Title: Manufacture of electronic part
Inventor: TAKAHASHI MUNEKO
IPC: H03H3/08
Filed: 1995-06-12
Abstract: PURPOSE: To simplify the formation of electrodes by forming a photoresist layer on a SiO2 -based film formed on a substrate, removing the film and the photoresist from electrode formation areas to obtain electrodes, and then dissolving the SiO2 film in HF solution. CONSTITUTION: A porous SiO2 -based film 2 is formed on the surface of a piezoelectric substrate 1 by CVD at relatively low temperature. A resist pattern 3a is formed on the film 2, and the film 2 is etched using the resist pattern as a mask so that the SiO2 film 2 will be smaller than the area of the resist pattern 3a. Au/Cr electrodes 4 are evaporated using the resist pattern 3a and the SiO2 film 2 as an evaporation mask. Then the workpiece is immersed in HF solution, and the SiO2 film is thereby dissolved to obtain electrodes 4. The porous quality of the SiO2 film 2 facilitates the osmosis of HF and makes the SiO film 2 easily soluble even in HF of low concentration.

Title: Packet switch
Inventor: OKAMOTO SATOSHI
IPC: H04L12/931
Filed: 1991-06-17
Abstract: PURPOSE:To allow the switch to be compatible with a high line speed and to improve the fault resistance performance by arranging plural variable wavelength optoelectric converters corresponding to outgoing lines and starting revision of a selected wavelength in advance according to a reservation table respectively. CONSTITUTION:A control section 14 sets identification of a wavelength to be selected corresponding to outgoing lines among output optical signals from an optical coupling distributer 13 to a reservation table 15. Then a variable wavelength optoelectric converter 16 makes conversion for each time slot and only the converted signal is outputted to an outgoing line 17 and a converter corresponding to other time slot is inactive and the wavelength is revised into the selected wavelength according to the set identification in the reservation table 15. Thus, the revision to the wavelength selected by each time slot is started in advance to allow the switch to be compatible with a high line speed. Furthermore, since converters are plural, when a fault takes place in one converter, the operation is continued by using the other converter.

Title: Antenna changeover device
Inventor: ARIMA KENJI
IPC: H04N5/44
Filed: 1985-07-02
Abstract: PURPOSE:To prevent the deterioration of a picture quality of a received picture by changing over an antenna only when a difference between the output of a level detecting means for extracting a signal level of the antenna and the level deciding the antenna used at that time exceeds a value determined by a level difference setting means. CONSTITUTION:The receiving level of respective antennas is extracted in a level detecting gate circuit 8, passes through a level difference setting circuit 10 and is inputted to a level comparison circuit 12. The level comparison circuit 12 compares the output of the level difference setting circuit 10 with an output of a level sampling hold circuit 7 and outputs a pulse of high level only in an interval indicating the high level of the output of the level difference setting circuit 10. When viewing from the level comparison circuit 12, the level difference is constantly added to the output from the level detecting gate circuit 8 by a resistance division with respect to a hold level of the level sampling hold circuit 7. Thereby, a frequency changeover of the antenna for a small change of an electric field can be stopped by a simple circuit.
