Title: Instantaneous heating method
Inventor: SUZUKI YOSHIKAZU
IPC: F27B17/00
Filed: 1988-08-26
Abstract: PURPOSE:To attain a high temperature in a short time and to facilitate the high-temperature thermal reaction under a particular environment by contacting a heating object with a compressed powder mixture of Ni and Ti and quickly heating from external source under reduced pressure to induce the self exothermic reaction of the compressed powder. CONSTITUTION:A powdery mixture consisting of 49-56atom% of Ni powder having an average particle diameter of 0.5-10mum and 51-44atom% of Ti powder having an average particle diameter of 10-100mum is pressed to obtain a compressed powder mixture 4 having a density of 3.5-5.5g/cm<3>. A heating object 5 is put into a graphite crucible in a state covered or contacted with said compressed powder 4 and the crucible 3 is placed in an externally heated furnace 1. A silica tube 2 is connected to an evacuation system to evacuate the space in the furnace 1 and, at the same time, the heating object is externally heated to a melting and alloying temperature (810-840 deg.C) at a heating rate of >=35 deg.C/min to induce self-exothermic reaction of the compressed powder 4. The specimen 5 is instantaneously heated at a temperature above the external heating temperature to effect the reaction of the specimen.

Title: Method for monitoring corrosion of metal
Inventor: ISERI HAJIME
IPC: C23F11/00
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To predict corrosion of an anti-corrosive metal highly accurately and estimate a reason therefor quickly by measuring both a change of a corrosion potential of the anti-corrosive metal in a liquid and a deposition amount of dust. SOLUTION: In order to monitor corrosion of a metal in a cooling water system or the like, for example, a test water is supplied at a constant flow rate to a test tube 1 using a stainless steel to be tested, a potential of a reference electrode 2 of a silver-silver chloride electrode or the like and the tube 1 is measured as a corrosion potential by a potential-measuring apparatus 3, and at the same time a differential pressure corresponding to the amount of dust deposited in the tube 1 is measured by a differential pressure-measuring apparatus 4. When an increase of the differential pressure corresponds to an increase of the corrosion potential, the increase of the corrosion potential is estimated to result from the adhesion of dust components. When only the corrosion potential increases, the increase is estimated to result from components of the test water.  Countermeasures to cope with respective reasons can accordingly be selected. Alternatively, dust of a metallic face where the potential is measured can be directly measured to monitor corrosion.

Title: Control unit for resonance type electromagnetic vibrator
Inventor: NONAKA TAKEYOSHI
IPC: B65G27/32
Filed: 1981-12-28
Abstract: PURPOSE:To aim at a reduction in power consumption, by controlling frequency of the exciting force of a resonance type electromagnetic vibrator so as to be adjusted to the characteristic frequency of the said vibrator, while also controlling the magnitude of the said exciting force so as to cause transport speed of the subject body of the said  vibrator to be adjusted to the desired speed. CONSTITUTION:When load is imposed on a trough 2, amplitude of the trough 2 tries to become smaller, consequently the resonance frequency in a vibrating system inclusive of the load falls off. At this time, the value possessed by the trough 2, being obtained by multiplying amplitude by the frequency of the exciting force is detected and compared with the set transport speed by means of a comparator 14, through which an AC DC converter 5 produces a DC output in order to meet this set value at all times, so that even in a loaded state, the trough vibrates in such amplitude as capable of securing the desired transport speed. Simultaneously, phase difference between an exciting force and the amplitude is detected and compared with the set phase value by means of a comparator 10 and since the frequency in the AC output of a DC AC converter 7 is so controlled as to become this phase value, a state of resonance can be thus maintained.

Title: Power feeder system impedance reduction method, circuit board and electronic equipment
Inventor: YOKOTA HITOSHI
IPC: H05K1/16
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To suppress antiresonance on a circuit board and to reduce power feeder system impedance and EMI(electromagnetic interference). SOLUTION: In this circuit board 30 of a multi-layer structure composed of a planar ground pattern and a power source pattern and provided with a power feeder system, thin and long conductive paths 32b for connecting the corner part of the ground pattern and the center part of a side are formed by forming plural slits 32a along the peripheral part of the ground pattern, resistance elements 37 and 38 are arranged in the middle of the respective conductive paths 32b, and the corner part of the ground pattern and the center part of the side are short-circuited through the resistance elements 37 and 38. Since the antinode and node of the standing waves generated in the ground pattern or the antinode and a part corresponding to the antinode are short- circuited at the time of feeder power to an IC 35 and an LSI 36 mounted on the circuit board 30, noise power by the standing waves is offset, and the antiresonance by the standing waves and the increase of the power feeder system impedance are suppressed.

Title: Fuel supply system of in-cylinder direct injection type internal combustion engine
Inventor: KANO MASAO
IPC: F02D41/06
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To quickly increase fuel injection pressure when a high-pressure fuel pump of an in-cylinder direct injection type internal combustion engine cannot yet generate sufficiently high fuel pressure immediately after the engine has been started. SOLUTION: During startup of an engine, discharge pressure of a low-pressure fuel pump 26 is directly supplied into a large-diameter cylinder 22c of a pressure intensifying piston mechanism 22. A large-diameter piston 22a receives the pressure and pressurizes fuel within a small-diameter cylinder 22d via a small- diameter piston 22b integrally formed therewith. Thus, the fuel pressure within a fuel delivery piping 29 to be supplied to a fuel injector 20 is quickly increased. Accordingly, excellent fuel spray can be provided by high fuel pressure from immediately after the startup. When the number of revolutions of a high-pressure fuel pump 24 is increased and thus the fuel pressure within the large-diameter cylinder 22c is increased, a main outlet port 22f is opened and high-pressure fuel is directly supplied into the fuel delivery piping 29.  Thus, the engine is brought into a normal operating condition.

IPC: B60L15/40
Filed: 1990-08-15
Abstract: PURPOSE:To reduce the changing time of notch by periodically judging whether a vehicle reached to starting condition of brake control operation and performing stop control through fuzzy inference when the vehicle reaches to the brake control starting condition. CONSTITUTION:Brake control takes place when the start marging time of brake control, obtained based on the distance L1 from current position to a target point O, current speed VT1 and an expected acceleration betap, after passage of a vehicle through point P separated by a distance (l) to this side from the target point O becomes shorter than a predetermined value. In other words, distances Lz, LP, LN between an expected stop point and the target point, for current notch, single notch increment and single notch decrement, are obtained based on L1, VT1, current acceleration alphaT1 and variation of acceleration DELTAalpha for single notch change. Then a fuzzy amount mu1 for allowing stoppage within allowable error and a fuzzy amount mu2 for allowing accurate stoppage at the target stop position, corresponding to thus obtained distances, are determined through a membership function. Then a notch for providing the maximum value is selected between mu1 and mu2.
