Title: Highly sensitive search signal detecting radar system
Inventor: HIROZAWA HARUTAKA
IPC: G01S13/28
Filed: 1991-06-24
Abstract: PURPOSE:To lengthen the maximum detectable distance, and improve S/N by restricting a reception signal band by means of a filter by which center frequency is changed in the front stage of a pulse compressor according to frequency deviation of a transmission pulse signal. CONSTITUTION:Preset voltage corresponding to center frequency being inputted to a voltage adder 19 for initial acquisition is set by manual operation, and a dynamic tracking filter DTF 16 is set in passage band width having prescribed center frequency. Here, when a reception IF signal is transmitted from an IF amplifier, it passes through the DTF 16, and a level detector 17 detects a significant level, and outputs a set pulse. When a sawtooth wave generator 18 receives the set pulse, it generates a sawtooth wave having a prescribed inclination, and changes the center frequency of the DTF 16 in an inclination (frequency deviation quantity/pulse width of long pulse), and sends wave filtered output based on this center frequency to a pulse compressor. Here, since a pulse uncompressed signal is a linear frequency modulated signal, the band width of the DTF 16 can be set sufficiently narrowly, so that S/N can be improved.

Abstract: PURPOSE:A three-layered structure consisting of two enzyme-immobilized membranes and the material for flowing the substrate solution, and the material for flowing the reaction product solution are rolled around the porous hollow tube to provide a spiral membrane type enzyme reactor with high enzymatic reaction efficiency per unit area. CONSTITUTION:The enzyme-immobilized membrane 31 is folded into two sheets so that the material for flowing the substrate solution 32 is put between them to form a three-layered structure 3. The resultant three-layered structure 3 and the material for flowing the reaction product solution 4 are rolled around the porous hollow tube 2 so that the material for flowing the reaction product 4 comes outermost. Then, the material 4 and the membranes 31 are sealed water- tightly at both ends of the roll as well as at the sheet end of the roll 10. Thus the resultant roll has openings only between the membranes 31 and 31 at the both ends. When the substrate solution 5 is fed from the opening in the axis direction the roll, the solution flows along the material for the substrate solution, while the substrate reacts with the enzyme and the product is taken out of the hollow tube 2.

Filed: 1994-07-05
Abstract: PURPOSE:To obtain a fishing line made of polyester having change in thickness in the length direction while maintaining characteristic properties of the polyester such as low water vapor absorption, high modulus of elasticity and high transparency, comprising thick parts and fine parts in fineness in the length direction and at least in the fine parts of which hydrolysis traces exist. CONSTITUTION:Plural polyester fiber monofilaments are bundled and parts to be thinned are immersed in an aqueous solution of an alkali such as sodium hydroxide and subjected to alkali weight reducing treatment. A fishing line 1 has thick parts 2 and thin parts 3 and hydrolysis traces (erosion traces) or fine pores (recessed parts) 5 exist on the surface of the parts subjected to alkali weight reducing treatment. Since the fishing line 1 has fine unevenness on the surface and causes irregular reflection by the hydrolysis traces (erosion traces) 4 and the fine pores (recessed parts) 5, it has no glittering luster. Parts to be knotted do not require alkali weight reducing treatment and retain high knot strength.
