Title: Correction of pitch error
Inventor: HATSUTORI TAKEIWA
IPC: G05B19/404
Filed: 1980-12-30
Abstract: PURPOSE:To correct the pitch error by obtaining the value on a position detector for a plurality of standard length members and the unit elongation length of a screw due to temperature rise, in the captioned method for the pitch error generated because of the thermal expansion of a ball screw. CONSTITUTION:The transfer base 102 of a ball screw 101 shifts from a standard position OR between two standard length members 106a and 106b and stops when signals are transmitted because of the contact of the members 106a-106b of the tracer 104 installed on the transfer base 102. When the signal is transmitted, a pulse corder 105 reads each transfer amount. The elongation per length due to the temperature rise of the screw 101 can be obtained from the read value described the above according to a calculation equation. As the distance in which the ball screw 101 elongates can be obtained, positive or negative correction pulses are output in accordance with the elongation and transfer direction of the screw 101, when the cutter on the transfer base 102 transfers.

Title: Working method for printing wore guide member
Inventor: OTADA MASAMI
IPC: B24B31/00
Filed: 1987-07-28
Abstract: PURPOSE:To shorten the time required for the corner-rounding polishing of both end open peripheries of guide holes and for the finish polishing of the inner circumferential surfaces thereof, and to facilitate the cleaning after working by the combined action of both the fluid machining action due to a high-fluidity polishing liquid and the ultrasonic machining action due to an ultrasonic oscillator. CONSTITUTION:When a polishing liquid 6 is filled in the interior of upper and lower media cylinders 1 and upper and lower pistons 2, 3 are synchronously reciprocated up and down, the polishing liquid 6 inside the cylinders 1 is pressurized and flows upward or downward; when the polishing liquid 6 flows upward, it flows upward from below through the guide holes 7 in a guide member provided inside a jig 9, and when the polishing liquid 6 flows downward, it flows downward from above through the guide holes 7, thereby the inner circumferential surfaces are subjected to fluid machining action by the polishing liquid 6. Further, since the fluid resistance at both end open peripheries of guide holes 7 is largest, the corner-rounding is performed there, and at the same time ultrasonic oscillators 4, 5 oscillate to emit ultrasonic waves, and the ultrasonic vibration is transmitted to the polishing liquid 6 to vibrate it, thereby grains of polishing powder in the liquid are uniformly dispersed, thus smooth polishing surfaces can be obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce an exposed member to the utmost so as to lessen resistance by providing a rudder head shaft in a hull with the lower surface thereof on the same line with the ship's bottom, and projecting a rudder plate from the lower surface of the rudder head shaft. SOLUTION: A rudder head shaft 14 is provided in a hull 12 with the diameter thereof set equal to the longitudinal length of a rudder plate and with the lower surface of the rudder head shaft 14 on the same line as the ship's bottom. In this case, the rudder head shaft 14 is freely rotatably supported with radial load and thrust load applied to a rudder trunk 30 welded or bolted to the hull 12. Accordingly, there is only the rudder plate 16 below the line of the ship's bottom 28, and there is no member which increases resistance. Needless to say, the rudder plate 16 can be applied to a normal monoplane rudder. Also in the case of the normal rudder, a rudder shaft and a flange are exposed to the outside of the hull, which become resistance unexpectedly. So the effect is large.
