Title: Method of repairing existing pipe
Inventor: TOYODA SHIGERU
IPC: B05C7/08
Filed: 1995-03-29
Abstract: PURPOSE: To obtain required pressure difference without applying high pressure from behind resin and pig in a method in which the resin and the pig are advance to coat the resin on the inner surface of a pipe by applying positive pressure and negative pressure to behind the resin and the pig and to before them respectively. CONSTITUTION: When forming a lining film M on the inner surface of a used line 1 such as gas pipes, the resin in a resin injection device 16 and then a lining pig 12 are introduced into the line 1. After that, air from an air pump 18 is forcibly fed into the line 1, and at the same time, a suction pump 2 is driven. In this way, the pig and the resin A are pressurized and advanced to form a resin lining film M on the inner surface of the line 1. At this time, a positive pressure measuring and regulating means 11 is installed on the air pump 18 side to keep the pipe interior pressure (positive one) on the air pump 18 side in a prescribed range, and a negative pressure measuring and regulating means 10 is installed on the suction pump 2 side to keep the pipe interior pressure (negative one) on the suction pump 2 side in a prescribed range.

Title: Work machining method and device
Inventor: KUNIMI HOMARE
IPC: B23Q15/013
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To improve machining accuracy and decrease the occurrence of a defective product by machining a portion into the range of a tolerance again when the measured value of the machined portion after machining lies outside of the tolerance. SOLUTION: When the measured value of a machined portion lies outside of a tolerance after machining, a program for corrective machining is transferred to the control device 14 of a finishing machine 12 from a management device 16, the machined portion is again machined, the machining accuracy is improved and the occurrence of a defective product is decreased. A one-item production work having multiple machining portions can be easily coped with, i.e., the management device 16 and control device 14 function as control device means. Since the prescribed-program is transferred to the finishing machine 12 side from the upper-level management device 16 for machining and measurement, the program is prepared more efficiently.

Title: Aperture antenna
Inventor: TAKANO TADASHI
IPC: H01Q15/16
Filed: 1987-03-27
Abstract: PURPOSE:To decrease the number of face elements without deteriorating the antenna performance by constituting a main reflecting membrane by sets of planar polygons and selecting the length of sides of the polygons placed near the circumferential ridge where the electric field applied at the spray to the main reflecting mirror is weaker longer than the length of sides near the middle part where the electric field at the spray is stronger. CONSTITUTION:In forming radially sectorial parts whose center angle is 60 deg. from the center 12 of the reflecting mirror being a component of an aperture antenna, each sector is approximated by sets of triangles 6 whose side is gamma/10 (gamma is the radius of the reflecting mirror) up to a point 5 corresponding to 60% of the radius of the reflecting mirror. In addition, triangles 7 whose side is gamma/5 are used to approximate the sectors at the outside of the point 6. Thus, the gain reduction is within a range of 0.1dB because of the effect of less number of divisions at the circumferential parts in comparison with the approximation of the entire sector by triangles whose side is gamma/10. Thus, the number of face elements is reduced and this antenna is suitable for expansion antennas for space or the like.
