Filed: 1988-02-17
Abstract: PURPOSE:To make dissipation of generated gas easy and to enable plating at low voltage and also to prevent build-up unevenness of plating by making a steel sheet carried in a plating bath to a cathode and utilizing a specified perforated metallic anode and performing electroplating treatment. CONSTITUTION:A steel sheet 4 is continuously electroplated by making the steel sheet 4 transferred in an electroplating tank 1 to a cathode and utilizing the perforated metallic anodes 5, 6 having a coated layer consisting of activated electrode substance parallel thereto. The anodes 5, 6 are an electrode in which the base material is expanded metal and a coarse-hole network body consisting of metal such as Ti and Zr forming a passive film and has a coated layer of activated electrode substance incorporating metallic oxide of platinum group especially iridium oxida. Gaseous oxygen generated at a time of electrolysis is easily dissipated because the electrode is perforated by utilizing this electrode as the anodes 5, 6 and plating of the steel sheet 4 can be performed at low voltage and also current density is raised and therefore the carrying velocity of the steel sheet 4 is made high and productivity can be enhanced.

Title: Organic electrolyte battery
Inventor: OKAMOTO OSAMU
IPC: H01M4/58
Filed: 1982-03-06
Abstract: PURPOSE:To prevent any increase in the internal resistance of an organic electrolyte battery which might be caused during preservation of the battery by suppressing the polymerization of a cyclic-ether-system organic solvent by performing amine treatment on iron sulfide used as a positive active material so as to neutralize the acid group existing in the surface of said iron sulfide. CONSTITUTION:In an organic electrolyte battery, a negative electrode 7 is prepared by using a light metal such as lithium as a negative active material, a positive electrode 1 is prepared by using iron sulfide the acid group existing in the surface of which is neutralized by amine treatment as a positive active material, and electrolyte is prepared by using a cyclic-ether-system organic solvent as a solvent. In addition, such an organic electrolyte battery is constituted by the combination of a separator 4, a positive can 3 and a negative can 5. Therefore, since the amine treatment is performed on the above iron sulfide, any reduction of the electric conductivity of the battery which might be caused due to the polymerization of the cyclic-ether-system organic solvent caused by the acid group existing in the surface of the above iron sulfide can be prevented. Consequently, the preservation performance of the battery can be improved by decreasing the increase in the internal resistance of the battery.

Title: Controller
Inventor: NAMIE MASAKI
IPC: G05B13/02
Filed: 1989-02-15
Abstract: PURPOSE:To identify the characteristics of a control subject and to set an optimum control factor in a PID arithmetic processing based on the result of the identification by using a two-position control element to produce a limit cycle and also adding a calculation part to calculate the characteristics of the control subject based on the vibration period and the amplitude of the limit cycle. CONSTITUTION:A two position control element 3 produces a limit cycle based on a deviation signal, and a calculation part 5 observes the vibration period and the amplitude of the limit cycle produced by the element 3. Therefore a limit cycle is produced by the element and the vibration period and the amplitude of the limit cycle are measured. As a result, the effects of noises can be prevented and furthermore the start point for measurement of the vibration period and the amplitude can be set after the effect of the controlled variable produced before generation of the limit cycle is eliminated. Thus it is not required to set the controlled variable before an auto-tuning action. As a result, both the manipulated variable (u) and the controlled variable (y) are more accurately observed and the characteristics of a control subject can be identified. Based on this identifying result, the control factor can be set in an optimum way in a PID arithmetic process.

Title: Method of and apparatus for generating power and/or heat from coal
Inventor: FURANTSU GIIRUTSU
IPC: F02C3/36
Filed: 1981-03-11
Abstract: A method and apparatus for power and/or heat generation from fuels. The fuel is fed to a combustion chamber and a pressurized gaseous oxidizing agent is fed to the combustion chamber to fire the fuel in a fluidized bed. The smoke gases coming from the fluidized bed are cooled, purified in a purifier such as an electrostatic filter, reheated in a heat exchanger immersed into the fluidized bed and fed to the gas turbine. The exhaust gas from the gas turbine is fed to a recuperator for gaining the residual thermal energy and is then released through a chimney. The cooling of the smoke gas can be achieved by adding compressed air to the smoke gas stream or by introduction, e.g. into the upper half of the combustion chamber of a water or steam operated heat exchanger.

IPC: H04L27/18
Filed: 1986-02-20
Abstract: PURPOSE:To attain the digital transmission at high speed by using a signal as a transmission signal having information sent at a phase difference between the first half and the latter half parts of time slots part by a prescribed time slot number. CONSTITUTION:For example, the phase difference between the 2nd time slot and the (n-2)th time slot is theta and the location of phase transition is in the same location in respective time slot.

Title: Air fuel ratio sensor
Inventor: YAMADA TETSUSYO
IPC: G01N27/407
Filed: 1985-02-25
Abstract: PURPOSE:To control an air fuel ratio over a wide range extending from the lean area to the rich area by a simple arrangement by combining an oxygen pumping element and an oxygen gas sensing element. CONSTITUTION:In the lean state, negative potential is applied to an inner electrode and a positive potential is applied to an outer potential that is not contacted with a gas diffusion part 4 of a pair of electrodes constituting an oxygen pumping element 2 together with a solid-state electrolyte 1. Oxygen ions are then moved in the electrolyte 1 from inner to outer electrodes to pump out the oxygen gas in the diffusion part 4. The oxygen partial pressure of the detected gas in the diffusion part 4 formed by a porous body 7 to limit the flow of measured gas is changed and detected by an oxygen gas detection element 2 provided to the diffusion part 4 as the resistance value. When the current supplied to the element is controlled so that the resistance value will be constant, the oxygen gas content ratio is determined substantially linearly from the current volume. In such a way, for the rich state, the air fuel ratio can be controlled in the feedback fashion on the basis of the wide range of measurement from the lean state to the rich state by a simplified constitution requiring no reference oxygen source.
