Title: Radiation detecting element
Inventor: MATSUMURA ATSUKI
IPC: H01L39/02
Filed: 1991-09-20
Abstract: PURPOSE:To reduce dispersion of signal magnitude by decreasing the ratio of electrons captured on a surface of a superconductor to the electrons being excited inside the superconductor by radiation, for a radiation detector using a superconducting tunnel junction. CONSTITUTION:Radiation is absorbed into a superconductor 12 or 14, and electrons are excited. The excited electrons diffuse and spread into each superconductor and can be picked as a signal by tunneling a tunnel barrier 13. To control the ratio of the excited electrons captured on a surface of the superconductor during diffusion of the excited electron into the superconductor, the superconductors 17 and 18 having an energy gap larger than that of each superconductor 12 and 14 are formed on the surface of the superconductors 12 and 14.

Title: Product coated with composite body and its production
Inventor: HOSOYA TOSHIFUMI
IPC: B32B7/04
Filed: 1985-12-02
Abstract: PURPOSE:To improve adhesiveness without generating gaps and change of inside diameter between layers and to provide stable coating performance by adding a compounding agent which migrates between an outside layer and inside layer to the coating layer on the outside layer of plural coating layers so that the rate of the migration from the outside layer to the inside layer is made equal to or larger than the rate of migration in an opposite direction. CONSTITUTION:The two coating layers (preferably the coating layers consisting of rubber or plastic) 2, 3 are formed on the outside of a wire 1. The resin layer 2 is a soft layer and the resin layer 3 is a hard layer. A plasticizer or migratable material such as silicone oil or uncured resin is preliminarily added to the layer 3 at the content higher than in the layer 2. The migratable material migrates from the layer 3 to the layer 2, thereby preventing the diametral expansion of the layer 3 which is the cause for the generation of gaps.

Abstract: PURPOSE:To improve the transmission efficiency of a data without giving unnatural sense to a recipient by comparing sent voice amplitude information with amplitude of a received signal and using a mode signal specifying kinds of transmission information so as to control the ratio of the voice information to the data. CONSTITUTION:A voice signal inputted from a telephone set 1 is inputted to a voice compressor 7 via a hybrid transformer 5.

When the sent amplitude is larger than the received amplitude, the mode signal transits to the mode '2'. When the mode '2' is consecutive for aprescribed period, the mode signal transits to the mode '1'.

Title: Measuring method of cluster of water
Inventor: SUGIOKA MIKIO
IPC: G01N21/31
Filed: 1992-09-11
Abstract: PURPOSE:To determine in a short time in an easy measurement whether the cluster of a sample water is large or small to that of a reference water by obtaining the differential spectrum of the reference water and the sample water, and comparing a differential spectrum multiplied an integral number of times of the differential spectrum. CONSTITUTION:In order to compare the clusters of a plurality of kinds of waters coming from different places or processed in different methods, data of the absorption spectrum in a predetermined wavelength range is obtained for every sample water by a spectrophotometer. The cluster of a general water is smaller than that of the distilled water, so that an absorption peak is shifted to the side of a shorter wavelength, resulting in a narrow peak width. Even when the absorption spectra of a plurality of samples are simply overlaid and shown in a graph to compare the samples, the difference of the spectra is so small that the spectra are nearly overlapped. Therefore, the comparison is difficult. For the purpose of detecting the difference of the spectra with high sensitivity, the differential spectrum of one sample water as a reference water and the other sample water is obtained, which is further multiplied an integral number of times. Then, the multiplied differential spectra are compared each other.
