Title: Magnetic brush device
Inventor: KAMIYAMA MITSUAKI
IPC: G03G15/09
Filed: 1981-10-31
Abstract: PURPOSE:To increase the width of a vertical part of a magnetic brush formed on magnetic carriers, and to increase the degree of freedom of a magnetic material, by arraying magnetic carriers in a carrying direction so that plural poles N and S are arranged alternately. CONSTITUTION:A magneic roller 5 has magnets 7 which rotate in the reverse direction to a cylindrical sleeve 6 in the sleeve 6, and those magnets 7 are arranged so that plural magnets, e.g. poles N and S of every two magnets are arranged alternately in a carrying direction (circumferential direction). Therefore, a brush of a developer (a) is formed perpendicularly to the sleve (b) where the poles having the same polarity adjoin to each other, and while the width of the having the same polarity adjoin to each other, and while the width of the brush is increased, the degree of freedom of the developer (a) is increased. Thus, development efficiency is improved and fine lines with low density are reproduced by light slidable friction.

Title: Preparation of poly- o- hydroxy amide
Inventor: REKAI ZECHI
IPC: C08G69/32
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To simply prepare the subject compd. at a low cost without the need to additionally prepare an active carboxylic acid deriv. by reacting a reaction mixture, obtd. by heating a dicarboxylic acid together with a particular compd. in a suitable solvent, with a soln. of bis-o-aminophenol.  
     SOLUTION: A dicarboxylic acid is heated together with a sulfonic acid chloride and a tertiary amine in a suitable solvent to a temp. of 80°C or above (step A), the resultant reaction mixture is reacted with a bis-o-aminophenol soln. at a temperature below 80°C to prepare a poly-o-dydroxyamide (step B). In the above reaction, the step A is conducted at a high temp., while the step B is conducted at a relatively low temp., enabling the selectivity for an amide to be made higher than that for an ester. Thus, an alkali-soluble poly-o- hydroxyamide can be simply prepared from a dicarboxylic acid and bis-o- aminophenol at a low cost without additionally preparing an active dicarboxylic acid deriv.

Title: Manufacture of thin film platinum temperature sensor
Inventor: ONAKA KAZUHIRO
IPC: H01C7/02
Filed: 1989-07-07
Abstract: PURPOSE:To easily form a microscopic pattern by a method wherein, after the surface of a platinum thin film has been treated with chlorine, the surface of the platinum film is coated with an organic compound by having an organic solvent, with which an ion-exchange reaction is generated, to come in contact with the treated surface of the platinum film. CONSTITUTION:The surface of a platinum film 1 is treated by dipping the film 1 into the mixed solution consisting of 3N chlorine and hydrogen peroxide solution of 0.1N. Then, an organic compound is coated on the platinum film by allowing chlorine-treated polymeric amine (R2NHCl) to come in contact with the platinum film 1. A resist is coated thereon, and after conducting exposing and developing operations, the above-mentioned material is hardened by heating. As a result, the surface tension against the resist-ink-coated platinum film is reduced, and at the same time, the close contact of resist against the platinum film can be improved by preventing the moisture from coming into contact with the surface of the platinum film. Accordingly, a microscopic pattern processing can be accomplished easily.

Title: Superconductive rotary pump
Inventor: TATSUNO HIYOSHI
IPC: F04C15/00
Filed: 1988-07-14
Abstract: PURPOSE:To miniaturize and strengthen a pump by arranging a superconductive magnet in a rotator and a superconductive coil in a casing in which the rotator is stored. CONSTITUTION:A superconductive magnet 9 is formed on a periphery of a toothed wheel 6 of a gear pump 8, being embedded, for instance, in each tooth. A superconductive coil 10 is arranged on the side of a casing 1 as opposed to the superconductive magnet 9. The superconductive coil 10 is connected to a power source through a switching means which is switched synchronously with the turning of the toothed wheel 6. When the superconductive coil 10 is connected 10 the power source through the switching means, turning force is generated by means of magnetic force generated at the superconductive coil 10 and that at the superconductive magnet 9, and the toothed wheel 6 is turned. As the toothed wheel 6 is turned, a toothed wheel 5 that is engaged thereto is also turned, and the liquid introduced into the casing 1 from an inflow port 2 is thus pushed out from an outflow port 3.

Title: Automatic frequency control circuit
Inventor: KURIHARA SHIGERU
IPC: G01S7/28
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To miniaturize a reception device by allowing a reception antenna to sweep a control voltage in an AFC adjustment period and change a local oscillation frequency and outputting the optimum control voltage value corresponding to the maximum value of the pulse width time of video signal change to a local oscillator. SOLUTION: A trigger signal that is generated at every transmission of radar and an azimuth signal that is updated every time a radar antenna rotates by a unit angle are inputted to a control voltage sweeping/optimum value retention circuit 10 and a gate circuit 4. The control voltage sweeping/optimum value retention circuit 10 supplies a control voltage for changing an oscillation frequency to a local oscillator 8 while an antenna azimuth is in gate period. The gate circuit 4 takes out only a video signal while the control voltage changes from itself and outputs it to a pulse width conversion circuit 5.  Then, the control voltage sweeping/optimum value retention circuit 10 obtains the average value of data in the same azimuth based on pulse width information being stored in a storage circuit 7, calculates data with stable azimuth versus pulse width, and performs the optimum value retention processing of the control voltage.
