IPC: G09G5/00
Filed: 1984-04-20
Abstract: PURPOSE:To shorten the time required for a retrieval by providing write side and read-out side memories which are operated independently, on a code memory, decoding and displaying an approximate picture of a detailed picture at a high speed, and deciding by the approximate picture whether the relieval is correct or erroneous. CONSTITUTION:A code memory 22 of an encoding device 15 is provided with a write side memory 22-2 and a read-out side memory 22-1 which are operated independently. In case of decoding, first of all, when a code of the third layer being a basic code is inputted successively to an operating part 21, it is stored in a frame buffer 24 through the memory 22-2. Subsequently, a display device 16 reads out the contents of the buffer 24, a picture of the third layer is displayed, and when a partial area is indicated through an indicating device 17, the next decoding is executed. In this state, the read-out side and the write side of the memory 22 are shifted, said picture is inputted to the operating part 21 successively together with differential information from the center, and synthesized, and an approximate picture of a detailed picture is decoded and displayed at a high speed. By deciding by this approximate picture whether the retrieval is correct of erroneous, the time required for the retrieval can be shortened.

Title: Thermosettiing resin composition
Inventor: HOSOGANE TADAYUKI
IPC: C08G69/48
Filed: 1990-03-28
Abstract: PURPOSE:To obtain a thermosetting resin composition having excellent processability and heat resistance by mixing a specified aliphatic unsaturated group-terminated aromatic polyamide oligomer with a maleimide derivative. CONSTITUTION:A resin composition prepared by mixing an aliphatic unsaturated group-terminated aromatic polyamide oligomer of the formula [wherein R1 and R2 are each a bivalent aromatic group; R3 is a bivalent aliphatic or aromatic group; A and B are each an aliphatic unsaturated group (A may be the same as B); and n is 0-15] with a maleimide derivative. The mixing ratio of the oligomer to the maleimide derivative is generally such that 10-200 pts.wt. maleimide derivative is present per 100 pts.wt. oligomer. When the amount of the maleimide added is below 10 pts.wt., the heat resistance is good but the moldability improving effect is small because of a small melting point drop. When this amount is above 200 pts.wt., the melting point is substantially the same, and not only any further melting point drop cannot be recognized but also the heat resistance of the molding is decreased and besides the polymerization reaction is so violent that is can difficultly be controlled.

Filed: 1989-03-30
Abstract: PURPOSE:To attain low distortion and a low noise by using a specific field effect transistor in a semiconductor device comprising an amplifier, and suppressing a 2nd-order distortion component in output. CONSTITUTION:In characteristic of gm (mutual conductance) to VGS (voltage between gate and source), a FET in which the gm is provided with a flat area centering an operating bias VGS=0V is used. The value of DELTAgm is suppressed less than 8mS within a range of VGS=+ or -0.15V, and the value at VGS=0V is suppressed at the value less than 20% of the value gm0=70mS. Such FET can be obtained by comprising the carrier density profile of an active layer 1 in thickness direction so as to decrease carrier density less than on-going one in the neighborhood of the surface of a Schottky gate electrode 2, and to increase the density at a deeper part higher than the on-going one. Thereby, the low distortion and the low noise can be attained.

IPC: H01S5/00
Filed: 1983-05-09
Abstract: PURPOSE:To obtain a distributing reflection type single axis mode semiconductor laser having characteristics of high performance by forming a distributing reflecting mirror having high diffraction efficiency by forming the periodic variation of a refractive index at approximately central section of a waveguide. CONSTITUTION:An active layer 5 is connected to an optical waveguide layer 2 in a distributing reflecting mirror in a butted shape against each other. The layer 5 is held by semiconductor layers 1 and 3, forbidden band width thereof is larger than that of the layer 5 and a refractive index thereof is smaller than that of the layer 5, and an end surface 60 on the right side is formed in a reflection plane. When the layer 1 takes an N type and the layer 3 a P type, injected carriers are confined efficiently in the layer 5 and emit light because double hetero-structure in which a P-N junction is shaped at the layer 5 is formed. Emitted rays advance to the left side in the layer 5, and project to the layer 2 through the node 50. Rays corresponding to a black wavelength among them are diffracted intensely and return to the layer 5. Accordingly, the distributing reflecting mirror forms a wavelength selective resonator together with a reflecting mirror of the end surface 60 of the layer 5. The structure has characteristics in which the coupling factor of rays can be taken in a large value, an oscillating threshold is low and differential quantum efficiency is large.

Title: Apparatus for measuring concentration ri in blood
Inventor: YAMAMOTO SEIICHI
IPC: G01T1/172
Filed: 1990-03-27
Abstract: PURPOSE:To enhance sensitivity and to reduce background counting by coincidence counting beta-rays and annihilation gamma-rays by two or more detectors using scintillators easily permitting beta-rays to transmit and having high density. CONSTITUTION:The beta-rays from a tube 10 through which blood passes are absorbed by a plastic scintillator 12a to be converted to light which is, in turn, measured by the PMT (photosensor) 12b of a side surface. Annihilation gamma-rays emit fluorescence by the opposed scintillator 14b provided on the outside to be measured. The signals of the scintillator 12a and the opposed scintillator 14a are coincidence counted by a coincidence counting circuit 22 through respective PMTs 12b, 14b. By this method, even when the threshold of beta-rays is set low, the coinicidence counting with gamma-rays is performed to make the effect of a background hard to receive and, in the same way, the background counting due to the coincidence counting of scattering gamma-rays can be also removed. By this method, the measuring sensitivity of radioactivity is enhanced and background counting is reduced and the shielding of lead can be reduced and miniaturization and wt. reduction can be achieved.
