Abstract: PURPOSE: To lighten a load applied on a bearing and thus to improve durability of the bearing by a construction wherein each impeller of three eccentric liquid- sealed pumps is supported with a common rotary shaft, and the impellers are provided counterwise each other eccentrically.  
     CONSTITUTION: A single-suction pump 2 is provided on both ends of a common rotary shaft 1, and a double-suction pump 3 is provided at the center. An impeller of said suction pump 2 and an impeller of the double-suction pump 3 are set counterwise each other eccentrically. According to this constitution, the direction of a radial thrust load applied on the rotary shaft 1 from the single-suction pump 2 and the direction of a radial thrust load applied on the rotary shaft 1 from the double- suction pump 3 become counter each other, therefore a load on a bearing is lightened, and thus a durability of the bearing can be improved.

Title: Free settling type liquid carbon dioxide neritic feeding system
Inventor: AYA TAKEO
IPC: C01B32/50
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To allow low-temp. carbon dioxide to freely settle down to a storage depth and to embody deep-see storage and a dissolution method at a low cost of the same extent by releasing the low-temp. carbon dioxide in the foot of large liquid bubbles into the shallow sea based on the notice of the fact that the low-temp. liquid carbon dioxide is heavier than the seawater even in a shallow sea while the deep-sea storage method of carbon dioxide is a promising technique for remedy for the global warming effect making it possible to expect that the isolation period of the carbon dioxide from the atm.  attains >=2000 yours of the perpendicular circulation period in the seawater and this method is heretofore considered disadvantageous in comparison with the dissolution method of improving the carbon dioxide to a middle layer in that the feeding of the liquid carbon dioxide deeper than 3500 m at which the storage thereof is possible, is mandatory. SOLUTION: When the low-temp. carbon dioxide of <=-26 deg.C is released in the form of the large liquid bubbles 4 of >=0.7 m in diameter into the shallow sea of a depth 500 to 750 m<3> , the large liquid bubbles covered by an ice layer of a thickness of >=5 cm are increased in the temp. by the heat received from the seawater as the bubbles settle. The low temp. for maintaing the settling power is held until the carbon dioxide reaches the depth 2750 m which is of the same density as the density of the seawater in a thermally equil. state, and finally, the carbon dioxide settles freely down to the storage possible depth.

Abstract: PURPOSE:To simplify the constitution of a column decoder by including in the said decoder a pre-decoder which outputs a timing signal to select from plural data lines. CONSTITUTION:When the output of a unit column decoder UDCR is made H by addresses a1-a(m-1), timing-signal-transmitting Q7 and Q8 that turn on with an inversed precharge signal PHIp are on as they are. And H-level timing signals PHIy0 and PHIy1 outputted by the pre-decoder PDCR in response to an address a0 and inversed a0 are pulled up through the Q7 or Q8, so that the Q9-Q12 and Q13-Q16 of a column switch c-SW1 that connects multiple data lines and inversed D with complementary data lines CD0 and CD1 and inversed CD0 and CD1 are controlled. In such way as the above, the number of unit circuits constituting the column decoder is decreased and hence the said decoder's constitution is simplified.

Title: Printing device, interruption request processing method and storage medium
Inventor: SAKAI MASAHIKO
IPC: G06F9/46
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a printing device for preventing a specified task, especially a task related to a data reception processing from occupying CPU, and to provide an interruption request processing method and a storage medium. SOLUTION: When printing information from a host computer 1 is received in a state where the priority of an interruption request is set like 'timer interruption > data reception interruption > vertical synchronizing signal interruption', the number of starting times (number of interruption times) on the task started with a strobe signal on an interface as a trigger is counted for prescribed time. It is judged whether the value of an interruption times number counter exceeds a prescribed value or not. When the value of the interruption times number counter exceeds the prescribed number, the setting of priority is changed by exchanging a data reception interruption request and a vertical synchronizing signal interruption request in an interruption control circuit 13.

Abstract: PURPOSE: To obtain a vessel which is superior in the uniformity of mechanical properties and is provided with good ductility and toughness by deep-drawing a steel plate of tensile strength 50 to 65 kg/mm 2  containing a small amount of Nb and annealing this in the temperature region of the Ac 1  to Ac 3  transformation point of that steel.  
     CONSTITUTION: A steel plate of tensile strength 50 to 65 kg/mm 2  containing 0.01% or over and up to 0.03%, preferably 0.015 to 0.025% of Nb based on weight is deep-drawn to be formed to a vessel of a desired shape. Next, this is annealed in the suitable temperature region (about 750 to 800°C) between Ac 1  to Ac 3  transformation points. Such treatment causes the strengths (hardnesses) of the various sections of the vessel having increased in variations owing to fabrication to approach rapidly to a fixed value. In addition, the vessel of less strength degradation as compared to blank steel plate may be obtained and its ductility and toughness become better as well.
