Abstract: PURPOSE:To execute the operation of a memory at a high speed by controlling a delay time of a delaying circuit by a detecting means for detecting a working variance of a process. CONSTITUTION:In an internal clock signal generating circuit PC, a detecting circuit CTR is a circuit for detecting a working variance of a process or a characteristic variance of an element such as a MOSFET, etc., generated by said variance, and by its output, a delay time of a delaying circuits DLY is controlled. Also, a driving circuit is constituted by cascading a CMOS inverter, etc. Accordingly, an increase portion of the delay time by the driving circuit is offset, and the dependency against a process working variance of the delay time which has added up the driving circuit part and the delaying circuit part DLY becomes small. In such a way, an operation speed of a memory array and the delay time of an internal clock signal can be brought to matching, and the operation of a memory can be executed at a high speed.

Filed: 1985-11-25
Abstract: PURPOSE:To keep insulation satisfactory between a substrate and a coil by employing a glass-burnt layer as an insulating layer, or further installing another insulating layer obtained by this film forming techniques on such a glass-burnt layer. CONSTITUTION:A glass layer 3a is formed on the overall surface of the substrate. For the formation, thin film techniques such as sputtering may be used, or glass particles settle on the substrate in an alcohol solution where glass droplets are scattered so as to form a glass layer. Then the substrate forming the glass layer is burnt at a temperature of a glass softening point or above, and the glass is again melted. If the glass layer is formed by the thin film techniques, defects in the layer can be eliminated by remelting the glass. Even if the glass attaching amount to a vertical wall in a recessed part is insufficient, said vertical wall is satisfactorily wet due to glass's wettability, and an excellent insulation can be attained.

Abstract: PURPOSE:To obtain a wide vertical diffusing characteristic and to cause the vertical diffusing characteristic from a front direction to be comparatively plane by providing an uneven surface for optical diffusion on a lenticular lens. CONSTITUTION:The uneven surface for optical diffusion in a sine wave shape to define the travelling direction of lenticular lens 11 and 12 is formed in the side of the lenticular lens 11 and 12 so that a phase with the adjacent lenticular lens 11 and 12 can be different by 180 deg.. In such a case, for the uneven surface for optical diffusion provided on the incident surface of a lenticular lens sheet, there is a feature in a cross section shape and a position and it is preferable to form the uneven surface for optical diffusion in the sine wave shape. Then, it is preferable for the fluctuation of the thickness of the lenticular lens sheet 1 by this uneven surface for optical diffusion to be 1-5% to the thickness. Thus, a view angle in a vertical direction can be widened by one lenticular sheet 1 without increasing a dispersing agent and the diffusing characteristic can be selected comparatively freely.
