Title: Manufacture of sintered magnet
Inventor: NAKAZONO IZUMI
IPC: B22F3/12
Filed: 1985-03-19
Abstract: PURPOSE:To control friction appearing between a molded body and a metallic mold, and enable industrial mass production of Nd-Fe-B permanent magnets based on by changing a mixture of raw material powders and zinc stearate into the molding space, subjecting the mixture to magnetic orientation and sintering process, followed by heat-treatment. CONSTITUTION:Molding raw material powders, which have been obtained by mixing raw material powders of 1-50mum mean grain size with zinc stearate in the range of 0.005-0.1wt%, is charged into the molding space, oriented in a magnetic field, molded, sintered at a temperature ranging from 900-1,200 deg.C and subjected to heat-treatment. If the added amount of zinc stearate is below 0.005wt%, little is improved in molding efficiency and reducing friction between the metallic mold and the molded body. On the other hand, if that amount exceeds 0.1%, the magnetic property of the sintered magnet obtained deteriorates significantly to lose a feature possessing such a high energy produce reaching 45MGOe as in the case of permanent magnets of a Fe-B-R family.

Title: Production of aqueous polyester dispersion
Inventor: KUNO SHINYA
IPC: C08G63/91
Filed: 1995-03-15
Abstract: PURPOSE: To obtain a highly concentrated aqueous polyester dispersion by kneading a water-dispersible polyester having a small amount of sulfonic acid (metal salt) groups (bonded especially to the aromatic nucleus of a dicarboxylic acid) and water to form a homogenous translucent product and diluting the product with water. CONSTITUTION: While water is being added to a water-dispersible polyester resin having sulfonic acid (metal salt) groups, they are kneaded until the phase inversion point (at which the product becomes translucent) is passed. The product is further diluted with water to prepare an aqueous polyester resin dispersion. Although the sulfonated polyester can be synthesized by various methods, it is advantageous to adopt a method comprising reacting a sulfonated polycarboxylic acid such as the one obtained by sulfonating an aromatic polycarboxylic acid such as phthalic anhydride with a polycarboxylic acid and a polyol. It is essential that at least 40mol% wholly aromatic dicarboxylic acid is used, and 0.2-0.6 meq/gr of sulfonic acid groups are introduced thereto. The obtained aqueous polyester resin dispersion is a microdispersion which can give a coating film excellent in water resistance.

IPC: G08B13/18
Filed: 1984-03-24
Abstract: PURPOSE:To improve the efficiency of condensation of infrared rays and to make it possible to set an area of detection in proximity, by forming a condensing means of a plurality of concave mirrors whose optical axes are diverged in the direction of condensation and whose focuses are made to coincide together, and of a small-sized concave mirror which is provided in the vicinity of the focuses of said concave mirrors in such a manner that the reflecting surface thereof is opposite to those of these mirrors. CONSTITUTION:In the vicinity of the focus of a main reflecting mirror 1 composed of a plurality of concave mirrors 1a and 1b and having an infrared ray detector 2 disposed in the central part, a subordinate reflecting mirror 3 formed of a small-sized concave mirror and provided in such a manner that the reflecting surface thereof is opposite to that of the main reflecting mirror 1 is disposed to form a condensing means together with this mirror 1. Since the subordinate reflecting mirror 3 is disposed between incident infrared rays A and B each being parallel to an optical axis of light coming from an area of condensation by each of the concave mirrors 1a and 1b, e.g. from each area of detection, the fall of the efficiency of condensation due to the shadow of the subordinate reflecting mirror 3 is prevented. Moreover, since the subordinate reflecting mirror 3 is disposed in the vicinity of the focus of the main reflecting mirror 1, the angular aperture of the axes of the concave mirrors 1a and 1b of the main reflecting mirror can be made small, and thus the area of detection can be set proximity.

Title: Serial/parallel conversion circuit
Inventor: MORIZAKI SHIGEKI
IPC: H03M9/00
Filed: 1990-03-08
Abstract: PURPOSE:To warrant a conversion function even when a frame signal is changed by applying serial/parallel conversion in response to a timing signal from a gate circuit when each frequency division output of a counter circuit goes to all active. CONSTITUTION:Since a signal line being connected to ground is connected to the data input terminal of a counter circuit 6, when the frame signal from a frame input terminal 2 is inputted to a data load control input terminal LD, the output signal from data output terminals Q1-Q3 goes all to a low level. That is, the value counted by the signal from a clock input terminal 3 to a clock input terminal C is reset by inputting a frame signal to the terminal LD. When the frame signal is inputted to the terminal LD of the circuit 6, the signal is delayed by 8 clocks at the circuits 6, 7 and the result is inputted to a demultiplexer 5, the frame signal is inputted for each 8 clocks, a conversion data is outputted from the output terminal 4. Thus, the serial/parallel conversion function is warranted.
