IPC: H05B33/10
Filed: 1988-09-14
Abstract: PURPOSE:To obtain high brightness and stabilization of luminous property by having no dead layer formed in a luminous layer and no impurities such as halogen elements or others contained therein. CONSTITUTION:Before a luminous layer 14 is formed on the surface of one insulation layer 11 on a board side, the surface of the insulation layer 11 is cleaned and activated. Then, the surface of the activated insulation layer is kept in a heated state and exposed to sulfidization-reactive gas or oxidization- reactive gas, so that on the activated surface 12 a rough layer 13 is formed, over which atoms as a main element of reactive gas are spread in order. On such a rough atomic layer 13 an EL luminous layer 14 is formed by a forming material other than halide, so that such a problem that a ill-crystallized dead layer arises early in forming the luminous layer can be dissolved and such a case that halogen elements are contained in the luminous layer as impurities can be eliminated. Luminous brightness is thus enhanced and luminous property is stabilized.

IPC: D01H1/36
Filed: 1993-09-17
Abstract: PURPOSE:To obviate the test operation for getting a setting condition to stop a lifting member to a preset stop position. CONSTITUTION:Both of a ring rail and a spindle are rotated by the driving force of a main motor. The ring rail is vertically reciprocated by the driving force of the main motor at a stroke almost equal to the chase length C. When a stop button is pushed during the operation of the ring rail, the rotational speed of the spindle is set to be decelerated and stopped following a specific deceleration pattern shown in the figure. When a stop signal is inputted from a stop button, the deceleration starting position Px to enable the stop of the ring rail at a preset stop position Ps is calculated as a pulse value Cx by a CPU for controlling the drive of the main motor based on the program data stored in a program memory of the CPU. The CPU drives and stops the main motor according to the deceleration pattern shown in the figure when the count of a counter circuit to detect the position of the ring rail reaches the pulse value Cx.
