Title: Iron-base metal sintering method
Inventor: MIYANO MASAHARU
IPC: B22F1/00
Filed: 1979-12-22
Abstract: PURPOSE: To manufacture an iron-base sintered metal with superior mechanical strength by adding a small amount of ferric oxide fine powder to raw material cast iron powder followed by compacting and sintering in a nonoxidizing atmosphere.  
     CONSTITUTION: Cast iron cutting chips are pulverized, adjusted to a suitable grain size, and mixed with 0.5W<2wt% Fe 2 O 3  powder of ≤325 mesh. This mixed powder is filled into a metal mold and compacted to form a green compact. The compact is then sintered by heating at 1,000W1,200°C in a reducing or inert atmosphere for 10W60min according to the form and size of the compact. Thus, graphite fine powder stuck to the cast iron powder and the Fe 2 O 3  fine powder are allowed to react rapidly and effectively, whereby the Fe 2 O 3  are reduced to active Fe atoms to accelerate sintering and enhance the mechanical strength of the resulting sintered body.

Abstract: PURPOSE:To prevent generation of yellow spots by sequentially forming an intermediate coat and a phosphor coat consisting of a transparent conductive coat and metallic phosphate on the inner surface of a glass bulb. CONSTITUTION:A trasparent conductive coat 2 consisting of a thin film of tin oxide is formed by heating and evaporating an organic tin compound to which a small amount of organic antimony compound is added and coating the inner surface of a glass tube 1 with it. An intermediate coat 3 is formed by applying the suspension of metallic phosphate to the transparent conductive coat 2 and drying the coat. Then after the suspension obtained by diffusing a phosphor in an organic binder solution is applied to the intermediate coat 3 and is dried, a phosphor coat 4 is formed by evaporating the organic binder by heating. If metallic phosphate is used as the intermediate coat 3, coating can be reduced and a yellow spots generation rate prevention effect can be obtained as compared with the coat that uses the conventional metal oxide.

Abstract: PURPOSE:To eliminate a low frequency noise component efficiently such as 1/f noise by retarding a CCD output signal with 2 kinds of delay lines and calculating the result with a retarded signal. CONSTITUTION:A delay time tau1 of a 1st delay line 3 is selected to be a length when an end point of a field through period 8 of a charge coupling element(CCD) output signal and an end point of a signal output period 9 of an output signal of the 1st delay circuit are coincident, Moreover, a delay time tau2 of a 2nd delay line 4 is selected to be a length when an end point of a field through period 8 of a charge coupling element(CCD) output signal and an end point of a field through period 10 of an output signal of the 2nd delay circuit are coincident. Then an arithmetic circuit 5 subtracts a half of the CCD output signal and the 2nd delay signal from the 1st delay signal and a gate circuit 6 extracts only a signal for periods t1-t2 when the field through period 8 the signal output period 9 and the field through period 10 are overlapped and the result is converted into a continuous video signal by a low pass filter 7 finally.
