Abstract: PURPOSE: To provide a compact and light weight typewriter without a print magnet by a method wherein a reciprocally and rotationally driven motor is provided for the use with a drive for the rotational positioning of a print wheel and rotational movement of a print hammer and further, by a method wherein the reciprocal and rotational movement of a print hammer is driven by a motor shaft direction movement. CONSTITUTION: The rounded faces 12 and 13 are mounted on the legs 10 and 11 of a hammer 9 with which the disks are coupled. These disks are fitted to a motor shaft 7. Accordingly, the hammer is tightly held by both disks 14 and 15, and accurately driven by the axial movement of the motor shaft 7. When a print wheel 16 or the selected characters are on a print position to a platen 4, the electric conduction to the reciprocal to rotational movement of the motor 6 is changed so that the axial movement of the motor shaft 7 may be made to the arrow A direction. Further, the print hammer 9 is rotated around a hinge 8 and the character on the print position is printed. Thereafter, the motor shaft 7 is returned to the original position and the print hammer 9 is free from the print wheel 16 being in a position to newly start the rotational positioning movement.

Title: Failure detection system of ac circuit
Inventor: IWAMI EIJI
IPC: G01R31/12
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To identify various load currents from series arc by comparing a specified number of discontinuous periods and making a decision that series arc failure has occurred when the ratio thereof exceeds a predetermined value. SOLUTION: A current waveform detected by a current detecting means 3 is subjected to first differential through a first differential means 4 and then subjected to A/D conversion through the sampling means 5 in a constant period detecting means 2 to produce numeric data. A time detecting means 6 determines the duration of zero period numerically from that numeric data and an arc decision means 7 compares the longest one of a plurality of durations of zero period with the shortest one. When the ratio is substantially equal to 2 or above, a decision is made that series arc failure has occurred and a failure output signal is generated. When the duration of discontinuous period has a trend of monotone increase or decrease (not a random duration), the arc decision means 7 does not make a decision that series arc failure has occurred even if the ratio is substantially equal to 2 or above.

Title: Method for measuring bioactive component
Inventor: TAKADA MASATO
IPC: G01N33/531
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To remove the effects of binding protein coexistent in a bio-sample by adding an astringent in a range in which the activity of an object to be measured is not affected. SOLUTION: By exposing a bio-sample to an astringent, binding protein is dissociated from an object to be measured and is simultaneously irreversibly denatured. Sodium alum, potassium alum, etc., are used as the astringent, and the biomaterial is treated with an alum solution (pH 3-3.5) of 0.1 mM to 1 M, preferably 0.1 M. By using an appropriate amount of alcohol denaturant and hydrochloric acid dissociating agent together with the astringent in pretreatment, it becomes possible to improve the stability of the object to be measured, to shorten extraction time, and to eliminate the need for the use of centrifugal operation or a rebinding inhibitor. A surfactant such as urea, guanidine chloride and an organic solvent such as ethanol are used as the denaturant.  A competing measuring method using an antibody, binding protein or a receptor is used as a measuring method, and the pretreatment of a sample used in a sandwich method is used.
