IPC: F28F1/00
Filed: 1982-05-21
Abstract: PURPOSE:To improve transfer capacity of condensed heat by increasing the sectional area of a condenser tube which is nearly vartical, and by decreasing the condensed rate of liquid resident in the top part and at the lower end of the tube, by leaving both ends of a horizontally circular tube in the circular form, by forming a condenser tube by flattening the sectional area of the center part, and by fixing both ends of a condenser tube to a tube plate, with the longitudinal direction of the flattened sectiolnal area being faced to the flowing direction of the steam. CONSTITUTION:Both end parts 11, 11 of a circular tube are left in the circular form at least in the necessary length A to fix them to a tube plate, and the sectional area of the center part 12 of the tube is flattened. The flattened section of the center part 12 is formed so as to be an oval form, having the same wet surface as of the circular tube, or the oval form of which longer longitudinal ends are formed in sharp ends by a method of rolling or a press work. Both ends of the condenser tube 10 having the above-mentioned sectional areas are fixed to the tube plate with their sectional longer axises being faced to the steam flow, in the part where the velocity of the steam flow is dominant. On the other hand, they are fitted to the tube plate to face to the vertical direction in the part where gravity is dominant. In such a manner, the sectiolnal area can be brought near a blade form, to enalbe to restrain the separation point of a boundary layer, or to delay the occurence of it, to increase the vertical surface area which is effective to transfer heat, as a result, heat transfer capacity of condensed heat can be improved.

Abstract: PURPOSE: To remove the foreign matter deposited on surfaces and to improve the life and cost of forming dies by replacing a forming material with a cleaning material in midway and heating and forming this material in a state below a specific viscosity at the time of holding a forming material between a pair of upper and lower forming dies and heating, softening and press forming the forming material. CONSTITUTION: A glass preform is placed on the lower forming die 20 and the upper forming die 10 is inserted into a drum mold 25 down to a level at which this die does not come into contact with the preform. The upper and lower forming dies 10 and 20 are held in a gaseous nitrogen charging atmosphere and the preform is heated. The upper forming die 10 is lowered by a lifting cylinder rod 27 at the point of the time when the prescribed viscosity is attained, by which the preform is press-formed. The gas is vented after cooling and the formed material is taken out. The fine foreign matter deposits increasingly on the surfaces of the upper and lower forming dies 10 and 20 when the forming is repeated.  The forming material is replaced with the cleaning material which attains the viscosity lower than the viscosity of the forming material at approximately the same heating temp. as the heating temp. of the forming material at the point of this time. The cleaning material is heated and formed until the lower viscosity state of <=10<8.0> poises is attained, by which the deposited fine foreign matter 10F is taken into the cleaning material CG and the forming dies 10, 20 are cleaned.

CONSTITUTION:A substrate 1 is rested in a vacuum container 11, then, the vacuum container 11 is evacuated down to the degree of vacuum as low as 10<-3>Torr, the temperature of a heater 13 provided for the top and the bottom in such a way as to hold the substrate 1 is regulated to be of a temperature equal to or more than 500 deg.C thereafter, for example, 600 deg.C. On the other hand, DC voltage of 50V is applied by a power supply 14 so that No.1 electrode 2 on the substrate side shall be negative, and No.2 electrode 6 shall be positive, and the substrate 1 is thereby heated for two hours in a thermal environment. Fluorine atoms take on the character of negative loading, this thereby permits No.2 electrode 6 on No.2 insulating layer 5 side to be of negative polarity, which situation allows the fluorine atoms to remain within a membrane made of ZnS of the luminous base material in a luminous layer 4 so that they are not deposited onto an interface interspaced with No.2 insulating layer 5, thereby preventing No.2 insulating layer 5 from being peeled off.

Title: Optical recording medium
Inventor: SUZUKI KAZUTOMI
IPC: G11B11/10
Filed: 1990-04-04
Abstract: PURPOSE:To obtain an optical recording medium with satisfactory C/N and satisfactory durability by forming a metal reflection layer by AgAl alloy in the optical recording medium equipped with the metal reflection layer. CONSTITUTION:The metal reflection layer is composed of the AgAl alloy including Al in Ag. In such a case, there is tendency that a reflection factor is lowered and the C/N is lowered when the additive amount of the Al in the AgAl alloy is increased. On the other hand, when the additive amount is too much reduced, an effect to be exerted upon the durability is made small. From this point of view, as the additive amount of the Al, 3-60 atom % is preferable and especially, 10-40 atom % is further preferable. Moreover, by including any specified element into this AgAl alloy, recording sensitivity can be improved, namely, heat conductivity can be lowered and durability can be improved.
