The zirconia material is compounded with castable refractories of the above-mentioned lance 1 so as to contain 30-67% ZrO2. Zirconia, zircon, etc., are used for the zirconia material. The generation of the erosion, crack, etc., in the above-mentioned castable refractories 11 by slag is prevented in this way and the life of the immersion type lance 1 is drastically prolonged.
Patent JP-H117664-A (JP)
Title: Production of optical record medium
Inventor: NONAKA TOSHINAKA
IPC: G11B7/26
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To decrease the residual stress in a formed film, to prevent peeling between layers due to changes in the residual stress when the residual stress in the film is large, and to prevent burst errors when an overwriting-type recording medium is repeatedly used, by disposing a substrate in a position not exposed to plasma when dielectric layers of the record medium are formed in sputtering film-forming processes. SOLUTION: As for the sputtering method to dispose a substrate in a position not exposed to plasma, a counter target-type magnetron sputtering method or a long-distance sputtering method are used. If a substrate is exposed to plasma, g-electrons, negative ions or Ar atoms collide with the substrate and sometimes give damages on the formed films to increase the residual stress. If the substrate is not exposed to plasma, damages on the formed films are significantly decreased. Thereby, dielectric layers with small residual stress can be easily formed and the obtd. layers show little changes with time and high durability against repetition.

Title: Temperature control device for air conditioner
Inventor: SUGIO TAKASHI
IPC: F24F11/02
Filed: 1984-08-01
Abstract: PURPOSE:To maintain the average room temperature at a temperature close to the set temperature regardless of the outside temperature by modifying the ON/ OFF point upon detecting the room temperature at the time of restarting the compressor. CONSTITUTION:After the stoppage (ts) of compressor under a cooling mode operation, the room temperature rises. When the temperature To at the time of restart is higher than Toff which is outputted from Tout as an OFF point set temperature, the output from a comparator circuit 19 becomes H, which is inputted to an LSI 15. The LSI 15 removes the temperature DELTAT which has earlier been set from the previous OFF point set temperature Toff' and outputs Toff- DELTAT from Tout 2 as a new Toff' and Ton+DELTAT is made a new ON point Ton. If To<=Ton again after the new mode has been assumed, operations to set a new Ton and Toff are repeated by adding or subtracting DELTAT. These operations maintain the average value of Ton and Toff to be always constant, and eventually the operation that can maintain the room temperature under Ton at the time of the compressor stoppage. For heating mode operations, the concept is same, although the upper and lower temperatures are reversed from those for the cooling mode operations.

Abstract: PURPOSE:To attain the restoration of a high frequency component of a signal without incurring complicated means or increase in the circuit scale by adopting the constitution such that a signal for a prescribed period before and after a noise part is sampled by a higher frequency than that for other period. CONSTITUTION:An audio signal lead to terminals 12, 13 is given to an A/D converter 14. The converter 14 uses a sampling clock SP outputted from a switch 15 to obtain a digital signal. The clock SP is obtained by using a control signal SEL obtained from a timing signal generating circuit 16 so as to select at a switch 15 sampling clocks SP1, SP2 given from the circuit 16. The frequencies Fsp1, Fsp2 of the clocks SP1, SP2 are selected, e.g., as Fsp2=1.5Fsp1. The signal SEL selects the clock SP2 for a prescribed period before and after the audio head switching and gives it to the converter 14.
