Title: Method for detecting internal state of heat exchanger
Inventor: YOTSUTSUJI YOSHITOSHI
IPC: G01B15/00
Filed: 1985-12-20
Abstract: PURPOSE:To make it possible to detect the internal state of a heat exchanger without stopping the operation of the heat exchanger, by providing a dose source and a sensor etc. CONSTITUTION:Drive apparatuses 20 are provided at the lateral position of a heat exchanger to be inspected. At this time, the mount jigs 25 of the apparatuses 20 are moved to the uppermost or lowermost parts of main bodies 24 and made movable downwardly or upwardly from this state in synchronous relation to each other by the operation of a motor controller 26. In this state, collimators 29 and sensors 23 are mounted to the mount jigs 25 and the power sources of the apparatuses 20 are closed to adjust the heights of the collimators 29 and the sensors 23 so as to bring both of them to the same height. Next, the switch of each apparatus is closed and a dose source 22 is fed out to the position of the collimator 29 by a controller 28 and a recorder 40 and each apparatus 20 are further operated to enter measurement. In this measurement, the quantity of transmitted radioactive rays emitted from the dose source 22 and passed through the heat exchanger to be inspected and detected by the sensor 23 is reduced by a heat exchange tube to be inspected. Because the gaseous phase quantity of a gaseous phase part is large, an internal state can be estimated.

Title: Logic simulating system
Inventor: IWAWAKI KUNIO
IPC: G06F11/25
Filed: 1990-10-29
Abstract: PURPOSE:To reduce the number of times of the evaluation of an expression, and to speed up logic simulation by giving a function to keep the propagation of an event waiting. CONSTITUTION:A logic simulator 11 executes the logic simulation of an existing function level and an existing gate level. When the event is generated, an event counter 12 provided for every signal name increases a count value only when the event corresponds to its signal. When the value of the event counter 12 becomes over some definite value, an event propagation stop function module 13 stops the propagation until another event comes to an end, and it suppresses the generation to the event more than necessitated in this way. Thus, the logic simulation can be speeded up.

IPC: H01L33/14
Filed: 1986-12-02
Abstract: PURPOSE:To improve the coupling efficiency with a fiber by providing optical guide layers utilizing a refractive index difference so as to interpose an active layer therebetween. CONSTITUTION:An element is formed of an InP, optical guide layers 2, 4 are formed of P-type In1-xGaxAsyP1-y, the composition of an active layer 3 is:x=0.24, y=0.55 or x=0.33 and y=0.79, and its band gap energy Eg is 0.95eV or 0.80V. Accordingly, the compositions of the layers 2, 4 are such that their band gap energy Eg satisfies 0.95eV<Eg<1.35eV or 0.80eV<Eg<1.35eV. The light emitted by recombination of carriers in an active region 9 is reflected at a boundary surface between the substrate 1 and a carrier confinement layer 5 since the layers 2, 4 are disposed at both sides of the layer 3, and propagated in an emitting end direction. Since this phenomenon occurs at both sides of the layer 3, light is condensed to the end of the region 9. Thus, the light can be radiated concentrically to the end face of the active region at the emitting end.

Abstract: PURPOSE:To diminish pressure difference between a driving face and a suction surface so as to reduce any leaking flow by rapidly diminishing a deflection angle from the vicinity of a tip to the tip itself in each blade which is attached to the periphery of a hub by leaving a little clearance between a casing and blades. CONSTITUTION:An axial flow compressor to be arranged inside a gas-turbine engine, etc., is such that a plurality of blades 3 are fixed to the periphery of a hub 1 to rotate centering around an axis for an engine by leaving a little clearance A between a casing 2 and blades. In this case, a deflection angle C for each blade 3 is rapidly diminished from the vicinity of a tip e.g. a position at approximately 90% from the blade root to the tip itself. While, for example, deflection angle C a flat plate having zero, exists on the tip and also an incidence angle A and a stagger angle B are made equal to each other. Pressure ratio of a driving face M1 to a suction surface M2 is increased to the vicinity of the tip, and rapidly diminished at the tip. Therefore, leaking flow due to pressure difference is reduced.
