Abstract: PURPOSE:To further refine microstructure without reducing punch-through withstanding voltages by a method wherein a gate insulating film is etched, with a resist film retained on a previously-processed gate electrode and on its sides acting as a mask, and source, drain layers are provided by self-alignment. CONSTITUTION:A resist 5 is applied on a resist 4 retained after being used for the formation of an electrode 3. The resists 4, 5 are removed by etching, except a portion of the resist 5 located on the sides of the electrode 3. The electrode 3 and the retained resist 5 work as a mask and an insulating film 2 is subjected to etching, which results in the gate insulating film 2 wider than the electrode 3. Next, impurities are diffused, for the formation of a source 6, drain 7. In a device designed as such, the distance between a drain and source is larger than the width of the gate electrode 3. It follows therefore that withstand voltages may be maintained and patterns further refined in the presence of lateral diffusion of impurities.

Title: Spread spectrum communication system
Inventor: HIRAMATSU TATSUO
IPC: H04J13/00
Filed: 1990-04-27
Abstract: PURPOSE:To omit the synchronization of phases of the PN codes on the reception side with the transmission side by generating a spread spectrum signal, regenerating a carrier signal demodulated by an ON/OFF keying signal from the spectrum diffusion signal, and detecting the carrier signal for output of the ON/OFF keying signal. CONSTITUTION:A gate circuit 13 applies a carrier signal received from an oscillator 14 to a spread spectrum part 15 for an ON period of an ON/OFF keying signal. A multiplier 17 multiplies the 1st PN code received from a PN code generator 16 by the output signal received from the circuit 13. Meanwhile the spread spectrum signal received via a reception antenna 21 is applied to an adverse spread spectrum on part 22. Then a multiplier 24 multiplies the 2nd PN code received from a PN code generating part 23 by the received spread spectrum signal. The output of the multiplier 24 undergoes the envelope detection via a detector 26 and through a BPF 25, and this detected output is applied to a decoder 27. Thus it is not required to secure the synchtonization of code phases on the reception side.

Abstract: PURPOSE:To detect the concn. of oxygen over a wide range, in a limit current type oxygen sensor, by forming diffusion holes having different sizes to both surfaces of a solid electrolyte plate and respectively operating said holes corresponding to the concn. of oxygen. CONSTITUTION:Diffusion holes 4a, 4b having different sizes are formed to the caps 3a, 3b surrounding the electrodes 2a, 2b formed to both surfaces of a solid electrolyte plate 1 to form spaces 8. A limit current is proportional to the opening areas of the diffusion holes in which oxygen flows. Therefore, when the concn. of oxygen is high, the electrode 2a is set to a cathode and the smaller hole 4a is operated as an oxygen inflow port while the larger hole 4b is operated as an oxygen discharge port. Contrarily, when the concn. of oxygen is low, the electrode 2b is set to a cathode and the larger hole 4b is operated as an oxygen inflow hole while the smaller hole 4a is operated as an oxygen discharge hole. By this constitution, only by changing the DC voltage applying direction to the electrodes 2a, 2b, a limit current is obtained over a wide oxygen concn. range and the concn. of oxygen is detected.
