Title: Coating device
Inventor: OSHINO TOSHIKAZU
IPC: H01L21/56
Filed: 1985-04-12
Abstract: PURPOSE:To prevent uneven coating and thickness and to coat uniformly by detecting the position of a material to be coated with a position detecting mechanism and relatively changing the position of a coating nozzle on the basis of the signal. CONSTITUTION:In the coating operation in the production of semiconductors, etc., a pellet 8 to be coated is placed on a coating stage 7 and the position information is obtained by a position recognizing mechanism such as a terecamera 11 and transmitted to a position control part 12. A base 2a and a saddle 2B are moved by the position control part 12 so that the image of the pellet 8 is present in the visual field of the terecamera 11 and a lift table 4 is moved so that the pellet comes directly below a coating nozzle 6. The discharge and temp. of a viscous resin 6a are regulated by the program inputted to a discharge condition control part 14 and the resin is discharged. The position of the nozzle 6 with respect to the pellet 8 is thus specified to prevent the unevenness and to coat uniformly.

Title: Electromagnetic drive valve
Inventor: KATSUMATA MASAJI
IPC: F01L9/20
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce the drive force to be transmitted to a zero-rush adjuster keeping operation noise within a permissible range in relation to an electromagnetic drive valve provided with the zero-rush adjuster. SOLUTION: An electromagnetic drive valve 10 is provided with a zero-rush adjuster 40 between a valve element 12 and an armature shaft 42. When the electromagnetic drive valve 10 closes, hydraulic oil pressure is applied to the zero-rush adjuster 40, extending the zero rush adjuster 40, resulting in the prevention of the production of a gap between the valve element 12 and the armature shaft 42. Hydraulic pressure is applied to the zero-rush adjuster 40 by a hydraulic pump 86. While an internal combustion engine is running at a high speed or with a high load or when the valve element 12 is heated at a high temperature, the hydraulic pressure Pe applied to the zero-rush adjuster 40 is reduced, or the hydraulic pump 86 is made to stop.
