IPC: C09K3/14
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain a thermosetting composition excellent in fading resistance and capable of giving a friction material producing little noises by compounding a phenolic resin with granules of polyurethane-polyurea resin cured material. SOLUTION: This resin composition is obtained by compounding (A) a phenolic resin (preferably, powdery resin) with (B) granules of a cured polyurethane- polyurea resin (preferably, spherical granules of 0.1-50μm in particle diameters), preferably 5-30 pts.wt. of the component B based on 100 pts.wt. of the component A.  The component B is obtained e.g. by finely dispersing a hydrophobic organic phase, which is obtained by mixing a polyisocyanate compound with a polyhydroxy compound in such a manner that the isocyanate group is stoichiometrically excess and can form three dimensional bridges by reaction, in an aqueous phase containing protective colloid, subsequently adding a polyamine to the aqueous dispersion liquid in an amount of equal to or less than equivalent based on the excess equivalent of the isocyanate, and carrying out an interfacial polymerization and an intra-granular urethanization reaction.

Abstract: PURPOSE:To perform efficiently reduction of Fe<3+> ions with a small sized installation by bringing powders of metallic Fe and metallic Zn into contact with a plating soln. contg. an Fe<3+> ion under solid-to-solid contact with each other. CONSTITUTION:Fe<3+> is formed on the electrode surface of an insoluble anode 2 when a material 3 to be plated is plated by conduction of electricity in a plating cell 1 filled therein with a plating soln. consisting essentially of an Fe<2+> ion and a Zn<2+> ion. A prescribed amt. of the plating soln. is withdrawn from the tank 1 through a withdrawal pipe 9 into a reducing pipe 6; at the same time, the plating soln. is brought into contact with the added powder or grains 5 of metallic Fe and metallic Zn. The powder 5 dissolves in the plating soln. and reduces the Fe<3+> ion; at the same time, the reduction is accelerated by the mutual galvanic effect to be resulted from the solid-to-solid contact between the dissimilar metals. The plating soln. is then treated with a solid-liquid separator 7 to remove sludge and is introduced into a buffer tank 4. The compsn. of the plating soln. is adjusted there and is recirculated into the cell 1.

Filed: 1988-07-29
Abstract: PURPOSE:To effectively prevent the defective assembling of a head from being generated and to prevent yield in the assembling work of the head from being lowered by forming an adhesive layer on a plane where a terminal board is stuck and fixed, loading the terminal board in which the adhesive layer is formed at a prescribed position on a head base plate, and after that, fixing the terminal board on the head base plate by melting the adhesive layer. CONSTITUTION:The adhesive layer 34 is formed on the back plane of a board 30, and is molded and comprised fitting in the shape of the head base plate 21. The adhesive layer 34 is provided with adhesive strength possible to perform the temporary fixing of the terminal board 29, and the dimension of the adhesive layer 34 is formed less than the outside dimension of the terminal board 29.

Title: Starter for single-phase induction motor
Inventor: ABE TAKASHI
IPC: H02P1/44
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To obtain a starter which allows auxiliary winding to be separated with a number of revolutions corresponding to a power supply frequency, using an electric circuit. SOLUTION: When a rotor 13 is rotated, an electromotive force VI in proportion to the product of the number of revolutions N of the rotor 13 and the magnetic energy B produced in main winding 11 is generated in auxiliary winding 12. Since the electromotive force VI is low when a motor 1 is started, therefore, a switching circuit 25 is turned off then, which connects a single-phase power supply VS with the auxiliary winding 12, and starting torque T is produced. Then the rotor 13 is rotated by the starting torque T. When the electromotive force VI is increased to a certain value as a result, the switching circuit 25 is turned on, and the single-phase power supply VS is separated from the auxiliary winding 12.  Since the electromotive force VI is in proportion to the reciprocal of power supply frequency (f) the single-phase power supply VS and the auxiliary winding 12 are separated from each other always with a number of revolutions N0 corresponding to the power supply frequency (f).

Title: Automatic white balancing circuit
Inventor: UEHARA MASAO
IPC: H04N9/73
Filed: 1983-10-14
Abstract: PURPOSE:To make a high-precision adjustment according to an optional fluorescent lamp by adjusting white balance with the signal generated by detecting a ripple of a fluorescent lamp light source stored in an object light source and color temperature information from a color temperature detecting means. CONSTITUTION:Signals iR and iB of red and blue detected by a milk white diffusing plate 8 are amplified logarithmically and the difference between both logarithmic signals is obtained by a differential amplifier 12, whose output signal is led to a ripple detecting circuit 21 and an LPF26. The circuit 21 extracts a ripple component with a period twice as long as that of the commercial frequency and makes it into a direct current to output logic 1 to a coincidence circuit 25 when a fluorescent lamp is used as a light source 4. The LPF26 supplies a window comparator CP27 with a signal obtained by excluding the ripple component from the output signal of the amplifier 12. The CP27 impresses logic 1 to a circuit 25 when the input signal is within the set color temperature range of the fluorescent lamp, and the circuit 25 outputs logic 1 to a white balance adjusting circuit 7 when both input signals coincide with each other. The circuit 7 controls the gains of amplifiers 4 and 6 for the signals of R and B to correct the deviation of adjustment of the white balance.
