Abstract: PURPOSE:To prevent wiring disconnection by forming SiO2 by the selective oxidation method while using Si3N4 as a mask and making the SiO2 film side face around electrode windows into a gentle inclination. CONSTITUTION:Required N<+>-type and P<+>-type layers are selectively formed on N-type Si substrate 1 by a SiO2 mask, and after that, the mask is removed to generate SiO2 film 9. CVD Si3N4 is provided on film 9 and is opened selectively to generate mask 10. Next, SiO2 11 is generated to warp upward the part around mask 10 by oxidation at approximately 1000 deg.C. Next, film 10 and film 9 under film 9 are removed to expose substrate 1, and SiO2 12 and 13 are generated on the exposed surface by oxiding thermally again. Film 13 is after used as a gate film. After that, after the processing in N2 at approximately 1000 deg.C, film 12 is provided with electrode windows to evaporate Al, and gate electrodes 14 and 15 and source drain wirings 16 to 18 are generated and are covered with PSG 19.

Title: Three-dimensional speaker directional pattern estimating method
Inventor: OSAWA KUNIAKI
IPC: H04R1/32
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To provide three-dimensional directional pattern data by spline- interpolating a non-existing data part by utilizing the horizontal and veridical directional pattern data. SOLUTION: Supposing that data on α=0-180 deg. relating to β=0, 90, 180, 270 deg. exist as catalog data, the horizontal and vertical directional pattern data is input (step 1). In order to calculate the directional pattern data at every 1/3 oct. in an audible range, a band loop is operated (step 2) and whether data exists or not is confirmed (step 3). In the case of no data, 10 dB non-directional pattern data of dummy is provided (step 4) and the loop of the next band is operated. In the case where data exists, loop is operated at every 5 degrees until α=5-175 deg. (step 5), spline interpolation is used from the sound pressure level data of β=0, 90, 180, 270 degrees for each α to create data at every β=5 degrees (step 6). Thus, it is possible to create three-dimensional directional pattern data in a speaker single unit + a speaker box in each band.

Filed: 1981-09-30
Abstract: PURPOSE:To eliminate shield preventing the effect of harmonics and a filter for harmonic suppression from a radio equipment, by using a micrwave absorbing body for a transistor spacer inserted to terminal leads of a transistor (TR). CONSTITUTION:A spacer 17 for an annular microwave absorbing body is inserted to a lead of an emitter E of a TR16 used with common emitter connection and fitted to a printed board 18. In connecting a radio frequency oscillator 19 to a base B of the TR16 and inputting a signal (ib) to the base B, a signal ib.beta flows to the emitter E. The beta is a current amplification factor. A microwave component out of the radio signal of ib.beta is attenuated at this spacer 17. Thus, a shield preventing the effect of harmonics can be eliminated from a radio equipment and a filter for harmonic suppression is eliminated or the attenuation at the outside of the band of the filter can be reduced.

Abstract: PURPOSE:To record, display, hold, and rewrite information directly and to requires almost no electric power for all functions them by forming a transparent conductive piece on the surface of light transmissive ceramic which causes birefringence when impressed with a voltage, and generating a potential difference by using a head for voltage impression. CONSTITUTION:Counter electrodes are formed on a PLZT substrate and the voltage is impressed between those electrodes to cause birefringence on the PLZT substrate. For the purpose, a polarizing film is arranged on both surfaces of the PLZT substrate and then there is a difference in brightness between the part where the birefringence is cause and other parts to make a display. When a switch is opened while the voltage is impressed to the PLZT substrate, the birefringence caused on the PLZT substrate is maintained and a storage state is entered. This is reset by short-circuiting the electrodes.
