Title: Method for reducing iron ion
Inventor: MATSUBARA SHIGEO
IPC: C25D21/18
Filed: 1987-01-12
Abstract: PURPOSE:To reduce the Fe<3+> in a plating soln. to Fe<2+>, by charging the plating soln. in the Fe-based electroplating using an insoluble anode into a rotary vessel packed with the particles of Fe or a metal baser than Fe, and tilting and rotating the vessel. CONSTITUTION:The Fe<2+> ion in the electroplating soln. using an insoluble anode is oxidized to an Fe<3+> ion by the O2 in the air or the O2 generated from the anode during plating, and the performance as the plating soln. is deteriorated. The Fe-based plating soln. 6 is charged in the reaction vessel 1 packed with the particles 5 of Fe or a metal such as Zn baser than Fe, the vessel is erected by the action of a bearing 4, and the soln. is agitated by the rotation of a supporting shaft 2. The Fe<3+> ion is reduced to a Fe<2+> ion by the metallic particles 5, and the plating performance is restored. The Fe<3+> ion concn. and pH value in the plating soln. 6 is monitored during the reduction by an oxidation-reduction potential and pH monitoring device 7, hydrochloric acid, etc., are added by a pump 8 when the pH value of the plating soln. 6 increases by the generation of H2, and the operation is stopped when the Fe<3+> ion concn. becomes about 1/50 times the Fe<2+> ion conc.

Title: Battery connection controller for electric car
Inventor: HAYASHI KATSUHIKO
IPC: B60L3/00
Filed: 1994-01-21
Abstract: PURPOSE:To prevent a large discharge current from a battery during reinstallation of a plug by opening a second contact when a maintenance plug is removed under the state where the second contact is closed, which is connected in parallel to a current-limiter resistor and a first contact switching the connection at least between the battery and a target apparatus to be driven. CONSTITUTION:If an output voltage VB of a main battery 12 detected by a voltage sensor 24 is almost 0 [V], that is, if a safety plug 18 is removed, then a vehicle ECU 20 turns off both relays A and B constituting a junction box 22 by means of a contact control signal CONT. As a result, connection between the main battery 12 and an inverter 14 is interrupted. Therefore, even though a safety plug 18 is installed under this state, no large current is produced by charging a capacitor C. By doing this, damages to a maintenance plug due to spark can be prevented thereby improving safety.

Filed: 1990-01-12
Abstract: PURPOSE:To efficiently heat a photosensitive material and to prevent heat from being transmitted to another part by providing a radiation drying part equipped with mutually faced parallel side walls on a reflection board to reflect electromagnetic waves to be radiated from a radiation drying heater. CONSTITUTION:A reflection board 5 is provided so as to surround a radiation drying heater 4 and on the reflection board 5, parallel side walls A are formed. Namely, since the radiation drying part is provided on the reflection board 5 having mutually faced parallel side walls A, the degree of energy arrival to the faced photosensitive material is high and cross sectional efficiency is high as well. Further, radiation is made efficient and simultaneously, radiation to peripheral parts is reduced as well. Thus, the radiation is efficiently executed to the photosensitive material and the influence of heat to the peripheral parts can be suppressed low.

Filed: 1985-01-16
Abstract: PURPOSE:To enable a stable and accurate air-fuel ratio control to be performed by avoiding the input of a false information, such as a noise, through making a judgement that, when a state, in which values measured by an O2 sensor per each unit time are kept in their simple increase or simple decrease, continues over a specified number of times, the operation is decided to be in a steady state. CONSTITUTION:When an engine is in operation, CPU11 inputs through an input port 12 each output signal from an O2 sensor 16, an airflow meter 17, a water- temperature sensor 18, a throttle sensor 19 and an idle sensor 20 respectively. And also, CPU11 outputs, to a fuel injection valve 21, an air-fuel ratio control signal in accordance with a deviation obtained through comparison of the output voltage of an O2 sensor 16 with a reference voltage at the slice level read-out through RAM14. In this case, when a state in which values measured by an O2 sensor per each unit time are kept in their simple increase or simple decrease, continues over a specified number of times, the operation is decided to be in a steady state. And then, a value obtained from said values measured at a specified sequence is considered as an input data for setting a reference voltage at the slice level.

IPC: G01V9/00
Filed: 1992-01-16
Abstract: PURPOSE:To make it possible to stably detect an invader even when a ground state is changed in the winter or rainy weather by covering the periphery of a sensing pipe with a substance which does not easily generate a change in oscillation transmissivity by weather conditions. CONSTITUTION:The substance (oscillation propagating part) 3 capable of suppressing an oscillation transmissivity change due to an environmental change is arranged on the periphery of the sensing pipe 1 filled with liquid. The propagation part 3 is concrete or the like allowed to flow into a groove independently excavated on the ground around each pipe 1 and the pipe 1 is embedded in the concrete. Or the propagation part 3 is concrete allowed to flow into a groove excavated around the whole surface of plural pipes 1 and the plural pipes 1 are embedded in the concrete. Even when the peripheral ground of the pipes are softened by the thawing of frozen ground in the winter, the reduction of the oscillation detecting capacity of the pipes 1 can be suppressed. Since an area contacting with the peripheral ground due to the area occupied by the concrete becomes large, the oscillation detecting capacity can be improved.

IPC: C21C5/30
Filed: 1987-01-13
Abstract: PURPOSE:To permit complete combustion of CO-contg. exhaust gas in a converter and to prevent erosion of a sub-nozzle so as to extend the life of a nozzle for oxygen blowing by mounting the sub-nozzle having a specific shape to the main nozzle for oxygen blowing of the converter. CONSTITUTION:Deficiency of heat for heating the raw materials in the converter is made up by the heat generated by the secondary combustion of the CO-contg. exhaust gas at the time of decarburizing and refining the raw materials contg. scrap cold charge and iron ore at a high compounding ratio to a molten steel by oxygen blowing from the nozzle of the oxygen top blowing lance. The sub-nozzle for secondary combustion which can control the initial velocity of the oxygen in the nozzle outlet to a nonacoustic zone of <=150m/sec is mounted to the main nozzle for oxygen blowing in this case. The angle theta2 formed by the cut face (n) at the top end of the sub-nozzle 2 and the cross section (m) of the nozzle is specified to <=15 deg.. The angle between the cross section l of the main nozzle and the cross section m of the sub-nozzle is designated as theta1 and the angle between the cut face (n) at the top end of the sub-nozzle and the cross section (m) of the sub-nozzle is designated as theta2, then the erosion at the top end (a) of the nozzle increases with an increase in theta2 and, therefore, the above-mentioned angle theta2 is confined to <=15 deg., if possible, to <=10 deg.. The erosion at the top end of the nozzle is thereby decreased and the service life of the nozzle is extended.

Abstract: PURPOSE:To prevent the deformation of an exposed surface by fitting both ends of a glass bulb along the axis, in a sealing member that seals both ends of the opening along the axis of the glass bulb, and by providing recessed parts for fitting that surrounds both the inner and outer circumferential surfaces thereof. CONSTITUTION:Both ends of the opening of a glass bulb 22 are fitted into recessed parts 27a, 27b for fitting of a pair of metal caps 23a, 23b. When the caps 23a, 23b are heated by high frequency induction heating and so on, the both ends of the opening of the bulb 22 that are in contact with the inner surface thereof are melted by the pair of recessed parts 27a, 27b heated at a high temperature. Since the melted glass is regulated by the inner and outer circumferential walls of the recessed parts 27a, 27b the covering of a part of electrode surfaces 29a, 29b by the molten glass that intrudes therein, is prevented. The shrinking of the electrode effective areas of the electrode surfaces 29a, 29b of the caps 23a, 23b, can thus be prevented, as well as the deformation thereof.
