Title: Improvement of salt
Inventor: NAKAZONO SHUZO
IPC: A23L27/40
Filed: 1985-10-31
Abstract: PURPOSE:To obtain salt having reduced deliquescence and mild salty taste mitigating the characteristic salty and bitter taste of raw salt, by immersing raw salt in hot oil under reduced pressure and squeezing and removing the oil from the salt. CONSTITUTION:Raw salt is immersed in hot oil under reduced pressure and the oil is squeezed out and removed from the salt. The immersion treatment is carried out under slight evacuation condition (i.e. -10--20mmHg) for the first 30min or so and then in highly evacuated state (i.e. -740--750mmHg) for about 60min until the water-content of the salt reaches about 3-6%.

Title: Transmission circuit
Inventor: AGATA MASASHI
IPC: G11C11/407
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a signal transmission circuit operating at a high speed with low power consumption. SOLUTION: Gates of P-type 1st and 2nd transmission MOS transistors(TRs) 51, 52 are connected respectively to complementary input signal lines DIN, XDIN, sources are connected to a 1st power supply Vcc, and drains are connected respectively to complementary output signal lines DOUT, XDOUT. Then a 1st capacitive element 53 is arranged between a substrate and a gate of the 1st transmission MOS TR 51, and a 2nd capacitive element 54 is arranged between a substrate and a gate of the 1st transmission MOS TR 52. Thus, in the case of signal transmission, the substrate voltage of the transmission MOS TRs 51, 52 is changed statistically synchronously with the input signal and its threshold voltage is controlled to be high in the standby state and to be low in the active state.  Thus, a leakage current is suppressed in the standby state and the drain current is increased in the active state and the signal transmission speed is increased.

Title: Production of stannic oxide powder by dry process
Inventor: UCHIDA KENJI
IPC: C01G19/02
Filed: 1985-11-01
Abstract: PURPOSE:To readily produce fine stannic oxide powder only by a dry process, by heating metallic thin and stannic oxide in an inert atmosphere, leading the generated stannous oxide vapor to a low-temperature part and oxidizing the vapor. CONSTITUTION:Metallic tin is mixed with stannic oxide, preferably at about 80:10-50:50 weight ratio and the resultant mixture is put in a heat-resistant vessel, which is then heated in an inert atmosphere, e.g. nitrogen, which will not oxidize the tin in a heating furnace to form stannous oxide. The vapor of the formed stannous oxide vapor is led to a low-temperature part at a temperature about 50-500 deg.C lower than the atmosphere. The low-temperature part is a mixed gas atmosphere of nitrogen, helium, etc., with oxygen or air kept under an oxygen partial pressure sufficient to oxidize the tin and stannous oxide into stannic oxide. Thereby, the stannous oxide is decomposed into tin and stannic oxide and the tin is converted into stannic oxide.
