Title: Radiant beam current density measuring apparatus
Inventor: KUSUSE HARUHIKO
IPC: G01T1/29
Filed: 1989-03-29
Abstract: PURPOSE:To measure a correct radiant beam current density distribution and size by providing a shield section comprising a single crystal body on a path of a radiant molding beam. CONSTITUTION:An electron beam 2 is shielded with a single crystal silicon knife edge 5. As an electron beam 2 shielded with such a knife edge 5 is totally reflected, a part of the electron beam 2 will not be incident into a Faraday cup 3 by a scattering of the edge. Therefore, there is no softening in a current density signal waveform and correct beam dimensions can be obtained. As the knife edge 5 forms an edge surface for a crystal face, higher linearity and orthogonal property are achieved in the knife edge. Thus, a current density signal waveform is obtained free from softening without a deviation of fixing angle and an edge irregularity.

Title: Control method for charging air into or discharging from coating booth
Inventor: ITOU JIYOUJI
IPC: F24F7/06
Filed: 1980-06-13
Abstract: PURPOSE: To maintain an air balance in a coating booth even at the starting or stopping period of coating operation, by chronologically and linking together while controlling air-charge into an air-discharge from a coating booth.  
     CONSTITUTION: When operation in a coating booth is started, variable dampers 9, 10 are set in a completely closed state, and fans 7, 8 are concurrently driven, so that the air is not fed into a coating chamber 3 at this period. As a result, an air stream is not generated. Thereafter, the variable damper 9 is fully opened earlier, by a time necessary for introducing air through the variable damper 9 into the upper portion of the coating chamber 3, than the opening of the variable damper 10, in accordance with an indication by a damper's opening rate-controller 11. When the operation in the coating booth is stopped, the variable damper 9 is closed earlier, by the specific time difference, than the closing of the variable damper 10 in the same manner as at that at the starting period. After the variable dampers 9, 10 are fully closed, the fans 7, 8 are stopped. Consequently, the balance of an air stream in the coating chamber is not broken at the starting or stopping period of the operation in the coating booth.
