division ratios from one input signal and to reduce the power consumption by combining plural frequency division circuits to obtain output signals with different frequency division ratio and stopping the frequency division circuits whose operation is not required depending on the requested frequency division ratio by means of interruption of a bias voltage or the like. CONSTITUTION:In obtaining an output signal Va with a different frequency division ratio, a control signal Vc turns a changeover circuit 13 as shown in dotted lines and a current source of a frequency division circuit 12 is cut off. As soon as the circuit 12 is inactivated, the power consumption is reduced. That is, the control signal Vc acts like a switching control signal and a power supply interruption control signal, and a prescribed timing correlation is regarded as a simultaneous time. Then the output signal Va subjected to 1/M frequency division by a frequency division circuit 11 is fed to the circuit 13. Thus, the output signal Va is obtained as an output signal of the signal processing circuit.
