Title: Sense amplifier circuit
Inventor: SUGIMOTO MASUNORI
IPC: G11C11/34
Filed: 1984-03-13
Abstract: PURPOSE:To obtain a sense amplifier circuit of current detection type free from variance of resistance by detecting and amplifying the current difference without conversion into the potential difference through a resistance. CONSTITUTION:When a current added to an input terminal 11 is larger than that added to an input terminal 12, a potential of a connecting point 18 changes more quickly than that of a connecting point 19. As a result, an MOSFET2 is soon conducted, a potential of an output terminal 9 drops, an MOSFET6 is interrupted and charging of a capacity 17 is stopped. Consequently, the rising of the potential of the connecting point 19 is also stopped. Thus a potential of an output terminal 10 is left as VDD, the potential of the output terminal 9 becomes approximate to VSS, and therefore it can be detected that the current added to the input terminal 12 is larger than that added to the input terminal 11. In the same manner, the potential of the output terminal 9 and that of the output terminal 10 become approximate to the VDD and VSS, respectively.

Title: Production of metallic calcium
Inventor: MORI TSUTAE
IPC: C22B26/20
Filed: 1984-03-13
Abstract: PURPOSE:To enable production of Ca having much higher purity by subjecting again the residues made after CaO is subjected to pressure reduction thermal reduction by Al and high-purity Ca is won to the pressure reduction and thermal reduction by Al. CONSTITUTION:Al is added and mixed to and with CaO and the mixture composed thereof is put into a retort where the pressure is reduced to <=10<-3>Torr and the CaO is heated and is thus reduced to Ca. The Ca vapor made therefrom is then cooled and solidified to manufacture metallic Ca. MgO is contained in CaO as a raw material in this case and since Mg has the higher vapor pressure than Ca, MgO is preferentially reduced to Mg and enters the metallic Ca formed by entering the Ca vapor, thereby decreasing the purity thereof. The residues remaining after such reaction consist essentially of 3CaO.Al2O3 contg. substantially no MgO and therefore such residues are again subjected as a raw material to the pressure reduction and thermal reduction by Al, by which the metallic Ca of high purity contg. extremely little Mg is obtd.

Filed: 1982-03-29
Abstract: PURPOSE:To improve the performance of a compressor by securing oiling to the compressor while properly setting the ratio of the total outlet area of an oil separating part toward the compressor volume to the theoretical volume of the compressor. CONSTITUTION:The flow rate of a gas mixture is determined by the theoretical volume Vth of a compressor and the total outlet area St when the gas mixture is discharged. Accordingly, when the ratio of the values Vth to St, i.e., Vth/St is assumed K, it is possible to evaluate the separation efficiency of oil by changing the value of K, i.e., can be estimated using the height (h) of oil stored in an oil reservoir 24 within a chamber 11 from the bottom of the oil. The normally applied maximum number of revolutions of the compressor of a car air conditioning device is generally taken to be about 6,000rpm, so that K<=0.4 is required to be satisfied in order to secure the height (h) of the oil level higher than necessary, up to said number of revolutions.
