Title: Surface working method for existing facing wall
Inventor: YANAGIDA HIROAKI
IPC: B44C1/20
Filed: 2000-06-14
Abstract: PROBLEM TO BE SOLVED: To provide a surface working method mainly for an existing deteriorated ceramic facing wall and an existing deteriorated ceramic facing panel, which is excellent in workability, cost efficiency, design value, and durability. SOLUTION: The surface working method for the existing ceramic facing wall and the existing ceramic facing panel is carried out in the following manner. First, driving forces are applied to a surface of each of the existing ceramic facing wall and the existing ceramic facing panel by using a driving instrument, such that a driving location and a driving depth of the instrument is numerically controlled. Next, an uneven pattern exposing substrate texture and including different depth portions is formed while an existing surface finish layer is separated. Then, a new surface finish layer is formed on each of the external wall surface and the panel surface. This surface working method is more excellent in workability than a conventional reforming technique and a surface working technique, drastically shortens a construction period, provides good adhesion to an undercoat material for use in re-finishing of the surface, and ensures sufficient durability. Further, this method is advantageous in that scaffolding in various types set in the construction site when reforming such as ordinary re-spray-coating takes place, is available as it is, and therefore this method is excellent in workability and cost efficiency.

Title: High frequency semiconductor device and its fabricating method
Inventor: TANNO HIDEAKI
IPC: H01L21/28
Filed: 2000-06-20
Abstract: PROBLEM TO BE SOLVED: To solve a problem that electric characteristics are varied and fabrication yield is lowered when a thin emitter region is formed for a high frequency silicon bipolar transistor through thermal diffusion by introducing impurities into a polysilicon layer because thermal diffusion rate is high in polysilicon and diffusion is ended before a device is settled.

Since the device can be operated in stabilized state, a semiconductor device having uniform electric characteristics can be provided. Furthermore, productivity can be enhanced because the diffusion time can be controlled by the filming temperature of the first polysilicon layer.
