Title: Method for evaluating creep damage to heat-transfer tube
Inventor: NAKADAI MASASHI
IPC: G01N3/00
Filed: 1993-05-18
Abstract: PURPOSE:To evaluate creep damage to a heat-transfer tube with the operating condition of the tube as well as environmental changes taken into account and also to evaluate the extra life of the heat-transfer tube by integrating a creep damage ratio per unit operating time calculated from the stress and creep rupture curve of the heat-transfer tube both of which depend on the amount of reduction in the wall thickness of the tube or the like. CONSTITUTION:Temperature rises of a heat-transfer tube for use in a high-temperature, high- pressure environment, which are caused by generation of an oxide scale on the outer surface of the heat-transfer tube and a steam scale on the inner surface of the tube, are simulatively calculated. With the amount of reduction in the wall thickness of the tube per unit operating time and change in the thickness of each scale taken into account, the stress on the heat- transfer tube is calculated from the relationship between the amount of reduction in wall thickness, caused by precalculated creep damage and by generation of the high-temperature oxide scale and the thicknesses of the generated steam and oxide scales, while using the operating temperature, pressure, and heat collection rate of the heat-transfer tube to be evaluated, the thermal conductivity of the scales, and the outside diameter and wall thickness of the heat-transfer tube, etc. A creep rupture time for the temperature and the stress computed is obtained from a creep rupture curve from which the precalculated effects of oxidation are eliminated, so as to obtain a creep damage ratio. The above operations are repeated to calculate the time required for the tube to reach the end of its life due to creep at which integration of the creep damage ratio is 1, so as to evaluate the extra life of the tube.

Title: Car display
Inventor: ISHIKAWA TOMOHISA
IPC: B60Q1/34
Filed: 1992-05-29
Abstract: PURPOSE:To make any useless light for a succeeding car so as not to be diffracted by an extraneous light by sticking a protective film, coated with an antireflecting layer, fast to the surface of a hologram sheet installed at the inside of a single plate pane of glass. CONSTITUTION:A hologram sheet 1 is installed at the inside of a single plate pane 4, and a protective film coated with an antireflecting layer 2 is stuck fast to a surface of this hologram sheet 1. With this constitution, any possible reflection of an extraneous light at an interface with air is kept back, while such a fear that an amount of reincidence of reflected light gets into the hologram sheet 1 is held down to the utmost, and the extent of diffraction to the rear such as a succeeding car or the like is reduced, insomuch that there is no hindrance from the practical standpoint. In addition, since any reflection of a light out of a regenerative light source at the surface of an uppermost part of the inside pane is reduced and it is efficiently made to be incident into the hologram sheet 1, a utilization factor of irradiated light from the regenerative light source is well improved, and thus display is yet more lightened in this way.

Title: Detecting method of faulty or stained insulator
Inventor: INOUE TORU
IPC: G01R31/12
Filed: 1991-06-11
Abstract: PURPOSE:To discriminate a faulty or stained insulator by making evaluation by using a value which is obtained by dividing a difference between the maximum and the average value of measured values in a specific frequency band of a radio wave radiated from aerial transmission equipment, by a fundamental wave height at the time of occurrence of an extraordinary wave. CONSTITUTION:Measured radio wave data subjected to distance correction by a distance correction circuit 30 are supplied to a fast Fourier transform circuit 34 and a sudden wave detecting circuit 36 through a buffer memory 32. The circuit 34 divides the measured wave data into frequency channels CH1 to 22 and outputs them, while the circuit 36 outputs signals showing the position of occurrence, the crest value, the continuation width and the number of occurrences in a processing section of a sudden wave detected, respectively. These measured data are recorded, together with other necessary data, in a bulk data recording device 49. Measured values are subjected to an arithmetic processing by an evaluation value calculating circuit 102 and a value obtained by dividing a difference between the maximum value and the average value of the measured values by a fundbmental wave height at the time of occurrence of the sudden wave, that is, an evaluation value, is outputted. When the evaluation value exceeds a prescribed value, it is determined that a faulty or stained insulator is present.

Abstract: PURPOSE: To stabilize an operation of IC using a floating substrate by adjusting so as to have the maximum thickness xd max  of a depletion layer when a semiconductor layer in thickness t is equipotential to a source larger than t.  
     CONSTITUTION: An Si n-epitaxial layer is provided on an insulating substrate 1, a p-layer 2 is obtained through patterning, and a gate terminal 4 is provided by way of an insulating film 3. According to this constitution, a change in threshold voltage Vth is retained up until an electron injected in the layer 2 is extinguished; then from operating FET, a different operation is taken and a response changes in the previous pulse condition. A stable operation is not obtainable consequently. Now, a film thickness t of the layer 2 is selected smaller than the maximum value xd max  of a depletion layer when the layer 2 is equipotential to a source 5. From adding then voltage + Vg to the gate, xd max  is further turned incremental, however, an occurrence of the depletion layer is confined within the thickness t of the layer 2, which becomes constant at maximum value t and makes no change any more thereafter. Thus, MOSFET unchanging in threshold voltage and stable in characteristic is obtainable through adjusting impurity density and thickness t of the layer 2.
