Title: X-y address type solid state image sensor and its fabricating method
Inventor: SUZUKI RYOJI
IPC: H04N5/374
Filed: 2001-07-11
Abstract: PROBLEM TO BE SOLVED: To solve the problem of such a pixel structure as the incident light is taken into a photodiode through an interconnect layer that a part of light condensed through a microlens is sputtered by the interconnect.

Title: Planar lighting device
Inventor: SUZUKI SHINGO
IPC: F21V8/00
Filed: 2001-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a planar lighting device which aims at improving the effective use of light from a light source. SOLUTION: A reflecting plate 14 is fitted on a face 6a opposite to a transparent substrate of a light guide body 6 (the rear face of the light guide body 6). On a first face 14a of the reflecting plate which faces a light guide body 6 of the reflecting plate 14, triangular prism convex parts 17 extending toward the direction orthogonal to the light guide body (the direction of crossing the optical axis A) are arrayed in plural number in the longitudinal direction of the reflecting plate 14, to form a convex part row. A reflecting layer 16 is formed on the surface of the convex part row. Light, transmitting the slanted wall of the light guide body 6, is readily reflected in the direction of the light axis A by the reflecting layer 16, easily to become an effective light.  With reflecting materials of the conventional technology, much non-effective light is generated radiating toward directions with large angle of sight and, therefore the effective use of light from the light source is limited by that much; but since generation of non-effective light is restrained to be minimum, improvement can aim at in effective use of light from the light source 4.

Title: Semiconductor device and its manufacturing method
Inventor: OTSUKA FUMIO
IPC: H01L27/088
Filed: 2001-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a technique for inhibiting variation in a threshold voltage, and for increasing switching speed in a short-channel MISFET. SOLUTION: On the entire surface of a substrate 1 below the channel region of the MISFET, p-type impurity layers 7 and 8 are formed, thus inhibiting the variation in the threshold voltage as compared with a case where a punch- through-stopper layer with a pocket structure is formed. In this case, the p-type impurity layers 7 and 8 have first and second peaks, respectively, in an impurity concentration distribution having a function for preventing punch through. Additionally, the width of a controllable depletion layer becomes relatively large, thus reducing a subthreshold coefficient, and hence preventing the drop of the threshold voltage for increasing the switching speed in the MISFET.

Title: Locking screw component
Inventor: YOMO SUZUKO
IPC: F16B39/282
Filed: 2001-07-27
Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain a screw component exerting a certain locking effect with a simple structure. SOLUTION: In the screw component 1 comprised of a head portion 2 and a leg portion 4 formed of a screw thread 3, a projection 11 projecting in a pyramid-shape is arranged on a seat surface in the circumferential direction at a plurality of equal intervals. Since a ridged line 12 of the projection 11 is a locking screw component turning to a screw-fastening rotative direction, when the locking screw component is fastened to a work applied with corrosion preventive treatment by means of a special organic film for making influence to an environment reduced in recent years, a frictional coefficient is increased right before seating of the screw component, and the projection is cut into the work by canceling slippage and by surely breaking the surface of the work.  Further, the destruction of a female screw is hardly produced so that a axial force generated when completing fastening of the screw is not suddenly increased from a preset value. Furthermore, cutting-into the work by the projection is facilitated so that the ridged line of the projection existed in the screw- fastening rotative direction.
