Title: Electric cleaner
Inventor: HIRANO AKIHIRO
IPC: A47L9/04
Filed: 1988-06-08
Abstract: PURPOSE:To attain stable switching operation and to prevent a motor from being burned out by switching the motor when a prescribed time passes after the operation of a switch means with a delay circuit in case that the revolving direction of the motor to drive the motor is switched. CONSTITUTION:An agitator 7, which is revolved and driven by a motor 8 and abuts a stirring body on a cleaning surface, is provided in an absorbing room 6 and a switch means 16 for the revolving direction switch of the motor 8, which is operated with accompanying the forward and backward moving of the above mentioned absorber 2 for floor, is provided. When the proceeding direction of the absorber 2 for floor is changed and the switch means 16 is operated, the revolution switch of the motor 8 is not executed for the prescribed time by a delay circuit 21 and after a moving speed, which is obtained after the proceeding direction of the absorber for floor is switched, goes to be constant, the revolving direction of the agitator 7 is switched. Accordingly, operation such as the repeated forward and backward oscillation of the absorber for floor is erased and the absorber is smoothly moved. Then, for the switch of the motor, since the motor is revolved in a constant direction only during the time of this delay circuit 21 at least, the extremely stable switching operation can be executed.

Title: Instrument for measuring concentration of fissionable material
Inventor: HIGUCHI SHINICHI
IPC: G01N23/222
Filed: 1984-07-09
Abstract: PURPOSE:To measure background without requiring intricate procedures by segmenting the housing of a titled instrument into two chambers by a partition wall, contg. a neutron source and decelerating material into one chamber and contg. a sample into the other chamber. CONSTITUTION:The inside of the housing 1 of the measuring instrument is segmented to two large and small chambers by the partition wall 2. Water 4 which is the neutron decelerating material and the neutron source 5 are contained in the large chamber 3 and the sample 7 is contained in the small chamber 6. The thermal neutrons among the neutrons from the source 8 are absorbed to a thermal neutron absorbing plate 9 when the plate 9 is inserted into a guide 8 for inserting the thermal neutron absorbing plate and therefore only the neutrons which are too fast to generate nuclear fission arrive at the sample 7. A detector 10 in this state measures the emission neutrons of the sample and the neutrons which are released from the source 5 and are not decelerated to the thermal neutrons, i.e., background. The measured value relating only to the concn. of the fissionable material in the sample is obtd. by removing the plate 9, measuring the neutrons by the detector 10 and subtracting the background therefrom.

Filed: 1982-08-18
Abstract: PURPOSE:To refine steel having no hydrogen pickup at a low cost in an oxygen blowing device using double tuyeres by using the CO-contg. waste gas from a converter as a gas for protecting the tuyeres through the outside pipe of the double tuyeres. CONSTITUTION:Double tuyeres are used in the stage of oxygen blowing through the tuyeres under the surface of the molten steel in a bottom blown converter or the like, wherein oxygen is blown through the inside pipe and the CO-contg. waste gas produced from the converter as a protecting gas for cooling the tuyeres is drawn out without mixing with the outside air and is used through the outside pipe. CO decomposes to CO2 and C, and C enters the molten steel as carbon powder. The carbon powder reacts with the FeO formed by the oxygen ejected from the inside pipe of the tuyeres and reduces FeO to Fe. Since this reaction is endothermic, said gas plays the role of cooling the tuyeres and protecting the same.
