Title: Printed wiring board
Inventor: SAITO ICHIRO
IPC: H05K1/11
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for manual soldering correction operation for dense mounting by forming a printed wiring board with a printed substrate where a soldering land is formed and a surface-mount part which is subjected to flow soldering to the soldering land and forming the soldering land so that at least one edge part is narrower than the width of a middle part. SOLUTION: Soldering lands 11 and 12 are common lands where two parts 6 and 7 are soldered and soldering lands 13 and 14 are exclusive lands for the parts 6 and a width W3 at the side of the other parts 7 is gradually increased as compared with a width W4 of the opposite side, thus attracting the two parts 6 and 7 mutually in the direction of an opponent side due to the surface tension of melted solder. In this manner, by changing the width of the soldering lands 11-14 and operating the tension of solder so that the two parts 6 and 7 attract each other, the two parts are adhered, thus achieving dense mounting in reflow soldering.

Title: Semiconductor optical element and its manufacture
Inventor: HATAKEYAMA MASARU
IPC: H01S5/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide semiconductor optical element in which the wavelength composition of an active layer is made uniform in every part of the active layer, by a method wherein the width of a stripe-shaped dielectric thin film or the width of a wavelength region is changed in every part of an optical waveguide according to an angle which is formed by the stripe direction of the optical waveguide and a [011] crystal orientation. SOLUTION: An SiO2 mask is formed on an n-InP substrate in such a way that the stripe direction of an input/output waveguide becomes a [011] crystal orientation. Then, an S-shaped active layer part 101 has a stripe shape whose length in its length direction is about 350 μm and that the offset of the optical axis of the input/output waveguide is about 30 μm. In addition, the width of the mask becomes continuously narrow according to an increase in a waveguide angle from about 35 μm at a wavelength angle of 0 deg., the width of the mask in the central part of an element is about 27 μm, and the opening width of the mask is constant at about 0.7 μm in every part of the element. By using a pattern which is formed in this manner, a bulk layer is formed by an MOVPE (metal organic vapor epitaxy) selective growth operation.  As a result, an active layer whose wavelength composition is uniform is formed.

Title: Thermal head
Inventor: YAMAMOTO SHIGERU
IPC: B41J2/335
Filed: 1988-10-19
Abstract: PURPOSE:To reduce the deviation between a center of curvature and a center of a band-like projection part by a method wherein groove parts are formed at both side riser parts of the band-like projection part on the surface of a substrate, and a glass layer is burnt to coat the substrate. CONSTITUTION:Since groove parts 1b are formed at both side riser parts of a band-like projection part 1a on a surface of a substrate 1, paste, i.e., glass applied thereonto becomes liquid in burning to flow. However, it flows into the both side groove part 1b, and no riser is generated on side face parts of the band-like projection part 1a. Therefore, a radius of curvature of a surface of a glass layer 2 on the band-like projection part 1a is lessened and besides, the deviation between a center of curvature of the glass layer 2 having this radius of curvature and a center of the band-like projection part 1a becomes very small. Therefore, improvement of printing quality of a thermal head can be achieved and besides, improvement of thermal response and thermal efficiency can be achieved. Further, a part between lead electrodes 4, 4 of this band-like projection part 1a is made to be a thermal resistor 6. Furthermore, a protective film 7 is formed over all the upper surfaces thereof.
