Inventor: YAMAMOTO TAKASHI
IPC: A01N25/12
Filed: 1984-03-05
Abstract: PURPOSE:To provide a granular agent for controlling the mosquito larvae and algae in a reservior or water channel, by dispersing an active component in a waxy substance, and applying the dispersion to the water-soluble or water-dispersible core non-uniformly in a manner so as to fall off by the contact with water. CONSTITUTION:An active component is dispersed in a waxy substance (e.g. paraffin) to obtain a crust having a specific gravity of <=1. The dispersion is applied non-uniformly to a water-soluble core (e.g. urea, sucrose, etc.), a water-dispersibe core (e.g. obtained by mixing fine powder of clay, glass, etc. with the material of the above water-soluble core, optionally kneading with a binder to form granules of definite size, and granulating the mixture), or a core obtained by forming a water-soluble thin layer on a non-dispersible core (e.g. marble). The obtained granule sinks in water when thrown into water, however, water is permeated into the core through the gap of the non-uniformly applied waxy substance layer to separate the waxy substance from the core. The separated crust floats on the water surface and exhibits activity to control the noxious life.

Title: Data base controller
Inventor: MOCHIZUKI HIROKI
IPC: G06F12/00
Filed: 1990-02-21
Abstract: PURPOSE:To reduce the time manhour in production of an index by producing simultaneously plural indexes when an index part of a data base is produced. CONSTITUTION:An index production control part 2-3 receives sequentially the information obtained via a data base control part 2-1 and produces an index via an index evolving part 2-8. A work area allocating part 2-9 secures a work area 2-6 which is needed for simultaneous production of plural indexes. In this case, initial allocating part 2-10 first secures an area. Then a variance allocating part 2-11 changes the allocation of the area when the number of areas must be increased or decreased in response to the evolution processing. An index- based rearrangement part 2-12 allocates a work area 2-7 for rearrangement via an initial allocating part 2-13 and performs the rearrangement of indexes so as to secure the clear correspondence between the index items and the serial Nos and at the same time evolves these indexes. As a result, the time manhour can be reduced for production of indexes.

Abstract: PURPOSE:To obtain a voltage/current conversion circuit by cancelling an offset voltage with a current to a resistive element and the resistive element provide to a noninverting input of an operational amplifier circuit so as to cancel the offset voltage with high accuracy. CONSTITUTION:A DC voltage VB is applied to an output terminal Iout via a resistor Rmon. The resistance of the resistor Rmon is selected equal to a resistance of a resistor Roff. Even when an input voltage Vin and the DC voltage VB equal to each other are given to an operational amplifier circuit 1, an offset current Iout flows to the resistor Rmon to produce a voltage due to an input offset voltage of the operational amplifier circuit 1 or the dispersion in currents Ip, In. The input voltage Vin set equal to a reference voltage VREF, an output terminal voltage and the voltage VREF are compared with a comparator circuit 2, from which a 1-bit digital signal is outputted. The signal is given to a digital feedback circuit 3 to control a switch Soff so that two inputs to the circuit 2 are equal to each other. As a result, a generated offset signal is cancelled and a DC current Iout corresponding to the input DC voltage VREF is obtained.

Title: Lc type variable frequency filter
Inventor: IKEDA HIROSHI
IPC: H03H7/09
Filed: 1985-03-05
Abstract: PURPOSE:To attain use of the titled filter even with large power and to widen the variable range of a cut-off or passing frequency by using a magnetic substance resonator whose resonance frequency is changed by a magnetic field as a component. CONSTITUTION:An L and a C are formed by a ferrite sintered body 1A and electrodes 1B, 1C and in flowing a current I to an exciting coil 1D, a magnetic field H is generated. The magnetic field H is fed to the body 1A via the elec trode 1B and the specific permeability mus of the body 1A is changed depending on the strength of the magnetic field H. Thus, the resonance frequency of the magnetic substance resonator 1 is changed and the cut-off or passing frequency of the filter comprising a capacitor C1 and the resonator 1 is changed. The dielectric strength of the resonator 1 depends on the ferrite sintered body 1A and since the dielectric strength of the body 1A is larger than the reverse volt age of a varactor diode, the filter is used up to a high voltage, and the handled power is large and also the variable range of the resonance frequency of the resonator 1 is large. Thus,the variable range of the cut-off or communication frequency is widened.

Title: Method and apparatus for preparing synthetic resin pellet
Inventor: KASAMATSU TADASHI
IPC: B29B9/06
Filed: 1986-02-27
Abstract: PURPOSE:To easily carry out making pellets of a resin having low melt viscosity by cutting the resin extruded from a die and thereafter by bringing them into contact with flowing down water by means of gas flow to cool them and by separating the solid from the liquid. CONSTITUTION:A synthetic resin extruded from an extruder 1 is cut by means of a rotating knife 3 moving along the die surface and thereby becomes granular. Gas flow is blown to the synthetic resin granules by nozzles 4 and a gas supplying means and is then solidified by a cooling cylinder 5 on which cooling water 9 is flowing down. To recover the granules from the mixture of the cooling water and the cooled granules, the synthetic resin granules are separated by using a solid-liquid separating means. As it is possible to keep the die temp. high and to hold the flow resistance at the die low in this way, resin pellets can be easily prepared from a resin of low melt viscosity.

Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To minimize error correction probability by calculating a relation between a remainder obtained at the time of dividing a received polynomial by a generated polynomial at the time of decoding a received signal and an error, and calculating a relation between redundant data length and block length, and calculating the functions of a Galois field, redundant data length, and block length, and calculating their relation for setting the minimum error correction probability. SOLUTION: In this method for setting a Read-Solomon code, at the time of decoding received information in which an error is included in a transmitted polynomial, a relation between a remainder obtained at the time of dividing a received polynomial by a generated polynomial and an error is calculated, and an error correction probability p is calculated from the formula. The error correction probability p is calculated as the functions of a base [n] of a Galois field [GF(2n)], redundant data length [t], and block length [L] as shown in this formula. Thus, it is possible to decide the Read-Solomon code under the consideration of the proper error correction probability p by calculating the value of the base n of the Galois field.

Title: Noise-proof device for washing machine
Inventor: SUZUKI YASUYUKI
IPC: D06F37/26
Filed: 1989-02-22
Abstract: PURPOSE:To achieve a satisfactory noise-proof effect by means of a member substituted for a noise-proof member by performing simpler work, by furnishing a cylindrical noise-proofing member between a dewatering basket and a wash basin. CONSTITUTION:When a dewatering basket 11 containing laundry 14 is rotated, the water contained in the laundry 14 is splashed through holes of the dewatering basket 11 on to the wall of a noise-proof member 15 by the centrifugal force due to the rotation of the dewatering basket 14, however, the wall of a dewatering basin 10 is of a double wall construction, and the splash does not directly hit on to the dewatering basin 10 itself, so that the impact is prevented from transferring to a main body, resulting in an effective noise- proofing. And, as the noise-proof member 15 itself has a cylindrical shape, the water splashes in an uniform direction and the hitting angle becomes obtuse when the water hits on to the noise-proof member 15, so that the hitting noise itself is diminished.
