IPC: H01L33/30
Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To uniform superior for forward voltage and monochromatism of light emission superior by providing a Bragg reflection layer with an undoped region of a specified range from a surface, in contact with a first conductive type of clad layer. SOLUTION: A Bragg reflection layer 109 used for an A1GaInP light-emitting diode is constituted by a III-V compound semiconductor. For example, a first constituent layer 109a is of AlXGa1-XAs, and a second constituent layer 109b consists of AlYGa1-YAs, whose aluminum composition ratio is larger than it, to form the Bragg reflection layer 109. To provide the Bragg reflection layer 109 with an undoped region of a range 10 nm-100 nm from a surface in contact with a clad layer, a constituent layer of the Bragg reflection layer 109 in contact with the clad layer is undoped. If the Bragg reflection layer 109 is placed on a substrate side below a light-emitting part, a constituent layer of the Bragg reflection layer 109 in contact with the clad layer becomes the outermost layer of the Bragg reflection layer 109.

Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To collate an electrical code, and to enable correspondence at the time of trouble without damaging the function of a key device by inputting a code from an audio equipment in a compartment even when a radio signal cannot be received and transmitted. SOLUTION: A key 1 inserted into a key cylinder 5 is collated mechanically, and whether or not the key 1 is correct is decided by the reception and transmission of a signal electrically between a key-side signal receiving-transmitting means 4 and a cylinder lock-side signal receiving-transmitting means 5. When the signal cannot be received and transmitted due to trouble, a password signal from an audio equipment 10 in a compartment is input and an electrical code can be collated. The password number can be input only when the normal key of the key 1 inserted into the cylinder is decided mechanically, thus preventing the possibility of an erroneous input.

Title: Cmos integrated circuit and its manufacture
Inventor: MINNRIYAN SHIEN
IPC: H01L27/092
Filed: 1989-08-14
Abstract: PURPOSE: To enhance the characteristics of a channel device by a method wherein a channel insulating implantation of boron is performed in the same depth as the depth of a field oxide layer in a silicon substrate. CONSTITUTION: A photoresist layer 5 and an oxide layer 3, which are formed on a substrate 1, are patterned by such a method that a part, which is selected as a region for an N-type tab, of the substrate is exposed and a phosphorus layer 7 and an arsenic layer 9 are formed in the substrate by ion-implantation. Then, after the layers 5 and 3 are removed, the N-type tab is oxidized to form an oxide layer 11 and an N-type region 13. A boron implantation for a P-type tab is performed by such a manner that it is shown at a point 20 and a thermal diffusion is performed to form the N-type tab 15 and the P-type tab 17. Then, a boron implantation, which is shown in an opening 30, is performed in such a way that the peak boron concentration of implanted boron reaches to a place deeper than the depth of a field oxide layer, which is formed in the substrate.  Then, when vapor oxidation is performed, the amount of separation of the boron from the field oxide layer is decreased and the N-type tab oxide layer 11 is removed. Then, when patterning of an active layer and high-voltage field oxidation are performed, the field oxide layer 12, which is shown by thin oxide layers 19 and 21, is formed. Thereby, the electrical insulation and punch through characteristics of a channel device are improved and the utilization of a CMOS process to a submicron dimension can be facilitated.

Title: Small-sized electrophotographic copying machine
Inventor: SATOU MASAMICHI
IPC: G03B27/50
Filed: 1981-12-24
Abstract: PURPOSE:To make a copying machine small-sized and lightweight and to improve the efficiency of a light source, by converging light from a light source and by allowing an optical guide irradiating the surface of an original through the supporting body of the original to serve also as a function for holding a  supporting body of the original. CONSTITUTION:A light emitted from a light source 3 is fully reflected in an optical guide 4 and is condensed and irradiates an origial reading part through a plastic film 2. At the same time with the irradiation, an original placing plate stretchingly provided with the transparent plastic film 2 on which an original is set is brought close to a fiber array 6 and is moved to e.g. from the left end to the right end at the constant speed in synchronization with a photosensitive drum 8. The light which irradiates the original reading part is made incident to the fiber array 6 to form an image on the drum 8. As the film 2 on which the original 1 is set is supported with a top end of the optical guide 4 at the time of moving, the deformation of the film is prevented since the leakage of the light  at a contact part is less, a comparatively weak light source is enough.
