Title: Method for deciding using life of lead accumulator
Inventor: IKUTA KOJI
IPC: G01R31/36
Filed: 1990-02-22
Abstract: PURPOSE:To accurately measure internal impedance and to surely decide the using life of a lead accumulator by measuring the frequency of a ripple current included in the charging current of the accumulator connected to a floating charging state through a rectifier. CONSTITUTION:A ripple current frequency detector 5 is inserted into the charging route of the lead accumulator 3, the output of the detector 5 is inputted to an internal impedance measuring instrument 6 and the output of an AC constant current source 61 in the instrument 6 is adjusted so that the frequency of a measured current is less than the frequency of the ripple current. When the voltage between the terminal of the accumulator 3 into which the constant current to be the measuring current for the frequency is allowed to flow is measured by an AD voltmeter, the internal impedance of the accumulator 3 can be calculated. Since the internal impedance can be accurately measured, the using line of the accumulator can surely be decided.

Abstract: PURPOSE:To realize smooth key depressing operations by fitting iron cores to keys through automatic core adjusting mechanisms provided on the back of the keys and allowing the relative movement between the keys and iron cores, and inclinations of the iron cores against the keys by means of the mechanisms. CONSTITUTION:An iron core 19 is fitted to a key 1 through an automatic core adjusting mechanisms 37 provided on the back of the key 1 and a degree of freedom is given to the fitting position of the iron core 19, namely, provided position of an electromagnetic actuator 20 without giving any influences to the appearance of the key 1. The iron core 19 fitted to the key 1 is allowed to move in a plane which is almost perpendicular to the key depressing direction and to incline against the key 1 by means of the mechanism 37. Therefore, even if a little error is produced in the front-back and right-left directions when the iron core 19 is fitted to the key 1 or due to an environment change after fitting, the error is automatically corrected and the core 19 is adjusted to the state where the axial center is aligned to the solenoid 17 of the actuator 20.

Abstract: PURPOSE:To measure the distribution of a magnetic substance through the measurement of a magnetic field by giving an external magnetic field to a reagent, measuring the distribution of a magnetic field change in a reagent vicinity to accompany the magnetic substance distribution in the reagent and data-processing the measured value. CONSTITUTION:When a compensating coil 5 is fixed and a pick-up coil 4 is scanned in an (x) direction at a constant speed, an output signal V of a skid magnetometer is outputted in making the (x) direction distribution of the magnetic field change in the (x, y) position of the pick-up coil 4 into the function of a time. A sample and hold circuit 11 samples it for a fixed time, the sample is fetched through an A/D converter 12 to a CPU 13, and it is stored into a memory 14. Next, exciting coils 1 and 2 are rotated at fixed angles around a reagent 3, and a distribution P2(x, y) of the magnetic field change is obtained in the same way as above. A distribution P(l, m, n) of the magnetic field change extracted in such a way can be considered as the sum of the magnetic field change due to the magnetic substance distribution and the magnetic field change generated by a current (neural current) to flow in an organism. Next, the magnetic substance distribution is calculated from the distribution measuring value of the magnetic field change.

Title: Air-fuel ratio control
Inventor: AMANO MATSUO
IPC: F02D41/12
Filed: 1984-03-10
Abstract: PURPOSE:To prevent the deterioration of exhaust gas in sharp deceleration by carrying-out the correction on sharp deceleration added with the stationary learning in air-fuel ratio control. CONSTITUTION:An air-fuel ratio controller which performs feedback control according to the concentration of a specific component in exhaust gas carries- out stationary learning control when operation state does not vary. When sharp decleration is detected from the fundamental fuel injection amount, the correction in sharp deceleration (correction by shift coefficient Ks) is carried-out. In the correction by the shift coefficient Ks, the fuel injection amount is reduced in consideration of the adhession of fuel onto wall surface. The chart is a flow chart for obtaining the shift coefficient by the learing in sharp deceleration. Thus, the deterioration of exhaust gas in sharp decleration can be prevented.

Filed: 1991-03-11
Abstract: PURPOSE:To ensure the output balance of right and left banks by cooling a substantially U-shaped curved portion of one duct part which is arranged in the upper direction of a cooling fan by the use of outside air.

Title: Sodium refining device
Inventor: SHIMOYASHIKI SHIGEHIRO
IPC: G21C19/30
Filed: 1984-03-08
Abstract: PURPOSE:To remove impurities and corrosion products in Na and to permit easy regeneration of a mesh made of a permanent magnet consisting of ''Alnico'' by passing liquid Na as a coolant for a fast breeder through said mesh. CONSTITUTION:Liquid Na as a coolant to be used in a fast breeder contains impurities such as O2, N2, C, etc. and radioactive corrosion products in an increasing concn. during repetitive use and therefore such Na is fed into a refining vessel 41 through an inlet 42 thereof and is passed through the inside of the vessel 41 packed therein with a mesh 44 consisting of an ''Alnico'' permanent magnet of which the magnetic force weakens at a high temp. A temp. gradient is preliminary given to the inside of the vessel 41 in such a way that the temp. decreases from the upper part toward the lower part. As the Na supplied at a high temp. flows downward, the impurities and corrosion products having magnetism are attracted away to the mesh 44 by which Na is refined. When impurities, etc. accumulate on the mesh 44, the temp. is increased by a heater 48 to weaken the magnetic force of the mesh 44 and to desorb away the impurities sticking thereto. The mesh 44 is then cooled by a cooling cylinder 51 and is energized by a coil 49 by which said mesh is again magnetized and thus regenerated.
