Title: Semiconductor device and manufacture thereof
Inventor: SAKAKIBARA TOSHIO
IPC: H01L27/092
Filed: 1990-05-11
Abstract: PURPOSE:To suppress the level difference, even in case of island isolation, by providing a semiconductor region having a specified thickness and a specified conductivity where the concentration of impurities lowers gradually from the surface toward the bottom face. CONSTITUTION:Wafers are stuck together by adhering oxide films 2, 5 each other, and then the other main face of a first single crystal silicon substrate 1 is polished so that the first single crystal silicon substrate 1 has a thickness thinner than 6mum, e.g. in the range of 1.5-2.5mum. The first single crystal silicon substrate 1 is then selectively etched to form island regions 6, 7 corresponding to the semiconductor region. A gate oxide film 10 is formed in the DMOS forming region and on the surface of the island regions 6, 7. P-type impurities, e.g. B(boron), are then ion implanted to form a P<->-type region 9 on the surface section of the island region 6. The impurities are dispersed upto the bottom face of the island region contacting with the oxide film 2. Since the impurities are dispersed in the island region 6, the impurities concentration lowers gradually from the surface toward the bottom face of the island region 6.

Filed: 1982-07-15
Abstract: PURPOSE:To raise the accuracy of a trouble diagnosis by comparing an output value from a detector for detecting a prescribed operating condition of an internal-combustion engine with a normal output region under a special operating condition. CONSTITUTION:An arithmetic circuit 4 reads the number N of engine revolution from a rotary sensor 2, decides whether N=0 or not (S1), and does not make a trouble diagnosis when Nnot equal to . On the other hand, the arithmetic circuit reads any output from an AD converter 3 at N=0 to decide (S2, S3) whether an intake air flow rate signal Q from an air flow meter 1 is within the set region or not, and outputs (S4) a specific bit ''1'' of a memory 5 when said flow rate is outside the set region to alarm the troubles of the air flow meter 1 via an alarm device connected to the memory 5. It is possible in such a way to raise trouble diagnosis accuracy.

Title: Burning method of combustible gas
Inventor: IMAI TETSUYA
IPC: B01J23/63
Filed: 1993-05-25
Abstract: PURPOSE:To improve low-temperature igniting property and permit stabilized combustion at a high temperature by a method wherein the combustible gas is burnt by arranging specified catalysts at a fore stage and an after stage respectively. CONSTITUTION:A catalyst, constituted of a bearer containing a composite oxide consisting of a single compound, or two or more of oxides selected from alumina, silica, titania or zirconia, and an activating constituent of palladium oxide borne by said bearer, is arranged at a fore stage (inlet side of gas) while another catalyst, consisting of a bearer containing the oxide of rare earth elements and palladium oxide as well as the oxide of rare earth elements, which are borne by said bearer, is arranged at an after stage. When most hardly combustible methane, for example, is burnt, the oxidation of methane is started in the fore stage catalyst at 400 deg.C or lower while the temperature of the fore stage catalyst layer is controlled so as to be lower than 700 deg.C and the temperature of the after stage catalyst is controlled so as to be within the range of 700-1000 deg.C. According to this method, low-temperature igniting property can be improved.

Title: Optical writing device
Inventor: YAGI MICHIO
IPC: B41J2/44
Filed: 1990-05-11
Abstract: PURPOSE:To prevent color slurring in a subscanning direction and the lowering of resolution by providing an automatic correcting mechanism for a writing position. CONSTITUTION:Writing light sources 1a-1c are allowed to emit light so as to detect what position in the subscanning direction of a photosensitive body 4 the light in an initial state exists on. When the fixed positions of the light sources 1a-1c are correct, the intended specified cell of a sensor 6 detects the light. However, when the mounting position of the light source is deviated, light irradiating position is varied corresponding to the variation of the position, and the cell of the sensor 6 which detects the light differs from the specified cell which is intended at the beginning. By utilizing this effect, a write timing correction signal generation part 7 measures what cell of the sensor 6 actually detects the light, judges the position of the appropriate writing head line of each color, and generates a correction signal at the time of performing a writing action. Thus, the writing positions by the respective light sources are made coincident and the deterioration of image quality is prevented.

Title: Image forming device
Inventor: MORIZAKI HIROSHI
IPC: G03D13/00
Filed: 1990-05-11
Abstract: PURPOSE:To eliminate needless winding back and to prevent jamming of a photosensitive recording medium by stopping carrying the photosensitive/pressure sensitive medium in a reverse direction when the carrying in the reverse direction is judged to be impossible. CONSTITUTION:A normal image forming process is carried out when there is a large remaining quantity of microcapsule paper 12, and winding back operation of the microcapsule paper 12 of unexposed part is carried out after image formation. As the image forming operation is repeated, the microcapsule paper 12 is wound up to a winding up shaft 24. Then, when the remaining quantity of the microcapsule paper 12 becomes smaller, and a position where the winding back operation is impossible if carrying is proceeded further, an end indication hole 42 is detected by a photosensitive paper end sensor 39, and the winding back operation is inhibited for the following image formation. Thus, jamming is not generated in the photosensitive recording medium, and needless operation is evaded.

Title: Method for detecting drying state of wick
Inventor: ISHIDA MASAAKI
IPC: G01N25/62
Filed: 1989-05-17
Abstract: PURPOSE:To detect the drying trend of a wick accurately by judging that the wick is in the drying trend when the temperature which is detected at the end of a second temperature detecting part reaches a predetermined value. CONSTITUTION:A wick 3 is suspended from the upper part of a wick pan 4. A lower end part 31 of the wick is dipped into water 41 which is stored to a specified water level in the wick pan 4.

The temperature detecting ends 1 and 2 are thermocouples. When the temperature which is detected with the second temperature detecting end 2 reaches the predetermined value, it is judged that the wick 3 starts drying. Thus the drying trend of the wick can detected accurately.

Title: Recording device
Inventor: KIKUJI IKUO
IPC: B65H23/182
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent printing quality from being deteriorated by drag exerted on a recording medium and to perform high-quality and high-performance printing by providing an ejection means at a higher position than a recording medium carrying guide to such an extent that the recording medium is perpendicular to a carrying direction by the recording medium carrying guide. SOLUTION: A photosensitive material ejection roller 20 and an auxiliary roller 21 are provided at the positions higher than the photosensitive material carrying guide 25 by height Y or more. Namely, the height Y is such height that photosensitve material 11 is vertical at a nip point X to a horizontal carrying direction by the guide 25 on an upstream side in the carrying direction of a sagging forming part T. Thus, the drag generated at the nip point X acts on the material 11 only as a component in perpendicular direction to the carrying direction by the guide 25 and does not act as a component in the direction of the same surface as the carrying direction. Therefore, the sagging of the photosensitive material 11 formed in the sagging forming part T at the time of finishing the ejection does not exert any influence in the horizontal carrying direction.
