Title: Electrostatic coater
Inventor: KADOWAKI TOSHIYUKI
IPC: B05B5/04
Filed: 1982-02-19
Abstract: PURPOSE:To facilitate the supply of air to the peripheral part of a cup to be coated, by branching compressed air to be sprayed from the rear periphery of the cup to be coated from the central part to be supplied to an inserted body for coating work. CONSTITUTION:An air-spraying ring 39 is attached to the rear of the periphery 14 of a cup 1 to be coated, and compressed air supplied from the hollow part 35 of a rotary shaft 33 to the air-supplying part 24 of an inserted body 22 flows through air-flowing holes 26, 27, 21 into the air-spraying ring 39. The air is then sprayed toward the periphery of the cup 1 to be coated through many air-spraying nozzles 42 formed at the front part of the air-spraying ring 39 along its circumference. At this time, the speed of the air stream becomes slow since the air stream is widened until it reaches a knife edge part at the front end of the cup 1 to be coated. Consequently, drying the paint is not accelerated.

Title: Laser beam marker device
Inventor: IMAI SHINJI
IPC: B23K26/064
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a laser beam marker device to mark a work without distorting a letter and figure. SOLUTION: A data supply control means 17 arranged with a laser beam marker device successively fetches out a coordinate data from a storage means 16 to be given to a galvanomirror device 11. When the fetched coordinate data are the coordinate data of a peculiar point, a next coordinate data are not given to the glvanomirror device 11, until an irradiating point is stopped at the peculiar point, a next coordinate data are not given to the galvanomirror device 11. By this method, in causing a follow up delay, marking is surely done up to the peculiar point. Further, because the data supply control means 17, when an irradiating point stops at each peculiar point, under this condition immediately gives a next coordinate data to the galvanomirror device 11, an excessive wait time is not required at each peculiar point, so that the marking is quickly done.

For example, when a thyristor is short-circuited by error during the power driving operation, a field current flowing through the field winding 7 is branched in the electric path of the thyristor 12, and the field current is reduced. As a result, the terminal voltage of the main motor decreases, and the current increases. It is detected that a current flows through the electric path of the thyristor 12 by a current detector 13, and an interruption command is issued to an interrupter 8, thus the motor being cut off from the feeding circuit.
