Inventor: KITAZAKI KENZO
IPC: C23C18/12
Filed: 1992-01-31
Abstract: PURPOSE:To stably form a good-quality and uniform thin film on the principal plane of a substrate with higher efficiency and productivity by using this device. CONSTITUTION:The hearth surface 22 of a film forming device 4 is graded so that the part intermediate to the spray discharge port 9 and exhaust port 21 is made highest. The spray flows from the discharge port 9 toward the exhaust port 21 along the gradient of the hearth surface 22 and is brought close to the principal plane of the substrate 6 when the surface 22 approaches the lower surface of the substrate 6. Consequently, the chance for the spray to form a thin film is increased, and the amt. of spray contributing to the formation of the thin film is increased. Meanwhile, the access of the unstable spray part, namely the discharge port 9, to the substrate 6 is avoided, the spray is brought close to the substrate 6 at the part where the spray flow is most stabilized, and hence the uniformity and quality of the thin film to be formed are not deteriorated.

IPC: G05B19/02
Filed: 1986-03-05
Abstract: PURPOSE:To easily and completely design a stepsequence system by performing an interactive operation with reference to a sequence design screen, a time chart screen and a shift condition screen. CONSTITUTION:When an operator selects a sequence design mode at the starting time of a designing action, a basic pattern DD of an area 3D of a ROM 3 is read and displayed. At the same time, the file contents developed to an area 5D of a RAM 5 are displayed at the corresponding part on a screen. Then the operator supplies the information to the screen DD of a table form via a keyboard 9B. Thus it is checked whether said input of information indicates the end of the sequence design mode or not. If not, the input information is developed to a sequence design file 5D as well as to the areas corresponding to a time charge file 5T and a shift condition file 5C respectively. Thus it is possible to easily design a step sequence system at a low cost by carrying out an interactive operation with reference to those three different types of screens.

Title: Connector for printed circuit board
Inventor: DOI ETSURO
IPC: H01R13/64
Filed: 1994-02-21
Abstract: PURPOSE:To mount a connector certainly on a printed circuit board. CONSTITUTION:A connector for printed circuit board includes a lead 33 and an upward motion preventing member 7, with which the whole lead part is hindered from upward motion and deformation relative to a housing even when an upward directed force is applied to the lead 33 through the action of the upward motion preventing member 7 which is contacted with the oversurface of the middle part 33a. Accordingly the lead 33 remains without upward motion even though an upward directed reactive force is applied from the printed circuit board P to the lead part which has not been inserted in a through hole H due to deformation of the end 33b, etc., caused by any external force, and with the resistance against upward motion, the housing 1 can not be pressed properly to the circuit board P. This permits knowing that any of a number of leads can not be inserted in the through hole due to deformation.
