Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To facilitate work and to enable accurate measurement by integrating an opposed electrode applying AC voltage, a collation electrode detecting a voltage value of AC voltage and an insulating part electrically insulating both electrodes in a rod shape. SOLUTION: A measuring electrode 20 is constituted of a support part 21 becoming a support, an opposed electrode 23, a collation electrode 24, an insulating part 22 insulating both electrodes and a ceramic plate 25 for the continuity with soil. The support part 21 is constituted of a material quality having strength to some degree such as steel and the opposed electrode 23 and the collation electrode 24 are constituted of a conductor such as steel and the insulating part 22 is constituted of insulating matter such as a resin.  A measuring electrode 20 is thrust in a steel pipe in soil to apply definite AC voltage across the opposed electrode 23 and the collation electrode 24 and the impedance between the steel pipe and the opposed electrode 23 is calculated from the voltage applied to the collation electrode 24 and the current flowing through the opposed electrode 23 and the corrosion of the steel pipe is diagnosed from the impedance. Since the opposed electrode 23 and the collation electrode 24 are integrally constituted, a small hole may be bored in a paved surface and work becomes easy and, since both electrodes are held to definite positional relation, impedance can be accurately measured.

Filed: 1992-05-28
Abstract: PURPOSE:To prevent low pressure side from becoming negative pressure and permit stabilized cooling operation at all times by providing a constant pressure chamber equipped with a stopper between the body of a valve and a control chamber. CONSTITUTION:When a temperature in an evaporator is reduced, the temperature in a control chamber 23 is also reduced through a temperature sensitive cylinder 26 and a fine tube 27 while a pressure in the evaporator is also reduced in accordance with it. When the pressure P of refrigerant in the control chamber 23 is reduced, a diaphragm 24 is pushed by the pressure of low pressure side of a diaphragm 22 through a stopper 28 and is displaced toward the side of a cover 25 regardless of the pressure of refrigerant in a constant pressure chamber A in a case when the pressure of the low pressure side is higher than a set pressure. Since the diaphragm 22 is displaced in conjunction with the diaphragm 24 and the stopper 28, a spring receiver 18 is displaced toward the constant pressure chamber A together with an operating rod 30 and a supporting rod 29 by the resilient force of a spring 20 and, accordingly, a valve body 16 is displaced toward a valve seat 15 together with a valve rod 17. Accordingly, the flow rate of refrigerant, which flows from an inlet passage 12 to an outlet passage 13 through a flow passage 14, is limited and the temperature of the evaporator is controlled at a predetermined temperature.

Title: Preignition detecting method
Inventor: NAKADA KOICHI
IPC: F02D45/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous judgment that preignition is recognized as heavy carbonization when heavy carbonization occurs in an ignition plug, by prohibiting the execution of a preignition detecting step in a preignition detection prohibiting step when detecting the occurrence of the heavy carbonization. SOLUTION: Voltage V (ts) at the time of detecting heavy carbonization, stands ready to be read until heavy carbonization detecting time ts is passed away after starting execution, and is read after this standby time is passed away. The voltage V (ts) at the time of detecting heavy carbonization is judged whether or not it is a previously set heavy carbonization detecting voltage Vs or more, and if Yes, heavy carbonization occurs in an ignition plug, and this routine is finished without executing judgment whether or not preignition occurs for avoiding erroneous judgment. When No in the judgment of the voltage at the time of detecting heavy carbonization, it is judged that heavy carbonization is not generated and there is no possibility of erroneous judgment, then the voltage stands ready to be read until preignition detecting time tr is passed away.

Title: Manufacture of bond magnet
Inventor: KIYOMIYA TERUO
IPC: H01F1/08
Filed: 1990-05-29
Abstract: PURPOSE:To improve the reproducibility of the recovery of a magnetic characteristic in a process of manufacture and prevent the magnetic characteristic from decreasing by crushing and classifying a sintered permanent magnet bulk body, sticking a are earth element thereto, sticking an oxidation-resistant material thereto before or after the powdered bulk body is heat-treated, mixing synthetic resin therein, and shaping in a magnetic field and curing the powder. CONSTITUTION:When a sintered R-Fe-B permanent magnet bulk body is crushed mechanically, it is oxidized by ambient gas in a process of manufacture of a bond magnet because the crushed faces are chemically active. The oxidation is protected by coating the powder after classification with rare earth element films and oxidation- resistant films of metal such as Ni and oxide such as Al2O3. Heat treatment of the rare-earth-element-coated powder recovers the inter-face structure of an R-Fe-B main phase and an R rich phase important for recovery of coercive force broken in the crushing and recovers the coercive force approximately as great as before the crushing. Mixing synthetic resin as a binder, shaping in a magnetic field, and curing prevent oxidation by ambient gas in reacting the synthetic resin with the powder, mixing the synthetic resin, shaping in the magnetic field, and curing and prevent the magnetic characteristic from being decreased in the process of manufacture.
