Patent JP-S6428954-A (JP)
Title: Manufacture of semiconductor device
Inventor: OZAWA TADASHI
IPC: H01L29/872
Filed: 1987-07-24
Abstract: PURPOSE:To reduce a stepped difference of an opening part at a forming region of electrode wiring, by piling a polycrystalline silicon layer on the opening part formed in an insulation film on a silicon substrate and next by forming an insular oxide film at least inside the opening part and afterwards by removing this oxide film and forming an electrode wiring on a region where the oxide film is removed. CONSTITUTION:An N<+> type burial layer 12 is formed on a P type silicon substrate 11 by means of diffusion of arsenic ions or the like, and next an N type epitaxial layer 13 is formed on the layer 12 and oxidized to form an oxide film 14. After photolithography is then used to form an opening part 10 in the oxide film 14, a polycrystalline silicon film 18 is made to grow on the whole surface. This polycrystalline silicon film 18 is provided with selective oxidation, and an insular oxide film 17A and an oxide film 17B are formed inside and outside the opening part 10 respectively. The insular oxide film 17a is etched/removed to expose a surface of the N type epitaxial layer 13. Metals such as platinum, aluminium, and the like are stuck on the surface and provided with heat treatment, so that an electrode wiring 20 is formed by patterning. Since a stepped difference of the opening part 10 is thus made smooth, no disconnection occurs in the electrode wiring 10.

IPC: G02B7/28
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a stereoscopic photographing device that can comfortably photograph an object without giving a sense of displeasure to a photographer and a person viewing a photographed picture. SOLUTION: The stereoscopic photographing device controls a convergent angle of two optical systems that collects the light from an object to form an optical image on an image forming plane depending on the distance up to the object. In this case, a lens microcomputer 412-1 has functions provided with a reliability confirming means 11, a convergent angle fixing means 12 and a reference angle generating means 13, and fixes the convergent angle to a prescribed angle, that is, to fix the convergent angle of the two optical systems equivalent to an angle in the case that the object distance is 1.5-3 m when, e.g. a photographer suddenly changes the object or it is discriminated that the reliability of a range finding signal is low due to a sudden change in a range finding signal resulting from the moved object disappearing from the photographing range.  Furthermore, a luminance signal 43 from the object can change the congestion angle of the two optical systems.

IPC: F23C10/18
Filed: 1986-08-07
Abstract: PURPOSE:To maintain the temperature of the fluidized bed at a high temperature to obtain a high combustion efficiency by supplying as a fluidized substance a dead-burnt alkali earth metal oxide to the fluidized bed and to set the temperature of the fluidized bed to a specified temperature or higher where the dead-burnt alkali earth metal oxide does not substantially cause a desulfurization reaction. CONSTITUTION:A fluidized bed 4 is provided on the upper side of a wind box 2 through an air dispersing plate 3, and a free board 5 is provided on the upper side of the fluidized bed 4.

A dead-burnt alkali earth metal oxide such as dead-burnt quick lime or the like is charged into the fluidzed bed through a dead-burnt quick line supply port 8. Dead-burnt quick lime has a hardness smaller than that of silica sand or alumina and the heat transfer tube is also less worn. Further, when the dead-burnt quick lime is compared with quick lime or light-burnt quick lime, the amount to be supplied of the former may be less than that of the latter, and hence the former is economical. By setting the fluidized bed temperature at a value equal to or higher than 900 deg.C where no desulfurization reaction substantially occurs, the amount of quick lime can be made smaller, and further a high combustion efficiency is obtained and a high temperature exhaust gas is obtained.

Patent JP-H0637854-A (JP)
Title: Data transmitter
Inventor: YAMAURA HIDEO
IPC: H04L29/08
Filed: 1992-07-15
Abstract: PURPOSE:To shorten the data transmitting time and to improve the responsiveness of the reception side even with just a single transmission line. CONSTITUTION:The cyclic counters 13 and 20 produces the address signals which are approximately synchronous with each other based on the reference clocks produced by the independent clock generators 11 and 18. Therefore the operation of a multiplexer 14 which selects the data by the address signal and turns these data into the serial ones is synchronous with the operation of a demultiplexer 21 containing a latch which turns the received data into the parallel ones. Then the parallel data equal to the received one can be acquired at the reception side. Under such conditions, the counter 13 produces a reset signal to secure the synchronization between both address signals. Then the reset signal is ternarized by a ternary level converter 16 together with the parallel data and sent to a ternary level restorer 17. A reset signal 70 separated by the restorer 17 resets a divider 19 and the counter 20 to secure the synchronization between both address signals in each cycle.
