Abstract: PURPOSE:To obtain spherical particles of an amorphous alloy having high out of roundness by injecting molten metal to the specific position on a disc which has good thermal conductivity, and rotates at a high speed with inclination by a prescribed angle to the injection axis of the molten metal and cooling the molten metal quickly. CONSTITUTION:A flat plate-like copper disc 20 is rotated at a high speed by means of a motor 17 via driving shaft 26 and molten metal 12 is injected onto the disc 20. The angle theta assumed by the injection axis 32 of the metal 12 and the plane of the disc 20 in this case is set at 10-60 deg.. The molten metal is injected so as to contact with the surface of said disc within the range of 180-360 deg. azimuth (the third quadrant and the fourth quadrant) in the coordinate system wherein the center X of rotation of the disc 20 is taken at the origin, the rotating direction of the disc is taken in the positive direction of the azimuth and the radius vector located in the relation minimizing the angle assumed by the positive direction of the azimuth at an optional point on the radius vector and the positive direction of the axis 32 is taken in the positive direction of the axis 32 is taken in the positive direction of the X-axis on the plane of the disc 20. The spherical particles or fiber having good symmetricalness are thus obtained.

IPC: C08F12/06
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To enable the production of a high quality sulfonated product in good efficiency without causing thermal deterioration. SOLUTION: Sufonation was carried out at a reaction temperature of 45 deg.C by using a polystyrene having an average molecular weight of about 5,000 dissolved in 1,2-dichloroethane at a concentration of 11% (by weight) as a raw material and liquid SO3 as a sulfonating agent at a molar ratio of the SO3 of 1.15 and then, 15 kg reaction product containing the solvent was introduced into a vibration drier from a feed port at its upper part, and the temperature of the drier was controlled to 90 deg.C and the drier is evacuated so as to have a absolute pressure of about 200 Torr. The solvent began to volatilized and distill out from an outlet at the upper part of the drier. Operation of vibrating the drier was performed and the powder of polystyrenesulfonic acid was collected at the bottom of the drier to obtain 2.84 kg powder.  The yield was 99.5% (by weight) of the theoretical amount of the sulfonated product, and the remaining amount of the solvent was 0.5% (by weight) based on the solid product. The aromatic polymer material having an average molecular weight not smaller than about 5,000 can suitably be used.

Title: Film scanner
Inventor: ITO ATSUSHI
IPC: H04N5/253
Filed: 1995-04-07
Abstract: PURPOSE: To provide a film scanner capable of distributing data processing loads obtained from respective sensors on a time base and improving operability. CONSTITUTION: A picture information acquiring means starts to input picture information synchronously with a signal generated from a 1st perforation sensor 182, momently processes inputted picture information and computes original data for computing a photographing condition. After the end of input of picture information for one frame, information for computing the photographing condition of the frame concerned is transferred to a CPU. On the other hand, a 2nd perforation sensor 184 generates a timing signal for the input of magnetic information after the elapse of carrying time corresponding to about a half frame after the output of the signal from the 1st sensor 182. The reading of magnetic information is started through a magnetic reproducing head 192A synchronously with the timing signal. At the time of completing the reading of magnetic information for one frame, the information is transferred to the CPU. Since time differences are prepared in the transfer timing of respective data to the CPU, the processing loads of respective data in the CPU can be timewisely distributed.

Title: Star type local network system
Inventor: NAKAMURA HARUKA
Filed: 1986-04-09
Abstract: PURPOSE:To improve the utilizing efficiency of the entire network by inhibiting the signal transmission to other repeater when a destination address of a signal from a terminal equipment is concident with the content of the memory. CONSTITUTION:Input signals I-1-I-n from a terminal equipment are compared with contents stored in an address storage memory ADR 3 through a receiver 7 and an OR gate 5 by a comparator circuit 10. When coincident (the same signal passing through the repeater), an AND gate 9 is not opened, a driver 8 is not driven and no signal is sent to a high-order repeater from an output OH. When a signal is given to an input IH from the highorder repeater, the signal is compared with a content of the ADR 3 by a comparator circuit 11. When they are coincident, since the terminal equipment is a terminal equipment connected to the repeater, the signal is sent to all outputs O-1-O-n via a gate 9, a multiplexer MUX 6 and the driver 8.

IPC: B23B5/16
Filed: 1980-06-20
Abstract: PURPOSE:To obtain a desired cutting-in force with a simplified structure by utillizing a centrifugal force applied to a cutting tool by the rotation of a holder for chamfering the inner surface of the pipe material such as a steel pipe. CONSTITUTION:The cutting tool 2 is journalled by the tool holder 1 displaceably through a shaft member 3 on the axial line A...A of the holder 1. The center of gravity G of the tool 2 is eccentric with respect to the axial line A...A. A cutting edge 2a is formed at the end on the side of eccentricity of the tool 2. On the side opposed to the center of gravity G of the tool 2 with respect to the axial line A...A, there is formed a hole 4 into which a resilient member 5 is housed. A change in the centrifugal force caused by the displacement of the tool 2 due to the eccentricity of the inner surface of the steel pipe 10 to be worked is absorbed and compensated by the resilient member 5. Thus, a desired cutting-in force can be obtained by a remarkably simplified structure.

Title: Sound absorption construction and aircraft engine test facility using it
Inventor: NAKAGAWA KIYOSHI
IPC: B64F1/26
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To exhibit favorable sound absorption effect when a noise source is on a nearly fixed position by arranging a plurality of slanted plates slanting against the surface on the surface side of a sound insulating material reflecting sound, and charging sound absorption material made of porous material and the like between the respective slanted plates. SOLUTION: In this sound absorption construction, a plurality of slanted plates 20 slanting against the surface are arranged on the surface side of a sound insulating material 10 reflecting sound. It is constructed so that sound absorption material 30 made of porous material and the like is charged between the respective slanted plates 20. In the case of such sound absorption construction, incident sound S from a noise source reaches the sound insulating material 10 while being absorbed in the sound absorption material 30. The sound is reflected thereat so as to steal out of the territory of the sound absorption material 30 as the reflected sound S1, but the one portion is reflected again by the slanted plates 20 into the sound absorption material 30 to become re-reflected sound S2. Hereby, the course in which the incident sound S passes through the territory of the sound absorption material 30 becomes actually long, and as a result, the sound absorption action is remarkably improved.

Title: Telephone set for loudspeaking voice of opposite subscriber for several seconds after on-hook operation
Inventor: HASHIMOTO KAZUO
IPC: H04M1/60
Filed: 1981-05-31
Abstract: PURPOSE:To call and have a talk with an opposite subscriber successively even when the opposite subscriber puts the receiver on the hook earlier, by reinforcing the voice of the opposite subscriber and holding the talk for several seconds after the on-hook operation. CONSTITUTION:When a telephone set TEL wherein subscriber terminals L<1> and L<2> are connected in the on-hook state, the terminal voltage is forties V, so a high impedance relay Y-1 is energized to put the contact y1-1 in the state shown in the figure. When the telephone set is placed in the off-hook state for calling, the terminal voltage drops and the relay contact is set on the opposite side of the side in the figure, but on-hook operation resets it. Then, the charge in a capacitor C4 is applied to a transistor TRI for a certain period, so the TRI turns on for several seconds. When an opposite subscriber has a talk continuously in this state, its voice signal is amplified by an amplifier AMP and sent out through a speaker SP, so the subscriber listening to it can continue to talk by putting the telephone set in the off-hook state.
