Title: Method for flow control of path multiple access system for register insertion transmission
Inventor: IIJIMA AKIO
Filed: 1988-03-22
Abstract: PURPOSE:To cancel an invalid transmission message rejected due to the shortage of a buffer at a reception side and to improve the valid transmission efficiency of a transmission path by making a status frame indicating the number of messages able to receive go round on a transmission path, detecting the number of the status frames and transmitting only when a transmission destination node is able to receive. CONSTITUTION:A node 2 and status frames 5 and 6 of a node 3 are made to go round on the transmission path. When a node 1 is able to receive, the node 1 supervises on a transmission path 4, detects a gap between frames and multiplex-transmits on the transmission path 4 a status frame 7 to indicate the address 'a' of an own node and the number '4' of frames able to receive at the time point. The node 2 detects the status frame 7, when it knows that a transmission is possible, the number of the messages of the status frame 7 able to receive is decreased by the number of transmission messages, transmitted to a downstream, next a message 8 is multiplexed to the node 1 on the transmission path 4 and transmitted. Simultaneously, the node 2 updates the number of the receivable messages of status frame 6 of the own node.

Title: Steam pressure reducing valve with flow rate measuring function
Inventor: MORII TAKAYUKI
IPC: G05D16/16
Filed: 1990-03-15
Abstract: PURPOSE:To omit a separate steam flow rate meter by obtaining the steam dryness by means of the throttling function of a pressure reducing valve and then obtaining the steam flow rate from the steam dryness and the liquid volume. CONSTITUTION:When the dryness X' is measured, the primary steam pressure P1 is detected by a primary pressure sensor 6 attached to a primary pipeline 60 in a stable state of the detection value of a temperature sensor 8. At the same time, the throttled steam pressure P2 passed through a main valve port 14 is detected by a secondary pressure sensor 7. Then a temperature T2 is detected by the sensor 8 respectively. These results of detection are inputted to an arithmetic part part 5. Then the dryness of the steam passed through the port 14 is obtained together with the liquid volume separated by a vapor- liquid separation part 2. Thus the flow rate of the dry steam and the total flow rate are obtained by a flow rate arithmetic means contained in the part 5. As a result, the separate installation of a steam flow rate meter is no needed.

Title: Scanning circuit
Inventor: OZU ITSUO
IPC: H04N5/335
Filed: 1987-03-20
Abstract: PURPOSE:To improve the rise-up speed of a scanning pulse by sufficiently elevating the potential of the control electrode of a transistor (TR) to output the scanning pulse beforehand, through a MOS capacity means, capable of switching. CONSTITUTION:When pulses phis and phi1 are impressed to the main electrode and the gate electrode of the TR M1, and the TR M1 comes to ON, the TRs M2, M3 come to ON because of the potential rise of a point A, and the TRs M2, M3 show a conductance, corresponding to the potential of the point A. Successively, when the pulse phi1 falls, and the inverse of phi1 rises up, the TR M1 comes to OFF, and the inverse of phi1 is impressed to a capacity Cp through the TR M3, and the potential of the point A rises up, and as the result, the TR M2 shows the further higher conductance. When the pulse phi2 rises up in such the condition, because the TR M2 is already in the condition to show the higher conductance, an output pulse with a superior rise-up characteristic appears at an output terminal Out 1 through the TR M2.

Abstract: PURPOSE:To detect a data transmission error efficiently by sending data back in the order of reception from a reception-side processor, comparing the sent- back data with original data by a transmission-side processor, and sending the data back in reverse order from final data to dissident data by the reception-side processor if a dissidence is found. CONSTITUTION:The processor A transfers the data and the processor B stores the received data into a buffer memory 13B and sends the received data back to the processor A in the order of the reception. The processor A compares the sent-back data with the original data when a dissidence is found in the middle of the comparison, the processor A commands the processor B to quit sending the data back. Then the processor B reads the data out of the buffer memory 13B and sends the data back to the processor A in the reverse order from the final data to the dissident data this time. Further, the processor A compares the sent-back data with the original data to decide whether or not the data are transferred normally. Consequently, an error in the data transfer can be detected efficiently.
