Title: Hardening method for inside surface of steel pipe by plasma jet
Inventor: MIHARA TAKAO
IPC: C21D1/09
Filed: 1982-09-06
Abstract: PURPOSE:To maintain a voltage constant and to form a good hardened layer to a uniform depth even when the inside surface of a steel pipe is rugged by rotating the pipe at a low speed and moving the preceding end of a torch forward and backward while maintaining a specified distance from the inside surface of the pipe. CONSTITUTION:A plasma jet torch 2 is located in the end part of a steel pipe 1 so as to face the inside surface thereof. While the torch 2 is moved in the axial direction of the pipe 1, which is kept rotated at a low speed, by a weaving device 6, plasma jets are ejected from the torch. A voltage is compared with a reference voltage and is differentially amplified by an automatic correcting device 7 for vertical positions by making use of the change in the voltage when the distance from the preceding end of the torch 2 and the inside surface of the pipe changes. In accordance with the compared value, the supporting arm 21 for the torch 2 is moved vertically by means of a servocontrol unit 71 along the sliding base on the device 6. As a result, the distance between the plasma jet injecting position on the inside surface of the pipe 1 and the torch 2 is kept constant.

Abstract: PURPOSE:To form a pattern arbitrarily in a transparent body and to simplify the working by a method wherein a synthetic resin for forming the body is supplied to a molding tool in a melting state, and a melting synthetic resin for forming a pattern is added therein and fluidized. CONSTITUTION:An acrylic resin becoming colorless and transparent in a set state is melted to be casted into a molding tool 1. On the upper surface of a melting resin layer 2, a pattern plate 3 to be embedded inside is loaded in a levitating state. On the resin layer 2 and the pattern plate 3, a melting acrylic resin is gradually casted, whereby the pattern plate 3 is held along the interface of a resin layer 4 which has been supplied thereon. Furthermore, on the resin layer 4, a melting acrylic resin 5 for forming a pattern is mixed. In this manner, since both the resin layer 4 and the resin layer 5 are in a melting state and, thus, substantially freely fluidized, the resin 5 can be extended in a drawn direction or stirred to be spiraled. Therefore, the pattern with the resin 5 can be arbitrarily formed inside or on the resin 4 by appropriately conducting this operation.

Filed: 1999-06-03
Abstract: PROBLEM TO BE SOLVED: To shorten a processing time by simultaneously positioning a head which prints on a medium to a printing start position and transferring the medium to the printing start position. SOLUTION: A transfer motor for moving a medium A along a transfer path B is driven until a detecting means 11 detects the medium, and at the same time, positioning a printing head 15, namely, centering is started. A timer routine for stopping the transfer motor for the medium A is called, and the transfer motor is made to wait until the centering to the printing head 15 is completed. When the printing head 15 has been completely positioned when the detecting means 11 detects the medium A, the transfer motor is not stopped and is driven to transfer the medium A to a printing start position.  In the case where the transfer motor stops, the timer routine is released when the centering is completed, the transfer motor is started again to wait until a sensor 12 detects the medium 12, is kept waiting until the medium is transferred by a specific number of steps from the sensor 12 to the printing start position after the sensor detects the medium, and then printing is started. A time from setting the medium A to starting printing can be shortened accordingly.
