Abstract: PURPOSE:To quickly capture polluted fluid in a wide area at high efficiency by installing a polluted fluid capturing hood in the center of an apparatus and an outer circumferential whirling flow generating part in the outer circumference of the hood and making the suction amount of the capturing hood larger than the amount to be blown to the outer circumference. CONSTITUTION:One or more whirling flow guiding plates 6 have the center part which is made to form an enclosing circle and a capturing hood 1 in which an impeller 2 of a centrifugal pump is built is so arranged as to set the suction inlet 3 upward and further a circular duct-like outer circumferential whirling flow generating part 9 is set in the outer circumference of the hood concentrically. A slit-like circular blowing outlet 4 is opened in the inner circumference of the upper end part of the whirling flow generating part 9 while being set to face the outer circumference of the guiding plate 6, and a dust 8 extended in the rotary direction of the impeller 2, which is the tangential direction of the side wall, is installed in the side face of the capturing hood 1 and communicated with the outer circumferential whirling flow generating part 9. The suction amount of the suction inlet 3 is made to be larger than the spiralling and blowing amount from the outer circumference of the apparatus. In this way, the spiralling whirling flow can be accelerated and the force to move upward of the fluid is increased and the capturing work is heightened.

Title: Capillary column
Inventor: SOGA NAOHIRO
IPC: G01N30/10
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce the amount of mobile phase consumption, reduce a load pressure, and achieve high-speed separation by forming a silica gel in double- pore structure where a silica skeleton with a pore with each specific size in a capillary whose inner diameter is equal to or less than a specific value is interwined. SOLUTION: A compound that is thermally decomposed is dissolved in a reaction solution in advance, a gel consisting of a solvent-rich phase and a skeleton phase that is rich in silica and has a pore on the surface is adjusted in a capillary, and the gel in wet state is heated, thus thermally decomposing the compound and drying the gel. As a result, in a column, a silica gel in double pore structure where a silica skeleton with a pore (through pore) with 0.5-5 μm size and a pore (meso pore) with 2-50 nm size in a capillary whose inner diameter is 1,000 μm or less is interwined is formed. In this case, when the diameter of a through pore is smaller than 0.5 μm, a load pressure becomes larger. On the other hand, when the diameter is larger than 5 μm, a separation performance becomes inferior. Also, when the diameter of the meso pore is smaller than 2 nm, solvent dispersion becomes difficult. On the other hand, when it is larger than 50 nm, separation becomes insufficient.

Abstract: PURPOSE:To change a parallel/serial conversion format every data communication and to prevent communication data from being stolen or a memory card from data leakage or alteration by sending data for fixing the parallel/serial conversion format to the memory card in every data communication of an external apparatus with the memory card. CONSTITUTION:At the data communication with the external apparatus 9, the memory card 7 receives the number of three digits using random numbers. When the number is ''622'' for instance, the transmission side replaces the bit D6 of data 10 by the bit D2 by the upper two digits of ''622'' to convert the data 10 into data ''a11'', the data ''a11'' are shifted to the right direction twice by the lower one digit of ''622'' to convert the data ''a11'' into data ''b12'' and transmit the bits D6-D1 serially and successvively. On the other hand, the receiving side receives the bits D6-D1 successively and serially to convert the obtained bits into parallel data ''b12'', shifts the data ''b12'' to the left direction twice to convert the data ''b12'' into data ''a11'' and replaces the bit D6 by the bit D2 to obtain the data 10 as normalized data. If data are to be transmitted/ received again after the end of transmission/reception, the data are received by the memory card 7, so that it is difficult to find out the serial/parallel conversion format and the memory card can be prevented from illegal use.

Title: Thin film optical waveguide and its production
Inventor: MATSUBARA SHOGO
IPC: G02B6/12
Filed: 1986-04-17
Abstract: PURPOSE:To resolve the anxiety about mixture of impurities and to shorten the work time considerably by forming an insulator film on a silicon single crystal substrate and forming an optical waveguide area consisting of an epitaxial crystal film or a perovskite type oxide and an area consisting of an amorphous film on said insulator film. CONSTITUTION:An amorphous film which should be the perovskite type oxide by heat treatment is formed on the substrate consisting of an insulator epitaxial film and a silicon single crystal and is irradiated with a laser beam. The irradiated part is heated by absorbing the light and is made crystalline to become an epitaxial film reflecting the crystallizability of the insulator film of the substrate. Since the crystalline part and the amorphous part are different in refractive index from each other, an optical waveguide is formed. Since the film is made crystalline by the laser beam, the beam diameter of the laser beam is controlled to the precision of the shape of the waveguide, and the irradiation time required for this treatment is very short to not only improve the precision of waveform formation but also simplify the process in comparison with plasma etching.

Abstract: PURPOSE:To make possible the considerable reduction in the sensitivity change and gradation change of a sensitometric curve with lapse of color developing time by using silver halide particles of a specific normal crystal as silver halide and combining the same with a pyrazoloazole coupler. CONSTITUTION:This material contains the pyrazoloazole coupler and the silver halide particles which are expressed by the formula and consist of the normal crystal having <=5% twin content. The fluctuation coefft. of the particle size of the silver halide particles is made preferably <=25%, more preferably <=20%. The fluctuation coefft. in excess of 25% is undesriable as the sensitivity change and gradation change of the sensimetric curve increase with lapse of the color developing time.

The average particle size (d) is more particularly preferably in a 0.3-0.6mum range.
