Title: Image pickup device
Inventor: YASUDA KENTARO
IPC: H04N1/113
Filed: 1986-11-19
Abstract: PURPOSE:To pick up the image of an object reflecting weak light with priority given to high sensitivity and the image of an object reflecting strong light with priority given to high resolution by switching the connection of a bias-supply power source to supply bias voltage to an optical sensor. CONSTITUTION:In case the output of the bias-supply power source 8 is impressed to the bias electrode 5 of the optical sensor 4, the minority carriers generated corresponding to the intensity of light of an image formed by an image forming lens 1 pass through the part B of the sensor 4 along with the image, and reaches a part A as being integrated, then are taken out from a read electrode 7 as a potential variation proportionate to the quantity of themselves. In this case, the sensitivity is made high in the effect of said integration, but the resolution is poor because of diffusion. In case a bias-supply change over switch 9 is switched, minority carriers move in the opposite direction of that the image moves in, hence they do not reach the read electrode 7, therefore, the minority carriers generated corresponding to the intensity of light of the image in the part A of the optical sensor 4 are instantly taken out from the electrode 7 as a potential variation. In this case, because there is no integration effect, the sensitivity is low, but the resolution is excellent, for there is not the effect of diffusion.

Filed: 1989-10-24
Abstract: PURPOSE:To improve visibility of information displayed on a screen by erasing a switch pattern after it is displayed for a prescribed length of time and displaying an object if it comes to a prescribed scope from the screen. CONSTITUTION:When the screen is touched by an object with map information, etc., displayed on a CRT screen 26, scroll keys S1 to S4 and enlargement/ reduction switch patterns W1 and W2 are displayed on the map screen.

Title: Semiconductor device and its production
Inventor: YAMAGISHI MACHIO
IPC: H01L29/78
Filed: 1995-10-25
Abstract: PROBLEM TO BE SOLVED: To reduce the joint area of a source/drain diffusion layer and realize a high-speed operation of a device by covering the side wall of a spacer with a conductive layer for the contact connecting electrically with the source/drain. SOLUTION: A spacer 24 is formed on the side part of a gate electrode 31 and a source/drain area is formed by using it as a mask. A conductive layer made of polysilicon, etc., is piled up through a CVD method, and a resist, etc., are formed on the conductive layer, then the resist is left in the recessed part of the surface of the flattened element. Further it is entirely etched through reactive ion etching, so that the polysilicon remains in a self-alignment contact hole and a conductive layer 32 for the contact is formed as a result. Thus, the layer 32 is also formed on the surface of the source/drain area as well as the side wall of the self-alignment contact hole, that is, the side wall of the spacer 24 and the side wall of a field oxide film 21. The contact formation area is enlarged from the conventional L' to L, so the area of the source/drain diffusion layer can be reduced.

Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To realize the reduction of polish slurry consumption, the prevention of microscratch and the stabilization of a polishing rate and a surface inside polishing amount simultaneously. SOLUTION: This method has a dressing process for forming a nap layer by the dressing of a polish pad 2 and a chemical mechanical polishing process for flattening by chemical mechanical polishing by push-pressing a wafer 4 surface having a step to the polish pad 2. A process for push-pressing a spatula 11 consisting of a material having rigidity and elasticity on the polish pad 2 and raking out an impurity left in the nap layer of the polish pad 2 is applied just after at least either one side of the dressing process or the chemical mechanical polishing process. Thereby, a polish rate is stabilized and the generation of a microscratch to the wafer can be prevented. The uniformity of polish becomes possible by the less amount of polish slurry.

Abstract: PURPOSE:To improve the reliability of a semiconductor device by forming an insulating layer of multilayered structure that an impurity concentration is varied in multiple stages to form a smooth taper on the side of a contact hole formed in the layer, thereby improving the step coverage and removing defects, such as stepwise disconnection of aluminum wirings, etc. CONSTITUTION:CVD films 11, 12, 13 of low, middle and high concentrations of impurity are sequentially laminated on a semiconductor substrate 1, and a contact hole 26 is formed by isotropically etching on an insulating layer 25 of a 3-layer structure. Accordingly, the etching velocity is delayed slower at the lower part of the layer 25, the distance of lateral etching is shortened to form smooth taper on the side of the hole 26. Thus, a step coverage is improved to eliminate a defect due to the stepwise disconnection of aluminum wirings.

Abstract: PURPOSE:To perform good multicolor printing by simple constitution, by selecting a predetermined character group on the basis of an input control code and determining the predetermined memory part of a character pattern corresponding to the selected character group and developing the character pattern on the predetermined memory part determined based on an input character code to print the developed character pattern by the color corresponding to the color of the memory part. CONSTITUTION:When the data received from a host computer 30 is a character group selecting command, at first, a control code showing which character group among character groups 2-n said data falls under is detected from the character group selecting command and the detected character group is selected. For example, a character group 2 composed of a Gothic type character group other than a default character group 1 is selected. Then, the color selection falg '0' of this character group 2 is set to a color selection flag buffer 8. By this method, the character code corresponding to one page is received in the same way as the default character group 1 to perform color printing processing. However, since the color selection flag of the character group 2 is '0', a character pattern is developed on BMM-(B) and blue color printing processing is taken.

Filed: 1985-12-13
Abstract: PURPOSE:To use both sides of a coil, to reduce copper losses and to improve efficiency by constructing a magnet of two magnets with different magnetizing directions and inserting an overall frame-shaped drive coil into a magnetic circuit. CONSTITUTION:The magnetic circuit of a rotary actuator is constructed of the magnet 4 magnetized on tow poles on a single surface so that the magnetizing directions can be reverse of each other. The frame-shaped tracking drive coil 3 is inserted into the magnetic circuit not to one side but the entire surfaces.
