Title: Method and apparatus for producing needle-like amorphous metallic powder
Inventor: KAWAMURA YOSHITO
IPC: B22F9/10
Filed: 1986-03-19
Abstract: PURPOSE:To obtain effective amorphous metallic powder under high productivity when used as a raw material for a high-performance magnetic material and composite material by bringing a mist-like molten metal into collision against a slope forming a conical recess of a high-speed rotating drum and solidifying the molten metal. CONSTITUTION:An alloy block of crystalline Fe-B-Si which is a raw material is put into a crucible 11, and after gaseous Ar is introduced therein, the raw material alloy 14 is subjected to high-frequency induction heating 13 to about 1,300 deg.C higher than about 1,100 deg.C m.p. thereof. The gaseous Ar flow is kept ejected 25 and the pressure of the gaseous Ar is increased in the crucible 11 to discharge 112 the raw material alloy in the form of thread-like molten metal flow 141, by which the mist-like molten metal 142 is formed within the space A. The molten metal 142 is then brought into collision against the slope 33 of the rotary drum 31 under high-speed rotation and is pressed to the slope 33 by the component of force F1, in the direction perpendicular to the slope, of the centrifugal force F acting toward the outside of the slope 33. The molten metal is at the same time elongated approximately in the circumferential direction by the component of force F2 in the slope direction and the high-speed rotation of the slope 33 itself. In addition, the molten metal is quickly cooled and is solidified as needle-like amorphous metal. The objective needle-like amorphous metallic particles 143 are thus obtd.

Title: Motor controller
Inventor: SUZUKI TATSUO
IPC: H02P29/40
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To eliminate need for feedback of motor driving current, and make compensation for a control system characteristic change due to disturbance by compensating the change of a speed error signal based on a speed feedback indicating rotational speed. SOLUTION: A variable voltage limiter 2 adjusts output signal voltage of a calculating part 11, according to the output limit value of a current estimation observer 6 if it is estimated that overcurrent is running through a motor coil 3, to a preset limit value during the proper operation of a motor based on the estimated result of a current estimation observer 6. The obtained signal is outputted into a subtracting part 12 and the current estimation observer 6. The subtracting means 12 outputs an error signal between the output signal of a variable voltage limiter 2 and an inductive voltage signal obtained by multiplying an inductive voltage constant Ke to drive a motor and generate torque corresponding to a torque constant Kt. A rudder blade is rotated according to the error torque between torque through a torque limiter 4 and air load torque 9.

Title: Flaw detector with magnetic particle
Inventor: KAMIMURA SHIGENORI
IPC: G01N27/84
Filed: 1979-05-18
Abstract: PURPOSE: To heighten the accuracy of inside surface flaw detection of a steel pipe through a simple apparatus, by adopting a coil method together with a pole gap method employing a magnetic core.  
     CONSTITUTION: The first and second coils 4, 5 are wound around a magnetic core 3. The first coil 4 is spirally wound in the circumferential direction of the core 3. The second coil 5 is shaped as a single conductor plate 5a extending around the core in its axial direction. When a three-phase alternating current is caused to flow through the coils, magnetic flux is generated in the axial and the circumferential directions of a steel pipe 1. This results in enabling the detection of flaws extending within the thickness of the steel pipe in all directions such as the axial and the circumferential directions of the pipe.

IPC: G03G9/097
Filed: 1983-04-07
Abstract: PURPOSE:To prevent changing of a triboelectrification amt. even if strong pressure is applied at the time of spreading a toner to maintain copy quality constant by incorporating a specified quaternary aminoalkyl ester in a hard material used for a microencapsulated toner. CONSTITUTION:A quaternary aminoalkyl (meth)acrylate is incorporated in the hard material of microcapsules composed of a soft material and the hard material for coating it. The obtained insulating nonmagnetic toner 3 is spread on a toner carrying roller 2 regulated in thickness thinner than the gap between a latent image bearing drum 1 and the roller 2, and carried to a developing section. An alternating electric field is applied there to the toner 3 to develop the latent image. A part of triboelectrified amt. disappears through a cationic amino resin present on the surface of the toner 3 by the addition of quaternary aminoalkyl (meth)acrylate to the hard material of the microencapsulated toner 3, even when strong force is applied and highly triboelectrified at the time of spreading the toner 3. As a result, rise of a triboelectrified amt. with time can be prevented, a constant charge is given to the toner, and image density is also kept constant.

Title: Silver halide emulsion
Inventor: YAGI TOSHIHIKO
IPC: G03C1/035
Filed: 1983-04-11
Abstract: PURPOSE:To enhance sensitivity and to improve graininess sharpness by incorporating a core/shell type silver halide obtained by reacting a water-soluble silver salt soln. with a water-soluble halide soln. in the presence of a silver halide solvent and growing the obtained seed crystals to a specified range of grain diameter. CONSTITUTION:A water-soluble silver salt soln. is reacted with a water-soluble halide soln. in the presence of a silver halide (AgX) solvent and the obtained AgX seed crystals are grown, and the obtained core/shell type AgX having <=0.5m average grain diameter is incorporated in an emulsion. The core/shell type emulsion obtained by growing the AgX seed crystals in an AgX solvent is extremely high in sensitizing effect. As the grain diameter ratio of emulsion grains to seed crystals, a ratio of >= about 1.1:1 is found to be effective, and the upper limit of the growth ratio is about 10:1. Such an emulsion is good in graininess and sharpness, and yet, restrains occurrence of fog, and enhances sensitivity extremely.

IPC: A63F7/02
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To receive compensation for the occurrence of a power failure in a specific game state after restoration by subtracting the number of prize balls, which are not paid out due to the power failure in the state of a specific game state, so as to calculate the number of prize balls to be compensated for, and storing the calculated result in connection with player's identification information. SOLUTION: When a power failure detection circuit 30 connected to a power source circuit 29 detects a voltage lower than a fixed value at the time of being in a special prize state, a CPU 25 judges it to be a power failure and continues the special prize state while confirming the presence/absence of an interruption signal for reporting the fact. Then the number of the prize balls, which is actually paid out by a prize ball paying out device 43 until the time point and counted by a prize ball detecting sensor 35, is subtracted from the scheduled number of the prize balls read from a RAM 27 at this time to calculate (the difference between the number of the balls and the number of the balls to be compensated). This difference in the number of the balls is stored in an EEPROM 28 in connection with player's identification information.  Thereby, at the time of energizing after the occurrence of a power failure, the playing customer is compensated correspondingly to the number of the compensating balls to eliminate a loss.

Abstract: PURPOSE:To improve the reliability and the durability as well as to suppress abrasion or damage by providing a driving means to shift-operate a shift member through a transmission system of operation force and an energizing means which consists of a plurality of belleville springs placed on the way of the transmission system. CONSTITUTION:When an actuator is operated, the operating force is transmitted through a rod 109, a fork 105, and a pressing member 95, and a sleeve 43 is shifted to the left. In this case, when the phases of splines are not fitted in a contact breaking mechanism 91, a spring 111 and a return spring 129 act as a waiting mechanism. The return spring 129 furnishes belleville springs 131 in series, and the spring 111 lines up two sheets of belleville springs 133 superposed. By arranging the belleville springs 131 and 133 in series, the load is presented in almost a constant area responding to the variation of deflections. By putting the scope of all the practical deflections in this area, an almost constant energizing force can be obtained from all the deflections of the springs 111 and 113.
