Title: Cooling roll for producing amorphous alloy light-gauge strip
Inventor: TACHIKAWA MASAAKI
IPC: B22D11/06
Filed: 1982-09-02
Abstract: PURPOSE:To provide a cooling roll for producing an amorphous alloy light- gauge strip which prevents the decrease in the water pressure in a cooling water flow passage between an inside roll of a narrow width formed integrally to the cooling role by shrinkage fit and a steel flange enclosing the same and can supply steadily the cooling water by providing fins for preventing the rotation of the cooling water to said flow passage. CONSTITUTION:A cooling roll 33 is formed wider than an inside roll 34 and is constituted integrally by shrinkage fit to the roll 34. The roll 33 is engraved internally with a cooling groove 39 for forming a cooling water passage 35'. Plural sheets of fins 40 for preventing the rotation of the cooling water are secured to the roll 34 in the cooling flow passage 35'' on the outlet side of a steel flange 32. The thermal expansion of the roll 33 is suppressed by the above-mentioned constitution. The ratio in suppressing the thermal expansion in this case is generally about the thickness between the cooling rolls/the radius of the inside roll, thus decreasing to about 1/50 of the ratio in an ordinary case. The amorphous alloy light-gauge strip is thus produced with good accuracy and stability.

Title: Random access memory
Inventor: SATOU TAKASHI
IPC: G11C11/41
Filed: 1984-07-25
Abstract: PURPOSE:To obtain a random access memory which offers two different ways of application to a user by incorporating a timing logical circuit to select two types of writing timing. CONSTITUTION:The precharging action is through with the gate capacities of FETQ5 and Q6 when a precharging pulse signal phi1 is changed to 0 from 1. Based on this fall edge, a reference pulse signal phi10 is applied to an FETQ5 with a delay equivalent to a prescribed time T0. In this case, if a pulse signal phi2 is already set at 1, the FETQ5 is turned off since an FETQ1 is turned on. Thus it is improssible to turn on an FETQ3 although the signal phi10 is set at 1. Therefore an output pulse phi3 is set an inactive level. While the pulse phi3 is set at an active level in case the signal phi2 is set at 1 with a delay.

Abstract: PURPOSE:To perform an automatic storing of a large amount of ices having a high transparency and a high purity in an ice storing box by a method wherein an ice making process is started from an upper surface of the ice making pan and non-freezed water containing gaseous component or some impurities discharged downwardly is separated from it. CONSTITUTION:A predetermined amount of water in a water supplying tank 36 is supplied into an ice making pan 16 through an ice storing pan 39 and through a water supplying pipe 41. One-way freezing operation is carried out from a water surface to a lower part under a thermal insulating action provided by a thermal insulation tank 9, a heating operation with a heater 15 from a lower surface and a cold air within a freezing chamber 7. Gaseous components or impurites in the water are discharged into the lower water and the ice crystals are formed. Then, as the first supporting shaft driving device 23 is operated at such a time as one in which the ices show a proper thickness, the ice making pan 16 is reversed in its rotation to remove ices, resulting in that the ices are dropped onto a water drain pan. Non- freezed water containing gaseous components and having a high degree of concentration of impurities is separated and its water is drained and the water is discharged through the water discharging pipe. The water drain pan having some ices therein is rotated in a reverse direction by a driving device for the second supporting shaft 22 and the ices having a high degree of transparency and high degree of purity are dropped and stored into an ice storing box.
