摘要： Disclosed is a process for preparing a beta-diketone compound such as 2,6-dimethyl-3,5-heptanedione, which comprises reacting an ester compound such as an alkyl isobutyrate with a ketone compound such as 3-methylbutanone in the presence of an alkali metal alkoxide as a catalyst. The process comprises a step 1 in which an ester compound CR R R COOQ is reacted with a ketone compound CR R R COCH2R7 using an alkali metal alkoxide catalyst to give a beta-diketone compound CR R R COCHR R R . (In the formulae, R is hydrogen or an alkyl group of 1 to 4 carbon atoms while others are each independently hydrogen or an alkyl group of 1 to 3 carbon atoms, and at least one of R to R is hydrogen.)

摘要： A threaded joint for steel pipes constituted by a pin having male threads and a box having female threads is improved with respect to ease of insertion of the pin and galling resistance of the threaded portions. The stabbing flanks of the threads in a complete thread portion of one of the pin and box has a two-step stabbing shape having a chamfer. The two-step stabbing shape has a stabbing flank angle a of 5 - 45° and a chamfer angle ß of 20 - 60°. The ratio h/H of the chamfer height h to the thread height H of the pin is 0.25 - 0.50, or the ratio of the cross-sectional area of the chamfered portion to the overall cross-sectional area of the stabbing flank is made at least a value corresponding to a chamfer height ratio h/H of 0.25 and at most a value corresponding to a chamfer height ratio of 0.50.

摘要： PROBLEM TO BE SOLVED: To obtain a D/A converter which is inexpensive and has high reliability and high accuracy by using a switched capacitor technology for the weighting of analog voltage that corresponds to each digital input and serially connecting plural weighting circuits. SOLUTION: Given voltage is accurately divided equally by using a switched capacitor technology. For instance, relating to a 4-bit D/A converter, changeover switches S1 to S8 for a voltage equal dividing circuit are interlocked and periodically switched, and K1 and K2 , K3 and K4 , and K5 and K6 are respectively interlocked and switched among break before make changeover switches K1 to K7 which correspond to each digital input bit. Electric potential of input voltage of the next weighting circuit is changed by increasing and reducing the potential of weighted output voltage of each analog voltage weighting circuit which is weighted to each part in accordance with a digital input code, and addition of each weighted analog voltage is performed.

摘要： PROBLEM TO BE SOLVED: To register, hold, and repeatedly use setting data on macrodefinitions, etc., corresponding to software and to facilitate operation and enables even vocal operation by writing inputted key data in a work area of an internal nonvolatile memory, etc., and reading key data out with a call key and sending it out to a computer main body. SOLUTION: Registered data are inputted to a CPU 12 and a work area of a RAM 14b generally from an attached keyboard 32 and held in the internal nonvolatile memory 14c or an external storage device such as an IC memory card. Then the data is called optionally through the CPU 12 and the work area of the RAM 14b, sent out of the computer main body 30, and usable. Data which can be used as the registered data are data of a microphone, RS-232C, a magnetic card, a bar code read, an optical communication device, etc., in addition to the key data, and the respective peripheral devices are connected to respective ports, etc., of the CPU 12 when necessary.

摘要： PROBLEM TO BE SOLVED: To provide a calcium oxide dispersion liquid in which a calcium oxide having a small particle diameter and high purity is homogeneously dispersed, and its manufacturing method. SOLUTION: The calcium oxide dispersion liquid contains calcium oxide fine particles having a median particle diameter (volume basis) of 1-200 nm and a maximum particle diameter of 10-1,000 nm, and an organic dispersion medium. In the manufacturing method of the calcium oxide dispersion liquid, the calcium oxide dispersion liquid is produced by filling the calcium oxide fine particles, the organic dispersion medium and beads of 5 to 200 μm in diameter into a container and stirring these materials.
