Abstract: PURPOSE:To raise precision of the supporting part of a fixing shaft, and to set ball bearings always concentrically with the center of the fixing shaft, by forming a supporting yoke in an integrated one body by die casting. CONSTITUTION:A die cast supporting yoke 20 is constructed with a supporting block 21 and a pair of supporting plates 22, 22, which are extended diagonally from both lower sides of the block 21. In the center of the block 21, a fixing hole 23 is formed as it pierces through the upper part/the lower part of the block 21, and in this fixing hole 23, radial ball bearings 24, 24 are inserted with a spacer 24a between. Through the inner rings of the ball bearings 24, 24, a fixing shaft 25, the upper end of which is fixed to the side to be fixed, is inserted, and this fixing shaft 25 is supported with the upper end of the supporting yoke 20, as it can rotate freely. As the supporting yoke 20 is formed in an integrated one body by die casting, the precision of the supporting part of the fixing shaft 25 is raised, comparing with a press-processed supporting yoke.

Abstract: PURPOSE:To secure a sufficient margin by transferring data read for a half time after they are written into a second storing means and read from the second storing means for a remaining time after the time of the writing prohibition is secured, into a first storing means. CONSTITUTION:A data transfer control circuit 13, after digital recording data 101 to be inputted are written into a RAM 12 in a 1 frame unit, reads them in the one frame unit and outputs them to an interleaving and deinterleaving circuit 2.

Abstract: PURPOSE: To ensure the opening and closing operation of a door by judging an increase in door driving load only when the actual door opening and closing time exceeds a prescribed allowable range to a target value, and changing the door motor driving pattern. CONSTITUTION: When a door close instruction 1B (or door open instruction 1A) is outputted from an elevator control board 1, a door control device 2 outputs an optimum door driving pattern to control a door motor 11. At this time, the time between cam switches A, B detected by a door position detector 12 is measured by a door pattern setting device 20, and a CPU 21 reads and outputs a basic driving pattern from a memory device 22 when the measured time is within an allowable time, but reads and outputs, a maximum door driving pattern when it is judged that the measured time exceeds the allowable time. Thus, a door can be surely opened and closed by increasing the torque of the door motor even when the opening and closing of the door can not be smoothly performed by the wind pressure from a hall or the dust of a door sill.

Filed: 1985-11-01
Abstract: PURPOSE:To prevent spread of beam after deflection control by providing an electron beam supply means for combining a deflected metal ion beam with an electron beam having such charge density as approximately the same as that of the metal ion beam. CONSTITUTION:A copper ion beam 10 is deflected by a deflection electrode 5 while controlled to be focused onto a point, e.g., point P, on the surface of a printed board 9 by means of a focus control electrode 6. Deflection control of the deflection electrode 5 is performed in two-dimensional side in accordance with a wiring pattern to be formed on the surface of the printed board 9, while focus control by means of the focus control electrode 6 is performed simultaneously. The copper ion beam 10 subjected to deflection control and focus control is led to an electron beam supply section 7 and combined with an electron beam emitted from an electron gun 8 with approximately the same charge density as that of the copper ion beam, then radiated onto the surface of the printed board 9 under electrically cancelled condition. Since repelling force will never function between the copper particles, spread of the beam can be prevented.
