Filed: 1982-02-16
Abstract: PURPOSE:To form a porous Si layer with uniform thickness and density by a method wherein a dielectric layer of SiO2, etc. is formed on the back surface of the si layer instead of a metallic electrode layer, and next an AC electrolysis is performed. CONSTITUTION:An SiO2 layer 12 is formed on the back surface of an Si substrate 13, and it is mounted on a support body 11. The support body 11 has a stainless steel electrode plate 14, which is contacted on the back surface of the substrate 13. The substrate 13 is exposed only in the surface to apply to a formation treatment, and sealed so that an electrolyte 16 does not infiltrate into the other part. When an AC voltage is impressed between an opposed electrode 15 and the electrode plate 14 resulting in an AC electrolysis, the porous Si layer is formed. This Si layer is converted into an SiO2 by a thermal oxidation in a later process, and accordingly becomes an insulation isolation layer. Thereby, a porous Si layer with uniform thickness and density can be formed.

Title: Electro-acoustic converter
Inventor: SUZUKI KAZUSHI
IPC: H04R13/00
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a solder two-piece division phenomenon by shaping a land part of a lead terminal approximately circularly and allowing the natural diffusion shape of dropped liquid solder to coincide with the shape of the land part. SOLUTION: When a current is allowed to flow into a coil 9 through lead terminals 21, 23, an iron core 7 is converted into an electromagnet and a magnetic field is generated on the tip of the iron core 7. When a magnetic pole generated on the iron core 7 by the coil 9 is different from a magnetic pole generated on a magnet 13 included in a diaphragm 17, the diaphragm 17 is attracted to the iron core 7. When the magnetic poles are the same, the diaphragm 17 and the iron core 7 are mutually repulsed. When the diaphragm 17 is oscillated by prescribed frequency due to the attraction/repulse, a sound is generated. Both the coil ends 9a, 9b of the coil 9 are drawn out to the surface of the land parts 21a, 23a of the lead terminals 21, 23 and soldered.  When the land parts 21a, 23a are formed like circles, fluid solder is diffused like circles or domes, and when the shape of the solder is a circle, the shape coincides with a diffusion shape, so that the division of solder into two parts can be prevented and the generation of defect connection can be prevented.
