Title: Semiconductor integrated circuit
Inventor: YAMAGUCHI ATSUO
IPC: H04B10/556
Filed: 1985-08-05
Abstract: PURPOSE:To improve a frequency characteristic by using inversional amplifiers using no pnp transistor (TR) to constitute an amplifier circuit and a peak holding circuit, inputting an amplified output and a peak holding output to two respective inputs of a voltage comparator and outputting a binarization output. CONSTITUTION:An output of a photodetecting element 1 is inversionally amplified by the 1st amplifier 17, branched and then inputted to inversional amplifiers 18, 19. The inversional amplifier 19 constitutes a peak holding circuit together with a diode 13 and a capacitor 14. In this case, pnp TRs having low frequency characteristics are not used for these inversional amplifiers 17-19. Since respective amplifiers 17-19 are formed on the same semiconductor integrated circuit, the dispersion of DC characteristics is suppressed. When the amplification degree of the peak holding inversional amplifier 19 is set up to a half of that of the amplifier 18, the reference voltage of the voltage comparator goes to a half of the peak.

Title: Radioactive material sampling device
Inventor: SAKAMOTO YUKINORI
IPC: G01T1/167
Filed: 1988-07-12
Abstract: PURPOSE:To prevent the quantity of radioactivity from exceeding a permissible quantity and to performing safe nuclide analysis radiation measurement for a sampled radioactive material by closing a supply valve when the integrated quantity of radioactivity exceeds the permissible quantity. CONSTITUTION:A 1st computing element 21 calculates the radioactive concentration of the radioactive material collected by a filter 5 from the component ratio and the radioactive concentration of rare gas. Then a 2nd computing element 23 also calculates the quantity of radioactivity of the collected radioactive material from a sampling quantity per unit time and its radioactive concentration. Further, a 3rd computing element 24 uses collection efficiency to calculate the real quantity of radioactivity. Then an integrating computing element 26 integrates the actual quantity of radioactivity per unit time and when the integrated quantity of radioactivity exceeds the permissible quantity, a comparing computing element 27 sends a closure command to the supply valve 4 to close the valve automatically. Therefore, the quantity of radioactivity of the radioactive material such as dust and iodine collected by the filter 5 never exceeds the permissible quantity.

Title: Optical function element
Inventor: KANAMORI TERUHISA
IPC: G02F1/01
Filed: 1982-10-04
Abstract: PURPOSE:To apply an optical function element as an optical switch, an optical modulator, or the like, by using a threshold switch material applying the interaction between the light accompanied with its electric threshold switch phenomenon and the material optically. CONSTITUTION:When A=A0 is made true with respect to an intensity A of the exit light in the case, where an incident light 4 is made incident from one end of a fiber 1 and is emitted from the other end, and a voltage Von is applied across electrodes 2 and 3 and a threshold voltage pulse Vth is applied, A=A0-DELTAA is true. The reason is that an on-state filament is formed between electrodes 2 and 3 and the light is scattered because of the difference of a refractive index difference from the off state. When the voltage Von is increased to increase a current Ion in this state, the sectional area of the on-state filament is increased in proportion to the current Ion, and the intensity A of the emitted light is lowered furthermore, and therefore, this device can be applied as an optical attenuator which can be controlled by a voltage.

Title: Liquid phase composition adjusting method in liquid phase epitaxial growth
Inventor: SHIMURA MIKIHIKO
IPC: H01S5/00
Filed: 1981-10-28
Abstract: PURPOSE:To drastically curtail a time required for weighing by severely weighing only materials except for GaP in case of obtaining an In-Ga-As-P solution with In used as the solvent. CONSTITUTION:For obtaining an In-Ga-As-P solution with In used as the solvent which is used for liquid phase epitaxial growth of the mixed In1-xGaxAs1-xP2 (0<=x<1.0<=z<1) on a semiconductor substrate GaAs1-yPy (0<=y<1), severe weighing is carried out only for materials except for GaP having the highest melting point. Amount of GaP to be added exceeds the solubility thereof at a growth temperature or saturation temperature of solution. Thereby, the solubility of GaP is inevitably determined by the solubilities of other materials. As a result, a liquid phase composition can be easily adjusted within a short period of time.

Title: Production of high-quality hollow steel ingot
Inventor: SAITO KENJI
IPC: B22D7/04
Filed: 1984-08-23
Abstract: PURPOSE:To prevent inverse V segregation on the inside peripheral surface of a product and to obtain a hollow steel ingot having high quality by installing a metallic cylinder having the same axial center as the axial center of a core into an annular casting space and casting the ingot. CONSTITUTION:A casting mold 2 is set on a molding board 1 and the core 3 of the concentrical double steel pipe 3a, 3b construction is set in the central part in the mold. Refractories 4 are then packed between the double pipes 3a and 3b and air is passed through the inside of the core 3 from a cooling air supply pipe 5 in order to suppress the temp. elevation of the core 3. The metallic cylinder 6 is then installed into the casting space between the core 3 and the mold 2 and a molten steel is poured into the space. Then the solidification is accelerated in the part in contact with the cylinder 6 as the temp. decrease of the molten steel in said part is considerable. The growth of the solidified shell on the inside surface side of the hollow steel ingot is thus accelerated. The reason for increasing the solidifying speed on the inside peripheral surface of the hollow steel ingot lies in that the inverse V segregation is decreased and that the generation region of the inverse V segregation is narrowed to the limited region in the steel ingot.
