Title: Portable terminal device
Inventor: OMAGARI KOJI
IPC: G06F3/0354
Filed: 1993-12-14
Abstract: PURPOSE:To prolong the time of operation by an internal battery by converting the turning force of a track ball into electric power and charging it in the internal battery. CONSTITUTION:When the track ball 11 is used for application software, the turning force of the rotary ball of the track ball 11 is transmitted to a motor for power generation through a mechanism part 12 and converted by the motor 13 for power generation into electric power, which is sent to a charging circuit part 14. The charging circuit part 14 converts the electric power sent from the motor 13 for power generation into a constant current. Then when the device is operated by, for example, a 2nd battery 27 and the electric power is charged in a 1st battery 26, a 1st switch 22 and a 3rd switch 24 are closed and a 2nd switch 23 and a 4th switch 25 are opened. When the 2nd battery 27 nearly comes down, the respective switches are inverted in state to operate the device by the 1st battery and start charging the 2nd battery 27.

Filed: 1987-12-10
Abstract: PURPOSE:To increase the breakdown strength of a trench capacitor, by a method wherein, after a defective part composed of protrusions or saw-toothed unevenness caused by trench etching is coated with titanium, heating is performed to form titanium silicide, and the defective part only is dissolved and eliminated. CONSTITUTION:On an Si substrate 1 on which a silicon oxide layer 2 is formed, a resist layer 3 is formed. In the state where a window is made selectively in this layer, RIE is performed to form a deep trench. After the above resist layer is eliminated, a titanium metal layer 8 is formed on the Si substrate, and titanium silicide 10 is formed by heat-treating the silicide substrate. A trench forming method is applied, wherein titanium silicide, titanium layer and the silicon oxide layer are dissolved and eliminated. In order to coat only the defective part with Ti, and dissolve only silicide without dissolving Si of the substrate at the time of eliminating silicide, a silicon oxide layer is arranged on the Si substrate, and it is prevented for Ti to come into direct contact with Si on other parts except trench forming position. Further, hydrofluoric acid which does not dissolve the Si substrate is used as a solution to dissolve silicide, and the defective part only is eliminated.
