Title: Free float type trap
Inventor: FUJIWARA YOSHIYASU
IPC: F16T1/22
Filed: 1989-12-05
Abstract: PURPOSE:To prevent erosion of inner wall of an outlet passage by forming the inner wall surface of the outlet passage with which condensed water flow flowing out from a valve port collides directly in such an angle that the center axis of the valve port is made to reflect nearly to the center axis direction of the output passage, and still more, forming the center of the inner wall surface to a spherical surface of a concave shape. CONSTITUTION:High speed condensed water flow flowing out from a valve port 38 collides with a concave shape spherical surface part 42 opposed to the valve port 38, of the inner wall surface of an output passage 39. The collided condensed water flow flows along the spherical surface, separates from the spherical surface part 42 as being slowly converted in the direction of the flow, rises in the outlet passage 39, and goes to the outlet 22. At this time, the condensed water flow is converted in the flow direction thereof to nearly the same direction as the center axis of the outlet passage 39 by the spherical surface 42, and flows without collision with the inner wall of the outlet passage 39. Moreover, the condensed water flow flowing in the spherical surface 42 flows smoothly in a nearly laminar flow stage, therefore the same does not erode the spherical surface 42 remarkably.

Title: Printer
Inventor: MORI MASATO
IPC: B41J29/50
Filed: 1988-12-15
Abstract: PURPOSE:To adjust a printing-start position simply only by operation from a console panel by specifying the printing-start position on the basis of an output from an A/D converter converting the change of the resistance value of a rotary type potentiometer into a digital signal, setting the range of printing in the line direction and executing printing. CONSTITUTION:When printing is conducted while using a printing-start position as a position A, a pointer 4a is set at the location of the scale of '2' shown in a column scale 7. The resistance value of a potentiometer 4 is changed by the revolution of the potentiometer 4 while being synchronized with the angular rotation of the pointer 4a, and a current value varied by the alteration of the resistance value is transmitted over an A/D converter 9, and converted into a digital signal. A printing control section 10 determines the printing-start position by the reception of the signal, sets the range of printing corresponding to the printing-start position, and controls the printing-start position of a printing head 1 moved by a spacing motor 11. Accordingly, No.1 column of printing can be used as the position A.
