IPC: H03H3/08
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To provide the substrate mounting method of a SAW filter chip for increasing a substrate mounting density at a low cost. SOLUTION: In this substrate mounting method, sealing walls 8 and 10 are formed on this SAW filter chip 1, and the sealing walls 8 and 10 are tightly adhered to the conductor pattern 22 of a substrate 20. As a result, a space on a chip surface 24 where a SAW filter is formed is turned to a tightly sealed space by the SAW filter chip 1, the sealing wall 10 and the substrate 20, and the SAW filter chip 1 is mounted to the substrate 20 with its face down. At the mounting of the substrate, since an area occupied by the SAW filter chip 1 can be about the size of the chip, the substrate mounting density is enhanced. Also, since the SAW filter chip 1, the sealing wall 10 and the substrate 20 are used as a sealing body, the number of components and, the number of manufacture processes are reduced as well and a manufacture cost can be suppressed to be low.

Filed: 1988-11-18
Abstract: PURPOSE:To adjust the irradiation position of a light beam simply by using a filter optical system of wavelength selecting performance, and splitting the light beam into the transmission object system and the observing optical system. CONSTITUTION:A transmitter 10 uses a dichroic mirror 11 to separate a light beam LA 1 sent to a transmission object and a light beam LA 2 made incident in a telescope 7. The mirror 11 constitutes a filter optical system in which most of the beam LA 1 is transmitted, a part of it is reflected and an observed light LA 4 incoming from the transmission object i5 reflected as the wavelength selectivity, and the telescope 7 constitutes the observing optical system observing the light beam LA 3 reflected in the corner cube prism 6 system together with the observing light LA 4 reflected in the filter optical system. Thus, the luminous quantity of the beam LA 1 is increased to reduce the luminous quantity of the beam LA 1 fed back to the light source 2 and the luminous quantity of the observing light LA 4 is increased.
