Title: Medium density iron powder for powder matallurgy and its production
Inventor: ENDOU KAZUYA
IPC: B22F1/00
Filed: 1979-05-01
Abstract: PURPOSE: To obtain the captioned iron powder at low cost which excels in powder characteristics, green compact properties and machinability when made into sintered body, by mixing atomized iron powder containing a specified amount of S and roughly reduced iron powder by specified ratio, and completely reducing at spedified temperature, then crushing to specified grain size.  
     CONSTITUTION: A mixture powder of incompletely reduced iron powder 25W75% and incompletely reduced atomized iron powder containing 0.095W2.1% S is completely reduced in reducing atmosphere in the temperature range of 750W1,000°C by an ordinary method, and is crushed until the content of powder of 100 mesh or under is 80% or more. Part of atomized iron powder containing S metallurgically binds with roughly reduced iron powder to distribute S uniformly, and zinc stearate of which apparent density is 2.4W2.95g/cm 3  is added by 1%, and this mixture is formed and compressed at a pressure of 5kg/cm 2  to obtain an iron powder of 6.6W 6.85g/cm 3  of green compact density and 0.05W0.3% S content. Thus, the captioned iron powder excelling in green compact properties and machinability when made into sintered body is obtained at a low cost and at a high yield.

Title: Low-noise television system
Inventor: SUGIMORI YOSHIO
IPC: H04N7/015
Filed: 1987-03-06
Abstract: PURPOSE:To suppress a noise preventing overmodulation from being generated, by transmitting a luminance signal after applying preemphasis on the high frequency area of the luminance signal corresponding to the amplitude of a low frequency component. CONSTITUTION:A signal inputted from a color camera, etc., is inputted to a matrix circuit 1, and the luminance signal Y is generated, and is separated to three systems. In first system, first signal is obtained by processing the signal Y with a flat high frequency area. In second system, second signal is obtained by processing the signal Y with a pre-emphasis frequency characteristic by which a gain is raised according to the increase of a frequency at the high frequency area. In third system, a mixing ratio K of the first signal to the second signal is calculated by a K component generation circuit 8 based on the low frequency component of the signal Y. And the first signal and the second signal are synthesized in a form of the third signal=(first signal)X(1-K)+(second signal)XK, then, the third signal is generated, and broadcasting is performed setting the third signal as the luminance signal.

Title: Instrument for detecting slag foaming and slagging condition in refining furnace
IPC: C21C5/46
Filed: 1992-03-11
Abstract: PURPOSE:To precisely detect slagging condition and slag foaming level by observing variation of vibrating condition received by an auxiliary lance according to the slagging condition while giving forced vibration to the auxiliary lance. CONSTITUTION:By a hydraulic vibration generator 5 fitted on one end of the auxiliary lance 3 inserted in a converter 1, the forced vibration is given to the auxiliary lance 3. Spitting generated at the time of starting the blowing gives intermittent vibration having amplitude different from that of forced vibration to the auxiliary lance 3. This intermittent vibration is measured with a vibration detector 6, extracted with a filter 9, a converting device 10 and an arithmetic device 11 through an amplifier 8, and by observing it time sequentially, the progressing condition of the slagging can be grasped. As the foaming of the slag 14 progresses, the vibration of the auxiliary lance 3 is attenuated by the viscosity of the slag 14. Frequency of the forced vibration is separated and the change in the vibration except the forced vibration is calculated with the arithmetic device 11 to detect the slag foaming level.

Title: Water overflow preventer for washer
Inventor: IRIYAMA TAKUJI
IPC: D06F33/02
Filed: 1978-05-04
Abstract: PURPOSE: To prevent the overflow of water even when a first pressure switch and a feed water solenoid valve are defective, by providing a second pressure switch and a second air trap and appropriately setting the trip point and set point of the second pressure switch.  
     CONSTITUTION: When the first pressure switch 19 and the feed water solenoid valve are defective and a first trip HT1 is higher than a prescribed water level and water is continuously supplied, this state is detected by a second trip HT2 of the second pressure switch 20 and the second air trap 15 and a contact of the second pressure switch 20 is shifted to an NO side. A solenoid valve for opening a cock is thereby energized to drain the water from a vessel 13 to a second reset point HR2. When the level of the water has fallen below a first reset point HR1 and a first air trap 14, the solenoid valve for opening the cock is de-energized. Therefore, the level of the water repeatedly moves up and down between the second trip point HT2 and the second reset point HR2 so that the water is prevented from overflowing.

Abstract: An explosive powder charge operated tool for driving nails includes a housing with a muzzle part mounted in and projecting axially outwardly from the housing. By moving the muzzle part rearwardly into the housing, the tool is in the ready-to-fire condition. A magazine is supported at one end within the muzzle part and extends generally radially outwardly from it. A slide in the magazine feeds individual nails in a nail strip into the bore in muzzle part into position to be driven by a piston located within the housing. When all of the nails in the strip have been driven from the tool, one end of the strip projects into the muzzle bore. A stop shoulder on the one end of the strip faces toward an end face on the housing and contacts the end face when the muzzle part is pressed into the housing, preventing the placement of the tool in the ready-to-fire condition.
