Title: Cvd method and apparatus
Inventor: NAKADA KIYOKAZU
IPC: B01J19/12
Filed: 1986-08-22
Abstract: PURPOSE:To make reaction efficient by drastically enhancing the activation of raw material gases, by activating and reacting the raw material gases by irradiating the raw material gases supplied into a reduced pressure casing with a plurality of laser beams having different wavelengths. CONSTITUTION:After both gases of SiCl4 and CH4 are excited by Ar-ion laser, an exciting part is irradiated with CO2 laser to allow the part to absorb CO2 laser. That is, by irradiating the raw material gases 4 excited by the Ar-ion laser of first laser beam 11 with the CO2 laser 12 of second laser beam, the synthetic reaction of SiC is performed perfectly and efficiently. When only the first laser beam 11 is used, Si becomes excessive and, further, there is a problem in productivity because no large output is obtained but, by using the large output CO2 laser as the second laser beam, SiC reaction advances perfectly.

Title: Pressure sensor and pressure detector using the same
Inventor: HORI MASAMI
IPC: G01L19/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To prevent a sensor chip property from being changed by a protective material applied to the surface of a printed substrate. SOLUTION: A glass made pedestal seat 2 jointed on one end with a sensor chip 1 is attached to the rear surface side of a printed substrate 3. Further, the sensor chip 1 and a square tube-like frame surrounding the periphery of the sensor chip 1 and the pedestal seat 2 are provided on the rear surface side of the printed substrate 3. A protective material (silicon gel 5) for improving the humidity resisting property is applied to the outside of a frame body 4 on the rear surface of the printed substrate. The periphery of the sensor chip 1 is thus surrounded by the frame body 4, so that in a bubble removing process for removing bubbles produced in pouring the silicon gel 5, the silicon gel 5 crawls up on the outside surface of the frame body 4, while the silicon gel does not get over the framebody 4 to cover the sensor chip 1.  Thus, troubles of changing the property of the sensor chip 1 can be prevented.
