Title: Magnetic fluid and preparation thereof
Inventor: SASAKI MAKOTO
IPC: C10M133/02
Filed: 1991-04-12
Abstract: PURPOSE:To provide a magnetic fluid improved in long-term stability by incorporating specific ferromagnetic particles in a specific high-boiling organic solvent. CONSTITUTION:Ferromagnetic particles with a size of 3-500nm are treated with a polyisocyanate/alcohol reaction product of formula I (wherein R<1> is a 4-30C aliphatic hydrocarbon group or 6-30C alicyclic or aromatic hydrocarbon group of a valency of m+n; R<2> is a l-30 C aliphatic hydrocarbon group or 6-30C alicyclic or aromatic hydrocarbon group; m and n are each 1-3; and m+n is 2-4) or with a polyisocyanate of formula II and an alcohol of formula III to obtain ferromagnetic particles with an m-valent group of formula IV chemically bonded onto the surface. The ferromagnetic particles thus obtained are dispersed in 5-200wt.% high-boiling organic solvent with a boiling point of 150-600 deg.C under atmospheric pressure and a viscosity of 1-500cSt at 40 deg.C.

Title: Gas regenerating circulator for co2 laser
Inventor: HOTSUTA KAZUAKI
IPC: H01S3/097
Filed: 1980-08-01
Abstract: PURPOSE:To make it possible to obtain a large laser output having no lowering and no fluctuation, by installing a gas-blowing fan and a gas-heating heater on the upstream side of a ctalyst. CONSTITUTION:A regeneration circulator 6 is provided with a laser gas-blowing fan 7 and a gas-heating heater 8 on the upstream side of a catalyst tube 9 wound with a forced heat insulation heater 10. Thereby, because a laser gas is introduced to the heater 8 at a flow velocity determined according to the fan 7, the gas is heated efficiently. In addition, because the gas heated to a high temperature is blown against the catalyst tube 9, the catalyst therein acts highly excellently. Moreover, the flow rate fluctuation due to the heater heating temperature ripple hardly occurs and in addition, the gas flow rate increases. Accordingly, it is possible to obtain a large output having less fluctuation and no lowering.

Title: Wiretap preventing system for facsimile communication
Inventor: SAKAYAMA TAKASHI
IPC: H04N1/44
Filed: 1990-04-23
Abstract: PURPOSE:To prevent wiretap of facsimile communication by converting primary transmitted and received cipher parameters to secondary cipher parameters by using a predeterminate calculation formula and collating them with a cipher table to determine the ciphering system. CONSTITUTION:A primary cipher parameter generating part 13 performs the operation to convert random numbers Rn outputted from a random number generating means 12 to cipher parameters, and a secondary cipher parameter generating part 14 generates a secondary cipher parameter P based on a primary cipher parameter Pt generated in a local station and a primary cipher parameter Pr which is generated in a reception station and is added to a protocol control signal NSF and is transmitted. The conversion system corresponding to the secondary cipher parameter P is selected from the cipher table in a storage part 15, and the selected conversion system is indicated to an encoding/decoding part 3a. Thus, wiretap is impossible.

Title: Underwater receiver
Inventor: SUGIMORI HIDEKI
IPC: H04R1/44
Filed: 1990-04-25
Abstract: PURPOSE:To obtain a receiver having an excellent noise reduction performance without making a receiving element large in size, by a method wherein air being different in acoustic impedance from water is filled up inside a cylindrical shell which is a frame for arranging receiving elements. CONSTITUTION:The opposite ends of a cylindrical shell 1 are sealed hermetically with rigid disks 2 and an air chamber 3 is filled up with air. Receiving elements 7 are filled on the outer wall in the central part of the cylindrical shell 1. While a signal acoustic wave and back noise are received by the receiving elements 7 when they come, the ones that are not received do not enter the air chamber 3 of the cylindrical shell 1 but are diffracted or scattered from the surface, since the air being different in acoustic impedance from water is filled up in the air chamber 3 inside the cylindrical shell 1. Accordingly, reduction of the back noise can be attained without using a large-sized receiving element having directivity. Although the cylindrical shell 1 vibrates due to the diffraction or scattering on the surface of the cylindrical shell 1 and generates vibration noise in the medium, ribs 4 provided on the inner wall of the cylindrical shell 1 act to reduce this noise within the range of working frequencies, and thereby the effect of this vibration noise is also prevented.

Abstract: PROBLEM TO BE SOLVED: To enable the handling even in a bright room and ensure the good suitability to a direct image drawing process using a laser and further, obtain a high resolution image and also a superb printing performance by adding a silver dissolving component to a wiping solution. SOLUTION: A silver dissolving component is added to a wiping solution. Silver which resides in a non-image part and shows a diminished adhesion is easily removed by wiping a plate face with the wiping solution so that the plate face is prevented from becoming contaminated during starting the printing operation. For this reason, the wiping solution contains a hydrophilic polymer. The hydrophilic polymer is made of a natural product such as various kinds of vegetable sticky material, microbial sticky material or the like, a semi-natural product (semi-synthetic product) such as modified gum, or roasted starches. In addition, the synthetic products are a modified polyvinyl alcohol, a polyacrylic acid derivative, a polyethylene glycol, a polyethylene oxide, a polyvinylpyrrolidone, a vinylpyrrolidone/polyvinyl acetate copolymer and the like.

IPC: G11C11/34
Filed: 1978-09-01
Abstract: PURPOSE: To generate a control signal by automatically detecting variation in power voltage by making a comparison between a power voltage and reference voltage developed by two identical-channel MOSFETs.  
     CONSTITUTION: Two identical-channel MOSFETs 9 and 10 are connected in series between power supply 8 and the earth and power voltage 8 is applied across respective gates to develop a reference voltage at connection point 11 of FETs 9 and 10 without reference to the power voltage. This reference voltage is applied across an inverter composed of MOSFETs 12 and 13, so that a voltage of level L with the power voltage below a fixed value or that of level H with it above the value can be developed. Further, applying this voltage across an inverter at a next stage obtains the inversion output of conection point 14 at output terminal 17. In this way, variation in power voltage is detected by an extremely-simple constitution to make it possible to extract a control signal.
