IPC: G02F1/035
Filed: 1983-06-29
Abstract: PURPOSE:To simplify processes and eliminate a leak of guided light to an electrode part by setting the angle between the waveguide direction of an optical waveguide having an electrode on a surface and a connecting electrode for a connection with an external circuit to <=90 deg.. CONSTITUTION:Electrodes 21 and 22 on ridge type optical wave guides 11 and 12 and connecting electrodes 41 and 42 are manufactured in the same process on the same plane, and the angle theta between the optical waveguide 12 and connecting electrode 41 is set to <=90 deg.. In this constitution, when light is made incident to the optical waveguide 12 from an incidence terminal 51, a part of the light is propagated normally to a branching optical waveguide 50 at a halfway point, but the angle 0 is set to <=90 deg., so only an optical wave of a component in the direction opposite to the incidence direction is allowed to propagate to a branching optical waveguide 50, so that there is not any loss originating from a leak to the branching optical waveguide 50.

Title: Permeating quantity measuring instrument for thermopervaporation device
Inventor: OKAWA YUJI
IPC: G01N15/08
Filed: 1986-05-20
Abstract: PURPOSE:To measure the permeating quantity of vapor with high accuracy by supplying original liquid to one side of a hydrophobic porous film, liquefying vapor of the original liquid permeating through the film, and detecting the difference in flow rate between the entrance and exit of its cooling liquid passage. CONSTITUTION:In a thermopervaporation module 1, the module is partitioned by a hydrophobic porous film 102 having the selective permeation, that is, the vapor of liquid is made to permeate, but the liquid itself cannot permeate, so as to form an original liquid passage 101 and a cooling liquid passage. The original liquid is heated by a heat tank 3 and sent by a pump to the original passage 101, where only vapor permeates into the porous film 102 and liquid is returned to a tank 3. Further, the vapor having permeated into the porous film 102 is liquefied in the cooling liquid passage 103, put in a cooling tank 2, and sent by a pump 6 to the cooling passage 103. At this time, a flow meter 9 is provided on the entrance side of the cooling liquid passage 103 and a flow meter 15 is provided on the exit side, thereby computing the permeating quantity of the vapor from the difference between the exit flow rate and entrance flow rate. The flow rate difference across the cooling liquid passage is therefore found, so the permeating quantity of the vapor is measured easily and accurately.

Title: Detection of descending behavior and heaped structure of charge in blast furnace
Inventor: ITAYA HIROSHI
IPC: C21B7/24
Filed: 1982-07-05
Abstract: PURPOSE:To perform titled detection at the optional height level in a blast furnace without exerting the influence of the flowing-in of the charge near the furnace top and redistribution on the detection, by determining the fluctuation of the changing speed of pressure between the measuring points at the plural positions apart a distance almost speed to the thickness of a single kind of the charge in the heaped layer in the furnace. CONSTITUTION:The pressure gradient in the layer thickness direction of the charge in a furnace heaped alternately by the fractional charge of ores and coke depends largely on grain sizes and void volume if the flow rate of gas is specified, and if the grain sizes and void volume increase, the pressure gradient decrease. Since the average grain size and void volume of the coke are larger than those of the ores, the pressure gradient changes periodically at the pressure measuring point, and the time when the boundary position of both layers passes the measuring point can be exactly detected from the speed of abrupt change in pressure. If the pressure change is measured with measuring devices 14 on upper and lower sides apart by DELTAL in the height direction, 10, 11 in the figure are obtained, and in the latter, the pressure change delays by a certain time DELTAt. Since DELTAt is the time required for the descend DELTAL of the charge, the descending speed of the charge is v=DELTAL/DELTAt.

Abstract: PURPOSE:To securely inspect a weld zone, etc., from a position nearby the internal surface of a tube cavity, etc., by notching the external peripheral surface of the tip part of a part where an observation optical system is stored slantingly to the axial direction. CONSTITUTION:A figure shows that the insertion part of an endoscope is inserted into the combustion chamber container in a jet engine and the weld zone 103 of a liner 102 is inspected by using the optical system in the presence of lighting by an illumination optical system arranged in the tip part 6.
