Abstract: PURPOSE:To eliminate the overlapped parts of second layer charge transfer gate electrodes with first layer charge transfer gate electrodes, to decrease the widths of the first layer gate electrodes and to make fine the whole device by a method wherein the second layer gate electrodes are formed using an etchback method. CONSTITUTION:A polysilicon film 7 consisting of the material for second layer charge transfer gate electrodes 4 is made to deposit on first layer charge transfer gate electrodes 3 and a first layer gate insulating film 2. A resist is applied in such a way that step parts, which are situated on the polysilicon film 7, of the electrodes 3 are filled and a baking is performed to flatten the surface of the film 7. Then, the resist is removed by dry etching leaving the resist on step parts, at which the electrodes 4 are formed, between the electrodes 4. Then, the film 7 is removed except the step parts by dry etching using the left resist as a mask, the resist left on the step parts is removed and the electrodes 4 are formed. Thereby, the widths of the electrodes 3 are decreased and the whole device can be made fine.

Abstract: PURPOSE:To produce energy more than consumed amount by fixing units, each comprising an electrolytic unit and a fuel cell unit, to an endless rail for moving the units vertically. CONSTITUTION:Single or a number of units, each comprising an electrolytic unit and a fuel cell unit, are fixed to an endless rail for moving the units vertically. When two units, for example, are fixed at the top and bottom dead centers of the endless rail, the electrolytic unit in a unit fixed at the bottom dead center decomposes water into 2H2 and O2 thus producing buoyancy. The unit at the top dead center lowers gravitationally, and the endless rail starts motion. When respective units reach the top and bottom dead centers, same function takes place again and the endless rail continues same motion.

Filed: 1988-12-20
Abstract: PURPOSE:To shorten a time required for automatic tracking by performing IF count after searching the same program station with the most intensive wave in reception electric field strength at the time of performing automatic channel selection. CONSTITUTION:When the reception electric field strength is lowered according to the movement of a vehicle in the case of reception while driving with an automobile, a frequency list AF signal is read out first, and the reception is performed by switching a broadcast station to another one from a frequency list (at this time, no IF count is performed). Next, the reception electric field strength is checked. After the station with the most intensive reception electric field strength is searched by repeating such operation, the IF count is performed, and it is confirmed whether or not the reception is performed with a correct frequency. Furthermore, it is confirmed whether or not the station is the same program station by checking a program identification PI code. In such a manner, the automatic tracking can be accelerated.
