Title: Composite target
Inventor: GOTO HIDEKI
IPC: C23C14/34
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To improve an etching property of a target by dividing a target on a backing plate into two or more and constituting the target composed of In2 O3 and SnO2 and the target composed of two kinds of oxides as one target. SOLUTION: Plural pieces of targets 1 composed of In2 O3 and SnO2 and targets 2 composed of two kinds of oxides are alternately arranged on a packing plate and are joined. In the target 1, the atomic ratio of Sn/In+Sn is preferably regulated to 0.01 to 0.2. In the case the atomic ratio is less than 0.01, its specific resistance increases, and also, it is made yellow. In the case the atomic ratio exceeds 0.2, the specific resistance increases, also, its chemical resistance improves, and its etching properties deteriorate. The target 2 is preferably composed of multiple oxides selected from among In-Zn, In-Mg, In-Ga, Sn-Zn and Ga-Zn.

Title: Reception common amplifying system
Inventor: ARAI TOSHIAKI
IPC: H04B1/44
Filed: 1982-10-19
Abstract: PURPOSE:To reduce the number of feeders for connection to a station down to just one and to reduce the cost for installation of feeders by collecting feeders for transmission and reception signals into one feeder by means of a circulator at a place near an antenna. CONSTITUTION:Isolators 24 and 25 and a circulator 22 are provided at a place near an antenna 1. The feeders which connect an antenna part and a transmitter/ receiver part are limited just to a feeder 28. At the transmitter/receiver part a circulator 23 and isolators 26 and 27 are connected to the feeder 28 led from the antenna part. Therefore the transmission and reception signals are extracted independently of each other, and each of these signals is connected to transmitters 17-19 and receivers 10-12 respectively. This system has no difference is in terms of performance from a conventional system which includes two feeders to connect the antenna part and the transmitter/receiver part. In case the outputs of transmitters 17-19 are large and the leakage level is high from a circulator 2 to a reception signal system, a band-stop filter means is set between an isolator 3 and a low noise amplifier 5.

Title: Manufacture of nonvolatile memory
Inventor: OKABE SHOJI
IPC: H01L29/78
Filed: 1987-07-21
Abstract: PURPOSE:To reduce a leakage current due to a parasitic MOS transistor of a bird beak section and to obtain a nonvolatile memory having stable characteristics by forming an impurity layer on an element isolation region, then forming a sidewall antioxide film on the sidewall of the antioxide film, and then selectively oxidizing it. CONSTITUTION:A first conductivity type semiconductor substrate 10 is oxidized to form a pad oxide film 34. and an antioxide film 16 is formed on an element region 12. Further, an impurity layer 20 is formed on an element isolation region 14. Then, a nitride film is deposited on the whole surface, and a sidewall antioxide film 18 is formed by anisotropically etching on the sidewall of the film 16. Then, an element isolating insulating film 22 is formed on the region 14 by selectively oxidizing. The layer 20 is diffused depthwisely and laterally of the substrate 10 in the selectively oxidizing step to form a higher impurity concentration layer 20 than that of the substrate 10 also on the region 12. As a result, since a bird beak section is disposed on a high impurity concentration layer, the threshold value voltage of a parasitic MOS transistor is enhanced to reduce a drain current of a leakage current at a low gate voltage.

Title: Semiconductor laser device and its manufacture
Inventor: MITSUI SHIGERU
IPC: H01S5/065
Filed: 1988-07-20
Abstract: PURPOSE:To realize a size stably by a method wherein a thickness of a second clad layer other than a stripe-shaped ridge part is specified and a p-type, an n-type or an intrinsic AlzGa1-zAs buffer layer which has been inserted so as to set a distance from an active layer to a current-blocking layer at a prescribed value is provided between the second clad layer and the current-blocking layer. CONSTITUTION:A thickness of a second clad layer is set at 0.3mum or lower; a p-type, an n-type or an intrinsic AlzGa1-zAs buffer layer is formed between the second clad layer and a current-blocking layer. A distance a', between an active layer 3 and the current-blocking layer 5, as one of important parameters deciding a laser oscillation mode is set by a thickness (a) of the second clad layer and a thickness (b) of a buffer layer. That is to say, the laser oscillation mode is decided by a concentration of a carrier injected into a laser oscillation region A, by an optical density and by a situation that a light guide effect by light absorption in a region B is balanced delicately. This balance is largely influenced especially by a thickness of the active layer, a width (w) of a ridge and a size of the distance a' between the active layer 3 and the current-blocking layer 5. When the thickness (b) is controlled by introducing a buffer layer 9, the size of the a' can be controlled with good accuracy.

Abstract: PURPOSE:To easily operate a keyboard by applying prescribed work to an inputted character code when the same key is continuously depressed by the specified number of times to input the character code, and in the other case, outputting the inputted code itself. CONSTITUTION:While comparing and referring the history information of the past input code stored in an input code storing means 6 and character I/O history information stored in a processing information storing means 5, an input code deciding means 2 determines an output pattern corresponding to a character code for one character keyed from an information input device 1 such as a keyboard. An output means 3 updates the information stored in the means 5, 6 in accordance with the output pattern determined by the means 2. Whether in the character code is inputted by continuously depressing the same key be the specified number of times or not is decided, and when the decision is positive, the prescribed work is applied to the input code by an input code working means 4. When the the input of the character code does not correspond to the decision reference, the inputted code itself is outputted. Consequently, key operation on the keyboard, especially operation relating to shift key operation can easily be executed.

Filed: 1993-07-23
Abstract: PURPOSE:To precisely recognize an edge shape by jointly using a rectangle measuring method and a density picture method, producing the height of an edge with a result by the rectangle surveying method and producing the outline of the edge with a result by the density picture method. CONSTITUTION:When a surface shape is obtained by the rectangle surveying method for an object 1 having a vertical surface 1c between a higher surface 1a and a lower surface 1b, an edge 1d that higher surface 1a and the vertical surface 1c makes, really ought to have the outline in a broken line position in the drawing (b), in the rectangle surveying method, however, since a system skips when point data of one survey point p1 is obtained and point data of a next survey point p2 is obtained, the outline becomes a vague one having width W, but the height position is precise. On the other hand, since a clear density change appears in the broken line position of the drawing (b) in the density picture method, the part can be judged to be the outline of the edge 1d. Therefore, the rectangle surveying method and the density picture method are jointly used and the height position is produced in the former and an outline position in the latter.
