Title: Method of selecting ball outer diameter of ball spline
Inventor: ISHIDA HIDEO
IPC: G01B21/10
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To enhance the measurement precision of play of a ball spline by measuring the play, determining the correction quantity for correcting the clearance between a ball and a spline groove, determining the outer diameter of the ball, and selecting the ball. SOLUTION: A reference ball 10 having an outer diameter smaller than that of a ball 43 actually interposed is prepared, and prior to a ball spline 40, the play AO which is the distance of an outer spline groove 42 to an inner spline groove 41 is measured in the state where the reference ball 10 is interposed between both the spline grooves 41, 42. The correction quantity for correcting the clearance by the fluctuation of contact angle is determined on the basis of the outer diameter in non-load to determine the outer diameter of the ball 43. In the assembling of a pulley, various balls 43 with different outer diameters are preliminarily prepared, and the ball 43 having an outer diameter close to the calculated outer diameter is selected by performing the calculation and correction of the play, and assembled to the ball spline 40 to suppress the error of the play.

Filed: 1990-03-19
Abstract: PURPOSE:To attain automatic changeover of its own mode depending whether the opposite equipment to be connected is in the DTE mode or the DCE mode by using 1st and 2nd switches. CONSTITUTION:Voltage automatic detection circuits 15, 16 detect it that a voltage is impressed to an SD line 11 or an RD line 12, and a discrimination circuit 18 for the DTE(data terminal equipment) mode and the DCE (data line terminator) mode decides whether a relay circuit 19 is turned on or off in response to the result of detection. A switch A is thrown to the position of an a-contact when the relay circuit 19 is not energized to set itself to the DTE mode and the switch A is thrown to the position of a b-contact when the relay circuit 19 is energized to set itself to the DCE mode. Thus, after the mode is decided to be in the DTE or the DCE mode, a connection discrimination circuit 17 energizes a relay circuit 20 to open the switch B thereby connecting the line. Thus, the own mode is selected automatically depending whether the connected opposite equipment is in the DTE mode or the DCE mode.

IPC: F24F13/14
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent an occurrence of dirt at the time of a horizontal blowoff and a short cycle at the time of a downward blowoff by mounting wind direction control means which extends in a longitudinal direction of an air outlet and controls a blowoff direction of air-conditioning air in the air outlet. SOLUTION: At both ends of a wind direction control plate disposed in the inside of a blowoff nozzle for blowing off air-conditioning air into a room, movable parts 14 are provided as wind direction deflecting means. The movable parts 14 are constructed such that they can change an angle independent of a central part 13. The wind control plate is operated in such a manner that in a horizontal blowoff where the blowoff direction is in a direction along a ceiling surface, the movable parts 14 can change the blowoff direction at ends of the wind direction control plate to a direction away from the ceiling surface 5, while in a downward blowoff, the blowoff direction at ends of the wind direction control plate is changed to a direction away from a suction opening.  Due to such a construction, air low 7 at both ends of the wind direction control plate can be blown off more downwardly than air flow 6 at the central portion of the wind direction control plate so that air flow 7 is prevented from being induced into a negative pressure region defined between a blownoff air flow and the ceiling surface thus preventing an occurrence of dirt on the ceiling surface.
