Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To enable easier production with a small number of parts while securing a higher cooling efficiency by inserting a metal corrugated plate being cylindrically bent into an inner tube to be securely soldered at a contact point with the inner tube. SOLUTION: A metal corrugated plate 6 made up of a thin metal plate formed into a corrugation is previously coated with a solder paste at a ridge part thereof and elastically deformed into a cylinder to be inserted into the inner tube 1. As a result, the metal corrugated plate 6 is made to generate a springing force in the direction of expanding the diameter thereof to be held at a fixed position in the inner tube 1 pressing the ridge part into the inside thereof. The inner tube 1 thus obtained is placed into a heat treating furnace to be heated so that the solder paste is melted to solder a ridge on the periphery of the metal corrugated plate 6 on the internal surface of the inner tube 1. The soldered part is formed linearly inside the inner tube 1 along the length thereof thereby miminizing a pressure loss of an exhaust gas during the passage.

Title: Controlling method for dc motor
Inventor: KON TOMOHIRO
IPC: H02P7/06
Filed: 1980-12-25
Abstract: PURPOSE:To allow a space motor to follow up the printing operation when the operation is reset to the printing operation by maintaining a slice level to a  specified speed level when the motor is stopped or skipped. CONSTITUTION:When the speed of a space motor is higher than a specified speed, a signal S3 becomes ''1''. Then, a transistor Q1 becomes ON, while a transistor Q1 becomes ON, while a transistor Q2 becomes OFF. A charge current X flows, and a slice level S4 is raised. When it is lower than the specified speed, the signal S3 becomes ''0''. Then, the transistor Q1 becomes OFF, while the transistor Q2 becomes ON. Thus, the slice level S4 is lowered by a discharge current Y. When a stop command signal S7 or skip signal S3 becomes ''1'', the transistors Q1, Q3 become ON, while the transistor Q2 becomes OFF. Thus, the slice level S4 is maintained at the printing speed level.
