Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device of a structure, wherein even though a step is generated in element isolation regions, a short circuit between contact plugs can be prevented from being generated and the full reliability of the device can be ensured without making wiring expose, and a manufacturing method of the device. SOLUTION: This manufacturing method is a method wherein element isolation regions 13 are formed on a semiconductor substrate 11, and the substrate 11 is sectioned into a plurality of element regions 12. After that, word lines 14 are formed on the substrate 11 and the peripheries of these word lines 11 are covered with a protective film. After impurity diffused layers are formed in the regions 12, a plug insulating film is formed on the whole upper surface of the substrate 11. Apertures 18a linking the end parts of the regions 12 to each other are formed in this plug insulating film. A conductor film is buried in these apertures 18a and, until either of a protective film on the regions 13 and a protective film on the regions 12 is exposed, the conductor film and the plug insulating film are polished by a CMP.

Title: Television camera device
Inventor: YOSHIMURA YASUO
IPC: H04N5/235
Filed: 1993-03-31
Abstract: PURPOSE:To photograph the pictures of an object changing from high illuminance to low illuminance in best picture quality by consecutively controlling control means in a prescribed order corresponding to an incident light quantity. CONSTITUTION:When object illuminance drops from the high illuminance to the low illuminance, sensitivity is controlled by increasing the incident light quantity so as to hold the level of video signal output (a) by a lens iris control circuit 8. When a lens iris is opened, other sensitivity control is switched to. Then, the sensitivity is controlled by raising the sensitivity of an image pickup tube by an image pickup tube target voltage control circuit 14. When the sensitivity control comes to a limit, the next other sensitivity control is switched to. Then, the sensitivity is controlled by the variable gain control circuit 10 of a video signal amplifier circuit. In such a manner, by appropriately, automatically and consecutively using three kinds of sensitivity control means corresponding to the object illuminance so as to reduce picture quality degradation as much as possible, the sensitivity control provided with a wide dynamic range is performed.

IPC: H03F3/68
Filed: 1982-04-30
Abstract: PURPOSE:To prevent a BTL amplifier from being destroyed, by detecting an amplifier output voltage of each BTL amplifier section forming the BTL amplifier and comparing the output voltage. CONSTITUTION:The BTL amplifier consists of the BTL amplifier sections 5, 10 for L and R channel. The output of amplifiers 2, 3 and 7, 8 of the amplifier sections 5, 10 is given to detection circuits 17, 18 via terminals 13, 14 and 15, 16. Detection signals of each detection circuit are given to a comparison and detection circuit 19 and compared. Since no output is generated from the circuit 19 at the normal operation, no control signal is outputted from a control signal generating circuit 20 of the next stage. Further, at an abnormal operation, the circuit 19 is operated, a control signal is outputted from the circuit 20, and then the amplifier function of the sections 5, 10 is stopped. Thus, the destruction in the BTL amplifier is prevented.

Title: Display device
Inventor: MIZUKI TATSURO
IPC: G02F1/13
Filed: 1990-03-23
Abstract: PURPOSE:To make light incident on all over the surface of a display element at a uniformly fixed incident angle and to obtain an image display having high contrast by forming a surface which is cut to a shape like a saw-tooth on one surface of a substrate on an incident side. CONSTITUTION:The surface of the substrate (a) on the incident side on the light source side is cut to the shape like the saw-tooth. In the case of numbering the surface cut to the shape like the saw-tooth 1, 2, 3,... from left, it is desirable that the odd numbered and even numbered surfaces are respectively parallel with each other. This is because the light made incident on each surface can thoroughly reach a display surface A at the same angle. The angle theta1 of the cut to the shape like the saw-tooth depends on the angle theta2 of the incident light made incident of a boundary between the substrate and a material whose refractive index is changed by an electric field action. It is important that the incident angle theta2 on the boundary is the angle by which both state of total reflection and transmission can be made.

IPC: G09F11/23
Filed: 1992-03-30
Abstract: PURPOSE:To smoothly control the rotation of a display rotating body and to precisely position a display surface with respect to a display direction. CONSTITUTION:When an electromagnet 31 is magnetized to N under a state that a non-display surface 27 is displayed by the display rotating body 21, the potential energy of the display rotating body is changed. Then, repulsive force acts on the N pole of a permanent magnet 22 and attracting force acts on the S pole. Besides, rotational force acts on the display rotating body and the display rotating body is started to be rotated in a direction shown by an arrow A. At the same time that the display rotating body is started to be rotated, the rotational force acts also in a direction shown by an arrow B by a ferromagnetic plate 30 to 90 deg.. When the rotational angle of the display rotating body exceeds 90 deg., the magnetization of the electromagnet is stopped after the angular velocity of the display rotating body sufficiently becomes small before it is rotated to 180 deg.. Then, when the potential energy of the display rotating body is returned to a state that it is not magnetized, the display rotating body is kept at a position where the display surface 26 is displayed while it is attenuated and moved.
