Title: Dc motor
Inventor: NAKAMURA YOSHIMITSU
IPC: H02K13/14
Filed: 1983-02-28
Abstract: PURPOSE:To reduce the wears of a commutator and a brush by using a power source for energizing a coil of a coreless motor through the commutator as an input pulse power source of the type to minimize the counterelectromotive force at the time of switching the coil current. CONSTITUTION:When a current is supplied to a coil 2 of a coreless motor 1 through a commutator 4 and a brush 6, a pulse voltage having a voltage pause time DELTAts is continuously applied from a pulse generation power source 8 for generating a pulse to minimize the counterelectromotive force generated at the inductance of the coil 2 immediately before the current of the coil 2 is switched by the slit 7 of the commutator 4 between the brushes 6. This timing is set by detecting the rotating position of the motor 1 by an encoder or the like. Accordingly, the rotating irregularity can be eliminated by switching the current during DELTAts time, and the wear of a commutating mechanism is largely reduced, thereby increasing the lifetime of the motor.

Filed: 1987-02-17
Abstract: PURPOSE:To reduce the circuit scale of a balanced circuit network by providing the balanced circuit network and varying the resistance of a variable resistor so as to minimize the bypass of a signal from a four line input terminal to a four line output terminal. CONSTITUTION:A balanced circuit network 6' controlled by a hybrid circuit 10 consists of two resistors 16, 17 and a capacitor 18 and the values of the resistor 17 and capacitor 18 are fixed to an average value close to the impedance characteristic of a low frequency region of each 2-wire line connected to the two line input/output terminals 2, 2'. Moreover, the output of the hybrid circuit 10 is branched and inputted to a detection circuit 11 of the signal level and controlled to vary the variable resistor 16 thereby minimizing the bypassed signal level. Thus, the balanced circuit network 6' forms a signal in opposite phase to that of the signal bypassed from the four line input terminal 1 to the four line output terminal 3 to cancel the bypassed signal. Thus, the circuit scale of the balanced circuit network is reduced.

Title: Repairing methdo for refractory lining of converter by hot spraying
Inventor: HAYASE MASAHIRO
IPC: C21C5/44
Filed: 1978-03-24
Abstract: PURPOSE:To increase the effect of repair, by excluding water from sprayed refracotory material in hot spray repair of refractory lining material for a converter. CONSTITUTION:Powdered refractory material for spray made by mixing magnesia clinker etc. with nonaqueous bonding material is sprayed to form a converter lining by means of a dry nozzle 1. At that time, cooling water 5 is introduced through a cooling water intake 3 and is sprayed through small holes 7 made at the top end of the nozzle 1 in order to prevent the oxidation of the hot-spraying material, excessive cooling water being discharged through an exhaust opening 4. In is most pref. that the oxidation is prevented completely by cooling with water, and the water is vaporized just before the cooling water arrives at the surface of the refractory lining. Therefore, it is effective to use 5-7 wt.% cooling water on the basis of hot spray material at furnace temp. of 1,200 deg.C, and at a spray speed 50 kg/min. Use of inert gas, e.g., N2, Ar as the oxidation-preventing medium is also effective.

Filed: 1994-02-04
Abstract: PURPOSE:To improve the real-time properties in a computer graphic system. CONSTITUTION:A cell including an observer is decided (S1), and a stub tree of the cell is obtained (S2). Then this cell is defined as a current one (S3). The information on the objects included in the cell are registered (S4). Then it is checked whether each portal of the cell is closed based on the prescribed data (S5, S6). If each portal is closed, the information on the objects included in the parts interrupted by the closed portals are not registered. Thus the unnecessary data processing can be evaded. If each portal is opened, a cell of a lower rank of the stub tree is defined as a current cell (S7) and the same processing is carried on. Thus it is possible to reduce the quantity of data to be processed and to improve the data processing speed in a computer graphic system.

IPC: F02D45/00
Filed: 1992-02-20
Abstract: PURPOSE:To improve accuracy of presumption by considering influence of characteristic errors of a fuel injection valve in presumption learning control of equal Q region of intake air amount. CONSTITUTION:The coefficient of air fuel ratio learning correction KBLRC in which stationary learnings (steps 33, 39) are carried out has a difference in the equal Q direction. In the case (step 44), the difference is assumed to be caused by the characteristic error of a fuel injection valve and obtained an influence amount alphaLI (n) based on the characteristic error of the fuel injection valve (step 48). A learning value alphaLQ based on the characteristic error of an air flowmeter only is calculated to be stored (step 51). In a running region of low degree of learning progress, a sum of the learning value alphaLQ and influence amount alphaLI (n) provides the coefficient of air fuel ratio learning correction KBLRC.

Abstract: PURPOSE:To obtain the flocculent gold, to reflect irregularly light beams and to give enough decorative effect at a small amount by composing an aggregate of curled metal having specified wire diameter of a specified purity of gold as base material. CONSTITUTION:The gold having a purity >=99.0wt.% is used as base material, and the gold is composed of an aggregate of curled golden wire having wire diameters 10-150 microns. A pure gold lump as base material is rolled repeatedly by grooved rolls to obtain a wire of comparatively large diameter, then, plural rollers are rotated in a warm water bath to draw the wire under a prescribed tension and to obtain a golden wire having a required diameter. A sliding roll 3 rotating with a different peripheral speed V' is arranged between two rolls 2, 2 rotating with the peripheral speed V equal to that of this golden wire and slip is interposed between the sliding roll 3 and the wire 1 to generate the irregular extension. When this is unloosened from a winding bobbin and made free, flocculent gold A is obtained. By this method, the flocculent gold having decorative effect can be manufactured in good workability.

IPC: H01L41/22
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To realize a method for manufacturing laminated electronic components in which relative density as a laminated body is made uniform. SOLUTION: Materials equivalent to green sheet materials are used as supplementary agent for parts other than electrode components on a green sheet 50, so that the thickness of the green sheet 50 can be made uniform, regardless of the presence or absence of any electrode component by this basic means. Also, even when the thickness of the electrode parts is different from that of the other parts on the individual green sheet 50, generation of faults at the boundary part of the electrodes of each green sheet can be prevented synergistically with the close-by green sheet layer by forming supplementary layers 51. Thus, a more inexpensive and more reliable laminate can be formed.
