Abstract:
PURPOSE:Powders of glass material resulting from gas phase reaction are made into a suspension using a sprayed liquid and collected for drying, thus obtaining efficiently soot with large bulk density using miniaturized vessels and units. CONSTITUTION:While the liquid raw materials are carried from vessel 1 by bubbling argon gas, oxygen gas is mixed in tube 3 and the mixture is introduced through tube 3 to one of the inlets for oxyhydrogen flame burner 4. Hydrogen is sent to another inlet and the flame hydrolysis is effected by the flame 5 to form oxide soot 6. Liquid 9 is sprayed from sprayer 8 around vessel 7 into the vessel to collect the soot 6a in the bottom of the vessel without flyloss as a temporary dispesion 10. The dispersion 10 is made to flow down through tube 11 into vessel for drying 12, heated by heater 13 and gradually dried to accumulate soot.

Abstract:
PURPOSE: To make nonuniformity of luminance small by a method wherein a whole region of an output characteristic curve is unequally divided by adapting to an input/output characteristic of an infrared detector element and output data is corrected by output data of a reference infrared detector element corresponding to output data at upper and lower end in the divided region including the output data. CONSTITUTION: In a graph of an output of an infrared detector element, i.e., image data of (i) pixel and image data of a preset reference pixel, an unequally divided scale in which both end sections are narrowed and non-linear characteristic is represented thereby is provided to an ordinate on the left side of an equally divided scale in addition thereto. When image data Idj marked by a symbol (x) is inputted, corresponding low order boundary value data L, a width dHL and a low order boundary value gj in an unequal region are read out from a ROM by addressing a corresponding low order boundary value mj in an equal region. Corresponding reference image data sj (gj ), sj (gj +1) is read out from another ROM by addressing the boundary value gj and a low order boundary value gj +1 upper by dHL therefrom, then calculation is executed according to an equation to obtain correction data.
Abstract:
PURPOSE:To prevent an output state after correction from fluctuation by selecting one of all detecting elements of a detector as a representative element, adjusting the sensitivity of all the detecting element to the sensitivity of the representative element, and correcting detection data obtained by the respective detecting elements at the time of image pickup operation. CONSTITUTION:Temporary detection data di arriving at a terminal 40 at the time of image pickup operation is supplied to a subtracter 48 and detection data Li read out of a memory through a switch 41 connected to the side of a terminal (b) is subtracted from the data di, so that the value (di-Li) is supplied to a multiplier 49. The multiplier 49 multiplies the (di-Li) by data (Hs-Ls)/(Hi-Li) (Ls and Ls: detection data of representative element) read out of a memory 27 and an adder 50 adds the detection data Ls of the representative element from the memory 42 and an optimum offset constant C stored in a memory 51 previously to the output of the multiplier 49, so that corrected data Di is outputted from a terminal 52.
Abstract:
PURPOSE:To release automatically loop-back at trouble by providing a communication equipment with a means which monitors the state of an annular data transmission line and gathering and accumulating information at intervals of a certain time and comparing information with a set value to judge restoration from trouble. CONSTITUTION:A common control part 22 of each of plural communication equipments connected by duplexed annular data transmission lines detects the state of each transmission line according as frame synchronization can be detected by a synchronization detecting part 19 or not. If a trouble is detected, by-pass switches 20A and 20B are controlled to set the loop back. A timer 24 is used to check states of transmission lines at intervals of a certain time, and results are counted. If the counted value does not exceed a preliminarily determined threshold after a certain time, restoration from the trouble is judged to instruct the release of loop-back.
Abstract:
PURPOSE: To lighten the load of a communication system of an annular transmission line for assembling in a node drifted away from the system, by setting prescribed assembling-in requesting information in a communication frame and repeating the information and, when the information is detected by a monitor device, causing the device to start the node assembling-in process. CONSTITUTION: A communication frame has an assembling-in requesting section 32 between a header section 30 and data section 31 and the section 32 is composed of a used bit section 33 and address section 34. Upon detecting the requesting section 32 from the count value of a slot counting section 9, a comparator section 8 informs a control section 10 of the detection and the control section 10 inspects the used bit section 33 and, when the used bit is '1', causes the communication frame to be repeated as it is. Upon receiving the communication frame, a monitor device starts assembling-in process for assembling the node of the address which is the content of the address section 34 in the communication system. At the node making the assembling-in request, the time slot number of its own node is set in the register 12 of the comparator section 8 from the control section 10 when the reception of a communication cable, etc., is completed by the assembling-in process, and a communicatable condition is set. Therefore, the load of the communication system of an annular transmission line for assembling in a node which is drifted away from the system is lightened. COPYRIGHT: (C)1986,JPO&Japio
Abstract:
PURPOSE: To use effectively a time slot by providing a count section renewing its value when a signal passes through a supervisory device into a frame circulating a ring data transmission line to assign the same time slot to a low-speed communication line in time division. CONSTITUTION: A counter part is provided to a frame header part of a frame flowing onto a ring data transmission line 5. Then every time a frame passes through, the highway supervisory device 1 renews the content of the counter part. Each communication device 2 compares the count value set to a line adaptor 3 with the content of the counter part and when both of them are coincident, a prescribed time slot in the frame is used.

Abstract:
PURPOSE:To prevent stations from receiving their own sent data by providing a communication mode part in each time slot, and turning off the communication mode part at each station when terminal information of an originating and a terminating station turns on and starting communication operation. CONSTITUTION:A data highway system is provided with a communication mode part CMM in each time slot TSl. When a communication circuit is set between the originating station and terminating station, a highway monitoring device SV turns on a communication mode assigned by a communication mode control part to send out data and then turns on terminal information parts SDR and RDR corresponding to their own stations when the date set ready is turned on. When the terminal information parts SDR and RDR of both stations are turned on, common control parts 5 of those stations turn off a communication mode part CMM to start a communication.
