Title: Method for ingot-making of chromium and chromium alloy
Inventor: NISHI SEIJI
IPC: B22D21/02
Filed: 1989-03-13
Abstract: PURPOSE:To obtain a cast ingot of Cr (alloy) at good yield by using a metallic mold for ingot-making having the specific value of mold ratio at the time of casting molten Cr (alloy) produced under reduced pressure inert gas atmosphere. CONSTITUTION:The mold ratio is the ratio of wall part vol. in the metallic mold to the ingot part vol. in the metallic mold for ingot-making. At the time of casting the molten Cr under reduced pressure inert gas atmosphere, by using the metallic mold for ingot-making having 0.4 - 1.1 mold ratio, heat conduction at the time of casting, particularly, at the initial stage of pouring is executed desirably and the inner cracking 2 in the Cr cast ingot 1 after ingot-making is prevented. In the case the mold ratio is less than 0.4, the preventing effect of the inner cracking in the cast ingot is obtd., but as the temp. of molten metal is high, erosion of the metal mold is developed and mingled as impurity and it is not desirable. In the case the mold ratio exceeds 1.1, as temp. difference between the inner part and the surface in the cast ingot is made large and the inner cracking is developed, so the mold ratio is made to 0.4 - 1.1. By this method, vaporization of Cr is suppressed under the reduced pressure inert atmosphere and the oxidation is prevented and the cast ingot can be obtd. at good yield.

Abstract: PROBLEM TO BE SOLVED: To efficiently transmit a voice signal and also to enhance articulation of a voice. SOLUTION: A signal Smc from a microphone 12 is made to be a signal Sn by eliminating the higher frequency components and the lower frequency components of the signal in a variable part 16 which considering the frequency band of a voice to be sounded by human beings. A control part 30 generates a signal Csw based on a signal MD indicating that the signal Smc is being outputted and a changeover part 20 selects the signal Sn to supply it to an A/D conversion part 22 as a signal Sta. A conversion part 22 converts the signal Sta into a digital signal Dta by lowering a sampling frequency and the number of quantizations based on a signal Caa to transmit it to a transmitting part 24, which generates a transmission signal Ta based on the signal Dta and information HD indicating the sampling frequency and the number of quantizations.  The articulation of the voice is enhanced by preventing noise of higher frequencies while eliminating the higher frequency components in the variable part 16 and by preventing the voice from becoming mimesis while eliminating the lower frequency components in the part 16. Moreover, since the data quantity of the signal Dta is small, the voice signal is efficiently transmitted.

CONSTITUTION:Three or more of low concentration semiconductor layers 2, 4, and 6 of one conductivity type are laminated on a semi-insulating semiconductor substrate 1, and parts in the vicinity of surfaces in their odd numbered 2 and 6 specific regions are formed in high concentration regions 3 and 7 of reverse conductivity type. Parts in the vicinity of surfaces in their even numbered 4 specific region are formed in a high concentration region which is of one conductivity type and formed to be superposed on part of the odd numbered high concentration regions 3 and 7. Further, said odd numbered and even numbered high concentration regions are connected with respective high concentration regions 9 and 10 independently so that they are identical in their conductivity types with each other. Since transit time of carriers is thus determined from a thickness of each one of low concentration semiconductor layers, a high-speed response characteristic is obtained. On the other hand, since quantum efficiency is determined from the total thickness formed by adding thicknesses of respective divided high absorptive layers, a high quantum efficiency characteristic can be realized in addition.
