Title: Method for decision of rate of hardening of mold
Inventor: NAKAZAWA TETSUO
IPC: B22C1/00
Filed: 1980-06-13
Abstract: PURPOSE:To make accurate judgement of the rate of hardening of a mold possible by mounting a judging apparatus which contains therein a specific mold hardening condition judging sample into sand for mold, in the hardening of a mold by a CO2 method. CONSTITUTION:In mixing sodium silicate as a binder into molding sand, molding the sand to a mold, and blowing gaseous CO2 thereby quickly hardening the mold, a mold hardening judging apparatus 1 is mounted in a place where the gaseous CO2 is most difficult to pass. This apparatus contains a hardening condition judging sample 3 in a transparent case 2 of glass or the like and glass wool 4 in thelower part thereof. As the sample 3, an alkaline material such as sodium silicate or caustic soda which changes its pH by reacting with gaseous CO2 is mixed with silica sand,  glass beads or the like, and further an indicator such as phenolphthalein is added.  During hardening, the excess or shortage of the gaseous CO2 is surely judged from  the discoloration of the indicator, thus the failure of the mold owing to insufficient  hardening and the wasteful consumption of the gaseous CO2 owing to excessive  blowing of the gaseous CO2 are prevented.

Title: Light modulator
Inventor: KONDOU MITSUKAZU
IPC: G02F1/05
Filed: 1978-06-30
Abstract: PURPOSE: To obtain a stable light modulator causing small fluctuations in modulation efficiency with respect to changes in temperature and incident light wavelength, by decreasing the capacity of medium as approaching the entrance and exit ends of the light of light modulation medium and reducing the size of the electric field applied to the medium.  
     CONSTITUTION: A lithium tantalate crystal 11 is cut out in the vertical direction to X-axis, and is formed so as to transmit light in the direction of Y-axis. In the vicinity of light entrance and exit ends on the back side of the crystal 11 is disposed a dielectric thin film 18 of which thickness increases towards the entrance and exit ends, and a uniform, interdigital electrode 12 is placed over the entire surface of the crystal 11 thereon and earthed. When a voltage is applied to the electrode 12 from a signal generator 13, electric fields in the direction of X-axis are applied to the crystal 11 periodically in the  direction of Y-axis. Since the capacity of thin film 18 becomes smaller as going nearer to the ends, the electric field applied to the crystal 11 becomes smaller as approaching the ends. Thus, by providing the dielectric thin film 18, the electric field applied may be gradually decreased towards the ends of the crystal 11, so that fluctuation in modulation efficiency may be reduced.
